Description

Technical Field

[0001] This invention belongs to the field of magnesium alloy smelting and casting technology, and in particular relates to a magnesium alloy smelting and casting equipment and its smelting process. Background Technology

[0002] Magnesium is an alkaline earth metal in Group IIA of the periodic table. Its element symbol is Mg, and its relative atomic mass is 24.305. It is a silvery-white, ductile metal with a relative density of 1.74 g / cm³, a melting point of 648.8℃, and a boiling point of 1107℃. It is considered a reactive metal. It is relatively stable in dry air. When heated and reacting with water, and with most nonmetals such as halogens, nitrogen, and sulfur, it dissolves in acids and releases hydrogen gas. It has strong reducing properties. Cast magnesium alloys are magnesium-based alloys with added alloying elements, suitable for manufacturing parts using casting methods. According to the forming process, magnesium alloys can be divided into cast magnesium alloys and wrought magnesium alloys, which differ significantly in composition, microstructure, and properties. Cast magnesium alloys are mainly used for automotive parts, machine housings, and electrical components; wrought magnesium alloys are mainly used for thin plates, extrusions, and forgings.

[0003] Existing magnesium alloy smelting and casting equipment has the following shortcomings in use: 1. In order to accelerate the rapid melting of raw materials, it is generally necessary to crush the raw materials and then put them into the melting furnace. However, during the feeding process, due to the fixed feeding angle, the raw materials are piled up in the melting furnace, resulting in insufficient heating of the raw materials, which affects the melting speed. 2. After molten magnesium alloy is melted, it is introduced into the casting equipment through a conduit. However, after the introduction is complete, residual molten magnesium alloy remains in the conduit. Upon cooling, this residue easily adheres to the conduit, causing blockages and affecting subsequent normal use. To address this issue, we provide a magnesium alloy melting and casting equipment and its melting process to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a magnesium alloy smelting and casting equipment and its smelting process. By synchronously rotating two guide cones in opposite directions, the pulverized raw materials are dispersed and fed into the smelting furnace, preventing the pulverized materials from piling up and causing insufficient heating, which would affect the smelting speed. Furthermore, the included liquid guiding component ensures that any residual molten magnesium alloy in the liquid guiding pipe is promptly cleaned, preventing blockages caused by molten magnesium alloy residue, thus affecting subsequent normal operation. This invention solves the problems of existing smelting and casting equipment where a fixed raw material feeding angle causes the raw materials to pile up in the smelting furnace, resulting in insufficient heating and affecting the smelting speed, and where residual molten magnesium alloy in the guiding pipe easily adheres to the pipe after cooling, causing blockages and affecting subsequent normal operation.

[0014] This invention also includes a smelting process for a magnesium alloy smelting and casting apparatus, comprising the following steps: S01: First, the raw material is put into the second chamber. The raw material is crushed by the rotation of two crushing rollers. The crushed raw material enters the first chamber. S02: Then, the two guide cones rotate synchronously in opposite directions to disperse the crushed raw materials, so that the dispersed crushed raw materials can be put into the smelting furnace. S03: Next, the raw materials are melted in a melting furnace, and then the melted raw materials are injected into the casting assembly through the liquid guiding component to realize the casting production of magnesium alloy.

[0015] The present invention has the following beneficial effects: 1. The present invention uses two guide cones to rotate synchronously in opposite directions, so that the crushed raw materials are dispersed and put into the melting furnace, avoiding the crushed raw materials from piling up in the melting furnace, which would result in insufficient heating and affect the melting speed. In addition, the liquid guiding component is set up so that the molten magnesium alloy remaining in the liquid guiding pipe can be cleaned in time, avoiding the blockage of the liquid guiding pipe caused by the molten magnesium alloy residue, which would affect the subsequent normal use.

[0016] 2. This invention controls the insertion rod to rotate counterclockwise, causing the insertion rod to engage with the two first sliding grooves via two sliders. This further drives the sleeve to rotate counterclockwise, which in turn drives the rotating plate to rotate counterclockwise, and consequently the sealing plate to rotate counterclockwise. The sealing plate rotates away from the smelting furnace, opening the top of the smelting furnace and facilitating the smooth entry of the pulverized raw materials into the furnace. After the pulverized raw materials are fully introduced into the furnace, the insertion rod is controlled to rotate in the opposite direction, causing the sealing plate to rotate clockwise. When the sealing plate contacts the arc-shaped baffle, it completely seals the top of the smelting furnace, effectively preventing heat loss and facilitating subsequent venting of gases from the furnace.

