At present, the products and patents related to the detection and adjustment of the shear edge curve of the sheet mainly include: Jiangsu Zhongwei Heavy Industry Machinery Co., Ltd. produces the Q11Y / K-20×12500 CNC gate shearing machine with a plate width of 12.5m and a plate thickness of 20mm , the method of blade position detection and deformation compensation is simple, manual operation is labor-intensive and has large errors, which seriously affects the shearing production efficiency and production quality; a numerically controlled hydraulic gate shearing machine (patent application number 201120154344.X) has passed the Input relevant working parameters through the buttons on the control panel of the CNC numerical control system to realize the automatic cutting work of the shearing machine
It uses the numerical control system to adjust the position of the blocking device and correct the angle of the knife holder, which eliminates the large errors caused by manual adjustment to a certain extent, but because it only adjusts the width of the sheet, it lacks automatic detection of the edge curve of the sheet after shearing , the edge curve error is still large after cutting, and the quality cannot be guaranteed
[0004] To sum up, at the present stage, the on-line detection and pre-adjustment compensation technology of the blade position and the shearing edge of the super-large shearing machine is mainly based on manual detection and adjustment, and manual detection of the shearing edge of the plate and the position of the tool is time-consuming. , Large error, manual compensation and adjustment of the blade position of the tool, large workload, low efficiency, large error and other deficiencies seriously restrict the development and popularization of super-large shearing machine technology, and there is an urgent need to develop super-large shearing machine sheet shearing edge deformation Quantity automatic compensation system and method

The invention discloses an automatic plate shearing edge deformation compensation system and method for an ultra-large plate shearing machine. A CCD (charge coupled device) industrial camera is used for photographing a plate shearing edge to obtain edge curve data of a plate after trial shearing, detection is rapid and accurate, efficiency is high, an image acquisition card acquires the data and transmits the data to a Sysmac automation platform for processing the data to obtain an edge curve of the plate, an edge adjusting curve of a lower shearing tool and the number of rotating turns needed by each jack and tension adjusting bolt at an adjusting point, control signals are transmitted to an automatic tool deformation adjusting device, and deformation of the lower shearing tool is changed by an adjusting bolt assembly. Cutting edge deformation adjustment can be greatly accelerated based on liberating manual adjustment, and working efficiency and operating accuracy are greatly improved.
