Definitions
- the invention relates to a method for producing coils in the form of a wave winding for electrical machines, in which a substantially round or polygonal coil is first produced on a winding template, which is stripped axially from the winding template, then by radial deformation by means of a molding tool to form a wave winding molded and then transferred to a transfer or drawing tool.
- the winding template 10 in the embodiment shown consists of a plate-shaped template carrier 16, on the underside of which is distributed evenly over the circumference, for. B. six or more vertically downward, z. B. bolt-shaped template parts 18 are attached. They are all on the same radius and together form the part of the template to be wound. In the exemplary embodiment shown, it can be driven in rotation by a motor 20 about the central axis of rotation 22. While the winding template 10 rotates, the coil wire - preferably a plurality of parallel wires - via a wire nozzle arranged radially next to the winding template 10 or another wire guide member 24, e.g. B. with wire guide rollers supplied.
- the outer mold part 94 has a stationary, rounded hexagonal ring 100, on which six outer mold jaws 102 are mounted, which are driven by power cylinders 104 from a radially outer, retracted position into the radial area of the transmission or Retracting tool 14 can be advanced radially.
- an annular support plate 106 is fixedly attached to the ring 100 in a horizontal position.
- game circular inner peripheral edge has a diameter that is smaller than the diameter or the transverse dimension of a coil 54 generated on the winding template 10.
- the inner mold jaws 110 can also be driven via a central shaft, in particular when the spool 54 is generated on the winding template 10 not by rotating it, but by rotating a wire nozzle 24 about the central axis 22 when the template 10 is stationary.
- the clamping device required for this can be designed correspondingly to the winding device according to W098 / 25444, because in the device proposed here the spatial relationships between the winding template 10 and the molding tool 12 are similar to the spatial relationships between the winding template and the transfer or insertion tool according to W098 / 25444.
- the clamping device used here should also be attached to the winding template 10 or the inner part 90 of the molding tool 12 in the radial region of the shaft winding.

Abstract
L'invention concerne un procédé et un dispositif destinés à la production de bobines sous la forme d'un enroulement ondulé de machines électriques. On commence par produire une bobine (54) sensiblement ronde ou polygonale sur un gabarit d'enroulement (10). Cette bobine est enlevée du gabarit d'enroulement (10) par des poussoirs (56) puis elle est transformée en un enroulement ondulé par une déformation radiale à l'aide d'un outil de formage (12) et enfin elle est transférée sur un outil de transfert ou d'insertion (14). Pour pouvoir produire des enroulements ondulés avec des moyens simples sur un petit espace et avec une cadence très rapide, l'outil de formage (12) est disposé axialement à côté du gabarit d'enroulement (10) sur son axe de rotation.
