Cnc hydraulic press brake is a kind of can be carried out on the thin plate bending machine, the structure mainly includes the bracket, workbench and clamping plate, workbench on the scaffold, workbench consists of base and the clamp, the base through the hinge is connected with the clamping plate, the base is composed of shell, the coil and plate, coil placed inside the shell of the sag, the depression at the top of the cover plate. When used, the wire is energized to the coil, and after energized, the pressure plate produces gravity, so as to achieve the clamping between the pressure plate and the base plate. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece can be processed on the side wall, the operation is also very simple.
The large CNC bending machine comprises a bracket, a workbench and a clamping plate, the workbench is arranged on the bracket, the workbench is composed of a base and a clamping plate, the base is connected with the clamping plate through a hinge, the base is composed of a shell, a coil and a cover plate, the coil is placed in the depression of the shell, the top of the depression is covered with a cover plate.
When used, the wire is energized to the coil, and after energized, the pressure plate produces gravity, so as to achieve the clamping between the pressure plate and the base plate. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece can be processed on the side wall. Large CNC bending machine can be replaced by bending machine die, so as to meet the needs of a variety of workpiece.
Bending machine: what is the main structure and function of bending machine?
1, all steel welded structure, with enough strength and rigidity;
2. Hydraulic upward transmission, the cylinder at both ends of the machine tool is arranged on the slide block, and directly drives the sliding work;
3, slider synchronization mechanism adopts torsion shaft forced synchronization;
4, mechanical block structure, stable and reliable;
5, slider stroke motor quick adjustment, manual fine tuning, counter display;
6, oblique wedge deflection compensation mechanism to ensure higher bending accuracy.
1, slide block part: hydraulic transmission, the slide block part is composed of slide block, oil cylinder and mechanical block fine tuning structure. The left and right cylinders are fixed on the frame, and the piston (rod) drives the slider up and down through hydraulic pressure, and the mechanical block is controlled and adjusted by the NUMERICAL control system.
2, the work table part: operated by the button box, so that the motor drives the stopper frame to move before and after, and controlled by the NUMERICAL control system to move the distance, its minimum reading is 0.01 mm (before and after the position are travel switch limit);
3, synchronization system: the machine is composed of torsion shaft, swing arm, joint bearing and other mechanical synchronization mechanism, simple structure, stable and reliable performance, high synchronization accuracy. The mechanical block is adjusted by the motor, and the numerical control system controls the value;
4, stopper mechanism: stopper adopts motor drive, drives two screw synchronous movement through chain operation, numerical control system controls the size of stopper.
