[0023] See also Figures 1 to 5The utility model provides a technical solution: a semicircular tube bending device, including a tube bending device body, the tube bending device body includes a box body 1, a ring seat 2 is fixed on the top of the box body 1, a movable seat 3 is movably installed on the top of the ring seat 2, a movable frame 4 is movably installed on the top of the movable seat 3, a slide groove 5 is opened on the movable frame 4, and a limiting groove 6 is opened on the side of the slide groove 5, a slider 22 is movably installed inside the slide groove 5, a support mechanism 8 is fixedly installed between the slider 22 and the slide groove 5, and the support mechanism 8 is a support spring. When the slider 22 has no extrusion force, the support spring pushes the slider 22 to move in the direction of the fixed plate 9, so that the movable plate 11 and the movable plate 11 are moved together. The distance between the ring seats 2 is increased, which is convenient for the subsequent rotation adjustment of the movable plate 11. The first power mechanism 7 is fixedly installed on the slider 22. The first power mechanism 7 is a DC motor. The DC motor drives the movable plate 11 to complete the rotation adjustment through the output shaft 23. The bottom of the first power mechanism 7 is fixed with a limiting block 21, and the limiting block 21 is movably installed inside the limiting groove 6. A fixed plate 9 is welded to one end of the movable frame 4, and a displacement mechanism 10 is fixedly installed on the fixed plate 9. The displacement mechanism 10 is an electric push rod, which pushes the movable plate 11 to move closer to the position of the ring seat 2, and the semicircular tube is clamped and fixed by the roller 20 or the limiting wheel 24 on the movable plate 11.

[0024] In this embodiment, a movable plate 11 is movably installed at the bottom of the slider 22, an output shaft 23 is installed on the first power mechanism 7, one end of the output shaft 23 is fixed on the movable plate 11, a roller 20 is fixedly installed on one side of the movable plate 11, and a limiting wheel 24 is installed on the other side of the movable plate 11, and the limiting wheel 24 and the roller 20 are both matched with the ring seat 2, and a fixed block 12 and a support block 13 are respectively welded on the top of the box body 1, an extrusion plate 14 is movably installed between the support block 13 and the fixed block 12, a threaded column 15 is rotatably installed on the support block 13, one end of the threaded column 15 is installed on the extrusion plate 14 through a bearing, and the threaded column 15 rotates to push the extrusion plate 14 to extrude and limit the semicircular tube on the fixed block 12, and limit and fix one end of the semicircular tube.

[0025] In this embodiment, an opening 16 is provided on the ring seat 2, and lifting mechanisms 17 are installed on both sides of the opening 16. The lifting mechanism 17 is fixedly installed between the box body 1 and the ring seat 2, and one end of the lifting mechanism 17 is fixedly installed on the movable seat 3. The lifting mechanism 17 is an electric push rod, which pushes the movable seat 3 to move up and down. The up and down movement of the movable seat 3 can complete the clamping and limiting of the pipeline. A second power mechanism 19 is fixedly installed inside the box body 1, and a rotating column 18 is installed on the second power mechanism 19. The rotating column 18 is movably installed inside the opening 16, and one end of the rotating column 18 is fixed on the movable frame 4. A cavity 25 is provided inside the movable seat 3, and the cavity 25 is circular. The movable seat 3 is movably installed on the ring seat 2 through the cavity 25.

The movable frame 4 rotates to bend the pipeline with the ring seat 2 as the fulcrum.

[0026] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, first place one end of the semicircular tube between the fixed block 12 and the extrusion plate 14, rotate the threaded column 15 to push the extrusion plate 14 to move in the direction of the fixed block 12, and the extrusion plate 14 and the fixed block 12 cooperate to complete the clamping and fixing of one end of the semicircular tube. After the clamping is completed, the arc plate on one side of the semicircular tube is installed on the ring seat 2, and the displacement mechanism 10 is started to push the movable plate 11 to move in the direction of the ring seat 2. After the movable plate 11 moves, the roller 20 contacts the flat surface of the semicircular tube, and the second power mechanism 19 is started. The second power mechanism 19 drives the movable frame 4 to rotate around the ring seat 2 through the rotating column 18, and bends with the ring seat 2 as the fulcrum. The roller 20 pushes the semicircular tube to fit with the ring seat 2, thereby completing the bending of the semicircular tube. When it is necessary to When the flat surface of the semicircular tube is the bending point, the displacement mechanism 10 loses the squeezing force on the movable plate 11, and the supporting mechanism 8 pushes the slider 22 to move in the direction of the fixed plate 9, thereby increasing the distance between the movable plate 11 and the ring seat 2, and starting the first power mechanism 7 to drive the movable plate 11 to rotate 180 degrees, and the limiting wheel 24 is matched with the ring seat 2. Under the squeezing of the displacement mechanism 10, the movable plate 11 moves in the direction of the ring seat 2 again, and the limiting wheel 24 contacts the arc surface of the semicircular tube, and the ring seat 2 contacts the plane of the semicircular tube. The limiting wheel 24 is used to bend the semicircular tube with the plane as the bending point.

After the contact, the movable seat 3 realizes the upper and lower limit of the semicircular tube, thereby avoiding the influence caused by the up and down movement when the pipe is bent.
