It is been productivity high that stamping has , product size precision stabilize and operate simple , finished cost low , overall material utilization factor high, easy realization a series of advantages such as mechanization and automation, suit plenty of productions especially. This text talks about our country pressing molding tool manufacturing technical present condition and the development trends currently. This article is mainly according to the requirements of the parts production technology, design the corresponding mold. Because board material, equipment and mould are the 3 necessary factors that form stamping processing , 3 this essential factors is stamping the hardware condition of place necessity, know again surpass Men for them in coordinate anicly, include carrying out reasonable technology design and calculation so as effective anization manages. Which content includes mainly :The priciple analysis of Drawing ,the technical analysis for Drawing ,design and calculate for the die structure. There have fully utilized CAD in the design [CAD/CAM]:Have drawn all part pictures and installation diagrams with Auto CAD 2021. In entire design course , the design of minute element processing technology and mould is same and important, at the same time, mould is to serve actual production place , so, the mould structure that devised will be not only feasible , reaches expected purpose and to let worker operating and simple, convenience is as far as possible few additionally to spend money, economy. In the interest of reducing cost,Most materials of mould accessory are choicing the usual material .This mould is easy to can used on the usual punch,and adapt to generalize in producing.
