Abstract

The invention relates to the processing of metals by pressure, in particular to dies for bending V-shaped products, and allows for improving the quality of products. The stamp comprises bending dies in the form of rotary sections with supporting cylindrical surfaces. On the mirror of the matrix there is a groove for installing the workpiece, the bottom of which is recessed relative to the plane of the axes of rotation of the sections. The axes of rotation of the sections are located one relative to another at a distance less than the diameter of the supporting cylindrical surface. The workpiece installed in the groove does not move relative to the half-matrix while bending. The lack of slip of the workpiece prevents its damage and the wear of the die.

  1. BD 41 The invention relates to the processing of metals by pressure, in particular to tooling for cold forming, and to be used in the bending of blanks of sheet, round section and pipes. The purpose of the invention is to improve the quality of bending by eliminating the connection: folding out the bent shelves of the workpiece on the working surfaces of the matrix 1: 1; s and simplifying the stamp design. FIG. 1 presented at the initial moment are flexible; in fig. 2 the same, at the final moment are flexible. The stamp contains the location of the housing 1, a bending matrix with working surfaces 2 on the rotary sections 3 having a supporting cylindrical surface 4, and a punch 5. IIipH this on the matrix mirror made the groove of the workpiece installation, the axes of rotation are located one relative to another at a distance a reference diameter of the cylindrical surface, and the working surfaces of the matrix are placed on the bottom of the groove. The arrangement of the axes of rotation of the sodium sections 3 is calculated by the formula the distance from the centerline where ohm and matrix to the axis of rotation of the sections; - distance from the axis of rotation. sections to the core axis; - half the angle of the working part of the punch; - the gap between the punch and the die, equal to the thickness of the workpiece; -radius punch. 642 The stamp works as follows. Workpiece p6mep1; ayut between, clamps. In the interaction: the punch with the workpiece and the workpiece with the matrix sections, the latter are rotated around the point O and the straight section of the workpiece, starting from the point K, together with the sections of the matrix is rotated by angle. In this case, in the radius part, the workpiece departs from the die and the workpiece does not slide on the working surfaces. The fixation of the workpiece takes place during the whole process of bending, which makes it possible to improve the surface quality of the part and simplify the design of the die and thereby reduce the cost of its manufacture. DETAILED DESCRIPTION A stamp for bending V-shaped articles from piece blanks, comprising a punch and a bending matrix placed in the base housing with working surfaces on the rotary sections, having a supporting cylindrical surface, the axes of which are symmetrically located relatively to the punch parallel to its bending rib, so that, in order to improve the quality by eliminating the sliding of the shelves of the workpiece along the working surfaces of the matrix, a groove for the installation of the workpiece is made on the mirror of the matrix, a part of which is recessed relative to the plane of the axes of rotation of the sections, the axes of rotation of the sections are located one relative to another at a distance smaller than the diameter of the supporting cylindrical surface, and working surfaces) At the Atritz1l are located on the bottom floor paea.1
