Due to zero resistance, the high current density characteristic of superconductor, can be by greatly on the least superconductor cross section Electric current, the most secondary high-temperature superconducting coating band has very thin thickness, generally about 0.1mm.This Utility model, mainly for the feature of its strip, can more easily make band joint in uniform thickness, meanwhile, This utility model device is equally applicable to conventional strip conductor.
Utility model content
It is a key technology in high-temperature superconducting device research and development that joint makes, and the joint completed must have There are good electrically and mechanically performance, i.e. low resistance, high critical current, high n-value and high mechanical properties. The purpose of this utility model is to provide one and has the most low-resistance high-temperature superconducting coating band weld dress Put, make it effectively to realize the extremely low resistance characteristic of welding point, can guarantee that simultaneously joint high critical current, High n-value and the good electrical of high mechanical properties and mechanical performance.
This utility model solves its technical problem and be the technical scheme is that
One has the most low-resistance high-temperature superconducting coating band weld device, it is characterised in that welding Device is made up of pressure platform and warm table: regulation guide rail 1, fixed block 2, upper holder block 3 form pressure with lower lock block 5 Power platform, fixed block 2 is fixed in the middle part of regulation guide rail by fastening bolt 7, and upper holder block 3 and fixed block 2 are by rotation Dynamic bolt 8 associating, and by turn bolt 8 by upper holder block 3 along guide rail 1 move up and down and be raised and lowered with By turn bolt, downward for upper holder block 3 briquetting 5 is pressed and tight pressing welded piece when implementing welding;Under press Block 5 is placed in the underface of upper holder block 3, fits with warm table 6 in its underpart.
Further, described upper holder block 3 uses following structure with fixed block 2 by turn bolt 8 associating: rotation The top of dynamic bolt 8 is the thread segment 801 coupled with fixed block 2, and its underpart has flange 802;Upper holder block 3 Having inside groove 301, the groove width of inside groove is less than flange 802 diameter, and inside groove has not less than flange 802 diameter Termination 302.
During installation, after the termination 302 of upper holder block 3 is placed in below the flange 802 of turn bolt 8, by upper holder block 3 Translation, makes the flange 802 of turn bolt 8 be placed in the inside groove 301 of upper holder block 3 all the time, and such turn bolt 8 is i.e. Upper holder block 3 can be driven to synchronize to move up and down.
During actual welding operation, start heating, preset welding temperature, control upper holder block and put down and platform surface Fit together, in order to upper lower lock block can be heated simultaneously.After temperature reaches preset value, turn bolt makes Upper lower lock block temperature is maintained at predetermined value.
With scouring pad, thin strip solder side is carried out grinding process, in order to remove surface impurity and oxide layer, fall The impact of its butt joint resistance low, then clean strip surface with anhydrous alcohol.Cleaned band should enter immediately Row welding, in order to avoid secondary pollution and oxidation affect joint performance.
After jig is warming up to predetermined temperature, turn bolt 8 rises upper holder block, the two sections of bands that will process Material lies in lower lock block surface.At the band intended joint length surface appropriate scaling powder of rapid application and solder, Make solder uniformly sprawl and be distributed in its surface.Control upper holder block to put down, control apply and keep predetermined pressure, Solder is made to be full of the gap between two bands and be uniformly distributed.
Finally, it is constant that turn bolt 8 keeps joint to apply pressure, controls temperature and is at the uniform velocity reduced to room temperature, solves Except pressure, turn bolt 8 is allowed to drive on upper holder block 3 shifting, takes off the band joint welded.
The beneficial effects of the utility model are, can be readily achieved the welding between strip conductor, especially For the welding of secondary high-temperature superconducting coating thin strip joint, its joint have low resistance, high critical current, High n-value and the characteristic of high mechanical properties.Meanwhile, this utility model device is same to the welding of conventional strip conductor Sample is suitable for, and can significantly improve welding quality and efficiency, and have simple in construction, advantage easy and simple to handle.
