Design of progressive die for middle thick plate hinge support
Abstract：With the development of industry, the development of the mould industry more and more quickly. Through the analysis and comparison of forming three different stamping process in the process, the blanking and drawing process of the roof tiles. First, cutting, and then die drawing process. Mainly introduces the forming process of cold stamping parts quality, parts structure, and analysis of the use of mass production requirements of the roof tiles, based on the use of performance is not reduced, the basic premise, to determine the stamping parts, complete parts formed by stamping technology, including the overall design of stamping process analysis, process planning sure, the gap, the process parameters calculation and determine the pressure center, pressure equipment selection, mould parts design and die structure design etc.. The calculation of the workpiece mainly determine the size of parts. This paper also introduces the plate, punch, die, fixing plate, stripper plate and other parts of the design, the choice of the press and die choice.
