[0002] Pipe processing is a technical process for processing pipe materials. Its main purpose is to process various pipe fittings into shapes that meet requirements according to the requirements. Among them, a semi-automatic bending machine is a frequently used pipe bending device. The semi-automatic pipe bender realizes the bending and forming of pipes by controlling the bending wheels on the machine. For pipes with different diameters, wall thicknesses and materials, the rotation speed of the bending wheels can be controlled by adjusting the speed control device on the machine, so as to realize the processing of different bending radii and angles. The pipe bender usually also installs guide wheels that cooperate with the bending wheels to work. The guide wheels can accurately control the moving direction of the bent pipe and ensure that the bent pipe bends along a predetermined path. This is mainly achieved by the rotation of the guide wheels and the force applied when contacting the bent pipe, so as to ensure the accuracy and consistency of the pipe bending process.

[0025] Referring to Figure 4 , the connecting component 4 includes a pulling rod 8. The pulling rod 8 is arranged on the right side of the connecting block 3. The left side of the pulling rod 8 extends and penetrates into the inner wall of the connecting block 3. A pulling block 9 is fixedly connected to the left side of the pulling rod 8.

[0026] With the above solution: By setting the pulling rod 8, when the pulling rod 8 is pulled, the pulling rod 8 can move and drive the pulling block 9 to move.

[0027] Referring to Figure 4 , the top of the pulling block 9 is fixedly connected to the bottom of the left side of the pulling rod 8. The bottom parts of the front and rear sides of the pulling block 9 are respectively fixedly connected to movable rods 10. The outer surfaces of the two movable rods 10 are respectively sleeved with movable arms 11.

[0028] Adopt the above solution: By setting the pulling block 9, the pulling block 9 can drive two movable rods 10 to move simultaneously during the movement process, so that the two movable rods 10 drive the rotation of two movable arms 11 respectively when moving.

[0029] Reference Figure 4 , the middle parts of the two movable arms 11 are respectively rotationally connected to the inner wall of the connecting block 3 through rotating shafts. Activity grooves 12 are formed on the surfaces of the two movable arms 11. The inner walls of the two activity grooves 12 are respectively in contact with the surfaces of the two movable rods 10. One ends of the two movable arms 11 far away from the pulling rod 8 are respectively fixedly connected with moving rods 13. Moving arms 14 are respectively arranged on the sides of the two moving rods 13 away from each other.

[0030] Adopt the above solution: By setting the movable arms 11, the two movable rods 10 drive the rotation of the two movable arms 11 by respectively pressing the two activity grooves 12 during the movement process, so as to make the two moving rods 13 drive the movement of the two moving arms 14 respectively.

[0035] The working principle of the present utility model:

[0036] When in use, when the guide wheel 501 needs to be replaced, the pulling rod 8 is pulled, the pulling rod 8 moves and drives the pulling block 9 to move, and the pulling block 9 drives the two movable rods 10 to move at the same time. When the two movable rods 10 move, they squeeze the movable grooves 12 respectively to drive the two movable arms 11 to rotate respectively. When the two movable arms 11 rotate, they drive the two movable rods 13 to move respectively. The two movable rods 13 move and squeeze the surfaces of the two movable arms 14, so that the two movable arms 14 slide away on the surface of the sliding rod 7, and at the same time squeeze the fixing spring 15 and drive the two fixed arms respectively. 16 slides away on the surface of the sliding groove 6, so that the two fixed grooves 17 are separated from the positioning block 5, and then the positioning block 5 is slid and removed from the other end, and the guide wheel 501 is replaced. After completion, the positioning block 5 is slid back into the positioning groove 105, and the pulling rod 8 is repeatedly pulled to move the two fixed arms 16 away, and one side of the positioning block 5 is slid into the two fixed arms 16, and the pulling rod 8 is released to allow the fixing spring 15 to push the two movable arms 14 to move closer, and the two fixed arms 16 respectively fix the positioning block 5 through the two fixed grooves 17 to complete the installation of the positioning block 5.

[0037] In summary: the pipe processing bending machine, through the cooperation of the main body 1, the movable seat 2, the connecting block 3 and the connecting assembly 4, solves the problem that the guide wheel of the semi-automatic pipe bending machine will gradually wear out over time and with increased use, resulting in a decrease in its guiding performance, which may cause the pipe to deviate from the predetermined path during the bending process, affecting the accuracy and quality of the bent pipe.
