[0022] Embodiment 2, as Figure 1-4As shown, the bending structure 4 includes fixed blocks 401 arranged on both sides of the top of the main board 1, and the first telescopic rods 402 are installed at opposite ends of the two fixed blocks 401. The two clamps 2 are respectively installed at the output ends of the two first telescopic rods 402, one end of one of the fixed blocks 401 is located on one side of the two clamps 2 and is installed with a second telescopic rod 403, and the output end of the second telescopic rod 403 is fixed with a bending block 404, and the inner walls on both sides of the frame 3 are installed with third telescopic rods 5, and the output ends of the two third telescopic rods 5 are respectively fixed to the two fixed blocks 401, and the cleaning structure 6 includes a first water outlet 601 installed on the top of the frame 3, and a connecting pipe 602 is fixed to the bottom end of the first water outlet 601, and the bottom end of the connecting pipe 602 passes through the bottom end of the frame 3 and is fixed with a water outlet pipe 603, and a plurality of first nozzles 604 are installed on the outer wall of the bottom end of the water outlet pipe 603, and the first nozzles 604 are arranged at Above the two splints 2, the water-expanding structure 11 includes two fourth telescopic rods 1101 installed on the inner wall of the inner cavity 7, and the output ends of the two fourth telescopic rods 1101 are respectively installed with second nozzles 1102 matching the openings on both sides of the lower mold 8, and the bottom ends of the two second nozzles 1102 are fixed with circulation pipes 1103.

[0023] The effect achieved by the entire embodiment 2 is that the operation of the two first telescopic rods 402 can drive the two clamping plates 2 to move, clamp and fix the steel pipe, and then the operation of the second telescopic rod 403 drives the bending block 404 to move, thereby bending the steel pipe. At the same time, the first water outlet 601 operates to allow water to pass through the connecting pipe 602 and the water outlet pipe 603 and be sprayed from the first nozzle 604, achieving the effect of spraying and washing the steel pipe, and achieving the effect of integrated bending and washing. After the steel pipe is bent, the synchronous operation of the two third telescopic rods 5 will drive the two fixing blocks 401 to move, thereby driving the bending held by the two clamping plates 2. The tube moves, and when it moves to the appropriate position, the two clamps 2 are loosened, allowing the bent tube to fall into the processing tank of the lower mold 8. At this time, the clamps 2 are reset, and the cylinder 9 drives the upper mold 10 to move down and fit with the lower mold 8.

Through the operation of the second water outlet 1104, water is sprayed from one of the second nozzles 1102, and water is sprayed and pressurized into the steel tube, so that the steel tube forms the shape of the groove in the mold, achieving the effect of water swelling. After the water swelling is completed, water flows into the second water outlet 1104 from the other second nozzle 1102 again.

[0024] In other preferred embodiments, the cleaning mechanism 6 can adopt ultrasonic cleaning technology. For example, an ultrasonic generator and an ultrasonic transducer are arranged inside the cleaning mechanism 6, so that when the ultrasonic generator and the ultrasonic transducer are started, the liquid inside the cleaning mechanism can produce small molecule high-frequency oscillations, and then spray the steel pipe through the existing ultrasonic atomizing nozzle to improve the cleaning effect of the cleaning mechanism 6.

[0025] Working principle: When the device is used, the user puts the steel pipe to be processed between the two clamping plates 2. The operation of the two first telescopic rods 402 can drive the two clamping plates 2 to move and clamp the steel pipe. Then, the operation of the second telescopic rod 403 drives the bending block 404 to move, thereby bending the steel pipe. At the same time, the first water outlet 601 operates to allow water to pass through the connecting pipe 602 and the water outlet pipe 603 and be sprayed from the first nozzle 604, thereby achieving the effect of spraying and washing the steel pipe and achieving the integrated effect of bending and washing. After the steel pipe is bent, the synchronous operation of the two third telescopic rods 5 will drive the two fixed blocks 401 to move, thereby The bent pipe clamped by the two clamps 2 is moved. When it moves to the appropriate position, the two clamps 2 are loosened, allowing the bent pipe to fall into the processing tank of the lower mold 8. At this time, the clamps 2 are reset, and the cylinder 9 drives the upper mold 10 to move down and fit with the lower mold 8. The two fourth telescopic rods 1101 operate synchronously, driving the two second nozzles 1102 to align and fit the two ends of the steel pipe. Through the operation of the second water outlet 1104, water is sprayed from one of the second nozzles 1102 to spray water and pressurize the steel pipe, so that the steel pipe forms the shape of the groove in the mold to achieve the effect of water swelling. After the water swelling is completed, water flows into the second water outlet 1104 from the other second nozzle 1102 again.

[0026] The wiring diagram of the first telescopic rod 402, the second telescopic rod 403, the third telescopic rod 5, the first water outlet 601, the cylinder 9, the fourth telescopic rod 1101 and the second water outlet 1104 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the first telescopic rod 402, the second telescopic rod 403, the third telescopic rod 5, the first water outlet 601, the cylinder 9, the fourth telescopic rod 1101 and the second water outlet 1104 are no longer explained in detail.
