Description

Technical Field

[0001] The utility model relates to the technical field of rust prevention equipment for magnesium alloy processing, and specifically relates to a rust removal device for rust prevention in magnesium alloy processing. Background Technique

[0002] Magnesium alloy has a small density, about 2 / 3 of aluminum alloy and 1 / 4 of steel, which can effectively reduce the weight of components and has important application value in the fields of aerospace, automobiles, etc. Magnesium alloy has high specific strength and specific stiffness, and can maintain good mechanical properties while reducing weight, meeting the use requirements of structural parts. However, the chemical properties of magnesium alloy are active, and rusting of magnesium alloy parts is likely to occur. The magnesium alloy parts can be coated with a layer of oil film on the surface for rust prevention treatment. The lubricating oil forms a continuous oil film on the surface of the magnesium alloy, isolating the magnesium alloy from corrosive media such as air and moisture, thereby preventing oxygen, water, etc. from reacting chemically with the magnesium alloy and playing a role in rust prevention.

[0003] In the market, general rust removal devices for magnesium alloy use oil bath or drip lubrication during use. The amount of lubricating oil used is relatively large during use, bringing a certain economic burden to enterprises. At the same time, during the spraying process, the lubricating oil also splashes everywhere, and it requires personnel to clean the splashed oil stains for a long time, bringing troubles to users. Therefore, we propose a rust removal device for rust prevention in magnesium alloy processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rust removal device for rust prevention in magnesium alloy processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rust removal device for rust prevention in magnesium alloy processing, including a base, an arc-shaped limiting plate, and a lubricating oil conveying pipeline. Brackets are fixed around the upper end of the base, and a turntable for placing magnesium alloy processing parts is erected in the middle of the upper end of the base. In the middle of the inner walls of the brackets around, a cross frame is fixed, and the cross frame is in an "丄" shape and is welded and fixed to the end brackets. Arc-shaped limiting plates are fixed on both sides of the cross frame, and the lubricating oil conveying pipeline is installed on the brackets and the cross frame through clamps.

[0006] Preferably, vertical rods are fixed on both sides of the lower end of the brackets, and the bottom of the vertical rods is fixedly connected to the base.

[0007] Preferably, side baffles for shielding and protection are distributed at the rear end of the turntable, and the side baffles are fixed on the vertical rods.

[0008] Preferably, the inner wall of the arc-shaped limiting plate has a waist-tightening hole in the middle, and a connecting rod is slidably connected inside the waist-tightening hole. A baffle is fixed at the bottom of the lower end of the connecting rod, and an electric push rod is movably connected to the top of the upper end of the connecting rod. A movable arm is fixed at the end of the electric push rod away from the connecting rod, and the movable arm is movably connected to the cross frame.

[0009] Preferably, the electric push rod forms a pulling structure with the baffle through a connecting rod.

[0010] Preferably, one side of the lubricating oil delivery pipeline is connected to several branch pipelines, and the ends of the several branch pipelines are all connected to control valves. The end of the control valve away from the branch pipeline is connected to an atomizing nozzle, and the outer wall of the atomizing nozzle is equipped with a mounting bracket. The delivery end of the lubricating oil delivery pipeline is connected to an air compressor.

[0011] Preferably, the top of the mounting bracket is fixed with fastening bolts, and the fastening bolts are bolted to the crossbar.

[0012] Preferably, the control valve, mounting bracket, fastening bolts, and atomizing nozzles constitute a lubricating oil spraying structure, and several lubricating oil spraying structures are mounted on the crossbeam. One lubricating oil spraying structure is also mounted on one side of the bracket, and the atomizing nozzles of the lubricating oil spraying structures mounted on the bracket are distributed at an inclined angle.

