Abstract

1533043 Shearing KOMBINAT UMFORMTECHNIK ERFURT VEB 26 Feb 1976 [7 March 1975] 07617/76 Heading B3W The end to be sheared from a billet is supported during shearing by a support shoe 16 on a slide 11, the slide being movable by the press drive and the support shoe 16 being movable relative to the slide by a separate drive. The connecting rod slide 4 of the press is connected to the slide 11 via a pressure member, 5 links 6a, 6b, bell crank levers 7a, 7b, seating in an upper cutter slide 9 at 8a, 8b, and rods 10a, 10b. The shoe 16 on a rack driven spindle 12 carries a stop 19 engageable with a stop 18 on the shear frame 1 to prevent the shoe rising above the top edge of the lower cutter. An adjustable stop 21 on the rack engages a stop 20 on the slide 11 to control the rack stroke in accordance with the cross-section to be cut. A hold down is provided. In operation, lowering of the connecting rod 3 is transmitted to the levers 7a, 7b which pivot on the slide 9 causing the rods 10 to raise the slide 11. The spindle 12 is also actuated to raise the shoe to hold the billet against the top cutter. Immediately the shearing is completed, springs 13a, 13b lower the slide.
