Abstract
1,172,699. Corrugating sheet metal. A.P.V. CO. Ltd. 7 Nov., 1967 [16 Nov., 1966], No. 51433/66. Heading B3E. ' A method of pressing a metal sheet to shape comprises placing the sheet between press tools and progressively moving one of the tools into metal forming engagement with the sheet starting at one end of a zone to be pressed and progressing along the zone, wherein one of the tools is formed as a pack of relatively movable laminae in face-to-face engagement, the laminae being moved successively into engagement with the metal by applying pressure to an edge remote from the sheet. An apparatus for carrying out the method comprises a lower tool block 26 having a corrugated working surface 27 and an upper tool block 28 in which are mounted laminae 29, the lower edges of which co-operate to define a working surface when their upper edges are flush with the top of the block 28. The lower block 26 is fitted with rollers 22 which run on a machine bed 1 and along which the toolblocks are pulled by a chain 23 which passes round a guide pulley 24 and a driven pulley 25. The laminae 29 are pressed down sequentially as they pass under a first roller 6 and a second roller 7. The first roller has a small flange at each end, the flanges engaging the top edges of the block 28 and pressing it towards the lower tool block 26 so that the edges of the sheet being pressed are held between the two blocks and prevented from wrinkling. The second roller 7 has a plain cylindrical surface. The top edges of the laminae 29 are angled downwardly at 10 degrees in the direction of travel of the blocks to provide gradual engagement with the rollers. The two rollers are mounted between brackets 5 attached to slide blocks 4 which run on a frame 3. At each side of the frame 3 a chain 15 runs over a guide pulley 10 and a pulley 14 and is dead-ended on the frame. The pulley 14 is mounted on the piston-rod 12 of an hydraulic cylinder 11 which is biased to the extended position. In a modification a flat spring steel plate is interposed between the rollers and the upper edges of the laminae.
