Automobile skylight reinforcing part cold stamping process

Abstract

The invention discloses an automobile skylight reinforcing part cold stamping process, and relates to the technical field of automobile part machining. The automobile skylight reinforcing part cold stamping process adopts the manner that forming is carried out, and then punching is performed for machining, the deviation condition of a hole is effectively prevented, and precision of a workpiece isensured. Side cutting and trimming are carried out after forming, the smoothness of the periphery of the workpiece can be ensured, a worker is prevented from being scratched in the subsequent machining process, the steps of workpiece discharging, workpiece forming machining, workpiece side trimming, workpiece hole machining and final shaping are adopted for machining, a product can be machined ata time, the yield is high, and the problems that due to a traditional machining process, cracking is prone to happening, a subsequently-assembled seal rubber sleeve fails, the safety property is affected, and the scrappage is high can be solved.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a cold stamping process of an auto sunroof reinforcement. Background technique [0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the entry of fresh air. At the same time, the car window can also broaden the field of view and meet the shooting needs of mobile photography. [0003] At present, traditional skylight reinforcements are blanked, drilled, turned, and trimmed, resulting in a low one-time pass rate of product processing, low production efficiency, and traditional processing techniques are prone to cracking, resulting in failure of subsequent assembly sealant sleeves and affecting safety. Performance, high scrap rate, high cost, and the situation that the workpiece is easy to scratch the operator during the processing, and when the traditional automotive sunroof reinforcement is processed, it is...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cold stamping process for automotive sunroof reinforcements, which solves the problem that traditional sunroof reinforcements use blanking, drilling, turning holes, and edge trimming, resulting in a low one-time qualified rate of product processing. Low production efficiency, the traditional processing technology is easy to crack, resulting in the failure of subsequent assembly sealing rubber sleeve, affecting safety performance, high scrap rate, high cost, and the situation that the workpiece is easy to scratch the operator during processing, and the traditional car sunroof When the reinforcement is processed, it is first punched and then formed. However, when punching, the punching cannot be accurately determined at the specified position, and the formed hole is prone to deviation.
