In the process of sheet metal processing and production, we will encounter various problems. Below we summarize some problems encountered in the process of sheet metal processing and bending and the solutions!
What are the sheet metal processing bending processes and solutions?
Question 1: The bending edge of sheet metal processing is not straight and the size is unstable:
1. The design process does not arrange the pressing line or pre-bending
2, material pressure is not enough
3, convex and concave mold rounded wear asymmetry or uneven bending force
4, the height is too small.
Solution:
1. Designing the pressing line or pre-bending process
2, increase the pressing force
3, convex and concave mold gap uniform, rounded polished
4, the height size can not be less than * small limit size
Question 2: Reasons for the scratch on the outer surface of the sheet metal processing workpiece after bending:
1. The surface of the raw material is not smooth
2. The bending radius of the punch is too small
The bending clearance is too small. Solution:
1. Improve the smoothness of the convex and concave mold
2, increase the bending radius of the punch
3, adjust the bending gap
Question 3: The reason why the bending angle of sheet metal processing has cracks:
1. The inner radius of the bend is too small
2. The material grain direction is parallel to the bending line
3, the burr side of the blank is outward
4, poor metal plasticity
Solution:
1. Increase the bending radius of the punch
2, change the blanking layout
3, the burr changed to the fillet in the workpiece
4. Annealing or using soft materials
Tomorrow we will continue to share the problems and solutions encountered during the fabrication of sheet metal parts.
