再论型材位置对挤压模工作带长度的影响
首发时间:2004-10-06
摘要:现有工作带设计公式中考虑了截面大小和周长长短的影响,但没有考虑位置的影响。尽管有若干办法可以修正,还是缺乏通用性。采用逆向模拟方法,研究了材料流动与位置的关系,量化了位置与工作带的关系。

Effect of Shape Position on the Length of Die BearingⅡ
Abstract:Only the size and circumference of shape are taken into account in designing the extrusion die bearing now,. position effect on the die bearing is not clearly clarified, though there are some approximate methods. The relation between the velocity of flow and the position of shape is studied by means of adverse simulation test and reasoning. The relationship between the position and the length of die bearing is given quantitatively.
Keywords: shape extrusion, die bearing, position, flow velocity, simulation
