Abstract

The invention relates to a thick plate myriawatt-level fiber laser perforation method, which comprises a conventional cutting machine mounted on a cutting platform, and comprises the following steps: S1, an optical control module is added on the conventional cutting, and the optical control module comprises a perforation focus lens module and a cutting focus lens module; s2, a workpiece to be cut is placed on a cutting platform, and a punching focus lens module is selected; s3, setting hole parameters of the punching focus lens module, such as laser power, pulse form and light emitting time; s4, a punching focus lens module is opened, and punching is carried out; and S5, a control system of a conventional cutting machine is used, a punching focus lens module is switched, and cutting is carried out. The device has the advantages that the optical module is added, the focusing diameter and the Rayleigh length of a laser beam are controlled, and the high-power laser drilling quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a method for perforating a thick plate with a 10,000-watt fiber laser. Background technique [0002] Laser perforation is the pre-process of thick plate laser cutting, and the efficiency and quality of perforation are the key to thick plate laser cutting technology. [0003] Currently known laser perforation methods are as follows: [0004] 1. The Chinese patent is a step perforation system for laser cutting medium and thick plates, the announcement number is CN 202854559 U, and the announcement date is April 3, 2013. During operation, the main parameters of the method continuously change step by step within the perforation time according to a certain law, so as to match the optimal parameters, so as to reduce the perforation time, avoid local overheating, reduce the explosion rate, and avoid damage to the focusing mirror. The penetration of fine pores is completed in ...
