Abstract

The invention discloses a control device and method for the unwinding tension of cold continuous rolled thin copper strips, and belongs to the field of tension control. The control method comprises the following steps of feeding detected data back to a tension system by a pressure sensor on a tension roller and encoders on a metering roller, a left uncoiler and a right uncoiler; calculating the radii of the left roll of copper strip and the right roll of copper strip according to the linear velocity of the copper strips and the angular velocity of the left uncoiler and the right uncoiler; setting tension gradients of multiple sections according to the lengths of the copper strips by the tension system, and matching a tension gradient formula according to the copper strip operation distanceby the tension system, thereby obtaining the theoretical ideal tension required by the copper strips at the operation distance; and controlling the rotating speed and the torque of the left uncoilerand the right uncoiler to further form the difference between the left linear velocity and the right linear velocity to complete the tension regulation and control of the sections after the tension system compares the theoretical ideal tension with the real-time tension. Through the adoption of the technical scheme, the problem that in the unwinding process, the copper strips are likely to deviateis solved, and the bonding problem of layers of the copper strips is avoided.

Description

technical field [0001] The invention relates to the field of tension control, more specifically, to a device and method for uncoiling tension control of a thin copper strip after continuous cold rolling. Background technique [0002] The original unwinding machine adopts constant tension control during tension control. During the unwinding process, the tension adjustment is manually controlled, and the tension adjustment accuracy is not high according to the coil diameter. Therefore, the strip is prone to deviation and adhesion during winding. Phenomenon, affect the product pass rate. [0003] Among them, due to its own performance and the influence of its thickness, length and other dimensional factors, the deviation and adhesion of the thin copper strip are more obvious during the unwinding process. In the actual production process, the thin copper strip is stuck, The amount of scrapped copper strips caused by deviations has continued to increase, which has greatly caused...
