Document Type and Number:
WIPO Patent Application WO/2013/187734
Kind Code:
A1
Abstract:
Disclosed is an apparatus for manufacturing a contact tip for a welding torch by forging. The apparatus for manufacturing a contact tip for a welding torch by forging according to the present invention comprises: a connection unit molding assembly for pressing a base so as to form a first form having a first connection unit hole; a body hole molding assembly for pressing the center of the first form so as to form a second form having a second body hole; a communicating molding assembly for pressing the center of the second form so as to form a third form in which the first connection unit hole and the second body hole are placed in communication; and a head unit molding assembly for placing a finishing pin, the diameter of which is larger than the diameter of a welding wire, in the third form, and pressing the third form so as to form a fourth form having a fourth head unit hole. According to the present invention, the base having a circular cross-section can be used, and rapid variations in the diameter and shape of the base can be prevented during the formation of the connection unit and the connection unit hole. Therefore, loads being applied to each formed protrusion can be significantly relieved to thus reduce the risk of damage to the formed protrusions and improve productivity.
