The service life of precision drawing stamping parts should be paid attention to 'hardware'

The service life of precision drawing stampings should pay attention to the following points: 1. The precision drawing stampings should be strictly inspected before installation and use, and dirt should be removed. Carefully check whether the guide sleeves and molds of the precision drawing stampings are well lubricated. 2. Regularly check the turntable and mold mounting base of the punch press to ensure the coaxial accuracy of the upper and lower turntables. 3. Install the convex and concave molds on the turntable according to the installation procedure of the mold to ensure that the direction of the convex and concave drawing stampings is consistent, especially the precision drawing stampings with direction requirements (non-circular and square). Wrong, reversed. 4. When the punch and die cutting edges of precision drawing stamping parts are worn, they should be stopped in time and sharpened in time, otherwise it will rapidly expand the wear of the mold cutting edge, accelerate the wear of the mold, and reduce the quality and life of the die. 5. When installing the mold, the stamping personnel should use softer metals (such as copper, aluminum, etc.) to make operating tools to prevent damage to the precision drawing stampings during the installation process. 6. In order to ensure the service life of precision drawing stamping parts, the spring of the mold should be replaced regularly to prevent spring fatigue damage from affecting the use of precision drawing stamping parts. The service life of precision drawing stamping parts depends on factors such as reasonable mold structure, ultra-high manufacturing accuracy, good heat treatment effect, correct selection of punches, precision drawing stamping parts installation accuracy, etc., the correct use and maintenance of the mold And maintenance is also a link that cannot be ignored.
