and a 53° diagonal layout scheme was selected, which included six punching stations, one bending station,one empty station and one cutting station. Furthermore, based on the layout, a die was designed, namely, the bending part was bent upward to reduce the height of floating; the bending punch was installed on the discharge plate, and floating nails were designed to ensure the stability of bending; the small punches were designed with protective sleeves to enhance the punch strength; a quick-change design was adopted for the easy-to-wear punch,and an insert design was used for the dies which was casy to processing and replace; the rolling guide posts and guide bushes were used for the precise alignment of die clearances to ensure smooth operation; the floating guide pins, small guide posts and guide bushes, and positive guide pins were used in combination for accuracy of feeding and forming, and limit blocks were designed to protect the die. The result of test shows that after trial production, the die structure design is reasonable, and the size and precision of parts meet the requirements.
