With todays technology development, industrial production has been growing mold caused by the use of attention. Stamping die can greatly improve labor productivity, reduce the burden of workers, technological progress has an important significance and economic value. This paper describes the development of stamping die, stamping die design shows the importance and significance of this design. By access to information, to process analysis of the parts to complete the process of determining program. And then proceed to the tensile force, the calculation of blanking and tensile strength, punching part of the design and calculation of the work; the main components of the design and selection of standard parts. Calculated through the above-mentioned compound die to complete the forming and drawing. Finally, the convexity module designed for CNC machining simulation. The dies here discussed can be easily made, conveniently used, and safely operated. And it could be used as the reference in the large scale production of similar workpieces. Keywords: Compound
