METHOD OF MANDRELLING WITH STATIC PULSE LOADING Russian patent published in 2012 - IPC B24B39/00

Abstract RU 2460627 C2

FIELD: machine building.

SUBSTANCE: invention comprises lengthwise feed by applying static load to mandrel with deforming cutting elements. Note here that workpiece does not displace while mandrel is additionally driven in lengthwise in pulse mode by hydraulic cylinder. The latter accommodates striker and waveguide and allows applying static load and intermittent pulse load by striker and hydraulic cylinder feed hydraulic generator. Waveguide and striker are made up of equal-diameter rods.

EFFECT: higher efficiency, higher quality of hardening, deeper hardened layer.
