Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coil production, in particular to a mechanical equipment and method for preparing an iron-based strip double-deck interposed coil. BACKGROUND

[0002] The iron-based strip double-deck interposed coil is a special coil structure that combines the design of iron-based strip and double-deck coil to improve the performance and stability of the coil. This coil structure includes winding tool, welding tool, impregnation tool, and assembly device, etc. The winding tool is usually a stainless steel ring used to wind the strip into a ring-shaped coil. The existing winding equipment cannot wind the strip at both ends simultaneously, resulting in low processing efficiency.

[0003] The patent CN220627516U discloses a hierarchical double-deck superconducting coil and its preparation system. The skeleton end and the internal design of the patent are continuous arc-shaped channels that realize the smooth transition of the cable, thereby realizing the winding of different width cables in the same coil double layer and completing the hierarchical double-deck coil. At the same time, it can ensure that the cable exit end of the coil double-deck is located on the same side. In the specific winding process, the winding of the single-layer coil of the first layer cable is completed first. The measurement size leaves enough joint segment cable length, and after increasing the insulation, the first layer cable is pre-bent according to the shape of the arc-shaped transition groove to match the size of the transition groove. The cable is pushed into the transition groove and fixed, and the welding tool connects the internal welding block and the external extension block through a split structure, and performs welding and fastening between the cables through bolt pre-tightening. At the same time, the welding block is made of high-purity copper block similar to the cable material, which is a stable body at low temperature to enhance the stability of the joint. Although this patent solves the above problems, it still has the problem of low processing efficiency because it cannot wind the strip at both ends simultaneously. Therefore, a mechanical equipment and method for preparing an iron-based strip double-deck interposed coil are proposed to solve the above problems. SUMMARY
