Description

Technical Field

[0001] This utility model relates to the field of aluminum processing, and in particular to an anti-breakage mechanism for a wire feeder. Background Technology

[0002] In the process of casting aluminum ingots using molten aluminum, aluminum processing companies need to add a specific proportion of grain refiner to the molten aluminum to ensure a low grain size. Commercially available grain refiners are generally sold in the form of wire. The wire is wound into coils and continuously melted at a specific rate into the molten aluminum in the aluminum distribution pan for a specified length.

[0003] Typically, the finer wire is added to the aluminum liquid distribution plate via a wire feeder. Referring to Chinese Patent CN208814369 U, for cases with larger aluminum ingots, a wire feeder is used to simultaneously feed two wires into the aluminum liquid distribution plate via a wheel-type clamping mechanism.

[0004] However, when the feeder suddenly stops, the refining agent filament roll continues to rotate at a certain angle due to inertia, causing the refining agent filament between the feeder and the wheel clamping mechanism to hang downwards. The two filaments are prone to tangling, and the angle between the refining agent filament and the plane of the feeder's horizontal turntable is large. When the feeder restarts, the refining agent filament is easily broken, and the feeder needs to be re-fed.

[0005] Therefore, how to effectively avoid the occurrence of the above situations is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-breakage mechanism for a wire feeder. This mechanism has a simple structure, low processing cost, and can effectively prevent the breakage of the refining agent wire, thus meeting the production needs of enterprises.

[0007] The technical solution of this utility model is: an anti-breakage mechanism for a wire feeder, including a support plate disposed between the wire feeder and a wheeled clamping mechanism. The plane of the support plate is perpendicular to the feeding direction of the wire feeder and is close to the wire feeder. Both sides of the support plate are provided with first limiting rods extending upward from the top edge of the support plate. The middle of the support plate is provided with a second limiting rod extending upward from the top edge of the support plate. A support roller is disposed between the two first limiting rods, offset from the second limiting rod along the feeding direction of the wire feeder, and the support roller is higher than the top edge of the support plate.

[0008] The top of the support plate is provided with an upward-opening groove-shaped notch, and the plates on both sides of the support plate form the first limiting rod.

[0009] The height of the support roller is adapted to the feeding height of the wire feeder.

[0010] The mounting shaft of the support roller is welded to the side wall of the first limiting rod facing the wire feeder at both ends, and the second limiting rod is welded to the side of the support plate facing the wheel clamping mechanism, so that the support roller and the second limiting rod are misaligned along the feeding direction of the wire feeder.

[0011] The cross-section of the second limiting rod is circular.

[0012] The extension height of the second limiting rod exceeds the extension height of the first limiting rod, and the height of the support roller is lower than the extension height of the first limiting rod.

[0013] The above technical solution has the following beneficial effects: 1. The anti-breakage mechanism of the wire feeder includes a support plate disposed between the wire feeder and the wheel-type clamping mechanism. The refining agent wire roll is mounted on the wheel-type clamping mechanism. The wire feeder is used to pull the refining agent wire and continuously feed the refining agent wire of a specified length into the aluminum liquid separation plate. The plane of the support plate is perpendicular to the feeding direction of the wire feeder and is close to the wire feeder. Both sides of the support plate are provided with a first limiting rod extending upward from the top edge of the support plate, and the middle of the support plate is provided with a second limiting rod extending upward from the top edge of the support plate. The second limiting rod cooperates with the two first limiting rods on both sides to limit the horizontal position of the two refining agent wires and prevent the two refining agent wires from tangling and knotting. A support roller is installed between the two first limiting rods, offset from the second limiting rod along the feeding direction of the wire feeder. The support roller is higher than the top edge of the support plate. Two refining agent filaments are supported on the support roller, with their free ends entering the wire feeder. When the wire feeder suddenly stops, the refining agent filament roll continues to rotate at a certain angle under inertia, causing the refining agent filament between the support roller and the wheel-type clamping mechanism to hang downwards, while the refining agent filament between the support roller and the wire feeder remains in a normal state. This ensures that the angle between the refining agent filament and the wire feeder is normal, and the hanging section of the refining agent filament is connected to the normal section of the refining agent filament in an arc shape. This avoids the problem of the refining agent filament breaking due to excessive bending angle when the wire feeder restarts, thus meeting the production requirements of wire feeding.

