Abstract
Description
Technical field
The present invention relates to a kind of hyperconductive cable make the field superconducting tape welder and use the welding method of the superconducting tape of this welder.
Background technology
Hyperconductive cable twines with superconducting tape to be made, superconducting tape is the ceramic oxide strip material that silver alloy coats, its physical property is more crisp, the width of its overall dimensions is 4.0～4.5 millimeters, thickness is 0.22～0.23 millimeter, need during welding totally, more firmly its ceramic core weldering knot with the silver alloy polishing.Because the special construction and the property of superconducting tape, existing welding method is manually welds, and speed of welding is slow, welding quality can not get guaranteeing, influenced speed and quality that hyperconductive cable is produced, especially when producing hyperconductive cable in batches, problem is more apparent outstanding.Yet, up to now, in existing disclosed documents and materials, do not find the welder of any relevant relevant superconducting tape that overcomes above-mentioned defective and the prior art of welding method thereof as yet.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and defective, a kind of welder and welding method thereof of superconducting tape are proposed, utilize this motorisation unit that the end of superconducting tape is welded, because designed device is comparatively ingenious, employed technology is comparatively rigorous, avoiding damaging band when welding makes the end of band closely and equably weld again, the end speed of welding of superconducting tape is accelerated, welding quality improves greatly, make the end welding quality of each superconducting tape obtain unification, thereby guarantee the quality of hyperconductive cable.
For reaching above-mentioned purpose, the invention provides a kind of welder of superconducting tape, it comprises:
1) positioner, it further comprises:
A. a pedestal, it is the strip aluminum soleplate of a square-section, a side of Biao Mian length direction has one to connect boss thereon, near the middle part of upper surface, one cylindric slotted hole is arranged along its length direction, above the side of cylindric slotted hole cross section, under the upper surface of boss a little slotted hole parallel with cylindric slotted hole arranged, there is a side of boss to be evenly equipped with 2～4 screws at the pedestal length direction, is evenly equipped with 2～4 little screws in addition at the opposite side of pedestal length direction;
B. a track base, for steel, parallel with described pedestal, there is being the screw corresponding positions of a side of boss to be equipped with corresponding 2～4 through holes with described pedestal length direction, and reach vertically with the screwhole spiro bonding of this side of described pedestal by bolt and closely to be connected, the upper surface of track base has a guide groove, connects the length direction of track base;
C. a longitudinal register slide block is the steel slide block of a cross section for " " shape, and the guide block that matches with described guide groove is arranged at its perpendicular piece bottom, with described pedestal corresponding site one screw that vertically connects is arranged on its transverse arm;
D. a longitudinal register bumping post comprises a screw rod that matches with screw on the described longitudinal register slide block, and a screw head is positioned at the top of screw rod, and a boss platform that is positioned at the screw rod bottom, and the diameter of boss platform is slightly less than the width of described superconducting tape;
E. a width locating piece, be one than rectangular of the high steel square-section of described base height, one along its length side flange is being arranged near described pedestal upper surface place, this side flange rides in the limit portion of upper surface of described pedestal, it highly is the part that exceeds than described base height, lateral surface at the width locating piece is evenly equipped with 4～8 holes, wherein half is little screw, second half is a small through hole, and the alternate layout of little screw with small through hole, small through hole wherein is corresponding with uniform 2～4 the little screws of the opposite side of described pedestal length direction respectively, and connect by stove bolt, little screw wherein is combined with screw, and the top of screw is pressed on the another side of described pedestal length direction;
