Precautions for drawing stamping parts
2. Regularly check the turntable and die mounting base of the punch press to ensure the coaxial accuracy of the upper and lower turntables.
3. Install the convex and concave die on the turntable according to the mold installation procedure to ensure that the direction of the convex and concave stretched stamping parts is consistent, especially the stretch stamping parts with direction requirements (non-circular and square) should be more careful to prevent wrong installation ,Anti-loaded.
Fourth, when the punch and die edges of the drawing stamping parts are worn, they should be stopped in time and sharpened in time, otherwise the wear degree of the die edges will be rapidly expanded, the die wear will be accelerated, and the quality of the stamping parts and the life of the die will be reduced.
5. Stamping personnel should use softer metals (such as copper, aluminum, etc.) to make operating tools when installing molds to prevent damage to stretched stampings during knocking and smashing during installation.
