Solid-phase molding processing method

A friction stir tool, comprising:

• a stirring head, a mounting portion, and a connection portion provided between the stirring head and the mounting portion;
• wherein the stirring head comprises a stirring main body and a heating ring provided on the stirring main body;
• the heating ring is sleeved on an end of the stirring main body away from a shoulder and a welding pin, and is separated from the stirring main body;
• the mounting portion is connected to an external friction stir welding machine, and is driven by the friction stir welding machine to drive the stirring head and the connection portion to rotate;
• the heating ring is heated by an inductive heating device;
• and
• the inductive heating device comprises a heating part spirally wound on an outside of the heating ring;
• a heat dissipation groove is provided on an outer peripheral wall of the connection portion;
• wherein the heat dissipation groove comprises vertical grooves provided along an axial direction of the connection portion, and at least two vertical grooves are provided around the connection portion at intervals in a circumferential direction;
• wherein a sleeve is sleeved on an outside of the friction stir tool, and a cavity corresponding to the heat dissipation groove is provided inside the sleeve, to collect cooling liquid thrown out of the heat dissipation groove into the cavity;
• wherein the sleeve comprises a first sleeve and a second sleeve which are detachably connected;
• a concave-convex structure fit is adopted at a joint of the first sleeve and the second sleeve;
• a bearing sleeve is provided inside the first sleeve;
• and
• a bearing rotatably connected to the mounting portion is installed inside the bearing sleeve, so that the friction stir tool rotate relative to the sleeve.
