Abstract：

According to the requirements of shape, size, material and production batch of inner support parts, the process analysis of inner support parts was carried out. Then, the traditional process scheme was improved, and the blanking process scheme with small scrap of eliminating clearances between workpieces was formulated to reduce the cost of stamping production. Due to the cancellation of clearancess between workpieces, the die work process was conducted smoothly by the working sequence of cutting, U-shaped bending, 45° bevel edge bending and forming, the production efficiency was improved, and the product quality was ensured. According to the blanking process scheme, for inner support parts, the progressive die with small scrap was designed, and the forming mandrel was wrapped by the forming materials. Furthermore, the materials after cutting was ensured to push each other and move, and the forming mandrel moved up and down to form the material. Finally, the characteristics and working principle of the die structure were analyzed, and the key structure and design points of the die were introduced.
