Abstract：
|
|
An expression about the rational shearing speed of high-speed shearing was put forward.This is an important influencing parameter on the section-quality of shearing process and is useful for the widely promoting this technology.The conclusion was drawn considering the related theory of fracture mechanics and plastic mechanics on crack technique.The analysis and correlation about the influence of different speed on shearing section′s microscopic structure by metallurgical phase test were presented.It was further demonstrated that high-speed shearing could get a better section quality than common shearing.
