1. The static punching process of the valve plate eliminates honeycomb defects in the cutting section, improves the quality of the tongue spring punching section with narrow gaps, and enhances its ability to resist impact stress and alternating stress;
2. The modular quick change structure with a 0.1mm blade thickness for convex and concave mold cores improves the efficiency and compatibility of concave and convex mold cores, ensuring that the punching force is more concentrated on the mold core, while reducing mold manufacturing costs and punching power consumption;
3. High speed, effective narrow clearance, and high consistency valve plate tongue spring edge chamfering technology. Explored the combination of ideal cross-section R angle polishing parameters to improve the valve plate's resistance to high frequency impact and alternating stress fatigue strength;
4. Based on image recognition and digital inspection technology for valve surface quality, the rapid removal of defective products with surface appearance defects has been achieved, greatly improving production efficiency and intelligent quality control level.
