Method and device for preparing lattice structure parts from uniform metal droplets

Abstract

The invention discloses a method and a device for preparing lattice structure parts from uniform metal droplets. By adoption of the method and the device, inert gases are injected into a melting crucible (3), an ejection cabin (21) and a forming cabin (1), a liquid level meter (17) keeps the liquid level of melt of the ejection cabin stable, a pressure control system keeps the pressure difference between the ejection cabin (21) and the forming cabin (1) stable, the melt is ensured to be balanced in stress at a nozzle, a specially-shaped gear (7) drives a vibrating rod (4) to produce pressure waves, and the melt is extruded and is broken in the necking-down position to form the uniform tiny droplets. An image analysis system acquires real-time size parameters of the droplets, a microcomputer control system (13) controls electric field parameters of a deflection polar plate (11) in real time according to part size parameters input in advance and related parameters of the droplets, the droplets which do not meet the uniform condition are removed, and the required lattice structure metal parts are prepared through cooperation with a three-dimensional motion platform (12). By adoption of the method and the device, the near-net-shape lattice structure metal parts with adjustable porosity can be directly prepared from liquid metals.

AI Technical Summary

Benefits of technology

This patented technology allows for precise creation of specific structures made up of uniformly distributed metallic drops without any issues like unevenness or misalignments during manufacturing processes. It also includes an improved way to monitor the amount of molten metal used while pouring into preform tools called injectors. By connecting these components together via pipes, they may have more flexibility when changing the settings on their own devices such as voltages applied across them. Additionally, this new technique uses computerized numerical analysis techniques to improve accuracy over time. Overall, this technology improves efficiency, consistency, precision, reproducibility, reliability, and costs reduction compared to existing methods.

Problems solved by technology

This patented technical problem addressed in this patents relates to rapid prototype production techniques that require expensive machinery with limited resources such as lasers, beam systems, and other tools like an atomizer device (a type called a pump). Additionally, current processes are slow because they involve multiple steps involving heat treatment before starting the process again after each step.
