Description

Technical Field

[0001] This utility model relates to the field of sprocket processing, specifically a sprocket high-frequency quenching and cooling device. Background Technology

[0002] A sprocket is a mechanical transmission component with interlocking chain teeth. It is usually made of metal and has evenly distributed toothed structures on its outer circumference that mesh with the chain links. It is mainly used to transmit motion and power in conjunction with the chain and is widely used in the transmission systems of motorcycles, bicycles, and industrial machinery. It can realize synchronous transmission between two shafts and has the characteristics of high transmission efficiency, long distance, and strong load-bearing capacity.

[0003] The sprocket machining process typically begins by cutting round steel or forgings to the design dimensions, followed by rough machining of the inner hole, outer circle, and end face to form a blank. Next, gear teeth are machined using a gear shaper or gear hobbing machine to ensure tooth profile accuracy and uniform tooth pitch. After that, heat treatment is performed to improve the hardness and wear resistance of the teeth, followed by precision machining of the inner hole and end face through processes such as precision turning and grinding to ensure assembly accuracy. Finally, burrs are removed and surface rust prevention treatment is applied to complete the sprocket machining.

[0004] High-frequency quenching and cooling devices are required when heat treating sprockets. Most existing cooling devices are single-pass cooling devices, which means that after one side of the sprocket is cooled, it needs to be flipped over and moved to the feed port for cooling again to achieve complete cooling, resulting in long time consumption. Therefore, a high-frequency quenching and cooling device for sprockets is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

A lower distribution plate is fixedly connected to the bottom of the cooling tank; the storage tank is connected to the lower distribution plate through a first pipe; multiple sets of lower spray heads are fixedly connected to the bottom of the cooling tank; the lower spray heads are inclined at the bottom of the cooling tank; coolant is sprayed simultaneously from above and below the sprocket by the upper and lower spray heads respectively, so that the sprocket can be cooled on both sides in one conveying in the cooling tank, shortening the cooling time of a single sprocket and further improving the overall cooling efficiency. The multiple sets of upper spray heads are staggered with the conveyor shaft, and together with the inclined spray of the lower spray heads, the coolant can be evenly covered on different parts of the sprocket such as the tooth surface and hub, reducing the liquid not being sprayed onto the sprocket surface due to obstruction by the conveyor shaft, and further increasing the cooling efficiency.

[0007] Preferably, the cooling tank has a trough on its side wall; a guide box is fixedly connected to the side wall of the cooling tank; a second pipe is fixedly connected to the bottom of the guide box; a filter box is fixedly connected to the top of the second pipe; multiple sets of filter plates are fixedly connected to the middle of the filter box; a second water pump is fixedly connected to the bottom of the cooling tank; the filter box and the second water pump are connected through a second pipe; the second water pump and the storage tank are connected through a second pipe; after the sprayed coolant flows out of the trough, it is filtered by the filter plates and then pumped back to the storage tank by the second water pump for reuse, forming a cycle, reducing the need for frequent replenishment of new coolant, reducing liquid consumption, and improving the liquid recycling rate.

[0008] Preferably, a fixing seat is fixedly connected to the side wall of the cooling box; a first baffle is damped and connected to the side wall of the fixing seat; the first baffle blocks the liquid sprayed inside the cooling box, which can reduce the liquid splashing to the outside of the cooling box and causing pollution to the external environment of the cooling box. The blocking of the first baffle can also increase the utilization rate of liquid recovery from the upper and lower spray heads, further increasing the cleanliness around the cooling box.

[0009] Preferably, a support rod is fixed to the inner side wall of the cooling box; a blocking rod is fixed to the bottom end of the support rod; the blocking rod can block the stacked sprockets, so that they are laid flat on the bottom of the conveyor shaft, ensuring that each sprocket can be smoothly conveyed by the conveyor shaft, reducing the weakening of the cooling effect caused by the stacking of sprockets, and further increasing the uniformity of cooling.

[0010] Preferably, multiple sets of baffle plates are fixed to the bottom end of the support rod; the baffle plates are offset from the upper spray head; a rotating shaft is rotatably connected to the top of the baffle plates; by offsetting the multiple sets of baffle plates from the upper spray head, it is ensured that the sprocket is within the coverage area of ​​the upper spray head, and in conjunction with the lower spray head, the cooling effect on the sprocket is further increased, reducing the deterioration of the cooling effect caused by the sprocket moving to the side of the cooling box.

[0011] Preferably, an inclined plate is fixed to the side wall of the cooling box; a pair of second baffles are fixed to the top of the inclined plate; the sprocket is guided to fall by the inclined plate, so that the sprocket can directly enter the next processing device, and the second baffles cooperate to block the sides, which can reduce the sprocket from slipping off the edge of the inclined plate due to inertia and ensure that the sprocket is concentrated on the surface of the inclined plate.

