Problems solved by technology

[0005] However, the above-mentioned automatic shearing mode of thickened plate is to identify the profile of thickened plate through thickness measurement and length measurement, and determine the shear position of a single inflection point, which requires high accuracy of rolling length. When the thickness exceeds the set tolerance range, the existing automatic cutting mode cannot identify the inflection point, that is, stop cutting, resulting in low cutting efficiency

Abstract

The invention discloses an automatic compensation shearing method based on the recognition of any inflection point of a thickened plate, which comprises the following steps: 1) inputting normative data on the thickness and length of each segment of the thickened plate in the operation interface of a shear control system; 2) Select any inflection point on the first section as the set inflection point; 3) The shear control system automatically collects the real-time data of the thickness and length of each section of the thickened plate, matches with the input specification data, and automatically calculates the position of the inflection point; 4) The cutting control system determines the cutting position according to the length value from the set inflection point to the end of the section, and completes the automatic cutting; 5) When the size of a certain section of the thickened plate deviates, the cutting control system will automatically and dynamically compensate. The invention matches the collected real-time data of thickness and length with the standard specification data, automatically calculates the position of the specified inflection point, and then completes the cutting according to the set length. If the current part cycle size deviates, it will automatically and dynamically compensate for the next part cycle cutting .

Description

technical field [0001] The invention relates to an automatic compensation shearing method for a variable thickness automobile plate, in particular to an automatic compensation shearing method based on the recognition of any inflection point of a variable thickness plate. Background technique [0002] Thickened plate is a material with special effects of thickness change, which is obtained by flexible rolling on a rolling mill. Such as figure 1 As shown, in the rolling process, with the help of the rolling thickness automatic control system (hydraulic AGC) of the rolling mill, the position of the rolls is controlled, and the spacing is adjusted and changed in real time, so that the rolled thin plate is rolled along the steel plate. It has a pre-customized variable thickness distribution in the manufacturing direction. [0003] There are two types of thickened plates: non-coated thickened plates and coated variable thickness plates (including thickened plates with aluminum-s...
