Abstract

This invention relates to a method for cutting a drop wire. A conveying module transports the drop wire to a cutting module, stopping the transport once the drop wire reaches a predetermined length. The cutting module then cuts the drop wire. A cutting clamping block on the cutting clamping part of the cutting module clamps the drop wire. A cutting break chuck on the cutting break part of the cutting module is pulled by a cutting break clamping cylinder to clamp the drop wire passing through the cutting break chuck. A cutting power supply provides power, heating the drop wire located between the cutting clamping part and the cutting break part. A cutting break driver in the cutting break part rotates the cutting break chuck to twist the drop wire located between the cutting clamping part and the cutting break part. A cutting break pulling cylinder fixed to the cutting mounting base of the cutting module pushes the cutting break part away from the cutting clamping part to break the drop wire, thus completing the cutting operation. Compared with the prior art, the drop wire cut by the present invention forms a frustum-shaped end at the cut point, which will not cause the strands to unravel and is conducive to subsequent threading operations.

Description

Technical Field

[0001] This invention relates to the field of overhead contact line dropper processing, and specifically to a method for cutting dropper wires. Background Technology

[0002] With the rapid development of high-speed rail technology in my country, newer and higher requirements have been placed on railway process quality and standards. In electrified railway lines, the overhead contact system is a crucial component ensuring normal railway operation. The contact system is connected to the electrified railway power supply line, providing power to electric locomotives and their auxiliary equipment. In the contact system, the dropper is a key factor in ensuring good contact between the contact system and the locomotive's pantograph. Every 6-8 meters along the line, an integral dropper is installed to suspend the contact wire from the catenary cable, ensuring the suspension height of the contact wire and maintaining a certain degree of elasticity to guarantee good contact between the contact system and the pantograph. The dropper includes the dropper wire, a heart-shaped ring and clamping tube on one or both sides of the dropper wire, and wire lugs at one or both ends of the dropper wire. The production process of droppers mainly consists of several steps: wire cutting, threading, tensioning, crimping, marking, and bundling. Threading involves passing the dropper wire through the crimping tube, heart-shaped ring, and lug. Tensioning refers to using the dropper wire to tighten the heart-shaped ring and crimping tube. Crimping involves pressing the crimping tube and lug tightly against the dropper wire. Currently, dropper production is primarily manual, typically employing four to five people per shift to perform the aforementioned steps. This production method suffers from high labor costs and low precision in finished droppers, particularly in the wire cutting and crimping stages. Manual production results in inconsistent and uneven lengths, weak crimping, or excessive crimping force leading to cracking of the crimping tube and / or lug. In the wire cutting process, the primary method is shearing, where manual cutting of the dropper wire is done using tools such as pliers. Manual wire cutting is inefficient and cannot meet the needs of automated production. More importantly, it causes the drop wire to unravel at the cut point, making subsequent threading difficult. This is especially true when the drop wire passes through the crimp tube and / or into the wire lug, where the unraveling strands at the end of the drop wire can cause significant interference.

[0003] In view of this, the present invention aims to provide a method for cutting suspension wire, which uses heating, twisting and breaking to achieve automatic cutting of the wire and form a frustoconical end at the cut point, thereby solving the technical problem of unraveling at the cut point of the suspension wire in the prior art and facilitating subsequent threading operations.

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1:

[0034] Reference Figures 1-7 As shown, an improvement of a method for cutting a drop wire is that the drop wire is conveyed to the cutting module 60 by the conveying module 30 and the conveying is stopped after the drop wire reaches the predetermined length of the wire being fed. The cutting module 60 then cuts the drop wire.

