Embodiment Construction

[0019] exist figure 1 Among them, the pressure table is composed of the adjusting guide rail 1, the fixed block 2, the upper pressing block 3 and the lower pressing block 5, which provide the required pressure during the welding process. The material of the pressure table is made of high-strength alloy steel, and the joint surface of the upper pressing block 3 and the lower pressing block 5 is precisely processed, and the parallelism and perpendicularity of the surfaces are less than 5 μm / 100mm. The fixed block 2 is embedded in the adjustment guide rail 1 and can move up and down. There is a row of through holes distributed on the adjustment guide rail 1, and the figure 2 It can be seen that the fixing bolt 7 is connected with the fixing block 2 after passing through any through hole, and is fixed on the adjusting guide rail. image 3 It is a partial enlarged view of the upper pressing block and the fixed block through 8 sets of screw bolts. The upper pressing block 3 and t...

Abstract

The invention discloses a welding device for a high-temperature superconducting coating strip joint with extremely low resistance. The welding device is composed of a pressure table and a heating stable, wherein the pressure table consists of a regulating guide rail (1), a fixed block (2), an upper pressure block (3) and a lower pressure block (5); the fixed block (2) is fixedly arranged on the middle part of the regulating guide rail through a fastening bolt (7); the upper pressure block (3) is in sleeve connection to a rotating bolt (8) through the fixed block (2); the upper pressure block (3) is moved up and down along the guide rail (1) by the rotating bolt so as to rise or drop; when welding is implemented, pressure is applied to the upper pressure block (3) and the lower pressure block (5) through the bolt, so that a welded part is tightly pressed; and the lower pressure block (5) is arranged on a bracket below the upper pressure block (3), and the lower part of the lower pressure block (5) is fitted to the heating table (6). The device can be used for conveniently completing welding of the high-temperature superconducting coating strip joint, is simple in structure, and is simple and convenient to operate; and the joint has the characteristics of low resistance, high critical current, a high n value and high mechanical strength.

Description

technical field [0001] The invention relates to a low-resistance welding station for thin-strip conductors, especially a welding station for high-temperature superconducting coated strips, especially a welding station capable of making joints of high-temperature superconducting coated strips with extremely low resistance. Background technique [0002] Due to their unique zero-resistance properties, superconducting materials are of high economic value in applications such as high-field-strength magnet manufacturing and lossless current transmission. At present, low-temperature superconducting materials with relatively mature preparation technology and their application devices have been widely used in the above-mentioned fields. However, because it works in the liquid helium temperature region (4.2K) and the cost of refrigeration is high, the application of low-temperature superconducting devices is mainly concentrated in a small range such as medical imaging diagnosis MRI an...
