Definitions

  • the invention relates to a method for producing a curved, disc-shaped magnetic coil, in particular for particle accelerator systems, the conductors of which have a convex-shaped outer side and a concave-shaped inner side, thus having a partially negative curvature, using the conductors on the inside of the Winding body or elements already pressing there applied conductor windings is wound and fixed in position after the winding process.
  • the invention further relates to an apparatus for performing this method.
  • a corresponding superconducting magnetic coil is e.g. B. from the literature "Fuji Electric Review", Vol. 19, No. 3, 1973, pages 112 to 118.
  • This coil which is wound from superconductors, is curved along a circular arc length with a predetermined radius and a predetermined arc (central) angle, so that it has a convex-shaped outer side and a concave-shaped inner side.
  • This magnetic coil, the conductors of which are fixed in their geometric position by struts between these sides, is intended to serve as a lifting magnet for the contact-free levitation of a vehicle along a roadway.
  • Magnets the windings of which have negative curvatures
  • winding techniques are very complex and time-consuming, especially for superconducting dipole magnets of storage rings.
  • each pressure element has a device with a pressure roller for pressing the conductor from the outside onto the concavely shaped inside and that the pressure elements are spoke-like at a point around the center of the radius of curvature thereof Inside rotatably mounted support part are attached.
  • FIGS. 1 and 2 show an apparatus for carrying out the method according to the invention in a different view.
  • Figure 3 shows another device according to the invention in Figure 1 corresponding representation. Corresponding parts in the figures are provided with the same reference numerals.
  • Winding body 2 can be seen how it can be provided, for example, for the creation of a flat dipole magnetic coil for an electron storage ring. As shown in the figure, this winding former is already provided with a partial winding 3.
  • the winding is to be created from at least one flat, in particular superconducting conductor 4, which is taken from a storage drum (not shown in the figure) and, for winding the inner contour of the winding body, via a deflection roller 5, the partial area of the winding body to be wound there or that already on it applied part winding 3 is supplied.
  • the winding body 2 which extends along a predetermined arc length b with an arc or curvature radius p, has a constant width of 2 ⁇ s.
  • the size s is the distance from the curved line b to the two concentrically curved long sides 6 and 7 of the winding core 2.
  • This constant width of the winding core extends generally over an arc length ⁇ ⁇ ⁇ ⁇ p / 180 °, where a is the measured in degrees Is center or arc angle. According to the illustrated embodiment, a should have a value of 180 °.
  • the front ends 8 and 9 of the winding core 2 are formed by semicircles with diameters of 2 ⁇ s each. The convex-shaped outer side 7 to be wound is thus connected via these semicircles to the concave-shaped inner side 6 of the winding body to be wound.
  • the outer contour of the winding body 2 thus curved and fastened on a winding table 14 is to be wound with the at least one conductor 4 quasi continuously under a relatively high winding tension and the inner contour under a greatly reduced winding tension.
  • special pressing elements 1 are provided, which run along the concave inner side 6 of the winding body and are regularly spaced from one another. By means of these elements 11, a predetermined radial contact pressure K is exerted on the respective part of the conductor 4, so that it is held immovably on the concavely shaped inside 6 of the winding body 2 or on conductor windings already applied there until the entire winding that has been created is in it Location has been fixed.
  • the winding device provided for this purpose can be seen both from the top view of FIG. 1 and from the corresponding cross section of FIG. 2.
  • a special carrier part 13 is rotatably mounted in the winding table 14 and provided with a drive 15 in the radius center M of the curved, disk-shaped winding 3 or its winding body 2.
  • This carrier part is plate-shaped. Since the individual contact elements 11 on it are spoke-like, i.e. are fastened radially outward and these elements 1 each have a roller, the plate-like support part can also be referred to as a roller plate.
  • the changing table 14 To move the conductor 4 to the positive, i.e. To wind up the convexly curved outside 7 of the winding body 2, the changing table 14 is rotated in the direction indicated by an arrow until the "stop" position shown in FIG. 1 is reached. In this position, the conductor 4 to be unwound from the supply drum lies tangentially approximately at the outermost apex S of the semicircular end piece 8 of the winding body 2.
  • the windings already wound on the winding body are also held immovably in the region of the end piece 8, which extends from the apex S to the beginning of the outside 7 of the winding body, due to the high winding tension and, if appropriate, an additionally attached clamp.
  • the pressing elements 11 to be provided for this purpose each contain a pressure roller 16 which is attached to the radially outer end of a roller arm 17.
  • the roller arms 17 are radially displaceable. They are each in a so-called free zone F, in which individual and there designated 11 'pressing elements protrude radially outwards, that is, do not come to rest against the inner contour of the winding body 2, via an adjusting device 18 on the by the conductor thickness of the last applied conductor turn reduced radial dimension set.
  • the adjusting device 18 is used for coupling to an actuator 20 in the one in FIG Angle y marked rotation range taken from the roller table 13 in the circumferential direction, released at the end of the adjustment process and pivoted back into its starting position by a tension spring 21.
  • the angle of rotation y corresponds to z. B. the between two adjacent pressing elements included arc or central angle.
  • the angle of rotation ⁇ can z. B. correspond to one or more times the arc angle between two adjacent pressing elements. In this way, a collision of the conductor with the winding in this area can be prevented and the conductor guidance at the outlet of the pressure rollers is also improved.
  • the position of the winding former or its partial winding assumed after this turning process is indicated in this figure by dashed lines denoted by 3 '.
  • the conductor turns of the winding thus created are finally fixed in their desired position in a known manner, for example with one another and glued to the winding body.
  • FIG. 3 shows a further winding device which largely corresponds to the device shown in FIG. 1.
  • This winding device differs from the device according to FIG. 1 essentially only in a changed conductor routing.
  • the conductor 4 is guided for winding the inside 6 of the winding body 2 or conductor windings of a partial winding 3 already applied there over a now centrally arranged deflection roller 27 and placed on the corresponding inner contour via the pressure roller 28 of a pressure element 29.
  • the diameter d 'of this roller is chosen to be relatively large compared to the diameter d of the pressure rollers 16 of the other pressure elements 11 and 11'.
  • the pressure elements _71 only serve to hold the conductor on the inner contour.
  • the figure also shows the progressive winding of the inner contour, wherein advantageously a counter-rotation of the winding table 14, as in the device according to FIG. 1, is no longer necessary, indicated by dashed lines in corresponding, individual positions of the roller 28 or the conductor.
  • the individual conductor positions are designated 4'a to 4'g.
  • the directions of rotation A 'and C' of the winding table 14 and the roller table 13 are reversed with respect to the corresponding directions of rotation A and C of the device according to FIG. 1.
  • all drives of the actuators can be designed both mechanically and hydraulically or pneumatically.
  • the control of all movements in the course of the winding process takes place, for. B. by an electronically controlled sequence control.
  • the motion sequences can also be controlled via program and NC controls, because interventions by changing the program are possible in a simple manner.
  • the embodiment of the winding device was based on a curved winding body 2, the central or arc angle a of which was chosen to be 180 °.
  • Magnet coils with a corresponding shape are provided in particular for storage rings of electron accelerator systems.
  • curved bobbins with smaller arc angles can also be wound in a corresponding manner.
  • so-called double disks can also advantageously be produced on a large industrial scale in a relatively simple manner by assembling them from single disks according to the assumed exemplary embodiments.
