LINE FOR MAKING BIMETALLIC WIRE Russian patent published in 1997 - IPC

FIELD: plastic metal working, namely manufacture of bimetallic wire. SUBSTANCE: line includes uncoiling apparatus for strip material, apparatus for forming sheath and drawing bench. Said apparatus for forming sheath has arranged successively: disc shears for slitting, multirow stand for shaping H-shaped profile and drawing dies for bending up edges. Said drawing bench includes stands for forming round blank, compensating accumulator, drawing dies for sizing said round blank and multirow coiling apparatuses. Said drawing dies for sizing round blank are mounted with possibility of cross motion for providing wire coiling in rows. Mechanism for butt welding of strip material and additional compensating accumulator are arranged between said uncoiling apparatus and disc shears. Such line allows to produce bimetallic wire of bimetallic strip material such as steel copper coated strip at slitting the last by a large number of rectangular cross section wires with copper coat on their two faces for subsequently shaping round bimetallic wire. EFFECT: enhanced efficiency. 3 cl, 5 dwg
