中文摘要: |
为减小压力分布不均匀对胶管质量造成的影响,对胶管外胶层挤出机头进行优化设计。通过在挤出机头后盖上增加内衬,避免压力分布最不均匀的一段直接作用在胶管上;在机头内设置环形储料腔,使胶料从各个方向均匀地挤入口模,达到消除压力对外胶层厚度的影响的目的;运用ANSYS/Polyflow软件对所设计的机头进行有限元分析,检测了其可行性。 |
英文摘要: |
In order to reduce the influence of uneven pressure distribution on the rubber hose quality,the design of extrusion die for the outer layer of rubber hose was optimized.Lining was added on the back cover of the extrusion die head which reduced the effect of the most uneven part of pressure distribution on the extruded rubber hose.In addition,a ring shape rubber storage tank was equipped at the extrusion die,which allowed the all direction extrusions of rubber into the die and eliminated the influence of pressure on the outer layer thickness.The optimized die was analyzed by using the ANSYS/Polyflow software and the reliability was tested. |
