Failure and Failure Mechanisms Analysis of High-Speed Punch

Abstract

According to the main characteristics and functions of a high-speed punch, the system was divided into nine function subsystems systematically. Based on failure data, the failure positions, failure mode, failure causes and failure cause classification were detailed statistical analyzed. And the weakest links and potential shortcomings of the high-speed punch were pointed out. Some failure mechanisms of the high-speed punch, such as oil/gas leakage, crankshaft failure and so on, were analyzed especially. The improvement measures, which lay the foundation for the reliability growing of the high-speed punch, were drawn based on the failure and failure mechanisms analysis.
