Description

Technical Field

[0001] This utility model relates to the technical field of casting cooling devices, and in particular to a cooling device for alloy casting forming. Background Technology

[0002] In the field of alloy casting forming and processing, the cooling process is a key link that determines the mechanical properties, dimensional accuracy and surface quality of the casting. Existing cooling devices are mostly based on cooling boxes and spray components as the core structure, and achieve cooling by spraying coolant onto the surface of the casting.

[0003] However, in actual use, existing cooling devices are mostly fixed or unidirectional moving designs. Roll castings are often transported by conveyor belts during the cooling process, and the contact surface between the casting and the conveyor belt is always blocked. Since the spray assembly cannot adapt to the movement and posture adjustment of the casting, the coolant can only cover the upper surface and sides of the casting. The contact surface can never be covered by the spray, forming a cooling blind zone. This situation of local inadequate cooling will lead to a large temperature gradient difference in the overall temperature of the roll casting, which not only affects the cooling quality, but may also cause uneven internal structure of the casting due to local overheating, reducing the mechanical properties of the product. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cooling device for alloy casting forming. It solves the technical problem that in existing technologies, the spray assembly cannot adapt to the movement and posture adjustment of the casting, resulting in coolant only covering the upper surface and sides of the casting, leaving the contact surface uncovered and creating a cooling blind zone that affects cooling quality. This new device achieves all-around spray cooling of the roll casting, resolving the difficulty of the spray assembly to perform all-around spraying on the roll casting, making it difficult to spray the side of the roll casting in contact with the transmission belt. This satisfies the requirements for using roll castings and achieves the goal of improving the cooling quality of the roll casting.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cooling device for alloy casting forming, comprising a cooling box and a spray assembly disposed inside the cooling box, wherein a rotating assembly is disposed inside the cooling box, the rotating assembly comprising drive rollers symmetrically disposed on both sides inside the cooling box to drive the roller casting to rotate, and support bases and fixing seats are disposed on the outer walls at both ends of the cooling box to support the ends of the two sets of drive rollers. The bottom of the cooling tank is fixedly equipped with a coolant tank that provides water for the spray assembly. A filter screen plate for filtering impurities is fixedly installed at the top opening of the coolant tank. A waste collection box is provided at the discharge port at the end of the filter screen plate, and a cleaning scraper is slidably connected to the top of the filter screen plate to clean impurities into the waste collection box.

[0006] Preferably, the spray assembly includes a drive frame slidably connected to the inner peripheral wall of the cooling box, a circulating water pump is fixedly installed on the top of the drive frame, and water pipe one and water pipe two are fixedly installed at the inlet and outlet ends of the circulating water pump, respectively.

[0007] Preferably, the water pipe is fixedly installed on the top wall inside the drive frame, and multiple sets of high-pressure nozzles are fixedly installed at the bottom of the water pipe. The bottom end of the water pipe passes through the top of the coolant tank and is inserted into it.

[0008] Preferably, the ends of the two sets of drive rollers rotate between two sets of fixed seats, and a first motor that drives the drive rollers to rotate is fixedly installed on the outer wall of one set of fixed seats.

[0009] Preferably, the outer wall of the cooling box is provided with a drive assembly that simultaneously drives the spray assembly and the cleaning scraper to slide. The cleaning scraper is located on one side of the drive frame and is fixedly connected to the drive frame by multiple sets of fixing rods.

[0010] Preferably, the drive assembly includes a fixed frame fixedly installed on the outer wall of the cooling box, a transmission screw rotatably connected inside the fixed frame, a drive component slidably connected to the fixed frame and threaded on the outer peripheral wall of the transmission screw, the end of the drive component passing through the outer wall of the cooling box and fixedly connected to the drive frame, and a second motor that drives the transmission screw to rotate is fixedly installed on the outer wall of the fixed frame.

[0011] Preferably, the end of the waste collection box passes through the interior of the support base and is fixedly mounted with an mounting plate, which is attached to the outer wall of the support base.

