There are some problems in the mid-pitch spinning prediction model that need to be discussed, but the characteristics of the mid-pitch value need to be discussed <br>. The existence of the parameters makes the relationship between the main parameters more complicated than the cylindrical rotation, resulting in such interference <br>offset spinning Characteristic phenomenon. <br>Taking the offset printing spinning prediction model as the research carrier, the key technical issues such as the establishment of the offset printing spinning forming prediction model and the influence of the process parameters on the rotor drying are studied, such as the establishment of the ls-dyna finite element simulation model that meets the actual working conditions. By improving the analysis of the offset spinning, the deformation mechanism and stress parameters of the offset spinning can be obtained. The mechanism of the offset method and the method of eliminating interference can be explored. There is no influence of the interference parameters, which provides a basis for the application of offset spinning. Good quality and high efficiency have laid the foundation in actual production.
