The outer circle of the positioning pin 13 is correspondingly installed with the inner wall of one group of pin holes 12. The matching arrangement of the positioning pin 13 and the plurality of pin holes 12 can position the bending wheel disc 55 through the adjusting plate 521, so as to meet the operation requirements for different bending degrees of the steel pipe. A guiding frame 59 is arranged between the two groups of positioning plates 531. A pin hole five is opened on the guiding frame 59. A plug pin 11 is arranged in the pin hole five.

The arrangement of the plurality of adjusting holes 14 enables the operator to adjust the position of the guiding frame 59 through the plug pin 11, so that the guiding frame 59 can guide the bending forming of the steel pipe conveyed over.Below the lower set of positioning plates 531, there is an angle dial 510. The installation end of the angle dial 510 is provided with an installation hole, and the inner wall of the installation hole fits with the outer circle of the fixed column 9. The setting of the angle dial 510 enables the operator to accurately adjust the bending angle during the steel pipe bending operation, thereby improving the accuracy of the steel pipe during bending and forming. The angle dial 510 is correspondingly installed with the fixed column 9 through the installation hole, and the installation end of the angle dial 510 is fixedly connected to the fixed column 9. On one side of the bending wheel disc 55, there is a connecting block 56. One side of the connecting block 56 is correspondingly installed with one side of the bending wheel disc 55, and one side of the connecting block 56 is fixedly connected to the bending wheel disc 55. A bending frame 57 is arranged on the connecting block 56. An adapter seat 58 is arranged inside the bending frame 57. The inner side of the adapter seat 58 fits with the upper and lower sides of the connecting block 56. Corresponding bolt holes four are opened on the connecting block 56, the bending frame 57, and the adapter seat 58. A fixing pin 10 is arranged in the bolt hole four. The fixing pin 10 is fixedly connected to the connecting block 56, the bending frame 57, and the adapter seat 58 respectively through the bolt holes. On one side of the adapter seat 58, there is a pointer 511. The installation end of the pointer 511 is correspondingly installed with one side of the adapter seat 58. One end of the pointer 511 is fixedly connected to one side of the adapter seat 58. When the pointer 511 is in the installed state, the top of the pointer 511 points to the scale on the angle dial 510. The setting of the pointer 511 can cooperate with the angle dial 510 to enable the operator to more conveniently view the scale, thereby adjusting the forming bend of the steel pipe. The setting of the bending quick adjustment assembly 5 enables the operator to adjust according to the operation requirements, so as to meet the processing and forming requirements of steel pipes with different bends. At the same time, the overall structure is simple. Through the setting of the cylinder 51, it is convenient for the operator to quickly adjust the bending wheel disc 55 through the positioning pin 13, and at the same time, it cooperates with the bending frame 57 and the guide frame 59 to quickly and accurately bend and form the steel pipe, improving production efficiency.

[0024] In this embodiment, when the operator needs to perform a bending and forming operation on a steel pipe, the operator first adjusts the guide frame 59 on the positioning plate 531 through the bolt 11 to make the guide frame 59 meet the operation requirements for the bending angle of the steel pipe. At the same time, the operator pulls out the positioning pin 13 from the pin hole 12, and then the operator rotates the bending wheel disc 55, so that the bending wheel disc 55 drives the bending frame 57 to rotate and adjust through the connecting block 56, so that the inner cavity of the bending frame 57 corresponds to the inner wall position of the guide frame 59. Then, the operator guides one end of the steel pipe to be bent through the guide frame 59 through the feeding mechanism and passes it through the bending frame 57. Then, the operator inserts the positioning pin 13 into a set of pin holes 12 on the adjusting plate 521 and the bending wheel disc 55. Then, the operator energizes the air cylinder 51 to operate, and the air cylinder 51 operates to push the adjusting frame 52 to move. The movement of the adjusting frame 52 drives the bending wheel disc 55 to rotate under the action of the positioning pin 13. The rotation of the bending wheel disc 55 drives the pointer 511 to rotate through the connecting block 56 and the connecting seat 58, so that the top of the pointer 511 rotates and indicates the scale on the angle scale 510. When the pointer 511 moves to the required angle scale, the air cylinder 51 stops operating, thus completing the bending and forming operation of the steel pipe.

[0025] The above specific embodiment is only a preferred embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
