Description

Technical Field

[0001] This invention relates to the field of aluminum ingot forming, and more particularly to an aluminum ingot forming apparatus. Background Technology

[0002] Continuous casting machines are commonly used production equipment in metal casting, especially in aluminum ingot manufacturing. Continuous casting machines should have the ability to continuously produce profiles of the same specifications. Therefore, continuous casting machines are equipped with several molds of the same model, as well as corresponding demolding devices. Among these, the most widely used is the hammering component. Before demolding, the hammering component strikes the corresponding mold, creating a gap within the mold to facilitate the profile's release. As mentioned above, the hammering component targets the mold before demolding. Furthermore, current technology, apart from the pre-demolding hammering, does not provide any subsequent processing of the mold after demolding. Therefore, fine particles remaining on the inner surface of the mold can affect the forming quality of the profile during subsequent casting. Summary of the Invention

[0003] The purpose of this invention is to provide an aluminum ingot forming device to solve the technical problem in the prior art that, in addition to the hammering before demolding, there is no subsequent processing of the mold after demolding. Therefore, fine particles remaining on the inner surface of the mold will affect the forming quality of the profile in subsequent re-pouring.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An aluminum ingot forming apparatus includes a frame and toothed rollers, with two toothed rollers arranged opposite to each other within the frame.

[0006] Two chains are wound around two toothed rollers at a fixed interval, so that the two toothed rollers move together. Several molds are arrayed within the fixed interval between the two chains, and adjacent molds also maintain a fixed interval.

[0007] The first plate is fixed to the frame and adjacent to the mold located below the toothed roller. A second plate is provided between the first plate and the mold. The second plate has a second rod that is connected to the frame and rotates alternately up and down when the toothed roller rotates and contacts different molds.

[0008] The first rod is located outside the mold. The first rod and the second rod are connected by an adapter plate, which allows the first rod to alternately extend into the mold within the working area of ​​the first rod when the second plate rotates up and down alternately.

[0009] Preferably, a sleeve is provided at the first plate, wherein a first one-way valve is embedded in the end of the sleeve away from the first plate; and

[0010] The second check valve, the second check valve in a ring array at the sleeve, and the exhaust direction of the second check valve points to the mold located above the toothed roller;

[0011] The sleeve is equipped with a piston that slides within the sleeve. When the piston slides down or up within the sleeve, air is injected into the sleeve by the first one-way valve or discharged out by the second one-way valve.

[0012] Preferably, a connecting rod is provided between the second plate and the piston, with its two ends rotatably connected to the second plate and the piston, respectively, so that when the second plate rotates up or down, the piston slides up or down inside the sleeve.

[0013] Preferably, a plurality of bristles are arranged around the first rod to rub against the inner wall of the mold when the first rod alternately extends into the mold located in the working area of ​​the first rod.

[0014] Preferably, the frame includes a main frame and roller frames disposed at both ends of the main frame, wherein the roller frames are used to install toothed rollers, and the area of ​​the combination of the main frame and the roller frames is the active area of ​​the chain.

[0015] Preferably, the toothed roller includes a roller located within a roller frame and gears mounted at both ends of the roller, wherein the gears cooperate with a chain drive to link the rollers located within the two roller frames.

[0016] Preferably, a roller shaft is inserted along the axis of the roller and the gear, wherein the roller shaft passes through the roller frame, and the toothed roller is suspended in the corresponding roller frame.

[0017] Preferably, mold brackets are installed at both ends of the mold, wherein the mold brackets are fastened into the openings of the chains, so that the mold is suspended between the two chains.

[0018] Preferably, the opening of the mold is always facing away from the toothed roller.

[0019] The beneficial effects of this invention are:

[0020] In this invention, during the contact between the second plate and another mold, the second plate slides down from the first contact mold to a fixed distance between the molds, and then climbs up to another mold. The above process is actually a reciprocating up-and-down rotation process. During this process, the second plate knocks and vibrates the molds in contact with different molds, thereby promoting the removal of particles inside the mold. In addition, when the second plate rotates up and down alternately, the first rod alternately extends into the mold located in the working area of ​​the first rod to clean the inside of the mold.

