Abstract
Изобретение относитс к обработке металлов давлением, а именно к способам изготовлени створок петель, преимущественно ро льных. Цель изобретени - повышение качества петель. Штамп дл осуществлени способа содержит матрицу 2, предварительные упоры 8 и 9, посто нный выдвижной упор 10 и пуансон 13. На первом переходе полоса 4 подаетс до упора 8 и осуществл етс пробивка отверстий 3 и надрезка полосы. Затем полоса подаетс до упора 9. На этом переходе полоса 4 надрезаетс по продольной ступенчатой линии: вырубают выступ одной створки и примыкающие к нему продольные участки паза и выступа другой створки. При подаче полосы 4 до упора 10 срезаютс две другие стороны паза (режущими кромками С) и одновременно производитс последующий ступенчатый надрез полосы 4 и пробивка отверстий. 6 ил.The invention relates to the processing of metals by pressure, in particular to methods for producing hinge flaps, preferably rotary. The purpose of the invention is to improve the quality of the loops. The stamp for implementing the method comprises a die 2, pre-stops 8 and 9, a permanent pull-out stop 10 and a punch 13. At the first crossing, the strip 4 is fed up to the stop 8 and the holes 3 are punched and the strip is cut. Then the strip is fed up to the stop 9. At this junction, strip 4 is incised along a longitudinal stepped line: the protrusion of one flap and the longitudinal portions of the groove and protrusion of the other flap are cut down. When the strip 4 is fed up to the stop 10, the other two sides of the groove are cut off (cutting edges C), and a subsequent stepped notch of the strip 4 and the punching of the holes are simultaneously made. 6 Il.
