Problems solved by technology

At present, in the production of 300 to 1000 core composite blanks, 300 to 1000 core composite blanks need to be assembled. Due to the small size and large number of mandrels, misalignment of the mandrels is easy to occur, making the row of mandrels irregular, resulting in Uneven arrangement of core wires caused by uneven deformation of the core wires in the subsequent processing, resulting in broken cores, core wire laps, etc., which greatly detract from the performance of the strands, affecting the performance of the wire rod and failing to meet design expectations

Abstract

The invention relates to a method for assembling a 300 to 1000-core composite superconducting blank, which is characterized in that with the adoption of a method for fixing a core rod and a round insertion rod along an outer assembly ring partition, the positions of the outer ring core rod and the round insertion rod are fixed, and the problem that the round insertion rod is easy to move is simultaneously solved. In addition, the insertion rod does not need to be supplemented after the completion of the assembly, so that the time is saved, and the efficiency is high. The 300 to 1000-core composite superconducting blank assembly method has the advantages that a special tool does not need to be used during the assembly process, so that the wire processing cost is saved. When the quantity ofcores is different, the small partition design only needs to be simply changed. The method has strong flexibility and is suitable for the small amount of contract production.
