[0002] In the industrial manufacturing process, various pipe fittings are required, and at the same time, the pipe fittings need to be bent into the desired angles according to requirements, and a pipe bending device is needed. In the process of using the existing pipe bending device, the pipe to be processed needs to be placed on the top of the device, and by pushing the pipe, the bending piece generates pressure on the pipe to achieve the effect of bending the pipe. For example, a pipe bending device is described in the patent with the publication number CN220144569U.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, as Figures 1 - 6As shown in the figure, a pipe bending device for convenient feeding includes a mounting base 100. A support assembly is provided at the lower end of the mounting base 100. The support assembly includes legs 101 provided at the corner positions of the mounting base 100. A fixed foot plate is provided at the lower end of each leg 101, so that the mounting base 100 can be suspended. Here, the legs 101 can be replaced with lifting rods to adjust the height of the mounting base 100 for the operation of different people. A rotating shaft 502 is provided at one end of the mounting base 100. At least two support roller groups 503 for supporting the pipe fitting A are provided on the rotating shaft 502. An annular groove surface matching the pipe fitting A is provided on the outer circular surface of each support roller group 503 to increase the contact area with the surface of the pipe fitting A, so as to improve the bending effect. Here, the diameters of different support roller groups 503 are different to switch positions to bend pipe fittings A with different diameters, eliminating the limitations of traditional equipment bending. The end of the rotating shaft 502 is connected to an adjusting member for adjusting its height. The height of the support roller group 503 is adjusted through the adjusting member to adapt to pipe fittings A with different diameters. A downward pressure limiting member for pressing down the upper end of the pipe fitting A is also provided at the end of the mounting base 100. A bending driving assembly 400 for driving the pipe fitting A to be pressed down so that the pipe fitting A bends along the surface of the support roller group 503 is also provided on the rotating shaft 502. A central notch 102 is provided at the center position of the upper end of the mounting base 100. A guiding side plate 104 is provided on the mounting base 100 on one side of the central notch 102. A feeding assembly 300 for providing the pipe fitting A is provided on the other side of the central notch 102. A pushing assembly for pushing the pipe fitting A is provided at the upper end of the central notch 102, so that the pipe fitting A can be quickly and continuously transferred to the bending position to improve the bending efficiency;

[0035] The pushing assembly includes a pushing plate 200 slidably provided on the upper end of the mounting base 100, a pushing screw 202 whose one end is rotatably connected to a fixed block at the lower end of the mounting base 100, and a threaded slider 203 threadedly provided on the pushing screw 202 and connected to the lower end of the pushing plate 200. The other end of the pushing screw 202 is connected to a pushing motor 201 for driving its rotation. In this way, the pushing motor 201 can drive the threaded slider 203 to rotate relative to the pushing screw 202. Under the action of the thread, the threaded slider 203 will slide along the lower end of the mounting base 100, thereby providing power for the pushing of the pushing plate 200. A tapered notch is provided at the end of the pushing plate 200 to match the end of the pipe fitting A to ensure the smoothness of the pushing.

[0036] The feeding component 300 includes a loading frame 301 for storing pipe fittings A. The loading frame 301 is inclined, and a plurality of pipe fittings A are cached inside the loading frame 301. At the notch position at the lower end of the loading frame 301, there is a blocking partition 304 corresponding to the guiding side plate 104. The blocking partition 304 is connected with a lifting push rod 303 for driving it to move up and down. The lifting push rod 303 is connected to the mounting seat 100 through a positioning bracket 302. In this way, the pipe fitting A can be blocked by the blocking partition 304. After bending one pipe fitting A, the lifting push rod 303 can drive the blocking partition 304 to move upward, so that the pipe fitting A at the end slides down to the position of the central notch 102, facilitating the realization of continuous feeding.

[0037] Further, on the mounting seat 100 near the downward pressing limiting member, there is an induction heating ring 103 facilitating the passing of the pipe fitting A. The induction current generated by the induction heating ring 103 on the pipe fitting A is used to quickly heat the pipe fitting A, reducing the difficulty of bending.

[0038] The bending driving component 400 includes a rotating block 405 fixedly connected to the rotating shaft 502. The rotating block 405 is coaxially arranged with the rotating shaft 502. Outside the upper end of the rotating block 405, there is an adjusting sleeve 403. At the upper end of the adjusting sleeve 403, there is a handle 401 facilitating hand operation. Outside the adjusting sleeve 403, there is a sliding notch 404. The cross-section of the sliding notch 404 is L-shaped to prevent it from falling off from the sliding notch 404. A downward pressing wheel frame 407 slides in the sliding notch 404. At the end of the downward pressing wheel frame 407, a downward pressing wheel 406 is rotatably arranged. Outside the adjusting sleeve 403, there is a locking member for locking the position of the downward pressing wheel frame 407. In this way, the sliding of the downward pressing wheel frame 407 in the sliding notch 404 can be restricted, ensuring the position of the downward pressing wheel 406. During use, by pulling the handle 401 by hand, the rotating block 405 rotates along the limiting rack 402. At this time, the downward pressing wheel 406 will match with the upper end of the pipe fitting A to complete the bending.

