Maintenance and maintenance methods of metal stamping dies [hardware]

Maintenance and maintenance methods of hardware precision stamping dies: 1. Before use, check whether the status of the metal stamping die is intact and whether the stamping materials used meet the requirements of the process drawings to prevent damage to the mold due to raw materials that do not meet the requirements, and the production of metal stamping parts cannot be completed. 2. The punch is prone to breaking, bending and gnawing during the use of the mold, and the punch sleeve is generally gnawed. Damaged punches and sleeves are generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the installation part, the length dimension, etc. 3. Check the looseness of each set of molds, check the screws and fastening parts, and check whether the fastening parts are loose or damaged. Find the parts of the same specification for replacement. 4. Springs and other elastic parts are most easily damaged during use, and they usually appear to be broken and deformed, which requires careful inspection. Replace damaged and failed springs and other elastic parts (pay attention to the specifications and models of the springs) 5. The metal stamping die must be sharpened after long-term use. After grinding, the cutting edge must be demagnetized and cannot be magnetized, otherwise it is easy to occur Blocking material. 6. After the hardware precision stamping die is used, the surface needs to be cleaned to remove oil dirt, dust and other sundries, so as to achieve a clean appearance, no rust, and no grease. For the maintenance and maintenance of metal stamping dies, operators need to pay attention to the daily work, do a good job of detail, and make every maintenance work in place to avoid failures, so as to extend its service life.
