Description

Technical Field

[0001] This invention relates to the technical field of aluminum-clad steel wire processing equipment, specifically to a pre-stranded aluminum-clad steel wire round end processing device. Background Technology

[0002] Aluminum-clad steel is a composite product made by coating a layer of aluminum onto steel. It is typically a round wire, meaning a round steel wire is coated with a layer of aluminum, hence the name aluminum-clad steel wire or aluminum-clad steel cable (for electrical materials, it's commonly referred to as wire). The manufacturing method involves coating a layer of aluminum onto a steel wire using the conclad extrusion method. Powder metallurgy technology can also be used to coat aluminum powder onto the steel wire. After aluminum coating, it can be cold-drawn to improve strength. This is a relatively difficult type of metal wire to manufacture, especially in terms of controlling the surface quality of the steel wire, wire drawing lubrication, and preventing wire breakage during subsequent applications. Aluminum-clad steel has advantages such as high strength, good corrosion resistance, and superior electrical performance compared to galvanized steel wire. Because there are many combinations of aluminum layer thickness and steel wire strength, it offers great design flexibility. Aluminum-clad steel wire is commonly used in overhead line products, including conductor reinforcing cores, ground wires, and transmission lines, and can also be used as catenary wires or guy wires. The existing aluminum-clad steel wires can be processed into power transmission cables by a tube stranding device after forming. When the tube stranding device is in use, the aluminum-clad steel wires are fixed by the wire feeding reel, and then the aluminum-clad steel wires pass through the guide rollers to the wire stranding die. As the tube rotates, the aluminum-clad steel wires are stranded.

[0003] Existing aluminum-clad steel wire stranding processing equipment has poor stability of the aluminum-clad steel wire during pre-stretching and coiling, and the aluminum-clad steel wire is prone to damage. Summary of the Invention

[0007] Furthermore, the outer wall of the support block is provided with a first rotating shaft on the side away from the elliptical sphere, the inner wall of the first support sphere is provided with a first mounting groove that matches the first rotating shaft, the two ends of the major axis of the outer wall of the elliptical sphere are symmetrically provided with second rotating shafts, the inner wall of the support block is provided with a second mounting groove that matches the second rotating shaft, the outer wall of the first rotating shaft is provided with a first support ring, the outer wall of the second rotating shaft is provided with a second support ring, and the first rotating shaft and the second rotating shaft are perpendicular to each other; this can effectively ensure the stability of the omnidirectional rolling of the rolling frame.

[0008] Furthermore, the outer diameter of the second support ball is smaller than the outer diameter of the first support ball, and the outer diameter of the second support ball is greater than half of the outer diameter of the first support ball; this ensures the stability of the universal connection between the first support ball and the second support ball.

[0009] Furthermore, the springs are distributed in a frustum shape, with the dome of the frustum shape located inside the second support ball and the bottom of the frustum shape located inside the second guide ring.

[0010] Furthermore, the wire feeding frame includes a disc, and the outer wall of the disc is provided with a plurality of rotatably connected support shafts. The outer wall of the disc is provided with a third wire guide frame rotatably connected to the support shafts. The third wire guide frame includes a second wire block. The outer wall of the second wire block is provided with a second guide groove that matches the aluminum-clad steel wire. The two ends of the second wire block are symmetrically provided with second support frames.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] 1. This invention, by setting up a round-head wire-jointing die, a first round-head guide frame, a second round-head guide frame, a first guide ring, a first lead wire frame, a second guide ring, and a second lead wire frame, achieves round-head processing of the aluminum-clad steel wire. The first lead wire frame guides the aluminum-clad steel wire, effectively enhancing its guiding stability before winding and joining, thus preventing damage. The aluminum-clad steel wire moves under the traction of the take-up frame, exerting force on the surface of the first support ball. The force on the first support ball is transmitted to the second support ball, where a spring provides elastic buffering. The ball and spring work together to effectively enhance the multi-angle auxiliary guidance of the aluminum-clad steel wire, thereby improving its stability and preventing damage. Simultaneously, when the aluminum-clad steel wire contacts the surface of the first support ball, the rolling frame also contacts the surface of the aluminum-clad steel wire. During the movement of the aluminum-clad steel wire, the elliptical ball contacts its surface, guiding the wire's rolling motion. The support block provides rotational support to the elliptical ball, allowing the rolling frame to perform multi-angle rolling assistance. This effectively enhances the smoothness and stability of the aluminum-clad steel wire's movement, preventing damage. The use of an elliptical ball on the contact surface effectively increases the contact area, further ensuring the stability of the aluminum-clad steel wire.

