They are mainly used to connect track plates for transmission and serve as the track for the support rollers to move forward. They bear large alternating loads and impact loads, as well as periodic friction from direct contact with the support rollers.

[0003] The cooling step of the quenching fluid in the forging of engineering machinery track links is a crucial step in the quenching process, directly affecting the hardness and wear resistance of the track links. Through long-term use and observation, it has been found that continuously providing cooling to the track links through circulating coolant during the quenching fluid cooling process can reduce localized overheating or insufficient cooling.

[0004] Therefore, this utility model provides a cooling and circulation device for the forging quenching fluid of engineering machinery track links. Utility Model Content

The combination of both sides can cool the track links more evenly, reduce the temperature difference between different parts, reduce deformation caused by uneven thermal stress, and ensure the dimensional stability and accuracy of the track links. The installation of vertical plates, water pumps, water pipes and water outlet pipes can continuously provide cooling to the track links by circulating coolant, reducing local overheating or insufficient cooling.

At the same time, this setting can also improve the cooling efficiency of the coolant. Since the track link maintains a high temperature during the transmission process, when they enter the coolant, they can exchange heat with the coolant more quickly, achieving rapid cooling.

[0010] Preferably, a sludge collection box is slidably fitted on the inner side wall of the bottom of the fixed seat; the sludge collection box is located below multiple conveyor rollers; this step, by setting a sludge collection box below the conveyor rollers, can collect pollutants such as oil stains and metal shavings that drip from the heated track links during the transmission process, preventing them from being directly discharged into the environment and causing environmental pollution.

[0011] Preferably, a filter screen is installed in the middle of the side wall of the pumping pipe; the filter screen is located inside the pumping pipe; this step, by setting a filter screen inside the pumping pipe, can reduce the failure rate of the pumping pump due to blockage or damage by impurities, thereby improving the stability and reliability of the pumping pump.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1.

The coolant poured from the top can quickly remove the heat from the surface of the track link, complementing the track link immersed in coolant, and achieving rapid cooling. The combination of both sides can cool the track link more evenly, reduce the temperature difference between different parts, reduce deformation caused by uneven thermal stress, and ensure the dimensional stability and accuracy of the track link.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown in the figure, a cooling and circulating device for forging quenching liquid in engineering machinery track links according to an embodiment of the present invention includes a fixed base 1; a motor 11 is fixed in the middle of the side wall of the fixed base 1; a first movable shaft 12 is fixedly connected to the output end of the motor 11; a synchronous belt 13 is driven and connected to the middle of the side wall of the first movable shaft 12; a plurality of second movable shafts 14 are driven and connected to the middle of the inner side wall of the synchronous belt 13; a conveying roller 15 is fixed to the end of both the first movable shaft 12 and the second movable shaft 14; the plurality of conveying rollers 15 rotate inside the fixed base 1; the transmission... The outer cover of the conveying roller 15 is equipped with a heat preservation component; a fixing plate 16 is fixedly connected to the middle of the side wall of the fixing base 1; a feeding component is provided in the middle of the side wall of the fixing plate 16; a cooling box 17 is fixedly connected to the inner side wall of the bottom of the fixing base 1; the fixing plate 16 is located between the conveying roller 15 and the cooling box 17; a drain pipe 18 is fixed in the middle of the side wall of the cooling box 17; both the drain pipe 18 and the cooling box 17 are hollow and connected; a spray component is provided above the cooling box 17; a discharge component is provided in the middle of the side wall of the spray component; during operation, the production personnel will quench and heat the material. The track link is placed on top of the conveyor roller 15. Then, the motor 11 is started, which drives the first movable shaft 12 to rotate. When the first movable shaft 12 rotates, it drives the timing belt 13 to rotate. When the timing belt 13 rotates, it drives multiple second movable shafts 14 to rotate. At this time, the first movable shaft 12 and the second movable shaft 14 rotate synchronously. When the first movable shaft 12 and the second movable shaft 14 rotate, the conveyor roller 15 fixed to their ends will rotate together. At this time, the conveyor roller 15 will convey the track link to the fixed plate 16. When the conveyor roller 15 is on the conveyor chain link, the heat insulation component on the side wall of the conveyor roller 15 will continue to heat the chain link. When the chain link reaches the fixed plate 16, it will enter the cooling box 17 under the guidance of the feeding component and be cooled by the coolant inside the cooling box 17. The spray component above the cooling box 17 will draw the coolant inside the cooling box 17 to the top of the cooling box 17 and pour it onto the surface of the chain link from the top. After the quenching and cooling is completed, the production personnel will use the discharge component to remove the chain link from the cooling box 17.

