Title: COMBINING DEVICE FOR LASER HEATING POWER LAYER-BY-LAYER INTERACTION ADDITIVE MANUFACTURING
Abstract:
Disclosed is a combining device for laser heating power layer-by-layer interaction additive manufacturing, wherein the combining device comprises a laser shock strengthening module (1), a water spraying module (2), a selective laser melting module (3), a waterproof layer applying module formed by a waterproof layer (4), a roller (5), a roller bracket (6), a threaded spindle (7) and an electric motor, a "回"-shaped tank (8), a pneumatic module (9) composed of an air compressor, a cylinder and a control valve, a base (10), a hydraulic lifting module (11) formed by a hydraulic cylinder, an electrical system and a lifting working table (12), a guide rail (15) and a powder laying module (16) formed by a powder feeding box, a scraper and the electric motor. By means of the alternative operation of the laser shock strengthening module (1) and the selective laser melting module (3), laser shock strengthening simultaneously carried out on a formed part (13) in the forming process of the formed part (13) is achieved by the device, and the strengthening effect on the formed part (13) is more thorough, thereby effectively solving the problem of "shape control" of the formed part (13) which is prone to deformation and cracking caused by internal stress in additive manufacturing and the problem of "property control" of a poor fatigue performance caused by metallurgical defects, improving the fatigue strength and mechanical properties of the formed part (13), and realizing high-efficiency and high-quality integrated machining of the formed part (13).
