The use of metal stamping die is used when the stripper plate, or a fixed stripper, depending on the discharge capacity, the material thickness is the main consideration. With the increase of the elastic element elastic mould, pressing material unloading unloading plate greatly enhanced. According to the current situation, when the material thickness is less than 2mm by spring stripper, more than 2mm with fixed stripper is more close to the actual. The mould drawing material the material thickness of 1mm, so it can be used when the stripper. Metal stamping press and die by the sheet, strip, pipe and profile exerting force to produce plastic deformation or separation, thus obtaining the desired shape and size (Stamping) forming processing method. Stamping and forging are plastic processing, which is called forging. Stamping billets are mainly hot-rolled and cold-rolled steel plates and steel strips.
Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories. The separation process, also called blanking, aims to separate the metal stamping parts from the sheet metal along a certain contour line, while ensuring the quality requirements of the separation section. The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning and straightening are several main metal stamping processes. A large sheet metal stamping with surface and internal performance of stamping product quality requirements, stamping material accurate uniform thickness; smooth surface, no spots, no scar, no scratches, no surface crack; yield strength uniform, no obvious directivity; high uniform elongation; Qu Qiang ratio is low; low work hardening.