[0025] like Figures 1 to 3As shown, the spray assembly includes upright plates 2; the upright plates 2 are a pair and symmetrically arranged on both sides of the cooling box 17; a water pump 21 is fixed in the middle of the side wall of the fixing base 1; a water pump pipe 22 is fixedly connected to the water pump 21 at the water pump end; the water pump pipe 22 is located inside the cooling box 17; a water outlet pipe 23 is fixedly connected to the water pump 21 at the water outlet end; a water storage tank 24 is assembled at the other end of the water outlet pipe 23; the water storage tank 24 is fixed on the side wall of the upright plate 2; a connecting box 25 is fixedly connected in the middle of the side wall of the water storage tank 24; there are multiple connecting boxes 25 arranged in a circular array on the side wall of the upright plate 2. The components are arranged in a regular pattern; multiple spray pipes 26 are fixedly connected to the middle of the side wall of the connecting box 25; the cooling box 17, water pump 21, water pumping pipe 22, water outlet pipe 23, water storage tank 24, connecting box 25, and spray pipes 26 are all hollow and interconnected; during operation, when the track link falls into the cooling box 17 through the feeding assembly, the production personnel start the water pump 21, which will draw the coolant inside the cooling box 17 into the water outlet pipe 23 through the water pumping pipe 22, because the water outlet pipe 23, water storage tank 24, connecting box 25, and spray pipes 26 are all connected. With pipe 26 connected, coolant enters the water storage tank 24 and flows into multiple connecting boxes 25. Subsequently, it is sprayed into the cooling box 17 from multiple spray pipes 26. At this time, the track link is not only immersed in coolant for cooling, but also cooled by coolant poured from the top. This step, by setting up the water storage tank 24, connecting boxes 25 and spray pipes 26, not only allows the track link to be immersed in coolant for cooling, but also allows it to be cooled by pouring coolant from the top. The coolant poured from the top can quickly remove the heat from the surface of the track link, complementing the track link immersed in coolant to achieve rapid cooling. The combination of both sides can cool the track link more evenly, reduce the temperature difference between different parts, reduce deformation of the track link due to uneven thermal stress, and ensure the dimensional stability and accuracy of the track link. The vertical plate 2, water pump 21, water pump pipe 22 and water outlet pipe 23 can continuously provide cooling effect to the track link by circulating coolant, reducing local overheating or insufficient cooling.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, the insulation component includes multiple fixed cylinders 3; the fixed cylinders 3 are fixed to the side wall of the fixed base 1; the fixed cylinders 3 and the conveying rollers 15 are correspondingly arranged; a movable cylinder 31 is rotatably connected to the middle of the inner side wall of the fixed cylinder 3; the movable cylinder 31 covers the outside of the conveying rollers 15; the movable cylinder 31 and the conveying rollers 15 are fixedly connected; a first connecting pipe 32 is fixed between adjacent fixed cylinders 3; a second connecting pipe 33 is fixed to the middle of the side wall of one fixed cylinder 3; the fixed cylinders 3, movable cylinders 31, first connecting pipes 32 and second connecting pipes 33 are all hollow and connected; during operation, the production personnel connect the second connecting pipe 33 to the hot water tank. Because the fixed cylinders 3, movable cylinders 31, first connecting pipes 32 and second connecting pipes 33 are connected, the hot water entering the second connecting pipe 33 will flow between the fixed cylinders 3, movable cylinders 31, first connecting pipes 32 and second connecting pipes 33. When the conveyor roller 15 rotates, it will drive the movable cylinder 31 to rotate synchronously. Because the movable cylinder 31 and the fixed cylinder 3 are rotatably connected, the movable cylinder 31 will rotate inside the fixed cylinder 3. When the track link is moved by the conveyor roller 15, the track link will be heated and kept warm by the hot water flowing inside the movable cylinder 31. This step, by setting the fixed cylinder 3, the movable cylinder 31, the first connecting pipe 32 and the second connecting pipe 33, can reduce the heat loss of the track link during the transmission process. Since the track link has a high temperature after heating, this setting can isolate the heat transfer between the external environment and the track link, and keep the temperature of the track link stable. At the same time, this setting can also improve the cooling efficiency of the coolant. Since the track link maintains a high temperature during the transmission process, when they enter the coolant, they can exchange heat with the coolant more quickly and achieve rapid cooling.

[0027] like Figures 1 to 3 As shown, the feeding assembly includes a fixing rod 4; the fixing rod 4 is fixed to the side wall of the fixing plate 16; a guide plate 41 is rotatably connected to the middle of the side wall of the fixing plate 16; the guide plate 41 and the conveying roller 15 are correspondingly arranged; a torsion spring is provided between the guide plate 41 and the fixing rod 4; during operation, when the chain link is conveyed to the fixing plate 16 on the conveying roller 15, the chain link will push open the guide plate 41 on the side wall of the fixing plate 16, so that the guide plate 41 rotates on the side wall of the fixing rod 4, and then the chain link will pass through the guide plate. 41 enters the cooling box 17. When the track link no longer presses the guide plate 41, because there is a torsion spring between the guide plate 41 and the fixing rod 4, the guide plate 41 will return to its original position, maintaining the sealed state inside the fixing seat 1. This step, by setting the fixing rod 4 and the guide plate 41, can reduce the situation where the coolant splashes out when the track link falls into the cooling box 17, and reduce the situation where the coolant splashes out and comes into contact with other parts of the device, thus accelerating the aging or damage of the device.