[0012] The advantages of this utility model are:

[0013] 1. The high-frequency quenching and cooling device for sprockets described in this utility model sprays coolant simultaneously from above and below the sprocket using upper and lower spray heads, respectively.

[0014] 2. The high-frequency quenching and cooling device for sprockets described in this utility model involves spraying coolant, which flows out of the trough, is filtered by a filter plate, and then pumped back to the storage tank by a second water pump for reuse, forming a cycle. This reduces the need for frequent replenishment of new coolant, reduces liquid consumption, and improves the liquid recycling rate. Attached Figure Description

[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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a high-frequency quenching and cooling device for sprockets includes a cooling box 1; a motor 11 is fixedly connected to the side wall of the cooling box 1; multiple sets of conveying shafts 12 are fixedly connected to the output end of the motor 11; the conveying shafts 12 are rotatably connected to the inner side wall of the cooling box 1; a storage box 13 is fixedly connected to the side wall of the cooling box 1; a first water pump 14 is fixedly connected to the side wall of the cooling box 1; a first pipe 19 is fixedly connected to the side wall of the storage box 13; the first water pump 14 is fixedly connected to the top end of the first pipe 19; and the top end of the cooling box 1 is fixedly connected to the first water pump 14. The cooling tank 1 is equipped with an upper diverter plate 15; the first water pump 14 is connected to the upper diverter plate 15 via a first pipe 19; multiple sets of upper spray heads 16 are fixed to the top of the cooling tank 1; the upper spray heads 16 are offset from the conveyor shaft 12; a lower diverter plate 17 is fixed to the bottom of the cooling tank 1; the storage tank 13 is connected to the lower diverter plate 17 via a first pipe 19; multiple sets of lower spray heads 18 are fixed to the bottom of the cooling tank 1; the lower spray heads 18 are inclined at the bottom of the cooling tank 1; during operation, the sprocket that needs to be cooled is discharged from the cooling tank 1. The liquid is placed sideways above the conveyor shaft 12. Then, the motor 11 is started, driving multiple sets of conveyor shafts 12 to rotate. The rotation of the conveyor shafts 12 drives the sprockets above them to transport the liquid. While the conveyor shafts 12 are transporting the sprockets, the first water pump 14 is started to extract the liquid from the storage tank 13, which flows into the first pipe 19. The liquid is then sprayed from multiple sets of upper spray heads 16 and lower spray heads 18. The upper spray heads 16 and lower spray heads 18 simultaneously spray both sides of the sprockets on the conveyor shafts 12 to cool them down, so that the sprockets only need to be transported once from the middle of the cooling tank 1 to complete the process. Cooling: Coolant is sprayed simultaneously from above and below the sprocket by the upper spray head 16 and the lower spray head 18, respectively, so that the sprocket can be cooled on both sides in one conveying in the cooling box 1, shortening the cooling time of a single sprocket and further improving the overall cooling efficiency. Multiple sets of upper spray heads 16 are staggered with the conveyor shaft 12, and together with the inclined spray of the lower spray head 18, the coolant can be evenly covered on different parts of the sprocket such as the tooth surface and hub, reducing the liquid not being sprayed onto the sprocket surface due to the obstruction of the conveyor shaft 12, and further increasing the cooling efficiency.

[0025] like Figures 1 to 2As shown, a trough 2 is provided on the side wall of the cooling tank 1; a guide box 21 is fixedly connected to the side wall of the cooling tank 1; a second pipe 25 is fixedly connected to the bottom end of the guide box 21; a filter box 22 is fixedly connected to the top end of the second pipe 25; multiple sets of filter plates 23 are fixedly connected to the middle of the filter box 22; a second water pump 24 is fixedly connected to the bottom end of the cooling tank 1; the filter box 22 and the second water pump 24 are connected through the second pipe 25; the second water pump 24 is connected to the storage tank 13 through the second pipe 25; during operation, the upper spray head 16 and the lower spray head 18 spray cooling liquid onto the sprocket. The liquid can flow out from the trough 2, then flow through the guide box 21 and enter the filter box 22. The filter plate 23 filters the liquid inside the filter box 22. Then, the second water pump 24 is started to extract the liquid inside the filter box 22 and transport the filtered liquid back to the storage tank 13 through the second pipe 25 to complete the circulation. After the sprayed coolant flows out from the trough 2, it is filtered by the filter plate 23 and then pumped back to the storage tank 13 by the second water pump 24 for reuse, forming a cycle. This reduces the need for frequent replenishment of new coolant, reduces liquid consumption, and improves the liquid recycling rate.