[0013] Preferably, a transmission disk is mounted on the lower end of the turntable, and a transmission shaft is keyed to the inner wall of the lower end of the transmission disk. The output end of the transmission shaft is keyed to a servo motor, which is a power source.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the rust removal device for magnesium alloy processing is used, the lubricating oil delivery pipeline uses compressed air or other power sources to spray the lubricating oil through the atomizing nozzle, which can evenly distribute the lubricating oil on the lubrication surface, avoiding local insufficient or excessive lubrication, thereby improving the coverage. At the same time, since the atomized lubricating oil can be delivered more accurately to the parts that need lubrication, it will not cause a large amount of lubricating oil waste. Compared with traditional lubrication methods, such as oil bath or drip lubrication, it can significantly reduce the amount of lubricating oil used. The magnesium alloy processed parts can achieve a good rust prevention effect by being coated with lubricating oil all over, thus extending the service life of the magnesium alloy processed parts.

[0015] This baffle serves as a preliminary shielding and protection component for magnesium alloy workpieces, precisely shielding the atomizing nozzles with an inclined angle. The structure is simple to operate, convenient and practical, and can be adjusted according to the different inclination angles of the atomizing nozzles, thereby reducing the splashing of lubricating oil when the magnesium alloy workpieces are sprayed with lubricating oil.

[0016] The side baffle serves as a shielding component, providing some impact resistance and lubrication buffer. The side baffle is installed on the bracket by welding, a method that results in high connection strength and structural stability. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5, the present utility model provides a technical solution: a rust removal device for anti-rust in magnesium alloy processing, including a base 1, an arc-shaped limiting plate 5 and a lubricating oil conveying pipeline 6. Brackets 2 are fixed around the upper end of the base 1, and a turntable 3 for placing magnesium alloy workpieces is installed in the middle of the upper end of the base 1. A cross frame 22 is fixed in the middle of the inner walls of the surrounding brackets 2, and the cross frame 22 is in an "丄" shape and is welded and fixed to the end brackets 2. Arc-shaped limiting plates 5 are fixed on both sides of the cross frame 22. The lubricating oil conveying pipeline 6 is installed on the brackets 2 and the cross frame 22 through clamps, and the conveying end of the lubricating oil conveying pipeline 6 is connected to an air compressor. Vertical rods 21 are fixed on both sides of the lower end of the brackets 2, and the bottom of the vertical rods 21 is fixedly connected to the base 1. Side baffles 4 for shielding and protection are distributed at the rear end of the turntable 3, and the side baffles 4 are fixed on the vertical rods 21. The side baffles 4 serve as shielding components, acting as certain impact-resistant and lubricating oil buffering components. The side baffles 4 are integrally installed on the brackets 2 in a welded form. This connection method has high connection strength and stable structure. At the same time, the side baffles 4 and the turntable 3 are connected in a split manner. When the turntable 3 rotates, the side baffles 4 do not participate in the rotation, meeting the requirement that the side baffles 4 can continuously shield and protect the splashing side baffles 4 for a long time.

[0025] A waist-tightening hole 51 is opened in the middle of the inner wall of the arc-shaped limiting plate 5, and a connecting rod 54 is slidably connected inside the waist-tightening hole 51. A baffle 55 is fixed to the bottom of the lower end of the connecting rod 54. The upper end of the connecting rod 54 is movably connected to an electric push rod 52, and an activity arm 53 is fixed to the end of the electric push rod 52 away from the connecting rod 54. The activity arm 53 is movably connected to the cross frame 22. The electric push rod 52 and the baffle 55 form a pulling structure through the connecting rod 54. The baffle 55 serves as a preliminary shielding and protection component for the magnesium alloy workpiece, precisely shielding the atomizing nozzles 65 distributed at an inclination angle. At the same time, the distribution angle and position of the baffle 55 are adjustable. When the position of the baffle 55 needs to be changed, the electric push rod 52 can be pushed out to drive its connecting rod 54 to be adjusted synchronously along the waist-tightening hole 51 inside the arc-shaped limiting plate 5, and adjusted along the arc-shaped waist-tightening hole 51, thereby changing the placement position and angle of the baffle 55. This structure is simple to operate, convenient and practical, and can meet the requirement that the baffle 55 can be adjusted accordingly according to the different inclination angles of the atomizing nozzles 65, thereby reducing the situation of lubricating oil splashing when the magnesium alloy workpiece is sprayed with lubricating oil.

