[0026] L-shaped plate 304 is fixedly connected in the bottom surface of the round plate 1, the first rotating shaft 302 is fixedly connected with first gear 303, the outer surface of the first gear 303 is engaged with second gear 311.

[0027] The bottom surface of the second gear 311 is fixedly installed with fixed block 305, the right-angle slide rod 306 is slidably connected in the inside of fixed block 305, the bottom surface of the fixed block 305 is fixedly connected with first fixed plate 308, the right side surface of the first fixed plate 308 is fixedly installed with electric push rod 309, the right end of the electric push rod 309 is fixedly installed with second fixed plate 310, the second fixed plate 310 is fixedly connected in the bottom surface of the right-angle slide rod 306.

[0028] The adjusting mechanism 2 further comprises a first servo motor 201 fixedly installed on the inner wall of the circular plate 1, and the output end of the first servo motor 201 is fixedly installed with a first lead screw 202, which is rotationally connected with the interior of the circular plate 1, and is threadedly connected in the interior of a first sliding block 203, which is slidingly connected with the inner wall of the circular plate 1.

[0029] The adjusting mechanism 2 further comprises a second servo motor 205 fixedly installed on the inner wall of the circular plate 1, and the output end of the second servo motor 205 is fixedly installed with a second lead screw 206, which is rotationally connected with the interior of the circular plate 1, and is threadedly connected in the interior of a second sliding block 207, which is slidingly connected with the inner wall of the circular plate 1.

[0030] As shown in Figs. 1 to 3 When the device is in use, the circular plate 1 is installed on the workbench for operation, and the interior of the circular plate 1 is provided with three installation cavities, three motors are installed in the three installation cavities, and the interior of the circular plate 1 is provided with two strip-shaped sliding grooves, and two lead screws and two sliding blocks are installed in the two strip-shaped sliding grooves.

[0031] As shown in Figs. 1 to 3 In actual operation, the adjusting mechanism 2 precisely controls the sliding of the first sliding block 203 and the second sliding block 207 in the interior of the circular plate 1 through the driving of the first servo motor 201 and the second servo motor 205, so as to realize the fine adjustment of the support positions of the two ends of the bent pipe entity 4. This design enables the bent pipe entity 4 to be stably supported during the bending process, and the support spacing can be flexibly adjusted according to needs, thereby controlling the bending radius. The bending mechanism 3 is driven by the third servo motor 301 to drive the meshing transmission of the first gear 303 and the second gear 311, so that the right-angle sliding rod 306 and the inserted pipe 307 thereon perform rotary motion around the second rotating shaft 312, thereby realizing the precise bending of the bent pipe entity 4. In addition, the telescopic function of the electric push rod 309 enables the bending mechanism 3 to adapt to bent pipe entities 4 of different lengths, further enhancing the adaptability of the device.

[0032] The working principle is as follows: in use, first, the two ends of the bent pipe entity 4 are inserted into the insertion pipe 307 and the socket 208 respectively by using the telescopic movement of the electric push rod 309, and then fixed by the telescopic movement of the electric push rod 309. Subsequently, according to the required bending angle and radius, corresponding adjustment is carried out through the adjusting mechanism 2 and the bending mechanism 3. In the adjusting mechanism 2, the first servo motor 201 drives the first screw rod 202 to rotate, and since the first screw rod 202 is in threaded connection with the first sliding block 203, the first sliding block 203 will slide along the strip-shaped sliding groove in the inner wall of the circular plate 1. The rotating roller 204 on the first sliding block 203 moves accordingly, thereby adjusting the support position of one end of the bent pipe entity 4. Similarly, the second servo motor 205 drives the second screw rod 206 to rotate, thereby driving the second sliding block 207 and the socket 208 thereon to move, further adjusting the support position of the other end of the bent pipe entity 4. Through the cooperative work of the two servo motors, the support distance of the two ends of the bent pipe entity 4 can be accurately adjusted, thereby controlling the bending radius. In the bending mechanism 3, the third servo motor 301 drives the first rotating shaft 302 to rotate, thereby driving the first gear 303 to rotate. Since the first gear 303 is in meshing connection with the second gear 311, the second gear 311 will rotate accordingly. The rotation of the second gear 311 is transmitted to the right-angle sliding rod 306 through the second rotating shaft 312, so that the right-angle sliding rod 306 and the insertion pipe 307 thereon rotate around the second rotating shaft 312. In this way, one end of the bent pipe entity 4 will be bent around the second rotating shaft 312. At the same time, through the telescopic movement of the electric push rod 309, the right-angle sliding rod 306 can be pushed to slide inside the fixed block 305, thereby realizing the use of different lengths of the bent pipe entity 4, and ensuring the adaptability. In summary, through the cooperative action of the adjusting mechanism 2 and the bending mechanism 3, the bending angle and radius of the bent pipe entity 4 can be flexibly adjusted, the bending precision and efficiency are improved, and the diversified bending requirements are met.
