Hydraulic system working principle of pipe bending machine

Working principle of hydraulic system of hydraulic pipe bending machine

The hydraulic system of the hydraulic pipe bending machine consists of 5 hydraulic cylinders and 2 hydraulic motors.
5.1. When bending the pipe, the main clamping cylinder shall always ensure that the pipe is fixed by clamping device and above the rotating arm, and ensure that the pipe is bent according to the predetermined radius;
5.2 the guide clamping cylinder ACTS as an auxiliary clamping tube, with both guiding and supporting functions;
5.3. The propulsion cylinder provides power for the pipe bending machine when the pipe bending is carried out;
5.4. When the auxiliary clamping cylinder is in the bending process, the bending pipe shall be fixed on the trolley to prevent the pipe from vibration during the pushing;
5.5. The positioning clamping cylinder locates the main clamping head on the guide rail of the rocker arm to prevent it from moving due to the force in the work;
2.1 positioning the hydraulic motor to realize the movement of the worktable;
2.2 the reset motor resets the rocker arm at the end of the bend.
In the hydraulic system of pipe bending machine, bending the clamp cylinder, cylinder, auxiliary clip to guide cylinder, promoting and positioning clamping cylinder adopts hydraulic ChanXiangSuo close valve, reduce the pressure loss, to ensure that in the process of pipe bending clamping, bending action and reliable.
