原文：As the present social progress and development, the original goods already cant satisfy peoples demand for material, the manufacture of some commodities, however, must rely on the mold to production and processing.Therefore, the development of the mould increasingly close relationship with peoples life.We use mould processing all kinds of artifacts, so that to satisfy peoples needs, mould development brings us a new life, new era.This design is focus on the analysis of the blanking deformation process and the quality influence factors on the basis of blanking pieces, mainly introduces the technology of blanking pieces cutting process is analyzed and determined, and the choice of mould structure, make the necessary process calculation, the selection and determination of main components of the mold structure and size of the related parameters, height and press dies and drawing die assembly drawing and part drawing are the main content of this design.According to the requirement of the given topic in the design, I firstly analyses the stamping parts, analysis the size precision of the parts with general precision mould can meet the requirements of precision parts, from the shape of the parts, dimensioning and production batch, chose the punching blanking.According to comprehensive analysis of the parts, the I I design in the design of the mold is assembling a punching blanking die, punch blanking mould are mainly introduced, one of the most widely used process in stamping production.Due to the material and thickness, I use the processing method is: the composite process punching blanking die for processing.Key words: punching, blanking, edgeMould is the most basic part of the production of industrial unit, she is the national basic equipment, the production progress, it represents the production of industrial level measure of countries and regions.In die mould manufacturing, automobile, machinery, electrical appliances, all kinds of electrical machine has a pivotal
