Abstract

The invention relates to a temperature measurement and control device for additive manufacturing, which belongs to the technical field of temperature measurement and control, and includes a first temperature detector, a first temperature regulator, a second temperature detector, a second temperature regulator, a data memory, and a main controller; The main controller is respectively connected with the first temperature detector, the first temperature regulator, the second temperature detector, the second temperature regulator and the data memory. In the present invention, on the basis of the existing surfacing welding, it is combined with stirring and welding; that is, the combination of the argon arc welding nozzle and the stirring head can make the composition of the surfacing layer uniform; and, on this basis, through the first temperature detector , the cooperation of the first temperature regulator, the second temperature detector and the second temperature regulator, real-time measurement and control of the temperature of surfacing and stirring, to ensure the standard operating temperature of the two, and further improve the forming accuracy; to ensure additive manufacturing safe and reliable operation of the equipment.

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...
