Abstract

The invention discloses a hub bearing flange plate multi-station precision forming technology and an implement device thereof. A blank is sequentially subjected to independent technologies including cutting blanking, upsetting, rod part forward extrusion, combined extrusion, forming and punching through a multi-station forming mold, and the optimizing forming of hub bearing flange plates is realized. According to the hub bearing flange plate multi-station precision forming technology and the implement device thereof, the blank plastic forming process is subjected to optimizing material allotment through the multi-station forming, and on the basis, upper mold and lower mold guide structural design, closed type forming technology design and a design technology combining nitrogen spring pressing with ejection are added, and the problems of low precision and many waste materials in the forming process are solved.

Description

technical field

[0001] The invention relates to a technology in the field of metal hot forming, in particular to a multi-station precision forming process of a hub bearing flange forging and a device for realizing it. Background technique

[0002] The key parts of the hub bearing are important components in the chassis of the car, and the flange of the hub bearing belongs to the more important category of the key parts of the hub bearing. The traditional hub bearing flange production uses a single-station open hot die forging process. The process of directly forming raw materials has obvious disadvantages, such as: more waste, poor product flow, and low product precision. Therefore, how to optimize the forming process and mold design is an urgent problem to be solved.

[0003] At present, for the wheel bearing flange forming process and mold design, the open multi-station (multiple equipment connection) hot die forging process is used. This process improves the product flow...
