Description

Technical Field

[0001] This utility model relates to the technical field of wire stripping equipment, and more specifically, to a centrifugal aluminum rod stripping mechanism for copper-aluminum alloy wire production. Background Technology

[0002] Copper-aluminum alloy wire, also known as copper-clad aluminum alloy wire, is a type of conductor consisting of an aluminum core wrapped with a thin layer of copper strip. Before being drawn thinner, the aluminum core is made of aluminum rod. Because the surface of the aluminum rod is prone to oxidation, it needs to be stripped before copper is clad onto it.

[0003] Currently, aluminum rod stripping equipment typically uses a turntable with several blades pointing towards its center. A through-hole is located at the center of the turntable. During stripping, the aluminum rod passes through the through-hole via a traction mechanism, with the blades pressing against it. A motor drives the turntable to rotate, which in turn rotates the blades to strip the aluminum rod. However, the blades are usually fixed to the turntable by clamps, requiring manual movement to bring the blade tip against the aluminum rod each time. Automatic pressing and rebound are not possible. Some stripping equipment, such as the anti-oxidation metal stripping machine for aluminum wire (publication number CN2305014Y), uses a movable adjusting sleeve with a spring to automatically press the blades against the aluminum rod. However, this structure does not automatically release and rebound the aluminum rod; manual upward movement of the blades is still required to release the rod. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a centrifugal aluminum rod peeling mechanism for copper-aluminum alloy wire production that can automatically press the cutting tool down on the aluminum rod and automatically remove the cutting tool from the aluminum rod after the turntable stops.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A centrifugal aluminum rod stripping mechanism for copper-aluminum alloy wire production includes:

[0007] Fixed base;

[0008] A turntable is rotatably mounted on the fixed base, and a through hole is provided in the center of the turntable for the aluminum rod to pass through;

[0009] At least one peeling assembly is arranged at intervals around the turntable's through-hole on the side of the turntable facing away from the fixed base; the peeling assembly includes a rotating shaft elastically rotatably mounted on the turntable, and a swing arm mounted on the rotating shaft and extending towards the aluminum rod, the end of the swing arm away from the rotating shaft being provided with a blade; and

[0010] A drive component, the output of which is connected to the turntable, is used to drive the turntable to rotate;

[0011] When the turntable is not rotating, the cutter and the aluminum rod are in a spaced-out state; when the turntable rotates, the centrifugal force causes the swing arm to swing toward the center of the turntable, thereby causing the cutter to press on the aluminum rod.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] Due to the elastic rotation setting of the rotating shaft, the cutter and aluminum rod are separated when the turntable is not rotating. After the drive component drives the turntable to rotate, due to centrifugal force, the swing arm will swing towards the center of the turntable, thus pressing the cutter onto the aluminum rod, realizing automatic downward pressing of the cutter without manual operation, making the operation more convenient. When peeling stops, the turntable stops rotating, and the swing arm loses centrifugal force. Due to the elastic rotation setting of the rotating shaft, the rotating shaft will automatically rotate back, thereby driving the swing arm to automatically swing upward, separating the cutter from the aluminum rod, realizing automatic rebound and ending the release operation of the aluminum rod, which facilitates the observation of the aluminum rod, material changing and other operations.

[0014] Preferably, the turntable is further provided with a connecting shaft that is rotatably connected to the fixed base, and the through hole is formed on the connecting shaft; the output end of the drive component is connected to the connecting shaft.

[0015] Preferably, a pulley is provided at one end of the connecting shaft that passes through the fixed base, and the output end of the drive assembly is connected to the pulley via the pulley.

[0016] Preferably, the rotating shaft is provided with a torsion spring for automatically rotating the shaft so that the tool leaves the aluminum rod.

[0017] Preferably, the turntable has a cavity; the torsion spring is disposed in the cavity, with one end fixed to the inner wall of the cavity and the other end fixed to the end of the rotating shaft away from the swing arm.

[0018] Preferably, an extension shaft is rotatably connected between the end of the rotating shaft away from the swing arm and the inner wall of the cavity, and the torsion spring is sleeved on the extension shaft.

[0019] Preferably, a first limiting member is provided in the cavity, and a second limiting member is provided on the rotating shaft to limit the rotation of the rotating shaft when the tool leaves the aluminum rod and abuts against the first limiting member.

