Cold heading die structure capable of adjusting direction of forming cavity

Abstract

A cold heading die structure capable of adjusting the direction of a forming cavity comprises an outer die shell and an inner die body, the inner die body is detachably arranged at the bottom of the outer die shell, the forming cavity is formed in the bottom face of the inner die body, an installation cavity is formed in the bottom of the outer die shell, the inner die body can be detachably connected into the installation cavity, threaded holes are distributed in the side wall, corresponding to the installation cavity, of the bottom of the outer die shell, corresponding adjusting screws are connected into the threaded holes in a threaded mode, the top ends of the adjusting screws stretch into the installation cavity and abut against the outer wall of the inner die body, and when the tail ends of the adjusting screws are screwed to change the length, stretching into the installation cavity, of the top ends of the corresponding adjusting screws, the position of the inner die body in the installation cavity is changed, so that the direction of the forming cavity is changed. The cold heading die structure capable of adjusting the direction of the forming cavity has the advantages that the requirement of form and location tolerance of a product is met by continuously and finely adjusting the length, extending into the installation cavity, of the adjusting screws in the debugging process, fine adjustment of the direction of the forming cavity is realized, and the cold heading die structure is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of mold making, in particular to a cold heading mold structure capable of adjusting the position of a forming cavity. Background technique [0002] For non-revolving cold heading parts, the original cold heading process has been unable to effectively solve the problem of shape and position tolerance of the product. In the existing cold heading forming process, the cold heading mold can only be rotated by the feeling of the cold heading master. After the cold heading mold is rotated, the clamping screw of the equipment is fixed to debug the product. The operation is random and cannot be realized only by manual feeling. Fine-tuning, it is difficult to debug the shape and position tolerance size that meets the product requirements, so the cold heading structure used in the existing process still needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present inventi...

[0002] For non-revolving cold heading parts, the original cold heading process has been unable to effectively solve the problem of shape and position tolerance of the product

In the existing cold heading forming process, the cold heading mold can only be rotated by the feeling of the cold heading master. After the cold heading mold is rotated, the clamping screw of the equipment is fixed to debug the product. The operation is random and cannot be realized only by manual feeling. Fine-tuning, it is difficult to debug the shape and position tolerance size that meets the product requirements, so the cold heading structure used in the existing process still needs to be improved
