Metal stamping is the use of punch and die stainless steel, iron, aluminum, copper and other plates and heterosexual materials to make its deformation or fracture, to have a certain shape and size of a process. Metal stamping parts processing generally uses stamping die production. This way is suitable for small batches of products or limited production of new products. This method can make products in a timely manner without molds or with simple molds.
There ARE MANY PROCESSES INVOLVED IN STAMPING, EACH OF WHICH MAY BE PROCESSED IN MANY DIFFERENT ways. Today the Metal Stamping Manufacturers is going to introduce the different processes involved in deformation.
In metallic materials, the forces acting between the atoms are strong enough to resist the action of gravity, so that in the absence of other external forces, the metal object will retain its shape and size. During metal stamping, the external force acts on the blank through the die, which causes the internal stress and plastic deformation. The action mode and size of a certain force correspond to a certain deformation, and the deformation is different with different forces. The stamping forming processing method and other processing methods, are based on their own performance as the processing basis, the implementation of the material stamping forming processing must have a good stamping forming performance. Metal stamping parts processing deformation processing in the following ways to achieve the desired effect.
1, cutting, blanking: not closed or not closed so that part of the material and another part of the separation. These kinds of ways are blanking, punching, cutting, cutting, cutting, incision and so on.
2, bending: the flat sheet material into bending parts, so that the shape of bending parts for further change. There are bends, curls and twists.
3. Calendering: the flat blank is stamped into the hollow parts of the desired shape, or the size of the hollow parts is further changed.
4, forming: with a variety of local deformation flat properties to change the shape of the workpiece or blank. Belongs to the deformation of the rolling molding, flanging, shrinkable neck, convex belly, roll round, plastic.
5. Stereoscopic pressing: the volume is redistributed and the material is transferred to change the shape or height of the blank. In order to improve productivity in the process of stamping parts, several basic deformation processes can be merged to form a new process, known as the composite process.
