Description

LAMINATING FRAME FOR ABSORBING LAMINATED FORCES DESCRIPTION OF THE INVENTION The invention relates to a rolling frame for absorbing rolling forces of at least three cylinders respectively mounted in bearing on both sides in rolling seats of the rolling frame that absorb the rolling forces, at least the bearing seats of A cylinder is disposed in each case in a frame body together with a bearing seat of another cylinder.

Rolling frames of the type under consideration are well known in the art, and have long been used successfully in connection with the rolling of drawn products. These rolling frames serve as bearing frames in which the cylinders inserted in the cylinders are mounted rotatably, whereby the cylindrical elements immobilized on these inserted cylinder shafts form a central gauge opening, through which they are made Pass the stretched product to laminate it. In the respective rolling frame, several cylinders are arranged on one level, most often three or four cylinders. To be able to laminate several times immediately in succession a product In the case of stretching, which is conducted along a rolling line or axial processing path, a plurality of rolling frames of the type are generally arranged along the rolling line or axial processing path. under consideration It is understood that a conversion of this type of cylinder machines to another caliber or also a reconversion due to wear goes together with a correspondingly high conversion cost, since in each of the rolling frames it is necessary to change correspondingly the cylindrical elements immobilized on the cylinder shafts introduced to adjust the cylinder machine. For this purpose, the inserted cylinder shafts are removed from their bearing seats that are in the respective rolling frame and after changing the cylindrical elements are reinserted or inserted into the bearing seats. Frequently the rolling frames are designed as moving cassette units, which are supported to move radially relative to the rolling line or axial processing path.

It is the object of the present invention to perfect the rolling frames of the type under consideration so that a conversion of this kind be simplified at least as regards its adjustment.

The solution is based on the fundamental premise that the frame bodies in which the cylinders are mounted by way of bearing seats, and the associated bearing seats have a key function, when making the frame bodies and the bearing seats These are the essential functions of the rolling frame that are otherwise realized by frame plates and the connection to the frame bodies and consequently to the bearing seats. This fundamental premise can be carried out cumulatively or alternatively in various aspects.

The problem of the invention is solved by a rolling frame to absorb rolling forces of at least three cylinders respectively mounted in bearing on both sides in rolling seats of the rolling frame that absorb the rolling forces, being that at least the seats of one roller bearing are arranged in each case in a frame body together with a bearing seat of another cylinder, and the rolling frame being characterized in that one of the frame bodies respectively comprises fixed bearings of the two associated cylinders and / or one of the frame bodies comprises in each case floating bearings of the two cylindersassociates In this respect, in a first variant of the bearing assembly, the bearing seats of a frame body can comprise in each case fixed bearings of both cylinders associated with these bearing seats, so that the two associated cylinders are placed with accuracy and appropriately one relative to the other without large adjustment activities. In a second variant of mounting in rolling it is possible that the bearing seats of a frame body comprise in each case floating bearings of both cylinders associated with these bearing seats, so that it is therefore possible to effect an adaptation and adjustment of the position of this frame body in a simple manner and without complicated adjustment activities.

It is understood that optionally a frame body can comprise in each case fixed bearings and a frame body in each case floating bearings, so that it is therefore possible to realize the advantages cumulatively. Eventually the geometries do not allow a corresponding distribution in all the frame bodies, so that eventually one of the frame bodies must or may comprise both fixed bearings and floating bearings, which will eventually require a slightly more complicated adjustment.

By means of these two new variants of mounting in rolling, a particularly simple adjustment of cylinders is possible when converting to another caliber, since in particular no readjustment of the cylinder shafts at the locations of the fixed bearings is necessary. At the locations of the floating bearings the bearing seat of the respective cylinder shaft can be self-adjusting. Concerning this, the conversion of the rolling frames to another caliber is particularly simple.

Conveniently, by means of the present rolling frame, a rolling frame for universal use was created, which combines the advantages of the construction of inserted shafts in relation to a simpler cylinder change with the advantages of the construction of a retracted bearing assembly. in the cylinders, with an optimized cylinder diameter, as small as possible.

In the case of the present rolling frames, it is possible in particular to deal with both adjustable 3-roll and 4-roll rolling frames as well as non-adjustable rolling frames for the finishing of tubes, steel bars and wire, in particular with respect to a Rolling mill of exact dimensions, abbreviated MV, and of a train of lamination reduction by stretching, abbreviated SRW.

The rolling frames preferably house several cylinders disposed on a level, and driven, which form a central gauging aperture, whose cylinder shafts are ideally mounted rotatably in rolling frames configured as movable cassette units.

