[0003] When laser cutting thin steel plates, the focused laser beam is shot at the material to be cut through the nozzle, thereby forming a jet of air, the material is quickly heated to the melting and vaporization temperature, and a high-speed air flow will melt from the coaxial or non-coaxial side And the vaporized material is blown out from the cutting slit to form a hole for material cutting. With the relative movement of the focus and the material, the hole forms a continuous narrow slit to complete the cutting of the material. However, the melted and vaporized material The wind spreads in the shape of a trumpet under the cutting seam. In the contact area with the bottom edge of the cutting seam, the partially vaporized material is cooled and condensed into small droplets that accumulate on the edge of the incision. Secondly, for the thin steel plate, it gathers on the When the jet hole of the cutting point passes by, it will produce pressure and vibration on the surface of the cutting point, which will cause local depressions and affect the smoothness of the cutting edge

The invention belongs to the technical field of metal processing, and particularly relates to thin steel plate laser cutting equipment with a blowing device. According to the problem that molten and vaporized materials are diffused and distributed in a trumpet shape below a cutting seam, parts of the vaporized materials are cooled in a contact area with the bottom edge of the cutting seam, and the materials are congealed into small-particle droplets to be accumulated at the cutting opening edge, the following scheme is put forward. The device comprises a machine tool platform, a main walking mechanism is fixedly installed at the top of the machine tool platform, and an auxiliary walking mechanism synchronous with the main walking mechanism is fixedly installed in the machine tool platform. The circulating speed of the gasified materials at the cutting opening part is increased, generation of small-particle crystals of the materials is reduced, the cutting point area is made more stable during cutting under the action of upward pressing and downward sucking, a stepping motor drives a pipe body and a grinding mechanism to rotate in the cutting process, and the small-particle crystals generated on the surface of the lower cutting opening are effectively removed. And the smoothness of the cutting opening is improved.
Description
technical field [0001] The invention relates to the technical field of metal processing, in particular to a thin steel plate laser cutting equipment equipped with a blowing device. Background technique [0002] The laser cutting machine focuses the laser emitted from the laser into a high-power-density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will melt or The vaporized metal is blown away, and with the movement of the relative position of the beam and the workpiece, the material finally forms a slit, so as to achieve the purpose of cutting. The laser cutting machine generally consists of a cutting head, a workbench, a microcomputer numerical control cabinet, a cooler and a computer. Composition, through the walking mechanism on the worktable to realize the X, Y, Z axis movement of the cutting h...
