Description

Automatic focusing high-efficiency laser cutting device

Technical Field

The invention relates to the technical field of laser cutting, in particular to an automatic focusing high-efficiency laser cutting device.

Background

Irradiating a cut material by using a high-power-density laser beam, heating the material to a vaporization temperature quickly, evaporating to form holes, continuously forming narrow (such as about 0.1 mm) cutting seams by the holes along with the movement of the material by using a light beam, and completing the cutting of the material, wherein the laser cutting can be divided into four types, namely laser vaporization cutting, laser melting cutting, laser oxygen cutting and laser scribing and fracture control cutting; the workpiece is heated by a high energy density laser beam, the temperature rises rapidly, the boiling point of the material is reached in a very short time, the material starts to vaporize, and vapor is formed. These vapors are ejected at a high speed, and a slit is formed in the material at the same time as the vapor is ejected. The heat of vaporization of the material is generally great, so great power and power density are required during laser vaporization cutting; the laser melting cutting is mainly used for cutting some materials or active metals which are not easy to oxidize, such as stainless steel, titanium, aluminum and alloys thereof; and (3) laser oxygen cutting. The laser oxygen cutting is mainly used for easily oxidized metal materials such as carbon steel, titanium steel, heat treatment steel and the like; laser scribing and controlling fracture; the laser scribing is to scan the surface of the brittle material by using high-energy-density laser to evaporate a small groove by heating the material, then apply a certain pressure to crack the brittle material along the small groove, and the laser cutting machine focuses the laser emitted from a laser into a laser beam with high power density through a light path system; the laser beam irradiates the surface of the workpiece to enable the workpiece to reach a melting point or a boiling point, and simultaneously, the high-pressure gas coaxial with the laser beam blows away the molten or gasified metal; and finally, the material is cut along with the movement of the relative position of the light beam and the workpiece, so that the cutting purpose is achieved.

The existing laser cutting machine can only move in the horizontal direction due to the fact that a laser cutting head can only move in the cutting process, and due to the fact that the size, the thickness and the shape of a workpiece are different, the power of laser cannot be adjusted constantly, and therefore the cutting depth of the positions with different sizes, thicknesses and shapes is caused to affect the cutting quality.
