Authors： MENG Yi-chang

Unit： Liuzhou Vocational and Technical Colleage

KeyWords： fender stamping process drawing die

ClassificationCode：TG316

year,vol(issue):pagenumber：2013,38(5):56-61

Abstract：

Based on the analysis of fender structures and process characteristics,and combined the simulation of Autoform software and design experience, the cause of cracking, the impact of line and rebound forming defects which appeared on fender molding process were analyzed. The ideas of increasing the punch fillet radiu, adding the process compensation height and adding the shaping process were put forward and the process program was simulated.The fender drawing die structure was designed and the main point of cover drawing die design and manufacture was also introduced.The practice shows that the cover drawing die has good process and reasonable structure which accords with production requirements.
