METHOD FOR MAKING ARTICLE AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2002 - IPC

Abstract RU 2195382 C2

FIELD: metal working, possibly manufacture of different type articles by milling. SUBSTANCE: method comprises steps of making blank in the form of plate; placing it between rollers in such a way that lengthwise direction of plate blank and ready article itself are parallel relative to rotation axes of rollers; at placing blank between rollers introducing support for holding plate blank between shaping surfaces of rollers and providing gap between them; selecting spacing between shaping surfaces of rollers in plane of lower narrow surface of plate blank in zone of its maximum deformation less than spacing between shaping surfaces of rollers in zone of its minimum deformation; using shaping surfaces of rollers with contours corresponding to different thickness of article along its cross ad longitudinal directions; at reducing blank between rollers successively deforming plate from its maximum deformation zones to its minimum deformation zones along lengthwise direction of plate blank. Apparatus includes base, rotary levers, rollers mounted one opposite to another onto rotary levers jointly secured to base. Apparatus includes in addition elastic support. Roller has slit in which elastic support is arranged; said support is mounted at one side onto rotary lever and at other side it protrudes from slit outside surface of roller. EFFECT: lowered labor consumption, enhanced quality of article, enlarged manufacturing possibility of apparatus and method. 7 cl, 10 dwg
