ABSTRACT

This graduation design is focused on the blanking, basic process and the calculation of the mold and the design, the graduation design on the basis of the basic theory of stamping, elaborate on the design of the blanking die and bending die principle, method of application, are particularly hedge cutting, the design and calculation of all kinds of technology and die. Examples in this paper, the mold structure is simple and practical, convenient and reliable use, first of all, according to a development size work-piece figure is in according to the size to calculate the pressure center of the parts, material utilization, painting row kind diagram. According to the requirements of the parts geometric shape and size analysis, adopting compound stamping die, so that to improve the production efficiency, mold design and manufacturing is relative to the simple. When all the parameters are calculated, the mould assembly scheme, the design of main parts and assembly technology requirements are analyzed.
Key words: blanking; Stamping; design
