Abstract

The invention discloses a method and device for detecting the flexibility of a flat billet, and belongs to the technical field of steel forming and machining. The method and device are used for solving problems that a method for detecting the flexibility of the flat billet in the prior art is long in time in obtaining a detection result, is higher in subjectivity of an operator, and is lower in measurement precision. The method comprises the steps: obtaining a test image of a test piece according to set time and the movement speed of the test piece; carrying out the image processing of the test image, and obtaining the flexibility value of each test area of the test piece; and determining the position where the region with the maximum flexibility value is located according to the flexibility values of the test piece in different test regions.

Description

technical field [0001] The invention relates to the technical field of steel forming processing, and in particular to a method and device for detecting the deflection of a flat billet. Background technique [0002] Deflection refers to the linear displacement of the rod axis in the direction perpendicular to the axis or the linear displacement of the middle surface of the plate and shell in the direction perpendicular to the middle surface when the force or non-uniform temperature changes. [0003] At present, for the measurement of the deflection of the flat steel billet, there are mainly the following methods: contact measurement method, in which the measuring probe needs to be in contact with the flat steel billet with a certain pressure, and moves along the axial direction of the flat steel billet. The deflection of the flat billet in a certain direction can be determined by measuring the jumping range of the probe during the upward movement. Since in the above measurem...
