Abstract

The invention discloses a laser flattening method for a micro-deformed plate, wherein the laser heating effect is utilized to flatten the micro-deformed plate. According to the deformation form of theplate, different laser scanning paths are planed, the flattening angle needed by each path is determined, and the mapping relation between the angle and the highest temperature of single flattening and the laser power, the scanning speed and the scanning interval is established, according to a needed bending angle, appropriate technological parameters are selected, rapid detection is conducted toverify the effectiveness of the flattening technology, and the needed effective technological parameters are determined; the piece to be flattened is placed on a three-dimensional numerical control platform, a laser beam conducts continuous irradiation according to the planed scanning path at the selected technological parameters, the plate is made to be bent and deformed, and finally the micro-deformed plate is flattened. The laser flattening method for the micro-deformed plate is suitable for flattening the deformed plates which are complicated in shape and high in hardness and brittlenessand has large application prospect in the aerospace field and the microelectronics field.

Description

technical field [0001] The invention relates to a method for leveling micro-deformed plates by using laser thermal effect, belongs to the field of mechanical processing and manufacturing, and can be applied to the leveling process of complex-shaped plates or plates prone to rebound. Background technique [0002] In the field of industrial manufacturing, due to the influence of transportation conditions, processing technology and material properties, metal sheets will undergo unexpected micro-deformations in different situations during use. This deformation will affect the equipment accuracy of parts and even affect the service life of the overall mechanical equipment. . At present, the leveling methods used for the undesired deformation of plate parts mainly include mechanical leveling and thermal leveling. Among them, mechanical leveling mainly uses mechanical external force to stamp the plate, which can only level some materials with better plasticity, and the leveling ef...
