模具锥角对冷拔内螺纹管成型及力能参数的影响
EFFECTS OF DIE TAPERS ON FORMING AND STRESS PARAMETERS OF INSIDE-THREADED PIPE COLD DRAWING
-
摘要: 介绍了内螺纹管拔制特点,讨论了内外模锥角对拔制过程的影响。通过实验和分析,得出了力能参数较低而成型较好的模具锥角。Abstract: Thea characteristics of inslde-threaded pipe drawing are described and the effects of tapers of male and female dies on pipe drawing are discussed. Reasonable die tapers, which can reduce the values of stress parameters and improve forming, are obtained based on experiments and analysis.
