Title:
DRAWING DIE DEVICE OF MULTICORE SUPERCONDUCTING WIRE
Document Type and Number:
Japanese Patent JP2005093160
Kind Code:
A
Abstract:
To provide a drawing die device of a multicore superconducting wire, allowing uniform diameter-reducing work by preventing vibration in a drawing out process of the multicore superconducting wire.
This drawing die device of a multicore superconducting wire is equipped with a box 1 with rapeseed oil 7 stored; a holder 2 installed in the box 1; a back die 3 installed in the holder 2 and having a die hole 3a, having an inside diameter nearly equal to the outside diameter of the multicore superconducting wire 4 before diameter reduction; and a wire extension die 5 installed in the holder 2 for reducing the diameter by passing the superconductive wire 4, after passing it through the back die 3.
