<p>A combined straight-pass wire-drawing apparatus. The apparatus comprises drawing units each consisting of a die seat device (60) and a big disk device (74) disposed on a seat (71). At least two drawing units are present, and are arranged in a straight line. A wire tension detection device is disposed between adjacent drawing units. The wire tension detection device is connected to a motor control device driving the big disk device (74). The wire tension detection device detects the tension of a wire between the adjacent drawing units. The motor control device adjusts the rotation speed of a big disk (61) according to a tension signal obtained in the detection. The apparatus enables wires to be tightly wound on each big disk (61), and matches well the drawing speeds of adjacent big disks (61).</p> |
