Problems solved by technology

The tension error detected by this method is relatively large, and the tension control accuracy is not high, which affects the tightness of the inter-turn bonding of the magnet coil
[0005] The mainstream constant tension control winding equipment on the market is mainly used to control the winding of magnet coils with regular shapes (such as circular, with a fixed radius of one rotation), which cannot meet the racetrack type (the radius of one rotation changes greatly) The demand for coil winding of magnets with special shapes

[0039] The following is an example of the control method for the coil winding of the racetrack-type superconducting magnet, combined with the attached image 3 , the technical solutions of the present invention are further described in detail. Due to the particularity of the superconducting wire, in order to improve the success rate of the superconducting magnet coil winding, it is necessary to control the wire tension and the tightness of the coil during the superconducting coil winding process.

[0040] The wire tension is caused by the deformation of the wire caused by the speed difference between unwinding and winding during the coil winding process. According to Hooke's law, the tension is:

Abstract

The invention discloses an irregular superconducting magnet coil winding control device, which includes a control system, a winding and unwinding system connected with the control system, a detection system, a layer-changing mobile platform, a wire crimping device and a man-machine interface. Its control method, by keeping the difference between the winding speed and unwinding speed of the wire during the coil winding process relatively constant and the pressure of the wire pressing device acting on the wound wire constant, realizes the control of the wire tension and the coil during the superconducting coil winding process. Control of fit tightness; the special constant tension control method provided by the control device can improve the success rate of coil winding of special shapes and special materials.

Description

technical field [0001] The invention relates to a winding control device and method for an irregular coil, which is used for the winding control of a constant tension magnet coil with a special shape, such as the field of winding control of a superconducting magnet. Background technique [0002] The superconducting wire is a brittle material with a flat ribbon structure. It cannot be restored to its original state after being broken, which will affect the performance index of the entire magnet. Therefore, the bending radius of the wire during the winding process of the superconducting magnet coil cannot be too small. At the same time, the tension on the wire must be suitable and constant during winding. Excessive tension may lead to internal damage or even breakage of the wire; if the tension is too small, the tight fit of the coil may not be high, and accumulation and damage may also occur, thereby reducing the overall conductivity and thermal conductivity of the magnet. ...
