Metal stamping parts are formed by stamping process of metal stamping process and die, stamping equipment and stamping materials. The advantages of metal stamping processing are high productivity, low mold cost, no need for sheet metal cutting, and 30% savings for progressive die. The cost, but its application is limited by the depth of the stretch, the orientation and the surface hardening of the strip material of the transport, and is mainly used for simple parts with a shallow depth of stretch.
Mold is the main process equipment of metal stamping processing. The surface quality, dimensional tolerance, productivity and economic benefit of stamping parts have a great relationship with the mold structure and its rational design. According to the combination of metal stamping process, there is a simple mode of single process. Multi-process continuous and composite molds.
When formulating the stamping process of the workpiece, the dispersion and concentration of the processing procedure is a relatively complicated problem. It depends on the batch size, structural shape, quality requirements, process characteristics, etc., and should be taken as much as possible for automotive stamping parts that are usually mass-produced. The process-focused solution uses a composite or progressive die for stamping, which increases productivity and enables safe production.
