Problems solved by technology

[0002] The requirements for the development cycle of the new generation of weapons and equipment are gradually increasing, and most of the structural parts are double-sided asymmetric deep cavity structures or variable cross-section structures. Traditional casting and other technologies are difficult to adapt to the rapid response to structural iterative design.

Abstract

The invention relates to a forming method of a complex structural part, and belongs to the technical field of precision forming machining. The complex structural part is of an equal-cross-section structure with a transverse rib or a boss (except for the transverse rib or the boss, the other portion is of the equal-cross-section structure), or is of a double-side asymmetric deep cavity structure with a web plate. The composite manufacturing method of combining the arc additive and hot extrusion makes full use of the characteristics of high efficiency and low cost of the hot extrusion and arc additive manufacturing technology, so that the defect that the arc additive method and the hot extrusion method can only form a relatively simple structural part is avoided, and rapid and efficient manufacturing of the complex structural part is realized; and secondly, the mechanism based on the fact that the melting depth can be increased by an active agent is utilized to coat a region needs to undergo arc additive manufacturing on an extrusion substrate with a layer of active agent, so that the connecting performance of an interface is further improved, and the high-performance manufacturing of the complex structural part is realized.

Description

technical field [0001] The invention relates to a forming method of a complex structural part, which belongs to the technical field of precision forming. The complex structural part is an equal-section structure with transverse ribs or bosses (except the transverse ribs or bosses, others are equal-sectional structures) Or a bilateral asymmetric deep cavity structure with webs. Background technique [0002] The requirements for the development cycle of the new generation of weapons and equipment are gradually increasing, and most of the structural parts are double-sided asymmetric deep cavity structures or variable cross-section structures. Traditional casting and other technologies are difficult to adapt to the rapid response to structural iterative design. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the deficiencies in the prior art and propose a method for forming complex structural parts, which is used to form ...
