Title:
APPARATUS FOR FATIGUE TESTING BULGE TOOL HAVING WH-TYPE SKELETON
Document Type and Number:
WIPO Patent Application WO/2019/216476
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for fatigue testing a bulge tool having a WH-type skeleton and, more particularly, to an apparatus for fatigue testing a bulge tool having a WH-type skeleton and which is capable of: repeatedly applying a load to a boundary between a bulge and a slot of the bulge tool to measure a fatigue degree of the bulge tool, thereby both promoting the development of technology for improving the quality of bulge tool production and testing the quality of a bulge tool prototype. To this end, provided is an apparatus for fatigue testing a bulge tool having a WH-type skeleton, comprising: a fixing bracket having a tool hole penetrated through both sides thereof; a tool housing coupled to the tool hole of the fixing bracket and having a bulge tool inserted and installed so as to expose the bulge of the bulge tool through one side thereof; a moving rail installed at one side of the fixing bracket in the 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 protruding 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.
