SU1349809A1 - Stand for rolling a strip - Google Patents

Abstract

The invention relates to the field of metal forming and can be used in workshops for cold rolling of strips, mainly thin strips. The purpose of the invention is to expand the range of rolled strips by increasing the crimping capacity of the stand and reducing the minimum roll out thickness, as well as improving the quality of the rolled strip by increasing the rigidity of the deforming system. The metal is rolled between the cylindrical surface of the prismatic element 7 and the work roll 1. The cylindrical part of the stationary element may have a different radius. The prism-like element is easily fixed, has greater strength than a roller of a similar radius. With decreasing deforming radius, rolling forces are reduced. Deformed The core of the stationary element can be fused or sprayed with wear-resistant hard material. 4 il. from (L 00 4 from 00 about with

The invention relates to the production of metals by pressure and can be used in workshops of cold .. stripes, mostly jieHTH,

The purpose of the invention :) is to expand the cciv tamament of rolled strips of ways to increase the crimping ability of the cage and reduce the minimum roll out thickness, and to improve the quality of the rolled strip by increasing the rigidity of the cephoropsy system,

Fig. 1 is a schematic representation of the following: a roll stand for rolling a strip, an incision section; in Fig. 2, a fixed edema with P. POSKOM lateral faces, general view; na - te, with convex lateral surfaces on figd - the same, with concave outcrops.

The cage for rolling the strip contains a driving worker for two 2 rows of racks with cushions 3, mounted and in the lower part of the frame 4, the backup roll 2 is equipped with a device 5. A tapered guide groove 6 of a prism-like fixed deformer is made in the crossbar of the bed 4 the element 7 with a cylindrical deforming surface 8; Axial displacements (along the barrel, wapka 1) ke / P (additional deforming element:; estgga 7

The cage works in the following manner. The Motionless Deforming Element: - 7 is inserted into the guide rail 6 of the crossbar of ethanica 4 so that the nx: the distorted surface 8 faces the pa6o4ei-rv roll 1 ,, then this element d You should :. clamps. With the help of pressing the I1 device 5, the required initial gap (or pressure) between the cylindrical deforming is established: the surface of the prism-like base of the element 7 and the working roll 1, the strip and the std-from; t rolling it. To replace the fixed deforming element 7, raise the lock and
