Description

Technical Field

[0001] This invention specifically relates to a combined air-mist-water quenching and cooling device and its control method. Background Technology

[0002] With the rapid development of the new energy industry (such as new energy vehicles and energy storage equipment), lightweight metal materials such as aluminum alloys and magnesium alloys are widely used in battery pack housings, motor housings and vehicle body structural parts due to their excellent strength and processing performance. These key components usually need to undergo solution treatment (quenching) to obtain the required strength and toughness. The cooling rate and uniformity of the quenching process directly determine the final performance and dimensional accuracy of the product. In quenching, cooling is usually achieved through a single medium.

[0003] Existing quenching cooling methods are relatively crude, making it difficult to achieve graded control and continuously control the cooling rate of metal parts at each cooling stage. Furthermore, the residual coolant on the surface after quenching can affect subsequent processes. To address this, we propose a combined air-mist-water quenching cooling device and its control method. Summary of the Invention

[0004] The purpose of this invention is to provide a combined air-mist-water quenching and cooling device and its control method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combined air-mist-water quenching and cooling device and its control method, comprising:

[0006] A cooling tank, the sidewall of which has an atomizing component communicating with its interior, through which mist is blown into the interior of the cooling tank;

[0007] A vertical plate is fixed to the upper surface of the cooling tank, and the front surface of the vertical plate has a first air nozzle that can blow out airflow in the middle, and the rear surface of the vertical plate has an air guiding structure that communicates with the first air nozzle.

[0008] The side panel is mounted to the side wall of the upright plate via a rotating assembly, and a second air nozzle is provided on the front surface of the side panel;

[0009] A gas collection trough is provided on the upper part of the front surface of the vertical plate to collect the escaping mist and airflow.

[0010] Preferably, the rotating assembly includes a rotating column, a gear, and a toothed plate. The rotating column is fixed to one end face of the side plate to rotate and engage with a connecting ring at one end of the vertical plate. The gear is fixed to the outer surface of the rotating column. The toothed plate is slidably mounted on the vertical plate through a guide groove, and the toothed plate meshes with the gear.

[0011] Preferably, the rotating assembly further includes a motor, which is fixed to the upright plate, and one end of the motor is connected to a lead screw. A ring sleeve that is threadedly engaged with the lead screw is fixed to one end of the upper surface of the toothed plate.

[0012] Preferably, the toothed plate sidewall protrudes outward to form a protrusion, and the inner wall of the guide groove is provided with a sliding groove that mates with the protrusion.

[0013] Preferably, the air guiding structure includes a first guide block, a telescopic hose, and a second guide block. The first guide block is fixed to the middle of the rear surface of the upright plate, and the second guide block is arranged side by side with the first guide block to communicate internally through the telescopic hose. One end of the second guide block is provided with an air inlet.

[0014] Preferably, the atomizing component includes a spray nozzle and an air inlet pipe. The spray nozzle is fixed to the inner wall of the cooling tank, the air inlet pipe is connected to one end of the spray nozzle for air intake, and a liquid inlet pipe is provided on the spray nozzle, with one end of the liquid inlet pipe connected to coolant.

[0015] Preferably, a second support plate is rotatably connected to the lower surface edge of the side plate, one end of the second support plate is rotatably connected to a first support plate via a rotating shaft, and one end of the first support plate is rotatably connected to a fixing plate, the fixing plate being fixedly engaged with the cooling tank.

[0016] Preferably, the side plate is symmetrically arranged in two places along the vertical plate.

[0017] Preferably, multiple first air nozzles are provided, and the first air nozzles are distributed in an array along the surface of the upright plate.

[0018] A method for regulating combined air-mist-water quenching cooling, using the aforementioned cooling device, includes the following steps:

[0019] Step A: Lift the quenched metal part and move it to the upper part of the inner side of the cooling tank, without contacting the coolant inside the cooling tank. The high-pressure airflow flows into the inside of the spray nozzle through the air inlet pipe, and at the same time, the coolant flows into the inside of the spray nozzle through the liquid inlet pipe. After atomization, it is sprayed out, and the high-speed flowing mist comes into contact with the surface of the metal part.

[0020] Step B: After the metal part is cooled by the mist, it is sent into the middle of the inner side of the cooling tank and comes into contact with the cooling liquid inside. At this time, the metal part is wrapped by the coolant and is cooled down quickly.

[0021] Step C: Raise the height of the metal part to correspond with the first air nozzle. The airflow enters the second guide block, the telescopic hose and the inside of the first guide block through the air inlet in sequence, and flows out from the first air nozzle to contact the metal part, thereby achieving final cooling through the airflow and drying the coolant on the surface of the metal part.

