Analysis on the conditions that precision stamping parts should have for stamping materials_

Precision stamping parts are manufactured through a series of stamping processes such as stamping, extrusion, rolling, welding, and cutting. It is difficult to manufacture. In order to meet production requirements and achieve good product forming effects, for precision stamping parts The stamping materials have higher requirements. So what conditions should the precision stamping parts stamping materials have? The following author will analyze and answer for everyone. 1. The stamping performance of stamping materials for precision stamping parts: The stamping materials should be easy to obtain high-quality and high-precision precision stamping parts, which is convenient for production and processing. The limit deformation degree and the total limit deformation degree of the stamping material in one stamping process should be large enough to facilitate the improvement of production efficiency. Stamping materials have low loss and wear on precision stamping parts and precision stamping dies, and are not prone to waste products, which is convenient for increasing output. 2. Process requirements that should be met by stamping materials for precision stamping parts: The thickness tolerance of stamping materials should meet national standards: different die gaps are suitable for materials of different thicknesses. If the thickness tolerance of the material is too large, it will not only directly affect the quality of the stamping parts, but also It may also cause damage to the mold or press. Stamping materials have high surface quality: the surface of stamping materials is clean and smooth, free of oxide scale, cracks, rust spots, scratches, delamination and other defects. The material with good surface condition is not easy to break during processing, and it is not easy to scratch the mold, and the surface quality of the obtained stamping parts is also good. Stamping materials should have good plasticity: stamping materials should have higher elongation and section shrinkage, lower yield and higher tensile strength, higher plasticity and large deformation, which is beneficial to the stamping process The stability and uniformity of deformation have improved the dimensional accuracy of precision stamping parts. Stamping materials should have good adaptability for mechanical joining and further processing (such as welding, polishing, etc.), and should not damage mechanical equipment. The stamping materials of precision stamping parts are related to the performance and quality of stamping parts. The selection of stamping materials needs to meet the above relevant conditions and meet the production requirements.
