GAGING MACHINE Russian patent published in 1997 - IPC

FIELD: cold plastic working of metals by surface plastic deformation. SUBSTANCE: gaging machine has base, electric engine with V-belt drive and worm reducer, which are positioned on base. Chain drive is connected with slide through screw transmission. Frame is mounted on slide. Slide end faced to immovable support is provided with central opening having truncated surface. Two conical inserts are disposed within truncated cone and fixed by threaded cover with central opening. Inner surface of inserts is made in the form of semicircular channels defining central opening. Immovable support has central opening and coaxial receptacles disposed at both sides of opening. Tool casing is positioned in one receptacle. Immovable support has openings positioned in symmetry relative to central axis, two openings at each side. Guiding columns connected by cross-piece and frame are mounted in openings. To operate gaging machine, for instance, in reduction mode, tool casing is placed into coaxial receptacle positioned in immovable support at the side adjacent to slide. Guiding ejector is positioned into central opening defined by inserts and fixed by threaded cover. Workpiece is positioned in trough, which may be adjusted in vertical plane, so that its axis is aligned with tool casing. Electric engine is switched to urge pulley to rotate. Rotational motion is transmitted through V-belt drive to slide with ejector, which pushes workpiece in longitudinal direction. While passing through tool casing channel, workpiece is deformed to obtain predetermined shape and is further delivered to receiving trough. EFFECT: increased efficiency, wider operational capabilities and improved characteristics of surfaces of workpieces. 1 dwg