[0022] Step D: When the metal part is small, the motor drives the lead screw to rotate. The lead screw engages with the ring sleeve thread on the toothed plate to drive the toothed plate to move. The toothed plate drives the rotating column to rotate through the gear meshing with it, thereby causing the side plate to rotate toward the metal part. This allows the first blower nozzle on the side plate to face the metal part better and shorten the distance to the metal part, thereby improving the utilization of airflow.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention, by incorporating an atomizing component, a vertical plate, a side plate, a first air nozzle, and an air collection groove, avoids the limitations of traditional, simplistic cooling methods that hinder tiered cooling. During quenching, this device first allows the metal part to come into contact with room-temperature air and a small amount of atomized coolant for simple, relatively gentle cooling. Then, rapid cooling is achieved through contact with a large amount of coolant. Finally, airflow is used to cool and dry the surface coolant, facilitating precise control of the cooling rate at each stage after quenching. This allows for precise tiered cooling regulation, ensuring high material performance while effectively controlling post-quenching deformation, guaranteeing product quality. Furthermore, the absence of residual coolant on the metal part surface after cooling facilitates rapid subsequent processing. Attached Figure Description

[0033] 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.

[0034] Please see Figures 1-7 This invention provides a technical solution: a combined air-mist-water quenching and cooling device and its control method, comprising:

[0035] Cooling tank 1, the side wall of cooling tank 1 has an atomizing component 2 communicating with its interior, and the atomizing component 2 blows mist into the interior of cooling tank 1;

[0036] The upright plate 3 is fixed to the upper surface of the cooling tank 1, and the middle of the front surface of the upright plate 3 has a first air nozzle 5 that can blow out airflow, and the rear surface of the upright plate 3 has an air guiding structure that is connected to the first air nozzle 5.

[0037] This invention achieves a three-stage graded cooling process of "mist pre-cooling → coolant strong cooling → airflow final cooling and drying", which can precisely control the cooling rate of metal parts at each stage after quenching. While ensuring the material achieves high performance, it effectively suppresses quenching deformation and ensures product quality. Compared with the traditional single-medium quenching method, this invention has a wide range of adjustable cooling rates through the synergistic combination of wind, mist and water, which can adapt to the quenching needs of metal parts with different materials, wall thickness and cross-sectional shape.

[0038] Side plate 4 is mounted on the side wall of upright plate 3 via a rotating assembly, and a second air nozzle is provided on the front surface of side plate 4;

[0039] The air collection trough 6 is located on the upper part of the front surface of the vertical plate 3 to collect the escaping mist and airflow.

[0040] It avoids fogging in the working environment, improves operating conditions, and reduces unnecessary loss of cooling medium.

[0041] Preferably, the rotating assembly includes a rotating column 81, a gear 83, and a toothed plate 87. The rotating column 81 is fixed to one end face of the side plate 4 to rotate and engage with the connecting ring 82 at one end of the vertical plate 3. The gear 83 is fixed to the outer surface of the rotating column 81. The toothed plate 87 is slidably mounted on the vertical plate 3 through the guide groove 89, and the toothed plate 87 meshes with the gear 83.

[0042] This meshing transmission structure has the advantages of smooth transmission and precise angle positioning, which can ensure that the side plate 4 remains stable during adjustment and ensure that the air outlet direction of the first blower 5 is accurately aligned with the metal part, thereby improving cooling efficiency.

[0043] Preferably, the rotating assembly further includes a motor 85, which is fixed on the vertical plate 3, and one end of the motor 85 is connected to a lead screw 86. A ring sleeve that is threadedly engaged with the lead screw 86 is fixed to one end of the upper surface of the toothed plate 87.

[0044] The rotational motion of the lead screw 86 is converted into the linear motion of the gear plate 87, which in turn drives the side plate 4 to rotate through gear and rack meshing. This structure is easy to operate and responds quickly, allowing operators to quickly adjust the angle of the side plate 4 according to different specifications of metal parts, significantly improving the flexibility and automation level of the equipment.

[0045] Preferably, the sidewall of the toothed plate 87 protrudes outward to form a protrusion, and the inner wall of the guide groove 89 is provided with a sliding groove that mates with the protrusion.

[0046] A sliding guide fit is achieved between the toothed plate 87 and the guide groove 89. The interlocking structure of the protrusion and the groove can effectively constrain the movement trajectory of the toothed plate 87, prevent the toothed plate 87 from deviating or dislodging during movement, ensure that the toothed plate 87 and the gear 83 always maintain precise meshing, and improve the operational reliability and service life of the rotating assembly.

[0047] Preferably, the air guiding structure includes a first guide block 51, a telescopic hose 52 and a second guide block 53. The first guide block 51 is fixed to the middle of the rear surface of the upright plate 3. The second guide block 53 is arranged side by side with the first guide block 51 to communicate internally through the telescopic hose 52. One end of the second guide block 53 is provided with an air inlet 54.

[0048] The flexible hose 52 is connected between the first guide block 51 and the second guide block 53, which can adapt to the relative displacement or vibration that may exist between the vertical plate 3 and the external air source, and play a role in buffering and flexible connection. At the same time, the air inlet 54 is set at one end of the second guide block 53, which facilitates quick docking with external air supply equipment. The overall structure is compact and the air passage is unobstructed.

[0049] Preferably, the atomizing component 2 includes a spray nozzle 21 and an air inlet pipe 23. The spray nozzle 21 is fixed to the inner wall of the cooling tank 1, and the air inlet pipe 23 is connected to one end of the spray nozzle 21 for air intake. A liquid inlet pipe 22 is provided on the spray nozzle 21, and one end of the liquid inlet pipe 22 is connected to coolant.

