Description
Technical field
The present invention relates to superconducting wire stranded cable field, specifically a kind of nuclear fusion device is with hyperconductive cable conductor stranded cable outside diameter control device and control method.
Background technology
Hyperconductive cable (CICC) pipe dress cable conductor is a kind of multistage cable; The sub-cable of the first order of conductor is made up of according to certain twisting pitch is stranded some copper cash and some superconducting wires; Then with some root cables unit again according to the sub-cable of the stranded formation secondary of certain twisting pitch; In like manner constitute three grades, the sub-cable of level Four again, final strand is processed Pyatyi utmost point cable.Superconduction strand after hyperconductive cable is stranded reaches 1154, and every superconduction strand diameter is 0.73 ± 0.003mm, is made up of many superfine superconducting filaments again.Because the void coefficient of cable external diameters at different levels, cable is bigger for the electromagnetic performance influence of conductor, therefore, CICC pipe dress cable conductor stranded cable process requires to be strict for the control of the voidage of the external diameter of cable, cable.
Because the design external diameter of CICC tubulose hyperconductive cable is much smaller than the natural external diameter of cable twisting, in cable stranded, must take the measure of external diameter undergauge, the material of superconducting filament is harder; Almost do not stretch rate, as by the way of normal cable conductor undergauge the external diameter of hyperconductive cable being controlled, the niobium coating on superconduction strand surface is very easily wiped off in undergauge; The superconduction strand that is positioned at the hyperconductive cable top layer very easily is out of shape, and the superconducting filament of strand very easily ruptures, and the voidage that is positioned at the top layer strand is littler than the voidage of nexine strand; Cause the cable voidage unbalanced; Elasticity because of superconducting filament is bigger again, behind the undergauge, and the bounce-back of superconduction strand; Cause the hyperconductive cable external diameter non-constant, the requirement that the stranded like this hyperconductive cable that goes out does not reach the hyperconductive cable technical specification at all.
Summary of the invention
The purpose of this invention is to provide a kind of nuclear fusion device with hyperconductive cable conductor stranded cable outside diameter control device.
Another object of the present invention provides a kind of hyperconductive cable conductor stranded cable outside diameter control control method, with solve hyperconductive cable strandedly press that the superconduction strand coating that exists in the outside diameter control comes off, superconducting filament fracture, the uneven problem of voidage.
The objective of the invention is to realize through following technical scheme:
A kind of nuclear fusion device is with hyperconductive cable conductor stranded cable outside diameter control device, and it comprises doubling mould, level rolling wheel set, shaping sizing mould, is provided with rolling wheel set behind the doubling mould, is provided with shaping sizing mould after the rolling wheel set, and said level rolling wheel set is at least 6 groups; Said level rolling wheel set comprises top roll last item, lower roll last item, last rolling wheel, following rolling wheel and bearing; Said going up is the roll-in hole between rolling wheel and the following rolling wheel; The roll-in hole of said level rolling wheel set is on a center line, and it is gradually little successively from doubling die end to shaping sizing die end that each organizes the aperture in roll-in hole of level rolling wheel set; Roll-in axle in the adjacent roller press nips is vertical each other to be arranged.Per two pairs of rolling wheel set are vertical each other places, and cable is stressed repeatedly at level, vertical both direction, and the strand of ectonexine is looked for position, pressurized automatically, makes that the voidage of cable all directions is consistent.
Through rolling wheel set, make stranded hyperconductive cable that a radial pressure to cable center arranged, successively decrease in each rolling wheel set aperture, road; When making cable through the per pass rolling wheel set; Evenly stressed, the external diameter of cable is ladder and progressively reduces, and the radial load of pressurized is progressively to the internal layer transmission; When having avoided normal cable to press, cable surface compressive deformation, inner stressed very little, the inside and outside inconsistent problem of voidage of cable.
As further improvement of the present invention, the pass in said roll-in hole is an ellipse.Disciform pass can guarantee that cable can be fully stressed and do not damage strand.
Further improve as of the present invention, the ratio of said roll-in hole major and minor axis is 1.3-1.6.
Doubling mould according to the invention is preferably two; The effect of twice doubling wolfram steel mould is that the superconduction cable carries out well-regulated closing up with stranded strand in stranded; The big 2-3mm of calculating external diameter of the first channel ratio cable twisting, wolfram steel mould aperture, second road equals the calculating external diameter of cable twisting.The effect of the first road wolfram steel mould is that the cable strands of strand is closed up, and this nib footpath, road can not add 2mm less than calculating external diameter, otherwise; Can cause the strand surface impaired; Can not add 3 mm greater than calculating external diameter, otherwise cause strand can not rule stranded, creek takes place to jump in strand when serious; The second road wolfram steel mould action is that the strand strand further closes up, and makes stranded strand tight to greatest extent, regularly arranged under the condition that does not sustain damage.
A kind of nuclear fusion device of the present invention is with hyperconductive cable conductor stranded cable outside diameter control method, and it is the following step:
A, at first each strand closes up through doubling mould earlier;
B, the strand that closes up carry out roll-in through at least six road rolling wheel set;
The cable of C, process roll-in gets into shaping sizing mould, and the aperture of shaping sizing mould (10) is than the little 0.2-0.5mm of external diameter of hyperconductive cable;
Said doubling mould and shaping sizing mould are divided into inlet region, deformed area, sizing area and outlet area; The angle of inlet region is 40-50 ° of angle; Inlet region length is 6-8mm, and the angle of deformed area is 30-40 ° of angle, and asynchronous region length is 8-10mm; Sizing area length is 2-3mm, and outlet area length is 1-1.5mm;
The angle of said shaping sizing mould inlet region is 40-50 ° of angle, and the length of inlet region is 3-5 mm, and the deformed area angle is 20-30 °, the length 5-8mm of deformed area, and sizing area length is 3-5 mm, outlet area length is 1-1.5mm.Main because superconducting filament has rebound phenomena, effect is the roundness that further improves hyperconductive cable after the roll-in, makes the external diameter uniformity of hyperconductive cable to meet the external diameter tolerance.
Hyperconductive cable external diameter of the present invention is constant, and the stranded hyperconductive cable that goes out can reach the requirement of hyperconductive cable technical specification.
