[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the diaphragm spring to be quenched is placed on the feeding table, and the conveying assembly is controlled to drive the feeding table and the diaphragm spring to move on the conveying frame. After the diaphragm spring is transferred to the quenching box, the heat treatment mechanism can perform heat treatment on the diaphragm spring. After the heat treatment is completed, the diaphragm spring will be transferred to the cooling assembly for cooling, and the stress relief quenching of the diaphragm spring can be completed. During the quenching process of the diaphragm spring, impurities such as oxide scale will be generated on the outside of the diaphragm spring. As the feeding table continues to move to the right to deflect it, the diaphragm spring and some impurities will leave the feeding table. When the feeding table moves to the cleaning assembly along with the conveying assembly, the water pump The work makes it draw water from the water tank, and the water flows into the hollow shaft through the connecting pipe and the rotating joint. The water in the hollow shaft is then sprayed from the water outlet to the feeding table, wetting the feeding table and washing away some of the residual impurities. At the same time, when the conveying component is working, the hollow shaft can be driven to rotate through the transmission component, and the hollow shaft drives multiple cleaning brushes to rotate and clean the feeding table. With the flushing of water flow, the impurities attached to the feeding table can be removed. As the conveying component drives the feeding table to move, the cleaning component can continuously and uninterruptedly clean the feeding table to prevent the residual oxide scale and other impurities on the feeding table from fusing with the diaphragm spring, thereby ensuring the quality of the diaphragm spring after stress relief quenching.

[0017] 2. In the present invention, the motor drives the connecting shaft to rotate clockwise, and the connecting shaft drives the driving wheel to rotate. The driving wheel drives the driven wheel and the hollow shaft to rotate through the transmission belt. Since the connecting shaft and the hollow shaft have the same rotation direction and the feeding table at the bottom of the conveying component moves to the left, the cleaning brush rotating clockwise outside the hollow shaft is in a relative state with the moving direction of the feeding table, thereby increasing the friction between the cleaning brush and the feeding table, thereby improving the cleaning effect of the feeding table. In the process of the feeding table transferring the diaphragm spring, the limit column and the material trough in the feeding table play a role in limiting the diaphragm spring to prevent the diaphragm spring from shaking and affecting the uniformity of heating. In addition, since a leakage hole is provided at the bottom of the inner wall of the feeding table, it is convenient for the quenching liquid sprayed from the cooling component and some impurities to be able to leave the feeding table, and at the same time, it can also improve the heat transfer effect of the diaphragm spring quenching process.

[0018] 3. In the present invention, by controlling the operation of the circulating pump in the cooling assembly, the liquid guide pipe on the circulating pump can extract quenching liquid from the quenching liquid tank, so that the quenching liquid can be sprayed from the nozzle to the diaphragm spring after heat treatment. As the feeding table continues to drive the diaphragm spring to move on the conveying rack, the batch of diaphragm springs can be cooled continuously to improve work efficiency. The quenching liquid will fall into the quenching liquid tank and be filtered through the filter plate, which is convenient for collecting the quenching liquid. At the same time, the fluidity of the quenching liquid is increased, and the heat dissipation speed is increased, thereby improving the cooling effect on the diaphragm spring. After the water is sprayed out from the water outlet outside the hollow shaft, it will flow back into the water tank. The filter plate in the water tank filters the water containing impurities, so that the water in the water tank can be recycled, thereby reducing the cleaning cost of the diaphragm spring.

DETAILED DESCRIPTION

[0026] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0027] like Figure 1-6 As shown, the present invention provides a technical solution: a diaphragm spring stress relief quenching device, comprising a conveying frame 1, a conveying assembly 4 is installed in the conveying frame 1, a quenching box 2 is fixedly connected to the conveying frame 1, and a heat treatment mechanism 3 is installed on the top of the quenching box 2; a fixed frame 14 is fixedly connected to one side of the top of the conveying frame 1, a drying fan 15 is installed through the fixed frame 14, and the feeding assembly 5 is located below the drying fan 15.

[0028] The conveying component 4 includes two connecting shafts 401, which are respectively installed on both sides of the conveying frame 1. Two sprockets 402 are fixed outside the connecting shafts 401, and a chain 403 is connected between the two opposite sprockets 402. The chain 403 is provided with a plurality of mounting blocks 404; one end of one of the connecting shafts 401 is fixedly connected to a motor 405, and the motor 405 is installed on the conveying frame 1. The feeding component 5 is installed on two opposite mounting blocks 404. The mounting blocks 404 and the feeding component 5 are driven to move by the chain 403, so that the feeding component 5 and the conveying component 4 are not easily deformed by high temperature, thereby improving the operating stability of the feeding component 5.

