Description

Technical Field

[0001] This utility model belongs to the technical field of magnesium alloy sheet technology, and in particular relates to a device for preventing high-temperature oxidation of magnesium alloy sheets. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements added. Their characteristics include: low density, high strength, high elastic modulus, good heat dissipation, good vibration damping, greater impact load capacity than aluminum alloys, good resistance to organic matter and alkali corrosion, good damping performance, and environmental friendliness. The main alloying elements include aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. Currently, magnesium-aluminum alloys are the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Due to these advantages, magnesium alloys have become one of the most promising metallic structural materials, mainly used in aerospace, transportation, chemical, and rocket industries.

[0003] Magnesium alloy sheets are prone to oxidation at high temperatures, which affects their performance. To prevent this oxidation, high-temperature oxidation protection devices are needed for storage. Currently, magnesium alloy sheets are typically stored in warehouses without proper high-temperature and moisture protection, which allows them to oxidize.

[0004] To address this issue, we provide a high-temperature oxidation prevention device for magnesium alloy plates. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature oxidation prevention device for magnesium alloy plates. By combining the high-temperature oxidation prevention component and the feeding component, it solves the problem in the prior art that magnesium alloy plates do not have a dedicated high-temperature oxidation prevention component to avoid oxidation reactions.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a high-temperature oxidation prevention device for magnesium alloy plates, comprising a high-temperature oxidation prevention component. A pushing component is fixedly connected to the inner cavity of the high-temperature oxidation prevention component. The high-temperature oxidation prevention component includes an outer shell, a support plate fixedly connected to the inner wall of the outer shell, and an inner liner fixedly connected to the other end of the support plate. A vacuum valve is connected to the top of the inner liner, and a support roller is fixedly connected to the inner wall of the inner liner via a bearing. A magnesium alloy plate is placed on the top of the support roller. A one-way electromagnetic water inlet valve is connected to the top of one side of the outer shell, and a one-way electromagnetic drain valve is connected to the bottom of the other side of the outer shell. The pushing component includes a groove formed on the inner wall of the outer shell and located on the back of the magnesium alloy plate. A pushing plate is fitted into the inner cavity of the groove. Lead screws are threaded to both sides of the surface of the pushing plate. The rear end of the lead screws extends through to the back of the inner liner and is fixedly connected to a driven bevel gear. A driving bevel gear meshes with the surface of the driven bevel gear. A transmission shaft is fixedly connected between the two driving bevel gears. A worm gear is fixedly connected to the surface of the transmission shaft, and a worm is meshed with the surface of the worm gear. A motor is fixedly connected to the top of the worm.

[0008] The present invention is further provided that each of the four corners of the bottom of the outer shell is fixedly connected to a pad, and the bottom of the pad is provided with anti-slip texture. The pad can raise the bottom of the device and prevent the outer shell from directly contacting the ground and getting damp. The anti-slip texture on the bottom of the pad can increase the friction with the ground, prevent the device from sliding during placement or operation, and improve the overall placement stability of the device.

[0009] The present invention is further configured such that a sealing door is fixedly connected to the surface of the inner liner by bolts, and a controller is fixedly connected to the surface of the sealing door. The sealing door can open or close the inner liner to facilitate the insertion or removal of magnesium alloy plates. At the same time, when closed, it can ensure the sealing of the inner liner and prevent external air from entering and damaging the internal protective environment. The controller on the surface of the sealing door can centrally control the operation of components such as the one-way electromagnetic water inlet valve, drain valve, and motor, simplifying the operation process and improving the ease of use.

[0010] The present invention is further configured such that the inner liner is made of copper-aluminum alloy. Copper-aluminum alloy has good thermal conductivity, which can quickly transfer the temperature of the cooling medium to regulate the temperature of the inner liner. At the same time, it has strong high temperature resistance, which can adapt to long-term use in high-temperature environments and extend the service life of the inner liner.

[0011] The present invention is further configured such that the front end of the lead screw is fixedly connected to the inner wall of the inner liner through a bearing seat. The bearing seat can provide positioning support for the front end of the lead screw, reduce the shaking when the lead screw rotates, ensure the thread fit accuracy between the lead screw and the push plate, and thus improve the stability of the push plate movement and the accuracy of pushing the material.

