ABSTRACT:
A method for forming artistic forked pipes made of aluminum or copper alloy, including the steps of selecting of extruded material, milling for making an extruded pipe, enlarging the bore of a main pipe, and forming to form forked branch pipes. Wherein, an extruded material selected is provided with a plurality of through holes and protruding columns. The through holes are formed to have a main pipe on one end and a plurality of branch pipes on the other end thereof. The material of the protruding columns are milled to distribute on protruding portions on the main pipe, and on protruding portions on the branch pipes for making an extruded pipe. A die core with the corresponding shape of the main pipe has to be fitted in the main pipe hole of the extruded pipe to facilitate operation of exerting pressure onto the protruding portions of the main pipe to enlarge the bore of the main pipe into a desired form. A die core with the corresponding shape of the branch pipes has to be fitted in the branch pipe holes to facilitate operation of exerting pressure onto the protruding portions of the branch pipes to form forked branch pipes having the branch pipes flared. In this way, artistic forked pipes having large strength can be made, and forming technique of the forked artistic pipes of non-ferrous alloy can be improved.
