Abstract
Изобретение относитс к обработке металлов давлением, в частности к оснастке дл пробивки-вырубки листового материала. Цель изобретени - повышение стойкости матрицы за счет увеличени допустимого количества переточек. Матрица 1 имеет рабочее отверстие, ограниченное поверхностью 5. Последн выполнена с переменным углом наклона к оси отверсти . Этот угол уменьшаетс в направлении от зеркала 3 к опорному торцу 2. Поверхность 5 может быть образована отрезком плавной кривой или ломаной линией. При вырубке (пробивке) пуансон 6 проталкивает отделенный кусок материала в отверстие матрицы 1. При переточке последней сохран етс эквидистантность вновь полученной режущей кромки первоначальной. 2 з.п.ф-лы, 5 ил.The invention relates to the processing of metals by pressure, in particular to the tooling for punching-out of sheet material. The purpose of the invention is to increase the durability of the matrix by increasing the allowable number of refluxes. The matrix 1 has a working hole bounded by the surface 5. The latter is made with a variable angle of inclination to the axis of the hole. This angle decreases in the direction from mirror 3 to the supporting end 2. Surface 5 may be formed by a segment with a smooth curve or a broken line. When cutting (punching), the punch 6 pushes the separated piece of material into the hole of the matrix 1. When the last is repainted, the equidistantness of the newly received cutting edge of the original is maintained. 2 hp ff, 5 ill.
