Method for machining forging die of radial forging machine through machining jig

Abstract

The invention provides a method for machining a forging die of a radial forging machine through a machining jig. The forging die comprises a mounting part and a forging part, and the machining jig comprises a shell, gaskets and a base. During clamping, the base is locked with the tail part of the mounting part of the forging die, and the shell and the gaskets are locked with the mounting part of the forging die. The machining jig can clamp a plurality of forging dies at the same time to conduct turning machining, the machining difficulty is lowered, the machining efficiency is improved, the dimensional uniformity of the multiple dies can be guaranteed, and the forging precision is guaranteed; the mounting groove position of the shell is matched with the taper of the forging die, so that the clamping operation is quick and convenient, and the machining difficulty is reduced; the gaskets have different thickness specifications, turning of arcs at different parts of the forging die is achieved by replacing the gaskets with different thicknesses, and operation is convenient; and the machining jig can be used for clamping forging dies of different models for turning machining, the structure is simple, space can be effectively saved, the manufacturing cost is reduced, and the universality is high.

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