Accordingly, the present rolling frames can be used universally in all known forms of construction of fixed or also known rolling frames, with optimized cylinder diameter, where lamination frames with distribution of metal are also included in particular. internal drive via tapered roller bearings that mesh with one another (form I construction), as well as rolling frames in which the individual cylinder shafts are driven separately (form of construction in A).

The cylinder shafts are preferably made as inserted shaft elements, and it is possible that with a rack and a corresponding nut therewith be held torsion-free with the inner rings of the bearing units, the fixed bearings guarantee the axial positions of the cylinders and the floating bearings remain slidable via internal rings with multiple wedge profiles.

A method further provides that one of the frame bodies comprises both fixed bearings of the associated cylinders and the other of the two frame bodies the floating bearings of the two associated cylinders, since in this way in particular an adjustment can be obtained of simple cylinders.

According to another aspect of the invention, the present problem is solved additionally with an alternative lamination frame to absorb rolling forces of at least three cylinders which in each case are mounted in rolling on both sides in rolling seats of the rolling frame which absorb the rolling forces, wherein at least the bearing seats of one of the cylinders are respectively arranged in a frame body together with a bearing seat of another cylinder, and the rolling frame being characterized by the fact that the two frame bodies are connected in an exclusively effective force element between the two frame bodies and / or with a force element arranged radially to the outside and axial at the height of the cylinders and / or that the force element It is effective in parallel to the cylinder shaft.

Also by this it is possible to substantially simplify the adjustment of the cylinders by changing the cylinders, by virtue of the fact that with the appropriate configuration it is possible, in particular, on the one hand to connect the frame bodies directly to one another, without it being necessary to hold them together by means of additional mounting elements that occupy construction space and they must be assembled and disassembled additionally.

Ideally, the referred force elements can be arranged or provided inside the frame bodies, so that the force elements do not occupy an additional construction space outside the frame bodies. On the other hand, such a force element constructed in the frame body does not protrude or only negligibly since it generally extends substantially parallel with respect to the nearest cylinder shaft.

The concept of "force element" describes in the sense of the invention any functional body elements by means of which it is possible to establish a bodily non-positive connection between two functional components, such as for example the present frame bodies.

As an element of effective force between the two frame bodies, for example, a threaded element or an articulated element can be provided, this being Threaded element or articulated element only acts between two of the frame bodies.

It is understood that the force element arranged radially to the outside and axial to the level or in the region of the cylinders can be configured in multiple ways; for example, this force element may comprise a ring armature or the like.

According to another aspect of the invention, the present problem is also solved by a rolling frame for absorbing rolling forces of at least three cylinders which in each case are mounted in rolling on both sides in rolling seats of the rolling frame which they absorb the rolling forces, at least one roller bearing seat being arranged in each case in a frame body together with a bearing seat of another cylinder, the rolling frame being characterized in that all the bodies of frame positively join the rolling frame.

Thanks to the positive connection obtained by this, a particularly simple cylinder adjustment is also achieved by changing the cylinders, for example because an additional rolling frame frame can be dispensed with. In addition to this, it is possible to reduce the dimensions of the Laminate frame with a corresponding design.

It is particularly advantageous in this context if the force element comprises a threaded element or tie element, since this further simplifies the adjustment of the cylinders once more.

If the force element is arranged axially inside a gauge base, that is to say in the region of the deepest recess of the cylinders it can on the one hand be placed sufficiently centrally in a constructively simple manner. On the other hand it is possible by this to reduce the size of the rolling frame.

In this connection, it is advantageous if the force element is disposed cumulatively axially in the region of a cylinder recess of the rolling stand for a cylinder drive rod of the cylinders, so that a sufficient arrangement can be ensured by this. central. In addition, by this the force element is subjected as little as possible to tensile stress due to the rolling forces.

The problem of the invention is also solved by a rolling frame to absorb the rolling forces of at least three cylinders that are mounted in rolling on both sides in rolling seats of the rolling frame that absorb the rolling forces, wherein at least one roller bearing seats are disposed in each case in a fundamental frame body together with a bearing seat of another cylinder, wherein the lamination frame is characterized in that the two frame bodies are in contact with one another. with another via a contact surface.

Due to the fact that the two frame bodies are in contact with each other via a common contact surface, it is also possible to simpiitize the adjustment of the cylinders when changing them. This is due inter alia to the fact that the two frame bodies can interact in such a way with each other, that they are directly connected to one another, so that it is possible, for example, to dispense with an additional rolling frame frame or the like, by means of which it is possible to simplify in total the assembly work comprising a setting of the cylinders.

