Abstract：

The characteristic of silent canopy structure design is to add the wavy rainwater drainage so as to decompose water rapidly, discharge water fast and send water in a lower noise. For the issues of wrinkle and crack in stamping the silent canopy, the optimization design of die structure was carried out. Various types of silent canopy stamping die were made of mosaic block 320, 400, 480 and 560 mm respectively. The blank of die was casted by lost foam, and nitrogen spring SNJ-500-32 was chosen as an elastic member of drawbead punch. The research results show that silent canopy parts producted by optimized die appear no wrinkling and cracking,which meets the design requirements. As a result, silent canopy were produced in batch production, which had produced sizable economic benefit.
