Abstract

Изобретение относитс к обработке металлов давлением, в частности к штампам дл обработки листового материала. Цель изобретени - повышение надежности работы штампа. Штамп содержит нижнюю плиту 1 с матрицей 2 и со съемником 3 и верхнюю плиту 13 с пуансоном (П) 17 дл пробивки и П дл образовани элементов подъема материала (М) 26 над матрицей 2. В съемнике 3 установлены прижимы в виде шариков 12. При рабочем ходе штампа П 17 производит пробивку, а П дл образовани элементов подъема надрезают и отгибают зычки 27. При продвижении М 26 элементы подъема материала поднимают его над зеркалом матрицы 2, а прижимы 12 дополнительно искривл ют. При установке М 26 на следующей позиции элементы 27 попадают в предусмотренные дл этого на матрице 2 канавки и не мешают обработке. 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. The stamp contains a lower plate 1 with a die 2 and with a puller 3 and an upper plate 13 with a punch (P) 17 for punching and P to form lifting elements (M) 26 above the die 2. In the puller 3, clamps in the form of balls 12 are installed. The working stroke of the punch P 17 produces punching, and P to form the lifting elements, the tongues 27 are bent and bent down. As M 26 moves, the lifting elements of the material lift it above the mirror of the matrix 2, and the clamps 12 are bent. When installing M 26 at the next position, the elements 27 fall into the grooves provided for this on the matrix 2 and do not interfere with the processing. 3 hp f-ly, 6 ill.

Claims

Claim

1. A stamp of sequential action for processing sheet material, containing punches for cutting on a movable plate, on a fixed plate - matrices corresponding to them, a single stop and a puller, and also containing means for receiving material lifting elements above the matrix mirror, made in the form of symmetrically arranged relative to the axis feeding pairs of tools, each of which includes a punch movable relative to a fixed plate, and a matrix made in this plate coaxially with the punch, and recesses for placement . elements and means of forming elements. for the step fixation of the processed material, characterized in that, in order to increase the reliability of the work, it is equipped with means for pressing material sections adjacent to the edges located in the puller on both sides of the feed axis, the material and at a distance from it, exceeding the distance from it of tools for receiving lifting elements.

2. The stamp on π. 1, characterized in that each clamp means is made in the form of a spring ball.

3. The stamp on π. 1, characterized in that the punch for receiving the lifting element is made with a bevel on the working end, equipped with a cutting edge and forming an acute angle with the matrix mirror facing its apex in the material supply direction, part of the edge of the matrix hole is made cutting, and on the non-cutting edge of the matrix hole made a bevel directed similarly to the bevel of the punch.

5 4. The stamp according to π. 1, characterized in that on the mutually facing edges of the holes of the matrix for cutting and puller bevels are made.
