Definitions

  • the invention relates to closure element for a machine frame of a roller press, which sits as a cap end on a frame member.
  • An essential criterion for the economy of the frame construction is the duration with which the frame can be dismantled, so that a change of the rolls according to their scheduled wear is simple and inexpensive to carry out.
  • a machine frame is taught in tuning fork shape, which receives a self-contained force system of roller presses and Anpresshydraulik.
  • This machine frame is closed to each side of the machine frame with an open-held frame section as a closure, which is thrown over the legs of the tuning fork-shaped machine frame, this frame section sits as a closure in a bay of the legs of the tuning fork-shaped machine frame and forming against the bay, harn features cup-shaped extensions in the legs of the tuning fork-shaped machine frame.
  • This frame section as a closure is itself U-shaped and rests on the upper leg of a machine frame side of the tuning fork-shaped machine frame and can accommodate high, horizontally directed forces of the rollers, the forces of the rollers on stub shafts, which sit in a bearing block, on the bearing block be transferred to the frame section as a closure.
  • the object of the invention is therefore to provide a closure for a tuning fork-shaped machine frame for a roller press, which does not become wedged.
  • the object of the invention is achieved in that the closure element has means by which a pendulum movement on the frame member is possible.
  • the closure element perform a pendulum motion in use.
  • the closure element is thus not firmly connected to the frame, but it is provided to store the closure element floating.
  • "floating mounting” is understood to mean that the closure element has more than one degree of freedom of movement in use, ie, it can move in more than one degree of freedom in the machine frame, thereby ensuring that the closure element thus aligns under load in that it does not become wedged but conforms to corresponding abutments with all abutment surfaces and thus can absorb the maximum design-related force, without the closure element becoming wedged on the machine frame due to undesired placement and thus undesirably becoming firm there.
  • the invention will be explained in more detail with reference to the following figures.
  • FIG. 1 shows a machine frame according to patent application
  • FIG. 2 detail of the closure element according to the invention, highlighted in FIG. 1,
  • a machine frame 10 is shown, which is described in detail in patent application DE102010015374.5 and as an essential element two tuning fork-shaped frame components 1 1 and 12, which are open in this illustration to the rear.
  • the tuning fork-shaped frame components 1 1 and 12 are approximately rectangular frame, which give the entire machine frame 10, the necessary torsional stability.
  • two closure elements 21 and 22 are placed from above on the tuning fork-shaped frame components 1 1 and 12.
  • These sealing elements have a U-shape and surround with their legs in each case one leg of the tuning fork-shaped compassiond beauteils.
  • closure elements 21 and 22 engage in bays of the tuning fork-shaped frame components 1 1 and 12 and are based on horizontal loading by located within the tuning fork-shaped frame components 1 1 roller bearing against urn merkopfförm-ended end pieces 23 and 24 of the tuning fork-shaped frame components 1 1.
  • these closure elements 21 and 22 are not fixedly connected to the tuning fork-shaped frame components 1 1, but are floatingly mounted on these.
  • the floating is achieved in each case by a displaceable bearing 30, which are arranged on the inner side of the connecting piece of the two legs of the U-shaped closure elements 21 and 22 and which there have a ball joint 31, which is shown in Figure 3, and a sliding plate 32nd which is also shown in FIG.
  • the closure element 21 and 22 By sliding plate 32, the closure element 21 and 22 is freely supported in two degrees of translation A and B, wherein the ball joint 31 gives the closure element two rotational degrees of freedom C and D.
  • the closure elements 21 and 22 at the moment in which they lean against the hammer-head-shaped ends 13 and 14 of the tuning fork-shaped frame components 1 1 occupy an almost arbitrary position and fall into the position which by the contact points of urn merkopfförm igen end pieces 13 and 14 of the tuning fork-shaped frame components 1 1 are given.
  • the floating mounted closure elements 21 and 22 allow on the one hand a quick opening of the tuning fork-shaped frame components 1 1 and 12 to change the rollers contained therein, which must be replaced or refurbished after a predetermined time due to wear, on the other hand allow the fast-opening closure elements 21 and 22 a always optimal contact with the serving as an abutment urn merkopfförm end pieces 13 and 14 of the tuning fork-shaped frame components 1 1 and 12.
  • the securing bolts 40 may each have a split pin, by means of which the securing bolts 40 are secured in the closure element 21 and 22 or also each have a thread with which the securing bolts 40 are secured in the closure elements 21 and 22.
  • the locking pins 40 have a larger diameter than the respective, not shown here threaded head. This protects the closure element 21 and 22 against the fact that they are pulled by over tightening on the corresponding, tuning fork-shaped frame member 1 1 and 12 together and can therefore wedge.
  • closure elements 21 and 22 is supported by means of a needle bearing with two rotational degrees of freedom.

Abstract

L'invention concerne un élément de fermeture pour un châssis de presse à rouleaux, l'extrémité de cet élément de fermeture reposant, en tant qu'élément de recouvrement, sur l'extrémité d'un élément de châssis. Selon l'invention, l'élément de fermeture présente un moyen permettant un mouvement pendulaire sur l'élément châssis. Cela permet d'obtenir un élément de fermeture à montage flottant et donc un démontage très rapide pour un changement aisé des rouleaux. On obtient ainsi une installation optimale des éléments de fermeture sur des extrémités correspondantes du châssis.
