MANUFACTURING METHOD OF PRODUCTS OF TYPE STEPPED SHAFT BY CROSS-WEDGE ROLLING

摘要

FIELD: metallurgy.;SUBSTANCE: it is implemented shaping of barstock by means of redistribution of metal lengthways the axis of blank by means of movable across axis at least two wedge-like tools. At least to tone wedge-like tool it is applied additional reciprocative transportation on-the-mitre from 0° up to 90° to direction of its main motion with amplitude of oscillation from 0.002d up to 0.02d and frequency more than 10v/(πd), where: d - diametre of barstock, mm, v - rolling rate, mm/s.;EFFECT: fatigue strength of shafts is increased, surface smoothness of shafts is also increased, effort of operation drive of mill is reduced and power consumption is reduced.;3 dwg