[0012] By employing the above technical solution, this utility model provides a cooling device for alloy casting, which has at least the following beneficial effects: 1. This utility model, by setting a rotating component inside the cooling box to drive the roller casting to rotate, and setting a spray component that moves along the length of the roller casting, can perform all-round spray cooling of the roller casting when the rotating component and the movable spray component are used together. This solves the problem that the spray component is difficult to spray the roller casting in all directions, making it difficult to spray the side of the roller casting that is in contact with the transmission belt. This satisfies the requirements of the roller casting for use and achieves the cooling quality of the roller casting.

[0013] 2. This utility model sets a coolant tank at the bottom of the cooling box and installs a filter screen plate on the top of the coolant tank. The cleaning scraper on the top of the filter screen plate is connected to the spray assembly and the same set of drive components.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Based on the existing problem that the spray assembly 2 cannot adapt to the movement and posture adjustment of the casting, the coolant can only cover the upper surface and sides of the casting, leaving the contact surface uncovered and forming a cooling blind zone, thus affecting the cooling quality, this embodiment provides a cooling device for alloy casting forming. This device can perform all-around spray cooling on the roll casting, solving the problem that the spray assembly 2 cannot perform all-around spraying on the roll casting, making it difficult to spray the side of the roll casting in contact with the transmission belt. This satisfies the requirements for using the roll casting and achieves the goal of improving the cooling quality of the roll casting. Please refer to... Figure 1 - Figure 5 The cooling device for alloy casting includes a cooling box 1 and a spray assembly 2 installed inside the cooling box 1. The cooling box 1 is equipped with a rotating assembly 3, which includes drive rollers 33 symmetrically arranged on both sides inside the cooling box 1 to drive the roll casting to rotate. The outer walls at both ends of the cooling box 1 are provided with support bases 31 and fixed seats 32 to support the ends of the two sets of drive rollers 33. When cooling the roll casting, the heated roll casting is first hoisted and placed on top of the two sets of drive rollers 33 by a hoisting device. Then, the spray assembly 2 can spray the roll casting to cool it thoroughly during the rotation process, thereby improving the cooling quality of the roll casting.

[0019] Because the roller castings are conveyed to the cooling box 1 via a transmission belt, and because the roller castings remain stationary, the spray assembly 2 cannot perform omnidirectional spraying on them. This makes it difficult to spray the side of the roller castings in contact with the transmission belt. By combining the rotating assembly 3 with a moving spray system, omnidirectional spraying of the roller castings can be achieved. Figure 1 - Figure 3 As shown, a coolant tank 4, which provides water to the spray assembly 2, is fixedly installed at the bottom of the cooling tank 1. A filter screen 5 for filtering impurities is fixedly installed at the top opening of the coolant tank 4. A waste collection box 7 is provided at the discharge port at the end of the filter screen 5. A cleaning scraper 6 is slidably connected to the top of the filter screen 5 to clean impurities into the waste collection box 7. During the moving spray cooling process, impurities inside the coolant can be filtered through the filter screen 5 to ensure that there are no impurities in the coolant entering the coolant tank 4. At the same time, the cleaning scraper 6 can clean the impurities filtered on the top of the filter screen 5 and scrape them into the waste collection box 7 for centralized collection, ensuring the effectiveness of the filter screen 5.

[0020] The spray assembly 2 includes a drive frame 21 that is slidably connected to the inner peripheral wall of the cooling tank 1. A circulating water pump 22 is fixedly installed on the top of the drive frame 21. Water pipe 231 and water pipe 41 are fixedly installed at the inlet and outlet of the circulating water pump 22, respectively. When the circulating water pump 22 is started, the water pipe 41 at the circulating water pump 22 draws out the coolant inside the coolant tank 4 and sprays the coolant out through the water pipe 231 and multiple sets of high-pressure nozzles 23, so that the sprayed coolant cools down the surface of the rotating roller casting, thereby achieving the purpose of coolant circulation.

