Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a cable welding device. Background Technology

[0002] In power transmission and other fields, standard copper and aluminum cables with dimensions of 95-300 square millimeters are widely used, and the quality of their fusion splices is crucial to the stable operation of the power system. Currently, among traditional cable splicing methods, crimping is widely used due to its ease of operation, but this method has significant drawbacks. During crimping, because the metal surfaces cannot be completely tightly bonded, excessive interfacial resistance is generated. When current passes through the cable splice, a large amount of electrical energy is converted into heat energy due to resistance, causing the cable splice to overheat. As operating time increases, heat accumulates, not only accelerating the aging of the cable insulation layer but also potentially causing serious accidents such as fires or even explosions, severely threatening the safe and stable operation of the power system. Using fusion splicing to connect cables can effectively solve these problems.

[0003] A utility model patent with authorization announcement number CN222996015U discloses a welding device for intermediate joints of power cables, including an electromagnetic induction heating machine, a melting cup, and at least one set of welding molds; the electromagnetic induction heating machine includes an electromagnetic induction heating source and a heating coil; the melting cup includes a crucible, and a blocking mechanism with an openable and closed sealing structure is provided at the discharge port at the bottom of the crucible; the welding mold includes a pair of half-open molds, and the molds are arranged in a transversely connected sequence of a positioning cavity A, a welding cavity, and a positioning cavity B, with a feeding channel connected upward in the middle of the welding cavity, and a receiving positioning port connected at the upper end of the feeding channel.

[0004] In the above technical solution, the heating machine and mold are separate structures. When welding, the molten material needs to be melted first, and then the molten material cup is connected to the welding mold. In this case, the mold temperature is low, and cold shut phenomenon is likely to occur during casting, which affects the welding quality of the cable. At the same time, the casting is achieved by manually lifting the flow blocking rod, which poses certain safety hazards. Utility Model Content

[0044] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0045] like Figures 1-7 As shown, the cable splicing device of this utility model includes a heating mechanism 1, a crucible 2, a mold 3, a first driving component 4, a base 5, a second driving component 6, a guiding mechanism 7, and a limiting block 8.

[0046] like Figures 1-5 As shown, a crucible 2 is provided at the end of the heating mechanism 1; a mold 3 is provided corresponding to the crucible 2; a first driving member 4 is fixed relative to the mold 3, and the first driving member 4 is used to drive the heating mechanism 1 and the crucible 2 to move so that the crucible 2 heats the mold 3, and the mold 3 opens the crucible 2.

[0047] As described above, the heating mechanism 1 uses an eddy current heater, which heats the molten material in the crucible 2 by eddy current heating or high-frequency electric heating, so that the molten material melts.

[0048] Mold 3 is used to insert cables, thereby positioning the two cables;

[0049] When the heating mechanism 1 heats the molten material, the first driving component 4 drives the heating mechanism 1 and the crucible 2 to move synchronously, so that the crucible 2 is close to the mold 3, and the heat generated by heating can be used to heat the mold 3.

[0050] After the molten material melts, the first driving component 4 continues to drive the heating mechanism 1 and the crucible 2 to move until the crucible 2 docks with the mold 3. The crucible 2 opens automatically, and the molten material enters the mold 3 to achieve the end welding of the two cables.

[0051] In this way, the heat of the crucible 2 is used to heat the mold 3, which ensures that the mold 3 has a suitable casting temperature, thereby effectively avoiding the occurrence of cold shut-off and helping to ensure the welding quality.

[0052] Specifically, the crucible 2 adopts a double-layer structure, with an inner graphite crucible and an outer quartz jacket. The coils of the heating mechanism 1 are arranged around the periphery of the quartz jacket.

[0053] like Figure 6 and Figure 7 As shown, the crucible 2 has a flow channel 201 inside, and the flow channel 201 is sealed by a conical sealing block 21; the mold 3 has a casting hole 301 and a through hole 302. The casting hole 301 corresponds to the flow channel 201, and a supporting part 31 is provided at the casting hole 301. The through hole 302 is connected to the casting hole 301 and is used to insert a cable.

[0054] As described above, crucible 2 is provided with flow channel 201 for outputting molten material;

[0055] The mold 3 has two through holes 302 for inserting two cables. The mold 3 also has a casting hole 301 for feeding the molten material into the crucible 2.

[0056] As the crucible 2 moves toward the mold 3, the supporting part 31 at the casting hole 301 of the mold 3 will be inserted into the flow channel 201 of the crucible 2, thereby opening the conical sealing block 21. In this way, the molten material can be automatically injected into the mold 3 to realize automated casting work, which effectively improves the convenience of operation and reduces safety hazards.

