【Abstract】 According to the structural characteristics and technical requirements of cold- forming profiles,the reasonable pressing technology scheme was worked out. The effect of different pressing technology on sheet- flow behavior was analyzed. The structure,work process and design of push and extrusion compound stamping die were introduced. Its compact structure,high efficiency and safe operation enable cold-forming profiles to locate accurately,form quickly and calibrate precisely.更多还原
