As the present social progress and development, the original goods already can't satisfy people's demand for material, the manufacture of modities, however, must rely on the mold to production and , the development of the mould increasingly close relationship with people's use mould processing all kinds of artifacts, so that to satisfy people's 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 ponents 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 prehensive analysis of the parts, the I I design in the design of the mold is assembling a punching blanking die, p
