Combined die for forging gear shaft through moulding bed and forging technology

Abstract

The invention provides a combined mold for forging a gear shaft with a tire mold and a forging process, which belong to the field of forging. The combined mold includes: a lower mold body and an upper mold body; the lower mold body includes a shaft cavity of the lower mold body and a lower mold Body tooth cavity, the upper mold body includes a tooth cavity; the lower mold body is provided with a shaft cavity, and the shaft cavity is used to shape the shaft of the gear shaft. The tooth cavity of the mold body is used to form the lower half of the tooth portion of the gear shaft, and the tooth cavity of the upper mold body is used for the upper half of the tooth portion of the gear shaft; the upper mold body is arranged on the lower The upper part of the phantom. The invention provides a combined mold for forging a gear shaft with a tire mold, which can effectively reduce the machining allowance and save material consumption and machining time. The present invention also provides a forging process for forging a gear shaft with tire molds, which adopts the above-mentioned combination die for forging, improves forging precision, saves material consumption, and reduces production costs.

Description

technical field [0001] The invention relates to the field of forging, in particular to a combined mold for forging a gear shaft with tire molds and a forging process. Background technique [0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. The gear shaft is generally in the shape of a metal round rod, and each section can have different diameters, and the gear shaft is generally composed of a gear shaft rod portion and a gear shaft tooth portion. [0003] The existing gear shaft roll forging process is mainly a simple free forging production process, the blanking weight of raw materials is relatively heavy, the unilateral margin after forging is large, the subsequent processing cycle is relatively large, and the forging flow line is destroyed. It has disadvantages: large machining workload and low material utilization rate. When processing the size of each part of the part, a larg...

AI Technical Summary

Problems solved by technology

It has disadvantages: large machining workload and low material utilization rate

When processing the dimensions of each part of the part, a large amount of metal materials are cut off, resulting in serious material waste

The size of forgings changes frequently, which is not conducive to production management

Using free forging, the size of various types of drum body forgings depends on the size of their respective parts. Due to the similar shape and size, it is easy to confuse each other during the process movement and make mistakes.
