CNC Bending Machine is a machine that uses the equipped mold (general purpose or special mold) to bend the metal sheet under cold state into various geometric cross-section shapes of the workpiece.
It is a sheet metal forming machine designed for cold-rolled sheet metal processing, widely used in automobile, aircraft manufacturing, light industry, shipbuilding, container, elevator, railway vehicles and other industries of sheet metal bending processing.

 

The bending machine can be said to be a kind of instrument that can bend thin plates, and now there are different classifications for its nature, and the overall composition is relatively simple.

The bending machine can be divided into three types: manual bending machine, hydraulic bending machine, CNC bending machine.

1, Manual bending machine: it can be divided into two types, mechanical manual bending machine and electric manual bending machine.

2, Hydraulic bending machine:

(1) According to the synchronization method, it can be divided into three types: torsional axis synchronization, machine-hydraulic synchronization and electro-hydraulic synchronization.

(2) According to the mode of movement is divided into: up-moving type and down-moving type two.

Description of the bending machine structure

1, The slider part: mainly composed of the slider, cylinder and mechanical block fine-tuning structure, the bending machine slider around the cylinder is fixed on the frame, and the piston is driven by the hydraulic way to move up and down.

2, The workbench part: it is controlled by the button box, which can make the motor drive the stop frame to start moving back and forth, and the moving distance is controlled by the numerical control system.

3, Synchronous system: this part is a synchronous mechanism composed of torsion shaft, joint bearing, swing arm and other frames, because the overall structure is relatively simple, so the performance is stable and reliable, synchronization accuracy is relatively high.

4, Stop mechanism: the use of motor drive, specifically through the chain operation to drive the synchronous movement of the two screw, the CNC system of the bending machine is to control the size of the stop.
