DEVICE FOR SHAPING OF THIN-WALL AXISYMMETRICAL PARTS OF FLATTENED CONVERGING SHAPE

摘要

FIELD: metallurgy.;SUBSTANCE: in a device containing a puncheon, a cone, a support ring, extension-type sectors, a matrix, an elastic element located between the extension-type sectors and the matrix; the extension-type sectors have different conical surfaces. The inner surface has an inclination angle of a generatrix that is larger than an external one.;EFFECT: improving the quality of parts without their faceting per a pass of a press; reducing labour input.;2 dwg
