The invention discloses a forming gluing method for an amorphous alloy three-dimensional wound core. The gluing method is implemented through a wound core forming gluing device and superficially includes the steps that firstly, a wound core is placed on the wound core forming gluing device, and annealing forming is carried out; secondly, four hydraulic jacks are started after annealing forming to make the jacking height larger than the thickness of backing plates; thirdly, the other three backing plates except the backing plate closely attached to the lapping head of the wound core are drawn out; fourthly, the three backing plates which are drawn out are coated with a release agent and epoxy resin in sequence and then put back on bottom plates, and the backing plates are seamlessly attached to the bottom plates; fifthly, the lower surface of the wound core is coated with epoxy resin; sixthly, the upper surface of the wound core is coated with epoxy resin, and after the epoxy resin is cured, gluing of the wound core is completed. The process of carrying out mould entering first and then carrying out annealing is adopted in the method, it is not needed to overturn the wound core in the gluing process, and the performance of the wound core is guaranteed.
