Technical Field
[0001] This utility model relates to the field of magnesium alloy sheet production technology, and in particular to a lubrication device used in the rolling process of magnesium alloy sheets. Background Technology
[0002] Magnesium alloys possess material properties such as low density, high specific strength and specific stiffness, and good electrical and thermal conductivity. However, in practice, magnesium alloy sheets have disadvantages such as easy corrosion, easy oxidation, and easy combustion during the rolling process. Magnesium alloys are extremely prone to combustion and explosion during high-temperature rolling. The dripping, falling, and scattering of lubricating oil used in the rolling process are also important factors that cause fires. When magnesium sheets are rolled into shape by rolling rolls, in order to avoid bending and sticking of the magnesium sheet shape and to ensure a smooth surface, a layer of lubricating oil is usually sprayed on the surface of the rolls to make the magnesium sheet easier to roll into shape.
[0003] In existing technologies, lubricating oil is mostly applied to magnesium alloy plates manually using a spray gun. The quality of lubrication can be affected by factors such as the distance between the gun and the roll surface being too high or too low, or the speed of manual movement during oil spraying.
[0004] To address the aforementioned issues, we propose a lubrication device for use in the rolling process of magnesium alloy sheets. Utility Model Content

Detailed Implementation
[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0018] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a top view of the entire utility model. Figure 3 This is a utility model Figure 2 A cross-sectional view of the AA line structure.
[0019] This utility model provides a lubrication device for use in the rolling process of magnesium alloy sheets, including a worktable 101 and a lubrication coating assembly. The lubrication coating assembly includes a support plate 102, a top plate 103, a forward roller 106, a reverse roller 107, a mounting frame 112, a push column 113, a disassembly plate 114, a graphite strip 115, a conveyor table 108, an extension plate 109, a push button 110, a retraction button 111, a forward motor 104, and a reverse motor 105. This solution solves the problem that in the prior art, most lubricants are manually applied to the magnesium alloy sheet using a spray gun, which is problematic due to issues such as the gun being held too high or too low from the roller surface, or manual movement during spraying. The speed of rotation and other factors can affect the quality of roller surface lubrication. Understandably, the aforementioned solution allows workers to press the push button 110 after starting the forward motor 104 and the reverse motor 105 during the production of magnesium alloy sheets. The push column 113 will then slowly push the disassembly plate 114 and the graphite strip 115 toward the forward roller 106 and the reverse roller 107. As a result, the graphite strip 115 will coat the surfaces of the forward roller 106 and the reverse roller 107 with a layer of graphite powder. During the friction process, the layered structure of graphite causes some graphite particles to transfer to the friction surface, forming a stable solid lubricating film. This lubricating film can isolate direct contact between friction surfaces, thereby reducing friction and wear and achieving a self-lubricating effect. Air and water molecules on the graphite surface will form a lubricating film, which can further reduce friction and wear. In addition, the tiny particles in graphite can fill the irregular parts of the surface, thereby reducing friction. Graphite has good chemical stability and can maintain its lubricating performance under harsh environments such as high temperature and high pressure. Graphite is used as a lubricant or applied to the parts that need lubrication by spraying. When it comes into contact with the metal surface, it can not only form a strong lubricating film, but also improve the wetting performance of the metal surface to other lubricants, thereby maintaining a long-term lubrication effect. This will effectively solve the problem that in the existing technology, most of the lubricating oil is applied to magnesium alloy plates manually using a spray gun. The quality of roller surface lubrication is affected by factors such as the distance between the gun and the roll surface being too high or too low, or the speed of manual movement during oil spraying.
[0020] In this specific embodiment, the support plate 102 is detachably connected to the worktable 101 and is located above the worktable 101. The top plate 103 is fixedly connected to the support plate 102 and is located above the support plate 102. The forward roller 106 is rotatably connected to the support plate 102 and is located on one side of the support plate 102. The reverse roller 107 is rotatably connected to the support plate 102 and is located on one side of the support plate 102. The reverse roller 107 is located below the forward roller 106. The worktable 101 is the main place for lubrication, while the forward roller 106 and the reverse roller 107 are the main auxiliary components for brushing graphite powder onto the surface of the magnesium alloy sheet.
