Description

Technical Field

[0001] The utility model belongs to the technical field of output shaft processing, and particularly relates to a rapid cooling device for processing a reducer output shaft. Background Technique

[0002] The output shaft of a speed reducer refers to the final output component inside the speed reducer after deceleration through mechanisms such as gear transmission. It bears the transmitted force and torque and outputs them to external equipment or mechanical systems. When producing the output shaft of a speed reducer, under the action of high temperature and pressure, the metal undergoes plastic deformation in the solid state, thereby changing its organizational structure and shape. After hot forging, rapid cooling is required to improve the mechanical properties and wear resistance of the output shaft of the speed reducer.

[0003] In the prior art, there is a rapid cooling device for processing a reducer output shaft with a patent publication number of CN216337864U. The above patent includes a bottom plate. A cooling box is fixedly connected to the top of the bottom plate. Card slots are fixedly connected to the outer surfaces on both sides of the cooling box. A clamping plate is movably clamped inside the card slots. Cooling components are arranged on both sides of the cooling box. The cooling components include an outer cooling plate fixedly connected to one end of the clamping plate. An inner cooling plate is fixedly connected to one side of the outer cooling plate. A cooling pipe is embedded inside the inner cooling plate. An exhaust pipe is arranged on the top of the cooling box. One end of a limiting column is movably connected to a filter screen frame. An adsorption plate is arranged inside the filter screen frame. By spraying water through a water pipe nozzle arranged at the top end inside the cooling box for cooling, circulating coolant is injected into the cooling pipes in the cooling components on both sides, which can accelerate the cooling speed of metal parts inside the cooling box. Conveying the metal parts through a mesh conveyor belt can avoid the risk of scalding during manual conveying. However, there are still the following deficiencies in actual use: Starting from reality, the device conveys high-temperature workpieces through a mesh conveyor belt, but the mesh conveyor belt is only a flat surface, and the high-temperature output shaft is prone to rolling on the top of the conveyor belt, with a risk of falling and potential safety hazards. At the same time, the device cools high-temperature workpieces by spraying water through a nozzle, but lacks a water collection device, resulting in a large amount of water resource waste.

[0004] Therefore, a rapid cooling device for processing a reducer output shaft is needed to solve the problems in the prior art, such as the lack of a limiting mechanism that makes workpieces prone to falling during conveying and the lack of a water collection device that causes water resource waste.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4 , the present utility model provides a rapid cooling device for processing the output shaft of a speed reducer, including a bottom plate 1. A box body 2 is fixedly connected to the top of the bottom plate 1. A mesh conveyor belt 3 is arranged inside the box body 2. A plurality of limit boxes 4 are fixedly connected to the top of the mesh conveyor belt 3. Support plates 5 are fixedly connected to the front and rear ends of the box body 2 near the top position. Two electric telescopic rods 6 are installed at the bottom of each of the two support plates 5. A baffle 7 is fixedly connected to the bottom of each two corresponding electric telescopic rods 6. Water circulation mechanisms 8 corresponding to the box body 2 are arranged at both sides near the top of the bottom plate 1. A first exhaust pipe 9 is fixedly connected to the top of the box body 2. A filter box 10 is fixedly connected to one side of the first exhaust pipe 9. A second exhaust pipe 11 is fixedly connected to one side of the filter box 10. A suction fan 12 is fixedly connected to one side of the second exhaust pipe 11. A third exhaust pipe 13 is fixedly connected to one side of the suction fan 12.

[0023] Furthermore, as in Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically noting that a plurality of shock pads are fixedly connected to the bottom of the bottom plate 1. The shock pads play a role in buffering and shock absorption, enabling the bottom plate 1 to always maintain a stable state during the entire cooling operation, and improving the working stability of the device.

[0024] Furthermore, as shown in Figure 1 and Figure 2 it is worth specifically noting that a plurality of uniformly distributed water permeable holes are provided on the surface of the limit box 4. Through the plurality of water permeable holes, it is ensured that the water entering the interior of the limit box 4 can flow out in time and is collected by the water circulation mechanism 8 for reuse.

