Problem one: the bending edge is not straight and the size is unstable


The reason:

1. The design process does not arrange pressing lines or pre-bending

2. The material pressure is not enough

3. Convex and concave die fillet wear asymmetry or uneven bending force

4. The height size is too small

 

Solutions:

1. Design pressing line or pre-bending process

2. Increase the pressure

3. convex and concave die clearance uniform, rounded corner polishing

4. The height size can not be less than the small limit size


Problem two: the workpiece after bending external surface abrasion

 

The reason:

1. The surface of the raw material is not smooth

2. Punch bending radius is too small

3. The bending gap is too small


Solutions:

1. Improve the finish of the convex and concave die

2. Increase the bending radius of the punch

3. Adjust the bending clearance

 

Problem three: bending Angle crack


The reason:

1. Bending radius is too small

2. The material grain is parallel to the bending line

3. The burr of the blank faces outwards

4. Poor metal plasticity

 

Solutions: 

1. Increase the bending radius of the punch

2. Change the blanking layout

3. Burr is rounded in the workpiece

4. Annealing or soft materials


Problem four: hole deformation caused by bending
