Description

Technical Field

[0001] The invention relates to the field of network cable connection, in particular to a device for automatically making multiple wire ends of a network cable. Background Art

[0002] Network cables are the main network transmission medium for communication in substations. Network cables can be seen everywhere in substations. Network cables play an indispensable role in the communication function of substations. The production quality of network cable crystal heads directly affects whether the communication of devices in the substation is normal, and affects the monitoring quality of equipment in the substation. The number of network cable crystal heads produced in new commissioning and technical transformation and overhaul substations is huge, and some employees have low ability to make network cable crystal heads. The production of network cable crystal heads takes a long time and the quality is poor, resulting in the inability of network cables to establish links normally and abnormal communication, which greatly affects the construction progress.

[0003] In the prior art, the operation of breaking network cables usually involves tools such as circular cutters, electric soldering irons, and bevels. When using circular cutters to break network cables, it is easy to cause excessive cutting, resulting in the wires inside the network cables being cut off, causing circuit breakage. At the same time, there is a risk of burns when the plastic protective layer of the inner wires is heated and broken. Therefore, in the process of breaking the network cables, there is a situation where communication abnormalities are caused due to poor production quality.

[0024] Beneficial effects:

[0025] When breaking the network cable, first break the outer protective layer of the network cable through the surface breaking mechanism. After completing the breaking of the outer protective layer, guide the multiple internal wires into the inner wire breaking mechanism through the guide seat. When the required breaking length of the inner wire is reached, turn the adjustment handle and drive the wheel rim to rotate through the telescopic adjustment rod. The rotation of the wheel rim drives the gear to rotate, so that the fixed clamp rod cooperates with the inner wire guide hole to fix and clamp the inner wire. The fixed clamp rod is raised to a certain temperature under the action of the electric heating wire. At this temperature, the plastic protective layer of the inner wire in contact with it will melt and break. The motor is started to drive the lead screw. During the rotation of the lead screw, the nut starts to move horizontally, that is, the table moves synchronously. During the movement, the heated fixed clamp rod melts the plastic protective layer where the inner wire passes, and at the same time completes the scraping, thereby exposing the internal metal wire.

[0026] Thereby, the multiple wires inside the network cable are broken synchronously, and the breaking length of each inner wire is guaranteed to be the same, which improves the breaking efficiency and ensures the breaking effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] Reference Figures 1 to 6 The present invention provides a technical solution: an automatic production device for multiple ends of a network cable, comprising a surface breaking mechanism 2, a guide seat 3, an inner breaking mechanism 4, and a driving mechanism 5 arranged in sequence along the network cable end breaking operation process in a protective shell 1, characterized in that: the surface breaking mechanism 2 is arranged at one end in the protective shell 1, and the surface breaking mechanism 2 is used to break and cut the outer protective layer of the network cable;

[0035] The guide seat 3 is fixed in the protective shell 1 and is located between the surface skin breaking mechanism 2 and the inner layer wire breaking mechanism 4, and is used for directional disassembly and transportation of multiple network cables; the inner layer wire breaking mechanism 4 is arranged in the protective shell 1 and is driven by the driving mechanism 5, and is used for wire breaking processing of the inner layer wires.

[0036] The network cable is transported inward through the surface breaking mechanism 6, and the outer protective layer of the network cable is cut and destroyed at the same time, so that the inner layer conductors wrapped by the outer protective layer are exposed. During the continuous pushing process of the surface breaking mechanism 6, the inner layer conductors are dispersed under the action of the guide seat 3 and enter the inner layer breaking mechanism 4 respectively.

[0037] When the extension length of the inner conductor reaches the required length, that is, when the protective layer of the area needs to be cut off, the adjusting handle 6 is rotated to clamp and fix the inner conductor, and the plastic protective layer of the clamping part is heated at the same time. When the preset temperature is reached to melt the surface plastic, the driving mechanism 5 is started and the surface skin breaking mechanism 2 is closed. At this time, the surface skin breaking mechanism 2 fixes the network cable by friction to prevent movement; the driving mechanism 5 drives the layer breaking mechanism 4 to move, so that the protective layer plastic is broken by tension at the heated position, and under the continuous pulling of the inner layer breaking mechanism 4, the skin of the inner conductor is completely removed, thereby completing the breaking operation of the outer protective layer and the inner protective layer of the network cable, and at the same time, the wire breaking operation is performed synchronously on multiple inner conductors, which greatly improves the efficiency of the wire skin breaking operation.

[0038] After the inner conductor skin is broken, the surface skin breaking mechanism 2 is started in reverse, so that the network cables after the skin breaking operation are completely withdrawn from the protective housing 1.

[0039] As a preferred embodiment, the surface skin breaking mechanism 2 includes a support 21, on which a wire wheel 22 is arranged, and an inlet wire tube 24 is fixedly arranged on the support 21 through a fixed guide seat 23 at the inlet end of the wire wheel 22, and an outlet wire tube 25 is fixedly arranged at the outlet end, and a knife platform 26 is also fixedly arranged on the outlet wire tube 25;

[0040] The guide wheel 22 has a built-in driver.