[0025] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically noting that through slots are provided at both the front and rear ends of the box body 2, and the inner surface of the baffle 7 is closely attached to the through slots. The provided through slots ensure that the mesh conveyor belt 3 drives the limit box 4 to pass through smoothly. At the same time, the close attachment of the inner surface of the baffle 7 to the through slots ensures that the flue gas generated during water quenching does not escape from the connection between the baffle 7 and the through slots.

[0026] According to the above working process, it can be seen that by providing a plurality of limit boxes 4, the high-temperature output shafts of the reducer are respectively placed inside the plurality of limit boxes 4, preventing the output shafts from rolling down when moving with the mesh conveyor belt 3, thereby reducing the occurrence of accidents, improving work safety, making the position of each output shaft on the mesh conveyor belt 3 fixed, and enabling the simultaneous cooling of multiple output shafts, so that the cooling operation can be carried out more precisely and the efficiency of the cooling work is improved.

[0027] Furthermore, as shown in Figure 4 it is worth specifically noting that the water circulation mechanism 8 includes a condensation water tank 801 fixedly connected to the top of the bottom plate 1. A water filling port 802 is provided at the top of the condensation water tank 801. A first water delivery pipe 803 is fixedly connected to the inner side of the condensation water tank 801. A second water delivery pipe 804 is fixedly connected to the front end of the condensation water tank 801. A water pump 805 is fixedly connected to the front end of the second water delivery pipe 804. A third water delivery pipe 806 is fixedly connected to the top of the water pump 805. A spray head 807 is installed at the bottom of the third water delivery pipe 806. By providing the water circulation mechanism 8, recycling is achieved, greatly saving water resources and enhancing the environmental friendliness of the device.

[0028] Furthermore, as shown in Figure 4 it is worth specifically noting that the first water delivery pipe 803 penetrates through the bottom position of the box body 2 to ensure that the first water delivery pipe 803 can recycle the water after water quenching. The third water delivery pipe 806 penetrates through the top position of the box body 2 to ensure that water can pass through the third water delivery pipe 806 and be sprayed out from the spray head 807 to perform water quenching and cooling on the high-temperature output shafts of the reducer.

[0029] Furthermore, as shown in Figure 4 It is worth specifically explaining that an activated carbon adsorption plate is slidably connected to the top of the filter box 10. The activated carbon adsorption plate can adsorb the flue gas generated during water quenching, avoiding direct discharge and causing environmental pollution. At the same time, the sliding connection facilitates the staff to replace the saturated activated carbon adsorption plate.

[0030] This solution has the following working process: During actual use, the high-temperature output shaft of the reducer is placed inside the limit box 4 and moves along with the mesh conveyor belt 3. After moving into the box body 2, the electric telescopic rod 6 drives the baffle 7 to descend to seal the box body 2. Then, the water pump 805 is turned on to drive the water in the condensation water tank 801 to spray out from the nozzle 807, quenching and cooling the output shaft of the reducer inside the box body 2. The water that comes into contact with the output shaft flows into the bottom of the box body 2 and then returns to the condensation water tank 801 through the first water pipe 804 for condensation, achieving recycling. At the same time, the suction fan 12 is turned on to adsorb the flue gas generated during water quenching, and the flue gas is discharged after passing through the filter box 10.

[0031] In summary: By setting multiple limit boxes 4 and placing the high-temperature output shafts of the reducer inside the multiple limit boxes 4 respectively, it is avoided that the output shafts roll down when moving along with the mesh conveyor belt 3, thus reducing the occurrence of accidents, improving work safety, making the position of each output shaft on the mesh conveyor belt 3 fixed, and enabling the simultaneous cooling of multiple output shafts, so that the cooling operation can be carried out more precisely and the efficiency of the cooling work is improved; by setting the water circulation mechanism 8, the water pump 805 is turned on to drive the water in the condensation water tank 801 to spray out from the nozzle 807, quenching and cooling the output shaft of the reducer inside the box body 2. The water that comes into contact with the output shaft flows into the bottom of the box body 2 and then returns to the condensation water tank 801 through the first water pipe 804 for condensation, achieving recycling, greatly saving water resources and enhancing the environmental protection of the device.
