Performance, precision stamping parts stamping stamping materials required:
1, stamping materials should be easy to get high quality and precision stamping parts with high precision, convenient production and processing.
2, stamping materials a limit pressing deformation limit degree and the total deformation degree should be large enough to improve production efficiency.
The loss of 3, stamping materials of precision stamping parts, precision stamping mould and wear low, and not prone to waste, so as to improve the yield.
Two, technical requirements of precision stamping stamping materials should meet the:
1, the thickness tolerance of stamping materials shall comply with the national standard: die gap different for different thickness of the material, if the thickness tolerance of the material is too large, not only directly affect the quality of stamping, may also lead to damage or die press.
2, the surface quality of stamping materials have higher surface cleaning materials: stamping formation, scale, rust, scratches, cracks, defects such as delamination. The surface state of good material, not easy to break in the process, is not easy to scratch mold, stamping the surface quality is good.
3, stamping materials should have good plasticity: stamping material should have high elongation and contraction rate, low yield and high squint of tensile strength, high plasticity, deformation degree, uniformity is conducive to the stability of stamping process and deformation, improve the dimensional accuracy of precision stamping forming a.
4, deal with mechanical stamping material bonding and continue processing (such as welding, polishing and other processes) have good adaptability and should not damage the mechanical equipment.
Precision stamping parts stamping materials, relationship with the performance and quality of stamping, stamping for material selection will need to comply with the relevant conditions above, to meet production requirements.
