WANG Chong;JIN Long-jian;Guilin Electrical Equipment Scientific Research Institute Co.,Ltd.;Songbo Electric (Shanghai) Co.,Ltd.;
The stamping process of a hinge was analyzed, and the forming process including piercing, bending, rolling and cutting was put forward. The original layout with one part was changed to two parts, and the die structure was designed. Practice proved that the die structure was compact and the parts were qualified with good stability, which could provide reference for similar parts of progressive die.