[0026] A lubricating oil delivery pipeline 6 has several branch pipelines 61 connected to one side, and each branch pipeline 61 has a control valve 62 connected to its end. The end of the control valve 62 furthest from the branch pipeline 61 is connected to an atomizing nozzle 65. A mounting bracket 63 is mounted on the outer wall of the atomizing nozzle 65, and a fastening bolt 64 is fixed to the top of the mounting bracket 63. The fastening bolt 64 is bolted to the crossbeam 22. The control valve 62, mounting bracket 63, fastening bolt 64, and atomizing nozzle 65 constitute a lubricating oil spraying structure. Several lubricating oil spraying structures are mounted on the crossbeam 22, and a lubricating oil spraying structure is also mounted on one side of the support 2. The atomizing nozzles 65 of the lubricating oil spraying structure mounted on the support 2 are distributed at an inclined angle. This lubricating oil delivery pipeline 6 uses compressed air or other power sources to spray lubricating oil through the atomizing nozzles 65, which can evenly distribute the lubricating oil on the lubrication surface and avoid localized damage. This system addresses both insufficient and excessive lubrication, thus improving coverage. The atomized lubricating oil is delivered more precisely to the areas requiring lubrication without significant waste. Compared to traditional lubrication methods like oil baths or drip lubrication, it significantly reduces oil consumption. Applying lubricating oil to the entire surface of magnesium alloy workpieces provides excellent rust prevention, extending their service life. The system features a wide-area spray design, with several spray structures mounted on the crossbeam 22 to meet the spraying needs of magnesium alloy workpieces of various sizes. Additionally, an angled spray structure is installed on the support 2, allowing for spraying of hard-to-reach areas on the sides of the workpiece, improving spraying efficiency and providing convenience for the user.

[0027] A transmission disk 31 is mounted on the lower end of the turntable 3, and a transmission shaft 32 is keyed to the inner wall of the lower end of the transmission disk 31. A servo motor 33, a power source, is keyed to the output end of the transmission shaft 32. The servo motor 33 serves as the power source for the rotation of the turntable 3. When the user needs to perform all-round spraying operations on the magnesium alloy workpiece, the user can turn on the servo motor 33, and the transmission shaft 32 and transmission disk 31 will rotate synchronously. The turntable 3 will rotate accordingly, and the magnesium alloy workpiece above it will rotate, which will facilitate the subsequent lubricating oil spraying structure to perform all-round spraying operations on the magnesium alloy workpiece.

[0028] Working Principle: For this type of rust removal device used for rust prevention in magnesium alloy processing, the magnesium alloy workpiece is first placed on the turntable 3. The user then turns on the servo motor 33, and the drive shaft 32 and drive disk 31 rotate synchronously. The turntable 3 rotates accordingly, and the magnesium alloy workpiece on it rotates. Then, the lubricating oil delivery pipe 6 uses compressed air or other power sources to spray lubricating oil through the atomizing nozzle 65. The lubricating oil spraying structure with an inclined distribution is installed on the bracket 2. When the baffle 55 cannot block the sprayed lubricating oil as much as possible, and the position of the baffle 55 needs to be changed, it can be pushed out by the electric push rod 52, which drives its connecting rod 54 to be adjusted synchronously along the waist tightening hole 51 in the arc-shaped limiting plate 5. Adjusting along the waist tightening hole 51, the placement position and angle of the baffle 55 are changed. Finally, after the lubricating oil is applied to the magnesium alloy workpiece, the user can remove the magnesium alloy workpiece from the turntable 3. This completes the entire process of using the rust removal device for rust prevention in magnesium alloy processing.