[0029] The feeding assembly 5 includes a feeding table 501, which is installed on two opposite mounting blocks 404. A material trough 502 is provided in the middle of the feeding table 501. A limiting column 503 is fixedly connected to the middle of the inner wall of the material trough 502. A plurality of leakage holes 504 are equidistantly provided at the bottom of the inner wall of the material trough 502. The limiting column 503 and the material trough 502 serve to limit the diaphragm spring to prevent the diaphragm spring from shaking and affecting the uniformity of heating.

[0030] In this example, when the conveying component 4 moves the feeding table 501 to the leftmost side of the conveying frame 1, the drying fan 15 is controlled to work, and the wind blows toward the feeding table 501. Some water stains are discharged from the material trough 502 and the leakage hole 504, thereby accelerating the drying speed of the feeding table 501 to facilitate the subsequent transfer of the diaphragm spring.

[0031] A support frame 6 is connected to one side of the quenching box 2, and the bottom of the support frame 6 is fixed to the conveying frame 1. A cooling component 7 is installed through the support frame 6. The cooling component 7 includes a circulating pump 701, and the circulating pump 701 is installed through the top of the support frame 6. A nozzle 702 is installed at the bottom end of the circulating pump 701, and the nozzle 702 is located above the feeding component 5. The extraction end of the circulating pump 701 is connected to a liquid guide tube 703, and the bottom end of the liquid guide tube 703 is connected to the quenching liquid tank 8. Through the mutual cooperation between the circulating pump 701 and the nozzle 702, the quenching liquid can be sprayed from the nozzle 702 to the diaphragm spring after the heat treatment. As the feeding table 501 continues to drive the diaphragm spring to move on the conveying frame 1, the batch of diaphragm springs can be continuously cooled down to improve the work efficiency.

[0032] The bottom end of the cooling assembly 7 is connected to a quenching tank 8, which is arranged below the conveying frame 1. A water tank 9 is provided on one side of the quenching tank 8. Filter plates 10 are respectively installed in the quenching tank 8 and the water tank 9, and discharge valves are respectively provided on the front of the quenching tank 8 and the water tank 9. The filter plate 10 can achieve the purpose of solid-liquid separation and facilitate the cleaning of impurities. The quenching liquid will fall into the quenching tank 8 and be filtered through the filter plate 10, which is convenient for collecting the quenching liquid. At the same time, the fluidity of the quenching liquid is increased, and the heat dissipation speed is increased, thereby improving the cooling effect on the diaphragm spring.

[0033] A bottom plate 17 is provided at the bottom of the quenching tank 8 and the water tank 9, and support legs 16 are fixedly connected to the four corners of the bottom plate 17, and the four support legs 16 are respectively installed at the four corners of the bottom of the conveying frame 1; the water tank 9 is located below the conveying frame 1, and a cleaning assembly 12 is installed on the top of the water tank 9.

[0034] The cleaning component 12 includes a hollow shaft 121, and bearings 122 are respectively sleeved on both sides of the outer wall of the hollow shaft 121, and the bearings 122 are installed on the top of the water tank 9. One end of the hollow shaft 121 is connected to the liquid extraction component 13. A plurality of water outlet holes 124 are opened on the outside of the hollow shaft 121, and cleaning brushes 123 are provided on the outer wall of the hollow shaft 121 corresponding to the positions of the plurality of water outlet holes 124. Because of the cleaning brushes 123 and the water outlet holes 124, the hollow shaft 121 drives the plurality of cleaning brushes 123 to rotate and clean the feeding table 501. With the flushing of the water flow, the impurities attached to the feeding table 501 can be cleaned up, thereby improving the cleaning effect.

[0035] A transmission assembly 11 is provided at one end of the cleaning assembly 12, and the transmission assembly 11 includes a driving wheel 111 and a driven wheel 112. The driving wheel 111 is fixedly connected to one end of the connecting shaft 401, and the driven wheel 112 is fixed to the end of the hollow shaft 121. The driving wheel 111 and the driven wheel 112 are outer-mounted with the same transmission belt 113. Because the transmission belt 113 is provided, the driving wheel 111 drives the driven wheel 112 and the hollow shaft 121 to rotate through the transmission belt 113. Because the connecting shaft 401 and the hollow shaft 121 have the same rotation direction, and the feeding table 501 at the bottom of the conveying assembly 4 moves to the left, the clockwise rotating cleaning brush 123 outside the hollow shaft 121 is in a relative state with the moving direction of the feeding table 501, thereby increasing the friction between the cleaning brush 123 and the feeding table 501, thereby improving the cleaning effect of the feeding table 501.

