空拔管直径缩小量的研究

INVESTIGATION ON DIA. SINKING IN SINKING DRAWING

摘要: 研究了不同变形量、钢种、硬化程度、模角和拔制速度对空拔管直径缩小量的影响。实验表明,直径缩小量随减径量和模角的增大而增大;非连拔道次比连拔道次对直径缩小量的影响大;低速拔制时直径缩小量的影响较小。

Abstract: The effects of various amounts of deformation, steel grades, degrees of hardenability, die entry angle and drawing speeds on dia. sinking drawing are studied. The experiment shows that the magnitude of dia. sinking is increased with the increase of reduction and die entry angle; the influence of discontinuous drawing passes on dia. sinking is greater than that of continuous ones; low-speed drawing has less influence on dia, sinking.
