APPARATUS FOR DRAWING WIRE Russian patent published in 2004 - IPC

FIELD: wire drawing production. SUBSTANCE: apparatus includes housing, drawing die holder mounted in housing with possibility of rotation from drive unit, drawing die, unit for supplying technological lubricant and drawing drum. Drawing die holder is in the form of sleeve with axial duct communicated with nipple for supplying technological lubricant. Inner race is secured to sleeve and concentrically relative to it outer race is mounted in housing; both races have raceways for balls arranged in retainer between said races. Inner race has radial opening for placing piston spring-loaded to outside and protruding over raceway with possibility of engaging with balls. Under-piston cavity of radial opening is communicated with passage of sleeve. At end of sleeve duct ram with axial opening for wire is arranged; drawing die mounted on said ram is spring-loaded opposite relative to direction of feeding wire. Drawing drum may have variable radius. Invention provides rotation, lengthwise reciprocation motion of drawing die and lengthwise oscillations of wire relative to drawing die. EFFECT: lowered friction force at wire drawing process. 2 cl, 2 dwg
