Abstract

During the expanding of tubes in a tube wall, by a roller-type rolling tool, the variable effort applied to the tool is measured simultaneously with a linear variable of the expanding operation over three successive stages or areas affected by the expansion, viz, the area of elastic deformation of the tube work, the area of plastic deformation of the tube up to the moment of the engagement of the external surface of the tube with the surface of the opening of the tube wall, and the area of elastic deformation of the tube wall, and the control over the expanding operation is optimised by processing the measured data, in accordance with the geometric dimensions and the mechanical properties of the materials of the tube and of the tube wall.
