Zunhua metal stamping parts, what are the common problems of stamping processing + 16 strict quality inspections

The hardware technicians of the manufacturer responsible for metal stamping parts in Zunhua said that common problems in metal stamping processing include: deformation and burrs of precision stamping parts; cracks, warpage, surface scratches, angular deformations, etc. of bent parts; deep-drawn parts Flange wrinkles, deep-drawn wall wrinkles, deep-drawn wall damage, tearing, etc.; flanging cracks, uneven bulging, etc.　　 The solution to common problems: mold design should have reasonable convex and concave mold clearance value, fillet radius and processing accuracy. When designing a bending die, effective measures should be taken to reduce the springback, and the amount of springback should be subtracted from the mold; reasonable rounded corners should be designed to prevent bending cracks. When drawing, use a blank holder to prevent wrinkles, and the pressure should be moderate; use proper lubrication to reduce the drawing resistance to prevent the mold from sticking or make the workpiece pull through; use the special punching oil that meets the process requirements. Hardware, 15 years of focus on Zunhua metal stamping parts, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy 0.01mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled.