[0012] The present invention is further configured such that the inner wall of the inner liner and both sides of the groove cavity are provided with round holes for the lead screw to pass through, and the lead screw is fixedly connected to the round holes by bearings. A shaft seal is provided at the gap between the lead screw and the round holes. The round holes provide a through channel for the lead screw to ensure smooth rotation of the lead screw. The shaft seal between the round holes and the lead screw can seal the gap between the two to prevent the cooling medium between the outer shell and the inner liner from leaking and to maintain the stability of the internal environment of the inner liner.

[0013] The present invention is further configured such that both ends of the transmission shaft are fixedly connected to the back of the inner liner through bearing seats. The bearing seats can limit the axial and radial displacement of the transmission shaft, ensuring that the transmission shaft remains stable during rotation.

[0014] The present invention is further configured such that a mounting base is fixedly connected to the surface of the motor, and the bottom of the mounting base is fixedly connected to the top of the inner liner. The mounting base fixes the motor to the top of the inner liner, which can reduce the vibration generated by the motor during operation from being transmitted to the inner liner or the outer shell, reduce the impact of vibration on the sheet metal, enhance the installation stability of the motor, and extend the service life of the motor.

[0015] The present invention has the following beneficial effects.

[0016] 1. The outer shell of this utility model serves as an outer protective layer, which can isolate external environmental interference. The inner liner, combined with the support plate for stable fixation, forms an independent internal protective space. The vacuum valve works in conjunction with the external vacuum pump to create a vacuum environment in the inner liner, preventing the board from contacting oxygen and causing oxidation. The one-way electromagnetic water inlet valve works in conjunction with the drain valve to regulate the temperature between the inner liner and the outer shell through the circulation of cooling medium, preventing high temperature from causing oxidation of the board.

[0017] 2. The motor of this utility model transmits power through a worm gear and a worm wheel. The worm wheel and the transmission shaft work together to drive two active bevel gears to rotate synchronously. In turn, the driven bevel gear drives the lead screw to rotate, so that the push plate moves smoothly along the lead screw axis, realizing the automated pushing of magnesium alloy plates. No manual close-range operation is required, which reduces labor intensity and reduces the interference of the external environment on the plates, significantly improving operating efficiency and the safety of plate storage.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-6 This utility model relates to a high-temperature oxidation prevention device for magnesium alloy plates, comprising a high-temperature oxidation prevention component 1, a pushing component 2 fixedly connected to the inner cavity of the high-temperature oxidation prevention component 1, a shell 11, a support plate 12 fixedly connected to the inner wall of the shell 11, an inner liner 13 fixedly connected to the other end of the support plate 12, a vacuum valve 14 connected to the top of the inner liner 13, a support roller 15 fixedly connected to the inner wall of the inner liner 13 via a bearing, a magnesium alloy plate placed on the top of the support roller 15, a one-way electromagnetic water inlet valve 16 connected to the top of one side of the shell 11, and a connection to the bottom of the other side of the shell 11. The device includes a one-way electromagnetic drain valve 17 and a pusher assembly 2, which includes a groove formed on the inner wall of the outer shell 11 and located on the back of the magnesium alloy plate. A pusher plate 21 is fitted into the inner cavity of the groove. Both sides of the surface of the pusher plate 21 are threaded with lead screws 22. The rear end of the lead screw 22 extends through to the back of the inner liner 13 and is fixedly connected to a driven bevel gear 23. A drive bevel gear 24 meshes with the surface of the driven bevel gear 23. A drive shaft 25 is fixedly connected between the two drive bevel gears 24. A worm gear 26 is fixedly connected to the surface of the drive shaft 25. A worm 27 meshes with the surface of the worm gear 26. A motor 28 is fixedly connected to the top of the worm 27.

[0028] Specifically: A temperature sensor is fixedly connected to the inner wall of the inner liner 13. The temperature sensor monitors the temperature of the inner cavity of the inner liner 13 in real time. The controller 19 adjusts the opening and closing of the one-way electromagnetic water inlet valve 16 and the one-way electromagnetic drain valve 17 in real time based on the value detected by the temperature sensor. This adjusts the flow rate to control the temperature and prevent the effects of high temperature.

