Method and apparatus for preparing and forming minitype compound material

Abstract

The invention relates to a method and a device for preparing and forming a micro composite material. The device consists of an Nd:YAG laser, a reflector, a lens, a restraint layer, a single-dimension mobile platform, a micro die, a three-dimension mobile worktable, a three-dimension mobile platform controller, an L-shaped base and a computer. The method for the synchronous realization of material composite and micro forming comprises: pulsed laser is used for driving a metal foil plate to move at high speed; the metal foil plate impacts a base foil plate in the micro die at high speed after moving a certain distance; the high temperature and high pressure generated in the impact surface can realize the composite connection between the metal foil plate and the base foil plate; the connected metal foil plate and base foil plate have certain impulse and compress to the direction of the die; owing to the limitation of the die, the shape of the micro die can be duplicated, thus realizing the synchronization of composite material production and micro forming. The method and the device have the advantages of reasonable design, simple process, good consistency, and being applicable to mass production.

Description

technical field [0001] The invention relates to the field of composite material manufacturing and micro-forming, in particular to a method and device for preparing and forming micro-composite materials, which can simultaneously realize the production and micro-forming of composite materials, and is suitable for batch production and forming of composite materials. Background technique [0002] Composite material refers to a material composed of two or more different substances combined in different ways. It can give full play to the advantages of various materials, overcome the defects of a single material, and expand the application range of materials. Because composite materials have the characteristics of light weight, high strength, excellent elasticity, chemical corrosion resistance and weather resistance, they are widely used in aerospace, electronics and electrical fields. [0003] Explosive welding is a process for manufacturing composite materials. It has incomparabl...

AI Technical Summary

Problems solved by technology

However, the biggest difference between microplastic forming and traditional plastic forming is that when the size of the workpiece reaches the submillimeter or micron scale, the physical properties and internal structure of the workpiece itself change, showing a scale effect, making the deformed material show brittleness, It is prone to plastic failure; the scale effect also increases the ratio of the surface area to the volume of the material. The impact of friction on the forming is much greater than that of the macroscopic size, which affects the plastic forming ability of the material. The key to forming technology

[0006] According to the above, it can be concluded that plastic micro-forming can realize mass production at low cost, but the forming capacity is low; explosive welding can realize the production of composite materials, but it has the disadvantages of low processing accuracy, large pollution, and inability to realize miniaturization. A method that can simultaneously realize the production and micro-forming of composite materials will be widely used in industrial production