In accordance with another aspect of the invention, the imposed problem is also solved by a rolling frame to absorb the rolling forces of at least three bearing-mounted cylinders on both sides in bearing seats of the rolling frame which absorb the forces of laminate, wherein at least the bearing seats of a first cylinder are arranged in a frame body together with a seat bearing of another cylinder, the two frame bodies being directly connected via a contact surface.

In this regard, the two frame bodies are connected to one another so that they can constitute with operational safety a frame unit of the rolling frame which can be opened easily if necessary, due to which a reconversion It is very simple. By way of this contact surface it is possible, for example, to directly transmit between the two frame bodies the working forces or the like produced by the rolling, so that these two frame bodies can be directly supported in a mutual manner in reverse closing.

In this aspect the contact surface can be provided, similarly as the aforementioned force element, preferably in the region of a gauge base or in the region of a cylinder cut-out of the rolling stand, whereby again it is possible in particular to guarantee an effort as low as possible in the region of the contact surface.

Particularly in this context it is favorable that the connection is made via a link or via a detachable connection, such as a connection screwed.

If the contact surface is arranged in a region of low force it is possible that any articulated connections and threaded connections have smaller dimensions by virtue of which they must absorb less work forces or the like.

According to a further aspect of the invention, the problem imposed here is also solved correspondingly by means of a rolling frame for absorbing the rolling forces of at least three bearing-mounted cylinders on both sides in bearing seats of the absorbing laminate frame. the rolling forces, and wherein at least the bearing seats of one cylinder are arranged in a frame body together with a bearing seat of another cylinder, the rolling frame being characterized in that the two frame bodies are connected one with another in a region lacking in rolling forces of the rolling frame.

By this it is possible to guarantee that the force elements or other components and / or regions of the frame body connecting the two frame bodies are discharged as completely as possible, so that they can be dimensioned smaller, by which is It is also possible to save construction space.

In this respect, it is convenient that both frame bodies are connected to one another on one side of the cylinder opposite the rolling gauge.

In addition, the problem of the invention is also solved by a rolling frame to absorb the rolling forces of at least three cylinders mounted in bearing on both sides in rolling seats of the rolling frame that absorb the rolling forces, being that less the bearing seats of a cylinder are arranged in each case in a frame body together with a bearing seat of another cylinder, and the rolling frame being characterized in that the two frame bodies can be reciprocally displaced in a guide .

Also by this a particularly simple cylinder adjustment is achieved in a change of cylinders by virtue of which the two frame bodies are led towards each other when the cylinders are changed. It is understood that by means of this it is possible to substantially more simply project the manipulation of the frame bodies.

Conveniently the guide comprises two side frame plates, so that at least two of the frame bodies can be easily moved relative to one or more frame bodies of the frame of the frame. laminate. These frame plates can be provided in various ways. Preferably they are configured next to one of the two frame bodies, so that no additional components are required for this purpose.

Additionally it is also convenient that the guide is directly active between the bearing seats, for example as a rotating joint. By this it is possible to lower the frame bodies towards one another substantially central in the region of the cylinder elements, by means of which it is possible to project in a particularly simple manner the access to the cylinder elements.

The problem of the invention is also solved by means of a rolling frame for absorbing the rolling forces of at least three cylinders mounted on both sides in bearing seats of the rolling frame which absorb the rolling forces, at least the bearing seats of a cylinder are arranged in each case in a frame body together with a bearing seat of another cylinder, and the bearing seats, in particular at least one bearing provided in the bearing seat, can penetrate inside the associated cylinder.

Also by this it is possible to substantially simplify an adjustment of the cylinders by changing the cylinders, by virtue of which the bearing seat can then help for a preset. Additionally, with a proper configuration of the bearing seats, only a smaller construction space is required in the rolling frame, and this also independently of the common bearing seat mounting, which again is convenient for configuring a more construction space. little.

At this point it is worth mentioning that other substantial advantages of the present invention reside in that by means of the modular construction form of the rolling frame it is possible to obtain smaller, interchangeable assembly and fabrication units, such as rolling frames and cassette units and greater flexibility in manufacturing and acquisition. The chain of construction sizes is also extended. As already mentioned, a faster, simpler change of cylinders without disassembly of the roller bearings and / or tapered roller bearing units which have already been adjusted in the rolling frames and the corresponding frame bodies is also achieved.

