Abstract

The invention provides an aluminum alloy laser drilling method and device, and the method and device are suitable for the technical field of laser machining. The method and device aim to achieve the goal of eliminating the through hole taper generated in the aluminum alloy laser drilling process in the prior art. The aluminum alloy laser drilling method includes the following steps of laser drilling, solution configuration and through hole corrosion. The invention further provides an aluminum alloy laser drilling device. According to the aluminum alloy laser drilling method, laser beams are adopted to machine through holes in the surface of aluminum alloy, the through holes are provided with tapers, and the through hole tapers are eliminated through chemical reaction between the chemical solution and the aluminum alloy, so that the through holes without the tapers are obtained. The method is high in machining efficiency and the aluminum alloy is free of deformation.

Description

technical field [0001] The invention belongs to the technical field of laser processing, in particular to an aluminum alloy laser drilling method and device. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for processing through-hole components of aluminum alloys is increasing, and the research on through-hole processing of aluminum alloys is also in-depth. [0003] The traditional methods for machining through-holes in aluminum alloys include die punching, drilling, and electric sparks. However, these processing methods cannot overcome the problems of deformation and processing efficiency of aluminum alloy materials. For example, die punching has high requirements for punches and c...
