| Abstract: | A new processing method for piercing on rectangular tube was put forward after an analysis on conventional process for close placing rack. Various processing plans were discussed and a piercing mode with male die but no female die was adopted. The structure of the die and key points in design were introduced. The shape of the male die cutting edge was determined by experiment. The products punched had minimal burr and smooth section. |
