Finite element simulation on plastic forming process of multi-interface tube material in lightweight food equipment

研究轻量型食品装备多界面管材的塑性成形工艺。以食品机械轴头的多界面管材为研究对象,确定了塑性成型的方法,通过DEFORM软件研究了温度和摩擦系数对管坯壁厚增量、端部内径以及载荷的影响,并对产生的常见缺陷提出优化方案。研究表明,该工艺将冷挤压与温挤压的优点相结合,节材减重,可满足小型食品机械零部件生产的需求。

This paper studied the plastic forming process of multi-interface tube materials in lightweight food equipment.Taking the multi-interface pipe of the food machinery spindle head as the research object,the plastic forming method was determined.The effects of temperature and friction coefficient on the tube wall thickness increment,the end inner diameter and the load were studied by DEFORM software,and a plan was designed to optimize the common problem.Studies have shown that this process combines the advantages of cold extrusion and warm extrusion,saving materials and losing the weight,and can meet the needs of small food machinery parts production.
