Embodiment Construction

[0040] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] See attached Figure 1-5 , an automatic focusing cutting head for an optical fiber laser cutting machine of the present invention, comprising a cutting head main body, a focusing mirror drawer, a protective lens drawer, a reflective lens, and a CNC. The focusing mirror drawer is located on the protective lens drawer, and the protective lens drawer Located above the cutting head body, also includes:

[0042] The perforation detection unit realizes controllable fast perforation, starts cutting immediately after the perforation is completed, without waiting time, monitors the blasting state during the perforation process and makes intelligent adjustments to the perforation laser power. At the same time, it has the function of focusing lens temperature detection, real-time monitoring of temperature, and stable cutting without human...

Abstract

The invention relates to an automatic focusing cutting head for an optical fiber laser cutting machine and a control method. The automatic focusing cutting head comprises a cutting head body, a focusing lens drawer, a protection lens drawer, a reflection lens and a CNC; the focusing lens drawer is located above the protection lens drawer located above the cutting head body; the automatic focusing cutting head further comprises a punching detecting unit and an automatic focusing lens system, the reflection lens is located between the automatic focusing lens system and the punching detecting unit, and the punching detecting unit is located above the focusing lens drawer; and the CNC is electrically connected with the automatic focusing lens system and the punching detecting unit. According to the automatic focusing cutting head, automatic control over focus and punching time in the full cutting process from punching to cutting is achieved, manual intervene is not needed, the cutting efficiency and the automatic level are greatly improved, and the excellent good market prospect is achieved.

Description

technical field [0001] The invention relates to a laser processing device, in particular to an automatic focusing cutting head for an optical fiber laser cutting machine, and also relates to a control method for an automatic focusing cutting head for an optical fiber laser cutting machine. Background technique [0002] Laser cutting machines are used more and more in industry. The laser cutting process includes the perforation and cutting process. When perforating, whether it is carbon steel or stainless steel, when the focus is on the surface of the material or below the surface of the material, the perforation efficiency is higher, but for cutting, carbon steel and stainless steel are Different. When cutting materials with different thicknesses, the depth of the focus distance from the surface of the plate is different, and it needs to be adjusted in time according to the type and thickness of the plate. [0003] As far as the piercing process is concerned, for thick pla...
