Description

Technical Field

[0001] The present invention relates to the field of aluminum alloy processing, and particularly to a spray cooling device for processing aluminum alloy die-castings. Background Art

[0002] Aluminum alloy die-castings refer to parts made of aluminum alloy, which have advantages such as high manufacturing adaptability and strong variability. During the processing of aluminum alloy die-castings, the cooling operation is crucial. When processing aluminum alloy die-castings, operations such as cutting or grinding will generate a large amount of heat, causing the temperature of the workpiece to rise sharply. Excessive temperature will cause changes in the material properties of the workpiece, such as a decrease in hardness and a change in the metallographic structure, affecting the machining accuracy and surface quality. Cooling prevents uneven thermal expansion of the workpiece due to local overheating, thereby causing thermal stress, avoiding defects such as deformation and cracks, and ensuring the dimensional accuracy and structural integrity of the workpiece.

[0003] In the prior art, a cooling device is proposed in a Chinese patent document with the publication number CN117000978A, a cooling device for engine steel castings, which includes a cooling channel. A water collecting tank is installed at the bottom of the cooling channel. The two ends of the cooling channel are open. A circulating conveyor belt and a loading component are installed in the cooling channel. The loading components are equidistantly installed on the circulating conveyor belt. The loading component is used to place engine steel castings. An induction component is installed in the area between the upper belt body and the lower belt body of the circulating conveyor belt side by side. The induction component is used to sense whether the loading component is loaded with engine steel castings. A spray component is installed above the upper belt body of the circulating conveyor belt side by side, and the positions of the spray component and the induction component correspond one by one. After the induction component senses that the loading component moved to it is loaded with engine steel castings, a transmission part is used to control the spray component to start for spraying cooling water, which can save water resources. At the same time, the whole operation does not require a power-consuming control component, avoiding power failures. On the other hand, the water temperature in each spray component can be set independently, and it is possible to spray cooling water at different temperatures in different stages, better meeting the requirements of the cooling process. However, when this solution is actually used, there are still the following deficiencies: When aluminum alloy die-castings are spray-cooled, due to their high temperature state, once cooling water is sprayed on them, a large amount of water vapor will be generated instantaneously. These water vapors diffuse around the aluminum alloy die-castings. For aluminum alloy die-castings, water vapor will chemically react with elements such as iron in the aluminum alloy die-castings in a high-temperature environment, thereby generating oxide scales. The generation of oxide scales not only affects the surface quality of the aluminum alloy die-castings, making their surfaces rough and reducing the aesthetics, but also in subsequent processing, additional oxide scales need to be removed, increasing the machining allowance and cost. The hydrogen atoms decomposed from water vapor at high temperatures may penetrate into the interior of the aluminum alloy die-castings. The penetration of hydrogen atoms will cause the aluminum alloy die-castings to exhibit hydrogen embrittlement, greatly reducing the toughness and strength of the aluminum alloy die-castings and seriously affecting their service performance and safety. In addition, for components such as cooling pipes and nozzles made of metal materials, a high-humidity environment is extremely likely to cause corrosion. Over time, corrosion will gradually damage the structural integrity of these components, reducing the service life of the cooling device and increasing the equipment maintenance and replacement costs.

[0004] Therefore, the present application provides a spray-cooling device for processing aluminum alloy die-castings to quickly remove the water vapor generated by the hot and cold contact during the spray-cooling of aluminum alloy die-castings. Summary of the Invention

[0009] Further, a water storage tank is arranged at the bottom of the conveying frame. A conveying pipe is arranged on the side of the water storage tank.

The bottom end of the folded pipe is fixedly connected to the upper surface of the water storage tank.

[0010] Further, the spraying mechanism includes an opening and closing assembly arranged in the middle of the conveying frame and a swinging assembly arranged below the hollow pipe.

[0011] Further, the opening and closing assembly includes a top plate fixedly connected to the middle of the inner side of the conveying frame. A central rod is rotatably connected to the middle of the upper surface of the top plate. A driven wheel II is fixedly connected to the top of the central rod. The outer surface of the driven wheel II is meshed and connected with the driving wheel. A semi-gear is fixedly sleeved on the outer surface of the bottom end of the central rod. A vertical rod is movably inserted through the upper surface of the top plate. A full gear is fixedly sleeved on the top of the vertical rod. There are two full gears and they are symmetrically distributed on both sides of the semi-gear. The semi-gear is meshed with the two full gears alternately.

