Abstract：

Based on the die design method of Deform-3D and UG/CAD, for the problems of high cost and low production efficiency in the single-process die production process of digital sectional switch shell, a design scheme of using multi-position progressive die instead of single-process die was proposed, and the stamping technological property of the digital sectional switch shell was analyzed. Then, the layout plan of product was designed, and the key parts were designed and calculated. Furthermore, a multi-position progressive die including punching, cutting, blanking and bending was designed, and the specific working process of die was explained. In addition, the elastic unloading device was used to discharge, and the production efficiency was improved. The numerical simulation analysis based on Deform-3D shows that the process plan, layout and die structure design of this die are reasonable. The experiment shows that the progressive die has a compact and reasonable structure, which is easy to manufacture and maintain, and it can meet the requirements of forming quality and production efficiency for part.
