Abstract

1,162,666. Making commutators; punches; deforming rings. NIPPON DENSO K.K. 28 Sept., 1966 [30 March, 1966], No. 43294/66. Headings B3A, B3E and B3W. A method of making a commutator for a dynamo-electric machine includes the steps of forming a flange 2 on a tubular blank, impact extruding the blank to form inter-connected commutator segments 3, punching holes 7 in the flange, finish forming the holes, casting insulating material 12 around the inner portions of the segments and finally separating the segments. The finished holes 7<SP>1</SP> are formed in two stages, firstly by a punch (4), Fig. 6 (not shown), in a first punching device and are brought to the required shape by a punch 8, the lower end 16 of which is of the same profile as the punch (4). Lugs 11 are formed in any suitable way on the inner surface of each segment. The outer periphery of the segments are machined to remove the bridge-pieces therebetween and grooves are made between the holes 7<SP>1</SP> so that the flange 2 is separated with each segment 3 having a connecting hole 7<SP>1</SP>.