[0021] To meet usage requirements, water pipe 231 is fixedly installed on the top wall inside the drive frame 21. Multiple high-pressure nozzles 23 are fixedly installed at the bottom of water pipe 231. The bottom end of water pipe 231 passes through the top of the coolant tank 4 and is inserted into it. When the drive frame 21 drives water pipe 41 to slide, the bottom end of water pipe 41 is always inside the coolant tank 4, so it can always maintain the connection state and always make the coolant tank 4 supply coolant to the spray assembly 2.

[0022] Example 2 Based on Example 1, such as Figure 3 - Figure 6 As shown, the device is also equipped with a drive assembly that synchronously drives the spray assembly 2 and the cleaning scraper 6 to slide. During the spraying process, the spray assembly 2 can simultaneously drive the cleaning scraper 6 to slide on the top of the roller casting to clean the filtered impurities, thereby reducing the operating cost of the equipment. The ends of the two sets of drive rollers 33 rotate between the two sets of fixed seats 32. The outer wall of one set of fixed seats 32 is fixedly installed with a first motor 34 that drives the drive rollers 33 to rotate. By starting the first motor 34, the drive rollers 33 can be driven to rotate inside the cooling box 1. Since the roller casting is located between the two sets of drive rollers 33, the roller casting can be driven to rotate between the two sets of drive rollers 33, so that the outer peripheral wall of the roller casting rotates at the bottom of multiple sets of high-pressure nozzles 23, and the roller casting is sprayed and cooled comprehensively.

[0023] To ensure the synchronization of the spray assembly 2 and the cleaning scraper 6, and to reduce equipment operating costs, such as Figure 5 - Figure 6 As shown, the outer wall of the cooling box 1 is equipped with a drive assembly that simultaneously drives the spray assembly 2 and the cleaning scraper 6 to slide. The cleaning scraper 6 is located on one side of the drive frame 21 and is fixedly connected to the drive frame 21 by multiple sets of fixing rods 61. The bottom end of the cleaning scraper 6 is in contact with the top of the filter screen plate 5. During the process of the drive frame 21 driving multiple sets of high-pressure nozzles 23 to slide along the length direction of the roller casting, the multiple sets of fixing rods 61 can simultaneously drive the cleaning scraper 6 to slide on the top of the filter screen plate 5 to clean the impurities filtered on the top of the filter screen plate 5.

[0024] Because some iron impurities remain on the surface of the heated casting, these impurities are easily washed away with the coolant during the spray cooling process. To better remove these impurities, such as... Figure 4 - Figure 6As shown, the drive assembly includes a fixed frame 8 fixedly installed on the outer wall of the cooling box 1. A transmission screw 82 is rotatably connected inside the fixed frame 8. A drive component 83, which is slidably connected to the fixed frame 8, is threaded onto the outer peripheral wall of the transmission screw 82. The end of the drive component 83 passes through the outer wall of the cooling box 1 and is fixedly connected to the drive frame 21. A second motor 81, which drives the transmission screw 82 to rotate, is fixedly installed on the outer wall of the fixed frame 8. By starting the second motor 81, the transmission screw 82 rotates inside the fixed frame 8, causing the drive component 83 to drive the drive frame 21 to slide on the outer peripheral wall of the roller casting. This causes multiple sets of high-pressure nozzles 23 to slide along the length of the roller casting. In conjunction with the rotation of the roller casting, the roller casting can be sprayed and cooled comprehensively. The cleaning scraper 6 pushes the impurities filtered from the top of the filter screen 5 into the waste collection box 7 for cleaning, preventing impurities from clogging the filter screen 5 and affecting the flow of coolant.

[0025] To better clean up the collected impurities, the waste collection bin 7 is designed with a detachable mounting mechanism, such as... Figure 3 - Figure 5 As shown, the end of the waste collection box 7 passes through the inside of the support base 31 and is fixedly installed with an mounting plate 71. The mounting plate 71 is attached to the outer wall of the support base 31. Pulling the mounting plate 71 outward will cause the waste collection box 7 to slide inside the support base 31 and be pulled out to clean the impurities collected inside the waste collection box 7.
