Firstly, the processability of the product structure of the connection board and the specialty are analyzed, and the pressing process program of blanking-drawing-piercing in one forming process is formulated through analyzing different pressing process programs. And then the general design for the die is carried out, the assembly drawing of the die and the working process of the die are introduced. Then, we analysed operating and positioning method, material discharging and part discharging method, feeding mode, guiding mode, and so on. Next, the calculating and selecting for the pressing equipment is carried out, and the theoretical analysis and calculation and design for the main parts and the selection of the standard parts are carried out. The blanking-drawing-piercing compound die in one forming process is designed according to the above analyzing and calculating results. At last, the assembly and debug for this die are introduced. The pressing forming for the vehicle body mounting connection board can be realized quickly by this die, which not only ensures the machining quality, but improves the production efficiency. The designing method and process of this die provides referring values for other parts’ pressing dies.
