等壁厚扁平截面型材的导流模横向尺寸设计
首发时间:2005-01-04
摘要:导流模可以调整挤压时材料的流速,如何设计导流模的横向尺寸,至今没有一个完整客观的公式或方法。在前期的挤压模工作带长度确定的研究基础上,对等壁厚扁平截面型材的导流模横向尺寸设计方法进行了研究,得出了比较简洁客观的计算公式。

Determining Lateral Size of Flow-guide Die
Abstract:It is well known that flow-guide die can control the material flow velocity in section extrusion, however the design of the flow-guide die is in the state of trial and error or qualitative description based on ones experience. Based on the previous study on bearing land of extrusion, a formula is proposed, which shows the relationship between sections, bearing land, flow-guide die and extrusion container. The formula is compared with the publishd one, and qualitative agreement is achieved.
Keywords: flow-guide die lateral size, extrusion die, flow velocity distribusion
