Laser cutting machine and working method thereof

Abstract

The invention relates to a laser cutting machine and a working method thereof. Like a small-breadth laser cutting machine, the laser cutting machine of the invention has high cutting quality, high efficiency and high accuracy, and the consumed power of a driving system in the cutting process is smaller. The laser cutting machine comprises a stand provided with an X lead rail, a main beam provided with a Y lead rail and a laser head seat, wherein the main beam is movably connected with the X lead rail on the stand; the laser cutting machine also comprises a cantilever beam for a laser head to realize short-distance movement in the X direction; the cantilever beam is provided with an X short lead rail; the root of the cantilever beam is movably connected with the Y lead rail on the main beam to enable the cantilever beam to make Y-direction movement; and the laser head seat is movably connected with the X short lead rail. The working method comprises the following steps: 1. installing a buffer area on the short lead rail; 2. according to different processing requirements, calculating by different steps respectively; and 3. starting the laser cutting machine according to the calculating to manufacture. In the invention, a vector control principle is adopted to synthetize VX minor-axis speed, VX long-axis speed and VY speed so as to effectively control the speed in processing to ensure the processing quality.

Description

technical field [0001] The invention relates to a laser cutting machine and a working method thereof, in particular to an improvement of a heavy-duty large-format thick plate laser cutting machine and a working method thereof. Background technique [0002] Wide and large-format laser cutting machines have great market application prospects. Because of their large cutting widths, the weight of moving parts is usually large. For example, the weight of the main beam alone is 2-3 tons, plus laser generators, water coolers, etc. , about 4-5 tons in weight. The main disadvantages of the large weight of the main beam are: 1. The large weight and inertia make the dynamic response speed of the main beam movement poor, which has a great impact on the machining accuracy and quality. 2. The rigidity of the main beam structure is poor, which will cause a large positioning error of the transmission system. The above two problems make the existing equipment have low precision, low qualit...
