Mold processing refers to the processing of forming and blank making tools, including die-cutting molds and shearing molds. Usually, the mold consists of an upper mold and a lower mold, and the material is formed under the action of a press machine, with steel plates placed between the upper and lower molds. When the press is turned on, the workpiece determined by the shape of the mold will be obtained or the corresponding waste will be removed. From automotive dashboard components to electronic connectors, they can be molded using molds. Progressive mold refers to a set of molds that can automatically move processed workpieces from one workstation to another and obtain molded parts at the latter workstation. The mold processing technology includes four slide molds, extrusion molds, composite molds, punching molds, progressive molds, stamping molds, die-cutting molds, etc.

With the continuous deepening of social construction in our country, sheet metal parts have gradually been applied in people's lives. Normally, sheet metal processing is the process of cold working metal sheets to obtain sheet metal parts that meet application requirements.

Problem 1: The bent edge is not straight and the size is unstable reason: 1. The design process did not arrange for wire pressing or pre bending 2. Insufficient material pressing force 3. Uneven wear or uneven bending force on the rounded corners of convex and concave molds 4. The height dimension is too small

1. Cutting: There are various ways of cutting, usually using several combinations. a. Use a shearing machine to cut out the unfolded diagram, which includes the shape, length and width dimensions of the required sheet metal parts, combined with punching and die punching, corner cutting, etc;
