Description
Technical Field
The application relates to the technical field of laser processing, in particular to a laser shot blasting forming large-format dynamic scanning closed-loop control system and method.
Background
The laser shot blasting is to generate a high-amplitude residual stress field on the surface and the depth direction of the part by utilizing a plasma impact mechanical effect generated by laser induction, so that the part is bent and deformed. The process can effectively improve the anti-fatigue and corrosion resistance of the part, and has wide application prospect in the forming of large-scale integral wallboards for aerospace, rail transit and the like due to the unique technical advantages.
For laser shot-peening forming of large integral wall plates, there are generally two modes and devices of fixed light path and dynamic scanning. For a fixed light path forming mode, a laser shot-peening forming system for controlling workpiece movement by utilizing a five-axis linkage numerical control machine tool is proposed by the prior patent 'method and device for laser shot-peening forming of medium plate' (patent number ZL 200510040116.9). Or the optical path is kept still, and the robot is used for clamping and controlling the movement of the workpiece to realize laser shot-peening forming. The disadvantage of this fixed optical path is that the requirement for equipment movement and processing space is high in order to move the workpiece, and it is difficult to meet the forming requirements of larger workpieces.
For a dynamic scanning type forming system, the prior patent 'an optical path device and a method for laser shot peening forming of a large workpiece' (patent number CN 201510197097.4) provides a large-format dynamic scanning device suitable for the large workpiece, the spot shape adjustment at different positions is realized through the forward and backward movement and synchronous rotation of two orthogonal cylindrical mirrors, the dynamic scanning of the laser large format is realized through a two-axis vibrating mirror, the optical path device is simple to arrange, easy to move and small in range, the dynamic correction and focusing of the spot shape at any position in space are ensured, and the method is an effective mode for realizing the laser shot peening forming of a large-format wallboard. However, the current dynamic scanning forming system is mainly realized by respectively controlling and independently operating an optical system (comprising a galvanometer, an optical path correcting and focusing module and the like) and a laser, and the movement speed of the optical system needs to be matched with the light-emitting frequency of the laser. However, when the movement speed of the optical system cannot be matched with the light-emitting frequency of the laser or the vibrating mirror jumps in a large range, the problems of inaccurate light-emitting position, missing processing points or multiple light-emitting exist, the accurate control of laser pulses is difficult to realize, and the forming quality of the wallboard is affected.
