Abstract
The invention discloses an intelligent water-cooled arc additive manufacturing device and method for reducing the heat accumulation of stacked layers. The device includes four parts: a stacking system, a sensing system, a control system, and a water cooling system. The water cooling system makes the cooling water continuously flow through the side of the accumulation layer and take away most of the heat, quickly reducing the temperature of the accumulation layer; the sensor system collects the temperature information and water level information in the water cooling system in real time through the temperature sensor and the water level sensor; The information collected by the sensor system automatically controls the water level and temperature in the water cooling system. Based on the arc additive manufacturing method of the device, the problem of serious heat accumulation in the accumulation layer caused by the accumulation process of metal components is effectively solved by circulating cooling water at a constant temperature. , greatly improving the forming efficiency and forming quality of the arc additive manufacturing method, and refining the grain of the metal component structure.
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...
