Embodiment Construction

[0012] As shown in Figure 2, the tension measuring roller 4 is fixed on the oil cylinder base 1 with lifting function, and the tension measuring roller 4 is located between the fixed roller 2 and the upper anti-wrinkle roller 3 of the hydraulic shear. When the cold-rolled strip 5 is threaded, the tension measuring roller 4 is lower than the steel strip, and the upper anti-crease roller 3 is higher than the position of the steel strip at the same time, that is, the tension measurement roller 4 and the upper anti-crease roller 3 are not in contact with the steel strip. After the belt threading is finished, the tension measuring roller 4 rises to the limit position under the action of the oil cylinder, and at the same time, the upper anti-wrinkle roller 3 rises to the limit position under the action of the oil cylinder. At this moment, the steel strip is in surface contact with the fixed roll 2, the tension roll 4 and the upper anti-wrinkle roll 3, and the cold-rolled strip 5 on t...

Abstract

The invention relates to a cold rolling production line upper plate aligning device, in particular to an online tension detection mechanism. The invention is characterized in that the invention comprises at least one tension detection mechanism; a tension detection roller (4) is fixed on an oil cylinder base (1) with lifting function; the tension detection roller (4) is arranged between a hydraulic shear and an upper crease-resist roller (3), leading a cold rolling plate strip (5) on the upper surface of the tension detection roller (4) to the hydraulic shear at the front end and form an angle with the upper crease-resist roller (3) on the rear surface when the cold rolling plate strip (5) passes through a fixed roller (2), the tension detection roller (4) and the upper crease-resist roller (3); the lower surface of the tension detection roller (4) forming the angle is provided with a tension sensor (6) which is connected with a detection circuit; the value of the horizontal distance between the fixed roller (2), the tension detection roller (4) and the upper crease-resist roller (3) is fixed. The invention has the advantages of simple structure, safe and reliable performance, being used for direct tension closed loop control.

Description

technical field [0001] The invention relates to a flat shape alignment device on the working line of a cold rolling mill, in particular to an on-line tension detection mechanism. Background technique [0002] The requirements for the shape of the plate are getting higher and higher on the operation line of the cold rolling mill. The existing solution is to carry out tension rolling on the strip during the rolling process. While the tension is given, the torque of the motor is calculated through the current of the motor, and then the relative tension on the belt at this moment is obtained. This indirect method realizes the relative value tension control, and the relative control precision is low. Contents of the invention [0003] The object of the present invention is to provide an online tension detection mechanism, which has simple structure, safe and reliable performance, and is used for direct tension closed-loop control. [0004] The object of the present invention ...
