Abstract

The surface temperature measuring device and its measuring method for electron beam fuse additive manufacturing parts described in the present invention can detect the surface temperature of formed parts more simply and conveniently, so as to avoid splashing and stacking height when measuring the surface temperature. , the influence of workbench movement; The measurement method of the present invention is contact temperature measurement, can measure the temperature of forming surface; Metal vapor protection baffle can prevent the pollution of metal vapor to thermocouple, prevent metal vapor from contaminating the baffle at the same time The pollution of the hinge makes the device effective for a long time; the thermocouple is fed with springs and pressure-sensitive components, which can effectively prevent the hard collision between the thermocouple and the forming substrate, prolong the service life and increase the control means; the device can be used together with the processing program to control the forming The temperature field tends to be consistent, making the forming process more stable, and greatly improving the appearance quality, internal structure and performance of the forming.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a surface temperature measuring device for an electron beam fuse additive manufacturing part and a measuring method thereof. Background technique [0002] Electron beam fuse deposition forming technology is an emerging additive manufacturing technology developed in recent years. As with other additive manufacturing techniques, a 3D CAD model of the part needs to be layered and a machining path generated. In a vacuum environment, the high-energy electron beam is used as a heat source to melt and feed the metal wire, which is stacked layer by layer according to a predetermined path, and forms a metallurgical bond with the previous layer until a dense metal part is formed. This technology has the characteristics of fast forming speed, high degree of freedom in parts design, good protection effect, high material utilization rate and high energy conversion rate. It is ...
