Problems solved by technology

However, the polyurethane rubber mold is an elastic material. After the shock wave is unloaded, the deformation will completely rebound. Because it is closely attached to the workpiece that has been formed, it will force the workpiece to partially recover and affect the accuracy of the workpiece.

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the drawings.

[0027] The structure of the laser mask impact forming device based on the plasticine mold of the present invention is as follows figure 1 Shown, including laser loading system, platform moving system, forming system, control system connection. The laser loading system consists of a nanosecond laser 11, a reflector 10, and a focusing lens 9. The laser beam emitted by the nanosecond laser passes through the reflector 10 and the focusing lens 9 and directly enters the forming system; the forming system includes a ring press block 8, a mask 7. Optical medium 6, absorption layer film 5, work piece 4 and plasticine 3, the forming system is placed on the platform moving system through the ring pressing block 8; the platform moving system is composed of the three-dimensional moving platform 2 and the L-shaped base 1; the three-dimensional moving platform 2 is fixed on the L-shaped b...

Abstract

The invention discloses a laser mask shock forming device based on a plasticine mould and a method of the laser mask shock forming device. The device comprises a laser loading system, a platform moving system, a forming system and a control system, the forming system comprises plasticine serving as a mould, a workpiece, an absorbing layer film, an optical medium, a mask and an annular pressing block, the workpiece is arranged on the plasticine, the transparent optical medium serving as a restraint layer is attached to the upper side of the workpiece in a pressing manner, the absorbing layer film is arranged between the optical medium and the workpiece, the mask for changing the size and the shape of a laser spot is arranged above the optical medium, the annular pressing block is arranged above the mask, and the mask, the optical medium, the absorbing layer film, the workpiece and the plasticine are fastened on the platform moving system through the annular pressing block. The device is low in cost, rapid, precise and repeatable and can be used for laser mask shock forming of conventional difficultly formed materials based on the plasticine mould, mould designing and manufacturing expenses can be reduced, and machining precision and working efficiency are improved.

Description

Technical field [0001] The invention belongs to micro-electromechanical system (MEMS) processing technology and laser micro-processing technology, and specifically relates to a plasticine mold-based laser mask impact forming method and device thereof, and is particularly suitable for the field of microplastic forming of micro metal foils. Background technique [0002] There are many plastic forming methods for sheet metal, including stamping, shot peening, and explosive forming. The most common is the production of various metal parts by stamping. The disadvantages are high mold costs and long production cycles. At the same time, due to factors such as stress conditions, the forming limit is limited, and the surface strength after forming is usually reduced. Shot peening is the use of pellets to impact the surface of the material at high speed to cause plastic deformation, which can form residual compressive stress on the surface of the material, thereby improving the fatigue res...
