Investigation of deflections of winded screw flights and auger billets in the processes of their manufacture

Analytical dependencies to assess the rigidity of multi-profile screw flights during their manufacture by winding strip blanks with an edge on a mandrel were obtained, which made it possible determine profiles turns high and evaluate accuracy such blanks. The regularities deflection combined auger billet open closed windings in various ways its fixing process cold rib onto mandrels have been established.
