A processing system and processing method for a drag seat assembly

Abstract

The present invention proposes a processing system and processing method of the tray assembly. The processing system includes a stamping device for forming the tray body and a double-sided projection welding device for welding the tray body and the U-shaped bracket. The stamping device includes The edge trimming assembly station, wing edge forming station, side edge flanging station, wing edge punching station, wing edge bending station, arc body bending station, Shaping station and separation station, empty step stations are set between adjacent stations, trimming assembly station includes positioning punching-trimming station, side trimming station arranged in sequence along the conveying direction of the material belt station, the first wing edge trimming station and the second wing edge trimming station. The invention optimizes the design of the processing station, improves the dimensional stability of the main body of the drag seat, and eliminates the uneven distribution of relevant stress to the greatest extent; the redesigned mold structure adopts a block-type structure, which prolongs the life of the mold parts and shortens the maintenance time of the mold , to facilitate mold maintenance.

Description

technical field [0001] The invention relates to the field of processing a drag seat of a shock absorber, in particular to a processing system and a processing method for a drag seat assembly. Background technique [0002] The shock absorber is mainly to relieve the impact brought by the road surface, quickly absorb the shock generated by the bumps, and restore the vehicle to the normal driving state, which puts forward a series of high requirements for the shock absorber. The formation plays a key role in this process, directly affecting the strength, stability, lifespan, etc. of the shock absorber, and there are endless cases of abnormal noise, welding cracking, and fracture of the shock absorber on the market. The shock absorber bracket assembly includes the bracket body and the U-shaped bracket welded and fixed to the wing edge of the opening end of the bracket body. The bracket body is usually prepared by stamping a strip. The existing stamping process and devices have t...

AI Technical Summary

Problems solved by technology

The shock absorber bracket assembly includes the bracket body and the U-shaped bracket welded and fixed to the wing edge of the opening end of the bracket body. The bracket body is usually prepared by stamping a strip. The existing stamping process and devices have the following problems: process steps The design is unreasonable, resulting in low dimensional stability of the drag seat body, prone to defects such as excessive flanging stress and cracks in the flanging; uneven stress distribution, resulting in the occurrence of bursting and abnormal noise of the oil cylinder; the service life of stamping die parts is short , the maintenance cost is high, and it is not easy to replace or repair

[0003] In addition, CN208450815U discloses a double-sided welding device for the shock absorber bracket assembly, including a mandrel (or mandrel) for placing the bracket, but the mandrel is a cylindrical overall structure, and in the actual production process , there are the following disadvantages: 1. The mandrel is worn during the production process, which is prone to poor size and excessive pressing force; 2. When the stamping material leaves the factory, there is a certain tolerance in thickness and performance, so that the product will have a certain amount of pressure when the stamping die is produced. 3. In the production process, it is difficult to keep the mandrel and the side of the middle electrode parallel. If they are not parallel, it is easy to cause the size of the two ends of the product to be different.
