Precision hardware parts processing in the whole process, in addition to include: blanking, bending, deep drawing, forming, finishing and other processes, but also need to pay attention to is so to improve its quality, so that it can effectively extend its service life. Precision hardware parts processing materials used now hot rolled or cold rolled (mainly cold rolled) metal plate belt materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.. Such materials are used in the processing of precision hardware parts, which can effectively enhance their quality. When processing precision hardware parts, in order to better extend their service life in use, we need to pay attention to the following matters.

1. Strict inspection should be required before installation and use, and dirt should be removed. Carefully check whether the guide sleeve and die of metal stamping parts are well lubricated.

2. Check the rotary table of the punch press and the mounting base of the die regularly to ensure the coaxial accuracy of the upper and lower rotary tables.

3. According to the installation procedure of the mold, the convex and concave die is installed on the turntable to ensure that the direction of the convex and concave metal stamping parts is consistent, especially the metal stamping parts with direction requirements (non-circular and square) should be more careful to prevent the wrong installation and reverse installation.

4, metal stamping parts punch and concave die blade wear should be timely stop using, timely grinding, otherwise it will rapidly expand the wear degree of die blade, accelerate die wear, reduce punching quality and die life.

5, hardware processing personnel should use soft metal (such as copper, aluminum, etc.) to make operating tools in the installation process, to prevent the damage of metal stamping parts when knocking and smashing.

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