Description

Technical Field

[0001] This utility model relates to the field of aluminum product processing technology, specifically to a grain refiner addition device for aluminum liquid chute. Background Technology

[0002] Adding grain refiners such as aluminum-titanium-boron wire to the molten aluminum in the chute can refine the grain size of aluminum and its alloys after solidification. The fine and uniform grain structure can improve the tensile strength, yield strength and ductility of aluminum products, and make aluminum products easier to deform uniformly in subsequent rolling and forging, reducing cracks.

[0003] In existing technologies, the introduction position of the aluminum-titanium-boron (ATiB) wire is fixed. The ATiB wire is directly introduced into the aluminum molten chute for melting. Because the introduction position of the ATiB wire is fixed, the wire exhibits localized enrichment in the aluminum molten metal, making it difficult to achieve uniform distribution. This uneven distribution weakens the effective effect of the grain refiner, resulting in unstable grain refinement in the casting structure, ultimately negatively impacting the product quality of the aluminum plate casting. Summary of the Invention

[0004] This invention addresses the problem of uneven distribution of aluminum-titanium-boron wires in molten aluminum when added from a fixed position; it provides a grain refiner addition device for molten aluminum chute, which can prevent localized enrichment of aluminum-titanium-boron wires in molten aluminum and improve the quality of subsequent products.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A grain refiner addition device for an aluminum molten chute includes a chute, vertical plates, a housing, and a driving component. Each side plate of the chute has a vertical plate fixed to its upper end. Connecting plates are connected between the front and rear portions of two vertical plates. A rotating rod is provided between the two connecting plates, and a driving wheel is fitted on each of the two rotating rods. The two driving wheels are opposite each other. Movable plates are symmetrically rotated on opposite sides of the two connecting plates. The two movable plates are connected to a housing with openings at their upper and lower ends. The driving component includes a driving rod and a first spur gear. The driving rod is located between the rear portions of the two rotating rods and drives the rear movable plate to rotate. A first spur gear is fitted on the peripheral wall of the driving rod. A sector gear with an upward protrusion is fixed on the rotating rod to the left of the first spur gear. When the sector gear protrudes to the right, it meshes with the first spur gear. A sector gear with a downward protrusion is fixed on the rotating rod to the right of the first spur gear. When the sector gear protrudes to the left, it meshes with the first spur gear.

[0007] Furthermore, the rear end of the left rotating rod is rotatably connected to the rear connecting plate, and the front side of the left rotating rod is provided with a motor fixed to the rear side of the front connecting plate. The output end of the motor is fixedly connected to the front end of the left rotating rod, and the two ends of the right rotating rod are rotatably connected to the front and rear connecting plates respectively. Both rotating rods are fitted with and fixed with two spherical gears, and the two spherical gears mesh with each other.

[0008] Furthermore, each of the movable plates is rotatably connected to the connecting plate on the same side via a pivot that passes through the connecting plate on the same side, and the rear end of the drive rod is fixedly connected to the front end of the pivot on the rear side.

[0009] Furthermore, the lower ends of the two movable plates are respectively connected to the upper ends of the front and rear side plates of the housing.

[0010] Furthermore, when the protrusion of the second sector gear faces downward, the teeth at the left end of the second sector gear disengage from the teeth of the first circumferential gear, the protrusion of the first sector gear faces upward, and the teeth at the right end of the first sector gear mesh with the teeth of the first circumferential gear. The lower end of the housing tilts to the left and approaches the left side upright plate.

[0011] Furthermore, the housing is lower than the connecting plate, the drive wheel is a ring with a groove on its outer surface, and when the housing is in a vertical state, the housing is located directly below the two drive wheels.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This invention uses a motor to drive two rotating rods to rotate relative to each other, and two drive wheels to rotate relative to each other, thereby driving aluminum-titanium-boron wires downward into the chute. While the two rotating rods are rotating relative to each other, the housing is driven to swing back and forth to the left or right. The aluminum-titanium-boron wires moving downward through the housing are swung left or right into the chute, improving the uniformity of the addition of aluminum-titanium-boron wires to the aluminum liquid, avoiding local enrichment of aluminum-titanium-boron wires in the aluminum liquid, and improving the quality of subsequent products.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1-3 As shown, a grain refiner addition device for an aluminum molten metal chute includes a chute 1, a vertical plate 2, a housing 3, and a driving component. Each side plate of the chute 1 has a vertical plate 2 fixed to its upper end. The vertical plate 2 is a rectangular plate. Connecting plates 4, also rectangular, are connected between the front and rear of two vertical plates 2. Rotating rods 5, round rods, are provided between the two connecting plates 4 and rotate relative to each other. Driving wheels 6 are fitted onto both rotating rods 5, which are positioned opposite each other. Movable plates 7, also rectangular, are symmetrically rotated on opposite sides of the two connecting plates 4. Two movable plates 7 are connected together to the housing 3 with openings at the top and bottom. The housing 3 is a rectangular shell. The driving component includes a driving rod 8 and a spur gear 9. The driving rod 8 is located between the rear parts of the two rotating rods 5 and drives the rear movable plate 7 to rotate. A spur gear 9 is sleeved on the peripheral wall of the driving rod 8. A sector gear 10 with its protrusion facing upward is fixed on the rotating rod 5 to the left of the spur gear 1. When the sector gear 10 protrudes to the right, it meshes with the spur gear 9. A sector gear 21 with its protrusion facing downward is fixed on the rotating rod 5 to the right of the spur gear 1. When the sector gear 21 protrudes to the left, it meshes with the spur gear 9.

