Notes on the use of metal stamping parts

1、 Before the installation and use of stretching hardware stamping parts, it is necessary to strictly check and remove the dirt, and carefully check whether the guide sleeve and die of the stretching stamping parts are well lubricated.
2、 Regularly check the turntable of punch press and die mounting base to ensure the coaxial accuracy of upper and lower turntables.
3、 According to the installation procedure of the die, install the punch and die on the turntable to ensure the consistent direction of the convex and concave drawing stamping parts, especially for the drawing stamping parts with direction requirements (non-circular and square), pay more attention to prevent wrong installation and reverse installation.
4、 When the punch and die edge wear of drawing stamping parts, they should be stopped in time and sharpened in time, otherwise the wear degree of die edge will be rapidly expanded, the wear of die will be accelerated, and the quality and life of die will be reduced.
5、 The stamping personnel should use soft metal (such as copper, aluminum, etc.) to make operation tools when installing the mold, so as to prevent damage to the stretching stamping parts when knocking and smashing during the installation process.
6、 In order to ensure the service life of the drawing stamping parts, the spring of the die should be replaced regularly to prevent the spring fatigue damage from affecting the use of the drawing stamping parts.
In addition to the reasonable die structure, ultra-high manufacturing accuracy, good heat treatment effect, correct selection of punch and installation accuracy of stretch stamping parts, the service life of drawing stamping parts depends on the proper use, maintenance and maintenance of the die
