Temperature controlling system and method for additive manufacturing

Abstract

The invention relates to a temperature controlling system and method for additive manufacturing. The temperature controlling system comprises a fused cladding device, a micro-forging device, a detection device, a controlling module and an adjustment device, wherein the fused cladding device is used for fusing materials to form a fused cladding layer; the fused cladding device comprises a first energy source which is configured to enable energy beams to point to the materials so as to fuse at least a part of materials and form the fused cladding layer; the micro-forging device is coupled with the fused cladding device and is used for forging the fused cladding layer; the detection device is used for detecting first internal effect parameters of a forging position of the fused cladding layerunder a forging effect of the micro-forging device; the control module is used for receiving the first internal effect parameters detected by the detection device and calculating a first calculationtemperature value of the forging position based on the first internal effect parameters; and the adjustment device is coupled with at least one of the first energy source and the micro-forging device,and is used for receiving the first calculation temperature value and adjusting at least one of the first energy source and the micro-forging device to ensure that the first calculation temperature value is located in an expected temperature range when the first calculation temperature value of the forging position is not located in the expected temperature range.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a temperature control system and method for additive manufacturing. Background technique [0002] Additive manufacturing technology is a rapidly developing emerging technology for material processing. The current mainstream additive manufacturing usually realizes the metallurgical bonding of metal materials through the "melting-solidification" method, which is characterized by using high-energy beams such as laser beams, electron beams, and arc beams as heat sources to melt synchronously fed metal materials. , such as metal powder, metal wire, etc., are piled up layer by layer, and the parts are manufactured by surfacing welding. The internal microstructure of the parts produced is solidified structure. [0003] Compared with the traditional forging structure, the crystal grains in the solidification structure obtained by the above-mentioned "melting-solidificatio...
