Problems solved by technology

The use of high molecular polymers that have gained kinetic energy as flexible punches to form workpieces will not affect the surface quality of workpieces, but high molecular polymers are elastic materials that will rebound after forming workpieces, which cannot ensure that the formed workpieces are completely attached to the surface of the mold. Workpiece accuracy

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The present invention is based on the structure of the precision micro-forming device of the laser continuous stamping plasticine technology such as figure 1 As shown, it is composed of laser loading system, plastic forming system and computer control system. The laser loading system consists of a nanosecond laser 7, a reflector 6, and a focusing lens 5. The laser beam emitted by the nanosecond laser passes through the reflector 6 and the focusing lens 5 and then enters the plastic forming system; the plastic forming system consists of a sample system 4, a clamping Specifically 3. The three-dimensional mobile platform 2 and the L-shaped base 1 are composed. The three-dimensional mobile platform 2 is fixed on the L-shaped base 1. The sample system 4 is fixed by the clamp body fastened on the top of the three-dimensional mobile platform 2; the computer c...

Abstract

The invention discloses a precise micro-forming device and a method thereof based on a laser continuous stamping plasticine technology. The device comprises a laser loading system, a plastic forming system and a computer control system. The laser loading system comprises a nanosecond laser, a reflection mirror and a focusing lens. The plastic forming system comprises a sample system, a clamp body, a three-dimensional moving platform and a base. The computer control system comprises a three-dimensional moving platform controller, a laser controller and a computer. According to the device and the method, plasticine is used for transmitting impact force, in a multi-time impact process, the plasticine and a workpiece are attached together gradually, stress on the workpiece is even, scratching cannot happen, surface quality of the workpiece is improved, and meanwhile according to the characteristic that the plasticine deforms in an plastic mode after being stressed, the workpiece and a micro mould can be attached with each other, rebounding of the workpiece is avoided, and forming precision of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to a precision micro-forming device and method for laser continuous stamping plasticine technology, and belongs to the technical field of laser processing and manufacturing and micro-plastic forming. Background technique [0002] Laser shock technology is a processing method with good prospects. Its principle is that the shock wave induced by high-energy short-pulse laser interacts with the material, and the shock wave generated by the interaction between the strong laser and the material is used to improve the mechanical properties of the material, especially the fatigue. life. This technology has been widely used in mechanical engineering, aerospace, microelectronics, military and other industries. Currently, this technology is mainly used in material modification, metal impact strengthening and forming, and non-destructive testing. In recent years, the rapid development of laser processing technology in the application of micr...
