Description

Technical Field

[0001] This application relates to the field of cable conductor manufacturing technology, and in particular to a process and equipment for preventing the twisting of alloy copper stranded conductors. Background Technology

[0002] Copper alloy stranded conductors are widely used in power transmission and communication due to their excellent electrical conductivity and mechanical strength. Currently, the industry mainly uses stranding machines to strand multiple copper wires into a conductor. However, during the stranding process, uneven tension or equipment vibration can easily cause the conductor to twist and deform, affecting its electrical and mechanical properties. In recent years, with the increasing demand for power transmission, the quality requirements for conductors have become increasingly stringent, making the solution to the twisting problem during stranding a key technical challenge.

[0003] Currently, the industry mainly uses the following two methods to solve the conductor twisting problem: one is to improve the tension control system of the stranding machine to keep the tension of each copper wire uniform; the other is to add a straightening device after stranding to correct the twisted conductor. Although the first method can reduce twisting, it requires high equipment precision and cannot completely eliminate twisting; the second method increases the production process, reduces production efficiency, and may damage the conductor surface during the straightening process.

[0004] Therefore, this application provides a process and equipment for preventing the twisting of alloy copper stranded conductors. Summary of the Invention

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The anti-twisting production process and equipment for alloy copper stranded conductors described in this application, by setting a tension adjustment mechanism and an anti-twisting mechanism, allows for the stranding of several alloy copper wires by the stranding machine body during stranding. Furthermore, during the stranding process, the tension of the alloy copper wires can be adjusted by driving the adjusting roller through the extension and retraction of a hydraulic rod, effectively preventing twisting and deformation of the alloy copper stranded conductor during production, thus improving the electrical and mechanical properties of the conductor. After stranding, the rotation of a small motor drives the bidirectional threaded column to rotate, which in turn moves two sliders simultaneously towards the center, achieving straightening of the stranded copper wires. This reduces subsequent straightening processes, improves production efficiency, and lowers production costs.

[0035] 2. The anti-twisting production process and equipment for alloy copper stranded conductors described in this application, by setting up a dust removal mechanism, during the process of driving the stranding spindle to rotate through the drive mechanism, the rotation of the stranding spindle can drive the rotation of the annular internal gear ring, the rotation of the annular internal gear ring can drive the rotation of the gear disc and the reciprocating screw, the rotation of the reciprocating screw can drive the sliding disc to move back and forth, and the back and forth movement of the sliding disc can drive the piston disc to move back and forth through the connecting rod. When the piston disc moves to the right, it can fill the annular air pipe with air from the annular hollow cylinder through the air filling pipe, and automatically spray it onto the surface of the alloy copper wire through the dust removal nozzle, so as to achieve the purpose of automatically cleaning the dust on the surface of the alloy copper wire before stranding, and ensuring the quality of the alloy copper conductor after stranding.

[0036] 3. The anti-twisting production process and equipment for alloy copper stranded conductors described in this application, by setting up a dust suction mechanism, during the process of driving the stranding main shaft to rotate through the drive mechanism and realizing automatic dust removal, the rotation of the guide plate can drive the bevel gear ring to rotate. The rotation of the bevel gear ring drives the second bevel gear and the vertical shaft to rotate. The rotation of the vertical shaft drives the rotating shaft to rotate under the action of the two first bevel gears. The rotation of the rotating shaft drives the suction fan blades to suck air into the dust collection box, creating a negative pressure inside the dust collection box. This allows the dust collection box to automatically adsorb the blown dust through the vertical suction pipe, the annular suction pipe, and the suction hole, and collect it through the dust collection bag, thereby achieving the purpose of automatic dust collection.

[0077] This application also proposes a process for preventing the twisting of alloy copper stranded conductors, including the following steps:

[0078] S1. Install the copper wire reel on the positioning frame on the stranding spindle 102 inside the machine body 101, and let the copper wire pass through the outer shell of the machine body 101, the adjusting roller 204, the guide plate 105, the stranding mold 103 and the pressing roller 302 in sequence.

[0079] S2. Start the winch;

[0080] S3. Start the hydraulic rod 202, and control and adjust the pressure between the adjusting roller 204 and the copper wire according to the tension sensor and PLC controller;

[0081] S4. Start the small motor 303 to drive the two pressing rollers 302 to move towards the center at the same time, applying radial pressure to the conductor;

[0082] S5. After stranding is complete, turn off the equipment and remove the finished conductor.

[0083] Working principle:

[0084] When stranding alloy copper wires, several alloy copper wires can be stranded together by the stranding machine body 100. During the stranding process, the tension of the alloy copper wires can be adjusted by the extension and retraction of the hydraulic rod 202 driving the adjusting roller 204, effectively preventing the twisting and deformation of the alloy copper stranded conductor during production, and improving the electrical and mechanical properties of the conductor. After stranding, the rotation of the small motor 303 drives the bidirectional threaded column 306 to rotate, and the rotation of the bidirectional threaded column 306 drives the two sliders 304 to move towards the center simultaneously. This achieves straightening of the stranded copper wire, reducing subsequent straightening processes, improving production efficiency, and lowering production costs. Furthermore, during the rotation of the stranding spindle 102 driven by the drive mechanism, the rotation of the stranding spindle 102 drives the annular internal gear ring 4014 to rotate. The rotation of the annular internal gear ring 4014 drives the gear disc 4013 and the reciprocating screw 4011 to rotate. The rotation of the reciprocating screw 4011 drives the sliding disc 406 to move back and forth. The back and forth movement of the sliding disc 406 drives the piston disc 407 to move back and forth via the connecting rod 408. When the piston disc... When 407 moves to the right, air from the annular hollow cylinder 405 is introduced into the annular air pipe 403 through the air filling pipe 409, and automatically sprayed onto the surface of the alloy copper wire through the dust removal nozzle 404. This achieves the purpose of automatically cleaning the dust on the surface of the alloy copper wire before stranding, ensuring the quality of the alloy copper conductor after stranding. Simultaneously, during the process of driving the stranding spindle 102 to rotate through the drive mechanism and achieving automatic dust removal, the rotation of the guide plate 105 drives the bevel gear ring 5014 to rotate, and the rotation of the bevel gear ring 5014 drives the... The rotation of the two bevel gears 5013 and the vertical shaft 5011, under the action of the two first bevel gears 5012, drives the rotating shaft 509 to rotate. The rotation of the rotating shaft 509 drives the suction fan blades 5010 to suck air into the dust collection box 501, creating a negative pressure inside the dust collection box 501. This causes the dust collection box 501 to automatically adsorb the blown dust through the vertical suction pipe 504, the annular suction pipe 502, and the suction hole 503, and collect it through the dust collection bag 505, thereby achieving the purpose of automatic dust collection.
