Patent ID: 10946448

Abstract:
The present invention discloses a cold additive and hot forging combined forming method of amorphous alloy parts. The present invention belongs to the field of cold additive manufacturing technology and thermoplastic forming of amorphous alloy, and more particularly relates to a cold additive and hot forging combined forming method of amorphous alloy parts, the method comprising: (1) making amorphous alloy powder into a pre-forging blank by the micro-jetting and bonding 3D printing technology; and (2) placing the pre-forging blank in the step (1) in a closed forging die to perform hot closed-die forging so as to obtain an amorphous alloy part, wherein the contour size and shape of the pre-forging blank are designed according to the contour size and shape of the inner cavity of the closed forging die; and an exhaust hole is provided in the closed forging die such that gas generated by gasification or decomposition of the binder at a hot die forging temperature is discharged through the exhaust hole in the closed forging die. In the present invention, a bulk amorphous alloy part with a large size and a complex shape can be prepared by the cold additive and hot forging combined forming method.
