Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0023] Such as figure 1 and figure 2 , a test device for the gas flow field structure of the slit in the laser cutting process, comprising: a gas injection module with a nozzle 1, two pieces of plexiglass 2 relatively parallel to each other, a thin metal plate with an oblique angle 3, a CCD camera 4, Supporting plate 5; the inner walls of the two pieces of plexiglass 2 facing each other are coated with viscous fluid.
[0024] Wherein, the metal thin plate 3 with an oblique angle is fixed between the opposite surfaces of two pieces of organic glass 2; the two pieces of organic glass 2 and the gas injection module are fixed on the support plate 5; The top of the glass is set corresponding to the oblique angle of the thin metal plate 3 . Described CCD camera 4 is positioned at the outside of any plexiglass, and is arranged in parallel with plexiglas...
