Embodiment Construction

[0026] Combine below figure 1 The details and working conditions of the specific device proposed by the present invention are described in detail.

[0027] The device consists of 13 parts. The computer 12 controls the laser controller 10, and the laser controller 10 adjusts the laser parameters emitted by the nanosecond laser 11 according to actual conditions. The laser light emitted by the nanosecond laser 11 is sequentially transmitted to the total mirror 7 and the lens 6 via the laser beam 9 and finally to the sample body 5 below the lens 6. The sample body 5 is placed in the clamp 4, and the clamp 4 is installed on the vertical moving platform 3. The horizontal movement platform 2 and the vertical movement platform 3 are installed on the L-shaped base 1, and the displacement adjustment of the horizontal movement platform 2 and the vertical movement platform 3 is controlled by the movement platform controller 13 controlled by the computer 12. The specific process of implemen...

Abstract

The invention discloses a laser direct-compounding micro-plastic forming device and method, belonging to the technical field of parts of a laser processing micro-electromechanical system (MEMS). The device comprises a laser loading system, a forming system and a control system. The method comprises the following steps: laser penetrates through a restraint layer after being focused by lens and acts on an energy-absorbing layer; the energy-absorbing layer absorbs the laser energy; a high pressure and high temperature plasmasphere is formed in a very short period of time and sprayed outward quickly; the expanded plasmas are limited by the restraint layer, so that the plasma pressure increases quickly and causes impact loading on a workpiece; the workpiece is extruded between the restraint layer and a compound micro-mould, so that the workpiece generates plastic deformation and copies the appearance of the compound micro-mould; and a compound process of stretching, punching and trimming atarget workpiece is realized in one impact forming process by a stretching female mould, a trimming female mould and a punching male mould which are arrayed on the compound micro-mould, and simultaneously workpieces can be formed in batch.

Description

Technical field [0001] The invention belongs to the technical field of laser processing micro-electromechanical system (MEMS) parts, and particularly refers to a laser micro-forming method and device. Background of the invention [0002] In recent years, with the gradual rise of micro-nano technology and the continuous development of the miniaturization trend in electronic products, micro-mechanical technology with its own small shape and size or small size of operation has become a high-tech way for people to understand the microscopic field and transform the objective world. technology. Especially with the continuous progress of society and the increasing improvement of people’s living standards, people’s requirements for daily life products are becoming more intelligent, miniaturized, multi-functional integration, etc. This makes the process of designing and manufacturing products fully consider To the above functional requirements. [0003] With the development of product min...
