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

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.
