Precautions for the use of metal stamping parts-stretch stamping parts

1. Stretch metal stamping parts should be strictly inspected before installation and use, and dirt should be removed. Carefully check whether the guide sleeves and molds of stretch stamping parts are well lubricated.

2. Regularly check the turntable of the punch press and the mold installation base to ensure the coaxial accuracy of the upper and lower turntables.

3. Install the convex and concave dies on the turntable according to the installation procedure of the mold to ensure that the direction of the convex and concave stretch stamping parts is consistent, especially for stretch stamping parts with direction requirements (non-circular and square) to prevent wrong installation. ,Anti-loaded.

4. When the punch and die edges of stretching 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 wear of the die will be accelerated, and the quality of the punching 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 the mold to prevent damage to the stretched stamping parts during knocking and smashing during the installation process.

6. In order to ensure the service life of the stretch stamping parts, the spring of the mold should be replaced regularly to prevent the fatigue damage of the spring from affecting the use of the stretch stamping parts.

The service life of stretch stamping parts depends on factors such as reasonable mold structure, ultra-high manufacturing precision, good heat treatment effect, correct selection of punching machines, installation accuracy of stretch stamping parts, etc., the correct use, maintenance and maintenance of the mold It is also a link that cannot be ignored.
