When stirring-head grip shank 1 is mounted on agitating friction weldering main shaft, the shaft shoulder body that is connected in stirring-head grip shank 1
2 rotate with main shaft, and the stirring cutter hub 3 on shaft shoulder body 2 is driven to rotate, and the rotation of stirring cutter hub 3 drives horizontal type knife 6 and perpendicular type knife
7 in modified metal surface friction and cutting metal, is gradually rapidly heated and is plasticized the metal of modification area, plasticized metal is in guide channel
It is squeezed at 4 in light cove 5, modified surface layer is uniformly routed to by the rotation of light cove 5, it is modified to form uniform surface
Layer.
Essence of the invention be exactly pass through to be stirred for a shaft shoulder bottom equipped with laterally and two kinds of vertical blades, and by pair
Shaft shoulder bottom is provided with guiding groove and circular groove, is quickly plasticized shaft shoulder bottom metal by two kinds of blade cut stirrings, then exists
Plasticized metal is introduced into circular groove under the action of guiding groove, gets rid of to form uniform surface by the quick throwing of circular groove
Modified layer.This stirring header structure design is simple, easy to use, application easy to spread.
Beneficial effects of the present invention:
Stirring header structure designed by the present invention is simple, and cost is low, and modified metal surface performance is good, high-efficient, price
Cheaply, application easy to spread.
