CNC bending machine use

CNC bending machine use process needs to pay attention to several points

1. Bending machine mold 88 ° why can press out 90 °. Because the metal plate has a certain elasticity, ordinary cold-rolled plate mold angle 88 ° on it, but stainless steel only need 86 °, some elasticity only 83 ° on the line, aluminum hardness is low, elasticity is small, mold angle must be 90 °, so you do not understand, in addition the angle size of the mold is mainly determined by the elasticity of the plate, bending pressure size is also able to affect the angle of the workpiece.

2. General bending machine tooling quenching hardness is how much. Heat treatment of bending machine tooling is HRC47±2 °. Hardness is too high easily lead to mold fracture. So, not high hardness is durable. Bending machine mold hardening hardness can reach how much, this also depends on the bending machine mold material and bending machine mold style to decide. But not high hardness is good to use. The general reasonable hardness of HRC47 ± 2 °

3. In bending acute angle, or press dead angle, should be selected on 30 degrees, first bending acute angle, after pressing dead edge. In bending R angle, should be selected with R upper die and R lower die for.

4. In the bending of longer workpieces, it is best not to use segmented mold, reduce the joint knife indentation, and it is best to use a single slot, because the single slot of the lower die V slot outer angle R large, not easy to produce bending indentation.

5. In the bending hardness or plate material is too thick products, the use of 103 # and 116 # on the mold is strictly prohibited, easy to damage the mold, not allowed to use the mold to bend steel bars or other cylindrical products.

Finally, the bending machine mold used to put back on the mold rack in a timely manner, and put according to the logo, often clean the dust on the mold, the next time to use more accurate.
