Study of the dynamics of calibrating the turn of conical screw billet on a step

Abstract

The technological process of forming the conical screw billets, which are widely used in agricultural machinery engineering, is investigated. The analytical dependences for deter-mining the power and structural parameters are derived. The graphical dependencies of changing different types of deformations during the formation of screw blanks on a step are developed.The results of studies on the change in the angle of deformation of the spindle of the installation and the mandrel for time calibration, the linear deformation of the mandrel for calibrating in the y-direction in time, the linear deformation of the wedge in the z-direction in time, and the linear deformation of the wedge in the y-direction in time during the calibration process turn a conical screw billet in one step.
