Characteristics of sheet metal stamping process


Sheet metal stamping is a processing method that uses a die to separate or deform the sheet metal. Because in most cases the sheet metal does not need to be heated, it is also called cold stamping, also referred to as cold stamping or stamping.

Commonly used plates are mild steel, stainless steel, aluminum, copper and permalloy, etc., which have high plasticity and low deformation resistance, and are suitable for cold stamping.

Sheet metal stamping is easy to realize mechanization and automation, and the production efficiency is high; The size of the stamping parts is accurate and the interchangeability is good; The surface is smooth and clean, no machining is required; It is widely used in manufacturing industries such as automobiles, electrical appliances, instrumentation and aviation.


Process characteristics:

Stamping is the use of high-speed punches and dies to apply pressure to the material, so that it can produce a specific size of product according to a certain shape, and the product does not need additional processing after production. This production method is mainly used for metal coil forming processing. Stamping and forming under the conditions of large-scale production, although the high-speed punch and die have large capital investment and high production requirements, but compared with traditional methods (such as forging, casting, welding, mechanical cutting, etc.), its advantages are more obvious:

    1) After using high-speed punching press, the production efficiency is high, the production of parts is high-precision, and the quality is stable.

    2) The stamping parts of the high-speed punch press generally do not need to be machined, and the products are directly used for assembling products after surface treatment. Forming in one step, reducing the number of other processes.

    3) The material utilization rate is high, and the products with high strength, good stiffness and light weight can be obtained under the condition of saving raw material consumption.

    4) The progressive die stamping process can produce complex parts that are difficult to achieve by other processing methods.
