Abstract
The invention relates to a laser forming technique for a curved plate. According to the laser forming technique, a PLC, a laser generator, a high-strength laser beam, a movable workbench, an adjustable module, a zero datum line, fixing devices and a sheet are involved. The laser generator and the movable workbench can be controlled through the PLC, the high-strength laser beam is irradiated to the center line of the sheet, limiting devices are arranged on the two sides of the movable workbench, and the fixing devices are arranged on the two sides of the sheet. The set position of the zero datum line is as high as the upper portion of the movable workbench. The fixing devices are made of rubber. The PLC is used for controlling the movable workbench so as to drive the sheet to move, the high-strength laser beam is made to carry out scanning irradiation from one end to the other end of the center line of the sheet, the metal sheet is curved and deformed by generated thermal stress, and the curving angle is determined by the number of times of scanning of the high-strength laser beam. According to the technique, the equipment is simple, forming is achieved without molds, and the production cycle is short; the deformation resistance of the curved plate is improved.
