Auto metal stamping parts manufacturers, how to solve the springback caused by the bending of stamping parts + 15 years of experience manufacturers
Technicians from manufacturers of automotive metal stamping parts said that stamping factories often produce various defects when producing stamping parts. The following Xiaoshuo analyzes the causes based on specific practices and provides preventive measures to share with you: When parts are bent , Size and shape are unqualified 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 a non-guided bending die, under pressure When adjusting on the machine, 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 die pressing device fails or does not have a pressing effect at all, the pressing force must be re-adjusted or the pressure spring must be replaced 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 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 automotive hardware stamping parts manufacturers, 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. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose to rest assured!
