Embodiment Construction
[0020] In order to express the forming characteristics of the present invention more clearly, an example of a metal composite part composed of two metals A and B is listed below, but it is not a limitation of the present invention. If those skilled in the art are inspired by it, Without departing from the inventive purpose of the present invention, other embodiments shall fall within the protection scope of the present invention.
[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0022] Use CAD software to build a three-dimensional model of the part, and add the material information of the part to the model. According to the external shape of the part, the mold of the part is made with coated sand.
[0023] The CAD model is layered in the height direction, combined with the material information of each layer, and the scanning path of each layer is generated by a computer; the A and B metal...

The invention discloses a forming method of a metal composite part, which is organic combination of a metal spraying, stacking and forming technology and a conventional casting process and belongs to a material increase manufacturing technology in the field of machine manufacturing. The forming method comprises the following specific steps: building a three-dimensional model of a preformed metal composite part by using CAD software, increasing material information and manufacturing a mold of the part according to the shape of the part; layering the three-dimensional model of the part in the height direction to obtain a scanning path of each layer; heating metal by a heating device and melting the metal into liquid; spraying, stacking and forming a plurality of metal solutions layer by layer according to the scanning paths including the material information; cooling the part after finishing forming, and taking down the mold to obtain a final metal composite part. The forming method can be used for directly manufacturing metal composite parts being complex in shape and high in size accuracy.
Description
Technical field [0001] The invention belongs to the field of additive manufacturing of mechanical manufacturing, and specifically provides a method for forming metal composite material parts. Background technique [0002] Metal composite materials can greatly improve the mechanical properties of single metal materials, and are widely used in petroleum, chemical, shipbuilding, machinery manufacturing, power, water conservancy and food industries. The production methods of metal composite materials at home and abroad mainly include solid-liquid phase bonding method, solid phase bonding method, laminated hot rolling method, diffusion crimping method, etc. Among them, explosive welding and hot rolling are the most mature and widely used. And the production of titanium-steel composite panels. [0003] At this stage, the production process of metal composite materials has extremely high requirements on the surrounding environment, and there are often defects such as cracks and delaminat...
