Korgan Construction Company "Worcester, Mass.? United States Device for the axial adjustment of rollers.

The invention relates to a device for axial adjustment of palaces, the \ is located between this and the \ 7alzenzapfen or the chock extending screws essentially of an secured to the roller stand TJ-shaped yoke and.

Calibrated rolls for rolling profiles require a Device for the axial adjustment of the rollers, if necessary by correcting the roller position in the horizontal ensure that complementary calibres are exactly opposite one another. Such devices are in great numbers known; so in the German patent specification 70S 935 is one Axial support for rotating bodies described in the s: .ch between the bearing journal of a cylindrical rotating body and an axially supported hollow pin a pendulum support asur absorption of the axial compressive force is located. However, the known device is only geriohteter on one side for receiving Pressure forces, but not suitable for absorbing axial adjustments of rollers or the like ..

From the Swiss patent 365 685, however, an axial i management of rollers known, in which one between Y / Alzenapfen and bearing arranged connecting rod both axial Absorbs tensile as well as axial compressive forces. An axial adjustment of the rollers, however, is possible with this known device not possible · This is only made possible by a device known from US Pat. No. 2,665,959 in which wiping the roll neck and one on the roll stand

fixed abutment a sleeve-like chock extends, via the when two tension bolts or one Pressure screw the roller can be adjusted axially. A similar device is disclosed in U.S. Patent 2,651,956; known and consists of a U "-shaped yoke attached to the roll stand, in which an axially movable bearing housing is guided between adjusting screws 73 for the ¥ al cant. :

In the known from the ÜS Patent 2,175,783 device parallelogram act in pairs on the roll chocks ^r, v / hile the device according to the US-Patentschrift2173 623 / alzen stator housing has mounted on Y, ·. in which adjusting screws acting on the opposite end faces of the 'rollers are guided for the axial adjustment of the folds. · '., -:

All known devices, as far as they relate to the axial adjustment of rollers, allow a more or less axial adjustment of the Y / cylinders, but in no case is there the possibility of the vertical adjustment of the Y / cylinders without actuating the adjustment mechanism change, as in all cases, the chocks with the Ilechanis- \ mechanism for the axial roller adjustment form a rigid unit. A further part of the known devices results. also from the rigid connection between the chocks and the associated adjustment mechanism, which eliminates an adaptation of the position of the chocks or aluminum pegs to the roll deflection that inevitably occurs during rolling; Since, in the known devices, after the axial adjustment, the chocks always remain in their position in relation to the stator, the bearings are subject to deflection due to the deflection of the valley. Rollers are extremely exposed to stress, which leads to premature wear. A

Change of the vertical position is in the known devices also only possible if the rigid connection between the roller stand and the adjustment mechanism has been released beforehand has been.

The object underlying the invention is to eliminate the disadvantages of the known devices mentioned and in particular to create a device that allows an exial adjustment of the rollers against each other and at the same time, independently of this, the vertical adjustment of the rollers as well as a slight rotation of the chocks which frequently occurs during the rolling operation permitted in the vertical. According to the invention, this object is achieved in such a way that the multi-directional joint consists of a steering member known per se with two ball heads which are each connected to threaded actuators in their direction of adjustment. The ball heads can be arranged in a distance adjustable and fixable on a common handlebars and the steering link can consist of a clamping cylinder sleeve, in the two ends of which the ball heads, each provided with threaded studs protruding from the sleeve, are placed on the end faces of a spacer tube. A bearing sleeve can be screwed into a threaded piece of the bridge anchor, between the bearing plates of which one ball head of the link rod is mounted, the other ball head of which rests between the bearing plates of a bearing sleeve that sits in a hood firmly connected to the chock backs two parallel carrying vertical plates having opposed at their inner sides hats, whose width corresponds to the thickness of a flange located at the Lagernuffe whose outer "csser in the do a calibration? the.

The two vertical plates can be connected to one another at their lower narrow sides by a cross bar in which there is a locking screw. The flange can have two parallel sides, the distance between which corresponds approximately to the distance between the plates. On one side of the \ narrow side of the flange, a stop can be placed. The bearing plates with the balls located between them in the bearing sleeves can be pressed against corresponding abutments without play by means of threaded washers. A spindle can be arranged in a thread of the bridge nozzle, the end of which, designed as a spherical head, free of charge, is mounted in the axially divided cylindrical sleeve between a bearing plate and a pan-shaped recess of a cylindrical spacer, between the other pan-shaped recess and a second bearing plate a ball is mounted which is attached to the end of a threaded bolt seated in a hood. At the free end of the threaded bolt a square nut can be attached by means of a pin, which sits in a chamber between claw-shaped bumps on the hood. A locking nut can sit on the threaded bolt outside the hood or its claws. The flange of a bearing sleeve can be located between the part-circular grooves in the claw-shaped brackets of the hood, in which a ball sitting on a threaded bolt is mounted between the bearing plates Flange lies in a circular opening of the yoke. Se balls with the associated bearing plates can each be held in the corresponding bearing sleeves without play by means of a threaded cap. Finally, an ilutter can sit on the threaded bolt on either side of each ball.

On the outside of the chock 6 sits a hood 48 fastened with screws 50. It has two vertical plates 52 and 54 with grooves 56 and 58. Between the plates 52 and 54 there is a wide bearing sleeve 64 with a part-circular flange 66, which is at 68 and 70 (Figure 4) is cut off. In the position shown in FIG. 4, the part-circular planes 66 rest in the grooves 56 and 58 and prevent axial movement of the bearing sleeve 64 with respect to the hood 48 the position according to Figure _5f , the flange 66 are rotated out of the grooves 56 and 58 so that the bearing sleeve 64 can be removed from the hood 48. In order to limit the rotation of the bearing sleeve 64 to 90 ° in each direction, it has a stop 71 'which strikes either the plate 52 or 54 during the rotary movement.

In one extending between plates 52 and 54 Cross bar 60 is located, a locking screw 72 for plaguing and support of the bearing sleeve 64 · In addition, the bearing sleeve 64 is connected to the Hood 48 locked.

The axial adjustment of the chock 6 takes place in such a way that "first the locking nuts 42 are loosened, a tool is inserted into the hexagonal opening 46 and the bearing" sleeve 38 is then rotated in one or the other direction. "After loosening from the yoke 28, the chock becomes 6 moved to the left via the dumbbell-shaped connecting piece 75, for example, if the bearing sleeve 38 is screwed inward, the chock 6 is pressed to the right by the connecting piece 75 (FIG. 3). Simultaneously with chock 6, the top roller also moves 16 "since the chock 6 is fixed in relation to the bearing sleeve 88 by conventional axial bearings between the chock and the bushing".

The chock 6 is freely movable on the inner surfaces 93ι ί 94 of the upright window and can therefore be raised or lowered or axially displaced in its vertical plane can also be rotated around a horizontal axis »while, due to the sliding fit of the installation piece in the stud window, a Movement in the direction of the stitch line is not possible "