[0029] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0030] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0031] Example 1

[0032] This embodiment presents an aluminum ingot forming apparatus; please refer to [link / reference]. Figure 1-2 The main body of the aluminum ingot forming device consists of a main frame 1 with a crossbeam 3 and roller frames 6 installed on both sides of the main frame 1. The crossbeam 3 is arranged horizontally inside the main frame 1, and the two roller frames 6 are respectively equipped with toothed rollers of the same specifications (a guard plate 7 is also installed at the roller frames 6 to cover the toothed rollers and improve the safety factor). It should be noted that the toothed rollers are arranged opposite each other. In addition, a chain 2 is used to connect the two toothed rollers.

[0033] As described above, two toothed rollers are connected using chains 2. Specifically, the two chains 2 are wound around the two toothed rollers at a fixed interval, linking the two toothed rollers together. In addition, a number of molds 8 are arranged within the fixed interval between the two chains 2, and adjacent molds 8 also maintain a fixed interval (e.g., Figure 5 (The fixed spacing shown) It should be noted that the fixed spacing between the two chains 2 is not the same as the fixed spacing between adjacent molds 8.

[0034] Description of toothed rollers: as follows Figure 3 As shown, the toothed roller includes a roller 11 located within a roller frame 6 and gears 10 installed at both ends of the roller 11. The gears 10 are driven by the chain 2, causing the rollers 11 located in the two roller frames 6 to move together. In addition, a roller shaft 5 is inserted along the axis of the roller 11 and the gear 10. The roller shaft 5 passes through the roller frame 6, suspending the toothed roller within the corresponding roller frame 6. Hereinafter, for the convenience of explaining the working mechanism of this embodiment, the combination of gears 10, roller 11 and roller shaft 5 will still be referred to as a toothed roller.

[0035] Please see Figure 4 The aluminum ingot forming device contains a first plate 12. Specifically, the first plate 12 is fixed to the main frame 1 and is adjacent to the mold 8 located below the toothed roller. Please refer to [link to relevant documentation]. Figure 4-7 A second plate 13 is provided between the first plate 12 and the mold 8. The second plate 13 has a second rod 16, which is rotatably connected to the main frame 1. When the toothed roller rotates, the second plate 13 rotates up and down alternately when it contacts different molds 8.

[0036] Please see Figure 4 The aluminum ingot forming device also has a first rod 14, which is located outside the mold 8. The first rod 14 and the second rod 16 are connected by a transition plate 15, which is used to allow the first rod 14 to alternately extend into the mold 8 located in the working area of ​​the first rod 14 when the second plate 13 rotates up and down alternately.

[0037] The core of this embodiment lies in cleaning the inverted mold 8 (the inverted mold 8 is the mold 8 that will be poured with molten aluminum), such as Figure 5 As shown, when the mold 8 is inverted, its opening faces downward. In addition, there is a fixed distance between adjacent molds 8. Therefore, when the toothed roller rotates, the second plate 13 will continuously contact multiple molds 8 that are in motion.

[0038] It should be noted that during the contact between the second plate 13 and one mold 8, the plate will slide from the first contacted mold 8 to a fixed gap between the molds 8, and then climb to another mold 8. The above process is actually a reciprocating up-and-down rotation process. During this process, the second plate 13 taps and vibrates the mold 8 in contact with different molds 8, thereby promoting the removal of particles inside the mold 8. In addition, when the second plate 13 rotates up and down alternately, the first rod 14 alternately extends into the mold 8 located in the working area of ​​the first rod 14. To further explain, several bristles (not shown in the figure) are arranged around the first rod 14. When the first rod 14 alternately extends into the mold 8 located in the working area of ​​the first rod 14, the bristles rub against the inner wall of the mold 8 to clean the inside of the mold 8.

[0039] Example 2

[0040] This embodiment presents an aluminum ingot forming apparatus; please refer to [link / reference]. Figure 1-2 The main body of the aluminum ingot forming device consists of a main frame 1 with a crossbeam 3 and roller frames 6 installed on both sides of the main frame 1. The crossbeam 3 is arranged horizontally inside the main frame 1, and the two roller frames 6 are respectively equipped with toothed rollers of the same specifications (a guard plate 7 is also installed at the roller frames 6 to cover the toothed rollers and improve the safety factor). It should be noted that the toothed rollers are arranged opposite each other. In addition, a chain 2 is used to connect the two toothed rollers.

