Description

Technical Field

[0001] This invention belongs to the field of manufacturing and researching magnets for strip superconducting cables, and specifically relates to a device and method for winding magnets for strip superconducting cables with straight sides. Background Technology

[0002] To avoid the problem that each coil in the winding process of a strip superconducting cable magnet is basically the same during the winding process, and to avoid the problems of crossover and stacking caused by the tension damage of the coil in the straight section, which would affect the test stability of the critical current, it is necessary to provide a winding device and method for strip superconducting cable magnets with straight sides to overcome the defects in the prior art.

[0003] Since there is currently no dedicated tooling in the field of superconducting magnets, traditional winding machines can generally wind solenoids and tube coils. The wire of a coil with a regular shape is continuously subjected to tension during the winding process, and the wire arrangement position can be precisely controlled. However, there is no tension on the straight edge section of a multi-layer coil. How to wind such a multi-layer coil with precise wire arrangement so that the actual coil's external dimensions and fill rate are as close as possible to the theoretical design model becomes very important. This is a prerequisite for ensuring the realization of the required magnetic field environment. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a device and method for winding magnets in strip-shaped superconducting cables with straight edges. The aim is to solve the problem of inconsistent winding consistency across multiple coils in the winding process of strip-shaped superconducting cables, and to avoid cross-linking and layering caused by tension loss in the straight-line coils, thus affecting the stability of critical current testing. This invention solves the technical problems of insufficient tension in the straight-line sections during the precision winding of large-diameter, multi-layered coils, and the need to add a straight-line clamping mechanism without affecting cyclic winding.

[0005] This invention utilizes a top plate adjustment mechanism on a fixed plate, connected by screws and optical axis guides, to tighten and loosen coils, facilitating the sequential installation and adjustment of multiple coil frames. Multiple straight-edge clamping mechanisms are installed at different longitudinal positions along the straight edge of the fixed plate, enabling the straight-edge winding and clamping of multiple double-panel coils. Each straight-edge clamping mechanism includes a first clamping shaft connected to a rotating pressure plate. A second clamping shaft is located at one end of the rotating pressure plate. Adjusting the rotating pressure plate allows for height adjustment of different numbers of turns during winding. This enables the single-panel clamping, single-panel adjustment, and double-panel clamping processes during coil winding.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A device for winding magnets for strip-shaped superconducting cables with straight edges includes a rotating shaft, a fixed disk, a top disk adjustment mechanism, a coil frame, a clamping mounting plate, a straight edge clamping mechanism, and a wire clamping block. The fixed disk has a D-shaped hub structure. The rotating shaft is fixedly connected to the fixed disk at its center of mass. Each fixed disk has a top disk adjustment mechanism at its indexing ribs. Multiple straight edge clamping mechanisms are installed at different longitudinal positions along the straight edge of the fixed disk. The vertical quick clamps on the straight edge clamping mechanisms are equipped with a first clamping shaft, which is connected to a rotating pressure plate. One end of the rotating pressure plate has a second clamping shaft. By adjusting the rotating pressure plate, the first and second clamping shafts on the straight edge clamping mechanisms can be quickly clamped and disassembled, allowing for height adjustment of different numbers of turns during winding. This enables single-pane clamping, single-pane adjustment, and double-pane clamping during the winding process of the strip-shaped superconducting cable magnet. The number of straight edge clamping mechanisms used can be adjusted according to the required length of the straight edge of the fixed disk.

[0008] Furthermore, the fixing plate matches the coil frame and mounting holes.

[0009] Furthermore, the fixed disk and the coil frame are matched with each other by their concentric arc surfaces.

[0010] Furthermore, the top plate adjustment mechanism of the fixed plate is fixedly installed according to the arc-shaped tangent edge of the fixed plate to achieve a tight fit.

[0011] Furthermore, the top plate adjustment mechanism is connected to tension and loosening via a screw and an optical axis guide rail, which can satisfy the sequential installation and adjustment of multiple coil frames.

[0012] Furthermore, the fixed plate is fixed to the pressing mounting plate, and the straight edge pressing mechanism on the pressing mounting plate is evenly arranged in equidistant steps along the Y-axis.

[0013] Furthermore, the straight edge clamping mechanism is provided with a first clamping shaft, which enables the coil to be adjusted up and down according to the number of turns wound.

[0014] Furthermore, the first pressing shaft is connected to a rotating pressing plate, and the rotating pressing plate is connected to a second pressing shaft. Adjusting the rotating pressing plate enables the pressing of the double-panel single coil, and the adjustment of the rotating pressing plate does not affect the winding of the second coil of the double panel. The height is adjusted according to the number of turns wound.

[0015] The present invention also provides a winding method for a winding device for a strip-shaped superconducting cable magnet with straight edges, comprising the following steps:

[0016] Step 1: Position and fix the first-stage coil frame on the winding fixture fixing plate, adjust the top plate adjustment mechanism to limit its position, make the arc surface flush, align the coil frame with the mounting holes on the fixing plate, and then fix it to perform the first-stage winding work.

[0017] Step 2, Initial state: The straight edge clamping mechanism is in a relaxed state. When the first-stage coil is wound to the nth turn, the vertical quick clamp presses down, causing the first clamping shaft to press down on the first turn of the single-layer double-panel coil under the wire block; at the same time, the height of the first clamping shaft is adjusted to adjust the coil clamping height position.

