[0002] Across numerous industries, including machinery manufacturing, automotive, and aerospace, tempered steel rods (QSRs) have become indispensable key component materials due to their excellent overall performance. Their performance directly impacts the overall quality and service life of the product. The quenching process, a key step in improving the performance of QSRs, effectively transforms the rod's internal structure by precisely controlling temperature and cooling rate, significantly enhancing key performance indicators such as hardness, strength, and wear resistance.

[0003] Conventional quenching devices for quenched and tempered rods typically use large amounts of fresh water during the quenching process. The quenched water is then directly discharged without effective water recycling. In large-scale production, this approach consumes enormous amounts of water, significantly increasing production costs. Furthermore, with increasing water scarcity and heightened environmental protection requirements, this water-intensive quenching method urgently needs improvement. To address this technical issue, the present application proposes a quenching device for quenched and tempered rods. Utility Model Content

Thereafter, the cooled water flow is pumped through pipe one and connecting pipe one to flow into pipe two. The clamping plate is rotated to cancel the clamping block, and then the handle is pulled to drive the fixed block to pull the filter plate out of the quenching box.

[0008] Furthermore, the clamping assembly includes a fixed plate located at the rear end of the quenching box, the rear end of the fixed plate is rotatably connected to a clamping plate, the top side of the front end of the clamping plate is provided with a clamping block, and the clamping block is fixedly connected to the rear end of the fixed block.

[0009] Furthermore, a tenon is fixedly connected to the front end of the fixing block, and the tenon is slidably connected to the rear end of the filter plate.

[0010] Furthermore, the middle of the front end of the second pipe is fixedly connected to the connecting pipe 1, the bottom side of the rear end of the connecting pipe 1 is fixedly connected to the pipe 1, and the pipe 1 is fixedly connected to the front end of the water tank.

[0011] Furthermore, a handle is fixedly connected to the rear end of the fixing block.

[0012] Furthermore, a support rod is fixedly connected to the right side of the bottom end of the quenching box.

[0013] Furthermore, valves are provided on the outer walls of the water outlet pipe, pipe 1 and water inlet pipe.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the quenched water will flow through the filter plate to the guide plate, and then the water on the guide plate will be cooled by the water cooling pipe, and then it will flow into the water storage tank through the gap, and then the cooled water will flow through the pipe 1 and the connecting pipe 1 to the pipe 2 by the water pump, and then flow to the nozzle through the connecting pipe 2 to quench the tempering rod again, thereby realizing water circulation, helping to reduce dependence on fresh water resources and thus reducing production costs.

A water outlet 15 for injecting coolant is provided on the left side of the rear end of the water-cooling pipe 13, and a water inlet 14 for outflowing coolant is provided on the right side of the rear end of the water-cooling pipe 13. A feeding port 3 for feeding is provided at the left end of the quenching box 1, and a discharge port 2 for discharging is provided at the right end of the quenching box 1. A connecting pipe 7 is fixedly connected to the middle part of the front end of the pipe 2 8, and a pipe 6 is fixedly connected to the bottom side of the rear end of the connecting pipe 7. The pipe 6 is fixedly connected to the front end of the water storage tank 4;

[0025] Specifically, the water source is connected to the water inlet pipe 9, and then the nozzle 11 is started to quench the tempered rod. The quenched water will flow through the filter plate 16 to the guide plate 12, and then the water on the guide plate 12 will be cooled by the water cooling pipe 13, and then flow into the water storage tank 4 through the gap. The cooled water is then pumped through pipe 1 6 and connecting pipe 1 7 to pipe 2 8, and then flows to the nozzle 11 through connecting pipe 2 10 to quench the tempered rod again, thereby realizing water circulation, which helps to reduce dependence on fresh water resources and thus reduce production costs. The coolant in the water cooling pipe 13 can be replaced through the water inlet 14 and the water outlet 15.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 , wherein the connecting pipe 2 10 located at the bottom end of the pipe 2 8 is fixedly connected to the inner wall of the quenching box 1, and the inner periphery of the connecting pipe 2 10 is fixedly connected to the nozzle 11, wherein the fixed plate 21 located at the rear end of the quenching box 1, the rear end of the fixed plate 21 is rotatably connected to the clamping plate 20, and the top side of the front end of the clamping plate 20 is provided with a clamping block 19, which is fixedly connected to the rear end of the fixed block 18, and the front end of the fixed block 18 is fixedly connected to the tenon 17, and the tenon 17 is slidably connected to the rear end of the filter plate 16, and the rear end of the fixed block 18 is fixedly connected to the handle 22, and the right side of the bottom end of the quenching box 1 is fixedly connected to the support rod 23, and the outer walls of the outlet pipe 5, pipe 1 6 and water inlet pipe 9 are all provided with valves;

[0027] Specifically, during the quenching process, the oxide scale on the surface of the tempering rod will fall off and flow with the cooling water. The filter plate 16 can intercept these oxide scales and other impurities. As the use time increases, the oxide scales and impurities on the filter plate 16 will gradually accumulate. Turn the clamping plate 20 to cancel the clamping block 19, and then pull the handle 22 to drive the fixed block 18 to pull the filter plate 16 out of the quenching box 1, clean the filter residue on the filter plate 16 or remove the filter plate 16 from the tenon 17 through the tenon 17, maintain and replace the filter plate 16, and thus maintain the filtration efficiency. The balance of the quenching box 1 can be maintained by the support rod 23, and the flow status of each pipeline can be started and stopped by the valve. The filter plate 16 can be more conveniently pulled out of the quenching box 1 through the handle 22.

[0028] Working principle: Connect the water source to the water inlet pipe 9, then open the valve, and let the water flow to the nozzle 11 through the connecting pipe 10. When the tempered rod enters the quenching box 1 from the feed port 3, start the nozzle 11 to quench the tempered rod. After that, the quenched tempered rod comes out from the discharge port 2 and can be processed in the next step. The water after quenching the tempered rod will be filtered by the filter plate 16 due to gravity and fall onto the guide plate 12. Then, the guide plate 12 is cooled by the water cooling pipe 13, and the water flow on the guide plate 12 is cooled. After that, the water flow will fall into the water storage tank 4 through the gap, and then the water pump is started to cool the water. The cooled water flows through pipe 1 6 and connecting pipe 1 7 to pipe 2 8, and then is transferred from pipe 2 8 to nozzle 11 through connecting pipe 2 10 to continue quenching the tempering rod. As the use time of the filter plate 16 increases, the clamping plate 20 is rotated to cancel the clamping block 19, and then the handle 22 is pulled to pull the filter plate 16 out through the fixed block 18 to clean the impurities on the filter plate 16, or the filter plate 16 is removed from the fixed block 18 through the tenon 17 to replace the filter plate 16, and then the filter plate 16 is installed in the quenching box 1 by holding the handle 22, and then the clamping plate 20 is rotated to clamp the clamping block 19.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
