The thickness tolerance of stamping materials should conform to national standards

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 are the conditions for precision stamping parts stamping materials? The following is an analysis and answer for everyone. 1. The stamping performance of stamping materials for precision stamping parts: 1. Stamping materials should be easy to obtain high-quality and high-precision precision stamping parts, which is convenient for production and processing. 2. The limit deformation degree and the total limit deformation degree of one stamping process of stamping materials should be large enough to facilitate the improvement of production efficiency. 3. The loss and wear of stamping materials to precision stamping parts and precision stamping dies should be low, and waste products are not easy to appear, which is convenient for increasing output. Second, the process requirements that the stamping materials of precision stamping parts should meet: 1. The thickness tolerance of the stamping material should meet the 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. Quality may also cause damage to the mold or press. 2. The stamping material has high surface quality: the surface of the stamping material 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. 3. The stamping material should have good plasticity: the stamping material should have higher elongation and section shrinkage, lower yield and higher tensile strength, higher plasticity, and a large degree of deformation, which is conducive to The stability of the stamping process and the uniformity of deformation have improved the forming dimensional accuracy of precision stamping parts. 4. 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.