It is also possible to obtain smaller dimensions of the rolling frame with the same load capacity of the rolling frame and the same bore diameter, whereby constructively an assembly is easily obtained. smaller cylinder diameter, optimized, better forming conditions, smaller dimensions of rolling frame with less rolling frame distance, better material production due to lower end losses, lower investment and operating costs and a compact construction form and stable with minimized space requirements.

It is understood that the characteristics of the solutions described in the foregoing and in the claims can optionally also be combined in order to then be able to realize the advantages in a correspondingly accumulated manner.

In the first exemplary embodiment shown in Figures 1 to 4, a rolling frame 1 comprises a total of three frame bodies 2, 3 and 4 in which three cylinders 5, 6 and 7 are mounted in a concentric manner around a line 8. of laminate or of an axially extending processing path, with the three cylinders 5, 6 and 7 forming an 8A gauge for laminating a rolling product not shown here.

Each of the cylinders 5, 6 and 7 is constituted by a cylinder shaft 9, 10 and 11 and an associated cylinder element 12, 13 and 14, these three cylinder elements 12, 13 and 14 forming the caliber 8A , as can be seen in particular very well according to the illustration according to figures 1 to 3.

The frame bodies 2, 3 and 4 are configured in each case angled, so that in each case for two of the three cylinder shafts 12, 13 and 14 provide a corresponding bearing seat 2A, 2B, 3A, 3B and 4A and 4B.

As can be seen in particular according to the representation according to FIG. 4, the first frame body 2 configures the two bearing seats 2A and 2B in the form of a first floating bearing 2C for mounting the first shaft 9 of cylinder and in the form of a second floating 2D bearing to mount in rolling the third shaft 11 of cylinder. Similarly, the second frame body 3 forms a first bearing seat 3A in the form of a first floating bearing 3C for mounting the first cylinder shaft 9 and a second floating bearing 3B in the form of another floating 3D bearing for mounting the second cylinder shaft 10 in the bearing. In the second frame body 3 there is also a fixed bearing 3E for axially immobilizing the first cylinder shaft 9. In addition to this, the third frame body 4 also configures a first bearing seat 4A and a second bearing seat 4B, where the second cylinder shaft 10 is mounted on the first bearing seat 4A and the second cylinder shaft 10 is rotatably mounted on the bearing. bearing seat 4B the third cylinder shaft 11, in Case house in the third body 4 of the frame. In this aspect the first bearing seat 4A is configured as the first fixed bearing 4C of the third frame body 4 and the second bearing seat 4B as the second fixed bearing 4D of the third frame body 4.

In this exemplary embodiment, the bearings 2C, 2D, 3C, 3D are in each case made as taper roller bearings in an X arrangement, while the first fixed 4C bearing and the second fixed 4D bearing are in each case made as bearings. of tapered rollers. The additional fixed 3E bearing is configured as a double-acting axial ball bearing.

As far as this is concerned, it is possible on the one hand to constructively replace very easily and on the other hand to mount rotary bearings in the rolling frame 1, the first cylinder shaft 9 around a first axis 15 for insertion and rotation, the second shaft 10 for cylinder around a second axis 16 for insertion and rotation, and the third cylinder shaft 11 around a third axis 17 for insertion and rotation. In order that a change of cylinder can be carried out quickly, the cylinder shafts 9, 10 and 11 are respectively made as inserted shaft elements (here not symbolized separately), as can be clearly seen, in particular according to the illustrations according to figures 2 and 3. A good The insertion of the individual cylinder shafts 9, 10 and 11 is ensured in a constructively simple manner by the fact that the individual cylinder shafts 9, 10 and 11 are not mounted directly on the respective bodies 2, 3 and 4 of the bearing. frame, but by means of corresponding bearing bushing elements 20 (here only symbolized in exemplary manner) as is already known from the prior art.

In accordance with the first exemplary embodiment, the bearing bush elements 20 are on the one hand configured directly as conical rollers 21, 22, 23 and 24. On the other hand, the bearing bushing elements 20 are constructed as a blind hole bushing 25 and as through bushes 26 and 27.

With the help of the conical rollers 23 and 24, the second cylinder 6 and the third cylinder 7 are in active contact with the conical rollers 21 and 22 of the first cylinder 5, so that the cylinders 6 and 7 - in a manner known per se they can both be driven by the first cylinder 5. In this regard, in the case of the first cylinder shaft 9 of the first cylinder 5 it is also an input shaft 9A.

