Conditions for stamping materials of precision stamping parts
Precision stamping parts are manufactured by a series of stamping processing techniques, such as stamping, extrusion, rolling, welding and cutting, etc., which are quite difficult to manufacture. In order to meet the production requirements and achieve a good product forming effect, there are relatively high requirements for stamping materials of precision stamping parts.
What are the requirements for stamping materials of precision stamping parts?
Stamping performance of precision stamping parts
1. Stamping materials should be easy to get precise stamping parts of high quality and high precision, which is convenient for production and processing.
2. The limit deformation degree and the total limit deformation degree of the first stamping process of stamping materials shall be large enough to facilitate the improvement of production efficiency.
3. The loss and wear of stamping materials on precision stamping parts and precision stamping dies should be low, and waste is not easy to appear, so as to increase production.
2. The stamping material of precision stamping parts shall meet the technological requirements
1. The thickness tolerance of stamping materials shall conform to national standards: different die gaps shall be applicable to materials of different thickness. If the thickness tolerance of materials is too large, it will not only directly affect the quality of stamping parts, but also may cause damage to the die or press.
2. Stamping material has high surface quality: stamping material has clean and smooth surface without defects such as oxide skin, cracks, rust spots, scratches and delamination.The material with good surface condition is not likely to break or scratch the mold during processing, and the surface quality of the stamping parts obtained is good.
3. Stamping materials should have good plasticity: stamping materials should have high elongation and reduction of section, low yield narrowing and high tensile strength, high plasticity and large deformation degree, which is conducive to the stability of stamping process and the uniformity of deformation, and improves the precision of forming dimension of precision stamping parts.
4. Stamping materials shall have good adaptability to mechanical joint and continuous processing (such as welding and polishing) and shall not damage mechanical equipment.
The stamping material of precision stamping parts is related to the performance and quality of stamping parts. The selection of stamping materials should meet the above related conditions and meet the production requirements.
