Cold Stamping Die

A cold stamping die is a type of die that applies a deformation force to the plate placed in it at room temperature. It is a special tool that is installed on a press and exerts a deformation force at room temperature to obtain product parts with a certain shape, size and performance. There are many forms of stamping dies, which can generally be classified according to the following main characteristics:

1. Classification according to the nature of the process

(1) Blanking die A die that separates materials along a closed or open outline. Such as blanking die, punching die, cutting die, slitting die, trimming die, cutting die, etc.

(2) Bending mold It is a mold for making the sheet blank or other blanks bend along a straight line (bending line) to obtain a certain angle and shape of the workpiece.

(3) The drawing die is a die for making the blank of the sheet into an open hollow part, or to further change the shape and size of the hollow part.

(4) Forming mold is a mold that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. Such as bulging molds, necking molds, flaring molds, undulating forming molds, flanging molds, shaping molds, etc.

Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger batches of parts, which is easy to realize mechanization and automation, and has high production efficiency. At the same time, stamping production can not only strive to achieve less waste and no waste production, but also has margins in some cases. The leftover material can also be fully utilized.
