Metal stamping parts process first, drawing: the straight pieces of wool or step into the hollow member, or further change the shape of the hollow piece suits and size of a stamping process. Drawing temporal core member mainly rely on material located outside the punch die to form the bottom of the inflow. Second, trimming: the use of metal stamping dies trim the edges forming process, so that it has a certain diameter and a certain height or a certain shape of a stamping process. Third, punching: the waste along the closed contour separated from the material or process parts of a stamping process to obtain the required holes in the material or workpiece. Fourth, flanging: along its side around the shape of the curve will be translated into the short side of a stamping process. Fifth, turn the hole: the material around the perimeter of the hole translated into its side flange of a stamping process. Sixth, blanking: material separation along the closed contour of a stamping process, the separated material into the workpiece or process parts, metal stamping what is, most of planarity. Seventh, plastic: relying on material flow, metal stampings, a small amount of change in step shape and size, where expensive metal stamping, hardness testing to ensure the accuracy of a piece of metal stamping parts stamping process very broad range of applications and processing metal stamping parts Rockwell hardness. Small, stampings, metal stamping having a complicated shape can be used to test the plane is very small, can not be detected on a normal desktop Rockwell hardness. Stamping parts processing including punching, bending, drawing, forming, finishing and other processes. Materials stamping parts mainly hot-rolled or cold-rolled (cold-rolled-based) metal strip material, such as carbon steel, alloy steel plate, spring steel, galvanized sheet, tin plate, stainless steel, copper and copper alloy panels, aluminum and aluminum alloy plates.