[0017] 3. This invention controls a motor to drive a bidirectional worm gear to rotate, which in turn drives two meshing worm wheels to rotate. These worm wheels, in turn, drive two crushing rollers to rotate. The raw material is then fed into the second chamber, where the two crushing rollers crush the material, making it easier to melt finer materials. The rotation of one of the rollers drives a second sprocket to rotate, which in turn drives a first sprocket to rotate via a chain, providing power for the first sprocket to rotate.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1-16The present invention provides the following technical solution: a magnesium alloy smelting and casting equipment, comprising a smelting component 1, a distribution component 2 disposed on the smelting component 1, a crushing component 3 disposed on the smelting component 1 above the distribution component 2, a liquid guiding component 4 disposed on one side of the smelting component 1, and a casting component 5 disposed on the distribution component 2 connected to the liquid guiding component 4; the smelting component 1 is used for smelting magnesium alloy; the distribution component 2 is used for dispersing and feeding raw materials; the crushing component 3 is used for crushing raw materials; the liquid guiding component 4 is used for guiding molten magnesium alloy; and the casting component 5 is used for casting molten magnesium alloy.

[0023] The smelting assembly 1 includes a Z-shaped base 101, a smelting furnace 102 fixedly connected to the top of the Z-shaped base 101, a first vertical plate 103 symmetrically fixedly connected to the top of the Z-shaped base 101, and a control box 104 fixedly connected to the top of the Z-shaped base 101. A first mounting plate 105 is fixedly connected to the outer wall of the smelting furnace 102, a sleeve 106 is rotatably connected to the top of the first mounting plate 105, a rotating plate 107 is fixedly fitted onto the outer wall of the sleeve 106, a sealing plate 108 adapted to the top of the smelting furnace 102 is fixedly connected to one side of the rotating plate 107, an arc-shaped baffle 109 adapted to the sealing plate 108 is fixedly connected to the top of the smelting furnace 102, a first sliding groove 110 symmetrically opened on the inner wall of the sleeve 106, an insert rod 111 slidably connected to the inner wall of the sleeve 106, and an insert rod 111 symmetrically fixedly connected to the outer wall of the insert rod 111. The slider 121 is slidably connected to the two first sliding grooves 110. The outer wall of the insertion rod 111 is evenly provided with several slots 112 distributed in a circumferential array. The outer wall of the insertion rod 111 is provided with a first annular groove 113. The inner wall of the first annular groove 113 is rotatably connected with a collar 114. The top of the rotating plate 107 is fixedly connected with an electric push rod 115. The output end of the electric push rod 115 is fixedly connected with a connecting plate 116. The connecting plate 116 is fixedly connected with the collar 114. The inner wall of the smelting furnace 102 is rotatably connected with a first rotating shaft 117 extending to its outside. The end of the first rotating shaft 117 is fixedly connected with a first pulley 118. The outer wall of the first rotating shaft 117 is fixedly and symmetrically connected with several mixing rods 119 located inside the smelting furnace 102. The outer wall of the smelting furnace 102 is connected with a first conduit 120.

[0024] The operation process of this embodiment is as follows: By controlling the insertion rod 111 to rotate counterclockwise, the insertion rod 111 engages with the two first sliding grooves 110 through the two sliders 121, causing the insertion rod 111 to further drive the sleeve 106 to rotate counterclockwise. The sleeve 106 then drives the rotating plate 107 to rotate counterclockwise, which in turn drives the sealing plate 108 to rotate counterclockwise. This causes the sealing plate 108 to rotate away from the smelting furnace 102, opening the top of the smelting furnace 102 and facilitating the smooth entry of the pulverized raw materials into the furnace. Inside the smelting furnace 102, after the crushed raw materials are completely fed into the smelting furnace 102, the insert rod 111 is controlled to rotate in the opposite direction, thereby causing the sealing plate 108 to rotate clockwise. When the sealing plate 108 rotates to contact the arc-shaped baffle 109, the sealing plate 108 just covers the top of the smelting furnace 102, so that the inside of the smelting furnace 102 is in a closed state, thereby effectively preventing the heat loss inside the smelting furnace 102 and facilitating the subsequent venting of the gas inside the smelting furnace 102. In addition, by controlling the rotation of the first pulley 118, the first rotating shaft 117 drives several mixing rods 119 to rotate, so that the mixing rods 119 continuously stir the raw materials inside the melting furnace 102. On the one hand, this can accelerate the full heating of the raw materials and increase the melting speed. On the other hand, the stirring of the mixing rods 119 can quickly remove the gas mixed in the molten magnesium alloy liquid, so as to avoid the formation of cracks in the magnesium alloy after casting in the subsequent casting process, which would affect the production quality.

