СПОСОБ ИЗГОТОВЛЕНИЯ ПРОФИЛЬНЫХ ЗАГОТОВОК ДЛЯ ОСЕЙПОДВИЖНОГО СОСТАВА

摘要

FIELD: plastic working of metals, namely manufacture of shaped blanks of axles of undercarriage of rolling stock. ^ SUBSTANCE: method comprises steps of making rough blank from ingot; then forging rough blank for making shaped blank. Rough blank is forged during several passes. Forging operations for making rough blanks and forging operation for making shaped blank are realized in four -striker forging apparatus by squeezing at shear deformations in cross plane of blank during each single squeezing. Single squeezing stages during first three forging passes at making rough blank are realized at displacing metal between strikers and then squeezing said portions of blank in radial direction. Four-side radial squeezing operations are realized for making shaped blank. ^ EFFECT: improved efficiency of method. ^ 1 tbl, 1 ex