[0041] As a preferred embodiment, a knife avoidance groove is provided through the side of the wire outlet tube 25 opposite to the knife platform 26 .

[0042] It should be noted that the end of the network cable is fed in through the wire entry tube 24 and contacts the wire wheel 22. The wire wheel 22 starts to continuously transport and propel the network cable through friction. During the propulsion process, the outer protective layer of the network cable is cut and destroyed by the knife table 26. After the surface is destroyed, the network cable enters the inner layer wire breaking mechanism 4 under the action of the guide seat 3.

[0043] The wire that has not correctly entered the inner wire breaking mechanism 4 under the action of the guide seat 3 can be manually adjusted so that it can accurately enter the inner wire breaking mechanism 4.

[0044] As a preferred embodiment, the tool platform 26 includes:

[0045] A base 261 is fixedly disposed on the support 21, and a sliding hole is opened on the base 261;

[0046] The skin-breaking knife 263 is slidably disposed in the sliding hole, and a compression spring 264 is fixedly disposed between the skin-breaking knife 263 and the base 261 .

[0047] It should be explained that when the outer protective layer of the network cable passes through the conductor tube 25, the epidermis can be cut by the skin-breaking knife 263, thereby completing the breaking operation.

[0048] The arrangement of the compression spring 264 enables the skin-breaking knife 263 to apply a certain pressure to the outer protective layer of the network cable, thereby ensuring the skin-breaking knife 263 has an effect of breaking the outer protective layer.

[0049] As a preferred embodiment, the guide seat 3 includes:

[0050] A fixing ring 31 is fixedly arranged in the protective housing 1, and a plurality of guide rails 32 are evenly arranged around the axis of the fixing ring 31, and the guide rails 32 are used for disassembling and transporting the network cables in a directional manner;

[0051] The unpacking guide platform 33 has one end coaxially fixedly disposed on the fixing ring 31 , and the other end is provided with a conical guide surface; a guide groove is provided on the unpacking guide platform 33 corresponding to the guide rail 32 .

[0052] As a preferred embodiment, a rotation groove is coaxially opened on one side of the fixing ring 31 close to the inner layer wire breaking mechanism 4, an adjustment handle 6 is rotatably arranged through the rotation groove, one end of a telescopic adjustment rod is fixedly arranged on the adjustment handle 6, and the other end of the telescopic adjustment rod is connected to the inner layer wire breaking mechanism 4.

[0053] It should be noted that the mesh wires with the outer protective layer broken will gradually disperse during the contact process with the guide slide groove, and gradually enter the guide rail 32 through the unpacking guide platform 33.

[0054] As a preferred embodiment, the inner layer wire breaking mechanism 4 comprises a truncated table 41, and an inner wire guide hole 44 is formed through the axial center of the truncated table 41 corresponding to the guide rail 32;

[0055] Two nuts 42 are symmetrically fixedly arranged on both sides of the truncated platform 41 and connected to the driving mechanism 5;

[0056] A wheel 43 is rotatably disposed in the round table 41 and connected to the telescopic adjustment rod;

[0057] A plurality of gears 45 are rotatably arranged in the truncated table 41 corresponding to the number of the inner wire guide holes 44 and meshed with the wheel rim 43 ; and a fixed clamp rod 46 has one end fixed on the axis of the gear 45 and the other end extending into the inner wire guide hole 44 .

[0058] As a preferred embodiment, a torsion spring is provided at the rotation connection of the gear 45 ; and an electric heating wire is provided in the fixing clamp rod 46 .

[0059] It should be noted that when the required breaking length of the inner conductor is reached, the adjusting handle 6 is rotated and the wheel rim 43 is driven to rotate through the telescopic adjusting rod. The rotation of the wheel rim 43 drives the gear 45 to rotate, so that the fixed clamping rod 46 cooperates with the inner wire guide hole 44 to fix and clamp the inner wire. The fixed clamping rod 46 is heated to a certain temperature under the action of the electric heating wire, and the plastic protective layer of the inner wire in contact with it will melt and break at this temperature.

[0060] As a preferred embodiment, the driving mechanism 5 includes a motor 51 , and the motor 51 is fixedly disposed in the protective housing 1 . A lead screw 52 is fixedly disposed on the output shaft of the motor 51 , and the lead screw 52 is threadedly connected to the nut 42 .

[0061] It should be noted that the starting motor 51 drives the lead screw 52, ​​and the lead screw 52 causes the nut 42 to start to move horizontally during the rotation process, that is, the table 41 moves synchronously. During the movement, the heated fixed clamp rod 46 melts the plastic protective layer where the inner wire passes, and simultaneously scrapes it away, thereby exposing the internal metal wire.

[0062] During specific implementation, the network cable is transported through the surface breaking mechanism 2 while the outer protective layer is broken. After the outer protective layer is broken, multiple inner wires enter the inner wire breaking mechanism 4 respectively under the action of the guide seat 3. When the inner wires reach the required length for the wire breaking operation, the adjustment handle 6 is turned and the driving mechanism 5 is started at the same time. Under the action of the driving mechanism 5, the inner plastic protective layer is broken, thereby exposing the metal wires.

[0063] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