[0020] The rear end of the left rotating rod 5 is rotatably connected to the rear connecting plate 4. The front side of the left rotating rod 5 is provided with a motor 12 fixed to the rear side of the front connecting plate 4. The output end of the motor 12 is fixedly connected to the front end of the left rotating rod 5. The two ends of the right rotating rod 5 are rotatably connected to the front and rear connecting plates 4 respectively. Both rotating rods 5 are fitted with and fixed with two spur gears 13, which mesh with each other. The tip circle diameters of the two spur gears 13 are the same.

[0021] Each of the movable plates 7 is rotatably connected to the connecting plate 4 on the same side via a rotating shaft 15 that passes through the connecting plate 4 on the same side. The rear end of the drive rod 8 is fixedly connected to the front end of the rear rotating shaft 15. The upper end of each movable plate 7 is in sliding contact with the connecting plate 4 on the same side.

[0022] The lower ends of the two movable plates 7 are respectively connected to the upper ends of the front and rear side plates of the housing 3.

[0023] When the protrusion of sector gear 11 is facing downward, the teeth at the left end of sector gear 11 disengage from the teeth of spur gear 9, the protrusion of sector gear 10 faces upward, and the teeth at the right end of sector gear 10 mesh with the teeth of spur gear 9. The lower end of housing 3 tilts to the left and approaches the left side plate 2. The tip circle diameters of sector gear 10 and sector gear 11 are the same.

[0024] The housing 3 is lower than the connecting plate 4. The drive wheel 6 is a ring with a groove 14 on its outer surface. The drive wheel is fixedly connected to the rotating rod via the inner ring. When the housing 3 is in a vertical state, the housing 3 is located directly below the two drive wheels 6.

[0025] In use, the end of the aluminum-titanium boron wire (grain refiner) passes between the two drive wheels 6, and the grooves 14 on the two drive wheels 6 press against the peripheral wall of the aluminum-titanium boron wire. Then, it passes through the housing 3 from top to bottom and extends into the chute 1. The motor 12 drives the left rotating rod 5 to rotate clockwise (the clockwise rotation of the left rotating rod 5 is...). Figure 1 From the main viewpoint), because the two rotating rods 5 are meshed with the sprockets 13, when the left rotating rod 5 rotates clockwise, the right rotating rod 5 rotates counterclockwise. The two drive wheels 6 rotate relative to each other with the connected rotating rods 5, driving the aluminum titanium boron wire to move downwards, through the housing 3 into the chute 1. When the sector gear 10 rotates clockwise with the left rotating rod 5, with its protrusion facing upwards and its right teeth beginning to mesh with the sprocket 9, at this time, the sector gear 11 disengages from the sprocket. The sector gear 10 rotates with the connected rotating rod 5, and the meshing sprocket 9 drives the drive rod 8 to rotate counterclockwise (the counterclockwise rotation of the drive rod 8 is...). Figure 1 (From the main viewpoint), the drive rod 8 drives the rear movable plate 7 to rotate counterclockwise via the connected rotating shaft 15. The housing 3 rotates counterclockwise with the rear movable plate 7, and the aluminum titanium boron wire inside the housing 3 is pushed to swing to the right. As the sector gear 10 disengages from the spherical gear 9, the sector gear 21 protrudes upward, and the teeth at the left end of the sector gear 211 begin to mesh with the spherical gear 9, driving the spherical gear 9 to rotate clockwise. The drive rod 8 drives the housing 3 to rotate clockwise with the spherical gear 9, and the aluminum titanium boron wire inside the housing 3 swings to the left.

[0026] Therefore, when the motor 12 drives the two drive wheels 6 to rotate continuously relative to each other, it can drive the aluminum titanium boron wire to move into the chute 1, and drive the housing 3 to swing back and forth to the left or right. The housing pushes the aluminum titanium boron wire to swing to the left or right. Therefore, the aluminum titanium boron wire can be added evenly to the aluminum liquid in the chute 1, avoiding the addition of aluminum titanium boron wire at the same position and causing deposition.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
