Abstract

The invention provides a torsion die for machining a copper bar. The torsion die comprises an upper die base, a lower die base, a guide column, a positioning plate, a rotating block, a lower pressing block, an upper ejecting block and a push-back rod, wherein the rotating block is rotationally arranged on the lower die base, a concave cavity for twisting the copper bar is formed in the rotating block, and an inclined plane notch and a cylindrical convex block are arranged on the rotating block; the upper end of the lower pressing block is fixedly connected with the upper die base, and the lower end of the lower pressing block is integrally connected with an inclined plane contact part and a plane contact part; the upper ejecting block is arranged on the lower die base in a sliding mode; and the push-back rod pushes the rotating block to reset in the axial direction of the rotating block. According to the torsion die, the copper bar is punched through a punching needle, the inclined plane contact part is in contact with the inclined plane notch firstly, the rotating block is pushed to move in the axial direction of the rotating block, the edge of the punched copper bar enters the concave cavity, then the plane contact part is in contact with the cylindrical convex block, the rotating block is pushed to rotate, the copper bar is twisted, the push-back rod pushes the rotating block to reset in the axial direction of the rotating block, and then the upper ejecting block moves upwards to push the cylindrical convex block to enable the rotating block to rotate reversely.

Description

technical field [0001] The invention relates to the technical field of copper bar processing, in particular to a torsion mold for processing copper bars. Background technique [0002] When processing the copper bar, it is necessary to twist the edge of the copper bar after punching. [0003] Most of the existing processing methods are first cut by a mold, and then twisted by a lathe. The processing technology is complicated and not suitable for popularization and use. [0004] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Contents of the invention [0005] The object of the present invention is to provide a torsional mold for processing copper bars that can effectively solve the above technical problems. [0006] For reaching the purpose of the present invention, adopt following technical scheme: [0007] A torsion die for processing copper bars, comprising: [0008] Upper die base: connected with the stamping part of the...
