Abstract

897,136. Making turbine blades; die-rolling. GENERAL ELECTRIC CO. May 26, 1959 [May 28, 1958; Oct. 9, 1958], No. 23014/61. Divided out of 897,133. Classes 83 (2) and 83 (4). Apparatus for rolling an airfoil blade blank 13 having an airfoil portion 10a joined by a transition region 10# to a base portion 10b, comprises a pair of rolls 44, 45 having corner die surfaces 44a, 45a running into arcuate die surfaces 44c, 45c, means 78, Fig. 11, for forcing the rolls together to apply metal pinching forces 49b, 49c, Fig. 7, on the transition region, means to apply simultaneously a compressive force 46a on the rear of the base 10b to urge the latter against the corner die surfaces, and after reversing this force to 51, Fig. 9, means 69 for rotating the rolls to roll from the airfoil section 10a. The apparatus is identical with that described in Specification. 897,133. Specifications 897,135 and 897,137 also are referred to.