[0012] Further, a plug rod is movably connected to the upper surface of the full gear. A side pipe is arranged on the outer surface of the conveying pipe near the connection with the hollow pipe. A piston is slidably connected inside the side pipe. One end of the plug rod far away from the full gear is hinged to the end of the piston.

[0013] Further, the swinging assembly includes a spray pipe arranged below the hollow pipe. A corrugated pipe is arranged at the connection between the spray pipe and the hollow pipe. A chute is formed on the lower surface of the top plate. A slider is slidably limited inside the chute. A strip-shaped plate is fixedly connected to the bottom end of the slider.

[0016] Advantages of the present invention: 1. By designing a dispersing component, when a large amount of water vapor is generated when the cooling water contacts the aluminum alloy die-casting, the fan blades can be quickly rotated driven by the motor, sucking the water vapor into the folded tube, cooling it by heat absorption through the heat sink and then entering the water storage tank, ensuring that the temperature of the water vapor entering the water storage tank drops, realizing the dispersion of the water vapor and recycling the water vapor at the same time.

[0017] 2. By designing a compression component, while dispersing and sucking in the water vapor, the up and down movement of the pressing block is realized by the rotation of the eccentric wheel. When the pressing block moves upward, it can suck in the water vapor, and when it moves downward, it can pressurize the water vapor in the folded tube. Pressurization can accelerate the liquefaction of the water vapor into water, improve the liquefaction speed of the water vapor, reduce the amount of water vapor flowing out of the folded tube, and thus improve the dispersion efficiency.

[0018] 3. By designing an opening and closing component, the motor drive and the transmission of the driven wheel II can realize the alternating rotation of the half gear driving two full gears. During the process of the full gear rotating half a turn, the piston in the side tube will be pulled or pushed by the plug rod on its upper surface, so that the piston can enter the delivery tube from the side tube or slide from the delivery tube into the side tube. In this way, alternatingly reducing the cooling water discharge can reduce the flow rate of the cooling water while ensuring the cooling effect, achieving the effect of saving cooling water.

[0019] 4. By designing a spraying component, the vertical rod is used as a transmission structure to drive the convex block to rotate. The convex block pushes the strip plate to move and then pushes the strip plate to move in the reverse direction under the elastic force of the spring, thus realizing the reciprocating swing of the spraying tube, expanding the spraying range of the spraying tube, ensuring the all-round spraying cooling of the outer surface of the aluminum alloy die-casting, and improving the cooling efficiency.

Specific embodiments

[0023] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0024] Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation to this patent; in order to better illustrate the embodiments of the present invention, some components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product.

[0025] The present invention provides a technical solution. Referring to Figures 1 to 9 as shown, an aluminum alloy die-casting part processing spray cooling device includes a conveying frame 1, and a dispersing component and a spraying mechanism are arranged on the upper part of the conveying frame 1; The dispersing assembly includes a motor 201 arranged at the top of the conveying frame 1, a driving end of the motor 201 is fixedly connected to a driving wheel 202, a transmission rod 203 is movably arranged on the upper part of the conveying frame 1, and one end of the transmission rod 203 close to the middle of the conveying frame 1 is fixedly connected to a driven wheel 204, the driving wheel 202 is meshedly connected with the driven wheel 204, a folding tube 205 is arranged on the side of the conveying frame 1, and a trumpet tube 206 is arranged at one end of the folding tube 205 close to the inside of the conveying frame 1, and the folding tube 205 is provided with a horn tube 206. A straight rod 207 is movably inserted in the middle, and one end of the straight rod 207 extending into the horn tube 206 is fixedly connected with a fan blade 208. The end of the transmission rod 203 away from the conveyor frame 1 is fixedly sleeved with a pulley 1 209, and the end of the straight rod 207 extending out of the folding tube 205 is fixedly sleeved with a pulley 210. The pulley 1 209 is meshed and connected with the pulley 2 210 through a belt 211. The outer surface of the folding tube 205 is distributed with a ring matrix with heat sinks 212, and the upper part of the folding tube 205 is provided with a compression assembly; The motor 201 drives the driving wheel 202 to rotate, and the driving wheel 202 synchronously drives the driven wheel 204 to rotate and drives the transmission rod 203 to rotate, and then through the transmission of the pulley 1 209 and the pulley 2 210, the straight rod 207 is successfully driven to rotate, and then the fan blades 208 can be driven to rotate and water vapor is sucked into the folding tube 205. The design of the trumpet tube 206 can expand the suction range. The water vapor sucked into the folding tube 205 will flow into the water tank 4, and will be absorbed and cooled by the heat sink 212, ensuring that the temperature of the water vapor entering the water tank 4 is cooled, and the water vapor is not only dissipated but also recycled and reused.

