Metal plate laser cutting machine

Abstract

The invention relates to a metal plate laser cutting machine. The metal plate laser cutting machine comprises a machine tool main body, a nozzle, a clamping groove, a clamping frame, ejecting devices,a clamping groove and a clamping device; the nozzle is mounted on the machine tool main body; the clamping groove is mounted on the outer wall of the nozzle; the clamping frame is clamped in the clamping groove; the ejecting devices are uniformly mounted in the clamping frame; the clamping groove is formed in the front side in the clamping frame; and the clamping device is mounted in the clampinggroove. The metal plate laser cutting machine can solve the following difficulties: totally cut wastes can fall down from cutting holes under the gravity effect when metal plates are cut through laser by a traditional laser cutting machine; when the metal plates are thicker, the inclined falling condition of the wastes is possibly generated during falling to cause blockage of the wastes in the cutting holes in the falling process; and spark is frequently generated during cutting of the metal plates by the laser cutting machine, and is easy to splash to non-machining areas of the metal platesto cause more cakes around the metal plates, so that the laser cleaning is more difficult.

Description

technical field [0001] The invention relates to the field of laser cutting machines, in particular to a sheet metal laser cutting machine. 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 beam and the relative position of the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting. However, in the process of laser cutting sheet metal, the following problems are often encountered: [0003] 1. When the laser cutting machine cuts the sheet metal through the laser, the completely cut waste will usually fall down from the cutting hole under the action of gravity, but when th...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that when the existing laser cutting machine cuts the sheet metal by laser, the completely cut waste usually falls from the cutting hole under the action of gravity, but when the thickness of the sheet metal is thicker, the waste may fall The situation of inclined falling causes the waste to be stuck in the cutting hole during the falling process. When the laser cutting machine cuts the sheet metal, it is often accompanied by sparks. The sparks are easy to splash into the non-processing area of ​​the sheet metal, resulting in more agglomerations around the sheet metal processing. , difficult to clean up later
