The screw rod 10 is connected to the moving block 11 through an external thread, so that the moving block 11 can achieve precise linear movement under the rotation of the screw rod 10. As the two screw rods 10 rotate, the two moving blocks 11 begin to move relative to each other.

[0029] During the loading process, first, the pipes are placed in order inside the unloading rack 4. Then, the second motor 19 is started. When the motor is started, the threaded rod 20 fixed at its output end begins to rotate. The external threads of the threaded rod 20 are tightly connected with the threaded block 21 to ensure that the threaded block 21 can be driven to move during the rotation process. As the threaded rod 20 rotates, the threaded block 21 begins to move along the preset track. At this time, the externally fixed mounting rod 22 also moves together. The movement of the mounting rod 22 moves the externally fixed moving plate 23, and the movement of the moving plate 23 moves the pipes placed on the upper part. When the uppermost pipe moves to the middle of the two auxiliary blocks 30, the operation of the second motor 19 is suspended. At this time, the electric push rod 2901 is started, and the push plate 2902 is fixed at the output end of the electric push rod 2901. The push plate 2902 can ensure that there is no sliding or tilting when pushing the pipe.

The electric push rod 2901 moves with the push plate 2902 fixed at the output end. The pipe in the middle of the two auxiliary blocks 30 is pushed to the middle of the two arc-shaped clamping plates 15 through the movement of the push plate 2902. In this way, the automatic loading operation is realized during the pipe bending process. There is no need for the operator to manually load the pipe, which can effectively avoid accidents caused by manual handling of heavy pipes or operating errors, thereby improving work safety.
