[0002] A pipe bender is a mechanical equipment used to process metal pipes. Its main function is to bend straight pipes into various shapes of bends. A pipe bender is usually composed of a frame, a pipe bending mold, a hydraulic system, an electrical system, etc. The working principle of a pipe bender is to put a straight pipe into a pipe bending mold and apply force through the hydraulic system to bend the pipe into the desired angle and shape.

[0003] When the existing pipe bending machine is in use, the straight pipe material is placed in the pipe bending mold, and the force is applied by the hydraulic system to bend the pipe into the required angle and shape. Since the angle of the existing pipe bending machine changes after bending, the pipe material is easily stuck on the bending block, and manual material picking and connecting is required. However, manual material picking and connecting is time-consuming and labor-intensive, and affects the production efficiency of the pipe bending machine. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the pipe bending machine needs to buffer the material feeding, by starting the extension mode of the hydraulic telescopic rod, the output end of the hydraulic telescopic rod pushes the bending block, the stop block, the positioning rod, the second spring and the push rod to move, and the push rod is gradually squeezed toward the inside of the bending block through the outer wall of the bottom end of the pipe. At the same time, the push rod pushes the second spring to compress and deform. After the push rod moves to the bottom end of the pipe, the second lifting rod drives the stop block to separate from the pipe, and the second spring loses the limit and resets. The second spring pushes the push rod to move, and the push rod pushes the pipe to separate from the bending block. The pipe falls into the collecting pool due to gravity, and the pipe after bending is collected through the collecting pool. The pipe and the bending block are buffered and separated by the push rod, so that the pipe processed by the pipe bending machine is easy to automatically feed, thereby effectively improving the efficiency of the entire production process.

[0013] 2. When the pipe bending machine needs to be automatically loaded, the pushing block is pushed to move by the electric pushing rod, and the pushing block pushes the pipe material under the material box to move. The movement of the pipe material pushes the stop frame to descend, so that the stop frame enters the inner side of the base. At the same time, the stop frame pushes the first spring to compress and deform, and the electric pushing rod continuously pushes the pushing block and the pipe material to move, so that the pipe material moves to one side of the pushing frame. By setting the material box, the electric pushing rod, the pushing block, the stop frame and the first spring, the pipe bending machine can be automatically loaded, reducing the time and labor cost of manual loading, thereby greatly improving production efficiency, reducing accidents and injuries that may be caused by manual operation, and ensuring the safety of production operations.
