Laser forming method for metal sheet

Abstract

The invention discloses a laser forming method for a metal sheet. According to the laser forming method for the metal sheet, appropriate and unique technological parameters in a laser bending forming method are selected to accurately control the deformation amount of the metal sheet and obtain the metal sheet with continuous bending deformation. The interval between every two adjacent paths is preferably 1.5-2 millimeters, the reciprocating scanning times of each path is preferably 10 times, the diameter of each laser beam spot is 0.1 millimeter, the power is 20-25 watts, the scanning speed is 15-20 millimeters, and the curvature of a finally obtained thin sheet is about 0.05-1 millimeter.

Description

technical field

[0001] The invention relates to a laser processing and forming method, in particular to a laser bending and forming method for metal plates. Background technique

[0002] The forming process of sheet metal occupies a considerable proportion in aviation, aerospace, automobile, shipbuilding and civil industries. For example, the number of plate forming parts accounts for 1 / 2 of the total number of aircraft parts. According to statistics, more than half of the materials produced in the world are processed into plates. Therefore, improving the corresponding forming technology and manufacturing level is a subject of universal significance.

[0003] The core issues of modern sheet metal forming technology are concentrated in the aspects of simplifying design, improving quality, shortening cycle and reducing cost. Traditional forming technology usually needs to manufacture corresponding tools and molds according to the shape of the plate, which not only takes a lo...
