Discharge form of precision metal stamping parts

Metal stamping parts and castings, forgings, compared with a thin, uniform, the characteristics of light and strong. Stamping parts processing can make other method is difficult to manufacture with reinforcing rib, rib flanging, ups and downs, or artifacts, in order to improve its stiffness. Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc. Metal stamping parts used in the mould is to use pressure stripper plate, or with fixed stripper plate, depends on the size of the discharge power, the material thickness is a major factor. Due to the pressure discharge die mold operation than fixed unloading is convenient, the operator can see the material into action in the mould, and keeping the stripper plate discharging toward a strip material is flexible force, will not damage the surface, so as far as possible in the design of the actual mining pressure stripper plate, and only in the stripper plate discharging pressure force is insufficient, to switch to fixed stripper plate. With the augmentation of the mold with elastic element ( If use rectangular spring) , keeping the stripper plate unloading force greatly enhanced. According to current situation, when the material thickness is about 2 mm below the stripper plate, pressure is greater than 2 mm when using fixed stripper plate is more close to actual. This mold material thickness is 1 mm, so can use snap stripper plate. A: inhibition of metal stamping parts distortion method
