Hydraulic digital bending machine is a machine tool that can display feed parameters through a digital tube/display screen, usually used for bending sheet metal materials.

Composition of hydraulic digital bending machine:

Sliding block

Sliding block part: It adopts hydraulic transmission, and the sliding block part is composed of a sliding block, an oil cylinder, and a mechanical stopper fine adjustment structure. The left and right oil cylinders are fixed on the frame, and the piston (rod) drives the slider to move up and down through hydraulic pressure. The mechanical stopper is controlled and adjusted by the numerical control system.

Workbench

Workbench section: Operated by a button box, the motor drives the material rack to move forward and backward, and the distance of movement is controlled by the CNC system, with a small reading of 0.01 millimeters (both front and rear positions have travel switch limits).

Synchronization system

Synchronization system: Unlike ordinary bending machines, this machine uses servo valves and hydraulic devices such as grating rulers to form a closed-loop circuit, thereby controlling various actions of the bending machine.

Material blocking mechanism

Material blocking mechanism: The material blocking is driven by a motor, and the two screw rods are synchronously moved through chain operation. The CNC system controls the size of the material blocking.

Hydraulic digital bending machine supporting system:

1. Taiwanese Delta touch screen Chinese CNC system (or Dutch DELEM CNC system): It has one-way and two-way positioning functions, can adjust screw clearance, has retreat material selection function, avoids interference between material blocking device and workpiece, reduces wear, improves positioning accuracy, and has automatic or manual search reference point function. Equipped with power-off position memory function, it provides on-site protection for parameters, positions, and programs. Equipped with multi-step machining programming function, it can achieve multi-step dynamic operation, complete one-step machining of multi-step parts, and improve production efficiency. One axis servo motor automatically controls the up and down stroke adjustment of the slider, while the other axis servo motor controls the rear stop material. Select Taiwan ABBA ball screw guide pair.

2. The main sealing components of the oil cylinder are produced by the Japanese company Huarka.

3. The main components inside the electrical box are produced by Schneider in France.

4. All hydraulic systems are controlled by plug-in valves.

5. The hydraulic pump adopts aerospace standard low-noise internal gear pump.

6. The whole machine is welded from steel plates, and the welding parts are subjected to vibration stress. The machine has high strength and good rigidity, and the frame can maintain stability and deformation for a long time.

7. The main oil cylinder piston of the machine tool adopts aerospace technology - surface nickel phosphorus treatment, and its hardness can reach HRC60 or above. The guide sleeve that moves relative to the piston adopts a zinc based wear-resistant alloy with self lubrication, which can keep the oil cylinder in good working condition for a long time.

8. Adopting torsion axis synchronization and mechanical blocking, reliable, economical, and high-precision.

9. The upper mold is equipped with a winding compensation mechanism.
