Description

Stable laser cutting machine base

Technical Field

The utility model relates to a laser cutting machine technical field especially relates to a stable form laser cutting machine base.

Background

The laser cutting machine focuses laser emitted from a laser into a laser beam with high power density through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece 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 laser cutting processing is to replace the traditional mechanical knife by invisible light beams, has the characteristics of high precision, quick cutting, no limitation on cutting patterns, automatic typesetting, material saving, smooth cut, low processing cost and the like, and can gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser tool bit is not in contact with the workpiece, so that the surface of the workpiece cannot be scratched in the working process;

compared with the traditional oxyacetylene and plasma cutting process, the laser cutting speed is high, the cutting seam is narrow, the heat affected zone is small, the verticality of the cutting seam edge is good, the cutting edge is smooth, and meanwhile, the types of materials capable of being cut by laser are various, including carbon steel, stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramic, glass, composite materials and the like.

During the cutting process of the laser cutting machine, a light beam is focused into a small focal point through a lens of a cutting head, so that high power density is achieved at the focal point, wherein the cutting head is fixed on a z-axis. At this time, the heat input by the light beam far exceeds the partial heat reflected, conducted or diffused by the material, the material is heated to the melting and vaporizing temperature quickly, and simultaneously, a high-speed airflow blows out the melted and vaporized material from the coaxial or non-coaxial side to form a hole for cutting the material. And with the relative movement of the focus and the material, the hole forms a continuous slit with a narrow width, and the cutting of the material is completed.

At present, chinese patent publication No. CN108480868A discloses a laser cutting machine base with a protective structure, which includes a double-layer protective mechanism body, a first protective mechanism, a second protective mechanism, a Y-axis beam, a hinge, a movable slider, a connection fixing rod, a beam base, a reinforcement bar fixing strip, an X-axis beam connecting bracket, base side beams, an X-axis beam, a beam pillow, a beam end fixing connecting plate, a fastening connecting piece, an adjusting slider, a movable guide rail, a beam connecting mechanism, a support frame a, a support frame B, a support frame C, a connection fixing block, and a steel plate are disposed on the double-layer protective mechanism body, a Y-axis beam and an X-axis beam are installed between the base side beams on both sides of the double-layer protective mechanism body, the Y-axis beam and the X-axis beam are cross-connected and fixed with each other, and the cross sections of the Y-axis beam and the X.
