Precision Sheet Metal Stamping Parts

precision sheet metal stamping parts:
In the production of precision metal stamping parts, it is not only necessary to control the accuracy and accuracy, but also to achieve a smooth and flawless appearance
1. Crushing and scratching of precision metal stamping parts
1. Oil stains and debris on the material belt or mold may cause crushing. It is necessary to wipe off the oil and install an automatic air gun to remove the debris.
2. The surface of the mold is not smooth, and the surface finish of the mold should be improved.
3. The surface hardness of precision metal stamping parts is not enough, and the surface needs chrome plating, carburizing, boronizing and other treatments.
4. Material strain and instability, reduce lubrication, increase compressive stress, adjust spring force.
5. Process the mold for jumping waste.
6. If the product scratches the mold positioning or other places during operation, the mold positioning needs to be modified or lowered, and the operators should be educated to handle it with care.
2. The outer surface of precision metal stamping parts is scratched after bending
1. The surface of the raw material is not smooth, clean and level the raw material.
2. If there is waste in the forming blocks, remove the waste between the blocks. .
3. The forming block is not smooth, and the forming block is electroplated and polished to improve the smoothness of the convex and concave dies.
4. The bending radius R of the punch is too small, increase the bending radius of the punch
5. The bending gap of the mold is too small, adjust the bending fit gap of the upper and lower molds.
6. The concave mold forming block is formed by adding rollers.
