RU2220806C1 - Mill for rolling belts of decorative articles with convex-concave surface of pattern - Google Patents

Abstract

FIELD: plastic metal working. SUBSTANCE: mill for rolling thin belts includes working stand, rolling rolls, drive unit. In order to make belts of decorative articles with convex-concave relief of pattern, one rolling roll has rubber bandage; other rolling roll has pattern with convex-concave relief. Total height of convex portions and depth of recesses is less than thickness of rubber bandage. EFFECT: enlarged manufacturing and technical possibilities of mill for rolling different belts with convex-concave pattern on their surface with use of the same set of rolls, enhanced efficiency, simplified maintenance of mill. 1 dwg

Description

 The invention relates to the processing of metals by pressure, in particular to equipment for the longitudinal rolling of tapes of art products with a convex-concave surface of the figure. The objective of the invention is the expansion of technological and technical capabilities of the rolling mill by ensuring the rolling of various strips with a convex-concave pattern on the surface on the same set of rolls, increasing productivity and facilitating maintenance of the mill. In frame 1, on pillows 2 and 3, a non-driven work roll 5 (pv 5) with a rubber band 6 (for example, rubber brands: 3826, 4004, 56), the thickness of which exceeds the total height of the protrusions and the depth of the depressions of the figure. The pattern on the surface of the drive roll 4 (pv 4) is made convex-concave. The gap between the rollers is regulated by the pressure device 9 and the springs 10. Changing the gap between the pv 5 and pv 4 provides a convex-concave surface of the figure.

 The drawing shows a mill for rolling ribbons with a convex-concave artistic pattern, General view.

 In the frame openings on pillows 2 and 3, non-drive rolls 5 with a rubber band 6 and a drive roll 4, respectively, are mounted on the surface of which a convex-concave pattern is made. The roll cushions are pressed by pressure screws 9 and springs 10.

 Between the non-driven bandaged rubber 6 of the roll 5 and the work roll 4 with a convex-concave pattern, tape 8 is placed. When rolling, a convex-concave art pattern is formed on the surface of the tape.

 The mill works as follows. According to the drawing, the blank - tape 8 is fed between the roll 5 with a rubber band 6 and the drive roll 4 with a convex-concave surface relief. Under the action of the rolling force transmitted through the rubber layer, an artistic convex-concave pattern is formed on the tape by deformation.

 Using the mill makes it possible to obtain different tapes on the same set of rolls with a convex-concave surface of the pattern by replacing the roll with a surface pattern, i.e. provides expansion of technological and technical capabilities of the rolling mill.
