Abstract
1334094 Punching laminations L SCHULER GmbH 10 Dec 1971 [17 Dec 1970] 57457/71 Heading B3W A notching machine for simultaneously slotting a circular blank 48 and dividing it into a stator and a rotor lamination 36, 37 respectively has a latch 63 for positively engaging a notch 61 in, or a projection 62 on, the periphery of the blank to prevent rotation of the stator lamination 37 once it is separated from the rotor lamination 36. The blank is mounted on surface 43 on the head of a saddle stock shaft 28 by a centering mandrel 29, a key on the mandrel engaging a keyway 60 in the blank. The shaft and mandrel are indexed angularly between punching strokes in which slots 34 and dividing cuts 35 are formed, the stator lamination 36 resting on surface 44 as it is progressively separated from the blank. A wall 32 prevents lateral displacement of the laminate 36. A latch 64 is pivoted on the machine at 63 and the blank is so positioned initially that immediately before, during or after the start of the last cut the slot 61 (or projection 62) is opposite the latch which is moved, e.g. by a solenoid, into engagement with it. For engagement with the projection 62 the latch may be forked.
