There are lots of knowledge of metal stamping processing. Now, KAIXIN sort out some common knowledge of them. There are the main measures to reduce the manufacturing cost, classification of stamping process, deformation in the stamping process.
Main measures to reduce manufacturing costs:
1. Improve the rationalization level of the process.
2, optimize mold design, reduce the process, improve the service life of the mold.
3. Improve the automation and speed of stamping process to reduce the cost.
4. Design molds for each workpiece to be processed at the same time.
5.Improve material utilization
According to the general deformation properties of materials, stamping processes are divided into two categories:
1. Separation process: under the action of external force, the stress of the deformation part exceeds the strength limit of the material and the plate is broken and separated.
2. Plastic deformation process: under the action of external force, the stress of the deformation part of the sheet exceeds the yield limit of the material, but when the strength limit is not reached, only the plastic deformation table is generated so that obtain a certain shape and size.
Five deformations in the stamping process
1. Stereo pressing: redistribute the volume and transfer the material to change the shape or height thickness of the blank.
2. Bending: bend the flat plate, make further changes to the shape. There are bends, warps, etc.
3. Calendering: pressing the flat blank into hollow parts of required shape, or further changing the size of hollow parts.
4. Molding: with various properties of local deformation to change the shape of parts or blank. The deformation including the revers, shrink, extrude, the volume circle, the shaping.
5. Cutting: This kind of way including blanking, punching, scraping edge, cutting off, sectioning etc.
Above are about the hardware stamping processing common knowledge.