[0050] It achieves the function of blowing mist into the inside of the cooling tank 1. The spray nozzle 21 is fixed to the inner wall of the cooling tank 1, the air inlet pipe 23 is used to introduce high-pressure airflow, and the liquid inlet pipe 22 is connected to the coolant. The high-pressure airflow and coolant are mixed and atomized inside the spray nozzle 21 and then sprayed out. The atomization efficiency is high and the droplet size is uniform, which ensures that the metal parts can fully and evenly contact the mist during the pre-cooling stage, so as to achieve a gentle cooling effect.

[0051] Preferably, a second support plate 93 is rotatably connected to the lower surface edge of the side plate 4, and a first support plate 92 is rotatably connected to one end of the second support plate 93 via a rotating shaft. A fixing plate 91 is rotatably connected to one end of the first support plate 92, and the fixing plate 91 is fixedly engaged with the cooling tank 1.

[0052] This provides additional auxiliary support for side plate 4. This structure can deflect accordingly when the angle of side plate 4 is adjusted, always providing support for side plate 4, effectively distributing the load of side plate 4 and the first air nozzle 5, and enhancing the rigidity and stability of the overall structure.

[0053] Preferably, the side plate 4 is symmetrically arranged in two places along the vertical plate 3;

[0054] Dual-sided airflow cooling of metal parts is achieved. The first air nozzles 5, symmetrically arranged on both sides, can simultaneously spray airflow from both sides of the metal parts, forming counter-current cooling, which effectively improves the uniformity of cooling and avoids the problem of uneven cooling on both sides of the metal parts caused by single-sided airflow, further ensuring the dimensional accuracy and performance consistency of the product after quenching.

[0055] Preferably, multiple first air nozzles 5 are provided, and the first air nozzles 5 are arranged in an array along the surface of the vertical plate 3;

[0056] It achieves large-area, multi-angle coverage cooling of metal parts. The array-arranged first air nozzles 5 can make the high-speed airflow act evenly on the surface of the metal parts, avoid cooling dead zones, significantly improve the cooling efficiency in the final cooling stage and the drying effect of the surface coolant, and provide a clean workpiece surface for subsequent processing or assembly processes.

[0057] A method for regulating combined air-mist-water quenching cooling, employing a cooling device, includes the following steps:

[0058] Step A: The quenched metal part is lifted and moved to the upper inner side of the cooling tank 1, without contacting the coolant inside the cooling tank 1. The high-pressure airflow flows into the inner side of the spray nozzle 21 through the air inlet pipe 23. At the same time, the coolant flows into the inner side of the spray nozzle 21 through the liquid inlet pipe 22, is atomized and sprayed out. The high-speed flowing mist comes into contact with the surface of the metal part. By using the high-speed flowing mist sprayed by the atomizing component 2 for pre-cooling, the metal part first comes into contact with room temperature air and a small amount of atomized coolant, achieving gentle cooling. This effectively avoids the severe thermal stress impact caused by direct immersion in the coolant, and controls quenching deformation from the source.

[0059] Step B: After the metal part is cooled by the mist, it is sent into the middle of the inner side of the cooling tank 1 and comes into contact with the cooling liquid inside. At this time, the metal part is wrapped by the coolant and cooled down quickly, which helps to ensure that the metal part obtains the required strengthening phase and mechanical properties.

[0060] Step C: Raise the metal part to the height position corresponding to the first air nozzle 5. The airflow enters the second guide block 53, the telescopic hose 52 and the inner side of the first guide block 51 through the air inlet 54 in sequence, and flows out from the first air nozzle 5 to contact the metal part, thereby achieving final cooling through the airflow and drying the coolant on the surface of the metal part. This facilitates the final cooling through the airflow from the first air nozzle 5, while drying the coolant residue on the surface of the metal part. This achieves uniform cooling to room temperature and provides a clean workpiece surface for subsequent processes.

[0061] Step D: When the metal part is small, the motor 85 drives the lead screw 86 to rotate. The lead screw 86 engages with the ring thread on the toothed plate 87 to drive the toothed plate 87 to move. The toothed plate 87 drives the rotating column 81 to rotate through the gear 83 meshing with it, thereby causing the side plate 4 to rotate toward the position of the metal part. This allows the first air nozzle 5 on the side plate 4 to be better oriented toward the metal part and shorten the distance between it and the metal part, thereby improving the utilization of airflow. This facilitates the electric adjustment of the angle of the side plate 4, allowing the first air nozzle 5 on the side plate 4 to adjust its orientation and distance in real time according to the size of the metal part. This ensures that even small-sized metal parts can obtain efficient and concentrated airflow cooling, improving energy utilization efficiency and the applicability of the equipment.

[0062] This invention overcomes the problems of uncontrollable cooling speed, easy deformation, and poor adaptability of traditional quenching methods by organically combining and segmenting three cooling media: wind, mist, and water. It provides a highly efficient, precise, and adaptable quenching and cooling solution for the field of new energy metal processing.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
