A processing method for the front bushing of the swing arm of the automobile suspension

Abstract

The invention relates to the technical field of mechanical processing, in particular to a processing method for a front bushing of an automobile suspension swing arm. Under the positioning of the hole, the part to be removed on the side of the workpiece is cut off in batches and the waste is separated to process the upper ring and the lower ring; side forming, punching the workpiece into a preset shape to process two concave arms; Side shaping, trimming the two concave arms on the workpiece. According to the processing method of the front bushing of the swing arm of the automobile suspension, the positioning process hole is processed on the workpiece, and the processing mold and the positioning process hole cooperate with each other to trim the workpiece in batches, which can effectively reduce the edge trimming. The impact on the roundness of the workpiece, the waste material falls smoothly, the probability of processing mold stuck materials is greatly reduced, and the processing accuracy of the workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a front bush of an automobile suspension swing arm. Background technique [0002] The front bushing of the automobile suspension swing arm is a metal part, such as figure 1 As shown, it includes an upper ring 1, a lower ring 2 and two concave arms 3 for connecting the upper ring 1 and the lower ring 2, and the two concave arms 3 are arranged symmetrically. The front bushing of the swing arm of the automobile suspension is used to fix the internal rubber, connect the car body and the suspension, and play the role of connection and buffer. The front bushing of the car suspension swing arm is designed so that it can effectively reduce the vibration of the car while driving, improve the life of the rubber, and ensure the strength at the same time. [0003] In the prior art, the front bushing of the swing arm of the automobile suspension is most...

AI Technical Summary

Problems solved by technology

Since the product is a cylinder, the material utilization rate of the turning forming method is not enough, and the front bush of the automobile suspension swing arm needs to be stress-relieved after forming, and the processing cost is too high

Adopting the processing method of rolling and welding forming, the connection strength of the finished bushing of the front bushing of the automobile suspension arm is not enough, which reduces the quality of the product

The method of conventional sheet metal stamping processing cannot prevent the workpiece from rotating, the positioning is not stable enough, and the trimming accuracy of the workpiece cannot be guaranteed, so that the width of the two concave arms 3 is quite different, and the processing accuracy of the workpiece cannot be guaranteed; In this way, the radian of the edge trimming is large, the force on the workpiece is large, resulting in deformation of the workpiece, the roundness of the workpiece is low, and the powder is large, the waste material does not fall smoothly, and the processing mold is easy to jam the waste material and cause the processing mold to explode.
