1. Inspection and maintenance of board cleaning equipment: Before production, it is necessary to check and maintain the metal stamping machine at the same time to make the custom cleaning of hardware machining more effective. Pay attention to the quality of roller and clean oil.

2. Appropriate manual speed: Material testing the parts produced before production. Reasonably set the speed and unloading angle of the robot to make it do not contact the manufactured parts and lower molds, thereby avoiding semi -automatic stretch production. When the stretch of the stretch is in the lower mold position, the operator is fast, and the burrs will fall on the punch, causing the metal indentation to uneven.

3. Check and correct the cutting method: Observe before pressing to avoid uneven iron powder. The iron powder generated during the cutting process will also cause uneven metal stamping parts after cutting.

4. Check the end surface: In the end, the use of the end method will cause a large amount of fine iron powder to be adhered to the front end. Therefore, the cross -sectional area of the dual material must be checked or the burrs are removed according to the line metal to clean the dishes according to the production.

5. Inspection and calibration of extended mold: In order to reduce the incidence of uneven metal stamping, regular inspections and maintenance of extended molds should be checked to maintain the processing stability of the hardware stamping parts. Common manufacturing methods are sampling of side loops and machine processing surfaces (mold corners and convex angles) to check whether there are bond scratches.