[0021] The mounting frame 112 is detachably connected to the support plate 102 and is located on one side of the support plate 102. The mounting frame 112 is also located on one side of the forward roller 106 and the reverse roller 107. The push column 113 is detachably connected to the mounting frame 112 and is located on the side of the mounting frame 112 close to the forward roller 106 and the reverse roller 107. The disassembly plate 114 is detachably connected to the push column 113 and is located on the side of the push column 113 away from the mounting frame 112. The graphite strip 115 is detachably connected to the disassembly plate 114 and is located on the side of the disassembly plate 114 away from the push column 113. The mounting frame 112 is the location for mounting the push column 113, while the disassembly plate 114 is a component that facilitates the installation and removal of the graphite strip 115 by workers. The graphite strip 115 is a functional component for applying graphite to the surfaces of the forward roller 106 and the reverse roller 107.
[0022] Secondly, the conveyor 108 is fixedly connected to the workbench 101 and is located above the workbench 101. The conveyor 108 is disposed on one side of the support plate 102 and is also perpendicular to the support plate 102. The conveyor 108 will be a functional component for conveying magnesium alloy plates.
[0023] Meanwhile, the extension plate 109 is fixedly connected to the workbench 101 and located on one side of the workbench 101. The push button 110 is fixedly connected to the extension plate 109 and located above the extension plate 109. The retraction button 111 is fixedly connected to the extension plate 109 and located above the extension plate 109. The retraction button 111 is located on one side of the push button 110. The push button 110 and the retraction button 111 will be auxiliary components to facilitate the operator's control of the push column 113.
[0024] Furthermore, the forward rotation motor 104 is detachably connected to the support plate 102 and is located on the side of the support plate 102 away from the forward rotation roller 106. The output end of the forward rotation motor 104 passes through the support plate 102 and is detachably connected to the forward rotation roller 106, and is located on one side of the forward rotation roller 106. The reverse rotation motor 105 is detachably connected to the support plate 102 and is located on the side of the support plate 102 away from the reverse rotation roller 107. The output end of the reverse rotation motor 105 passes through the support plate 102 and is detachably connected to the reverse rotation roller 107, and is located on one side of the reverse rotation roller 107. The forward rotation motor 104 and the reverse rotation motor 105 are functional components that provide the necessary power to the forward rotation roller 106 and the reverse rotation roller 107.
[0025] When using this invention to produce magnesium alloy sheets, the operator will press the push button 110 after the forward motor 104 and the reverse motor 105 are started. The push column 113 will slowly push the disassembly plate 114 and the graphite strip 115 toward the forward roller 106 and the reverse roller 107. As a result, the graphite strip 115 will coat the surface of the forward roller 106 and the reverse roller 107 with a layer of graphite powder. During the friction process, the layered structure of the graphite causes some graphite particles to transfer to the friction surface, forming a stable solid lubricating film. This lubricating film can isolate direct contact between friction surfaces, thereby reducing friction and wear and achieving a self-lubricating effect. Air and water molecules on the graphite surface will form a lubricating film, which can further reduce friction and wear. In addition, the tiny particles in graphite can fill the irregular parts of the surface, thereby reducing friction. Graphite has good chemical stability and can maintain its lubricating performance under harsh environments such as high temperature and high pressure. Graphite is used as a lubricant or applied to the parts that need lubrication by spraying. When it comes into contact with the metal surface, it can not only form a strong lubricating film, but also improve the wetting performance of the metal surface to other lubricants, thereby maintaining a long-term lubrication effect. This will effectively solve the problem that in the existing technology, most of the lubricating oil is applied to magnesium alloy plates manually using a spray gun. The quality of roller surface lubrication is affected by factors such as the distance between the gun and the roll surface being too high or too low, or the speed of manual movement during oil spraying.
