ABSTRACT In this design according to the requirements of the topic, firstly, stamping parts are analyzed, the dimensional accuracy of the parts of the analysis that the general accuracy of the mould can meet the requirements of precision parts, from the shape, dimension and mass production situation, selection and processing scheme. Due to the importance of the mold industry, mold forming technology has been widely used in various industrial sectors, so that the mold industry output value has been greatly exceeded the machine tool industry output value. This fully explained in the process of national economy vigorous development, in the fierce competition for each industrial developed countries on the world market, more and more using mold for production, key technology and national economic development has become the mold industry obviously. Therefore, to make each department of national economic high speed development, accelerate the realization of the four modernizations of socialism, we must mold industrial make up as soon as possible, so that the mold production formed an independent industrial sector, so as to give full play to the key role of mold industry in the national economy. The design of bending plate stamping bracket parts of
