Abstract
912,705. Making cylinder liners; spinning. LAYSTALL ENGINEERING CO. Ltd. Jan. 4, 1960 [Jan. 5, 1959], No. 351/59. Classes 83 (2) and 83 (4). A method of forming a flange at the end of a metal sleeve 10 in e.g. the manufacture of engine cylinder liners or sleeves, consists in mounting and retaining the sleeve within a collet or hollow chuck 11 with a part 10a of the sleeve projecting therefrom and in progressively turning the projecting part outwardly with respect to the sleeve axis by applying pressure on to the inner surface of the projecting parts by a roller 12, and by rotating said sleeve relatively to the roller about the sleeve axis and at the same time turning the said roller by means of a handle 14 through a path such that the projecting part is flared outwardly to form the flange. The axis on which the roller turns bodily is selected to obtain a gradual turning so that the grain flow of the material follows the contour of the section, thus ensuring adequate strength despite the thin section. The roller axis may be mounted so as to be moved eccentrically, thus reducing the radius of turning as the outflaring progresses. Alternatively, the holder is stationary and the roller axis arranged to turn in a circular path and to be moved to provide the outflaring of the projecting end part. Specification 912,706 is referred to.
