Advantages of progressive die products for metal stamping manufacturers

1. 4 guide pin ball mold bases are mostly used, 4 small guide pins are used for the fixed plate of the punch, the discharge plate and the concave template, the upper and lower mold seats are S55C, and the upper template of the small and high-end mold is made of light weight and high hardness alloy. Aluminum, convex and concave mold materials are selected according to the material properties of the parts G5, G8 and SKD11, using a full-block combination structure, the processing accuracy is ±0.002mm, the cutting edge part Ra<0.1mm, after grinding, it is cryogenically treated ,HRC59-63. 2. The die block combination adopts a slot on the die base, the insert is fixed by screws, and the pull screw hole is set on it, which is easy to disassemble and replace. The two ends are compressed and positioned by the baffle, and the convex and concave die base is unloaded. All boards use SKD11

, dip hard HRC58-62.　　3. The blanking die is equipped with an elastic top core, and the elastic pressure is 20-30% of the punching force, and enters 60-80% of the thickness of the strip, which acts as an assembly line transfer belt.　　4. Compressed air shunt grooves are opened on the punch backing plate, leading to the φ0.7 small hole in the center of the punch to prevent chip jumping. .　　5. The punch adopts a floating fixed method, and the bilateral gap between the fixed plate and the fixed plate is about 0.015mm.　　6. u200bu200bOne mold for multiple purposes, slotting and inserting pins on the punch backing plate, pressing or loosening the punch. 7. A small air feeder with an accuracy of 0.02mm, up to 200 times/min, and a working pressure of 0.4MPa. It adopts a clamp-type structure and is equipped with a solenoid valve. The moment the guide nail is introduced into the strip, it acts as the solenoid valve. Next, the clamp is loosened to eliminate the accumulation of errors.　　 In general, the structure is compact and reasonable, with good rigidity, high precision, high degree of automation and production efficiency, reliable and safe operation, long life, suitable for mass production.
