DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] Please refer to Figure 1-5 A cable welding device comprises a workbench 1, two clamping structures 19, and a moving structure 20. The moving structure 20 is located inside the workbench 1 and drives the two clamping structures 19 to move. A lower mold 2 is fixedly installed in the middle of the upper surface of the workbench 1, and a cooling ring 3 is fixedly installed on the left and right surfaces of the lower mold 2. A first nozzle 4 is opened on the upper inner wall of the cooling ring 3, and a through hole 5 is fixedly installed on the lower inner wall of the cooling ring 3. A return water pipe 6 is externally connected to the lower surface of the cooling ring 3, and a water supply pipe 7 is externally connected to the upper surface of the cooling ring 3. A mounting plate 8 is fixedly installed on the upper surface of the workbench 1, a water tank 9 is fixedly installed on the upper surface of the mounting plate 8, a refrigerator 10 is fixedly connected to the upper surface of the water tank 9, and a pumper 11 is fixedly installed on the lower surface of the mounting plate 8.

[0022] Specifically: The design clamps the cable surface through two clamping structures 19. The adjustable clamping structure 19 can clamp cables of different specifications. The movable structure 20 allows the two clamping structures 19 to move toward and away from each other. Through the setting of the return pipe 6 and the water supply pipe 7, the connection between the cable and the copper wire is protected to avoid the circulation of the cable insulation skin. At the same time, the recyclable design can save resources.

[0023] In this embodiment: the interior of the return water pipe 6 is interconnected with the interior of the cooling ring 3, the interior of the water supply pipe 7 is interconnected with the interior of the water tank 9, the interior of the return water pipe 6 is interconnected with the interior of the water tank 9 through the pumping device 11, and the interior of the pumping device 11 is interconnected with the interior of the water tank 9.

[0024] Specifically, the pump 11 extracts the internal cooling water and delivers it to the inside of the cooling ring 3 through the water delivery pipe 7 , and then delivers it to the inside of the water tank 9 again through the return pipe 6 .

[0025] In this embodiment: the inner wall of the lower mold 2 is provided with a lower iron sheet, and the lower iron sheet is electrically connected to the heating structure 16 .

[0026] Specifically: the heating structure 16 heats the iron sheet, thereby heating the copper wire connection and the acid-free solder, thereby preheating the copper wire surface to facilitate subsequent processes.

[0027] Working principle: During the use of the utility model, after the staff completes the advance preparation work, they start to weld it. During the welding process, the refrigerant cools the water inside the water tank 9, and the water supply pipe 7 transports the cooled cooling water to the inside of the cooling ring 3. When the cooling water enters the inside of the cooling ring 3, it will first cool the surface of the cable, and then the cooling water will be sprayed to the copper wire inside the cable through the first nozzle 4. The cooling water flows into the internal copper wire of the cable, thereby cooling the cable surface and the copper wire. The cooled water falls along the inner wall of the cooling ring 3 through the through hole 5 to the lower part of the cooling ring 3. When the cooling water accumulates to a certain extent, the pump 11 is started at this time, and the water at the bottom of the cooling ring 3 is extracted and transported to the inside of the water tank 9 through the return pipe 6. The refrigerant cools it again, thereby completing the circulating cooling. Compared with the relevant technology, the cable welding equipment provided by the utility model has the following beneficial effects: the design can achieve the effect of cooling the connection point between the wire and the sheath, avoiding the deformation of the sheath due to the high temperature of the cable during welding, and even burning the cable.

[0028] Embodiment 2:

[0029] Please refer to Figure 1-5 A telescopic rod 12 is fixedly installed on the lower surface of the mounting plate 8, an upper mold 13 is fixedly installed on the lower end of the telescopic rod 12, a circular groove 14 is opened on the lower surface of the upper mold 13, an upper iron sheet 15 is fixedly installed on the inner wall of the circular groove 14, a heating structure 16 is fixedly installed on the upper surface of the upper mold 13, a second nozzle 17 is fixedly installed on the upper inner wall of the circular groove 14, a liquid infusion tube 18 is fixedly installed on the lower surface of the mounting plate 8, and a welding liquid tank 21 is fixedly installed on the upper surface of the mounting plate 8.

[0030] Specifically: the staff only needs to clamp the cable that has been pre-coated with acid-free flux through the clamping device, and then they can realize the subsequent automatic welding. Manual welding is required. After welding is completed, it only needs to be installed into the insulating leather cover again before it can be used.

[0031] In this embodiment: the upper iron sheet 15 is electrically connected to the heating structure 16, the interior of the second nozzle 17 is connected to the interior of the welding liquid tank 21 through the infusion tube 18, and the infusion tube 18 is made of high temperature resistant material.

[0032] Working principle: When the cable needs to be welded, the staff will cut off the insulation of the cable in advance to expose the copper wire. Then the staff will evenly apply acid-free flux to the terminal. After completion, the staff will place the cable on the clamping structure 19. At this time, the two clamping structures 19 clamp the cable to be welded. After the clamping is completed, the moving structure 20 starts to drive the cable to move toward each other until the cable completely enters the inner wall of the circular groove 14 of the lower mold 2. After the cable insulation contacts the surface of the cooling ring 3, it stops moving. At this time, the telescopic rod 12 starts to drive The upper mold 13 is fitted to the lower mold 2. When the upper mold 13 and the lower mold 2 are completely fitted, the heating structure 16 is started to heat the iron sheet, thereby heating the cable connection point and the acid-free flux applied thereon. After the heating is completed, the infusion tube 18 injects the welding liquid inside the welding liquid tank 21 into the upper mold 13 and the lower mold 2 for welding. Compared with the related art, the cable welding equipment provided by the utility model has the following beneficial effects: the design can achieve the effect of automatic welding of wires without manual welding, saving time and improving work efficiency.

[0033] The pump 11 and the heating structure 16 are existing structures, and the control circuit can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field. They are only used without modification, so the control method and circuit connection are not described in detail.
