Abstract

The invention discloses a device and method of intelligent water-cooled wire arc additive manufacture for reducing the heat accumulation in a stack layer. The device comprises four parts: a stack system, a sensing system, a control system and a water cooling system. During the process of the wire arc additive manufacture, through the water cooling system, the cooling water continuously flows through the side of the stack layer, and most of the heat is taken away, so that the temperature of the stack layer is quickly reduced; the sensing system collects temperature information and water level information in the water cooling system in real time through a temperature sensor and a water level sensor; the computer control system automatically controls the water level and temperature in the water cooling system through the information collected by the sensing system, the method based on the device effectively solves the problem of severe heat accumulation in the stack layer during the stacking process of metal components by using the mode of circulating cooling water with constant temperature, greatly improves the forming efficiency and forming quality of the wire arc additive manufacture method, and refines the grains of the metal component tissue.

Description

technical field [0001] The invention belongs to the technical field of arc additive manufacturing, and in particular relates to an intelligent water-cooled arc additive manufacturing device and method for reducing heat accumulation in a stacked layer. Background technique [0002] As a low-cost and high-efficiency metal additive manufacturing method, arc additive manufacturing is of great significance in promoting the development of metal additive manufacturing technology to civilian use and scale. However, arc additive manufacturing faces a serious problem of heat accumulation in the build-up layer during the manufacturing process of metal components, which restricts the practical application of this technology. [0003] The electric arc additive manufacturing technology uses metal wire as the raw material, melts the wire through the arc as the heat source, and accumulates metal components layer by layer on the substrate from bottom to top. During the stacking process of m...
