One-stop solution for Sheet Metal Fabrication & CNC Machining - Bergek CNC
Sheet metal bending, as a part of the sheet metal process, is actually the most important part. For the most part of the process requirements, many factories can't pick out anything wrong with the bending step, feel able to meet the bending Angle of 90 degrees on the line, a few degrees more or less can be used to make up for the subsequent welding, but I do not know because of this "meet" so that the bending process has the great potential can be tapped. Today szBERGEK producer sorted out the common problems and solutions of the sheet metal bending process for everyone to learn.
Over the years, Bergek CNC has been offering customers high-quality products and efficient after-sales services with the aim of bringing unlimited benefits for them. custom metal parts Bergek CNC is a comprehensive manufacturer and supplier of high-quality products and one-stop service. We will, as always, actively provide prompt services such. For more details about our custom metal parts and other products, just let us know.Its huge market prospects have helped Bergek CNC attracted more and more customers in the industry.
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