[0035] Step 1: The wire clamping movable block 613 on the wire clamping part 61 in the wire cutting module 60 clamps the suspension wire; Step 2: The wire breaking chuck 623 on the wire breaking part 62 in the wire cutting module 60 is pulled by the wire breaking clamping cylinder 6221 to clamp the suspension wire passing through the wire breaking chuck 623; Step 3: The wire cutting power supply part 64, the wire cutting power supply copper plate A641, the wire clamping part 61, the suspension wire located between the wire clamping part 61 and the wire breaking part 62, the wire breaking part 62 and the wire cutting power supply copper plate A641 in the wire cutting module 60... The circuit is formed by plate B642, and the power supply unit 64 supplies power. The suspension wire located between the wire clamping part 61 and the wire breakage part 62 heats up and softens. In step four, the wire breakage driver 6211 of the wire breakage part 62 drives the wire breakage chuck 623 to rotate to twist the suspension wire located between the wire clamping part 61 and the wire breakage part 62. In step five, the wire breakage cylinder 629 fixed on the wire mounting base 63 of the wire cutting module 60 pushes the wire breakage part 62 away from the wire clamping part 61 to break the suspension wire, thereby completing the cutting operation.

[0036] In this embodiment, the wire clamping part 61 is used to clamp the suspension wire to provide a fixed end for twisting and breaking the suspension wire; the wire breaking part 62 is used to clamp the suspension wire and twist and break it; the wire power supply part 64 is used to provide power for the heating of the suspension wire located between the wire clamping part 61 and the wire breaking part 62.

[0037] In this embodiment, after the suspension wire passes through the wire clamping part 61 and the wire breakage part 62, the wire clamping movable block 613 of the wire clamping part 61 clamps the suspension wire, thereby clamping and fixing one end of it; the wire breakage chuck 623 of the wire breakage part 62 clamps the other end of the suspension wire under the action of the wire breakage clamping cylinder 6221; the wire power supply part 64, the wire power supply copper plate A641, the wire clamping part 61, the suspension wire located between the wire clamping part 61 and the wire breakage part 62, the wire breakage part 62, and the wire power supply copper plate B642 form a circuit, and the wire power supply part 64 starts to supply power; the cross-sectional area of ​​the suspension wire located between the wire clamping part 61 and the wire breakage part 62 is the smallest in the entire circuit. According to the principle that the smaller the cross-sectional area of ​​the conductor, the greater the resistance, and Joule's law Q=I 2 Rt, the dropper wire located between the wire clamping part 61 and the wire breakage part 62 generates the most heat, causing the dropper wire at this location to soften due to heat; the wire breakage driver 6211 of the wire breakage part 62 drives the wire breakage chuck 623 to rotate to twist the dropper wire located between the wire clamping part 61 and the wire breakage part 62. After twisting, the wire breakage cylinder 629 fixed on the wire mounting base 63 pushes the wire breakage part 62 away from the wire clamping part 61 to break the dropper wire, thereby completing the wire cutting operation.

[0038] In this embodiment, the wire cutting module 60 is installed on the workbench 50 and located between the conveying module 30 and the wire feeding module 40. The spool of the dropper wire is fed by the feeding module 10, the correction module 20 corrects the dropper wire, and the conveying module 30 conveys the dropper wire. After the dropper wire conveyed by the conveying module 30 reaches the predetermined length, this embodiment performs the twisting and melting cutting operation. After the cutting operation is completed, the wire feeding module 40 conveys the cut dropper wire to the next station for subsequent operations.

[0039] Using the drop wire cut in this embodiment, a frustum-shaped end is formed at the cut point, which prevents the strands from unraveling and facilitates subsequent threading.

[0040] Example 2:

