The number of the inner through holes 7 is at least 3, and the inner through holes are uniformly distributed along the arc length direction.
The number of the arc-shaped notches 3 depends on the material quality of the modified material, the modified area and the service life of the stirring head, but is at least 4.
When the stirring head clamping handle 1 is installed on the friction stir welding main shaft, the stirring head clamping handle 1 drives the shaft shoulder 2 to rotate, the arc stirring blades 4 installed on the arc notch 3 on the shaft shoulder 2 rotate together, heating resistance wires 8 in the arc stirring blades 4 start to heat, the arc stirring blades 4 contact with the surface of modified metal to cut and friction plasticize the metal on the surface of the modified metal, meanwhile, the metal on the surface of the modified metal is plasticized more rapidly through heating of the heating resistance wires 8, plastic flow is carried out between the inner arc notch 5, the outer arc notch 6 and the inner through hole 7 of the arc stirring blades 4, so that plasticized metal is uniformly paved on the surface of the modified metal, and a metal surface modified layer is formed through the action of the downward pressure of the shaft shoulder.
The invention has the beneficial effects that:
The stirring head designed by the invention is designed and manufactured based on the principle of combining heating by the heating wire and stirring, has simple structure, convenient operation and low price, and is easy to popularize and apply.
The essence of the invention is that the stirring blade with resistance wire heating and the stirring blade structure with special design lead the metal of the modified metal surface layer to plasticize faster and the surface layer to be paved uniformly.
