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!
Question 1 : The cause of the deformation of the hole caused by the bending of the sheet metal processing:
When the elastic bending is performed and the hole is positioned, the outer side of the curved arm is pulled due to the friction of the surface of the concave mold and the outer surface of the workpiece, and the positioning hole is deformed.
Solution:
1, using shape bending
2, increase the pressure of the top plate
3. Add a plaque pattern on the top plate and CNC sheet metal processing to increase the friction to prevent the part from slipping during bending.
Question 2 : Reasons for the thinning of the curved surface of the sheet metal processing:
1, the die fillet is too small
2. The clearance between the convex and concave molds is too small
Solution:
1. Increase the radius of the die radius
2. Correct the gap between the convex and concave molds
Question 6: Reasons for the bulging or unevenness of the sheet metal processing parts:
1.When bending, the outer surface of the material is pulled and deformed in the circumferential direction. In Shenzhen Tingshun Electromechanical, the inner surface is pressed in the circumferential direction to produce elongation deformation, so that the curved end face appears in the bending direction to cause bulging.
Solution:
1. The stamping die should have sufficient pressure after the stamping
2. Make a concave corner radius corresponding to the fillet of the part
3, increase the process improvement
Above is the sheet metal processing bending process encountered problems and solutions.
