有些研究者发现,用高的变形速度剪切时能提高毛坯的精度和改善剪切表面的质量。本文介绍高达70米/秒的变形速度对剪切毛坯质量影响的研究结果,这种毛坯是用不完全封闭剪切方法从棒料上剪下的。初始速度自8米/秒直至70米/秒的高速剪切试验,是在以火药为能源的冲击机上用试
Some researchers have found that shearing with a high rate of deformation increases the precision of the blank and improves the quality of the sheared surface. This paper presents the results of a study of the effect of deformation speeds of up to 70 m / s on the quality of cut blanks cut from bar stock with incompletely closed shear. Initial speed from 8 m / s up to 70 m / s high-speed shear test is to use gunpowder as a test machine impact energy