[0025] Example 2, please refer to Figure 1-16 This second embodiment improves upon the first embodiment as follows: the sharing component 2 includes a first housing 201, with first ear plates 202 symmetrically fixedly connected to the outer wall of the first housing 201. The two first ear plates 202 are fixedly connected to the two first upright plates 103 one-to-one. The inner wall of the first housing 201 has two second annular grooves 203, and the outer wall of the first housing 201 has an arc-shaped notch 204 communicating with the second annular grooves 203.

A third rotating shaft 216 is rotatably connected through an adjacent side of the U-shaped plate 212.

A first spring 223 is fixedly connected between the first baffle 222 and the sleeve 220 and is sleeved on the locking rod 221.

[0027] The operation process of this embodiment is as follows: by controlling the first sprocket 219 to rotate, the first sprocket 219 drives the third rotating shaft 216 to rotate, which in turn drives the second pulley 218 to rotate, so that the second pulley 218 drives the first pulley 118 to rotate through the belt, thus providing power for the rotation of the first pulley 118. The rotation of the third rotating shaft 216 further drives the second bevel gear 217 to rotate, which in turn drives the two second bevel gears 214 meshing with it to rotate. The two second bevel gears 214 rotate in opposite directions, which in turn drives the two third rotating shafts 216 and the spur gear 215 to rotate. The spur gear 215 then drives the gear ring 206 meshing with it to rotate, which in turn drives the guide cone 208 to rotate through the annular plate 205 and the connecting rod 207. The guide cone 208 rotates in opposite directions, allowing the crushed raw material to be dispersed and fed into the melting furnace 102 through the opposite rotation of the two guide cones 208. This prevents the crushed raw material from piling up in the melting furnace 102, which would result in insufficient heating and affect the melting speed.

An upper mold 504 adapted to the lower mold 501 is fixedly connected to the output end of the hydraulic cylinder 503. A hose 505 is provided to connect the upper mold 504 and the liquid guide pipe. A PLC controller is provided inside the control box 104. The PLC controller is electrically connected to the electric push rod 115, the motor 307, the arc-shaped electromagnet plate 404, the hydraulic cylinder 503, the first solenoid valve 402, the second solenoid valve, and the third solenoid valve.

[0033] The operation process of this embodiment is as follows: After the raw materials inside the melting furnace 102 are fully melted, the first solenoid valve 402 and the second solenoid valve on the liquid guide pipe 401 are opened, so that the molten magnesium alloy is introduced into the casting component 5 through the liquid guide pipe 401. Then, the magnesium alloy is cast in the casting component 5. After casting is completed, the upper mold 504 is moved upward by controlling the hydraulic cylinder 503, so that the upper mold 504 is separated from the lower mold 501. Then, the magnesium alloy in the lower mold 501 is demolded, thus completing the casting production of magnesium alloy. Before the molten magnesium alloy is introduced into the casting assembly 5, the vacuum pump 410 is started to draw air from the melting furnace 102 and store it in the air bag 412. After the molten magnesium alloy is introduced into the casting assembly 5, the first solenoid valve 402 and the second solenoid valve on the liquid guide pipe 401 are closed, and then the third solenoid valve on the second conduit 415 is opened to inject gas from the air bag 412 into the liquid guide pipe 401. Because a one-way valve is installed on the flow pipe 414, the gas cannot pass through the flow pipe 414 from the right side to the right side of the piston plate 413, which increases the pressure on the right side of the piston plate 413. This causes the piston plate 413 to move to the left, scraping the molten magnesium alloy remaining in the liquid guide pipe 401 to the left. When the piston plate 413 moves to the leftmost position, the molten magnesium alloy on the left side of the piston plate 413 will enter the right side of the piston plate 413 along the flow pipe 414. During this process, the arc-shaped electromagnet plate 404 is energized, causing it to attract the piston plate 413. This, in turn, moves the piston plate 413 and the extension plate 405 to the left, causing the extension plate 405 to compress the second spring 409. Then, the second solenoid valve and the third solenoid valve on the exhaust pipe 416 are opened, while the third solenoid valve on the second conduit 415 is closed. At this time, the gas on the right side of the piston plate 413 is discharged through the exhaust pipe 416, reducing the gas pressure on the right side of the piston plate 413. Simultaneously, under the elastic force of the second spring 409, the extension plate 405 and the arc-shaped electromagnet plate 404 are moved to the right, further moving the piston plate 413 to the right. This causes the piston plate 413 to move the molten magnesium alloy remaining inside the liquid guide pipe 401 to the right, pushing it into the casting assembly 5. This prevents the molten magnesium alloy remaining inside the liquid guide pipe 401 from sticking to its inner wall after cooling, causing blockage of the liquid guide pipe 401 and affecting subsequent use.
