METHOD OF MAKING PARTS LIKE HOLLOW SOLIDS OF REVOLUTION WITH STIFFNESS VARYING IN CROSS-SECTION

摘要

FIELD: process engineering.SUBSTANCE: invention relates to metal forming, particularly to making parts like hollow solids of revolution with stiffness varying in cross-section. Rolled normal grade carbon steel blank is cut to produce welded cylindrical shell. Made shell ends are machined and subjected to local heat-treatment. Variable-stiffness elements are forged to ring ribs at shell ends.EFFECT: lower labour and material input.6 cl, 4 dwg, 2 ex