The first cylinder shaft 9 comprises a total of four key profile zones 30, 31, 32 and 34 multiple By means of the first multi-key profile zone 30 it is possible to establish a drive connection with a drive element not shown here. A positive connection to the first conical roller 21 is established by the second multi-key profile zone 31. In a similar manner, a positive connection with the first cylinder element 12 is made by the third multi-key profile zone 32 and a positive connection with the blind hole bushing of the second roller by the fourth multi-key profile zone 33. 22 conical, provided that the first cylinder shaft 9 is inserted in the rolling frame 1 (see in particular figure 1).

In contrast, the second cylinder shaft 10 is only equipped with two multi-key profile zones 34 and 35, the second cylinder shaft 10 being in active contact with the third conical roller 23 via the respective first zone 34. of profile of multiple keys and positively connected to the second cylinder element 13 via the respective second zone 35 of multi-key profile.

Similarly, the third cylinder shaft 11 comprises two other multi-key profile zones 36 and 37, wherein the third cylinder shaft 11 is actively connected to the fourth conical roller 24 by means of the first zone 36 of the other multi-key profile zones. Via the second zone 37 of the other multi-key profile zones the third cylinder shaft 11 is in positive active connection with the third cylinder element 14, as long as the third cylinder shaft 11 is disposed inserted correspondingly in the rolling frame 1, which is shown for example well according to the representation according to figure 1.

According to the described structure of the rolling frame 1, the two bearing seats 2A and 2B of the first frame body 2 are configured in each case as floating bearings 2C and 2D. This also applies to the first bearing seat 3A and the second bearing seat 3B of the second frame body 3, by virtue of which the two respective bearing seats 3A and 3B are also configured in each case as floating 3C and 3D bearings . In this regard it is possible that after a conversion to another caliber 8A, the cylinders 5, 6 and 7 are aligned by automatically adjusting in the frame bodies 2 and 3 of the rolling frame 1 in relation to their positions, so that a Cylinder adjustment is simplified accordingly.

The second cylinder 6 and the third cylinder 6 are secured against an undesired axial displacement by means of the two bearing seats 4A and 4B of the third frame body 4, by virtue of which these are configured in each case as fixed 4C and 4D bearings. In order for the first cylinder 5 also to be secured against this type of undesired axial displacement, the second frame body 3, in addition to being equipped with the two floating bearings 3C and 3D, is also additionally with the fixed bearing 3E, by means of which the blind hole bushing 25 and thus also the first cylinder shaft 9 are mounted to the second frame body 3, correspondingly secured against axial displacement. Accordingly, the first frame body 2 only comprises floating bearings and the third frame body 4 only fixed bearings, while the second frame body 3 comprises both fixed bearings and also floating bearings and in this regard constitutes a mixed form. which is naturally inevitable with a cylinder arrangement of this type.

Accordingly, the third frame body 4 comprises two fixed bearings 4C and 4D of the associated cylinders 6 and 7 and the other frame bodies corresponding to these two cylinders 6 and 7 are the floating 3D and 2D bearings.

At this point it should also be mentioned that the three frame bodies 2, 3 and 4 are subject by a rolling frame frame part not shown here to form the present rolling frame 1.

The second exemplary embodiment of a rolling frame 101 shown in Figures 5 and 6 has substantially the same construction of the rolling frame 1 of the first exemplary embodiment illustrated with respect to Figures 1 to 4, so that with respect to this second exemplary modality only the changed construction components and of different configuration will be explained to avoid repetitions.

The rolling frame 101 also comprises three frame bodies 102, 103 and 104, these frame bodies 102, 103 and 104 being in active connection with each other by means of a force element 150, 151 and 152 acting between the frame bodies 102/103 and 103/104 and 104/102 in each case adjacent to each other; and specifically so that the frame bodies 102, 103 and 104 absorb the rolling forces and with a suitable configuration form a rolling frame unit without an additional rolling frame frame (not shown here) built around them.

By this it is possible to substantially simplify the shape of the rolling frame 101 in a further manner, so that for example a Extremely simple adjustment of cylinders 5, 6 and 7 when changing or reconverting cylinders to another 8A gauge.

In this second exemplary embodiment, the first force element 150 is formed by a threaded connection 153. A respective perforation 154 of the threaded connection 153 extends parallel to the axis 15 for insertion and rotation of the first cylinder 5, whereby the threaded element 155 itself is inserted into the first body 102 of the frame or is screwed through in a thread 156 through and successively in a blind hole thread 157 in the second frame body 103.

In this respect, the two frame bodies 102 and 103 are in direct contact with each other via the contact surfaces 160 and 161 (see FIG. 6). By this the requirement of additional constructive components forming a rolling frame frame is excluded, due to which the adjustment is further simplified by changing cylinders 5, 6 and 7.

