The cnc tube bender adopts touch screen and numerical control module for dialog operation. Programming is simple and easy. The structure of the bed is stable, and it is not easy to deform. Each file can set 16 bend angles, and the memory can store 16 sets of files. With slow positioning function, the angle of the bent pipe is stable, and the repeatability is ± 0.1 °. Error messages are displayed on the screen to help the operator eliminate them immediately. Provide the coordinate conversion elbow processing value developed by ourselves. The software can be installed on a desktop computer for editing and calculation.

The upper tool rest of the CNC 3D pipe bending machine swings around a fixed axis during the cutting process. Through the lever action, the fulcrum has less force, which can improve the life of the cutting edge and the life of the machine. The whole machine has a compact structure and can infinitely adjust the stroke of the upper tool post, which greatly improves the work efficiency. So what are the performance and characteristics of cnc tube bending?

1. Frame: Frame-shaped structure welded by steel plate, with outstanding rigidity and stability. The two-cylinder equipment is fixed on both sides of the frame, and drives the upper tool post to swing up and down with the support shaft as the center. An auxiliary knife holder is provided on the work surface, which is convenient for minor adjustment of the lower blade. Feeding steel balls are installed on the workbench panel to facilitate the pushing of the sheet.

2. Pressing equipment: It consists of a set of pressurizing oil cylinders on the front cross beam of the equipment. After the pressurizing oil cylinder enters the pressurizing oil, the pressurizing head is pressed down after defeating the tension of the tension spring. After the cut is completed, it is reset by the tension of the spring. The size of the pressing force increases or decreases with the thickness of the sheet being cut.

3. Front and back material: The front material is placed on the work surface, and the value is indicated with a ruler. The back stop is placed under the horizontal plate of the upper knife holder and moves up and down with the upper knife holder. The adjustment of the back gauge is driven by the motor and reducer. Press the adjustment button "+" or "-" on the operation panel to reach the adjustment of the front and rear orientation of the back gauge. The orientation value of the backgauge is displayed by a digital display installed on the upper left of the front crossbeam of the machine.

4. Hydraulic system of cnc bending machine: It consists of plunger pump, valve group, auxiliary pipe and so on. The hydraulic valve adopts the superimposed valve series, which has low noise, smooth operation, simple pipeline installation, convenient maintenance and good safety performance.

5. Electrical control system: The equipment electrical control system uses brand-name products for easy operation and repair. Power supply 380V / 50Hz. The main switch has short-circuit maintenance and overload maintenance functions of the main motor.

Compared with pendulum hydraulic pipe bender, hydraulic pipe bender has the following advantages:

1. Shear angle can be adjusted. The price of hydraulic pipe bender can choose a balance between plate torsion and shear force, and can be adjusted briefly according to the actual situation.

2. The upper and lower knifes move in parallel, the shearing force is concentrated, and the amount of blade wear is relatively small. There is no sliding friction on the piston rod of the cylinder, and there will be no wear and tear of the ball head.

3. The gap adjustment is simple. The gap conditioning equipment is a three-point lever structure, which is convenient and labor-saving for proper conditioning. The upper and lower blades are rectangular and available on all four sides.

4. The throat is easy to deepen, and the deepest can be increased to about one meter.