[0028] like Figure 1 and Figure 2As shown, the discharge assembly includes a support plate 5; the support plate 5 is fixed between a pair of upright plates 2; an electric push rod 51 is fixedly connected to the top side wall of the support plate 5; a push plate 52 is fixedly connected to the output end of the electric push rod 51; multiple connecting rods 53 are fixedly connected to the bottom side wall of the push plate 52; a filter plate 54 is fixedly connected to the bottom side wall of the multiple connecting rods 53; the filter plate 54 slides inside the cooling box 17; during operation, after the track link has finished cooling, the production personnel start the electric push rod 51, and the output end of the electric push rod 51 will drive the push plate 52 to move upward. When the push plate 52 moves, it will... As multiple connecting rods 53 move upward, the connecting rods 53 also move upward synchronously with the filter plate 54 fixed to their bottom. At this time, the filter plate 54 will perform solid-liquid separation inside the cooling box 17, filtering the track link out of the coolant. Since the quenched track link and the cooling oil are both at high temperatures, this step, by setting up the support plate 5, electric push rod 51, push plate 52, connecting rod 53 and filter plate 54, can reduce the direct contact between the staff and the high-temperature object, reduce the safety risks caused by operational errors, and reduce the risk of burns.

[0029] like Figure 1 and Figure 3 As shown, a sludge collection box 6 is slidably fitted on the inner side wall of the bottom of the fixed base 1; the sludge collection box 6 is located below multiple conveyor rollers 15; by setting the sludge collection box 6 below the conveyor rollers 15, this step can collect pollutants such as oil stains and metal shavings that drip from the heated track links during the transmission process, preventing them from being directly discharged into the environment and causing environmental pollution.

[0030] like Figure 2 As shown, a filter screen 7 is installed in the middle of the side wall of the water pump 22; the filter screen 7 is located inside the water pump 22; by setting the filter screen 7 inside the water pump 22, the failure rate of the water pump 21 due to blockage or damage by impurities can be reduced, thereby improving the stability and reliability of the water pump 21.

[0031] Working principle: Production personnel place the quenched and heated chain links on top of the conveyor roller 15, and then start the motor 11. The motor 11 drives the first movable shaft 12 to rotate, which in turn drives the synchronous belt 13 to rotate. The synchronous belt 13, in turn, drives multiple second movable shafts 14 to rotate. At this time, the first movable shaft 12 and the second movable shaft 14 rotate synchronously. When the first movable shaft 12 and the second movable shaft 14 rotate, the conveyor roller 15, which is fixed to their ends, will also rotate together. The conveyor roller 15 will then convey the chain links to the fixed plate 16. While the conveyor roller 15 is conveying the chain links, the heat insulation component on the side wall of the conveyor roller 15 will continue to heat the chain links. When the chain links reach the fixed plate 16, they will enter the cooling box 17 under the guidance of the feeding component. The coolant is cooled by the coolant inside the cooling tank 17. A spray assembly above the cooling tank 17 draws the coolant to the top of the cooling tank 17 and pours it onto the surface of the track links. After quenching and cooling, the production staff uses the discharge assembly to remove the track links from inside the cooling tank 17. As the track links fall into the cooling tank 17 through the infeed assembly, the production staff starts the water pump 21. The water pump 21 draws the coolant from inside the cooling tank 17 into the outlet pipe 23 through the pump pipe 22. Because the outlet pipe 23, water tank 24, connecting box 25, and spray pipe 26 are connected, the coolant enters the water tank 24 and flows into multiple connecting boxes 25. It is then sprayed into the cooling tank 17 from multiple spray pipes 26. At this time, the track links do not... The device is cooled not only by immersion in coolant but also by coolant poured from the top. Production personnel connect the second connecting pipe 33 to the hot water tank. Because the fixed cylinder 3, movable cylinder 31, first connecting pipe 32, and second connecting pipe 33 are connected, the hot water entering through the second connecting pipe 33 flows between the fixed cylinder 3, movable cylinder 31, first connecting pipe 32, and second connecting pipe 33. When the conveyor roller 15 rotates, it carries the movable cylinder 31 to rotate synchronously. Because the movable cylinder 31 and fixed cylinder 3 are rotatably connected, the movable cylinder 31 rotates inside the fixed cylinder 3. As the track link moves driven by the conveyor roller 15, it is heated and kept warm by the hot water flowing inside the movable cylinder 31. The track link is then conveyed to the fixed plate 16 on the conveyor roller 15. When the chain link pushes open the guide plate 41 on the side wall of the fixed plate 16, the guide plate 41 rotates on the side wall of the fixed rod 4. Then the chain link passes through the guide plate 41 and enters the cooling box 17. When the chain link no longer presses the guide plate 41, the guide plate 41 will return to its original position because there is a torsion spring between the guide plate 41 and the fixed rod 4, maintaining the sealed state inside the fixed seat 1. After the chain link has finished cooling, the production personnel start the electric push rod 51. The output end of the electric push rod 51 will drive the push plate 52 to move upward. When the push plate 52 moves, it will take multiple connecting rods 53 upward, so that the connecting rods 53 take the filter plate 54 fixed to its bottom to move upward synchronously. At this time, the filter plate 54 will perform solid-liquid separation inside the cooling box 17, filtering the chain link out of the coolant.
