Abstract

812,683. Cutting and punching machines. HIRD, G. April 22, 1955 [Jan. 23, 1954], No. 2091/54. Classes 31 (1) and 31 (2). [Also in Groups XVI and XXII] Apparatus for feeding and working strip, e.g. plastic, comprises two units spaced along the strip and each having slidably interconnected bolsters one on each side of the strip, the bolsters being moved through opposed circular paths and carrying tools and grippers, for working and feeding the strip, the bolsters of the two units being driven at 180 degrees out of phase. A machine, Fig. 1, punches and shallow forms blanks from strip and shears the waste strip. The shearing and feeding unit 21 comprises bolsters 15<SP>1</SP> pivotally mounted on opposed oppositely rotating crankshafts having crank pins 14, and carrying shear blades 17<SP>1</SP>. Guide rods 16<SP>1</SP> pass through holes in the lower bolster and are secured in the upper bolster. Resiliently loaded feeding grippers 25 are secured to bolts 27 passing through the bolsters. The rate of feed and the lateral movement of the blades 17<SP>1</SP> is adjustable by means of variable eccentrics 24 between the crank pins 14<SP>1</SP> and the bolsters 151 or by making the crank pins 14<SP>1</SP> adjustable radially of the crankshafts. The grippers 25 are centred by work guides 28. The punching and forming unit 22 has bolsters 15<SP>11</SP> actuated and guided as described above. The upper bolster carries adjustably a tool support 29 secured by a grub screw 33 on the guide rod 16<SP>11</SP> and a spring-loaded stripper 30. The lower bolster 15<SP>11</SP> carries a resiliently mounted lower tool holder 31. In modifications, two feed units operate alternately. A number of press tools may be mounted in the same unit to perform successive operations at different work stations on the same strip.
