The processing and separation process steps of manhole damper

Author:JingJiang Woken Mechanical Co., Ltd Time:2023-06-19

Manhole damper sheet forming is also called stamping. This forming method is mostly carried out at room temperature, so it is also called cold stamping or sheet metal stamping. According to its deformation characteristics, it can be divided into separation process and forming process. The separation process is a stamping process in which the workpiece with a certain shape and size is separated by the mold under the action of the external force of the press.

Including blanking, punching, cutting, trimming, slicing and other processes; The forming process is a stamping process that uses the die to produce plastic deformation of the sheet material under the external force of the press to obtain the required shape and size of the workpiece. Including bending, drawing, flanging, expansion, flaring, shrinkage, spinning and other processes.

The volume forming of secondary plastic processing is the use of forging equipment, tooling and molds to redistribute the volume of metal blanks (blocks) for plastic deformation to obtain the required shape, size and performance of the parts. Mainly includes forging and extrusion. In the forming process, the shape of the deformation zone changes with the deformation of the former, which belongs to the unsteady plastic deformation. The shape of the latter deformation zone does not change with deformation in most deformation stages, which belongs to stable plastic deformation.
