| 摘 要： | 基于DEFORM3D模拟软件,针对连续挤压包覆过程中模腔流动通道长度和挤压轮转速对铝护套产品的影响进行有限元模拟分析,并进行实验验证。结果表明,模腔中流动通道长度对改善金属流动的均匀性、产品的弯曲角度和横截面的椭圆度发挥重要的作用,增加流动通道长度,可以使产品的流动速度变得均匀,产品的弯曲角度接近理想的零值,并可以获得良好的截面形状;当使用较长的流动通道时,挤压轮转速对产品的弯曲角影响不大。

| Abstract: | The effect of flow passage length in the die cavity and extrusion wheel velocity on the shape of aluminum sheath during the continuous extrusion sheathing process was analyzed by using finite element methods based on software DEFORM 3D and experimentally validated. The results show that by increasing the flow passage length, the velocity of metal at the cross-section of sheath tends toward uniformity, the values of the bending angles of sheath gradually approach the ideal value of zero and the cross-section exhibits a better shape. The extrusion wheel velocity has negligible effects on the bending shape and cross-section of the sheath product when a long flow passage is used. |
