Embodiment Construction

[0063] The figures show by way of example an embodiment of the device according to the invention for bending rod-shaped conductor ends of a stator of an electrical machine, such as an electric motor or a generator.

[0064] figure 1 A schematic perspective view of the device 1 is shown. With the device 1 , the ends of the rod-shaped conductors 2 which have been plugged into the stator 3 with the substantially cylindrical shell-shaped stator base body 3 a are to be bent. exist figure 1 , the upper free end 2b of the rod-shaped conductor 2 is visible; but the device is used to bend the figure 1 The hidden lower free end of the rod-shaped conductor 2 (but it should be noted that the stator 3 can also be installed in the device 1 in reverse, so that the previous upper end 2b of the rod-shaped conductor 2 now becomes the lower end, these lower ends part can also be bent with device 1 at this time).

Abstract

In summary, the invention relates to an apparatus (1) for bending ends (2a), arranged in annular layers (L1-L4), of bar conductors (2) for an electrical machine that are arranged in a stator main body (3a), comprising multiple coaxially arranged coupling elements (6) with coupling recesses (7), by which the ends (2a) of the bar conductors (2) can be taken layer by layer and plastically deformed. Provided for each coupling element (6) is a driving platform (10), which can be moved in the axial direction (AR) together with the coupling element (6). The coupling element (6) belonging to a driving platform (10) can be rotated on the driving platform (10). All of the driving platforms (10) move axially on a common climbing linkage (11). Each driving platform (10) has a dedicated first driving device (8) for axially moving the driving platform (10) and a dedicated second driving device (9) for rotating the coupling element (6) on the driving platform (10), wherein the two driving devices (8, 9) are moved axially, together with the driving platform (10). The apparatus (1) is of a simple construction and requires little installation space.

Description

technical field [0001] The invention relates to a device for bending the ends of a straight or bent rod-shaped conductor arranged in at least four annular layers of a stator of an electric machine, in particular an electric motor or a generator, [0002] The device comprises a holder for the stator, in particular a clamping holder, [0003] The device comprises at least four coupling bodies arranged concentrically with respect to the central axis, and each of the coupling bodies has a plurality of annularly arranged coupling recesses on the front end, which are used to scarf the ends of the rod-shaped conductors of each annular layer, [0004] And the device has a first driver for moving the coupling body along the axial direction of the central axis and a second driver for rotating the coupling body around the central axis for each coupling body, so that all coupling bodies are Able to move and rotate in the axial direction independently of each other.
