Function and common sense of metal stamping and drawing die for die manufacturers

Chengda mold manufacturer will take you to know the role of metal stamping and drawing dies and some common sense:

Function: Hardware stamping and drawing die is a die that can make blank into open hollow parts or further change the shape and size of hollow parts. Bending die is a die that makes blank or other blanks bend along a straight line (bending curve) to obtain workpieces with certain angles and shapes.

The metal stamping forming die is a die that directly copies the blank or semi-finished workpiece according to the drawing and the shape of the female die, while the material itself only produces local plastic deformation. Such as bulging die, necking die, flaring die, undulating forming die, flanging die, shaping die, etc.

The materials for stamping parts processing are mainly hot rolled or cold rolled (mainly cold rolled) metal sheet and strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinned plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc. Stamping is a material saving and energy saving processing method, because there is no chip material generated, the material consumption is less, and no other heating equipment is required.

General knowledge: metal stamping and drawing die is a process that uses a punch and die to deform or fracture iron, aluminum, copper and other plates and dissimilar materials to achieve some shapes and sizes. Metal stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet forming refers to the use of plates, thin-walled tubes, thin sections, etc. as raw materials. The forming method of plastic processing is generally called sheet forming. At this time, the deformation in the direction of thick plate is generally not considered.

The metal stamping and drawing die industry is an industry involving an extremely wide range of fields, such as automobile industry, machinery industry, electronic component industry, etc., which goes deep into all aspects of the manufacturing industry. Stamping is called sheet metal forming in foreign countries, as well as in China.

There are too many factors to consider in the design of the metal stamping drawing die, such as the drawing coefficient, whether it reaches the limit of the material, the determination of the spring force, the direction of stretching, whether it is stretching upward or downward. The ideal result can be achieved only after several trials, and sometimes the die may be damaged. Therefore, accumulating experience in practice is very helpful for the design of the drawing die.
