Abstract

The invention discloses a surface temperature measuring device for an electron beam fuse wire additive manufacturing part and a measuring method of the surface temperature measuring device. The surface temperature of the formed part can be detected more simply and conveniently, so that the measuring operation is prevented from being influenced by splashing, stacking height and the movement of a workbench during a surface temperature measuring process. The measuring method is contact type temperature measurement, and the temperature of the forming surface can be measured; a metal steam protection baffle can prevent metal steam from polluting a temperature measuring couple and prevent metal steam from polluting a baffle hinge, so that the device can be effective for a long time; a spring anda pressure-sensitive element are fed into the temperature measuring couple, so that hard collision between a thermocouple and a formed base body is effectively prevented, the service life is prolonged, and control means are increased; and the device can control a forming temperature field to tend to be consistent together with a machining program, so that the forming process is more stable, and the forming appearance quality and the internal structure and performance are greatly improved.

Description

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