[0026] The output end of the motor 11 is drivingly connected to the lower end of the bending wheel 3 , the liquid inlet pipe 8 is communicated with the inside of the liquid storage tank 71 , and the inner wall of the tightening block 6 and the fixing groove 24 is fixedly connected with a rubber pad.

[0027] Through the fixing mechanism 2, the hydraulic cylinder 22 can drive the fixing block 23 to move toward the pulley 21, so as to clamp the pipeline, that is, fix the pipeline, thereby preventing the pipeline from popping out and scratching the pipeline, thereby not affecting the appearance and quality. Through the cooling mechanism 7, the nozzle 74 can spray out cooling liquid, thereby reducing the heat generated after the pipeline is bent, thereby reducing the pipeline bending deformation rate and increasing the pipeline bending forming rate.

[0028] like Figure 3-4 As shown, the fixing mechanism 2 includes a pulley 21, the lower end of the pulley 21 is rotatably connected to the left front side of the upper end of the processing base 1, a hydraulic cylinder 22 is installed on the rear side of the pulley 21, the output end of the hydraulic cylinder 22 is fixedly connected to a fixing block 23, a slide groove 25 is provided at the front end of the fixing block 23, a slide groove 25 is provided on the left rear side of the upper end of the processing base 1, guide grooves 26 are symmetrically provided on the left and right inner walls of the slide groove 25, a slider 27 is slidably connected inside the slide groove 25, and guide blocks 28 are fixedly connected to the left and right ends of the slider 27.

[0029] The lower end of the hydraulic cylinder 22 is fixedly connected to the left rear side of the upper end of the processing base 1 , and the fixed block 23 is aligned with the position of the pulley 21 .

[0030] The guide block 28 is slidably connected to the guide groove 26 .

[0031] When the fixed block 23 moves, it will drive the slider 27 and the guide block 28 to slide synchronously in the slide groove 25 and the guide groove 26 respectively, thereby improving the micro-movement of the fixed block 23 and improving its fixing effect. At the same time, the rubber pads arranged on the fixed block 23 and the tightening block 6 can avoid scratches on the pipeline and avoid affecting the appearance and quality of the pipeline.

[0032] like Figure 5 As shown, the cooling mechanism 7 includes a liquid storage tank 71. The liquid storage tank 71 is opened at the lower end of the inner part of the processing base 1. A water pump 72 is fixedly connected to the lower right end of the liquid storage tank 71. A delivery pipe 73 is installed at the right end of the processing base 1. A nozzle 74 is fixedly installed on the lower side of the top of the delivery pipe 73.

[0036] The working principle of the ship heat exchanger pipe bending device is described in detail below.

[0037] like Figure 1-5As shown, when the heat exchanger pipe bending device for a ship is used, first, the pipe can be placed between the pulley 21 and the fixing block 23, and the bent end of the pipe is located between the side of the wheel body of the bending wheel 3 and the tightening block 6. Then, the cylinder 5 can be started to drive the tightening block 6 to move toward the pipe, and then the pipe can be clamped by the tightening block 6. At the same time, the hydraulic cylinder 22 can be started to drive the fixing block 23 to move toward the pipe, and then the bottom of the pipe can be fixed by the fixing groove 24 and the pulley 21 to avoid bending. When the pipe is bent, the water pump 72 can be started to extract the coolant in the liquid storage tank and transport it to the nozzle 74 through the delivery pipe 73. Finally, the coolant is sprayed onto the bend of the pipe through the nozzle 74, so as to cool it down, thereby reducing the heat generated after the pipe is bent, thereby reducing the pipe bending deformation rate.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