[0026] Reference Figures 2 to 4 As shown, the compression assembly includes an eccentric wheel 301 fixedly sleeved on the outer surface of the transmission rod 203, an extension tube 302 is fixedly connected to the top bending part of the folding tube 205, a pressing block 303 is slidably connected inside the extension tube 302, a pull rod 304 is fixedly connected to the top of the pressing block 303, a limiting groove 305 is provided on the outer surface of the eccentric wheel 301, and the top end of the pull rod 304 is limited and slidable inside the limiting groove 305; When the transmission rod 203 rotates, it will also drive the eccentric wheel 301 to rotate around it. Since the pull rod 304 is slidably engaged in the limit groove 305 on the outer surface of the eccentric wheel 301, the pull rod 304 will drive the pressure block 303 to slide up and down in the extension tube 302 during the rotation of the eccentric wheel 301. The upward movement of the pressure block 303 can inhale water vapor, and the water vapor in the folding tube 205 can be pressurized during the downward pressure. According to the relevant principles of the ideal gas state equation and the Clausius-Clapeyron equation, it can be known that pressurization can accelerate the liquefaction of water vapor into water, increase the liquefaction rate of water vapor, and reduce the amount of water vapor flowing out of the folding tube 205, thereby improving the dissipation efficiency.

[0027] Reference Figures 1 to 9As shown in the figure, a water storage tank 4 is provided at the bottom of the conveying frame 1. A conveying pipe 5 is provided on the side of the water storage tank 4. A hollow pipe 6 is provided in the middle of the conveying frame 1. One end of the conveying pipe 5 away from the water storage tank 4 is bifurcated and connected to the middle of the hollow pipe 6. The bottom end of the folded pipe 205 is fixedly connected to the upper surface of the water storage tank 4. The spraying mechanism includes an opening and closing assembly provided in the middle of the conveying frame 1 and a swinging assembly provided below the hollow pipe 6. When the aluminum alloy die-casting moves to the cooling device, the conveying pipe 5 conveys the cooling water in the water storage tank 4 into the hollow pipe 6, and then sprays it through the spraying mechanism to realize the spray cooling of the aluminum alloy die-casting.

