Jiangsu metal stamping parts, how to solve the rebound of stamping processing + 3 million punching next day production capacity

The technicians responsible for manufacturing the hardware of Jiangsu metal stamping parts said that stamping factories often produce various defects when producing stamping parts. The following Xiaoshuo analyzes the causes and provides preventive measures based on specific practices, and shares with you: Parts When bending, the size and shape are unqualified 1) Reasons: 　　 the rebound of the material causes the product to be unqualified; the positioner is worn out and deformed, and the strip positioning is inaccurate, and it must be replaced with a new positioner; , When adjusting on the press, improper adjustment of the bottom dead center position of the press slide will also cause the shape and size of the bent part to be unqualified; the pressing device of the mold fails or does not have a pressing effect at all, and the pressing force must be re-adjusted or Replace the pressure spring to make it work properly. 2) Measures to reduce springback: 　　 select stamping materials with large elastic modulus and small yield point and relatively stable mechanical properties; increase the correction process and use correction bending instead of free bending; the material should be annealed before bending to make the cold work hardened material soften in advance Then be bent into shape; if the shape is deformed during the stamping process and it is difficult to eliminate; the inclination of the punch and the die should be replaced or trimmed, and the gap between the punch and the die should be equal to the smaller material thickness; increase the gap between the die and the workpiece The contact area reduces the contact area between the punch and the workpiece; the 'overcorrection' method is adopted to reduce the impact of springback. Hardware, 15 years of focus on Jiangsu hardware 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 up to 0.01 mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