[0020] Preferably, the end of the swing arm away from the rotating shaft is bent towards the turntable to form a connecting seat, and a pressure roller is rotatably mounted on the connecting seat; three peeling components are evenly spaced around the perimeter.

[0021] Preferably, the cutter is positioned on the side of the pressure roller away from the turntable.

[0022] Preferably, the end of the swing arm away from the pivot is provided with a slot for clamping a tool and a slit passing through the slot; the swing arm is also provided with a threaded part that narrows the slit and clamps the tool in the slot.

[0023] Preferably, the fixing base is disposed on the box body, and the turntable and peeling assembly are disposed inside the box body; the box body is also provided with a cover that encloses the turntable and peeling assembly inside the box body. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] refer to Figure 1-3 A centrifugal aluminum rod stripping mechanism for copper-aluminum alloy wire production includes: a fixed base 2, a turntable 3, at least one stripping component 4, and a drive component 5. The turntable 3 is rotatably mounted on the fixed base 2, and a through hole 31 for the aluminum rod 1 to pass through is opened in the center of the turntable 3. The stripping component 4 is arranged in a circle around the through hole 31 of the turntable 3 on the side of the turntable 3 away from the fixed base 2. The stripping component 4 includes a rotating shaft 41 elastically rotatably mounted on the turntable 3, and a swing arm 42 mounted on the rotating shaft 41 and extending in the direction close to the aluminum rod 1. A cutter 43 is provided at the end of the swing arm 42 away from the rotating shaft 41. The output end of the drive component 5 is connected to the turntable 3 to drive the turntable 3 to rotate. When the turntable 3 is not rotating, the cutter 43 and the aluminum rod 1 are in a spaced-out state. When the turntable 3 rotates, the centrifugal force causes the swing arm 42 to swing towards the center of the turntable 3, thereby pressing the cutter 43 onto the aluminum rod 1.

[0034] Understandably, the fixed base 2 is the base component that fixes the turntable 3. It can be a cylindrical structure or a block structure, but is not limited to these. The rotational arrangement between the turntable 3 and the fixed base, and between the rotating shaft 41 and the turntable 3, can be a direct shaft-hole fit, or a rotational fit via bearings, but is not limited to these. The elastic rotational arrangement of the rotating shaft 41 can be achieved by using a torsion spring 411 or a tension spring to rotate the shaft 41, but is not limited to these. The swing arm 42 extends towards the aluminum rod 1, reaching one side of the aluminum rod 1. The swing arm 42 is perpendicular to the rotating shaft 41, and the cutter 43 is perpendicular to the swing arm 42. These perpendicularities allow the cutter 43 to point towards the aluminum rod 1. The drive assembly 5 is the component that drives the turntable 3 to rotate. It can be a motor with a belt 51 drive structure, or a gear meshing structure, but is not limited to these.

[0035] For reference, please refer to this setting. Figure 5-6 Due to the elastic rotation setting of the rotating shaft 41, when the turntable 3 is not rotating, the cutter 43 is separated from the aluminum rod 1. After the drive component 5 drives the turntable 3 to rotate, due to centrifugal force, the swing arm 42 will swing towards the center of the turntable 3, thereby pressing the cutter 43 onto the aluminum rod 1, realizing the automatic downward pressing of the cutter 43. In conjunction with the rotation of the turntable 3, the aluminum rod 1 is peeled without the need for manual operation, making the operation more convenient. When peeling stops, the turntable 3 stops rotating, and the swing arm 42 loses centrifugal force. Due to the elastic rotation setting of the rotating shaft 41, the rotating shaft 41 will automatically rotate back, thereby driving the swing arm 42 to automatically swing upward, causing the cutter 43 to separate from the aluminum rod 1, realizing the automatic rebound to end the release operation of the aluminum rod 1, which facilitates the observation and material replacement of the aluminum rod 1.

[0036] In some embodiments, reference Figure 1 and Figure 4The turntable 3 is also equipped with a connecting shaft 32 that is rotatably connected to the fixed base 2, and a through hole 31 is formed on the connecting shaft 32. The output end of the drive assembly 5 is connected to the connecting shaft 32. Furthermore, a belt pulley 321 is provided at one end of the connecting shaft 32 that passes through the fixed base 2, and the output end of the drive assembly 5 is connected to the belt pulley 321 through the belt pulley 321. In this way, the drive assembly 5 drives the belt pulley 321 to rotate, which in turn drives the rotating shaft 41 and thus the turntable 3 to rotate.

