[0022] See also Figure 1 and Figure 2 It can be seen that when the rotating motor 602 is started, the output end of the rotating motor 602 drives the screw rod 603 to rotate. Since the mounting block 604 is threadedly connected to the screw rod 603, and the mounting block 604 is slidingly connected to the support frame 601, the mounting block 604, the support shaft 605 and the bending wheel 5 move vertically downward, so that the bending operation of the pipe can be achieved through the cooperation of the bending wheel 5 and the support wheel 4.

[0023] See also Figure 1 , Figure 2 and Figure 3 It can be seen that one side of the support wheel 4 is slidably connected to the first movable wheel 9, and one side of the bending wheel 5 is slidably connected to the second movable wheel 10. The inner sides of the support wheel 4 and the bending wheel 5 are both provided with an adjusting mechanism 8, and the adjusting mechanism 8 is composed of a threaded column 801, a threaded barrel 802, a rotating part 803, a limit frame 804 and an annular groove 805.

[0026] See also Figure 1 and Figure 2 It can be seen that when the driving motor 702 is working, the output end of the driving motor 702 drives the threaded rod 703 to rotate. Since the threaded rod 703 is threadedly connected to the support frame 701, and the support frame 701 and the support frame 601, the connecting block 704 and the support block 705 are all rotatably connected through a hinge seat, the distance between the threaded rod 703 and the support frame 701 can be adjusted, so that the support shaft 605 and the bending wheel 5 can be supported and reinforced through the cooperation of the support frame 701, the threaded rod 703, and the support block 705, so as to prevent the support shaft 605 from tilting upward at a certain angle due to long-term excessive force and affecting the subsequent normal use, and at the same time, the service life of the pipe bending machine can be extended.

[0027] See also Figure 1 and Figure 2 It can be seen that a sliding frame 3 is slidably connected in the mounting groove at the top of the base plate 1, and a cylinder 2 is installed between the sliding frame 3 and the mounting groove.

[0029] The working principle of the pipe bending machine with a reinforced structure described in the utility model is as follows: when in use, the distance between the two support wheels 4 is adjusted by extending or contracting the cylinder 2, and then the required pipe is placed on the support wheel 4. At this time, the rotating motor 602 and the driving motor 702 are started, so that the output end of the rotating motor 602 drives the screw rod 603 to rotate, and at the same time, the mounting block 604, the support shaft 605 and the bending wheel 5 are moved vertically downward, so that the bending operation of the pipe can be achieved through the cooperation between the bending wheel 5 and the support wheel 4. In this process, the output end of the driving motor 702 drives the threaded rod 703 to rotate, so that the distance between the threaded rod 703 and the support frame 701 can be adjusted, so that the support frame 701, the threaded rod 703, and the support block 705 can be used to cooperate to support and reinforce the support shaft 605 and the bending wheel 5, so as to prevent the support shaft 605 from tilting upward at a certain angle due to long-term excessive force and affecting subsequent normal use.
