What is the working principle of hydraulic pipe bender? Advantages and disadvantages?

Working principle of hydraulic pipe bender;

The high-pressure oil output by the electric oil pump is sent to the working cylinder through the high-pressure oil pipe, and the high-pressure oil pushes the plunger in the working cylinder to generate thrust, which bends the pipe through the elbow part.

Advantages:

1, the pipe bender adopts touch screen and numerical control module, which is operated in dialogue mode and the program setting is simple and easy;

2, the bed body is stable in structure and not easy to deform;

3. Each file can be set with 16 bending angles, and the memory can store 16 files;

4. All of them have slow positioning function, stable elbow angle and repetition accuracy of 0.1;

5. The error message is displayed on the screen to help the operator eliminate it immediately;

6. Provide self-developed coordinate conversion elbow processing values, and the software can be installed on a desktop computer for editing and calculation.

Disadvantages:

1, large-diameter pipes cannot be formed at one time, and the speed is slow;

2. Pipes with different diameters should have molds with different sizes.
