Compared with the castings, forgings, pressing with a thin, uniform, the characteristics of light and strong.
Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness.
Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc.
Stamping machines, cold stamping parts generally no longer by machining, or only need a small amount of machining.
Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity.
Stamping is to rely on press and die for sheet, strip, pipe and profiles, such as external force, make its produce plastic deformation or separation, thus to obtain the required shape and size of the workpiece,
The forming method.
Stamping and forging belong to plastic processing (
Or pressure processing)
, called the forging press.
Stamping of billet is mainly hot rolling and cold rolling steel plate and steel belt.
