COILING APPARATUS FOR DRAWING BENCH Russian patent published in 1997 - IPC

FIELD: wire drawing equipment. SUBSTANCE: coiling apparatus for drawing bench includes frame, driven reel rigidly mounted on cantilever shaft, horizontal rollers and vertical cylinders for lengthwise orienting wire, vertical cylinders for laying wire mounted on cross carriage performing reciprocation motion and kinematically connected with drive unit by means of crank and rocking bar. Said shaft is provided with members for securing reel to it and for matching its mean plane with vertical plane of wire. Said reel has stems for gripping leading end of rolled piece and opening for fixing wire end after termination of coiling, device for preventing fluffing up, barrel- and seat-type coiling, electromechanical device for arresting drive unit at wire tearing off or after coiling it. Said drive unit of intermittent friction type provides forced rotation of reel in the result of intermittent pushing friction contact of elastic fingers mounted in drive unit with possibility of controlling effort of their pressing to drive flywheel by means of adjusting member. Said rollers and cylinders mounted with use of pins may be changed to different-diameter ones for adjusting gaps between them in dependance upon wire thickness. EFFECT: enhanced reliability and simplified design of coiling apparatus. 10 cl, 2 dwg