[0017] 2. This invention utilizes a disc, support shaft, third lead frame, fixing ring, pre-twisted ring, fourth lead frame, ring rack, servo motor, and gears. The aluminum-clad steel wire passes through the third lead frame and moves towards the lead frame. After passing through the fourth lead frame of the pre-twisted ring, the aluminum-clad steel wire undergoes pre-twisting. The fixing ring provides rotational support for the pre-twisted ring, ensuring its stability. The servo motor drives the gears to rotate, which in turn drives the ring rack to rotate, which in turn drives the pre-twisted ring to rotate, thus achieving the pre-twisting of the aluminum-clad steel wire. The operation is convenient and quick. Attached Figure Description

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.

[0028] like Figures 1-3 and Figures 6-7 The device shown is a pre-stranded aluminum-clad steel wire round end processing device, including a base 1. The top of the base 1 is sequentially provided with a wire feeding frame 2, a wire guide frame 3, a pre-stranding frame 4, a wire paralleling frame 5, and a wire take-up frame 6. A round end paralleling mold 7 is provided on the paralleling frame 5. A first round end guide frame 8 is provided on the outer wall of the round end paralleling mold 7 near the pre-stranding frame 4, and a second round end guide frame 9 is provided on the outer wall of the round end paralleling mold 7 away from the pre-stranding frame 4. The first round end guide frame 8 includes a first guide ring 10, and a plurality of first wire guide frames 11 are provided on the inner wall of the first guide ring 10. Each first wire guide frame 11 includes a first wire guide block 12. The outer wall of the first wire guide block 12 is provided with a first guide groove 13 that matches the aluminum-clad steel wire. First support frames 14 are symmetrically provided at both ends of the first wire guide block 12. The first wire guide block 12 and the first support frame 14 are rotatably connected. The first support frame 14 and the first guide... The ring 10 is fixedly connected. The second round-headed guide frame 9 includes a second guide ring 15. The inner wall of the second guide ring 15 is provided with a plurality of second lead frames 16. The second lead frame 16 includes a first support ball 17 and a second support ball 18. The inner wall of the first support ball 17 is provided with a spherical groove matching the second support ball 18 on the side near the second guide ring 15. The second support ball 18 extends to the outside of the first support ball 17. The outer wall of the second support ball 18 is provided with a plurality of springs 19 on the side away from the first support ball 17. One end of the spring 19 is fixedly connected to the inner wall of the second guide ring 15. The outer wall of the first support ball 17 is movably provided with a plurality of rolling frames 20 on the outside of the second support ball 18. The rolling frame 20 includes a support block 21. The support block 21 is rotatably connected to the first support ball 17. The outer wall of the support block 21 is provided with an elliptical ball 22 that is rotatably connected.

[0029] The outer wall of the support block 21, away from the elliptical sphere 22, has a first rotating shaft. The inner wall of the first support sphere 17 has a first mounting groove that matches the first rotating shaft. The outer wall of the elliptical sphere 22 has symmetrically arranged second rotating shafts at both ends of its major axis. The inner wall of the support block 21 has a second mounting groove that matches the second rotating shaft. The outer wall of the first rotating shaft has a first support ring, and the outer wall of the second rotating shaft has a second support ring. The first rotating shaft and the second rotating shaft are perpendicular to each other. The first rotating shaft provides rotational support for the support block 21, ensuring the stability of the rotation of the support block 21. The first mounting groove provides installation space for the first rotating shaft. The first support ring provides guiding support on the outside of the first rotating shaft, further enhancing the stability of the first rotating shaft. The second rotating shaft provides rolling support for the elliptical sphere 22, ensuring the stability of the rolling of the elliptical sphere 22. The second mounting groove provides installation space for the second rotating shaft. The second support ring provides guiding support on the outside of the second rotating shaft, further enhancing the stability of the second rotating shaft. The first rotating shaft and the second rotating shaft are perpendicular to each other, so that the rotation directions of the support block 21 and the elliptical sphere 22 are perpendicular to each other, which can effectively ensure the omnidirectional rolling of the rolling frame 20.

