Abstract

The invention discloses a high-performance alloy steel solid-phase additive forming device and process based on induction heating compensation. The high-performance alloy steel solid-phase additive forming device and process are mainly used for solid-phase additive manufacturing of high-performance alloy steel and other metal material parts which are high in melting point and difficult to deform. The device comprises a rotating spindle, a fixed cooling shell, an additive forming tool head, an induction heating coil and other parts, wherein ultrahigh-strength solid-phase additive forming is achieved through the procedures of extrusion feeding, induction heating temperature rising, load applying and the like. According to the method, rapid heating and softening of the high-performance alloy steel are achieved through the induction heating principle, the severe large plastic deformation characteristic of stirring friction is combined, and the solid-phase additive manufacturing of the nearly-forged structure and performance of the high-performance alloy steel part is achieved. The device and the process can effectively break through the integral high-performance forming bottleneck of high-performance alloy steel complex components.

Problems solved by technology

However, the high-performance alloy steel has a high melting point and high deformation resistance. To realize the metallurgical bonding between the solid-phase layers in the additive manufacturing process, the additive forming temperature must reach above 1000°C. Only by the contact between the additive forming tool head and the material It is difficult to realize the frictional heat generation between
