Introduction and function of metal stamping die

Metal stamping forming die is a die which directly copies the blank or semi-finished workpiece according to the shape of drawing and concave die, while the material itself only produces local plastic deformation. Such as expanding die, shrinkage die, expanding die, rolling forming die, flanging die, shaping die, etc.

Metal stamping drawing die is a die which makes blank of sheet metal into open hollow parts or makes hollow parts change shape and size further. Bending die causes the blank or other blank to bend along the straight line (bending curve), so as to obtain a certain angle and shape of the workpiece mold.

The materials for stamping parts processing are mainly hot rolled or cold rolled (mainly cold-rolled) sheet metal strip materials, such as carbon steel plate, alloy steel plate, spring plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc. Stamping is a kind of material saving and energy-saving processing method because it has no chip and scrap generation, less material consumption and no other heating equipment.
