Abstract

The invention relates to an additive manufacturing temperature measurement and control device, and belongs to the technical field of temperature measurement and control. The additive manufacturing temperature measurement and control device comprises a first temperature detector, a first temperature regulator, a second temperature detector, a second temperature regulator, a data storage device and a main controller, wherein the main controller is connected with the first temperature detector, the first temperature regulator, the second temperature detector, the second temperature regulator and the data storage device. According to the additive manufacturing temperature measurement and control device, on the basis of existing surfacing, stirring and welding are combined, that is, an argon arc welding nozzle and a stirring head are combined, so that components of a surfacing layer are uniform; and on the basis, the first temperature detector, the first temperature regulator, the second temperature detector and the second temperature regulator are matched, so that the surfacing temperature and the stirring temperature are measured and controlled in real time, the standard operation temperature of surfacing and stirring is guaranteed, and the forming precision is further improved; and safe and reliable operation of additive manufacturing equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement and control, and in particular relates to a temperature measurement and control device, system and method for additive manufacturing. Background technique [0002] The wire feeding additive manufacturing technology (WAAM) uses welding arc as the heat source to melt the metal wire, and accumulates each layer on the substrate according to the set forming path, until the metal parts are formed. Compared with various additive manufacturing technologies using powder raw materials, WAAM has higher material utilization rate, high molding efficiency, low equipment cost, and basically unlimited size of molded parts. Arc additive manufacturing technology uses layer-by-layer surfacing to manufacture dense metal solid components. Because the arc is used as the energy beam, the heat input is high and the forming speed is fast. It is suitable for low-cost, efficient and rapid near-net forming of...
