2、Working diagram of cnc sheet metal folding machine

Main performance characteristics of CNC sheet metal folding machine

1. All steel plate welding structure, hydraulic transmission, vibration to eliminate stress.

2. CNC sheet metal folding machine adopts advanced integrated hydraulic system with overload protection function and good reliability.

3. The upper tool rest adopts the inward inclined structure, which is convenient for blanking.

Ordinary bending can only realize simple bending function, but cannot realize automatic positioning. CNC bending machine can realize automatic positioning and make bending more efficient.

Factors affecting springback and measures to reduce springback

(1) Mechanical properties of materials

The springback angle is directly proportional to the yield point of the material and inversely proportional to the elastic modulus E. CNC sheet metal folding machine for sheet metal parts with high accuracy requirements, in order to reduce springback, low carbon steel should be selected as far as possible instead of high carbon steel and stainless steel.

(2) The larger the relative bending radius R / T is, the smaller the deformation degree is and the smaller the springback angle is Δα The bigger it is. This is an important concept. When the material properties permit, the fillet of sheet metal bending should be as small as possible, which is conducive to improving the accuracy. In particular, the design of large arcs should be avoided as far as possible.Large circular arc is difficult for production and quality control.
