Metal material processing system

Abstract

A metal material processing system comprises a visible light camera, an infrared camera, a light-emitting diode, a deposition platform, a computer, a piezoelectric driver, a nozzle, an induction heating coil, a piezoelectric tube, an injector, a metal powder box and a switch valve, wherein the liquid level in the piezoelectric tube reflects the pressure applied to metal powder, and after the metal powder in the piezoelectric tube enters the nozzle, liquid drops are formed under the action of the induction heating coil and drop to an interface on the deposition platform; the computer collects the temperature of the liquid drops through the infrared camera and controls the induction heating coil to heat the nozzle so that the metal powder can be changed into metal liquid, and the computer controls the propelling pressure of the injector; the visible light camera captures an image jetted by the nozzle, and the computer performs image processing and analysis based on the jetted image; and dynamic liquid drop behaviors are obtained accordingly from a series of images.

Description

technical field [0001] The invention belongs to the processing field, and particularly relates to a metal material processing system. Background technique [0002] Deposition processing using molten metals enables the construction of complex objects with a wide variety of materials and functions, opening enormous opportunities for a wide range of applications including the aerospace, automotive, defense and biomedical industries. There are many problems in the current deposition processing of most metal materials: (1) During the layer-by-layer deposition process, if the process deviation is not corrected in time, the defects will propagate to the subsequent layers, thus affecting the functional integrity of the part (fatigue characteristics, strength characteristics, (2) Due to the solidification morphology of metal droplets and the step effect, parts deposited by metal droplets usually have a rough surface, which is not conducive to large-scale commercialization. The surfa...

Problems solved by technology

There are many problems in the current deposition processing of most metal materials: (1) During the layer-by-layer deposition process, if the process deviation is not corrected in time, the defects will propagate to the subsequent layers, thereby affecting the functional integrity of the part (fatigue properties, strength properties, geometric integrity) lead to low reliability and low quality, which is not conducive to its large-scale commercialization; (2) due to the solidification form of metal droplets and the step effect, parts deposited by metal droplets usually have rough surfaces, while rough The surface barrier technology is used to manufacture parts with high-quality surface finish requirements, especially some microwave devices, such as waveguides and horn antennas, which require smooth inner surfaces to ensure the propagation of electromagnetic waves; (3) in order to be able to control droplets generation requires very precise measurement and control of jetting properties, such as droplet velocity and droplet volume, and precise droplet capture is currently lacking
