1. Precision hardware processing Customized surface scratch problem

Reason analysis: ① The surface of the raw material is not smooth. ② The curved radius of the rush is too small. ③ The gap between the bend is too small.

Solution: ① Improve the smoothness of the upper and lower molds. ② Add the bending radius of the mold. ③ Adjust the bending gap

2. The "corrosion pit" and "peeling" on the surface of the curved parts

Cause analysis: Due to the bubbles or rainwater in the plate itself, "peeling" and "corrosion pit" may occur during processing, which is usually difficult to detect with the naked eye and rarely occur.

Solution: Magnetic powder detection can solve this problem (high cost).

3. Bending rebound problem

Cause analysis: In the process of processing the items made of different materials (carbon steel, stainless steel, aluminum alloy), if the equipment programming parameters are adjusted to the same, the rebound of the item will change a lot, or the angle is too small, or the angle is too small, or the angle is too small, or the angle is too small. Or the angle is too large.

Solution: Depending on the curved materials (carbon steel, aluminum alloy, stainless steel), programming high -quality hardware processing equipment is used to select the materials to be processed and adjust the bending angle to solve the rebound problem.

4 Cracking on the surface of the curved molding part

Cause analysis: ① The curved inner radius is too small. ② The direction of the grain of the material is parallel to the curve. ③ The sideways of the bonding of the blank material. ④ The plasticity of the metal is poor.

Solution: ① The cutting particles of the material must be vertically in the direction of bending. ② There must be no steel seal on the surface of the material. ③ The burrs on the opening should be clamped around the material. ④ Choose the right mold for bending operation. Do not use it for precision or rough processing.
