Kunming metal stamping parts, how to solve the springback caused by bending of stamping parts + 15 years of experience manufacturer

The technicians of Kunming hardware stamping parts manufacturer said that stamping factories often produce various defects when they produce stamping parts. The following Xiaoshuo analyzes the causes and provides preventive measures based on specific practices, and shares with you: Part bending 1) Reasons: 　　 the rebound of the material causes the product to be unqualified; the positioner is worn and deformed, and the positioning of the strip is inaccurate, and a new positioner must be replaced; in the non-guided bending die, When the press is adjusted, the lower dead center position of the press slide is improperly adjusted, which 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 replaced. The spring makes 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 and formed; if the shape deformation occurs 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 contact between the die and the workpiece Area, reduce the contact area of u200bu200bthe punch and the workpiece; adopt the 'overcorrection' method to reduce the impact of springback. Hardware, 15 years of focus on Kunming 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 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 to rest assured!
