Abstract

658,578. Making screw-cutting dies. CHARPILLOZ, D. June 1, 1949, No. 14730. Convention date, Dec. 16, 1948. [Classes 83 (ii), 83 (iii) and 83 (iv)] The tongues 3 carrying the cutting edges 8 of a single-piece screwing die have their axes inclined to radii from the die centre so that the cutting edges have relieved lands 4. Angular bending.-The tongues may be pushed laterally to give this inclination by conical mandrels 5 pressed into the clearance holes 2, with the larger bearing surface 6 supported on a rigid part of the die opposite the end of the tongue.