[0026] like Figure 1 and Figure 3 As shown, a fixed seat 3 is fixedly connected to the side wall of the cooling tank 1; a first baffle 31 is dampedly connected to the side wall of the fixed seat 3; during operation, when the upper spray head 16 and the lower spray head 18 spray the sprocket above the conveyor shaft 12 to cool it down, the liquid will splash when it comes into contact with the sprocket. At this time, a pulling force can be applied to the first baffle 31 to make it rotate in the middle of the fixed seat 3. The first baffle 31 can block the liquid splashing; by blocking the liquid sprayed inside the cooling tank 1 by the first baffle 31, the liquid splashing to the outside of the cooling tank 1 can be reduced, which will cause pollution to the external environment of the cooling tank 1. The blocking by the first baffle 31 can also increase the utilization rate of liquid recovery from the upper spray head 16 and the lower spray head 18, and further increase the cleanliness around the cooling tank 1.

[0027] like Figure 4 As shown, a support rod 4 is fixedly connected to the inner wall of the cooling box 1; a blocking rod 41 is fixedly connected to the bottom end of the support rod 4; during operation, if the sprockets enter the cooling box 1 too quickly, they will stack. At this time, the blocking rod 41 blocks the stacked sprockets, so that the sprockets move flat on the conveyor shaft 12; the blocking rod 41 can block the stacked sprockets, so that they are laid flat on the bottom of the conveyor shaft 12, ensuring that each sprocket can be smoothly conveyed by the conveyor shaft 12, reducing the weakening of the cooling effect caused by the stacking of sprockets, and further increasing the uniformity of cooling.

[0028] like Figure 4As shown, multiple sets of baffle plates 5 are fixed to the bottom end of the support rod 4; the baffle plates 5 are offset from the upper spray head 16; the top of the baffle plates 5 is rotatably connected to a rotating shaft 51; during operation, the baffle plates 5 can divert and guide the sprocket at the top of the conveyor shaft 12, the sprocket can first contact the rotating shaft 51, and then the rotating shaft 51 rotates, the multiple sets of baffle plates 5 divert and guide the sprocket to directly below the spray of the upper spray head 16; by the multiple sets of baffle plates 5 being offset from the upper spray head 16, it is ensured that the sprocket is within the coverage area of ​​the spray of the upper spray head 16, and in conjunction with the lower spray head 18, the cooling effect on the sprocket is further increased, reducing the deterioration of the cooling effect caused by the sprocket moving to the side of the cooling box 1.

[0029] like Figures 1 to 3 As shown, an inclined plate 6 is fixedly connected to the side wall of the cooling box 1; a pair of second baffles 61 are fixedly connected to the top of the inclined plate 6; during operation, after the sprocket has cooled down, it can fall directly onto the surface of the inclined plate 6, and the second baffles 61 can prevent the sprocket from falling from both sides of the inclined plate 6; by guiding the sprocket down through the inclined plate 6, the sprocket can directly enter the next processing device, and cooperate with the second baffles 61 to block both sides, which can reduce the sprocket from slipping off the edge of the inclined plate 6 due to inertia, and ensure that the sprocket is concentrated on the surface of the inclined plate 6.

[0030] Working principle: The sprocket to be cooled is placed from the side of the cooling tank 1 above the conveyor shaft 12. Then, the motor 11 is started to drive multiple sets of conveyor shafts 12 to rotate. The rotation of the conveyor shafts 12 drives the sprocket above to transport the sprocket. While the conveyor shafts 12 are transporting the sprocket, the first water pump 14 is started to draw out the liquid inside the storage tank 13 and let it flow into the first pipe 19. Then, it is sprayed out from multiple sets of upper spray heads 16 and lower spray heads 18. The upper spray heads 16 and lower spray heads 18 spray both sides of the sprocket on the conveyor shaft 12 to cool it down, so that the sprocket only needs to be transported once from the middle of the cooling tank 1 to complete the cooling. The cooling liquid sprayed by the upper spray heads 16 and lower spray heads 18 on the sprocket can flow out from the trough 2. Then, the liquid flows through the guide box 21 and enters the filter box 22. The filter plate 23 filters the liquid inside the filter box 22. Then, the second water pump 24 is started to cool the liquid inside the filter box 22. The liquid is extracted and filtered, and then transported back to the storage tank 13 through the second pipe 25 to complete the circulation. When the upper spray head 16 and the lower spray head 18 spray the sprocket above the conveyor shaft 12 to cool it down, the liquid will splash when it comes into contact with the sprocket. At this time, the first baffle 31 can be pulled to make it rotate in the middle of the fixed seat 3. The first baffle 31 can block the liquid splash. When the sprocket enters the cooling tank 1 too quickly, it will stack. At this time, the blocking rod 41 blocks the stacked sprocket, so that the sprocket moves flat on the conveyor shaft 12. The baffle plate 5 can divert and guide the sprocket at the top of the conveyor shaft 12. The sprocket can first contact the rotating shaft 51, and then the rotating shaft 51 rotates. Multiple sets of baffle plates 5 divert and guide the sprocket to the area directly below the spray of the upper spray head 16. After the sprocket is cooled, it can fall directly onto the surface of the inclined plate 6. The second baffle 61 can prevent the sprocket from falling from both sides of the inclined plate 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
