Description

A cold-rolled strip deviation correction system

technical field

The utility model relates to a deviation correcting device for strip steel, in particular to a deviation correcting system for cold-rolled strip steel.

Background technique

At present, most of the cold rolling production units are continuous production, which is characterized by long production lines and high degree of automation. On a production line that is often hundreds of meters long, in order to ensure that the steel strip always runs along the center line, a deviation correction device is essential. At present, the commonly used strip correction system mainly uses a photoelectric inductive measuring system to scan the position of the edge of the strip, measure the two edges of the strip to calculate the difference between the measured values, that is, the deviation of the center position of the strip, and through the correction control The device compares the current value with the set value, and calculates the deviation, controls the output signal of the amplifier, and converts it into the range required by the electro-hydraulic servo valve through the power amplifier, and the servo valve controls the proportional flow (size, direction) of hydraulic oil to the cylinder, thereby generating Sufficient control torque to move equipment quickly.

However, for the cold-rolling production line, the incoming material is hot-rolled plate, which has poor shape and large edge waves, and the strip is easy to run off. The loop length of the cold-rolling production line can sometimes reach more than 400 meters. In the case of large deflection, the deflection correction effect of the existing deflection correction roller is very limited; and the deflection correction capability of the existing deflection correction system is directly related to the diameter of the roller. Due to the limitation of the installation space of the equipment, the roll diameter of the deflection correction roller cannot be increased without limit , thus restricting the improvement of the deviation correction ability.

Utility model content

In view of the above shortcomings in the prior art, the purpose of this utility model is to provide a cold-rolled strip deviation correction system, which can perform multi-dimensional deviation correction on the strip steel and improve its deviation correction ability.

In order to achieve the above object, the utility model adopts the following technical solutions:

The cold-rolled strip deviation correction system includes a deviation correction roller, a swing frame, a swing shaft and an oil cylinder. The shaft is used as a fulcrum for the deflection of the swing frame and is connected to one end of the swing frame; the oil cylinder is used as a driving part for the deflection of the swing frame and is connected to one side of the swing frame.

The inclination angle of the swing frame is an included angle of 5°-25° with the horizontal plane.

The swing frame is a rectangular frame structure.

One end of the swing frame is provided with two brackets, and the brackets are connected with the swing frame through a pin; the other end of the swing frame is provided with a bracket, and the bracket is also connected with the swing shaft through a pin.

In the above technical solution, the deviation correction system for cold-rolled strip steel of the present invention includes deviation correction rollers, a swing frame, a swing shaft and an oil cylinder. The two sides of the swing frame are connected in rotation; the swing shaft is used as a fulcrum for the swing frame deflection, and is connected to one end of the swing frame; the oil cylinder is used as a driving part for the swing frame deflection, and is connected to one side of the swing frame. When driven by the oil cylinder, the horizontal swing and vertical swing of the deviation correction roller can be realized, so that the original horizontal deviation correction becomes a multi-dimensional deviation correction form, and the deviation correction ability and effect are improved.

Detailed ways

The technical scheme of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

Please refer to Fig. 1 and shown in Fig. 2, the cold-rolled steel strip deviation correction system 10 of the present utility model comprises deviation correction roller 11, swing frame 12, swing shaft 13 and oil cylinder 14, and swing frame 12 is rectangular frame structure, and is inclined setting, After many repeated tests and calculations, the inclination angle is an angle of 5° to 25° with the horizontal plane. The deviation correcting roller 11 is arranged in the swing frame 12 , and the two ends of the roller are rotationally connected with both sides of the swing frame 12 through the roller shaft, so that the deviation correcting roller 11 can rotate freely in the swing frame 12 . The swing shaft 13 is used as a fulcrum for the swing frame 12 to deflect, and is connected to one end of the swing frame 12; One end of described swing frame 12 is provided with two supports 15a, and support 15a is connected with swing frame 12 by pin; The inclination of the swing frame 12 is achieved by the different heights of the brackets 15a, 15b at both ends.

When in use, one side of the swing frame 12 can be driven by the oil cylinder 14, so that the swing frame 12 can flip and swing along the swing axis 13 to the other side. Since the swing frame 12 is originally inclined, when the swing frame 12 swings, it can drive the deviation correction. While the roller 11 is deflecting, it also forms an integral angle, thereby producing multi-dimensional swing. Therefore, in addition to the stress in the original horizontal direction, the strip steel will also produce an "integral effect" during deviation correction, forming an integral deviation correction. Compared with the single horizontal swing correction method, it can significantly improve the correction ability without occupying much equipment installation space, meet the long-distance and short-distance correction needs of the looper, and adapt to the fast-paced production, multi-variety, and multi-specification cold rolling Products, avoiding the stable operation of the unit due to insufficient correction capability.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
