Steel coil height centering device and method

Abstract

The invention discloses a steel coil height centering device and a method thereof. The device is applied to height centering of a steel coil and the core shaft of an uncoiling machine during coiling, and comprises a coiling trolley; a saddle for mounting a steel coil, a lifting device for adjusting the height of the steel coil, a lifting encoder for recording the height of the steel coil lifted by the lifting device and a limiter for limiting a mechanical zero point are arranged on the coil trolley; upright columns are arranged on the two sides of the moving rail of the coiling trolley; a positioning light source for emitting a concentrated light beam is arranged on the upright column on one side, while a light receiving device for receiving the light emitted by the positioning light source is arranged on the upright column on the other side; the positioning light source and the light receiving device are located at the same height and the connecting line of the positioning light source and the light receiving device is perpendicular to the moving rail. The steel coil height centering method of the device is applied to centering in the axial direction of the steel coil, and the height difference between the upper edge and the lower edge of the inner diameter can be directly measured to determine the center of the steel coil. The steel coil height centering device is high in centering accuracy, stable and reliable and simple and convenient to operate.

Description

technical field [0001] The invention relates to the field of continuous metallurgical strip steel production lines, in particular to a steel coil height centering device and a method thereof. Background technique [0002] Coiling of steel coils is a key step in the continuous automatic production line. If a failure occurs, the entire production line may be shut down, so the coiling and uncoiling of steel coils is particularly important. If there is a problem with the centering calculation of the upper roll, it may cause roll over and equipment damage, and even endanger human safety. In the cold rolling continuous processing line, the coiling car first takes the steel coil from the saddle seat, and then the steel coil runs to the attachment of the uncoiler for height alignment, so that the height center of the steel coil is consistent with the center of the uncoiler mandrel. To ensure that the steel coil is inserted into the uncoiler. At present, some production lines use u...
