[0002] Sheet metal bending and laser cutting is an advanced metal processing technology that combines the advantages of sheet metal bending and laser cutting to achieve efficient and precise processing of sheet metal materials.

[0003] The technical principle of sheet metal bending and follow-up laser cutting is mainly divided into two parts. The laser cutting part is that the laser generator generates a high-power density laser beam, and the laser beam is focused on the surface of the sheet metal material through a focusing lens. The energy of the laser beam is absorbed by the material and quickly converted into heat energy, causing the material in the irradiated area to melt or even evaporate instantly. At the same time, the high-pressure auxiliary gas jet helps blow away the molten metal to form a precise cutting gap. The bending part is to bend the sheet according to the preset trajectory through a precise control system. During the bending process, the laser cutting head can follow the movement of the sheet to cut, realizing the integrated operation of bending and cutting.
