Method for machining bent inclined solenoid CCT skeleton through caulking groove brazing assembly process

Abstract

The invention discloses a method for machining a bent inclined solenoid CCT skeleton by using a caulking groove brazing assembly process, a method of radially halving the skeleton and reinforcing and assembling by using brazing is utilized to reduce the processing difficulty of the bent CCT skeleton, and comprises the following steps of: firstly, machining the bending inner diameter, the outer diameter and the bending radian of a bent semicircular cylinder according to the size of a to-be-machined bent CCT skeleton; then machining positioning obtuse-angle dovetail grooves in the contact surfaces of two bent semicircular cylinder skeletons, then assembling the two bent semicircular cylinders and performing welding and reinforcing in a brazing mode, and finally machining inclined spiral line grooves in the outer wall surfaces. The method is good in innovativeness and high in practicability, the problems that an existing CCT bent skeleton is large in machining difficulty and needs multi-layer nesting can be effectively solved, and the method has important reference significance on manufacturing of the bent CCT type magnet skeleton.

Description

technical field [0001] The invention mainly relates to the technical field of processing and manufacturing special-shaped superconducting magnet skeletons, and in particular to a method for processing and manufacturing curved oblique helical (Canted Cosine Theta, CCT) magnet skeletons. Background technique [0002] The CCT coil structure is a new type of magnet structure. Due to the light and novel structure of the CCT magnet coil, the quality of the magnetic field is superior, and the wire slot wall in the CCT slotted skeleton can effectively block the accumulation of the Lorent magnetic force between the turns of the coil, making the whole The stress on the coil is small, the mechanical performance is outstanding, the end of the coil does not need to be optimized, and it is suitable for various existing practical superconducting wires. The CCT structure can not only be made into a two-pole magnet, but also a quadrupole magnet. Pole magnets and other multi-pole magnet types...
