Maintenance of hydraulic parts of CNC bending machine

Regular maintenance should be performed on the relevant hydraulic components of the hydraulic bending machine

      1. After using the newly purchased hydraulic bending machine for one month, check whether there is any deformation in the bends of the oil pipes. If there is any abnormality, they should be replaced. After two months of use, all fittings should be tightened. When doing this work It should be shut down and the system has no pressure.

     2. The hydraulic bending machine cleans the hydraulic components (base plate, valve, motor, pump, oil pipe, etc.) every month to prevent dirt from entering the system, and cleaning agents cannot be used.

     Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be further divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization. According to the movement mode, hydraulic bending machines can be divided into up-moving type and down-moving type.

     What is a bending machine?

     Main classification

     Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization. According to the movement mode, hydraulic bending machines can be divided into up-moving type and down-moving type.

     Structure description

      1. Slider part: hydraulic transmission is adopted, and the slider part is composed of a slider, an oil cylinder and a fine-tuning structure of a mechanical stopper. The left and right oil cylinders are fixed on the frame, the piston (rod) drives the slider to move up and down through hydraulic pressure, and the mechanical stop is controlled by the numerical control system to adjust the value;

      2. Workbench part: controlled by the button box, the motor drives the stopper to move back and forth, and the moving distance is controlled by the numerical control system. The minimum reading is 0.01 mm (the front and rear positions have travel switch limits);

     3. Synchronization system: The machine consists of a mechanical synchronization mechanism composed of torsion shafts, swing arms, joint bearings, etc., with simple structure, stable and reliable performance, and high synchronization accuracy. The mechanical stop is adjusted by the motor, and the numerical control system controls the value;

     4. Stopper mechanism: The stopper is driven by a motor, and the two screw rods are driven to move synchronously through a chain operation. The numerical control system controls the size of the stopper.

About the development trend of CNC bending machine

     Purchase correctly

     Once an improper selection is made when purchasing a bending machine, the production cost will rise, and the bending machine cannot be expected to recover the cost. Therefore, there are several factors that must be weighed in the decision-making process.
