Abstract
The multistage tandem wire drawing apparatus according to the present invention has a heating mechanism and wire drawing units (draw benches) arranged in tandem to correspond to the respective manufacturing stages of the work, and is characterized in that a tension of the work moving between the wire drawing units is measured. The measured tension and a predetermined reference tension are compared to calculate any deviation therebetween, and, by using a movable chuck speed of a predetermined wire drawing unit as a reference, movable chuck speeds of the other wire drawing units are controlled in accordance with the calculated tension deviation. According to the present invention, the wire drawing speeds of the wire drawing units are controlled in accordance with the tension of the work between the wire drawing units so that excessive tension does not act on the work, thereby preventing damage to the work while keeping the work taut.