[0057] like Figure 4As shown, the first driving component 4 includes a motor 41, a lead screw 42, a connecting plate 43, and a guide 44. The motor 41 is fixed relative to the crucible 2; the lead screw 42 is connected to the movable end of the motor 41; the connecting plate 43 is connected to the heating mechanism 1, and the connecting plate 43 and the lead screw 42 are connected by a threaded connection; the guide 44 is used to guide the displacement of the heating mechanism 1.

[0058] As described above, when the first driving member 4 is working, the motor 41 drives the lead screw 42 to move. Since the lead screw 42 is connected to the connecting plate 43 on the heating mechanism 1 by screw thread, and the heating mechanism 1 is guided by the guide member 44, the heating mechanism 1 and the crucible 2 can move synchronously as the lead screw 42 rotates. This allows the crucible 2 to selectively move closer to or further away from the mold 3, so as to facilitate the addition of molten material into the crucible 2 or the injection of molten material into the mold 3.

[0059] Specifically, the guide member 44 is a guide shaft, which is fixed relative to the motor 41 and slides in cooperation with the heating mechanism 1.

[0060] like Figure 2 and Figure 7 As shown, the mold 3 includes two half molds 32, wherein the first driving member 4 and the second driving member 6 are both mounted on the base 5; one half mold 32 is mounted on the movable end of the second driving member 6, and the other half mold 32 is fixed relative to the base 5.

[0061] As described above, the base 5 serves as the mounting foundation for integrating the various components;

[0062] The mold 3 is composed of two half molds 32, and one half mold 32 is connected to the movable end of the second driving component 6. In this way, after the casting and welding of the cable is completed, the second driving component 6 can drive one half mold 32 to separate, realize automatic mold opening, and facilitate the removal of the welded cable.

[0063] Specifically, the second drive component 6 is a lead screw linear module.

[0064] like Figure 2 As shown, the guiding mechanism 7 includes a guide frame 71, guide wheels 72 and a connecting block 73. The guide frame 71 is connected to the base 5, and the guide wheels 72 are provided on the parts of the guide frame 71 located on both sides of the mold 3. The connecting block 73 is connected to the guide frame 71 and the base 5 by bolts. The half mold 32, which is fixed relative to the base 5, is provided on the connecting block 73.

[0065] As described above, the guide mechanism 7 is used to guide the cable;

[0066] Specifically, when laying cables, the cables are supported by guide wheels 72 to facilitate insertion into the mold 3;

[0067] When the integrated guide mechanism 7 is used, the guide frame 71 is connected to the base 5, and the connecting block 73 is connected to the guide frame 71 for mounting one half mold 32. The second drive member 6 is set on the base 5 for mounting the other half mold 32.

[0068] During integration, the base 5, guide frame 71 and connecting block 73 are connected and fixed with bolts to ensure ease of integration.

[0069] like Figure 2 As shown, the guide mechanism 7 also includes an adjusting rod 74 and a pressure roller 75, wherein the adjusting rod 74 is slidably engaged with the guide frame 71; the pressure roller 75 is disposed at the end of the adjusting rod 74 and corresponds to the guide roller 72;

[0070] As described above, an adjusting rod 74 and a pressure roller 75 are provided to further ensure the stability of the cable position;

[0071] When laying the cable, the cable is supported by the guide wheel 72, and then the pressure wheel 75 is moved by the adjusting rod 74, and the cable is pressed by the pressure wheel 75, thus ensuring that the cable position is fixed. This helps to ensure accurate connection of the two cables and improve the welding accuracy.

[0072] In some embodiments, the pressure roller 75 is rotatably engaged with the adjusting rod 74, and the adjusting rod 74 is threadedly connected to the guide frame 71. Thus, the cable can be pressed tightly by rotating the adjusting rod 74 through the pressure roller 75.

[0073] In some embodiments, the pressure roller 75 is not provided, and the cable is held directly by the end of the adjusting rod 74.

[0074] like Figure 4 and Figure 7 As shown, there are two limiting blocks 8. One limiting block 8 is located on the movable end of the second driving member 6 and abuts against one half mold 32. The other limiting block 8 is located on the connecting block 73 and abuts against the other half mold 32.

[0075] As described above, in order to further ensure the installation accuracy of the half mold 32, a limiting block 8 is provided on the movable end of the second driving component 6 and on the connecting block 73. In this way, the half mold 32 can be held in place by the limiting block 8, thereby ensuring the accurate installation position of the two half molds 32 and helping to ensure the subsequent docking accuracy of the two half molds 32.

[0076] Specific implementation steps

[0077] S1. Insert the two cables into the guide mechanism 7, and insert the ends of the cables into the through holes 302 of the mold 3. The cables are clamped and fixed by the guide wheel 72 and the pressure wheel 75.