[0028] Refer to Figure 5 and Figure 8 As shown in the figure, the opening and closing assembly includes a top plate 701 fixedly connected to the middle of the inner side of the conveying frame 1. A central rod 702 is rotatably connected to the middle of the upper surface of the top plate 701. A driven wheel two 703 is fixedly connected to the top end of the central rod 702. The outer surface of the driven wheel two 703 is meshed and connected with the driving wheel 202. A semi-gear 704 is fixedly sleeved on the outer surface of the bottom end of the central rod 702. A vertical rod 705 is movably inserted through the upper surface of the top plate 701. A full gear 706 is fixedly sleeved on the top end of the vertical rod 705. There are two full gears 706 and they are symmetrically distributed on both sides of the semi-gear 704. The semi-gear 704 is meshed with the two full gears 706 in a staggered manner. The number of tooth blocks of the semi-gear 704 is half of that of the full gear 706. A plug rod 707 is movably connected to the upper surface of the full gear 706. A side pipe 708 is provided on the outer surface of the conveying pipe 5 near the connection with the hollow pipe 6. A piston 709 is slidably connected inside the side pipe 708. One end of the plug rod 707 away from the full gear 706 is hinged to the end of the piston 709. During the rotation of the driving wheel 202, it will also drive the driven wheel two 703 to rotate, and then drive the semi-gear 704 to rotate through the transmission of the central rod 702. Since two full gears 706 are symmetrically arranged on both sides of the semi-gear 704, during the rotation of the semi-gear 704, it will be meshed with the two full gears 706 in a staggered manner and indirectly drive the full gears 706 to rotate. When the semi-gear 704 rotates one circle, it will drive the full gear 706 to rotate half a circle. During the process of the full gear 706 rotating half a circle, it will pull or push the piston 709 in the side pipe 708 through the plug rod 707 on its upper surface. Thus, it can make the piston 709 enter the conveying pipe 5 from the side pipe 708 or slide from the conveying pipe 5 into the side pipe 708. In this way, the smoothness of the conveying pipe 5 and the two hollow pipes 6 is different. When the piston 709 is in the side pipe 708, the cooling water in the conveying pipe 5 enters the hollow pipe 6 without obstruction and sprays for cooling. When the piston 709 is in the conveying pipe 5, it will block the cooling water to a certain extent, and then reduce the cooling water entering the hollow pipe 6, thereby reducing the cooling water volume sprayed. In this way, alternately reducing the cooling water discharge can reduce the flow rate of the cooling water while ensuring the cooling effect, achieving the effect of saving cooling water.

[0029] Referring to Figures 6 to 9 As shown, the swinging assembly includes a spray pipe 801 arranged at the lower part of the hollow pipe 6. A corrugated pipe 802 is arranged at the connection between the spray pipe 801 and the hollow pipe 6. A chute 803 is formed on the lower surface of the top plate 701. A slider 804 is limited to slide inside the chute 803. The bottom end of the slider 804 is fixedly connected to a strip plate 805. The middle part of the side of the strip plate 805 is fixedly connected to a side plate 806. A spring 812 is arranged inside the chute 803. One end of the spring 812 abuts against the inner wall of the chute 803, and the other end abuts against the outer surface of the slider 804. The bottom end of the vertical rod 705 is fixedly connected to a convex block 807. The outer surface of the convex block 807 abuts against the outer surface of the side. A swing rod 808 is fixedly connected to the outer surface of the spray pipe 801. A track 809 is formed through the outer surface of the strip plate 805. The swing rod 808 extends into the track 809. A shaft rod 810 is arranged inside the track 809. A through hole 811 is formed through the outer surface of the swing rod 808. The shaft rod 810 is slidably connected inside the through hole 811; During the rotation of the spur gear 706, the convex block 807 will be driven by the vertical rod 705 to perform a circular motion around the vertical rod 705. During the rotation of the convex block 807, the side will be toggled to drive the strip plate 805 to slide along the chute 803. At the same time, the slider 804 slides inside the chute 803 and compresses or stretches the spring 812. The movement of the strip plate 805 will drive the swing rod 808 to deflect along the track 809. And the spray pipe 801 and the hollow pipe 6 are connected by the corrugated pipe 802. Therefore, the deflection of the swing rod 808 will drive the spray pipe 801 to swing. Since the vertical rod 705 stops after rotating half a circle, at this time the convex block 807 is separated from the side, and the spring 812 rebounds to drive the strip plate 805 to move in the opposite direction, and then drives the spray pipe 801 to swing to the other side again. In this way, the reciprocating swing of the spray pipe 801 is realized, the spraying range of the spray pipe 801 is enlarged, the full - range spraying and cooling of the outer surface of the aluminum alloy die - casting is ensured, and the cooling efficiency is improved.

