1. An apparatus for fatigue testing a bulge tool having a WH-type skeleton, the apparatus comprising:
a fixing bracket having tool holes penetrated through opposite sides thereof;
a tool housing coupled to the tool hole of the fixing bracket and having the bulge tool inserted and installed therein so as to expose a bulge portion of the bulge tool through one side thereof;
a moving rail installed at one side of the fixing bracket in a lengthwise direction of the tool housing and providing a reciprocating movement path toward the tool housing;
a moving bracket reciprocating along the moving rail;
a pusher protrudingly installed from the moving bracket toward the tool housing and, moving in and out of the bulge tool by the reciprocating movement of the moving bracket;
a measurement means installed between the pusher and the moving bracket, for measuring a load applied to the bulge tool while the pusher moves in and out of the bulge tool; and
a drive means for generating power for reciprocating the moving bracket on the moving rail.