[0030] The outer diameter of the second support ball 18 is smaller than that of the first support ball 17, and the outer diameter of the second support ball 18 is greater than half of the outer diameter of the first support ball 17. This makes the first support ball 17 and the second support ball 18 work together to achieve better processing results and ensures the stability of the universal connection between the first support ball 17 and the second support ball 18.

[0031] The spring 19 is distributed in a frustum shape, with the dome of the frustum shape located inside the second support ball 18 and the bottom of the frustum shape located inside the second guide ring 15. The frustum shape distribution of the spring 19 can effectively enhance the support stability of the spring 19 on the second support ball 18, thereby improving the stability of the second lead frame 16.

[0032] The specific implementation method is as follows: By setting up a round-head paralleling die 7, a first round-head guide frame 8, a second round-head guide frame 9, a first guide ring 10, a first lead wire frame 11, a second guide ring 15, and a second lead wire frame 16, in use, the aluminum-clad steel wire coil to be stranded is placed on the pay-off frame 2 for pay-off processing. The aluminum-clad steel wire passes through the conductor frame 3, the pre-stretching frame 4, and the paralleling frame 5, and is then taken up on the take-up frame 6. The conductor frame 3 guides the aluminum-clad steel wire, the pre-stretching frame 4 pre-stretches the aluminum-clad steel wire, the pre-stretched aluminum-clad steel wire passes through the paralleling frame 5 for paralleling processing, and the pre-stretched and paralleled aluminum-clad steel wire is then taken up on the take-up frame 6. Wire winding process: After pre-twisting, the aluminum-clad steel wire bundle is wound into the paralleling frame 5. The aluminum-clad steel wire first passes through the first round-head guide frame 8, then through the round-head paralleling die 7, and then exits from the second round-head guide frame 9, achieving the round-head processing of the aluminum-clad steel wire. When the aluminum-clad steel wire passes through the first round-head guide frame 8, the first lead frame 11 in the first round-head guide frame 8 guides the aluminum-clad steel wire, which can effectively enhance the guiding stability of the aluminum-clad steel wire before winding and paralleling, thereby reducing the stability of the aluminum-clad steel wire during pre-twisting and paralleling, thus avoiding damage to the aluminum-clad steel wire. The first support frame 14 of the first lead frame 11 supports the first lead wire. Block 12 provides rotational support, allowing the aluminum-clad steel wire to pass through the first lead frame 11 during movement. The aluminum-clad steel wire slides on the first lead block 12 of the first lead frame 11, and the first guide groove 13 on the first lead block 12 guides the aluminum-clad steel wire, effectively achieving rolling guidance and further enhancing its stability. When the aluminum-clad steel wire passes through the second round-headed guide frame 9, its surface contacts the surface of the second lead frame 16. The second guide ring 15 supports the second lead frame 16. When the aluminum-clad steel wire contacts the surface of the second lead frame 16, it moves along the take-up frame. Under the traction of 6, the aluminum-clad steel wire exerts force on the surface of the first support ball 17, and the force on the first support ball 17 is transmitted to the second support ball 18. The spring 19 provides elastic buffering for the second support ball 18, and the positions of the first support ball 17 and the second support ball 18 are displaced. When the aluminum-clad steel wire is wound up, due to the gradual change in the outer diameter of the winding, the movement angle of the aluminum-clad steel wire after winding is constantly changing. The first support ball 17, the second support ball 18, and the spring 19 work together to effectively enhance the multi-angle auxiliary guidance of the aluminum-clad steel wire, thereby effectively enhancing the stability of the aluminum-clad steel wire and avoiding damage to the aluminum-clad steel wire.Simultaneously, when the aluminum-clad steel wire contacts the surface of the first support ball 17, the rolling frame 20 also contacts the surface of the aluminum-clad steel wire. During the movement of the aluminum-clad steel wire, the elliptical ball 22 contacts the surface of the aluminum-clad steel wire, guiding its rolling motion. At the same time, the support block 21 provides rotational support for the elliptical ball 22, allowing the rolling frame 20 to perform multi-angle rolling assistance. This effectively enhances the smoothness and stability of the aluminum-clad steel wire's movement, thus preventing damage to the wire. The use of the elliptical ball 22 on the contact surface with the aluminum-clad steel wire effectively increases the contact area, further ensuring the stability of the wire.

