Abstract

885,367. Making turbines etc.; punching; milling. SVENSKA ROTOR MASKINER A.B. March 11, 1960 [March 14, 1959], No. 8632/60. Classes 83 (2), 83 (3) and 83 (4). In making a turbine &c. blade-wheel comprising a disc 10 having at least one ring of axial blades 12, a blank is cast in the form of a disc having a ring of separate axial bladeprojections 11, the disc is turned to final shape, arid the whole length of each blade is machined in a single operation by a milling cutter 13 controlled by a pattern (not shown). A blank of nodular cast-iron may be cast in a shellmould, (Fig. 3, not shown), each blade projection haying an extension 14 for securing a ring to the blade ends. The extensions 14 may be machined to cylindrical form by a hollow drill before the blade-milling operation, or they may be in the form shown, being turned on two sides 24, 26 during the machining of the blade-ends, and milled on the other two sides 16, 18 during the blade-milling operation. The blades may taper towards their free ends. The ring may be drilled for cylindrical pins 14, or perforated by a punch when the pins are as shown, the punch being formed by turning an annular projection and dividing this by milling to form pins for punching the holes.