[0037] In some embodiments, reference Figure 4 A torsion spring 411 is provided on the rotating shaft 41 to automatically rotate the rotating shaft 41, thereby causing the tool 43 to separate from the aluminum rod 1. Specifically, a cavity 33 is formed inside the turntable 3; the torsion spring 411 is disposed in the cavity 33, with one end fixed to the inner wall of the cavity 33 and the other end fixed to the end of the rotating shaft 41 away from the swing arm 42. The two ends of the torsion spring 411 are fixedly set, and can be directly welded to the inner wall of the cavity 33 and the rotating shaft 41, or limit holes can be provided on the inner wall of the cavity 33 and the rotating shaft 41 to insert the torsion spring 411 into the limit holes, etc., but not limited to these. When the swing arm 42 swings down to press the tool 43 onto the aluminum rod 1, the torsion spring 411 is in a tightened state. Thus, when the turntable 3 stops rotating, the torsion spring 411 resets, driving the rotating shaft 41 to rotate, thereby driving the swing arm 42 to swing up and separate the tool 43 from the aluminum rod 1.

[0038] In some embodiments, an extension shaft 412 is rotatably connected between the end of the rotating shaft 41 away from the swing arm 42 and the inner wall of the cavity 33, and a torsion spring 411 is sleeved on the extension shaft 412. It is understood that at least one end of the extension shaft 412 is rotatably mounted, either on the inner wall of the cavity 33 or on the rotating shaft 41. In this way, the extension rod does not affect the rotation of the rotating shaft 41 and can also stabilize the torsion spring 411.

[0039] In some embodiments, reference Figure 4-6 A first limiting member 44 is provided inside the cavity 33, and a second limiting member 45 is provided on the rotating shaft 41. When the tool 43 leaves the aluminum rod 1, it abuts against the first limiting member 44 and enters to limit the rotation of the rotating shaft 41. It can be understood that the first limiting member 44 and the second limiting member 45 can be a limiting block structure or a limiting rod structure. When the rotating shaft 41 is reset, it will drive the first limiting member 44 to abut against the second limiting member 45 to prevent the rotating shaft 41 from rotating excessively.

[0040] In some embodiments, reference Figure 2 , Figure 3 as well as Figure 5The end of the swing arm 42 away from the rotating shaft 41 is bent towards the turntable 3 to form a connecting seat 421. A pressure roller 422 is rotatably mounted on the connecting seat 421. Three peeling components 4 are evenly spaced around the aluminum rod 1. A blade 43 is positioned on the side of the pressure roller 422 away from the turntable 3. Understandably, it would be unstable for the blade 43 to directly press against the aluminum rod 1 for rotational peeling. By setting three peeling components 4, three pressure rollers 422 are positioned around and press against the aluminum rod 1. In this way, the pressure rollers 422 can first press against the aluminum rod 1 before the blade 43 peels the aluminum rod 1, ensuring the stability of the peeling process.

[0041] In some embodiments, reference Figure 2-3 The swing arm 42 has a slot 424 for clamping the tool 43 at the end away from the pivot 41, and a slot 423 passing through the slot 424. The swing arm 42 also has a threaded part 425 that narrows the slot 423 to clamp the tool 43 in the slot 424. The threaded part 425 can be a screw or a bolt with a nut locking structure. In this way, the tool 43 can move in the slot 424 to adjust the depth of the tool 43, thereby controlling the peeling thickness of the aluminum rod 1. After the position of the tool 43 is determined, the tool 43 is locked in the slot 424 by narrowing the slot 423 through the threaded part 425.

[0042] In some embodiments, reference Figure 1 The mounting base 2 is mounted on the housing 6, and the turntable 3 and peeling assembly 4 are both housed inside the housing 6. The housing 6 also has a cover that encloses the turntable 3 and peeling assembly 4 within it. This cover is not shown in the attached diagram; it is simply a component that seals an opening in the housing 6. Further details are omitted here. Thus, the housing 6 not only allows for the mounting base 2 to be installed but also enables the collection of peeled debris.

[0043] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
