Abstract

Изобретение относитс к обработке металлов давлением, в частности к штампам дл обработки листового материала. Цель изобретени - повышение надежности работы штампа и улучшение условий эксплуатации. Штамп содержит нижнюю плиту 1 с матрицей 3 и ловителем (Л) 2. Л 2 имеет привод в виде пневмоцилиндра 5 с поршнем 6 и штоком 7 и установлен в шариковом сепараторе 4. Со штоком 7 св зан ступенчатый стержень 8 и между ним и Л 2 установлена пружина 9. На той же плите 1 установлена устройство контрол (УК) положени штампуемого материала (М) 29 в виде стержн с кольцевой канавкой на боковой поверхности. Стержень имеет индивидуальный пневмопривод. Поверхность кольцевой канавки контактирует с шариком. УК включает также переключатель. На верхней плите установлен толкатель 16 соосно с Л 2 и толкатель - соосно со стержнем УК. При установке М 29 на рабочей позиции Л 2 перемещаетс от пневмоцилиндра 5 и входит в отверстие М 29, а стержень УК под действием своего пневмопривода входит в другое отверстие М 29. При рабочем ходе толкатели опускают Л 2 и стержень УК. При отклонении шага подачи стержень УК не попадает в отверстие М 29, шарик выдавливаетс из кольцевой канавки и через переключатель отключает пресс. 3 з.п. ф-лы, 6 ил.The invention relates to the processing of metals by pressure, in particular to dies for processing sheet material. The purpose of the invention is to increase the reliability of the stamp and improve operating conditions. The stamp contains the bottom plate 1 with the matrix 3 and the safety gear (L) 2. The L 2 has a drive in the form of a pneumatic cylinder 5 with a piston 6 and a rod 7 and is installed in a ball separator 4. A stepped rod 8 is connected with the rod 7 and between it and L 2 A spring 9 is installed. On the same plate 1, a device for controlling the position of the material being stamped (M) 29 is installed in the form of a rod with an annular groove on the side surface. The rod has an individual pneumatic actuator. The surface of the annular groove is in contact with the ball. The CC also includes a switch. On the top plate, the pusher 16 is mounted coaxially with L 2 and the pusher is coaxially with the CC core. When M 29 is installed at the working position L 2, it moves from the pneumatic cylinder 5 and enters the opening M 29, and the control rod under the action of its pneumatic actuator enters another opening M 29. During the working stroke, the pushers lower L 2 and the control rod. When the feed pitch is deflected, the control rod does not enter the hole M 29, the ball is squeezed out of the ring groove and switches off the press through the switch. 3 hp f-ly, 6 ill.
