APPARATUS FOR ELECTRICAL MALLEABLE DRAWING OF WIRE Russian patent published in 1995 - IPC

FIELD: wire drawing. SUBSTANCE: apparatus has body-bath, one of walls of which is made in the form of electrically insulating plate, two located in the body and mounted on driving shafts tractive washers with current lead wire and located between them draw plate holder and draw plate. Body-bath has hinged lid, on which slit spraying nozzles for lubricating-cooling fluid feeding are fixed and nozzles number corresponds to number of washers. Spraying nozzle for lubricating-cooling fluid feeding is moveably and coaxially to draw plate mounted in front of it in draw plate holder. Bottoms of draw holder and bath have holes. Besides, wall of bath also has a hole. Tractive washers are mounted so, that their lower edges are located below hole in wall, shafts - over hole in wall and upper edges of washers are located below guiding holes. Current lead wire to washers is made as melted metal contact between driving shaft and body of washer. Draw plate is current conductive and has electric connection with tractive washer body, located behind draw plate. Spraying nozzle has deflecting screen. Body is provided with sampling electrical member, that is capable to be engaged with hinged lid in closed state. Apparatus is provided with additional tractive washers, draw plate holders and spraying nozzles. EFFECT: apparatus is used in wire drawing process. 6 cl, 4 dwg
