[0024] Embodiment 1
[0025] Refer to Figures 1-4 , a water-cooled hydraulic punching and shearing machine, including the main body 1 of the hydraulic punching and shearing machine. A fuel tank 2 and a heat absorption assembly are respectively arranged inside the main body 1 of the hydraulic punching and shearing machine. A booster pump is arranged inside the fuel tank 2, and the fuel tank 2 is connected to the water cooling box 3 through a return pipe.
[0026] The heat absorption assembly includes a water cooling box 3 arranged inside the main body 1 of the hydraulic punching and shearing machine. The inner front wall and the inner rear wall of the water cooling box 3 are both rotatably connected to a connecting pipe 4 through a sealing bearing. The opposite ends of the two connecting pipes 4 are fixedly connected to a rotating shaft 5. An inclined heat absorption plate 6 is fixedly connected to the outer surface of the rotating shaft 5. One end of the heat absorption plate 6 away from the rotating shaft 5 is fixedly connected to a power plate 7. The interiors of the power plate 7, the heat absorption plate 6, and the rotating shaft 5 are all hollow. Pressurizing boxes 8 are fixedly connected to the front and back of the water cooling box 3. Pressure pistons 9 are slidably connected to the inner walls of the two pressurizing boxes 8. Through holes are opened on the upper surfaces of the two pressure pistons 9, and one-way valves with opposite flow directions are respectively arranged on the inner walls of the two through holes.
[0027] The lower surfaces of both pressure pistons 9 are rotatably connected with connecting rods 10. The bottom ends of the two connecting rods 10 are respectively rotatably connected to the ends of the two connecting pipes 4 far away from the rotating shaft 5. The upper surface of the hydraulic punching and shearing machine body 1 is fixedly connected with a cooling box 11. The liquid inlet end of the one-way liquid inlet pipe 14 and the liquid outlet end of the one-way liquid outlet pipe 15 are respectively connected to the upper surfaces of the two pressurizing boxes 8 through pipelines. By arranging the oil return pipe, the booster pump and the power plate 7, it is convenient to drive the rotating shaft 5 to rotate during the working process of the hydraulic punching and shearing machine body 1. By arranging the water cooling box 3, the connecting pipe 4, the rotating shaft 5, the heat absorption plate 6, the power plate 7, the pressurizing box 8, the pressure piston 9, the connecting rod 10, the cooling box 11, the one-way liquid inlet pipe 14 and the one-way liquid outlet pipe 15, it can ensure that the cooling water keeps circulating during the working of the hydraulic shearing machine. By arranging the rotating shaft 5, the heat absorption plate 6 and the power plate 7, it is convenient to absorb the oil temperature of the hydraulic oil and achieve the effect of water cooling and temperature reduction.
[0028] In this embodiment, when the hydraulic punching and shearing machine body 1 is working, during the process of the hydraulic oil flowing back, it flows into the water cooling box 3 through the oil return pipe, and uses the pressure of the flowing hydraulic oil to push the power plate 7, so that the power plate 7 drives the rotating shaft 5 to rotate. During the rotation of the rotating shaft 5, the two pressure pistons 9 are driven by the two connecting pipes 4 and the connecting rods 10 to reciprocate up and down in the two pressurizing boxes 8, so that the cooling water in the cooling box 11 realizes circular flow in the cooling box 11, the one-way liquid outlet pipe 15, the pressurizing box 8, the connecting pipe 4, the rotating shaft 5, the heat absorption plate 6, the power plate 7 and the one-way liquid inlet pipe 14.

[0029] Embodiment 2
[0030] Refer to Figure 5 The inner walls of the cooling box 11 are respectively fixedly connected with a partition plate 12 and a plurality of heat absorption baffles 13. The side surface of the partition plate 12 is provided with a water passing hole, and a one-way valve flap 16 for controlling the one-way flow of the cooling water is arranged on the inner wall of the water passing hole. The upper surface and the lower surface of the cooling box 11 are both fixedly connected with heat dissipation fins 19. By arranging the heat absorption baffles 13 and the heat dissipation fins 19, it is convenient to quickly absorb and dissipate the heat in the cooling water.

Both the temperature sensor 17 and the semiconductor refrigerating sheet 18 are electrically connected to the control system inside the hydraulic punching and shearing machine body 1. By setting the temperature sensor 17 and the semiconductor refrigerating sheet 18, it is convenient to quickly refrigerate and cool the cooling water when the temperature of the cooling water is too high, ensuring the normal heat dissipation of the hydraulic punching and shearing machine body 1.
[0032] In this embodiment, when the cooling water after absorbing heat enters the cooling box 11, the heat absorption baffle 13 and the heat dissipation fins 19 are used to quickly dissipate the temperature of the cooling water. And when the water temperature is too high, the temperature sensor 17 and the semiconductor refrigerating sheet 18 are used to quickly refrigerate and cool the cooling water, ensuring the normal heat dissipation of the hydraulic punching and shearing machine body 1.
[0033] Working principle: When the water-cooled hydraulic punching and shearing machine needs to be used, during the punching process of the hydraulic punching and shearing machine body 1, the hydraulic oil enters the water-cooling box 3 through the return pipe, and the power plate 7 is pushed by the pressure of the hydraulic oil, so that the power plate 7 drives the rotating shaft 5 to rotate. During the rotation of the rotating shaft 5, the water-cooling box 3, the connecting pipe 4, the rotating shaft 5, the heat absorption plate 6, the power plate 7, the pressurizing box 8, the pressure piston 9, the connecting rod 10, the cooling box 11, the one-way liquid inlet pipe 14 and the one-way liquid outlet pipe 15 are used to keep the cooling water circulating during the operation of the hydraulic shearing machine. And during the process of the power plate 7 driving the rotating shaft 5 and the heat absorption plate 6 to rotate, the hydraulic oil can be evenly absorbed by the heat absorption plate 6 and the power plate 7, and the absorbed heat is carried to the cooling box 11 by the cooling water and dissipated by the heat absorption baffle 13 and the heat dissipation fins 19, so that the whole hydraulic punching and shearing machine has the effect of efficient water-cooled heat dissipation.
