Seven major features of metal stamping die operation
(1) the product quality is stable and interchangeability is good. The metal stamping mould is adopted to form the product. There are few factors affecting the product quality change and the degree of harm is low. Some factors can be taken appropriate measures to correct, so that the product quality control in the ideal range of j product quality stability can effectively ensure its interchangeability. Good interchangeability is the basic guarantee of mass production. At the same time also conducive to product maintenance, replacement.
(2) the number of parts or technological content completed per unit time with high production efficiency is several times higher than the general processing method, even hundreds of times. And the metal stamping process can also be used on a set of mold, multi - part, multi - process content combination processing way to further improve production efficiency.
(3) high material utilization ratio through different layout methods, such as cross, oblique, multi-row, mixing, bushing, and even no waste layout, can effectively improve the material utilization rate and reduce the material cost of products.
(4) materials do not need heating. In general, materials do not need heating during stamping operations. This can not only save energy, reduce heating equipment and site occupancy, but also avoid the surface oxidation, burns and deformation of products caused by heating shape and size instability. It can also prevent the adverse effects of temperature rise on the mold.
(5) the mechanical properties of punching pieces are improved. Affected by the hardening phenomenon of metal stamping, the surface structure of punching pieces is compact, the hardness and abrasion resistance are increased, and the strength and rigidity of punching pieces are also improved.
(6) a wide range of products suitable for stamping forming. Can solve many general mechanical processing can not or difficult to complete the processing content, especially for some thin, soft, difficult, strange, micro parts, or non-metallic material parts processing, metal stamping forming is almost the only processing forming method.
(7) it is simple to operate, and the forming process and basic quality of products with low labor intensity are mostly guaranteed by molds and stamping equipment. The basic actions during operation are the same, and it is not affected by the complexity of products. Operators also do not have high technical requirements, after a short - term post training, can mount the post operation.
