Abstract
716,552. Cores for dynamo-electric machines. HAWK, Ltd. June 23, 1952 [May 21, 1951], No. 11846/51. Class 35 [Also in Group XXII] Stator parts 10 for an imbricated pole stator are pressed in such a manner that the length of the poles 2 is greater than the radius from which they were originally cut out. In one method of doing this, a cup-shaped pressing, Fig. 2, has its bottom cut away to leave a series of tongues 2 separated by cuts 3 at the centre. This unit is then pressed in a die 6 having an annular groove 7 by means of a punch 5 which exerts, axial pressure on the rim 1 of the cup thus forcing it radially inwards and causing the tongues to bend axially upwards. The compression of the flange part 17 towards the centre has the effect of making the axial length of the tongues greater than they would be if merely bent up, in fact, greater than the radius r. In a modification the tongues are pressed from a plane disc whose edges are turned down axially for the securement as by welding or swaging of an outer tube. It is also stated that the tongues may be stretched.
