Description

Technical Field

[0001] This utility model relates to the field of bending machines, and in particular to a pipe bending machine. Background Technology

[0002] A pipe bending machine is a mechanical device used to bend various pipe fittings. It primarily achieves bending by applying external force to induce plastic deformation in the pipe fitting. Hydraulic pipe bending machines utilize high-pressure oil generated by a hydraulic system to drive a hydraulic cylinder, which in turn drives a bending die to bend the pipe fitting. They can provide significant bending force and bend pipe fittings with large diameters and thick walls. However, existing pipe bending machines have limited functionality and require multiple bends at different angles on the same pipe fitting. Furthermore, it is difficult to adjust the bending direction during bending, significantly reducing work efficiency.

[0003] Therefore, it is necessary to provide a pipe bending machine to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a pipe bending machine, which solves the problems of existing pipe bending machines having limited functions, requiring multiple sections of the same pipe to be bent at different angles, and making it difficult to adjust the bending direction during bending, which greatly reduces work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a pipe bending machine, including a base, a motor fixed on the top of the base, and a bending disc fixed on the output end of the motor, with a limit block fixed on the bending disc by a hydraulic cylinder;

[0006] A fixing block is fixed to the top of the base, and a limiting tube is rotatably installed on the fixing block. A fixing frame is fixed to the limiting tube, and a first hydraulic rod is fixed inside the fixing frame. A locking block is fixed to the bottom end of the first hydraulic rod, and a locking hole adapted to the locking block is provided on the limiting tube.

[0007] Preferably, a second hydraulic rod is fixed on the fixing block and on both sides of the limiting tube, and a clamping block is fixed at the output end of the second hydraulic rod.

[0008] Preferably, the bending disc is provided with a first groove, and one side of the limiting block is provided with a second groove that matches the first groove.

[0012] Compared with related technologies, the pipe bending machine provided by this utility model has the following advantages:

[0013] This utility model provides a pipe bending machine. By adjusting the extension length of the pipe, a first hydraulic rod drives a locking block to fix the pipe. Then, a second hydraulic rod is activated to disengage from the limiting tube. The bending direction of the pipe is adjusted using a handle. After adjustment, the second hydraulic rod is activated again to fix the limiting tube. The hydraulic cylinder is then activated again to drive the limiting block to fix the bend of the pipe. Finally, the motor is started, and the bending disc bends the pipe. This invention solves the problems of existing pipe bending machines having limited functionality, requiring multiple bends at different angles on the same pipe, and difficulty in adjusting the bending direction during bending, which greatly reduces work efficiency.