[0030] Working principle of the present invention: The aluminum alloy die-castings after production are moved in position through the conveyor belt on the conveying rack 1. When the aluminum alloy die-castings move to the cooling device, the conveying pipe 5 conveys the cooling water in the water storage tank 4 into the hollow pipe 6, and then sprays it through the spray pipe 801 to achieve spray cooling of the aluminum alloy die-castings. At this time, because the aluminum alloy die-castings are in a high-temperature state, a large amount of water vapor will be instantly generated when the cooling water is sprayed on. These water vapors diffuse around the aluminum alloy die-castings. The motor 201 operates to drive the driving wheel 202 to rotate. The driving wheel 202 synchronously drives the first driven wheel 204 to rotate and drives the transmission rod 203 to rotate. Then, through the transmission of the first belt wheel 209 and the second belt wheel 210, the straight rod 207 is successfully driven to rotate, and further the fan blade 208 can be driven to rotate and suck the water vapor into the folded pipe 205. The design of the horn pipe 206 can expand the suction range. The water vapor sucked into the folded pipe 205 will flow into the water storage tank 4 and will be cooled by absorbing heat after passing through the heat sink 212, ensuring that the temperature of the water vapor entering the water storage tank 4 is reduced, realizing the dispersion of the water vapor and at the same time recycling and reusing the water vapor. When the transmission rod 203 rotates, it will also drive the eccentric wheel 301 to rotate around it. Since the pull rod 304 is slidably clamped in the limiting groove 305 on the outer surface of the eccentric wheel 301, during the rotation of the eccentric wheel 301, the pressing block 303 will be driven by the pull rod 304 to slide up and down in the extension pipe 302. When the pressing block 303 moves up, it can suck in the water vapor, and when it moves down, it can pressurize the water vapor in the folded pipe 205. According to the relevant principles of the ideal gas state equation and the Clausius-Clapeyron equation, it can be known that pressurization can accelerate the liquefaction of water vapor into water, increase the liquefaction speed of water vapor, reduce the amount of water vapor flowing out of the folded pipe 205, and thus improve the dispersion efficiency; During the rotation of the driving wheel 202, it will also drive the second driven wheel 703 to operate, and then drive the half gear 704 to rotate through the transmission of the central rod 702. Since two full gears 706 are symmetrically arranged on both sides of the half gear 704, during the rotation of the half gear 704, it will alternately engage with the two full gears 706 and indirectly drive the full gears 706 to rotate. The number of teeth of the half gear 704 is half of that of the full gear 706. Therefore, when the half gear 704 rotates one circle, it will drive the full gear 706 to rotate half a circle. During the half-circle rotation of the full gear 706, the piston rod 707 on its upper surface will pull or push the piston 709 in the side pipe 708, so that the piston 709 can enter the conveying pipe 5 from the side pipe 708 or slide from the conveying pipe 5 into the side pipe 708. In this way, the smoothness of the conveying pipe 5 and the two hollow pipes 6 is different. When the piston 709 is in the side pipe 708, the cooling water in the conveying pipe 5 enters the hollow pipe 6 without obstruction and is sprayed for cooling. When the piston 709 is in the conveying pipe 5, it will block the cooling water to a certain extent, thereby reducing the cooling water entering the hollow pipe 6 and reducing the sprayed cooling water volume. Because continuous spraying will cause the cooling water to flow along the surface of the aluminum alloy die-casting, the improvement of the cooling effect is not significant. Thus, alternately reducing the cooling water discharge can reduce the cooling water flow while ensuring the cooling effect, achieving the effect of saving cooling water. During the rotation of the full gear 706, the vertical rod 705 will drive the convex block 807 to perform a circular motion around the vertical rod 705. During the rotation of the convex block 807, it will push the side, thereby driving the strip plate 805 to slide along the chute 803. At the same time, the slider 804 slides inside the chute 803 and squeezes or stretches the spring 812. The movement of the strip plate 805 will drive the swing rod 808 to deflect along the track 809, and the spray pipe 801 and the hollow pipe 6 are connected by a corrugated pipe 802. Therefore, the deflection of the swing rod 808 will drive the spray pipe 801 to swing. Since the vertical rod 705 will stop after rotating half a circle, at this time the convex block 807 is separated from the side, and the spring 812 rebounds to drive the strip plate 805 to move in the opposite direction, thereby driving the spray pipe 801 to swing to the other side again. In this way, the reciprocating swing of the spray pipe 801 is realized, expanding the spraying range of the spray pipe 801, ensuring the all-round spray cooling of the outer surface of the aluminum alloy die-casting, and improving the cooling efficiency.
