WH A WH type skeleton bulge tool fatigue test device

摘要

The present invention relates to a WH type skeleton bulge tool fatigue testing apparatus, and more particularly, by repeatedly applying a load to the boundary between the bulge and the slot of the bulge tool to measure the fatigue degree of the bulge tool, thereby improving the bulge tool production quality. The present invention relates to a WH-type skeletal bulge tool fatigue test apparatus that enables the development of technology for the test and also the quality of the bulge tool prototype. To this end, both sides of the fixing bracket is formed through the tool hole; A tool housing coupled to the tool hole of the fixing bracket and having a bulging tool inserted and installed to expose the bulge of the bulging tool through one side thereof; A moving rail installed at one side of the fixed bracket in the longitudinal 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 a reciprocating movement of the moving bracket; Measurement means installed between the pusher and the moving bracket and measuring a load applied to the bulge tool while the pusher moves in and out of the bulge tool; A driving means for generating power for reciprocating the moving bracket on the moving rail, wherein the plug is fastened so that the bulging tool inserted in the tool housing does not escape from the tool housing, and the plug and the tool housing Is interposed between the washer is configured to vary the gap between the plug and the tool housing, the plug is screwed to the front end of the tool housing, both sides of the plug is formed through, the washer is provided in one or more The interval between the plug and the tool housing is variable, to provide a WH-type skeleton bulge tool fatigue test device, characterized in that configured to be able to vary the bulge exposure length of the bulge tool exposed through the plug.