[0041] As described above, two toothed rollers are connected using chains 2. Specifically, the two chains 2 are wound around the two toothed rollers at a fixed interval, linking the two toothed rollers together. In addition, a number of molds 8 are arranged within the fixed interval between the two chains 2, and adjacent molds 8 also maintain a fixed interval (e.g., Figure 5 (The fixed spacing shown) It should be noted that the fixed spacing between the two chains 2 is not the same as the fixed spacing between adjacent molds 8.

[0042] Description of toothed rollers: as follows Figure 3 As shown, the toothed roller includes a roller 11 located within a roller frame 6 and gears 10 installed at both ends of the roller 11. The gears 10 are driven by the chain 2, causing the rollers 11 located in the two roller frames 6 to move together. In addition, a roller shaft 5 is inserted along the axis of the roller 11 and the gear 10. The roller shaft 5 passes through the roller frame 6, suspending the toothed roller within the corresponding roller frame 6. Hereinafter, for the convenience of explaining the working mechanism of this embodiment, the combination of gears 10, roller 11 and roller shaft 5 will still be referred to as a toothed roller.

[0043] Please see Figure 4 The aluminum ingot forming device contains a first plate 12. Specifically, the first plate 12 is fixed to the main frame 1 and is adjacent to the mold 8 located below the toothed roller. Please refer to [link to relevant documentation]. Figure 4-7A second plate 13 is provided between the first plate 12 and the mold 8. The second plate 13 has a second rod 16, which is rotatably connected to the main frame 1. When the toothed roller rotates, the second plate 13 rotates up and down alternately when it contacts different molds 8.

[0044] Please see Figure 4 A sleeve 4 is provided at the first plate 12. A first one-way valve 17 is embedded in the end of the sleeve 4 away from the first plate 12. In addition, there is a second one-way valve 18. The second one-way valve 18 is arranged in a ring array at the sleeve 4, and the exhaust direction of the second one-way valve 18 points to the mold 8 located above the toothed roller.

[0045] It should be noted that the sleeve 4 is provided with a piston 21 that slides in cooperation with the sleeve 4. When the piston 21 slides down or up in the sleeve 4, air is injected into the sleeve 4 by the first one-way valve 17 or air is discharged out by the second one-way valve 18.

[0046] The sliding of piston 21 is achieved by connecting rod 19, that is, by connecting rod 19 to the second plate 13 to obtain kinetic energy. Specifically, connecting rod 19 is provided between the second plate 13 and piston 21. The two ends of connecting rod 19 are rotatably connected to the second plate 13 and piston 21 respectively (the second plate 13 has a transition buckle 20, so one end of connecting rod 19 is actually rotatably connected to the transition buckle 20). When the second plate 13 rotates up or down, piston 21 slides up or down in sleeve 4.

[0047] As described in Embodiment 1, during the contact between the second plate 13 and another mold 8, the second plate 13 slides from the previously contacted mold 8 to a fixed distance between the molds 8, and then rises to the next mold 8. This process is essentially a reciprocating up-and-down rotation. Accordingly, the connecting rod 19 intercepts some kinetic energy, causing the piston 21 to slide reciprocally within the sleeve 4. Air is injected into the sleeve 4 through the first one-way valve 17, or air is discharged outwards through the second one-way valve 18. Figure 4 As shown, the second one-way valve 18 points to the upper mold 8. After the molten aluminum is poured, the upper mold 8 needs to dissipate heat quickly so that the molten aluminum can solidify. By guiding the airflow to blow directly to the bottom of the mold 8, on the one hand, the mold 8 can dissipate heat quickly, and on the other hand, it avoids the airflow blowing directly to the mold 8 from above, which would cause the molten aluminum to fluctuate and affect the forming state of the aluminum ingot.

[0048] Example 2 is an extended example of Example 1. Therefore, Example 1 can be implemented alone or in combination with Example 2.

[0049] In Embodiments 1 and 2, mold brackets 9 are installed at both ends of the mold 8. The mold brackets 9 are fastened into the openings of the chains 2, so that the mold 8 is suspended between the two chains 2. In addition, the opening of the mold 8 always faces away from the toothed roller.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
