ABSTRACT:Punching die has been widely used in industrial. more Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value. In this design, first we use the 3D sculpt function of UG to create 3D model of the part.During the procedure, the workpiece’s craftwork character is analyzed ,the workpiece’s 2-D drawing and 3-D mold are made, so that the workpiece can be better comprehended. Learn the structural craftwork character of the workpiece, so does the drawing and forming craftwork character. Make sure the workpiece’s craft project, compare them and make the final disicion. Calculate the size of the roughcast and select its shape. Calculate the times of the drawings , make sure the size of the semi-manufactured workpiece of every steps, and draw the working procedure’s sketch. Calculate the every working pressure, design and draw die’s sketch, select every appropriate parts. Comprehend every needed dies’ character and the issues that is needed to be payed more attention. On the base of the dies’ sketch ，the dies’structure is analyzed, and then go on designing their structures and selecting punch equipments.