[0041] Based on Example 1, referring to Figure 2 , 3 As shown, the thread-cutting clamping part 61 includes a thread-cutting clamping mounting base 611 disposed on the thread-cutting mounting base 63, a thread-cutting clamping fixing block 612 disposed on the thread-cutting clamping mounting base 611, a thread-cutting clamping movable block 613 slidably disposed on the thread-cutting clamping fixing block 612, a thread-cutting clamping support column 615 disposed on the thread-cutting clamping mounting base 611, a thread-cutting clamping connecting rod 616 rotatably connected to the thread-cutting clamping support column 615, and a thread-cutting clamping cylinder 617 disposed on the thread-cutting mounting base 63. The telescopic rod of the thread-cutting clamping cylinder 617 extends out and pushes the thread-cutting clamping part 61. One end of the thread clamping link 616 rotates around the thread clamping support column 615. The other end of the thread clamping link 616 presses against the thread clamping movable block 613 so that it slides toward the thread clamping fixed block 612, thereby clamping the drop wire passing between the thread clamping movable block 613 and the thread clamping fixed block 612. The telescopic rod of the thread clamping cylinder 617 retracts, and the thread clamping movable block 613 springs back to its original position to release the drop wire passing between the thread clamping movable block 613 and the thread clamping fixed block 612.

[0042] In this embodiment, the telescopic rod of the thread-cutting clamping cylinder 617 extends and pushes one end of the thread-cutting clamping connecting rod 616. The thread-cutting clamping connecting rod 616 rotates around the thread-cutting clamping support column 615. The other end of the thread-cutting clamping connecting rod 616 presses against the thread-cutting clamping movable block 613 so that it slides toward the thread-cutting clamping fixed block 612, thereby clamping the suspension wire passing between the thread-cutting clamping movable block 613 and the thread-cutting clamping fixed block 612. After the thread-cutting operation is completed, the telescopic rod of the thread-cutting clamping cylinder 617 retracts, and the thread-cutting clamping movable block 613 springs back to reset, thereby releasing the suspension wire passing between the thread-cutting clamping movable block 613 and the thread-cutting clamping fixed block 612. The suspension wire continues to be fed, and the cycle repeats to continue the next thread-cutting operation.

[0043] Furthermore, a wire-cutting clamping insulating sheet 6111 is provided between the wire-cutting clamping mounting base 611 and the wire-cutting mounting base 63. The wire-cutting clamping insulating sheet 6111 is used to isolate the current flow to the wire-cutting mounting base 63.

[0044] Furthermore, the thread-cutting clamping fixing block 612 is provided with a thread-cutting clamping guide post 618, the thread-cutting clamping movable block 613 is slidably sleeved on the thread-cutting clamping guide post 618, and a thread-cutting clamping spring 619 is sleeved on the thread-cutting clamping guide post 618, the thread-cutting clamping spring 619 being located between the thread-cutting clamping fixing block 612 and the thread-cutting clamping movable block 613.

[0045] In this embodiment, the wire cutting clamping spring 619 is used to cause the wire cutting clamping movable block 613 to spring back and reset, thereby facilitating the feeding operation before the next wire cutting operation.

[0046] Furthermore, a wire cutting clamping connecting rod 616 is provided with a wire cutting clamping insulating block 6161 at the end above the wire cutting clamping cylinder 617. The wire cutting clamping insulating block 6161 is used to isolate the current flow to the wire cutting clamping cylinder 617.

[0047] Furthermore, the end of the wire cutting clamping link 616 located above the wire cutting clamping movable block 613 is provided with a wire cutting clamping block 614, which is used to press against the wire cutting clamping movable block 613.

[0048] Example 3:

