Multi-end laser cutting head

Abstract

The invention discloses a multi-end laser cutting head and belongs to the technical field of application of laser cutting machinery. The multi-end laser cutting head comprises a base, a collimating mirror is mounted on one side of the base, the top end of the collimating mirror is connected with a laser with a connector, a beam splitter and reflectors are arranged in the base, and the beam splitter is communicated with the inside of the collimating mirror. Cutting ends are mounted at the bottom of the base and nozzles are mounted at the bottom ends of the cutting ends. Focus lenses are arranged in the cutting ends and are connected with adjusting nuts on the side walls of the cutting ends, and a beam adjuster is arranged between the cutting ends and the base and is communicated with the beam splitter and the reflectors. The multi-end laser cutting head is added into a beam splitting system and a beam quality adjusting system, so that on the premise of the same cutting quality, efficiency is improved by several times, machining cost is greatly reduced, laser cutting kerf is narrow, workpiece deformation is small, operation efficiency is high, and the nozzles can well protect the focus lenses.

Description

technical field [0001] The invention relates to a cutting head, in particular to a multi-head laser cutting head, belonging to the technical field of laser cutting machinery application. Background technique [0002] With the development of science and technology and the application of laser in cutting machinery, laser cutting machine is the most demanded product of laser equipment in the world. It uses high energy density laser beam to melt or vaporize the material, and blows off the molten material with auxiliary gas to form a slot . Laser cutting has a narrow slit, almost no cutting residue, small heat-affected zone, and low cutting noise. It can quickly complete the manufacturing process according to the AutoCAD design file, and does not need to increase other mold costs. At present, the lasers used include YAG lasers, fiber lasers and CO2 laser. Due to its superior beam quality and convenient optical transmission characteristics, fiber lasers have developed rapidly in...

Problems solved by technology

[0003] There are many deficiencies in the current laser cutting heads in the market. For example, the mainstream technology is laser single-head processing, which is not high enough in cutting efficiency, resulting in high processing costs. When using ordinary laser cutting heads, there is no good spectroscopic system and The beam adjustment device makes the laser cutter have poor cutting effect, low cutting precision, and poor surface quality of the cut workpiece. It can only be used in some rough processing applications. On the other hand, ordinary laser cutters are only simple Cutting with a single laser cutting head has low work efficiency. Therefore, a multi-head laser cutting head is proposed to solve the above problems
