AI Technical Summary
Existing pipe bending equipment lacks a limiting structure, which makes the steel pipes prone to deviation during transportation, resulting in a high rate of defective pipe bending and affecting processing efficiency.
A conveying assembly including a support ring, a threaded rod, a connecting frame, and a limiting ring is designed. The limiting ring is made to fit with the support ring by rotating the threaded rod, thereby limiting the position of the steel pipe. The support position is adjusted by slide rails and multiple sliding plates to stabilize the steel pipe. Combined with a motor-driven guide shaft and a bending frame, the steel pipe can be stably conveyed and bent.
This effectively prevents the steel pipe from tilting during movement, reduces the defect rate of bent pipes, and improves the processing efficiency of bent pipes.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] Reference Figure 1-5 A high-efficiency pipe bending processing equipment for marine steel pipes includes a workbench 1, a conveying component 3 and a limiting component 2 fixedly connected to the top of the workbench 1, a pipe bending component 4 provided on the side of the workbench 1, and the limiting component 2 located between the conveying component 3 and the pipe bending component 4.
[0024] The limiting component 2 includes a fixing block 201. A slide rail 202 is fixedly connected to the side surface of the fixing block 201. A slide plate 203 is slidably connected to the circumferential surface of the slide rail 202. A support ring 204 is fixedly connected to the top of the slide plate 203. A connecting block 205 is fixedly connected to the front end of the support ring 204. A limiting post 210 and a threaded rod 206 threaded inside the connecting block 205 are fixedly connected to the top of the connecting block 205. A connecting frame 207 is threadedly connected to the outside of the threaded rod 206. A limiting ring 208 is fixedly connected to the end of the connecting frame 207 away from the threaded rod 206, and the limiting ring 208 corresponds to the position of the support ring 204. A limiting groove 209 is opened at the bottom of the connecting frame 207, and the limiting post 210 engages with the inside of the limiting groove 209. When conveying the steel pipe, the conveying assembly 3 can place the steel pipe inside the support ring 204 and rotate the threaded rod 206 so that the connecting frame 207 drives the limiting ring 208 to fit against the support ring 204. This limits the steel pipe without affecting its conveying, preventing it from tilting during movement, reducing the defect rate of the bent pipe, and thus improving the efficiency of the bent pipe.
[0025] A mounting block 211 is fixedly connected to the front end of the slide plate 203. A limiting screw 212 is threaded into the interior of the mounting block 211, and the bottom of the limiting screw 212 is in contact with the top of the worktable 1. The slide plate 203 can slide outside the slide rail 202, thereby adjusting the position of the top support ring 204 of the slide plate 203. This allows for support based on the changing position of the steel pipe's center of gravity, ensuring the stability of the steel pipe's movement. After adjusting the position, the limiting screw 212 can be rotated to position the slide plate 203, preventing lateral movement of the slide plate 203 and thus avoiding interference with the steel pipe's transport.
[0026] Multiple sliding plates 203 are provided and are arranged laterally on the slide rail 202. The multiple sets of sliding plates 203 can provide timely support when the center of gravity of the moving steel pipe changes.
[0027] The conveying assembly 3 includes a control console 301, inside which a first motor 302 is installed. The output end of the first motor 302 is fixedly connected to a first guide shaft 303. A second guide shaft 304 is rotatably connected to the front end face of the control console 301, and the second guide shaft 304 corresponds to the position of the first guide shaft 303. When the first motor 302 is working, it drives the first guide shaft 303 to rotate, thereby conveying the steel pipe with the cooperation of the second guide shaft 304.
[0028] The pipe bending assembly 4 includes a mounting groove 401. A second motor 402 is fixedly connected to the bottom inner part of the mounting groove 401. A rotating column 403 is fixedly connected to the output end of the second motor 402. A fixing ring 404 and a bending frame 406 are fixedly connected to the circumferential surface of the rotating column 403. A movable frame 405 is fixedly connected to the rear end face of the fixing ring 404. The end of the movable frame 405 away from the fixing ring 404 is rotatably connected to the bottom of the worktable 1. When the second motor 402 is working, it drives the bending frame 406 and the fixing ring 404 to rotate through the rotating column 403, thereby driving the movable frame 405 to rotate.
[0029] The top of the movable frame 405 has a sliding groove 408. A lead screw 409 is rotatably connected to the inner wall of the sliding groove 408. The end of the lead screw 409 extending to the outside of the movable frame 405 is fixedly connected to the output end of the servo motor 410. A clamping frame 411 is threadedly connected to the outside of the lead screw 409. A mating block 407 is fixedly connected to the outer surface of the bending frame 406, and the mating block 407 corresponds to the position of the clamping frame 411. When the steel pipe is conveyed to the position of the mating block 407, the servo motor 410 works, using the lead screw 409 to push the clamping frame 411 to cooperate with the mating block 407 to clamp the steel pipe, and the steel pipe is bent by the rotation of the movable frame 405.
[0030] Working principle: During use, the first motor 302 operates, driving the first guide shaft 303 to rotate, thereby conveying the steel pipe with the cooperation of the second guide shaft 304. During the movement, the steel pipe gradually passes through the ring formed by the limiting ring 208 and the support ring 204 until it corresponds to the position of the docking block 407. When the steel pipe is conveyed to the position of the docking block 407, the servo motor 410 operates, using the lead screw 409 to push the clamping frame 411 to cooperate with the docking block 407 to clamp the steel pipe. When the second motor 402 operates, it drives the bending frame 406 and the fixing ring 404 to rotate through the rotating column 403, thereby driving the moving frame 405 to rotate. The bending of the steel pipe is achieved by the rotation of the moving frame 405.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