[0014] 2. The top of the support plate is provided with an upward-opening groove-shaped notch. The plates on both sides of the support plate at the groove-shaped notch form the first limiting rod. This structure has the advantages of simple processing and low cost while satisfying the limiting of the finer agent filament.

[0015] 3. The height of the support roller is adapted to the feeding height of the wire feeder, so that when the wire feeder suddenly stops, the refining agent wire located between the support roller and the wire feeder is in a horizontal state, ensuring smooth feeding when the wire feeder restarts.

[0016] 4. The cross-section of the second limiting rod is circular, which reduces resistance and wear on the refining agent filaments.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0020] See Figures 1 to 4 This is a specific embodiment of an anti-breakage mechanism for a wire feeder. The anti-breakage mechanism includes a support plate 3 disposed between the wire feeder 1 and the wheeled clamping mechanism 2. Both the wire feeder and the wheeled clamping mechanism are conventional equipment in aluminum processing enterprises. The wire feeder is installed on a platform set on the factory floor, and the wheeled clamping mechanism is installed on a bracket set on the factory floor, with a gap between them. The plane of the support plate 3 is perpendicular to the feeding direction of the wire feeder 1 and is close to the wire feeder 1. Specifically, the support plate is fixed to the platform by welding. Both sides of the support plate 3 are provided with a first limiting rod 4 extending upward from the top edge of the support plate. In this embodiment, by providing an upward-opening groove-shaped notch 7 at the top of the support plate 3, the plates on both sides of the groove-shaped notch of the support plate form the first limiting rod 4. A second limiting rod 5 extending upward from the top edge of the support plate 3 is provided in the middle of the support plate 3. Specifically, the cross-section of the second limiting rod 5 is circular, and the second limiting rod 5 is welded to the side of the support plate 3 facing the wheel clamping mechanism. Typically, the second limiting rod is located between the two first limiting rods, and the extension height of the second limiting rod 5 exceeds the extension height of the first limiting rod 4. A support roller 6 is provided between the two first limiting rods 4, offset from the second limiting rod 5 along the feeding direction of the wire feeder 1, and the support roller 6 is higher than the top edge of the support plate 3. In this embodiment, the two ends of the mounting shaft of the support roller 6 are respectively welded to the side wall of the corresponding first limiting rod 4 facing the wire feeder, so that the support roller 6 and the second limiting rod 5 are offset along the feeding direction of the wire feeder. Furthermore, the height of the support roller 6 is adapted to the feeding height of the wire feeder 1, and the height of the support roller 6 is lower than the extension height of the first limiting rod 4.

[0021] The working principle of this invention is as follows: Two coils of refining agent wire are assembled on a wheel-type clamping mechanism. The free ends of the two coils pass through the limiting area between the corresponding first and second limiting rods and are fed to the wire feeder. The wire feeder continuously melts a specified length of refining agent wire into the molten aluminum in the aluminum slurry distribution plate at a specific rate. When the wire feeder suddenly stops, the refining agent wire coils continue to rotate at a certain angle under inertia, causing the refining agent wire between the support roller and the wheel-type clamping mechanism to droop downwards, while the refining agent wire between the support roller and the wire feeder remains in a normal state. This ensures that the angle between the refining agent wire and the wire feeder is normal, and the drooping section of the refining agent wire and the normal section of the refining agent wire are connected in an arc shape. When the wire feeder restarts, the refining agent wire will not be broken, thus meeting the production requirements for feeding wire from the molten aluminum.
