First of all, conceptually, sheet metal processing refers to the processing of metal sheets, which is to use sheets to make common items in our daily life, such as chimneys, iron barrels, oil tanks, ventilation ducts, elbows, and rounded places. , funnel-shaped, etc., it is mainly made by cutting, bending, bending, bending, welding, riveting and other processes, and the stamping process relies on the power of conventional or special stamping equipment to make the sheet metal The production technology of product parts with certain shape, size and function that is directly subjected to deformation force and deformed in the mold. Sheet metal, mold and equipment are the three elements of stamping processing. From the above, it can be seen that stamping processing is only one of many processes in sheet metal processing, and the two are included and included.
Blocking is a stamping process that separates materials along the opening and outlines, and the separated materials become workpieces or process parts.

Flaring is a stamping process that expands the opening of a hollow or tubular part.

Punching is a stamping process that separates the waste material from the material or process parts along the closed outline, and obtains the required holes on the material or process parts.

Punching is a stamping process that separates the scrap from the material or process parts along the opening, and the opening forms a gap, the depth of which does not exceed the width.

Punching is a stamping process that separates waste materials or process parts along the opening surface. The opening surface is in the shape of a groove, and its depth exceeds its width.

Punching the center hole is a punching process in which a shallow concave center hole is formed on the surface of the process part, and the material on the reverse side has no corresponding protrusion.
