Forging process of automotive besides-star wheel

Abstract

The invention discloses a forging process of an automotive besides-star wheel, which comprises the steps of: sawing and blanking procedures, and a medium frequency induction heating procedure. The forging method is characterized in that the forging method further comprises the steps of: head and entrance upsetting procedure, combined extruding and pre-forging procedure, and combined extruding and finish-forging procedure after the medium frequency induction heating procedure. When the forging process is used to forge and stamp the automotive besides-star wheel, the procedures of the production process are reduced, raw material is saved, the material utilization ratio is improved, the production cost is reduced, the production efficiency is improved, the quality of the product is guaranteed and the purpose of stabilizing the production process is achieved. Meanwhile, the forging process has low requirement on sawing and blanking, and impact forces to a pre-forging die and a finish-forging die are small, thereby being good for prolonging the service life of the dies and for reducing the requirement on tonnage of the forging equipment.

Description

technical field [0001] The invention relates to the technical field of forging processing of automobile metal parts, in particular to a forging process of an automobile outer star wheel. Background technique [0002] At present, all kinds of automobile transmission systems use the outer star wheel as the key transmission part. To meet the technical requirements such as force and steering deviation when the wheel jumps, the working force situation is extremely complicated, and the state of the alien wheel in motion directly affects the safety, reliability and stability of the vehicle transmission. With the rapid development of the automobile industry, the market demand for various auto parts is expanding day by day. How to quickly and efficiently manufacture a large number of automobile outer planetary wheels is an industrial production problem that needs to be solved urgently. [0003] The outer star wheel product belongs to the cup and shaft parts, and its shape is relativ...

AI Technical Summary

Problems solved by technology

This processing method has the following problems and disadvantages: firstly, the material utilization rate is not high, generally around 80%, secondly, the service life of the forging die is not long and it is prone to die bursting, and thirdly, several forging equipment need to be invested to increase the number of operators , leading to higher production costs

This closed hot die forging process has huge capital investment in forging equipment, raw materials need to be weighed and unloaded, which reduces the utilization rate of raw materials and wastes production time
