Aluminum Large pull-automatic production line for dual-income will be 9.5mm Pole 3.0-1.7mm straight pull into the finished aluminum. The entire production line and the big pull of copper is similar to close-line using double-disk income line (a single disc can also be closed line), intelligent control, automatic switching, without stopping a disk can be loading and unloading. The aircraft structure is composed of transmission boxes, water tanks, fixed-speed wheel has three major components, the aircraft caused by the pulley wheel at constant speed by the gear drive, overcoming a general heavy-duty water tank wire drawing machine at constant speed by the motor through the V-belt drive wheel, which led to Tap the turn between the fixed rate of speed-round coordination (synchronous) performance degradation shortcomings.
