Laser cutting system facilitating angle adjustment

Abstract

The invention discloses a laser cutting system facilitating angle adjustment. The laser cutting system comprises a numerical control module and a follow-up control module. The follow-up control module comprises a connecting rod, and a laser cutting assembly and a cooling module which are connected through the connecting rod; the laser cutting assembly and the cooling module each comprise a shell, a plurality of annular guide rails and a plurality of linear guide rails on the surface of the shell, sliding blocks arranged on the surfaces of the annular guide rails or the linear guide rails, and laser heating units or cooling units connected to the surfaces of the sliding blocks. The shell is of a hollow inverted-cone-shaped structure, the linear guide rails are arranged in a radial mode, and the annular guide rails are arranged at equal intervals. The laser cutting system is suitable for high-precision metal products needing complex pattern machining, and the positions of the sliding blocks on the linear guide rails and the annular guide rails on the shell of the inverted-cone-shaped structure are adjusted, so that the sliding blocks rotate at different angles on the surface of the inverted-cone-shaped structure, the laser heating units can cut the processed object along an expected track, and dead angles of laser cutting are reduced.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting system which is convenient for angle adjustment. Background technique [0002] Laser cutting is to irradiate the steel frame with a focused high-power-density laser beam, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the beam, so as to realize the The processed product is cut. [0003] Laser cutting is thermal processing, and thermal damage will occur at the processing site. The existing laser cutting system mainly has the following problems: 1. The laser cutting process directly vaporizes the material, and stress accumulation will occur at the cutting place, causing the deformation of the material to increase. Due to the instantaneous thermal expansion and contraction effect, the material itself will expand a...

Problems solved by technology

The existing laser cutting system mainly has the following problems: 1. The laser cutting process directly vaporizes the material, and stress accumulation will occur at the cutting place, causing the deformation of the material to increase. Due to the instantaneous thermal expansion and contraction effect, the material itself will expand and contract instantaneously. As a result, the material is damaged, so different parts of the material will be deformed to varying degrees when laser cutting the material, resulting in an increase in the defective product rate of the product; 2. The existing laser cutting cannot adapt to high-precision metal products that require complex graphic processing, and it is difficult to Control the cutting of different angles of the laser beam during laser cutting, and there are many dead angles in laser cutting