The second and third force elements 151 and 152 are configured in each case by an articulated connection or respectively by a corresponding guide 165 and 166. Both frame bodies 104/103 and 104/102 can be mutually displaced in guide 165 and 166 respective.

In this regard, the first guide 165 of the two frame bodies 104 and 103 are made to each other by a first rotary joint 167 and the second guide 166 between the third frame body 104 and the first frame body 102 by means of a second articulation 168 rotating. Each of the joints 167 and 168 can be made to withstand great stresses by means of two side frame plate elements formed by the frame body 4 or respectively an articulated tongue element which are mounted rotatable in bearing in each case between the two frame plate elements . The articulated tongue elements are respectively formed by the frame body 102 and 103, the articulated tongue elements and the frame plate elements being connected to each other for rotary movement by means of a pin as pivot axis.

The guides 165 and 166 and the pivoting links 167 and 168 are furthermore housed in areas lacking in rolling force between the seats 4A and 3B and 4B and 2B of the bearing.

In particular by the bodies 102, 103 and 104 configured by this construction and its connection 153 with thread and articulated connections and guides 156 and 166 the Laminate frame 1 can be constructed very compact by virtue of which it is possible to do without a frame of rolling frame (not shown here) additional.

The rolling frame 101 can additionally be constructed even more compact, in particular smaller if the force elements 150, 151 and 152 are arranged radially to the outside and axially at the height of the cylinders 5, 6 and 7. This is valid in particularly if the respective force element 150, 151, 152 is axially disposed in the vicinity of a gauge base 170 (here symbolized only and emptily) of the cylinders 5, 6 and 7. The gauge base 170 is formulated by a region 171 with the deepest recess of the respective cylinder 5, 6, 7 and of the associated cylinder element 12, 13 and 14. In particular, it is possible to provide the respective force element 150, 151 and 152 in a sufficiently central manner.

The lamination frame 201 shown in FIGS. 7 and 8 as a third exemplary embodiment substantially has an identical structure as the two laminate frames 1 and 101 already described above. However, the rolling frame 201 differs in relation to its frame bodies 202, 203 and 204 in particular because instead of the articulated connections and guides 165 and 166 previously explained now only connections 253, 275 and 276 with thread are provided. All the threaded connections 253, 275 and 276 comprise as the force elements 250, 251 and 252 in each case a screw element 255 (symbolized here only in exemplary manner) which is screwed into respective threaded holes 254, so that the bodies 202, 203 and 204 of the frame are in active contact directly with one another in their respective pairs 277, 278 and 279 of contact surfaces. By this the rolling frame 201 is constructed particularly compact, so that work in connection with a roll adjustment is substantially simplified. The individual frame bodies 202, 203 and 204 are mounted for displacement of movement along a axis 202F, 203F and 204F of movement towards the rolling line 8 or away from the rolling line 8, whereby it is substantially simplified the manipulation of bodies 202, 203 and 204 of the individual chassis and thereby it is possible to carry out an accelerated change of cylinders. By virtue of the fact that all the other components and groups of components are identical to those described above, these are only provided with reference symbols that are identical to those of the preceding exemplary embodiments in relation to the rolling frame 1 and 101.

In the fourth exemplary embodiment shown in 9 to 11, the rolling frame 301 shown therein comprises a total of four frame bodies 380, 381, 382 and 383 which are fastened together by a frame 384 of the rolling frame. Additionally, the individual frame bodies 380 to 383 are in active contact by means of elements 385, 386, 387 and 388 of fastening parts of the rolling frame frame 384. That is, the first frame body 380 and the second frame body 381 are mutually supported and with the frame frame 384 by the first fastener member 385. In addition, the second frame body 381 bears against the third frame body 382 by a second fastener element 386. In addition, the third frame body 382 is supported by a third fastener element 387 in the fourth frame body 383. And between the first frame body 380 and the fourth frame body 383 acts to support the fourth fastener element 388.

With the help of the rolling frame frame 348 and the four fastening element elements 385, 386, 387 and 388 the individual frame bodies 380, 381, 382 and 383 are in total clamped together in the rolling frame 301 and mounted so that they can be moved by sliding, as shown by a comparison of figures 10 and 11, whereby a mounting of this type is particularly suitable for the exemplary embodiment shown in FIGS. 1 to 4. Contrary to the three exemplary embodiments explained in the foregoing, the rolling frame 301 is further characterized by two input shafts 309A and 309B, which likewise they are defined as elements of insert cylinders.

