How to solve the problems of uneven metal surface when precision metal stamping?
Release time:2022-09-17Views:1097

When precision metal stamping, what is the reason for uneven metal surface? If these problems are not solved, it will have a great impact on the appearance and productivity of metal products, resulting in increased costs and other bad consequences. We summarized and formulated some plans to reduce metal indentation In the process of production and processing.


Reasons and solutions for uneven metal surfaces:

1. Inspection and maintenance of plate cleaning equipment: Before production, the metal press needs to be inspected and maintained to make its cleaning more effective. Pay attention to the quality of roller joints and cleaning oil.

Proper hand speed: conduct material testing on parts before manufacturing. Reasonably set the speed of the manipulator and the angle of material to prevent contact with the manufacturing parts and the lower die, and prevent semi-automatic stretching production. When the drawing needle is in the lower die position, the speed of the manipulator is fast, and the burrs will fall on the punch, causing uneven metal indentation.

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

4. Check cut-off surface: damage in cut-off mode will cause a large amount of thin iron powder to stick to the front, so the cross sectional area of the dual-material or the burr cleaning plate must be checked according to the metal of the production line.

5. Inspection and calibration of extension die: In order to reduce the occurrence of uneven metal indentation, the extension die should be inspected and maintained regularly to keep stability. The common manufacturing method is to sample the side ring and processing surface (die angle) to check whether there are adhesive scratches on the convex corner.
