Abstract

The invention discloses a laser impact micro-forming device based on hydraulic oil and a method of the laser impact micro-forming device. The laser impact micro-forming device comprises a laser emission system, a control system and a workpiece deformation operating system; the laser emission system comprises a pulse laser, a plane reflecting mirror, a pancratic lens and a lens holder; the controlsystem comprises a laser controller, a computer, a three-dimensional moving platform controller, a pneumatic controller, a hydraulic controller and an electromagnetic controller; and the workpiece deformation operating system comprises a three-dimensional moving platform, a housing, a feeding device, a sleeve, a soft film and a limiting layer pressing device. According to the method, by taking a laser pulse as an energy source and employing the soft film to compress the hydraulic oil to generate impact pressure, micro-forming of a thin plate is realized, and the forming effect of a corner micro chamfer can be better. The feeding device can achieve the effect of changing a workpiece in a semi-automatic manner, and can conveniently achieve the effects of locating and clamping the workpiece.

Description

technical field [0001] The invention belongs to the technical field of laser shock plate micro-forming, in particular to a laser shock micro-forming device and method based on hydraulic oil. Background technique [0002] In recent years, with the rapid development of micro-electromechanical systems (MEMS), the demand for micro-products with light, thin, short, small, and multi-functional characteristics has been increasing, which has led to the development of metal micro-forming technology, and the miniaturization of products has also It has become an important trend in the development of industrial manufacturing. Micro-device manufacturing has problems such as low efficiency, high cost, difficult operation, and material limitations. Therefore, it has become the consensus of researchers to develop and explore new micro-forming processes. At present, micro-punches are often used to impact plates in micro-plastic forming, but the difficulty in manufacturing punching equipment...
