The double frequency conversion small drawing machine adopts a horizontal design, which is driven by a main motor through a flat belt to the four tower pulley spindles and take-up wheels; the take-up is independently driven by a three-phase AC motor , realizing the principle of double frequency conversion synchronous stretching and winding . The copper material enters the drawing room through the pay-off rack, and is stretched through the tower wheel and the wire drawing die. During stretching, the cooling method of the wire and the mold adopts the spray method. The copper material enters the take-up reel in turn from the take-up wheel, the counting guide wheel , the tension rocker guide wheel, the thread guide wheel, and the wire winding guide wheel. The tension of the take-up is controlled by the tension swing lever to provide the deviation signal, and the take-up frequency converter is controlled by PID to realize the double-frequency synchronous take-up. The electrical control system can set the number of meters to reach the functions of automatic shutdown, emergency stop brake, disconnection brake, fault protection emergency stop, etc. according to the customer's production needs . The production speed is steplessly regulated by the wire drawing frequency converter and the take-up frequency converter. The wiring mechanism is driven by an independent motor through a polished rod. The brake system of the take-up part adopts electromagnetic brake .
