Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing, and in particular to a rapid welding device for cable processing. Background Technology
[0002] Thermofusion welding of power cables (usually referring to exothermic welding or fire-mud welding) is a process that uses the aluminothermic reaction to generate high-temperature molten metal, permanently fusing the cable conductors together. Its characteristics include molecular-level bonding, resulting in advantages such as low resistance, high mechanical strength, and corrosion resistance. It is widely used in power systems, lightning protection, and grounding applications. Thermofusion welding generates a high temperature of 2500~3000℃ through the aluminothermic reaction (an exothermic reaction between aluminum powder and metal oxides), melting the welding flux to form a liquid metal that fills the mold cavity and wraps around the conductor ends. After cooling, a molecularly bonded joint is formed.
[0003] The existing hot melt welding process requires workers to manually insert both ends of the cable to be welded into the cavity of the welding mold, which is very troublesome and difficult for a single person to complete.
[0004] Therefore, it is necessary to provide a new rapid welding device for cable processing to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a rapid welding device for cable processing, which solves the problem that the existing hot melt welding process requires workers to manually insert both ends of the cable to be welded into the cavity of the welding mold throughout the entire process, which is very troublesome and difficult for a single person to complete.
[0006] The cable processing rapid welding device provided by this utility model includes a workbench with several support legs fixed at the bottom, a welding mold placed on the workbench, a first slide groove opened on the workbench, two movable seats slidably arranged inside the first slide groove, two arc-shaped clamping blocks spaced apart on the top of the movable seats, and a second slide groove opened on the movable seats.
[0007] One of the arc-shaped clamping blocks is fixed on the movable seat, and the bottom of the other arc-shaped clamping block is fixed with a slider, and the slider is slidably connected to the second slide groove.
[0008] In a preferred embodiment, a tightening screw is movably disposed inside the second slide groove, the tightening screw passing through the slider and threadedly connected thereto.
[0009] In a preferred embodiment, one end of the tightening screw extends out of the movable seat and is equipped with a crank.
[0010] In a preferred embodiment, a rubber protective pad is fixed to the inner wall of the arc-shaped clamping block.
[0011] In a preferred embodiment, a bidirectional lead screw is movably disposed inside the first slide groove, with both ends of the bidirectional lead screw passing through the bottom of the two movable seats respectively, and the bidirectional lead screw being threadedly connected to the movable seats;
[0012] A mounting bracket is fixed to one side of the workbench, and a motor is mounted on the mounting bracket. The output end of the motor is connected to the bidirectional lead screw through a coupling.
[0013] In a preferred embodiment, both the bidirectional lead screw and the tightening lead screw are galvanized.
[0014] The beneficial effects of this utility model are:
[0015] When using this rapid welding device, the operator only needs to insert the two exposed copper cables into the corresponding two arc-shaped clamps for fixation. After fixation, the motor is started. Under the action of the bidirectional lead screw, the two moving seats drive the two copper cables closer together. At the same time, the operator can move the welding mold between the two copper cables, bringing them closer together until they are inserted into the mold cavity. Finally, clamps or bolts are used to fix the welding mold to prevent movement. At this point, the welding ball can be added for welding. The two pairs of arc-shaped clamps can align and insert the two copper cables into the mold to be welded, greatly reducing the difficulty of operation for the operator. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1A three-dimensional view of the main structure of the cable processing and rapid welding device provided by this utility model; Figure 2 for Figure 1 A magnified structural diagram of A is shown below; Figure 3 A top view of the main structure of the cable processing and rapid welding device provided by this utility model.
[0022] In the specific implementation process, such as Figures 1-3 As shown, a workbench 1 with several support legs 2 fixed to its bottom is included. A welding mold 14 is placed on the workbench 1. A first slide groove 3 is provided on the workbench 1. Two movable seats 4 are slidably arranged inside the first slide groove 3. Two arc-shaped clamping blocks 5 are spaced apart on the top of the movable seats 4. A second slide groove 6 is provided on the movable seats 4. One arc-shaped clamping block 5 is fixed to the movable seat 4, and a slider 7 is fixed to the bottom of the other arc-shaped clamping block 5. The slider 7 is slidably connected to the second slide groove 6. A tightening screw 8 is movably arranged inside the second slide groove 6. The tightening screw 8 passes through the slider 7 and is threadedly connected to it. One end of the tightening screw 8 extends out of the movable seat 4 and is equipped with a crank 9. During operation, the operator turns the crank 9 to rotate the tightening screw 8. Under the action of the tightening screw 8, one of the arc-shaped clamps 5 moves closer to the other arc-shaped clamp 5 along the second slide groove 6. A rubber protective pad 10 is fixed to the inner wall of the arc-shaped clamp 5. When fixing the cable, the rubber protective pad 10 prevents the arc-shaped clamp 5 from damaging the cable surface. It should be noted that after fixing, a certain distance needs to be maintained between the end of the cable to be welded and the arc-shaped clamp 5 (this can be adjusted according to the cable model) to ensure that the part of the cable to be welded can be completely inserted into the mold cavity of the welding mold 14. Taking a 15KC cable as an example, the cable cross-sectional area is ≤120mm². 2 When inserting the cable, the length should be approximately 50-70mm. At this time, at least 80mm of space should be reserved between the end of the cable to be welded and the arc-shaped clamp 5.
[0023] A bidirectional lead screw 11 is movably installed inside the first chute 3. The two ends of the bidirectional lead screw 11 pass through the bottom of two movable seats 4 respectively, and the bidirectional lead screw 11 is threadedly connected to the movable seats 4. A mounting frame 12 is fixed on one side of the worktable 1, and a motor 13 is installed on the mounting frame 12. The output end of the motor 13 is connected to the bidirectional lead screw 11 through a coupling. After the two copper wires of the cable are fixed by two pairs of arc-shaped clamps 5, the motor 13 is started to drive the bidirectional lead screw 11 to rotate. Under the action of the bidirectional lead screw 11, the two movable seats 4 drive the two copper wires of the cable to move closer to each other. At the same time, the operator can move the welding mold 14 between the two copper wires of the cable. The two copper wires of the cable move closer to each other until they are inserted into the mold cavity of the welding mold 14. Finally, clamps or bolts are used to fix the welding mold 14 to prevent movement. At this time, the welding pot can be added for welding work. The bidirectional lead screw 11 and the tightening lead screw 8 are both galvanized to improve their service life.
[0024] The working principle of this utility model is as follows: When using this rapid welding device, the operator can move two cables to be welded (with the last insulation layer stripped) to both ends of the workbench 1, insert the two exposed copper wires of the cables into the corresponding two arc-shaped clamps 5, and finally the operator turns the crank 9 to drive the tightening screw 8 to rotate. Under the action of the tightening screw 8, one of the arc-shaped clamps 5 moves closer to the other until the copper wire of the cable is fixed.
[0025] After the two pairs of arc-shaped clamps 5 fix the two copper wires of the cable respectively, start the motor 13 to drive the bidirectional screw 11 to rotate. Under the action of the bidirectional screw 11, the two moving seats 4 drive the two copper wires of the cable to move closer to each other. At the same time, the worker can move the welding mold 14 between the two copper wires of the cable. The two copper wires of the cable move closer to each other until they are inserted into the mold cavity of the welding mold 14. Finally, use clamps or bolts to fix the welding mold 14 to prevent movement. At this time, the welding pot can be added for welding work.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
