Problems solved by technology
[0006] The first molding method, the method of filling the cavity through additive manufacturing to obtain a frame structure and a closed structure needs to consume more metal raw materials, which increases the cost of raw materials while increasing the cost of time
More tools and processing time are required for later machining
Significantly increases the cost of additively manufacturing such parts, making them less competitive
[0007]The second forming method is to obtain frame structure and closed structure parts through post-welding combination, and the overall process is relatively complicated
For parts with complex structures or thicker welding grooves, the welding process is greatly restricted

The embodiment of the invention discloses a method for manufacturing a metal closed structure. The method comprises the following steps that 101, structural characteristics of the metal closed structure are acquired; 102, module division is carried out on the metal closed structure based on the structural characteristics; 103, stacking is carried out to form a main body region through an electron beam fuse process; 104, a first filling layer is formed on one end surface of the main body region through the electron beam fuse process; 105, the posture of the main body region is converted, and a second filling layer is formed on the other end surface of the main body region through the electron beam fuse process; 106, steps 104 and 105 are alternately executed until a closed region corresponding to a closed machining region is formed on the end surface of the main body region; and 107, a filling part is filled to prepare and acquire the metal closed structure. According to the method for manufacturing the metal closed structure, waste of raw materials can be reduced, and meanwhile, welding is not needed when the metal closed structure is prepared so that the mechanical strength of the metal closed structure can be improved, and the product quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of metal processing, in particular to a method for manufacturing a metal closed structure. Background technique [0002] Electron beam fuse deposition rapid manufacturing technology is a new additive manufacturing technology developed in recent years. Like other rapid prototyping techniques, the 3D CAD model of the part needs to be layered and the machining path generated. The high-energy electron beam is used as the heat source to melt and feed the metal wire, which is piled up layer by layer according to the predetermined path, and forms a metallurgical bond with the previous layer until a dense metal part is formed. This technology has the characteristics of fast forming speed, high degree of freedom in part design, good protection effect, high material utilization rate, high energy conversion rate, etc. It is suitable for the forming and structure of active metal parts such as large and medium-sized tit...
