[0002] A dual-machine linkage CNC bending machine, that is, two bending machines working synchronously, can process large-size workpieces. At this time, a CNC system is required to synchronously control the two bending machines. Currently, only expensive electro-hydraulic synchronous bending machines and their CNC systems have such functions. If a torsion axis bending machine is used, the cost will be much lower.

The material support device of the dual-machine linkage CNC bending machine uses a driving motor to drive the threaded rod to rotate, so that the moving block drives the slider to move up and down, which is convenient for adjusting the height of the material support frame and adapting to different material support requirements. When supporting the material, the positioning plate is used to position the material plate, which improves the practicality. At the same time, the telescopic cylinder is used to push the front end of the material support frame to move, so as to adjust the angle of the material support frame, and when the height of the material support frame is adjusted, the telescopic cylinder is used to push the material support frame to ensure the flatness of the material support frame.