[0039] The locking member includes a side opening provided at the outer end of the sliding slot 404. A locking sleeve 408 is provided on the surface of the adjusting sleeve 403 where the side opening is located. A limiting rack 402 is slidably provided in the locking sleeve 408. The tooth surface of the limiting rack 402 matches the tooth surface on the side of the lower pressing wheel frame 407. The other end of the limiting rack 402 is provided with an adjusting screw hole, and a first locking bolt 409 is fitted in the adjusting screw hole. The first locking bolt 409 is rotatably connected to the locking sleeve 408. By the relative rotation of the first locking bolt 409 and the limiting rack 402, under the action of the thread, the limiting rack 402 will approach the lower pressing wheel frame 407, thereby locking the position of the lower pressing wheel frame 407.

[0040] The lower pressing limiting member includes a first pressing roller frame 501 slidably provided in the vertical hole at the upper end of the mounting seat 100, and a first pressing roller 500 rotatably provided on the first pressing roller frame 501. A third locking bolt 507 for locking the position of the first pressing roller frame 501 is screwed on the side of the mounting seat 100. Since the height of the upper end of the pipe fitting A will change after replacing the pipe fitting A, fine adjustment of the height of the first pressing roller 500 is required here.

[0041] Further, buffer layers are provided on the outer sides of the lower pressing wheel 406 and the first pressing roller 500. The outer arc diameters of the lower pressing wheel 406 and the first pressing roller 500 are both larger than the outer arc diameter of the support roller set 503, so that there is no need to replace the lower pressing wheel 406 and the first pressing roller 500.

[0042] The adjusting member includes vertical columns 601 provided at both ends of the mounting seat 100. A lifting slide seat 600 is slidably sleeved on the vertical columns 601. A rotating side hole connected to the rotating shaft 502 is provided inside the lifting slide seat 600. Locking holes are provided on the outer sides of the vertical columns 601. A fourth locking bolt 602 corresponding to the locking holes is screwed on the outer side of the lifting slide seat 600. Adjusting scales are provided on the vertical columns 601. By sliding the lifting slide seat 600 on the vertical columns 601 and cooperating with the rotation and locking of the fourth locking bolt 602, the lifting position of the lifting slide seat 600 is finely adjusted. Since the support height of the support roller set 503 will change after replacing different support roller sets 503, fine adjustment is required here.

[0043] Further, the end of the rotating shaft 502 and the lifting slide seat 600 are connected by a return torsion spring. In this way, when there is no external force, the handle 401 is in a vertical state, which is convenient for the staff to operate.

[0044] A rotation limiting member is provided between the support roller set 503 and the rotating shaft 502, so that the position of the support roller set 503 can be axially restricted. The rotation limiting member includes a limiting groove 506 provided on the inner wall of the central hole of the support roller set 503 and a limiting protrusion provided on the outer side of the rotating shaft 502. The limiting protrusion and the limiting groove 506 cooperate with each other, enabling the support roller set 503 and the rotating shaft 502 to slide relative to each other but not rotate relative to each other. A positioning side block 505 is provided on the outer side of the support roller set 503, and a second locking bolt 504 for locking the rotating shaft 502 is screwed on the positioning side block 505, so that the sliding of the support roller set 503 can be restricted.

[0045] The above embodiment discloses a pipe bending device convenient for feeding. Among them, the pipe fitting A to be processed is placed at the position of the loading frame 301. By pulling up the blocking partition 304, the lowermost pipe fitting A is transferred to the position of the pushing plate 200. Then, the pipe fitting A is pushed by the pushing plate 200, and the pipe fitting A is quickly heated by the induction heating ring 103. Then, the upper end position of the pipe fitting A is limited by the first pressing roller 500. Then, the lower pressing wheel 406 is pressed down, so that the end of the lower pressing wheel 406 pulls the end of the pipe fitting A to complete the bending process around the outside of the support roller set 503. Here, different support roller sets 503 can be replaced, and then the heights of the first pressing roller 500 and the lower pressing wheel 406 can be finely adjusted to realize the processing of different pipe fittings A.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
