Abstract：

It is a key step to form the car left/right corner reinforcing plate of which the side trimming-punching-separation die design based on the drawing die and side punching die. The side trimming-punching-separation die was designed according to the structure characteristics of the above workpiece. During the process of die design, the three key issues of die structure design were discussed and identified: (1) The position of the die was determined. The positioning device was designed alone because the processing location of the die was mainly in the lateral position. (2) The opening of the die was realized successfully. The lateral interference phenomenon was solved due to lateral punch in the die design. (3)The lateral punch position and stroke were controlled due to the design of stroke device. Production experiments show that the die design can guarantee product quality and reach the design goal.
