Research Progress in Tube Punching Technology

Explored systematically are relevant theories and applications and the newly-made progresses with respect to the three primary processes of tube punching technology,i.e.,tube cutting,tube-end trimming by punching and tube hole punching.The main problems as encountered with tube punching operation are analyzed. Also discussed is how to use the numerical simulation method for processing tubular products with punching technology in a bid to further improve the formation quality of tube-punching process.