In this regard, the rolling frame 301 has two first cylinders 305 and a second cylinder 306 and a third cylinder 307, which in common form the caliber 308 of the rolling frame 301.

The two input shafts 9A and 9B rotate in each case around the insertion and rotation axes 315A and 315B, while a cylinder shaft 309 of the second cylinder 306 rotates about a second insertion and rotation axis 316 and a shaft 306. 310 of cylinder of third cylinder 307 about a third axis 307 of insertion and rotation.

The first frame body 380 configures two bearing seats 380A and 380B. Correspondingly, the second frame body 381 forms two bearing seats 381A and 381B, the third frame body 382 two bearing seats 382A and 382B as well as the fourth frame body 383 correspondingly two seats 383A and 383B of tread .

The bearing seats 380A and 380B of the first frame body 380 are made as floating bearings (not symbolized here) in the form of tapered roller bearings in an X arrangement.

The bearing seats 381A and 381B of the second frame body 381 are each configured as fixed bearings (not shown here). These fixed bearings comprise both a double-acting axial ball bearing and a double-row radial cylindrical roller bearing.

Both bearing seats 382A and 382B of the third frame body 382 are again realized as purely floating bearings, which in each case comprise tapered roller bearings arranged in X.

On the other hand, the two bearing seats 383A and 383B of the fourth frame body 383 are again configured as fixed bearings (here not explicitly symbolized). Also these fixed bearings of the fourth frame body 383 comprise in each case an axial double-acting ball bearing as well as two radial two-row cylindrical bearings.

The first input shaft 9A is correspondingly mounted in the first frame body 380 by means of a conical wheel 389 via the floating bearing of the first bearing seat 380A and in the second frame body 381 by means of a bushing 390 blind hole head by way of the fixed bearing of the first bearing seat 381A.

The second input shaft 9B on the other hand is mounted in bearing to the fourth frame body 383 by a bearing bush 391 via the fixed bearing of the first bearing seat 383A and on the other hand to the third frame body 382 by a conical wheel 392 header by way of the floating bearing of the second bearing seat 382B. By means of this, it is also possible in the rolling frame 301 of the fourth embodiment to achieve the advantages already explained several times with respect to the simplification of the roll adjustment.

The second cylinder 6 and the third cylinder 7 are mounted identically in the rolling frame 301, specifically in each case via a through bushing 326 and 327, as well as a conical wheel 323 and 324.

The exemplary embodiment shown in Figures 12 and 13 shows a first possible structure of a favorable rolling installation 1000 in which the previously described rolling frames 1, 101, 201 or 301 can be used and operated.

In this rolling installation 1000, each frame location 1001 is assigned a self-adjusting drive motor 1002 and a timing gear 1003 with two outputs (not shown here) in each case to a rolling frame 401 which is located in the frame location 1001 in a rolling position 1004. Rolling frames 401 are also made here as cassette elements that move. The drive motors 1002 rest on a foundation 1005 which also supports the frame locations 1001. The rolling frames 401 comprise in this exemplary embodiment in turn four cylinders (see, for example, figures 9 to 11) which form a gauge for a rolling product to be rolled. All the rolling frames 401 according to this embodiment have the same construction with the exception of the gauge diameters, which in this exemplary embodiment tapers at a laminating direction 1006 of laminate frame 401 to laminate frame 401, and which may otherwise change its gauge in other exemplary embodiments.

In this exemplary embodiment, the rolling frames 401 of the even-numbered frame locations 1001 are arranged on a rolling mill upright inclined by 22.5 ° to a rolling axis corresponding to the rolling direction 1006 relative to the horizontal within the laminating line 8 (see figures 1 to 11). Accordingly, the lamination frames 401 of the odd number frame locations 1001 are disposed in the rolling mill pillar displaced by -22.5 ° with respect to a rolling axis corresponding to the rolling direction 1006 with respect to the rolling stock. to the horizontal. Accordingly, a rolling frame 401 is displaced in each case by 45 ° about the rolling axis relative to the adjacent adjacent laminate frame 401.

The individual rolling frames 401 are in this exemplary embodiment in each case on a shifting shoe 1007 (see figure 13) guided with rollers. This special change device allows a change of rolling frame in a few minutes in a minimum of space.

