Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, specifically to an automated quenching device with uniform water cooling. Background Technology

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Quenching refers to a metal heat treatment process in which a metal workpiece is heated to a certain appropriate temperature and held for a period of time, and then rapidly cooled by immersion in a quenching medium. Quenching equipment is required in the production and processing of aluminum profiles. A search revealed that a typical quenching equipment in the prior art is an aluminum profile quenching machine published in CN218811910U, which is related to the field of aluminum profile processing equipment. It includes a conveyor table with conveyor rollers, a support frame fixedly installed on the top side of the conveyor table, a quenching structure and an exhaust structure fixedly installed on the top side of the support frame, a liquid collection tank fixedly installed on the quenching structure, and a filter structure fixedly installed on the inner wall of the liquid collection tank. This invention, through the design of a quenching liquid tank and a collection bin, allows extruded aluminum profiles to be directly conveyed to a conveyor platform and then further conveyed by conveyor rollers. Simultaneously, a water pump is activated to extract the quenching liquid from the tank and spray it onto the aluminum profiles, achieving quenching. The used quenching liquid flows into the collection bin. Its main feature is that the reflux pump can pump the used quenching liquid back into the tank for reuse, enabling automatic quenching without manual operation, reducing waste, and saving costs.

[0003] In summary, existing quenching equipment mainly achieves cooling by spraying cooling media onto the workpiece. However, during the spray quenching process, the workpiece is prone to uneven cooling due to some parts being far from the spray point, which affects the quenching quality. To address these issues, existing equipment needs to be improved. Summary of the Invention

However, during the spray quenching process, the workpiece is prone to uneven cooling due to some parts being far away from the spray point, which in turn affects the quenching quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated quenching device with uniform water cooling, comprising a quenching chamber and a waste liquid tank.

The rotating rod is connected to the blades. One end of the diverter pipe is connected to the side wall of the waste liquid tank, and the other end of the diverter pipe is connected to the side wall of the quenching box through a drain pipe. The connection position of the drain pipe to the quenching box is higher than the position of the support plate inside the quenching box.

[0008] Preferably, the top of the quenching box is provided with a discharge port, and the discharge port is located inside the hydraulic cylinder.

[0009] Preferably, the electric valves are arranged in a ring array on the partition plate, and the electric valves are located on the outside of the heat conduction frame.

[0010] Preferably, the bearing ring is engaged with the bearing plate, and the bearing plate is correspondingly arranged with the discharge port.

[0011] Preferably, the flow interception mechanism includes a float plate, a guide block, a through hole, a first retaining seat, a sealing ring, a second retaining seat, a water inlet pipe, and a magnet. The top of the float plate is fixedly connected to the first retaining seat, and the top of the first retaining seat is provided with a second retaining seat. The second retaining seat is connected to one end of the water inlet pipe, and the other end of the water inlet pipe is connected to an external water supply device.

[0012] Preferably, the float plate is symmetrically provided with guide blocks on its side, and the guide blocks are slidably connected inside the limiting groove, while the limiting groove is symmetrically opened on the inner side wall of the water storage tank.

[0013] Preferably, the float plate has through holes arranged in a ring array, and the through holes are located on the outside of the first card holder.

[0014] Preferably, a sealing ring is provided on the inner side of the first card holder, and magnets are provided on the first card holder and the second card holder respectively, and the magnets are magnetically connected to each other.

[0015] Preferably, the blades are arranged in a ring array on the rotating rod, and one side wall of the blades is connected to the moving plate by a telescopic spring. The moving plate is slidably connected to the inner side of the guide plate, and the guide plate is symmetrically arranged on the blades. At the same time, the blades and the diverter are arranged opposite to each other.

[0016] Preferably, the heat-conducting plate is disposed on the inner wall of the waste liquid tank, and heat dissipation fins are evenly distributed on the heat-conducting plate. At the same time, the heat dissipation fins are disposed on the outside of the waste liquid tank. The waste liquid tank is provided with an external drain port and an exhaust hole, and a timer is installed on the outer wall of the waste liquid tank. The position of the external drain port on the waste liquid tank is lower than the position of the exhaust hole on the waste liquid tank.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the automated quenching device with uniform water cooling,

[0018] (1) The present invention can effectively solve the problem that existing quenching devices mainly achieve cooling by spraying cooling medium onto the workpiece. However, during the spray quenching process, the workpiece is prone to uneven cooling due to some parts being far from the spray point, which affects the quenching quality. The hydraulic cylinder pushes the partition plate down until it contacts the bottom of the quenching box. At the same time, the water stored inside the quenching box will be discharged to the top of the partition plate through the electric valve during the downward movement and contact the workpiece on the support plate, thus achieving the quenching of the workpiece. Simultaneously, the immersion quenching ensures that the workpiece and the coolant are in full contact, thereby ensuring the uniformity of quenching and the quenching quality of the workpiece. After the quenching is completed, the hydraulic cylinder pulls the support plate and the workpiece above it, as well as the cooled liquid after heat exchange, upward, which facilitates the quick removal of the quenched workpiece. At the same time, the coolant will be quickly discharged to the outside through multiple sets of drain pipes during the upward movement, thus achieving the purpose of rapid water exchange and further ensuring the quenching quality of the device, while improving the automation level of the device.

