We often say that metal forming involves three concepts of forging, stamping and sheet metal making .
Forging: Under the action of heating equipment and molds, under the action of pressing equipment and tools, the blank or ingot is locally or completely plastically deformed to obtain the processing of forgings with certain geometrical dimensions, shapes and properties. The method is called forging.
Stamping: using the stamping equipment to provide power, using the mold to control the deformation of the stamping blank, so that the blank becomes the processing process of the product parts according to the expected requirements, including the separation process, ie cutting (cutting), punching (dropping), punching, repairing Edge, cutting, precision blanking, etc. and forming process; forming process, that is, bending (bending, bending, bending, bending, etc.), drawing, bulging, flanging, shrinking, crimping, Leveling, spinning, etc.
Sheet metal: use sheet metal equipment to provide external force, control the blank deformation or blank division by means of mold or laser, water, plasma, etc., so that the blank becomes the processing part of the part according to the expected requirements, including folding, bending, shearing, cutting, riveting and punching. Wait.
Stamping and sheet metal have overlapping processes. Sheet metal is the process of cutting and bending profiles and pipes by using equipment and molds to obtain parts of certain shapes.
