Abstract

The invention relates to the processing of metals by pressure and can be used for the manufacture of various pasbeMOBv used in the switching technology of communication. The purpose of the invention is to increase the production capacity of the method by combining operations and expanding the technological capabilities of the stamp used to perform the finishing operations of the method. When separating the legs 5 of the contact element installed in the insulator 4 from the carrier tape 7 (waste), at the same time as its separation, its end is molded and calibrated by the protrusions 23 and 24 of the punches 15 and 19, respectively. Combining the cutting and shaping operations, as well as performing the calibration operation with the same tool, improves the performance of the method. At the same time, the technological capabilities of the stamp, which allows the same tool to carry out operations of cutting, shaping and calibration, are expanded. 2 sec. f-ly, 9 ill.

Claims (2)

Claim 1. A method of manufacturing contact elements, including cutting down the reamer of the contact elements from the tape blank to form the leads of the contact elements without separating them from the workpiece, forming the working part of the contact elements, cutting off the contact groups, installing the latter in the insulator and separating the conclusions of the contact elements of the contact groups from the workpiece, characterized in that, in order to increase productivity by combining operations, simultaneously with the separation of the conclusions of the contact elements from the workpiece they are molded, and then calibrated, and the ends of the terminals of the contact elements are molded and calibrated by the surfaces of the same tools that are used to cut them. 2. A combined action stamp for machining parts, primarily terminals of contact elements, comprising a top part with a punch and a spring-loaded clamp and a lower part with a die and a spring-loaded punch, characterized in that, in order to expand technological capabilities, the spring-loaded clamp is placed directly above the matrix of the matrix, the cutting edges of the matrix and punches are located on their working ends so that in the projection on a horizontal plane coinciding with the mirror of the matrix, they form equidistant scrap lines in the form of alternating triangular protrusions and depressions, while the working ends of the punch placed in the upper part of the stamp are located above 10 triangular depressions in the matrix formed by its cutting edges and are inclined to the mirror plane of the matrix in the direction of the vertices of its depressions by an acute angle, and the working ends of the punch placed in the lower part of the stamp are located in the corresponding grooves of the matrix and are made mirrored to the working ends of the punch placed in the upper part of the stamp relative to the mirror of the matrix. 1 · 1: 1 J 1 1 m Ί r ⁿ - < about ί- FIG. 9