[0019] (2) This invention effectively solves the problems of low automation and inconvenience in operation of existing quenching devices by using a combination of a flow-stopping mechanism and a one-way valve to control the water injection volume manually. When the hydraulic cylinder pulls the bearing plate to move up and reset away from the one-way valve for automatic material discharge and drainage, the coolant inside the water storage tank will be automatically discharged into the quenching box through the one-way valve due to the height difference and pressure. This provides sufficient coolant for the next quenching in the quenching box. At the same time, when the coolant inside the water storage tank is discharged into the quenching box, the liquid level inside the water storage tank will decrease. When the liquid level drops, the float will move the first card seat away from the second card seat under the guidance of the guide block. After the second card seat is no longer blocked by the first card seat, the water inside the inlet pipe will be discharged into the water storage tank under the drive of the external water supply equipment, thereby realizing automatic water filling and further improving the automation level of the device. Similarly, when the water level in the water storage tank rises, the float will push the first card seat to move upward synchronously. When the first card seat is magnetically connected to the second card seat through a magnet, the inlet pipe will stop filling water into the water storage tank due to obstruction, thereby realizing continuous quantitative water filling of the device.

[0020] (3) The present invention can effectively solve the problem that existing quenching devices will generate a large amount of wastewater with residual heat after quenching the workpiece, which will easily pollute the working environment. At the same time, the energy consumption of external refrigeration devices for cooling is high. When the coolant absorbs heat in the quenching box moves up on the support plate, it will be discharged into the interior of the distribution pipe through the drain pipe and discharged to the blade through the other end of the distribution pipe, which will drive the moving plate to rotate along the rotating rod. During the rotation of the blade, the coolant will surge and expand its contact area with the airflow to achieve rapid heat dissipation. On the other hand, when the surging coolant collides with the moving plate, the moving plate will compress the telescopic spring and move inward along the guide plate. After the collision, the moving plate will move outward along the guide plate under the extension of the telescopic spring to promote the flow and surge of the coolant, and further promote the contact between the coolant and the airflow, thereby achieving the cooling of the coolant and preventing it from polluting the working environment. At the same time, it is easy to recycle it. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-6 This invention provides a technical solution: an automated quenching device with uniform water cooling, Example 1.

[0030] like Figure 1 and Figure 2 As shown, the quenching box 1 is equipped with a partition plate 2 inside, and an electric valve 3 is installed on the partition plate 2. The top of the partition plate 2 is connected to the bearing ring 5 through a heat conduction frame 4, and a bearing plate 6 is installed on the top of the bearing ring 5. The partition plate 2 is connected to the inner top of the quenching box 1 through a hydraulic cylinder 17, and a thermometer 19 is installed on the outer wall of the quenching box 1. The operator can check the heat exchange of the water coolant inside the quenching box 1 through the thermometer 19. When the temperature of the water coolant inside the quenching box 1 is too high, the operator can control the device to change the water without waiting for the set time, thereby ensuring the quenching quality and structural flexibility of the device. A water storage tank 7 is provided on one side of the quenching box 1, and a flow interception mechanism 9 is provided inside the water storage tank 7. At the same time, the water storage tank 7 is connected to the quenching box 1 through a one-way valve 8.

[0031] In a further embodiment, the top of the quenching box 1 is provided with a discharge port 18, and the discharge port 18 is located inside the hydraulic cylinder 17.

[0032] In a further embodiment, the electric valves 3 are arranged in a ring array on the partition plate 2, and the electric valves 3 are located on the outside of the heat conduction frame 4.

[0033] In a further embodiment, the bearing ring 5 is engaged with the bearing plate 6, and the bearing plate 6 is correspondingly arranged with the discharge port 18.

[0034] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the waste liquid tank 11 is located at the bottom of the quenching box 1 and is connected to the heat dissipation mechanism 13. The heat dissipation mechanism 13 includes a rotating rod 1301, a blade 1302, a diversion pipe 1303, a heat sink 1304, a heat conduction plate 1305, a telescopic spring 1306, a moving plate 1307, and a guide plate 1308. The blade 1302 is connected to the rotating rod 1301. One end of the diversion pipe 1303 is connected to the side wall of the waste liquid tank 11, and the other end of the diversion pipe 1303 is connected to the side wall of the quenching box 1 through the drain pipe 16. The connection position of the drain pipe 16 to the quenching box 1 is higher than the position of the bearing plate 6 inside the quenching box 1.

[0035] In a further embodiment, the blades 1302 are arranged in a ring array on the rotating rod 1301, and one side wall of the blades 1302 is connected to the moving plate 1307 by a telescopic spring 1306. The moving plate 1307 is slidably connected to the inner side of the guide plate 1308, and the guide plate 1308 is symmetrically arranged on the blades 1302. At the same time, the blades 1302 and the diverter pipe 1303 are arranged opposite to each other.

