How to solve the problem of material rebound in the processing of metal stamping parts in Wuzhong + 16 strict quality inspections

The stamping production staff responsible for the processing of metal stamping parts in Wuzhong said that there are some more complicated stamping parts, and the properties of the metal materials will be different depending on the material selected, so they will encounter the problem of material springback, so how To solve this problem? Let me understand with you the following: Analysis of the cause of springback: The positioner is worn out and deformed, and the strip is inaccurately positioned, and a new positioner must be replaced; In a non-guided bending die, the pressure is adjusted on the press Improper adjustment of the position of the bottom dead center of the machine slider 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, the pressing force must be re-adjusted or the pressure spring must be changed to make it work properly. In view of the poor springback of Wuzhong hardware stamping parts, Xiaoshuo suggests to deal with: Choose 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; materials must be carried out before bending Annealing, the cold work hardening material is softened in advance and then bent into shape. If the shape is deformed during the stamping process and it is difficult to remove; the slope 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; the contact area between the die and the workpiece should be increased, and the convex The contact area between the mold and the workpiece. Hardware, 15 years of focus on Wuzhong metal stamping parts processing, 20,000+ sets of mold customization processing and production experience, product accuracy can reach 0.01MM, daily production capacity of 3 million strokes and 16 quality inspections strictly for quality control. It can quickly solve your time-critical problems, solve your product accuracy problems, and solve your hardware stamping parts quality requirements. Choose, choose rest assured!