[0033] As attached Figure 1 and Figures 4-5 The diagram illustrates a pre-stranded aluminum-clad steel wire rounding head processing device. The wire feeding frame 2 includes a disc 23. The outer wall of the disc 23 has several rotatably connected support shafts 24.

Second support frames are symmetrically located at both ends of the second wire guide block. The second wire guide block is rotatably connected to the second support frames, and the second support frames are fixedly connected to the disc 23. The third wire guide frame 25 guides the aluminum-clad steel wire, and the second support frames provide rotatable support for the second wire guide block, allowing the aluminum-clad steel wire to... During the movement, the aluminum-clad steel wire passes through the third lead frame 25 and slides on the second lead block of the third lead frame 25. The second guide groove on the second lead block guides the aluminum-clad steel wire, which can effectively achieve the rolling guidance of the aluminum-clad steel wire and further enhance the stability of the aluminum-clad steel wire. The inner wall of the pre-twisted frame 4 is provided with a fixing ring 26, the inner wall of the fixing ring 26 is provided with a pre-twisted ring 27 rotatably connected, the inner wall of the pre-twisted ring 27 is provided with several fourth lead frames 28 rotatably connected, the outer wall of the pre-twisted ring 27 is provided with an annular rack 29, the top of the base 1 is provided with a servo motor 30, and the outer wall of the output shaft of the servo motor 30 is fitted with a gear 31 that matches the annular rack 29.

The installation cavity 34 communicates with the annular groove 33. The annular groove 33 provides installation and movement space for the pre-winding ring 27 and the annular rack 29. The installation cavity 34 provides installation space for the gear 31, ensuring that the gear 31 can drive the annular rack 29 to move.

[0035] The outer wall of the conductor frame 3 has through holes that match the aluminum-clad steel wire, and the outer wall of the take-up frame 6 is provided with a take-up roller 32. The through holes allow the aluminum-clad steel wire to pass through, and the take-up roller 32 performs take-up processing on the aluminum-clad steel wire.

[0036] The fourth lead frame 28 includes a third lead block. The outer wall of the third lead block is provided with a third guide groove that matches the aluminum-clad steel wire. The third lead block is symmetrically provided with third support frames at both ends. The third lead block and the third support frames are rotatably connected. The third support frames are fixedly connected to the pre-twisted ring 27. The third support frames provide rotatable support for the third lead block, so that during the movement of the aluminum-clad steel wire, the aluminum-clad steel wire passes through the fourth lead frame 28 and slides on the third lead block of the fourth lead frame 28. The third guide groove on the third lead block guides the aluminum-clad steel wire, which can effectively realize the rolling guidance of the aluminum-clad steel wire and further enhance the stability of the aluminum-clad steel wire.

[0037] The specific implementation method is as follows: In use, a disc 23, a support shaft 24, a third lead frame 25, a fixing ring 26, a pre-twisted ring 27, a fourth lead frame 28, a ring rack 29, a servo motor 30, and a gear 31 are set up. The disc 23 supports the support shaft 24, which is used to place the aluminum-clad steel wire coil to be twisted. The aluminum-clad steel wire passes through the third lead frame 25 and moves towards the conductor frame 3. After passing through the fourth lead frame 28 of the pre-twisted ring 27, the aluminum-clad steel wire undergoes pre-twisting. The fixing ring 26 provides rotational support for the pre-twisted ring 27 to ensure its stability. The servo motor 30 drives the gear 31 to rotate, which in turn drives the ring rack 29 to rotate. The ring rack 29 then drives the pre-twisted ring 27 to rotate, thereby achieving the pre-twisting of the aluminum-clad steel wire. The operation is convenient and quick.
