Problems solved by technology

[0010] In addition, this makes extrusion difficult, that is to say, it becomes difficult to encapsulate the litz wires with plastic insulation in the extrusion method.

Embodiment Construction

[0067] figure 1 The stranding machine ( 1 ) according to the invention shown in is a double-click stranding machine with a stranding device in which the rotor rotates with a rotor yoke (not shown). In the interior of the rotating volume of the rotor yoke, the housing 14 is suspended at its left end and at its right end by means of two rotor bearing housings 7 to two separate rotor shaft sections (not shown).

[0068] The first winding roller 3 is arranged on the housing 14, and this winding roller is a pulling disc at the same time; the second winding roller 4 and the reel (not shown) and winding equipment 8 are used to wind the twisted wire on the on the scroll.

[0069] exist figure 1 Among them, the first winding roller 3 and the second winding roller 4 are vertically stacked and arranged along axes parallel to each other. On the circumference of the first winding roller 3, five surrounding first winding tracks 5 parallel to each other are set 1 ,...,5 5 . On the circ...

Abstract

In a first embodiment, the invention relates to a stranding machine (1) for wires having two wrap-around rollers (3, 4) having wrap-around tracks (51,..., 55; 61,..., 64) arranged on the circumference thereof, whereby the wire (2) can be guided in such a way that the wire runs through the first and second wrap-around tracks (51,..., 55; 61,... 64) preferably in alternation in preferably 8-shaped or 0-shaped wraps. In a second embodiment, the stranding machine (1) has a winding device (8) for winding the wire (2) onto a reel having a laying device (15) that can be moved along a movement axis parallel to the reel axis and having a plurality of rotatably supported deflecting rollers (9 to 13), whereby the wire (2) can be guided in such a way that the wire runs onto and / or from each of the deflecting rollers (9 to 13) substantially in the plane of rotation of the deflecting roller. In this way, the produced wire (2) has lower twist and lower torsional stresses, which makes the further processing of the wire, in particular the winding, assembly, crimping, and extrusion of a plastic insulation around the wire easier and which increases the number of possible bending reversal cycles.

Description

technical field [0001] The entire content of the priority application DE 10 2015 001 430.7 is hereby incorporated by reference into an integral part of the present invention. [0002] The invention relates to a stranding machine for producing litz wire from a plurality of preferably metallic wires. In this stranding machine, a plurality of such wires are twisted to one another, ie processed to form a stranded wire. The wire is here preferably made of a copper alloy, particularly preferably of a copper-manganese or copper-zinc alloy, for example with a proportion of 0.2% or 0.3% of manganese or zinc, or likewise of a copper-silver alloy. Background technique [0003] Prior art stranding machines have stranding devices for stranding the wires. [0004] Preferably, the stranding device has a rotating rotor with an elongated rotor yoke that is bent radially outward and is rotatably mounted at its two ends. A plurality of wires is fed to the rotor and guided via the rotor yoke...