[0029] Each of the four corners of the bottom of the outer casing 11 is fixedly connected to a pad. The bottom of the pad is provided with anti-slip texture. The pad can raise the bottom of the device and prevent the outer casing 11 from directly contacting the ground and getting wet. The anti-slip texture on the bottom of the pad can increase the friction with the ground, prevent the device from sliding during placement or operation, and improve the overall placement stability of the device.

[0030] A sealing door 18 is bolted to the surface of the inner liner 13. A controller 19 is fixedly connected to the surface of the sealing door 18. The sealing door 18 can open or close the inner liner 13, facilitating the insertion or removal of magnesium alloy sheets. When closed, it ensures the airtightness of the inner liner 13, preventing external air from entering and damaging the internal protective environment. The controller 19 on the surface of the sealing door 18 can centrally control the operation of components such as the one-way electromagnetic water inlet valve 16, drain valve, and motor 28, simplifying the operation process and improving ease of use. The inner liner 13 is made of copper-aluminum alloy. Copper-aluminum alloy has good thermal conductivity, which can quickly transfer the temperature of the cooling medium to regulate the temperature of the inner liner 13. It also has strong high-temperature resistance, which can adapt to long-term use in high-temperature environments and extend the service life of the inner liner 13. The front end of the lead screw 22 is fixedly connected to the inner wall of the inner liner 13 through a bearing seat. The bearing seat can position and support the front end of the lead screw 22, reducing the shaking of the lead screw 22 during rotation, ensuring the thread fit accuracy between the lead screw 22 and the push plate 21, thereby improving the smoothness of the push plate 21's movement and the accuracy of material pushing. The inner wall of the inner liner 13 has circular holes on both sides of the groove cavity for the lead screw 22 to pass through. The lead screw 22 is fixedly connected to the circular holes via bearings, and a shaft seal is provided at the gap between the lead screw 22 and the circular holes. The circular holes provide a through channel for the lead screw 22 to ensure smooth rotation; the shaft seal between the circular holes and the lead screw 22 seals the gap between them, preventing leakage of the cooling medium between the outer shell 11 and the inner liner 13, and maintaining a stable internal environment in the inner liner 13. Both ends of the drive shaft 25 are fixedly connected to the back of the inner liner 13 via bearing seats. The bearing seats limit the axial and radial displacement of the drive shaft 25, ensuring that the drive shaft 25 remains stable during rotation.

[0031] A mounting base is fixedly connected to the surface of the motor 28. The bottom of the mounting base is fixedly connected to the top of the inner liner 13. The mounting base fixes the motor 28 to the top of the inner liner 13, which can reduce the vibration generated by the motor 28 during operation from being transmitted to the inner liner 13 or the outer shell 11, reduce the impact of vibration on the plate, enhance the installation stability of the motor 28, and extend the service life of the motor 28.

[0032] The working principle of this utility model is as follows: First, the magnesium alloy plate is placed on top of the support roller 15 inside the inner liner 13 through the sealing door 18 on the surface of the inner liner 13, and the sealing door 18 is closed to ensure the airtightness of the inner liner 13. Subsequently, cooling medium is injected into the space between the outer shell 11 and the inner liner 13 through the one-way electromagnetic water inlet valve 16, and the discharge of cooling medium is controlled by the one-way electromagnetic drain valve 17 to achieve cooling medium circulation, regulate the temperature around the inner liner 13, and avoid a high-temperature environment. At the same time, the vacuum valve 14 at the top of the inner liner 13 works in conjunction with an external vacuum pump to create a vacuum inside the inner liner 13, isolating oxygen to prevent oxidation of the board. When the board needs to be moved, the motor 28 is started, which drives the worm gear 27 to rotate. The worm gear 27 drives the worm wheel 26 to rotate, and the worm wheel 26 drives the transmission shaft 25 to rotate synchronously. The active bevel gears 24 at both ends of the transmission shaft 25 rotate accordingly. The active bevel gears 24 drive the driven bevel gears 23 to rotate, and the driven bevel gears 23 drive the lead screw 22 to rotate. Since the lead screw 22 is threadedly connected to the push plate 21, when the lead screw 22 rotates, it pushes the push plate 21 to move smoothly along the groove. The push plate 21 contacts the back of the board and pushes the board to move on the support roller 15, realizing the automated pushing of the board.
