Problems solved by technology

If the tension is too high, the edges will warp easily, and steel will stick to the steel during annealing; if the tension is too small, the steel coil will collapse during storage, and the coil will slide during flattening and slitting, causing scratches
[0003] Usually the steel strip coiler comes with a PLC program that can control the winding tension, and the degree of automation is high, and the technology is very mature, but the tension controlled by the PLC program is automatically calculated by the internal program of the system, and other factors affect the tension output. When the PLC program cannot respond properly, for example, the temperature difference between summer and winter will affect the viscosity of the gear oil of the winding machine. In winter, the viscosity of the gear oil increases when the temperature is low, and the mechanical resistance that the winding machine needs to overcome is much higher than that in summer. , it will cause the same set tension input value to output different tension values ​​at different times, which will cause the actual winding tension of the steel strip to change.

Embodiment 1

[0015] The invention discloses a double-tension control device for steel strip winding, which includes a winding machine with a PLC tension control device. The input end of the winding machine is equipped with a tension measuring device, and the tension measuring device is used to detect steel Take the actual winding tension, and transmit the actual winding tension to the PLC tension control device.

[0016] Described tension measuring device is made up of the first turning roller, the second turning roller, the third turning roller and the tension sensor installed on one of the turning rollers of the three turning rollers; the first turning roller, the second turning roller and the first turning roller The three turning rollers are arranged in an equilateral inverted triangle and are parallel to each other, the third turning roller is located at the top of the inverted triangle, the first turning roller and the second turning roller are located at two bottom corners, and the e...

Embodiment 2

[0019] The invention discloses a control method of the double tension control device for steel strip winding, which includes the following steps:

[0020] 1) Use the tension measuring device to detect the actual winding tension of the steel strip;

[0021] 2) The actual winding tension detected by the tension measuring device is transmitted to the PLC tension control device on the winding machine, and the tension of the winding machine itself is corrected by the preset adjustment coefficient program in the PLC tension control device.

[0022] The actual winding tension of the steel strip is measured by the tension measuring device, which is used to correct the PLC tension control program that comes with the winding machine. A tension sensor is installed on the tension measuring device. When no steel strip passes by, adjust the tension sensor to return to zero. When a steel belt passes through, the tension sensor can detect the tension value on the steel belt.

Abstract

The invention discloses a double-tension control device and method for steel strip winding. Wherein an actual winding tension of a steel strip is detected by adopting a tension measuring device, the PLC tension control system of a winding machine is corrected by using an adjusting coefficient function in a PLC tension control program of the winding machine, therefore, the winding tension of the winding machine is ensured to be consistent with or more close to a winding tension of actual detection, the precision of the winding tension is improved, the double-tension control device and method for the steel strip winding can be widely applied to steel strip cold rolling unit, continuous surface treatment unit, and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a double tension control device and method for steel strip winding. Background technique [0002] The winding device is widely used in steel strip cold rolling, continuous surface treatment and other units, and is an indispensable part of continuous operation of equipment. Winding tension control is also a key parameter in the steel strip production process. The tension will affect the subsequent processing procedures, such as annealing, leveling, and slitting. If the tension is too high, the edges will warp easily, and steel will stick to the steel during annealing; if the tension is too small, the steel coil will collapse during storage, and the coil will slide during flattening and slitting, causing scratches. [0003] Usually the steel strip coiler comes with a PLC program that can control the winding tension, and the degree of automation is high, and...
