摘　　要：在现有的管壳体挤压机中,管壳体卡痕质量不稳定,挤压活动板是管壳体挤压机中保证卡痕稳定性的重要构件,如果改变向上推力在挤压活动板上的作用点位置,可能获取不同的管壳体卡痕质量,笔者采用单工位多平均施力点的发散施力方式构建管壳体挤压塑变模型,并运用专业分析软件Inventor对挤压活动板进行内应力、位移、形变、管壳塑变等分析,建立了管壳体单工位多力点挤压塑变模型,对于改善传统管壳体挤压方式产生了较大的影响,同时极大的提高了管壳卡痕稳定性。Under existing squeezing machine of the tube,the quality of clasp mark of the tube is unstable,the movable squeezing plate is important components to ensure stability of clasp mark of the tube,if transforming the location of force of cylinder on the movable squeezing plate,different quality of clasp mark of the tube is got,using the diverse forcing way which is single workplace and multiple force point to structure the squeezing and plastic deformed model of the tube,and use the professional analysis software Inventor to carry out analysis of stress,displacement,deformation for the movable squeezing plate,and the squeezing and plastic deformed model of single workplace and multiple force point of tube is built,a big difference is made on improving the traditional squeezing way of tube,at the same time greatly improving stability of clasp mark of the tube.
