Problems solved by technology

[0003] During the cutting process of flying shears, the operator often changes the shearing point according to the actual production needs, which will cause the flying shears to report errors and stop cutting, thus affecting the normal production in the export area
In order not to affect the normal production in the export area of ​​flying shears, operators often manually stop the shearing point in front of the flying shears, and then start the flying shears to cut. Such a semi-automatic mode seriously affects the work efficiency of the export operators and increases the operating labor intensity

Abstract

The invention discloses a self-adaption flying shear positioning control method and device based on a shearing length and a computer readable storage medium. The method comprises the following steps:a positioning set value of a first shearing point and a positioning actual value of the first shearing point are obtained, wherein the first shearing point is a position of strip steel needing to be shorn; based on the positioning set value and the positioning actual value, a first positioning deviation of the first shearing point and a flying shear is determined; a correcting length is obtained;the first positioning deviation is corrected according to the correcting length; a second positioning deviation of a second shearing point and the flying shear is determined; the second shearing pointis a position of the strip steel redetermined to shear; and when the second shearing point reaches the flying shear, the speed of the strip steel is controlled to reduce to a speed set value based onthe second positioning deviation. The method eliminates the problem of failed positioning caused by manual change of the shearing length of the flying shear, improves the production efficiency of a production line, and greatly relieves the labor intensity of operators.

Description

technical field [0001] The invention relates to the technical field of steel rolling technology, in particular to an adaptive flying shear positioning control method and device based on shear length. Background technique [0002] A crank-type flying shear (flying shear for short) is installed at the exit section of the continuous annealing unit, and its function is to cut the weld seam, cut waste and take samples. Compared with traditional cross-cutting shears, flying shears do not have to stop the strip during shearing, but run at a low speed, thereby maintaining the continuity of strip operation and improving the production efficiency of the production line. [0003] During the cutting process of flying shears, the operator often changes the shearing point according to the actual production needs, which will cause the flying shears to report errors and stop cutting, thus affecting the normal production in the export area. In order not to affect the normal production in th...