[0036] A liquid pumping assembly 13 is installed at one end of the cleaning assembly 12 away from the transmission assembly 11. The liquid pumping assembly 13 is fixed on the back of the water tank 9, and the bottom end of the liquid pumping assembly 13 is connected to the water tank 9. The liquid pumping assembly 13 includes a water pump 131. The water pump 131 is installed on the back of the water tank 9. The bottom port of the water pump 131 is connected to the water tank 9. The top opening of the water pump 131 is connected to a connecting pipe 132. A rotating joint 133 is provided at one end of the connecting pipe 132 away from the water pump 131. The rotating joint 133 is installed at the end of the hollow shaft 121. Because of the rotating joint 133, while ensuring that the rotating joint 133 is connected to the cleaning assembly 12, it will not interfere with the rotation of the cleaning assembly 12, so that water can be normally introduced into the cleaning assembly 12.

[0037] The working principle of the present invention is:

[0038] When in use, the diaphragm spring to be quenched is placed on the feeding table 501, and the conveying component 4 is controlled to work, so that the motor 405 drives the connecting shaft 401 and the sprocket 402 to rotate, and the sprocket 402 drives the chain 403 and multiple mounting blocks 404 to move, and the mounting block 404 drives the feeding table 501 and the diaphragm spring to move on the conveying frame 1. After the diaphragm spring is transferred to the quenching box 2, the heat treatment mechanism 3 can perform heat treatment on the diaphragm spring. After completing the heat treatment work, the diaphragm spring will be transferred to the cooling component 7 for cooling.

[0039] The liquid guide tube 703 on the circulation pump 701 can extract quenching liquid from the quenching tank 8, so that the quenching liquid can be sprayed from the nozzle 702 to the diaphragm spring after heat treatment. As the feeding table 501 continues to drive the diaphragm spring to move on the conveying rack 1, the batch of diaphragm springs can be continuously cooled. The quenching liquid will fall into the quenching tank 8 and be filtered through the filter plate 10, completing the stress relief quenching work of the diaphragm spring.

[0040] During the quenching process of the diaphragm spring, impurities such as oxide scale will be generated on the outside of the diaphragm spring. As the feeding platform 501 continues to move to the right and deflects, the diaphragm spring and some impurities will separate from the feeding platform 501. When the feeding platform 501 moves to the cleaning component 12 along with the conveying component 4, the water pump 131 works to pump water from the water tank 9, and the water flows into the hollow shaft 121 through the connecting pipe 132 and the rotating joint 133. The water in the hollow shaft 121 is then sprayed toward the feeding platform 501 from the water outlet 124, so as to wet the feeding platform 501 and wash away some of the remaining impurities.

[0041] When the conveying component 4 is working, the transmission component 11 can drive the hollow shaft 121 to rotate, and the hollow shaft 121 drives multiple cleaning brushes 123 to rotate and clean the feeding platform 501. With the flushing of water flow, the impurities attached to the feeding platform 501 can be cleaned. As the conveying component 4 drives the feeding platform 501 to move, the cleaning component 12 can continuously and uninterruptedly clean the feeding platform 501. Because the motor 405 drives the connecting shaft 401 to rotate clockwise, the connecting shaft 401 is connected to the feeding platform 501. The shaft 401 drives the driving wheel 111 to rotate, and the driving wheel 111 drives the driven wheel 112 and the hollow shaft 121 to rotate through the transmission belt 113. Since the connecting shaft 401 and the hollow shaft 121 have the same rotation direction, and the feeding table 501 at the bottom of the conveying component 4 moves to the left, the clockwise rotating cleaning brush 123 outside the hollow shaft 121 is in a relative state with the moving direction of the feeding table 501, thereby increasing the friction between the cleaning brush 123 and the feeding table 501 and improving the cleaning effect.

[0042] After the water is sprayed out from the water outlet 124 outside the hollow shaft 121, it will flow back into the water tank 9. The filter plate 10 in the water tank 9 will filter the water containing impurities so that the water in the water tank 9 can be recycled. When the conveying component 4 moves the feeding platform 501 to the leftmost side of the conveying frame 1, the drying fan 15 is controlled to work, and the wind blows toward the feeding platform 501, and some water stains are discharged from the material trough 502 and the leakage hole 504.
