Laser cutting machine applied to special-shaped sheet metal parts

Abstract

The invention discloses a laser cutting machine applied to special-shaped sheet metal parts. The laser cutting machine comprises a rack, a driving part and a laser cutting head are arranged on the rack, a sheet metal is placed on the table top of the rack, the driving part controls the laser cutting head to move in the horizontal direction to cut the sheet metal, and the laser cutting machine further comprises a protection block body; and a cutting groove position is reserved in the protection block body, the protection block body synchronously moves along with the laser cutting head through a control piece, the cutting groove position is always aligned with a laser beam of the laser cutting head, and the reserved cutting groove position is larger than the laser beam in size. The protection block body synchronously moving along with the laser cutting head is arranged, the cutting groove position is reserved in the protection block body, and the protection block body is arranged on the upper surface of the sheet metal part, so that splashing waste, sparks and the like fall on the protection block body, the sheet metal part is protected to a certain degree, and meanwhile consumption of protection gas in the laser cutting process can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of laser cutting equipment, in particular to a laser cutting machine applied to special-shaped sheet metal parts. Background technique [0002] The laser cutting machine focuses the laser light emitted from the laser device 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, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting. [0003] However, in the process of laser cutting sheet metal, problems are often encountered. For example, when a laser cutting machine cuts sheet metal by laser, the completely cut waste will usually fall down from the cutting hole under th...