The rolling frame change of the even-numbered rack locations 1001 is effected in the rolling direction 1006 from the right side of the rolling line 8. The change of rolling frame of rolling sites 1001 with number non is made in the rolling direction 17 from the left side of rolling line 8. On each side of the rolling mill 1000, on rails not symbolized that are supported by the foundation 1005, there is a shift carriage 1008 that moves to receive both the rolling frames 401 that are in operation until a change as well as the rolling frames 401 ready to go into operation. Likewise, on each side of the rolling mill there is for each rolling frame 401 a device 1009 for removing the rolling frame with a hydraulic extractor cylinder which in each case is supported on the base 1005. The change of the rolling frames 401 Individuals are possible without problems with the help of these rolling frame extraction devices 1009.

The rolling frames 401 which are in operation are thrown for the change with the cylinder of the device 1009 for removing the rolling frames from the rolling mill pillar or out of their frame location 1001 on the respective changing carriage 1008. , whereby on a change path 1010 they describe an arc, and from their inclined position of 22.5 ° and -22.5 ° at their rolling position 1004 they reach their horizontal position on the shift carriage 1008 at a position 1011 of change. After this the shift carriage 1008 moves along the rolling direction 1006 by a frame distance. Now the rolling frames 401 ready to be changed to a rolling position 1004 are opposite the opening of the rolling mill pillar and with its position 1001 of change against the frame location 1 and can be pushed with the cylinder of the frame removal device 1009. laminate on the frame location 1001 to the rolling position 1004 within the rolling mill pillar. Having reached the rolling frames 401 as an inclined position of 22.5 ° or -22.5 ° was moved on the shift path 1010 and brought to the rolling position 1004, for the transmission of the driving power the input clutches 1012 (see figure 13) automatically couples the drive motors 1002 to the rolling frames 401.

The automatic coupling of the input clutches 1012 is facilitated by the inclined position of the shift path 1010 of 22.5 ° and -22.5 ° in the region of the rolling position 1011, by virtue of which forces are not required for the coupling process. additional by virtue of the force of gravity. Therefore, according to this the rolling frame removal device 1009 requires only a fraction of the driving power to move the rolling frames 401 to the rolling positions 1011 to remove the rolling frames 401 after the rolling. operation. The inclined shift path 1010 also gives a high operational safety during the rolling by virtue of which the rolling frames 401 rest against the respective frame location 1001 by virtue of their own weight and are placed in this way. As to this, it is optionally possible to omit additional insurance for the positioning of the rolling frames 401, as in particular in this exemplary embodiment.

The lamination frames 401 that are removed from the rolling installation 1000, which are now appropriately displaced are mounted on the shift carriage 1008 can be taken from the shift carriage 1008 with a crane after the rolling operation is started again, to be fed to another use or replaced by new rolling frames 401, 1, 101, 201 or 301. It is also possible to carry out other activities there, such as immediate maintenance or the like. The shift shoes 1007 remain in this embodiment example preferably on the shift carriage 1008 when the rolling frames 401 are taken from the shift carriage 1008. By virtue of the two positions 1011, 1011A of change on the common change carriage 1008 it is clear that the assembly time and consequently the dead time of the rolling installation 1001 are reduced to a minimum, since the actual transportation of the 401 racks from rolling to the rolling plant and outside the rolling plant is decoupled from the actual assembly.

The alternating arrangement of the rolling frames 401 along the rolling line 8 and along the rolling direction 1006 provides the additional advantage, as can be seen in Figure 12, that the rolling frames 401 are arranged offset from each other by 45 ° respectively relative to the rolling axis. By this, a burr that possibly occurs when the laminate se. it smooths as it passes through the next rolling frame 401, since the edges which collide with each other of the rolls used in each rolling frame 401 are in another position at each step of a rolling frame 401, specifically moved by Four. Five.

In the sectional view of the rolling installation 1000 according to FIG. 13, the arrangement of an even-numbered frame location 1001 with an angle of 22.5 ° relative to the horizontal and of the shifting device arranged to the right with respect to the rolling direction 1006. For the non-number frame sites 1001, the specular arrangement is valid, wherein in each case a drive 1002 of an even-numbered frame location 1001 is disposed below the change position 1011 of a location number 1001 of number non. The alternating arrangement of the drives 1002 also allows the use of more powerful drives by virtue of which there is now more free space for an individual drive along the rolling direction 1006, and it is possible to use drives with about twice as much and consequently greater torque.

The alternating arrangement of the respective shifting paths 1010 further motivates in this embodiment directly that between the rolling frames 401 at the individual shifting positions 1011 and 1011A there is sufficient space for an additional rolling frame 401 at one of the positions 1011 and 1011A of change, by virtue of which at this height the frame location 1001 provided therein is either equipped or reconverted from the other side. Accordingly, by moving the shift carriage 1008 by a rolling frame width it is possible to provide a corresponding set of new rolling frames 401.
