Problems solved by technology

However, this technology also has obvious limitations: First, compared with conventional manufacturing methods, its manufacturing cost is high and processing efficiency is low, so it can only be used to manufacture metal components that are difficult to adopt conventional methods and spare no expense in cost; Secondly, it must be made of metal powder, and there are strict requirements on the particle size of the powder
[0007] But there is no device capable of realizing the mobile micro-die-casting forming method of metal components at present. Therefore, the purpose of the present invention is to provide a device capable of realizing the mobile micro-die-casting forming method of metal components

Abstract

The invention relates to a device capable of directly forming metal components by moving micro-die-casting melt, including an image acquisition device, an environment box, a three-dimensional motion table, a melting furnace, a precision casting furnace and an adjustable pressure device. The device of the present invention has a compact structure, and can adjust the structure of the component material point by point and layer by layer (including grain size) , phase composition and interface structure, etc.), residual stress state (including size and distribution) and surface quality. The invention can not only shape the metal component according to the set shape and size, but also can effectively control its mechanical properties, and can accurately realize the mobile micro-die casting of the metal component directly formed by the melt.

Description

technical field [0001] The invention relates to the field of material processing equipment, in particular to a device for realizing mobile micro-die-casting of metal components. Background technique [0002] In recent years, laser three-dimensional forming technology has made important progress in the direct manufacture and engineering application of large-scale thin-walled titanium alloy components. However, this technology also has obvious limitations: First, compared with conventional manufacturing methods, its manufacturing cost is high and its processing efficiency is low, so it can only be used to manufacture metal components that are difficult to adopt conventional methods and spare no expense in cost; Secondly, it must be made of metal powder, and there are strict requirements on the particle size of the powder. If it is too fine, the particles are easy to be burned, which will reduce the utilization rate of the powder. If it is too large, the particles may not be ...
