Method for checking levelness of straightening rollers of steel cold straightener

Abstract

The invention discloses a method for checking levelness of straightening rollers of a steel cold straightener, and belongs to the technical field of cold straightener straightening roller adjusting methods. The method is used for carrying out levelness checking on the straightening rollers of the steel cold straightener. According to the technical scheme, the roller way center line that is the rolling line and a point perpendicular to the roller way center line serve as the basis, through the distance measuring method, data are obtained, and whether the data meet the cosine law or not is usedfor judging the levelness of multiple movable points. Levelness measuring of the straightening rollers is converted into angle and straight line distance measuring, and single-point continuous changing measuring, the traditional levelness measuring method is broken through, and the new path is developed for straightening roller levelness measuring. Simple instrument equipment is adopted, the aim that a small device is used for measuring and calibrating a large machine device is achieved, in the measuring process, a measuring person can select the number of measuring points and the moving distance of the measuring points for measuring, measuring precision is controlled, and the measuring errors can be greatly reduced.

Description

technical field [0001] The invention relates to a method for verifying the levelness of straightening rollers of a cold steel straightening machine, and belongs to the technical field of adjustment methods for straightening rollers of cold straightening machines. Background technique [0002] The straightening rolls of the steel cold leveling machine are generally 5-roll, 7-roll or 9-roll straightening machines, which are divided into upper and lower rows and arranged horizontally. Pitch adjustment means that the straightening roller moves back and forth along the plane direction of steel production, vertical adjustment means that it moves up and down in the direction perpendicular to the pitch plane, and the axial direction means that it moves left and right along the direction of the roller axis. It is impossible to use the mechanical zero point for the zero point in the three directions, because there is an installation tolerance between the mechanical zero point and the ...

Problems solved by technology

[0003] At present, the measurement methods of the levelness of the three-dimensional three-dimensional coordinates include the level measurement method and the professional intelligent level measurement method. The above two methods are not suitable for the measurement of the flatness of some straightening rollers. The reasons are: first, the level method is used to measure The levelness of small devices and large machines are measured at several points. If a spirit level needs to be made with a level of more than 20 meters, the degree of waste can be imagined, and it is not the entire plane measurement, but only the measurement of several points in the plane. ;Professional intelligent level measuring instruments generally use infrared measurement, which is also not suitable for level measurement of straightening rollers, because infrared is a continuous signal, if it is blocked at one point, this surface is the end point of measurement, and the instrument is expensive and requires special personnel to operate

And the above two methods can only display the horizontal line, the specific horizontal data cannot be displayed directly, and the required adjustment value cannot be obtained

At present, there is no suitable method for measuring the levelness of straightening rollers in the industry. How to accurately and quickly check the levelness of straightening rollers has become a difficult problem that needs to be solved urgently