[0049] Based on Example 1 or 2, refer to Figures 4 to 6As shown, the wire cutting and twisting part 62 includes a wire cutting and twisting mounting base plate 626 slidably disposed on the wire cutting mounting seat 63, a wire cutting and twisting mounting vertical plate 625 disposed on the wire cutting and twisting mounting base plate 626, a wire cutting power supply copper plate C643 disposed on the wire cutting and twisting mounting vertical plate 625 and electrically connected to the wire cutting power supply copper plate B642, and a wire cutting and twisting clamping connecting plate 6223 rotatably connected to the wire cutting and twisting clamping cylinder 6221, rotatably connected to the wire cutting and twisting mounting vertical plate 625, and rotatably connected to the wire cutting and twisting chuck 623. The wire cutting and twisting driver 6211 is disposed on the wire cutting and twisting mounting base plate 626, the wire cutting and twisting clamping cylinder 6221 is disposed on the wire cutting and twisting mounting vertical plate 625, and the wire cutting and twisting chuck 623... The wire cutting and twisting mounting vertical plate 625 is slidably disposed in the wire cutting and twisting mounting vertical plate 625 and can rotate relative to the wire cutting and twisting mounting vertical plate 625 and is electrically connected to the wire cutting power copper plate C643. The wire cutting and twisting clamping cylinder 6221 drives the wire cutting and twisting chuck 623 to slide relative to the wire cutting and twisting mounting vertical plate 625 through the wire cutting and twisting clamping connecting plate 6223 to clamp the drop wire passing through the wire cutting and twisting chuck 623. The wire cutting and twisting driver 6211 drives the wire cutting and twisting chuck 623 to rotate relative to the wire cutting and twisting mounting vertical plate 625 to twist the drop wire located between the wire cutting pressing part 61 and the wire cutting and twisting part 62. The wire cutting and twisting break cylinder 629 pushes the wire cutting and twisting mounting base plate 626 to slide relative to the wire cutting mounting seat 63.

[0050] In this embodiment, the wire cutting and clamping cylinder 6221 drives the wire cutting chuck 623 to slide relative to the wire cutting mounting plate 625 via the wire cutting and clamping connecting plate 6223 to clamp the drop wire passing through the wire cutting chuck 623. The wire cutting driver 6211 drives the wire cutting chuck 623 to rotate relative to the wire cutting mounting plate 625 to twist the drop wire located between the wire cutting clamping part 61 and the wire cutting part 62. The wire cutting and breaking cylinder 629 pushes the wire cutting and breaking mounting base plate 626 to slide relative to the wire cutting mounting seat 63 to break the drop wire located between the wire cutting clamping part 61 and the wire cutting part 62. Because the twisting operation is performed before breaking the drop wire, the drop wire forms a frustum-shaped end at the break, thereby avoiding the phenomenon of unraveling and facilitating subsequent threading operations.

The wire cutting and twisting chuck 623 is slidably sleeved in the wire cutting power copper ring B645 and is connected to the wire cutting power copper ring A644. The wire cutting power supply copper ring B645 is electrically connected. When the wire cutting and twisting chuck 623 is driven by the wire cutting and twisting clamping cylinder 6221 to clamp the drop wire, the elastic jaws of the wire cutting and twisting chuck 623 are restricted by the wire cutting power supply copper ring B645 and pressed so that the wire cutting and twisting chuck 623 can clamp the drop wire. When the wire cutting and twisting chuck 623 is driven by the wire cutting and twisting driver 6211 to twist the drop wire, the wire cutting power supply copper ring B645 rotates with the wire cutting and twisting chuck 623 and maintains the electrical connection between the wire cutting and twisting chuck 623 and the wire cutting power supply copper ring A644.

[0053] In this embodiment, the wire cutting power supply copper ring A644 provides rotation space and rotation track for the rotation of the wire cutting power supply copper ring B645 and ensures that the current can flow smoothly to the suspension wire clamped in the wire cutting chuck 623; the wire cutting power supply copper ring B645 provides a sliding track for the sliding of the wire cutting chuck 623, a rotation track for the rotation of the wire cutting chuck 623, a pressure clamping path for the elastic jaws of the wire cutting chuck 623, and ensures that the current can flow smoothly to the suspension wire clamped in the wire cutting chuck 623.

[0054] Furthermore, the wire cutting power supply copper plate C643 and the wire cutting twisted copper ring mounting base 624 are both provided with wire cutting twisted copper ring insulating sheets 6241 between them and the wire cutting twisted mounting vertical plate 625.

[0055] Furthermore, the wire cutting power supply copper plate C643 is connected to the wire cutting break copper ring mounting base 624 via the wire cutting power supply tension rod 6431. A tension spring is sleeved on the wire cutting power supply tension rod 6431, which allows the wire cutting power supply copper ring A644 to be engaged between the wire cutting power supply copper plate C643 and the wire cutting break copper ring mounting base 624.
