Chinese machine - feeder, precision stamping parts, stamping materials should have the conditions

I. The stamping properties of stamping materials for precision stamping parts
1, stamping materials should be easy to obtain high quality and high precision stamping parts, easy to production and processing.
2. The limit deformation degree and the total limit deformation degree of the stamping process of stamping material should be large enough to improve the production efficiency.
3, stamping materials for precision stamping parts, precision stamping die wear and loss is low, and not prone to waste, easy to increase production.
Two, precision stamping parts, stamping materials should meet the process requirements
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 material with good surface condition is not easy to break when it is processed, nor is it easy to abrade the mold, and the surface quality of the pressed parts 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, stamping materials should be mechanical bonding and continuous processing (such as welding, polishing and other processes) have good adaptability, should not damage the machinery and equipment.
The stamping material of precision stamping parts is closely related to the performance and quality of stamping parts, and the selection of stamping materials needs to meet the relevant requirements above, and meet the production requirements.
