The present invention provides a multi-degree-of-freedom conductor depositing system for tokamak toroidal field coil winding packs, belongs to the field of development of toroidal field superconducting coils for nuclear fusion. The multi-degree-of-freedom conductor depositing system is mounted on a winding table and distributed along the contour of the toroidal field coil. The optical proximity switches detect the position signals between the winding table and the bending unit and transmit them to an automatic control system. The multi-degree-of-freedom conductor depositing system is distributed in a spiral shape from the top to the bottom from the position of the bending unit along the direction of coil winding. The conductor is deposited onto the track drive mechanism of the multi-degree-of-freedom conductor depositing device, which has a bidirectional moving and rotating function. This avoids the risk of insulation rupture due to friction between the conductor and the depositing tooling during the coil winding process. It also has the advantages of simple structure, convenient operation and high reliability.

A bifilar winding system for the manufacture of poloidal field superconducting magnets for nuclear fusion includes two superconducting coil winding production lines which are symmetrically arranged, a dropping fixture, a rotary platform and a winding mold, and an automatic control system. Each of the two winding production lines includes a conductor unwinding device, a straightener, an ultrasonic cleaning machine, a sandblasting and cleaning machine, a bending machine, an inter-turn insulation taping machine. During the winding of a coil, a superconducting conductor is unwound by the conductor unwinding device under the control of the automatic control system, then straightened, ultrasonically cleaned, sandblasted and cleaned, and bent into a desired radius, then wrapped with multiple layers of insulating tape by the inter-turn insulation taping machine, and finally fixed, by the dropping fixture, precisely on the rotary platform at a correct position within a profile of the winding mold.

The present invention discloses an inter-layer transition forming machine for winding of a large-sized superconducting coil. A vertically movable forming mechanism and a horizontally movable forming mechanism are mounted on a fixing plate. When the winding of a large-sized superconducting coil performs inter-layer transition, an armored superconducting conductor is clamped by wedge clamping mechanisms with right- and left-handed threads on the vertically movable forming mechanism and the horizontally movable forming mechanism, and a reference line on the conductor is ensured to be aligned with a reference line on a forming mold. The vertically movable forming mechanism is pressed down, under the drive of a double-acting hydraulic cylinder, in a vertical direction to form inter-layer transition, and the horizontally movable forming mechanism moves in a horizontal direction according to the reduction of the vertically movable forming mechanism.

A deposition system for winding of a large-scale superconducting magnet coil. First and second conductor supports withstand the weight of a bent conductor and allow the conductor to be lowered down in spiral and be placed smoothly onto a rotary table. The rotary table bears the weight of coils, rotates according to a contour of the coil and forwarding speed of the conductor, and tracks the winding trajectory of the coil accurately, which avoids the extra stress induced onto the conductor. The conductor placed on the rotary table is reliably clamped by clamping fixtures and adjustable rod to ensure the conductors to be placed on correct radial and toroidal positions. After treated by the deposition system, the conductor is placed to a corresponding position on the rotary table smoothly and accurately to achieve a high-precision contour control of the coil.