[0018] Step 3: When the first-stage coil is wound, the second turn of the double-panel winding begins. Adjust the rotating pressure plate to be parallel to the coil surface so that it does not interfere with the second turn of winding. When the first-stage coil is wound to the nth turn, adjust the rotating pressure plate and the second pressing shaft to meet the pressing conditions. When rotating to the straight edge, release the second pressing shaft at the same time. Adjust in sequence until the winding is completed.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This research aims to address issues such as inconsistent winding consistency across multiple coils in the winding process of strip superconducting cable magnets, and to prevent cross-linking and layering caused by tension loss in straight sections of the coils, which in turn affects the stability of critical current testing. It also solves technical problems related to the lack of tension in straight sections during the precision winding of large-diameter, multi-layered coils, and the addition of a straight-side clamping mechanism without affecting cyclic winding.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] like Figure 1-3As shown, the present invention provides a device for winding magnets for strip-shaped superconducting cables with straight edges, including but not limited to winding coils with multiple straight edge shapes such as single straight edge, double straight edge, and four straight edges. The device includes a rotating shaft 1, a fixed disk 2, a top disk adjustment mechanism 3, a coil frame 4, a pressing mounting plate 6, a straight edge pressing mechanism 10, and a wire pressing block 11. The fixed disk 2 has a D-shaped hub structure; the fixed disk 2 is fixedly connected to the center of gravity of the rotating shaft 1. Each fixed disk 2 has a top plate adjustment mechanism 3 at its indexing ribs. The top plate adjustment mechanism 3 is connected to the tension and loosening via a screw 3.1 and an optical axis guide rail 3.2, which can meet the sequential installation and adjustment of multiple coil frames 4. The top plate adjustment mechanism 3 is fixed to the arc-shaped tang of the fixed disk 2 to achieve a tight fit. Multiple straight edge clamping mechanisms 10 are installed at different longitudinal positions along the straight edge of the fixed disk 2. The fixed disk 2 is fixed to the clamping mounting plate 6. The straight edge clamping mechanisms 10 are evenly arranged in equidistant steps along the Y-axis on the clamping mounting plate 6, which can realize the straight edge winding and clamping of multiple double-panel coil 5 strip superconducting cable magnets. The vertical quick clamp 10.1 on the clamping mechanism 10 is equipped with a first clamping shaft 10.2, which is connected to a rotating pressure plate 10.3. One end of the rotating pressure plate 10.3 is equipped with a second clamping shaft 10.4. By adjusting the rotating pressure plate 10.3, the first clamping shaft 10.2 and the second adjusting clamping shaft 10.4 of the straight edge clamping mechanism 10 can be quickly clamped and disassembled for adjustment, thereby realizing the height adjustment of different number of turns in the winding process. This enables the single-pane clamping, single-pane adjustment, and double-pane clamping processes during the winding of the strip superconducting cable magnet of the coil 5. Furthermore, the number of straight edge clamping mechanisms 10 used can be adjusted according to the required length of the straight edge of the fixed plate 2, thereby effectively controlling the winding process of the strip superconducting cable magnet on the straight edge.

[0027] The fixing plate 2 matches the coil frame 4 and the mounting holes.

[0028] The fixed disk 2 and the coil frame 4 are matched with each other by their concentric arc surfaces.

[0029] The top plate adjustment mechanism 3 of the fixed plate 2 is fixedly installed according to the arc-shaped cut edge of the fixed plate 2 to achieve a tight fit.

[0030] The fixed plate 2 is fixed to the pressing mounting plate 6, and the straight edge pressing mechanism 10 on the pressing mounting plate 6 is evenly arranged in equidistant steps along the Y axis.

[0031] The straight edge pressing mechanism 10 is provided with a first pressing shaft 10.2, which can realize the up and down adjustment of the double-panel single coil according to the number of turns wound.

[0032] The first pressing shaft 10.2 is connected to a rotating pressing plate 10.3, which is connected to a second pressing shaft 10.4. Adjusting the rotating pressing plate 10.3 allows for the pressing of a single coil on a double-panel, and the adjustment of the rotating pressing plate 10.3 does not affect the winding of the second coil on the double-panel. The height can also be adjusted according to the number of turns wound.

[0033] The present invention also includes a winding method for a winding device for a strip-shaped superconducting cable magnet with straight edges, comprising the following steps:

[0034] Step 1: Position and fix the first-stage coil frame on the winding fixture fixing plate, adjust the top plate adjustment mechanism 3 to limit its movement, make the arc surface flush, align the coil frame with the mounting holes on the fixing plate 2, and then fix it to perform the first-stage winding work.

[0035] Step 2, Initial State: The straight edge clamping mechanism 10 is in a relaxed state. When the first-stage coil is wound to the nth turn, the vertical quick clamp 10.1 presses down, causing the first clamping shaft 10.2 to press down on the first turn of the single-layer double-panel coil under the wire block. At the same time, the height of the first clamping shaft 10.2 is adjusted to adjust the coil clamping height position.

[0036] Step 3: Once the first-stage coil winding is complete, the second turn of the double-panel winding begins. Adjust the rotating pressure plate 10.3 to be parallel to the coil surface so that it does not interfere with the second turn winding. When the first-stage coil has been wound to the nth turn, adjust the rotating pressure plate 10.3 and the second pressing shaft 10.4 to meet the pressing conditions. When rotating to the straight edge, simultaneously release the second pressing shaft 10.4, and adjust sequentially until the winding is complete.

[0037] The fixed disk has multiple straight edge clamping mechanisms 10 installed at different longitudinal positions along its straight edge, which can realize the straight edge winding and clamping of multiple double-panel coils. The straight edge clamping mechanism 10 is provided with a first clamping shaft 10.2, a rotating pressure plate, and a second clamping shaft 10.4. By adjusting the rotating pressure plate, the height of different number of turns in the winding can be adjusted, realizing the work of single-panel clamping, single-panel adjustment, double-panel clamping, and multi-panel clamping adjustment during the winding process of the coil.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
