Abstract

The invention discloses a metal thin strip three-dimensional forming system based on piezoelectric coupling control. Comprising a Joule thermal power source, an angle-adjustable printing mechanism mounting device, a hammering type printing mechanism, a rolling type printing mechanism, pressure sensors, a substrate, a control system and a metal thin strip conveying mechanism, wherein the hammering type printing mechanism and the rolling type printing mechanism are mounted on the angle-adjustable printing mechanism mounting device in an array mode, and the pressure sensors are mounted on the hammering type printing mechanism and the rolling type printing mechanism. A first pole of the Joule thermal power supply is electrically connected with the hammering type printing mechanism and the rolling type printing mechanism, a second pole of the Joule thermal power supply is electrically connected with the substrate, and the Joule thermal power supply and the pressure sensor are both connected with the control system; the pressure sensor is used for collecting the contact pressure between the hammering type printing mechanism and the metal thin strip on the base plate and between the rolling type printing mechanism and the metal thin strip on the base plate; and the control system is used for controlling the Joule thermal power supply to output Joule thermal energy according to the magnitude relationship between the contact pressure and a preset trigger pressure threshold value. The printing efficiency of the system is improved, and the requirements for different printing modes are met.

Description

technical field [0001] The invention relates to the field of metal additive manufacturing, in particular to a three-dimensional forming system for thin metal strips based on piezoelectric coupling control. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, integrates computer-aided design, material processing and molding technology, and is based on digital model files. Through software and numerical control systems, various materials are processed according to extrusion, sintering, melting, Photocuring, spraying, etc. are accumulated layer by layer to create a manufacturing technology for physical objects. Compared with the traditional processing mode of raw material removal-cutting and assembly, it is a "bottom-up" manufacturing method through material accumulation, starting from scratch. This makes it possible to manufacture complex structural parts that were restricted by traditional manufacturing methods in the past. [0003] The ...
