Description

Technical Field

[0001] The utility model relates to the technical field of superconducting wire welding, in particular to a superconducting wire welding device. Background Art

[0002] Superconducting wires have the advantages of low resistance and high current carrying capacity, and are an indispensable part of modern power transmission systems. However, the welding quality of superconducting wires directly affects their resistance and superconducting properties, which in turn affects the operating efficiency of the entire power system. At present, the common superconducting wire welding method is resistance welding using brazing. The main goal of resistance welding is to reduce the welding resistance of the welded joint and ensure the mechanical strength of the welded joint. Due to the characteristics of the superconducting wire material itself, the welding temperature of the superconducting wire is usually strictly controlled during welding. Excessive temperature will destroy the microstructure of the superconducting wire, and the performance of the superconducting wire will be attenuated. In addition, under the premise of ensuring the welding strength, the thickness of the welding layer should be reduced as much as possible to reduce the welding resistance. The commonly used welding operation method for resistance welding is manual operation using a commercial temperature-controlled electric soldering iron or a clamp-type welding device.

[0003] However, the existing commercial temperature-controlled soldering iron manually operated or clamp-type soldering devices have poor stability of the soldering part during use, the heating temperature of the soldering parts is uneven, the soldering quality depends on the operator, and the soldering quality cannot be effectively controlled.

Two longitudinal wire wheels 2 and two transverse wire wheels 3 are symmetrically arranged on the same side. When the superconducting wire passes through the guide mechanism, it first passes between the two longitudinal wire wheels 2, then passes between the two transverse wire wheels 3, between the movable clamping wheel 16 and the fixed guide wheel 17, and between the movable clamping block 19 and the support block 20, and finally enters between the movable welding block 21 and the fixed welding block 22. Similarly, when taking out, the superconducting wire can be pulled out in one direction.

[0030] Embodiment: When in use, firstly, replace different welding molds 29 according to the model and shape of the superconducting wire, install the selected welding mold 29 at the center of the contact surface between the movable welding block 21 and the fixed welding block 22, and fix the welding mold 29 by tightening the nut 28.

Ensure that there is no gap between the two after pressing.

[0031] Then, the superconducting wires to be welded are transported to the center through the guide mechanisms on both sides of the workbench 1. The superconducting wires to be welded pass through the longitudinal wire wheels 2 and the transverse wire wheels 3 on both sides in turn, and then pass through the top of the fixed guide wheel 17 and the surface of the support block 20, and finally enter the wire groove 26 on the surface of the welding mold 29, ensuring that the welding parts of the two superconducting wires can be inside the welding groove 24.

Thus, the superconducting wire is effectively fixed.

[0033] Finally, the welding temperature is adjusted to the desired range through the heater 23 arranged outside the welding groove 24, and temperature-controlled welding is performed. The welding part can be heated and welded in all directions to ensure that it is heated evenly, thereby improving the welding quality. In addition, solder can be added through the solder adding hole 25 during the welding process to avoid insufficient solder during the welding process.

[0034] After welding is completed, the driving motor 5 drives the clamping frame 8 to move upward according to the above principle. At the same time, the reset spring 14 cooperates with the limit block 13 to push the entire clamping frame 8 upward, thereby driving the movable welding block 21, the movable clamping wheel 16 and the movable clamping block 19 to move upward, loosening the welded superconducting wire so that the welded superconducting wire can be taken out from the guide mechanism on either side.
