Abstract

The stripping device has been designed for the formation of open type "hairpins" used in the production of rotos and stators for DC electric machines. The device ensures control over the thickness of the material removed from the surfaces of the wire with increased quality of the varnish stripping process. The varnish stripping unit consists of a movable plate (2) with a shaped cut-out whose length determines the maximum longitudinal travel of the movable plate (2); two pairs of opposite steel wire top (4) and bottom (5) brushes of equal diameter are fixed to the movable plate (2) and are able to rotate at the same peripheral speed. The outer diameters of each pair of opposite brushes (4 and 5) are located at a distance corresponding to the thickness of the wire (1) and, a belt drive (10) connected to an electric motor (11) provides the possibility of opposite rotation of each two homonymous brushes (4 and 5).
