Stand equipment and theoretical study of strengthening the screw surfaces of extruders working bodies

Abstract

To increase the reliability of the screw working bodies operation, a lining tool is designed. Experimental equipment was developed and manufactured to determine their characteristics. The analytic dependences are developed. The graphic dependences of the projections of the impact force Pu in the contact point, the contact force Pk between the deforming punch and the screw working body, the friction forces F12 between the deforming punch and the screw working body from the angle a of the contact of the deforming punch with the screw working body are derived. Its application makes it possible to carry out researches with the possibility of modeling the corresponding processes in wide ranges with high accuracy in the automated control mode with fixation of necessary research results.
