Problems solved by technology

[0006] Aiming at the problem of uneven temperature field distribution on the bending line and warping deformation caused by the moving heat source of the metal thin plate point spot in the bending process, the present invention uses a multi-mode laser scanning rotating mirror or a single piezoelectric deformable mirror to convert the point spot of the laser Gaussian distribution It is converted into a uniformly distributed linear spot and loaded on the bending line area at the same time to bend and shape the metal sheet, so that the temperature field on the bending line of the metal sheet is evenly distributed, so as to reduce warping deformation, improve the consistency of bending angle, and improve bending purpose of efficiency

Abstract

The invention belongs to the technical field of high-efficiency, high-precision and high-performance laser bending forming of metal plates, and relates to a linear spot laser bending forming method of metal thin plates. The present invention uses a multi-mode laser scanning rotating mirror or a single piezoelectric deformable mirror to convert the laser Gaussian-distributed point spot into a uniformly distributed line-shaped spot, and simultaneously loads it on the bending line area to bend and shape the metal sheet, so that the metal sheet bends The temperature field on the broken line is evenly distributed, so as to reduce warping deformation, improve the consistency of bending angle, and improve the bending efficiency.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency, high-precision and high-performance laser bending forming of metal plates, and relates to a laser bending forming method of a linear spot of a metal sheet, which is a laser bending method in which a line-shaped spot is heated simultaneously on a bending line of a metal sheet Forming method. Background technique [0002] Laser bending forming is a flexible, moldless, force-free and non-contact rapid prototyping technology, which is easy to realize automatic processing. The existing metal plate laser bending technology generally belongs to the point spot moving heat source, that is, the linear scanning sequential heating bending technology, the free end of the plate is warped and deformed due to the heat accumulation of the moving heat source and the influence of the boundary conditions of the plate. In high cases, this amount of deformation may cause major quality problems. According to ...
