The role of metal stamping and drawing die

Date of release:2019-05-29 Author: Click:

Chengda Mould Factory takes you to know the function and some common knowledge of metal stamping and drawing die.

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

The metal stamping forming die is a kind of die which directly replicates 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 bulging die, necking die, expanding die, undulating forming die, flanging die, shaping die, etc.

Stamping materials are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plate, alloy steel plate, spring steel 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 does not generate chips and debris, consumes less material and does not need other heating equipment.

Hardware Stamping and Drawing Die-Jiaxing Chengda Die Co., Ltd.

Common sense: Hardware stamping and drawing die is a process that uses punch and die to deform or fracture iron, aluminium, copper and other sheets and other foreign materials, so as to achieve some shapes and sizes. Hardware stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet metal forming refers to the use of sheet metal, thin-walled tubes, thin profiles and other raw materials. The forming method of plastic processing is generally called sheet metal forming. At this time, the deformation in the direction of thick plate is generally not taken into account.

Hardware stamping and drawing die industry is a very wide range of industries, such as automobile industry, machinery industry, electronic device industry, etc. It goes deep into all aspects of manufacturing industry. In foreign countries, stamping is called sheet metal forming, which is also called in our country.

There are too many factors to be considered in the design of metal stamping drawing die, such as drawing coefficient, whether to reach the material limit, the determination of spring force, the direction of drawing, whether to stretch upward or downward, so that the ideal result can be achieved, even the possibility of die damage can sometimes be achieved. Therefore, it is very helpful for the design of drawing die to accumulate experience constantly in practice. .

These are the functions of some simple metal stamping and drawing dies and some common knowledge about them.
