The basic characteristics of cold stamping die operation

The basic characteristics of cold stamping die operation

(1) High production efficiency. The number of parts or process content completed per unit time is several times higher than that of general processing methods, even hundreds to thousands of times. In addition, the cold stamping process can also use one mold with multiple parts and multiple process content combined processing methods on a set of molds to further improve production efficiency.

(2) The product quality is stable and the interchangeability is good. The cold stamping mold is used to form the product, and the factors that affect the product quality change are few and the degree of harm is low. Some factors can be corrected by taking appropriate measures to control the quality of the product within the ideal range. The stability of the product quality can effectively ensure its interchangeability. Good interchangeability is the basic guarantee for mass production of the assembly line. At the same time, it is also conducive to product maintenance and replacement.

(3) High material utilization rate. Through different layout methods, such as: cross, diagonal, multi-row, mixed, nested, and even no-waste layout methods, can effectively improve the utilization rate of materials and reduce products. The cost of materials.

(4) The material does not need to be heated. Under normal circumstances, the material does not need to be heated during the stamping operation. This not only saves energy, reduces heating equipment and site occupation, but also avoids shape and size instability caused by surface oxidation, burns, and deformation of products caused by heating. It can also prevent the adverse effects of temperature rise on the mold.

(5) The mechanical properties of punching parts are improved. Affected by the phenomenon of cold work hardening, the surface structure of the punching parts is tight, the hardness and wear resistance are increased, and the strength and rigidity of the punching parts are also improved.

(6) Wide application range There are many products suitable for stamping forming. It can solve many processing contents that are impossible or difficult to complete by general mechanical processing, especially for the processing and forming of some thin, soft, difficult, strange, micro parts, or non-metallic material parts. Cold stamping is almost the only processing method.

(7) Simple operation and low labor intensity. The forming process and basic quality of products are mostly guaranteed by molds and stamping equipment. The basic actions during operation are the same and are not affected by the complexity of the product. There are no high technical requirements for the operators, and they can start operation after short-term job training.
