Manufacturing method of heat transfer plate

摘要

Problem to be solved: to reduce the occurrence of burr and to appropriately connect the friction tool to suppress the frictional heat generated when the rotary tool is inserted or detached.After the rotating tip pin F3 is inserted into the start position set at the surface 2a of the base member 2,The tip pin F3 is gradually pushed to a predetermined depth while moving the rotation center shaft of the rotary tool f to a position overlapping with the butt part, and theRelative rotation of rotation tool f along the buttThe outer peripheral surface of the base end pin F2, the surface 2a of the base member 2 and the surface 5a of the cover plate 5 are brought into contact with each other.The plastic flow material produced by friction stir is injected into the gap by the outer peripheral surface of the base end pin F2.Selection diagram
