Description

Technical Field

[0001] This utility model relates to the field of magnesium alloy smelting technology, and in particular to an anti-oxidation protective gas device for magnesium alloy smelting. Background Technology

[0002] The processes for manufacturing magnesium alloy parts can be divided into four main categories: casting metallurgy, rapid solidification / powder metallurgy, spray deposition, and semi-solid forming. In addition to these four methods, there are also parts made from magnesium and magnesium alloy semi-finished products (plates, strips, tubes, bars, profiles, and forgings) produced by various pressure processing plastic forming processes. Whether preparing pressure-processed magnesium alloy ingots or producing magnesium alloy parts, smelting is an extremely critical process because it has a decisive impact on the quality of the melt and, consequently, the performance of the material and castings. The quality of raw materials, fluxes, smelting processes, equipment, and tools all affect the quality of the melt. At the same time, compared with other commonly used metals, magnesium is much more chemically reactive. Its melt is extremely prone to chemical reactions with oxygen, nitrogen, water, etc., and the probability of combustion and explosion is also greater. The corrosion resistance of magnesium and magnesium alloys is very sensitive to impurity elements such as iron, nickel, and copper. Anti-oxidation protective gas devices are required during magnesium alloy smelting.

[0003] However, in practical applications, the inconvenience of connecting and positioning the pipeline can affect the sealing of subsequent connections, leading to pipeline leaks. This affects the ease of use of the device and its subsequent efficiency. Utility Model Content

Mounting plates 16 have oblong holes, and their lower surfaces have anti-slip textures. The mounting plates 16 facilitate positioning of the device during use, thus maintaining its stability. A ring 2 is fixedly installed on the upper surface of the base 1. A screw 17 is inserted into one side of the ring 2. One end of the screw 17 is threaded to the surface of a cylinder 3, and a turntable is fixedly installed at the other end of the screw 17. The turntable has grooves on its surface, and these grooves also have anti-slip textures. The screw 17 allows for positioning between the ring 2 and the cylinder 3 during use, facilitating the installation of the cylinder 3 and maintaining stability. The device features a stable connection. The ring 2 has a threaded hole for the screw 17 to pass through, which is threadedly connected to the screw 17. The cylinder 3 has a threaded hole on its surface, which is threadedly connected to one end of the screw 17. This threaded hole facilitates tightening the screw 17 during use and maintains subsequent installation stability. The cylinder 3 is inserted inside the ring 2. A motor 4 is fixedly mounted on the top of the cylinder 3. A stirring rod 5 is fixedly mounted on the output shaft of the motor 4. The bottom of the stirring rod 5 penetrates the top of the cylinder 3 and extends into the interior of the cylinder 3. An exhaust pipe 6 connects to the top of the cylinder 3. A connecting pipe 7 and an air inlet pipe 8 connect to the surface of the cylinder 3. A rod hole for the stirring rod 5 to pass through is provided at the top of the cylinder 3, and the inner wall of the rod hole is rotatably connected to the surface of the stirring rod 5.

[0018] The motor 4 is installed so that it can drive the stirring rod 5 to rotate during use. The stirring rod 5 can then drive the gas in the cylinder 3 to mix, thereby improving the gas mixing degree of the device and maintaining the ease of use of the device, making it convenient for subsequent use.

[0019] A cavity is formed on the base 1, and a slide plate 9 is slidably connected inside the cavity. Slider blocks 10 are fixedly installed on both sides of the slide plate 9. A slide rod 11 is fixedly installed on the top of each slide rod 10, with the top of the slide rod 11 penetrating the base 1 and extending to the outside of the base 1. A threaded post 12 is inserted into the slide plate 9, with one end of the threaded post 12 penetrating the base 1 and extending to the outside of the base 1. The tops of the two slide rods 11 are fixedly connected by a sliding plate 13. A locking block 14 is fixedly installed on the top of the sliding plate 13, and a transmission tube 15 is inserted into the locking block 14. One end of the transmission tube 15 contacts one end of the connecting tube 7. A threaded hole is formed on the slide plate 9 for the threaded post 12 to pass through, and the threaded hole is threadedly connected to the threaded post 12. A round hole is formed on one side of the base 1 for the threaded post 12 to pass through, and one end of the threaded post 12 is fitted with a... The threaded post 12 is rotatably connected to a sleeve, one end of which is fixedly connected to one side of the inner wall of the cavity.

[0020] The threaded post 12 can be rotated during use, which in turn moves the slide plate 9 on the threaded post 12. This, in turn, moves the slide rod 11 on the slider 10. Simultaneously, the moving plate 13 and the locking block 14 on the slide rod 11 move, which in turn moves the transmission pipe 15 on the locking block 14. This increases the sealing between the transmission pipe 15 and the connecting pipe 7, thus preventing pipe leakage and improving the ease of use of the device. It also reduces the impact on the subsequent efficiency of the device.

[0021] Working principle: The threaded column 12 can be rotated during use, which in turn moves the slide plate 9 on the threaded column 12, thereby moving the slide rod 11 on the slider 10. At the same time, the moving plate 13 and the locking block 14 on the slide rod 11 move, which in turn moves the transmission pipe 15 on the locking block 14. This increases the sealing between the transmission pipe 15 and the connecting pipe 7, thus preventing pipeline leakage and improving the ease of use of the device. It also reduces the impact on the subsequent use efficiency of the device. The motor 4 can drive the stirring rod 5 to rotate during use, which in turn drives the gas in the cylinder 3 to mix, thereby improving the gas mixing degree of the device and maintaining the ease of use of the device for subsequent use.
