Manhole damper processing and separation process steps

Manhole damper sheet metal forming is also called stamping. This forming method is often performed at room temperature, hence the name cold stamping or sheet metal stamping. Based on its deformation characteristics, it can be divided into a separation process and a forming process. The separation process involves using a die to separate a workpiece of a specific shape and size under the external force of a press.

This includes processes such as blanking, punching, cutting, trimming, and slicing. The forming process involves using a die to plastically deform the sheet metal under the external force of a press to obtain the desired shape and size. This includes processes such as bending, drawing, flanging, bulging, expanding, shrinking, and spinning.

Manhole damper bulk forming: Secondary plastic processing involves using forging equipment, tooling, and dies to redistribute the volume of a metal blank (block) and plastically deform it to obtain a part with the desired shape, size, and performance. This primarily involves forging and extrusion. During the forming process, the shape of the deformation zone changes with the deformation of the former, which is a non-steady-state plastic deformation; the shape of the deformation zone of the latter does not change with the deformation in most deformation stages, which is a stable plastic deformation.
