Added material manufacturing device and method

Abstract

The invention provides an added material manufacturing device and a method. The device is characterized by comprising an added material machining part, a high-speed camera part, an infrared temperature measuring part, an optical measuring part, an internal defect detecting part, an aftertreatment part and a control part, wherein the high-speed camera part comprises a camera head, which moves withthe added material machining head at the same time to obtain material image information; the infrared temperature measuring part comprises a temperature measuring head, which moves with the added material machining head at the same time to obtain material temperature distribution information; the optical measuring part detects surface defects and forming sizes of materials to obtain detecting information; the internal defect detecting part comprises a detecting head and a detecting analyzer; the aftertreatment part treats material defect areas to eliminate defects by adopting corresponding aftertreatment modes; the aftertreatment modes comprise at least one of mechanical rolling treatment, laser shock reinforcement treatment and friction stir treatment; and the control part controls all the parts to operate to obtain various information, determines the defect treatment areas, aftertreatment paths and the aftertreatment modes based on the information, and controls the aftertreatment part to perform corresponding aftertreatments.

Description

technical field [0001] The invention belongs to the field of additive manufacturing of metal materials, and in particular relates to an additive manufacturing device and a method for additive manufacturing using the device. Background technique [0002] Additive manufacturing technology is based on the three-dimensional model of the product and uses the principle of discrete stacking to realize rapid prototyping manufacturing technology. It can directly manufacture complex parts of various materials and has a wide range of industrial application prospects. However, additive manufacturing has the characteristics of high molten pool temperature, rapid solidification, and large temperature gradient, which will lead to high residual stress and metallurgical defects inside the formed workpiece, resulting in deformation, reducing mechanical properties, especially fatigue properties, and affecting Use performance. The above phenomenon is particularly prominent in the manufacturing...
