A laser shock strengthening processing system

Abstract

The invention discloses a laser impact strengthening processing system, belonging to the technical field of laser impact strengthening, which can solve the problem that when the existing laser impact strengthening processing system processes complex parts or different types of parts, processing heads with different functions need to be replaced, and the steps are cumbersome and complicated. problem of inefficiency. The system includes: a laser; an optical module, which is hermetically connected to the laser; including an accommodating box and a reflection unit arranged in the accommodating box. Or at least two of the bottom surfaces are provided with a second window sheet; a control module, connected with the reflection unit, is used to control the rotation and movement of the reflection unit; a plurality of processing heads, each of which is sealed and connected to the accommodating box and is provided with a on the outer surface of the side wall of the corresponding second window; the processing head is used for processing the workpiece to be processed by using the laser beam transmitted from the corresponding second window. The invention is used for laser shock strengthening processing of workpieces.

Description

technical field [0001] The invention relates to a laser impact strengthening processing system, which belongs to the technical field of laser impact strengthening. Background technique [0002] Laser shock peening is an advanced technology for surface modification of materials using strong laser-induced shock waves. This technology uses a short pulse (<10ns), high peak power density (>1GW / cm2) laser to pass through a transparent confinement layer and act on the absorber layer coated or attached to the surface of the workpiece. The absorption layer absorbs the laser energy and expands rapidly to generate a GPa-level shock wave, which propagates into the material, increases the dislocation density on the surface of the material, refines the grains, and forms residual compressive stress, thereby improving the material's anti-fatigue and anti-corrosion properties. At present, laser shock strengthening technology has been widely used in aviation, shipbuilding, mechanical e...