[0036] In a further embodiment, a heat-conducting plate 1305 is disposed on the inner side wall of the waste liquid tank 11, and heat sinks 1304 are evenly distributed on the heat-conducting plate 1305. Meanwhile, the heat sinks 1304 are disposed on the outside of the waste liquid tank 11. The waste liquid tank 11 is provided with an external drain port 15 and an exhaust hole 12. A timer 14 is installed on the outer wall of the waste liquid tank 11. The position of the external drain port 15 on the waste liquid tank 11 is lower than the position of the exhaust hole 12 on the waste liquid tank 11.

[0037] Specifically, in the actual working process, the workpiece is first placed on the support plate 6, and then the power supply is connected to set the duration of the timer 14. The hydraulic cylinder 17 pushes the partition plate 2 down until it contacts the bottom of the quenching box 1. At the same time, the coolant stored inside the quenching box 1 will be discharged to the top of the partition plate 2 through the electric valve 3 during the downward movement to contact the workpiece on the support plate 6 to achieve quenching. At the same time, since the partition plate 2 blocks the drain port of the one-way valve 8, the coolant in the water tank 7 cannot enter the interior of the quenching box 1. When the workpiece has finished cooling down, that is, after the quenching set time, the electric valve 3 is closed. Then, the hydraulic cylinder 17 pulls the support plate 6 and the workpiece above it, as well as the coolant after heat exchange, upward until the quenched workpiece is extended to the outside through the discharge port 18. Then, the workpiece can be removed and replaced with the next workpiece to be quenched. During the upward movement, the coolant will be discharged into the interior of the diversion pipe 1303 through multiple sets of drain pipes 16.

[0038] The coolant drained into the split pipe 1303 will be discharged through the split pipe 1303 to the blade 1302 inside the waste liquid tank 11, which will drive the moving plate 1307 to rotate along the rotating rod 1301. During the rotation, the blade 1302 promotes the flow and turbulence of the coolant, thereby increasing the contact area between the coolant and the airflow and achieving rapid heat dissipation. When the turbulent coolant collides with the moving plate 1307, the moving plate 1307 will compress the telescopic spring 1306 and move inward along the guide plate 1308. After the collision, the moving plate 1307 will move outward along the guide plate 1308 under the extension of the telescopic spring 1306 to promote the flow and turbulence of the coolant. The exhaust port 12 facilitates the air circulation inside and outside the device to help the coolant dissipate heat. At the same time, the heat sink 1304, with its large heat dissipation area, quickly dissipates the heat conducted by the coolant to the heat conduction plate 1305 to the outside, thus helping it to dissipate heat quickly. Meanwhile, the coolant inside the waste liquid tank 11 will be discharged to the outside through the external drain port 15.

[0039] On the other hand, when the support plate 6 moves upward, the drain port of the one-way valve 8, which was blocked by it, will be exposed. Then, the coolant in the water tank 7 will be discharged into the quenching box 1 through the one-way valve 8 to prepare for the quenching of the next workpiece. At the same time, when the coolant in the water tank 7 is discharged into the quenching box 1, the liquid level in the water tank 7 will decrease, thereby causing the interception mechanism 9 to open and close accordingly to control the liquid level height in the water tank 7.

[0040] Example 2

[0041] This embodiment is a further description of the above embodiments. It should be understood that this embodiment includes all the aforementioned technical features and is further described in detail.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a further embodiment, the flow interception mechanism 9 includes a float 901, a guide block 902, a through hole 903, a first card seat 904, a sealing ring 905, a second card seat 906, a water inlet pipe 907, and a magnet 908. The top of the float 901 is fixedly connected to the first card seat 904, and the top of the first card seat 904 is provided with the second card seat 906. The second card seat 906 is connected to one end of the water inlet pipe 907, and the other end of the water inlet pipe 907 is connected to an external water supply device.

[0043] In a further embodiment, guide blocks 902 are symmetrically arranged on the side of the float 901, and the guide blocks 902 are slidably connected inside the limiting groove 10. Meanwhile, the limiting groove 10 is symmetrically opened on the inner side wall of the water storage tank 7.

[0044] In a further embodiment, the float plate 901 has through holes 903 arranged in a ring array, and the through holes 903 are located on the outside of the first card holder 904.

[0045] In a further embodiment, a sealing ring 905 is provided on the inner side of the first card holder 904, and magnets 908 are correspondingly provided on the first card holder 904 and the second card holder 906, and the magnets 908 are magnetically connected to each other.

[0046] Specifically, after the liquid level drops, the float 901 will move the first card seat 904 away from the second card seat 906 under the guidance of the guide block 902 and the limiting groove 10. After the second card seat 906 is no longer blocked by the first card seat 904, the water inside the water inlet pipe 907 at its top will be discharged into the water storage tank 7 under the drive of the external water supply equipment. Similarly, when the water level in the water storage tank 7 rises, the float 901 will move the guide block 902 upward along the limiting groove 10, pushing the first card seat 904 upward synchronously. When the first card seat 904 is magnetically connected to the second card seat 906 through the magnet 908, the water inlet pipe 907 will stop injecting water into the water storage tank 7 due to obstruction, thereby realizing the continuous quantitative water injection of the device.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
