A method for machining a radial forging machine forging die by applying a machining jig

Abstract

The invention provides a method for processing a forging die of a radial forging machine using a processing jig. The forging die includes a mounting part and a forging part, and the processing jig includes a shell, a gasket and a base. When clamping, the base and the tail of the mounting part of the forging die are locked, and the shell, gasket and the mounting part of the forging die are locked. This processing fixture can simultaneously clamp multiple forging dies for turning processing, reduce processing difficulty, improve processing efficiency, and can ensure the dimensional consistency of multiple dies and ensure forging accuracy; the mounting slot of the shell is consistent with the taper of the forging die Matching, fast and convenient clamping operation, which reduces the difficulty of processing; gaskets have different thickness specifications, through the replacement of gaskets of different thicknesses, the turning of the arcs of different parts of the forging mold is realized, and the operation is convenient; this processing fixture can be used for clamping Different types of forging dies are turned, and the structure is simple, which can effectively save space, reduce manufacturing costs, and have high versatility.

Description

technical field [0001] The invention relates to the technical field of die processing for auto parts, in particular to a method for processing a forging die of a radial forging machine using a processing jig. Background technique [0002] With the requirements of energy saving and emission reduction in the automotive industry, it is bound to become a trend for hollow shafts to replace solid shafts. Radial forging is one of the common methods for processing tubular parts with internal shape. The processing of hollow shafts involves radial forging. The key to radial forging is the forging die. A forging die is a tool that can form a blank into a die forging. The forging die is used in the forging process. Under the action of external force, the raw material is plastically deformed in the forging die to obtain the required shape and size. [0003] Forging is generally formed by multi-step forming, and the structure is complex. Metal forging forming belongs to volume forming....

AI Technical Summary

Problems solved by technology

[0003] Forging is generally formed by multi-step forming, and the structure is complex. Metal forging forming belongs to volume forming. It is difficult to realize one-step forming and requires multiple deformations. Therefore, a set of forging dies often needs to be composed of more than one pair of dies, and a complete die is composed of four same mold composition

In addition, due to the high forging force of the radial forging machine, the damage to the forging die is large, and the life of the forging die is low. Moreover, due to the difference between different products, the corresponding forging dies are also different. When the shape of the product is complex, the number of corresponding forging dies , processing difficulty, and processing time will increase, and it will not keep up with the frequency of use of the mold, which will affect the output
