Flat washer manufacturer, improved efficiency and quality +15 years of focus on the production plant

Manufacturers of flat washers often encounter a variety of poor quality in the production of flat washers, which increases defective products and reduces production efficiency. Xiaoshuo sorted out several common phenomena and worked with you to understand: 1． Burr occurs. (1) Reasons: A. The knife edge is worn; B. The effect is not obvious after the clearance is too large; C. The knife edge is chipped; D. The clearance is unreasonable up and down or loose; E. Up and down misalignment. (2) Countermeasures: A. Research the knife edge; B. Control the processing accuracy of the convex and concave die or modify the design gap; C. Research the knife edge; D. Adjust the blanking gap to confirm the wear of the template hole or the processing accuracy of the molded part; E. Replace the guide Pieces or re-molding. 2. Jumping chip crush (1) Reasons: A. The gap is too large; B. Improper feeding; C. The punching oil drops too fast and the oil is sticky; D. The mold is not demagnetized; E. The punch is worn and the crumb is pressed against the punch. Top; F. The punch is too short, and the length of the insert is insufficient; G. The material is hard, and the punching shape is simple; H. Emergency measures. (2) Countermeasures: A. Control the processing accuracy of the convex and concave molds or modify the design gap; B. Trim the material belt when it is sent to the appropriate location and clean the mold in time; C. Control the amount of stamping oil drips, or change the oil type to reduce the viscosity; D Mold , Demagnetization after training (more attention should be paid to the punching material); E. Research the punch edge; F. Adjust the length of the punch blade into the die; G. Change the material and modify the design. The punch is inserted into the end face to push out or trim a bevel or arc (pay attention to the direction). Reduce the bonding area between the end face of the punch edge and the chip; H. Reduce the sharpness of the die edge, reduce the amount of training on the die edge, and increase the surface roughness (coating) of the straight edge of the die. Use a vacuum cleaner to suck up the waste. Reduce the impulse speed, slow down the jumping chip. 3. Chips blockage (1) Reasons: A. The leakage hole is too small; B. The leakage hole is too large, and the chip rolls; C. The knife edge is worn and the burrs are large; D. The punching oil drops too fast and the oil is sticky; E. The surface of the straight edge of the die is rough, and the powder sintering adheres to the edge; F. The material is soft; G. Emergency measures. (2) Countermeasures: A, modify the leakage hole; B, modify the leakage hole; C, trim the knife edge; D, control the amount of dripping oil, change the oil type; E, surface treatment, polishing, pay attention to reducing the surface roughness during processing ; Change the material, F, modify the blanking gap; G, trim the slope or arc on the end face of the punch blade (pay attention to the direction), use a vacuum cleaner, and add air to the blanking hole of the backing plate. Hardware, 15 years of focus on flat washer manufacturers, 5,000 square meters production workshop, hundreds of precision processing production equipment, 20,000+ sets of flat washer mold customized production experience, more than 20 Ru0026D and design engineers, flat washer stamping accuracy can reach 0.01mm, flat The precision of the washer can reach 0.01mm, and the 16 quality inspections strictly control the quality from the raw materials layer by layer. Can quickly solve the problem of time, accuracy and quality for you!
