Abstract
Изобретение относитс к обработке металлов давлением и может быть использовано в машиностроении при выт жке пр моугольных в плане деталей. Цель изобретени - повышение качества выт гиваемых деталей и экономи металла путем предотвращени гофрообразовани . В процессе выт жки осуществл ют дифференцированное тангенциальное раст жение фланцевой части заготовки. За счет дополнительного деформировани фланца заготовки ребрами 4 при перемещении фланца в полость матрицы возникают силы P, которые создают раст жение в тангенциальном направлении металла на пр молинейных участках заготовки (в зонах 1). За счет раст жени фланца в зонах 1 величина сжимающих тангенциальных напр жений уменьшаетс , вследствие чего предотвращаютс потер устойчивости и образование гофр в этих зонах. 5 ил.The invention relates to the processing of metals by pressure and can be used in mechanical engineering when drawing rectangular parts in plan. The purpose of the invention is to improve the quality of the parts being pulled out and to save metal by preventing the formation of corrugations. In the course of drawing, differentiated tangential stretching of the flange part of the workpiece is carried out. Due to the additional deformation of the flange of the workpiece by ribs 4 when the flange moves into the cavity of the matrix, forces P arise, which create stretching in the tangential direction of the metal on the straight sections of the workpiece (in zones 1). By expanding the flange in zones 1, the magnitude of the compressive tangential stresses is reduced, resulting in the loss of stability and the formation of bumps in these zones. 5 il.
