It is with low costs that there is the cold punchingly, product quality is steady, can process many kinds of performance , Part of the state. Its application and generallying receive the restriction in life-span of the mould and production safety,etc. at the same time . Author of this text proceed from rationality of the craft, analyse electrical machinery charcoal pastes up the structure of the shelf , Precision characteristic, and the control point in the course of processing, Consider and economize cost confirm electrical machinery charcoal brush blanking that shelf optimizes most process the process fully on the basis of satisfying the machining accuracy; And then pass the processing characteristic familiar with all kinds of moulds and inside structure, Finish the ensemble architecture analysis of the mould ; Author carry on blank size, arrange kind, process size, punching pressure, pressure in the center afterwards, mould work some size,etc. craft calculate, Strive to design the structure of every part of the mould and assembly relation with the best cost performance, Confirm the appearance of the mould on this basis, has finished the installation diag
