FORGING-REELING MILL FOR PRODUCTION OF LARGE-DIAMETER RINGS Russian patent published in 2015 - IPC B21K1/38 B21J9/02 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and may be used for production of large-diameter rings. Detachable unit composed of vertically displacing bearing beam is arranged at the bed. Top tool to machine ring inner surface from above is fitted at said beam. Bottom tool is mounted at moving table to machine the ring outer surface from below. Detachable unit allows replacement of said top working tool outside the working position. Interchangeable sets of hammers or rollers are used as top and bottom tools. Ring driving rollers are secured at the bed for interaction with its outer surface, intermittent ring turn at processing by said set of matters and continuous revolution at machining by said set of rollers. Bottom roller is equipped with rotary drive.

EFFECT: higher machining precision, hence, decreased allowance for machining.
