Additive and subtractive composite manufacturing equipment for large format parts

Abstract

The invention discloses a material increase and decrease composite manufacturing device of large-breadth parts. The device comprises a lathe bed, wherein a plurality of six-degree-of-freedom inverted hanging robots used for material increase manufacturing and a five-axis linkage planer type milling machine are mounted on the lathe bed; the plurality of inverted hanging robots are distributed around a milling head of the planer type milling machine; material increase manufacturing devices are arranged on the inverted hanging robots; a utilized heat source can be high-power laser beams or electric arcs; the material increase manufacturing devices perform manufacturing of single-layer or multi-layer blank bodies on a working platform; and the milling head of the planer type milling machine performs finish machining and trimming on the single-layer or multi-layer blank bodies. According to the material increase and decrease composite manufacturing device, the difficulty of milling and processing of the large-breadth complex parts and defects of a material increase manufacturing technology in the aspects like size and shape are overcome; the material increase manufacturing technology and a material decrease manufacturing technology can be independently carried out and can be carried out at the same time in different regions as well; and the integration of the device is high, the cooperative control is convenient to operate, and the integrated, quick, efficient and precise forming of the large-breadth and super large-breadth complex parts can be achieved.

Description

technical field [0001] The invention relates to the technical field of additive and subtractive material composite manufacturing equipment, in particular to a plurality of electric arc additive or laser melting deposition additive and gantry milling composite manufacturing large-format complex component equipment. Background technique [0002] Arc additive manufacturing is to use arc heat source to melt metal wire, and form metal parts according to the principle of layer-by-layer accumulation of discrete materials. Laser melting deposition additive manufacturing is the application of high-power laser beams to melt metal powder, and it is also based on the principle of layer-by-layer accumulation of discrete materials to form metal parts. [0003] Compared with traditional manufacturing, additive manufacturing technology is a process in which materials are added point by point, line and surface to realize the accumulation and forming of complex parts. Compared with other met...
