Embodiment Construction
[0057] The invention will be further described below in conjunction with the accompanying drawings and specific implementation examples.
[0058] Such as figure 1 As shown, an optimal shearing method for wide and thick plates based on shape recognition includes:
[0059] Step 1: Collect the image of the wide and thick plate to be cut, and extract the data points of the edge contour of the wide and thick plate according to the image information of the wide and thick plate;
[0060] Use wide and thick plate shape recognition equipment to collect images of wide and thick plates running at high speed on the 4300mm wide and thick plate production line. The shape recognition equipment is installed at the exit of the thermal straightening machine, and a laser speedometer is installed at the entrance of the cutting head. The shape recognition equipment mainly includes Three profile detectors, laser velocimeter, cooling protection box, special lens and hood, shock absorber, etc. In th...

The invention provides an optimized cutting method for wide and thick plates based on shape recognition. The image of the wide and thick plate to be cut is collected, and the data points of the edge contour of the wide and thick plate are extracted according to the image information of the wide and thick plate. The tail length calculates the effective length of the wide and thick plate; then calculates the side bending and effective width of the wide and thick plate according to the data points of the edge profile of the wide and thick plate; finally formulates an optimized shearing strategy according to the planar shape characteristics of the wide and thick plate and the order information of the sub-plate, the present invention It can effectively and quickly make decisions on each steel plate, including judging whether the steel plate needs to be cut off the line according to the characteristics of the plane shape, avoiding unnecessary processing, and can also calculate the rough division position of the steel plate, combined with the laser speedometer for precise cutting. Improve the finished product rate, save labor and management costs, and are suitable for automatic shearing operations of wide and thick plates running at high speed.
Description
technical field [0001] The invention relates to the technical field of automatic control of wide and thick plate rolling, in particular to an optimized shearing method for wide and thick plates based on shape recognition. Background technique [0002] Wide and thick plates are widely used in ships, bridges, boilers, containers, petrochemicals, engineering machinery and national defense construction. In the production process, due to the complexity of the production process, the planar shape of the rolled product deviates from the rectangular shape. A shearing process is required for further processing. However, the operation of the cutting line is complicated. In most cases, workers need to judge the length of the motherboard, the size of the side bend and the position of the cutting head by visual inspection and combined with production experience, which may easily lead to short rulers and errors in rough division. [0003] With the rapid development of communication techn...
