when the diamond mesh is leveled

What should be paid attention to when the diamond mesh is leveled?

1. The diamond-shaped mesh coating and the galvanized steel strip have a flatness of 0.5% when the thickness is not more than 0.70 mm.

2. The diamond mesh usually requires strict control of the flattening rate of the cold-rolled strip for deep drawing.

3. When there is a platform strip, there will be a slip line during the stamping process. When bending into a circle, there will be a tendency of lateral folding, which will result in poor surface quality of the workpiece. Therefore, the flattening process should adopt the corresponding flat elongation to achieve the adjustment. Performance purpose

4. In the process, the diamond mesh has control requirements for the flatness of each steel coil, and the whole material steel coil must have a stable rate.

5, using tin plate, requires a certain strengthening deformation to adjust the strength and hardness, the flat elongation is 1% -3%

6, diamond-shaped net for deep-drawing automotive sheet, because the requirements for restrictions are very low and eliminate the platform, it is generally considered that the best flat elongation range is 0.8% - 1.4%
