Theoretical force calculation at swaging in a profiled die block.
Engineering Education # 09, September 2011 The article deals with calculation of the swaging force of axisymmetric tubing stocks with use of a die block the body of which has ring grooves. Positions formulated by E.A. Popov are used as basic theoretical preconditions of the analysis. The article shows a scheme of internal and external forces during swaging as well as piece-part shaping stages. When using the die block with ring grooves the edge of the swaged tubing stock makes movements into the a groove during the shaping process, and then it moves out, being out of contact with the die block surface. Such way of swaging by means of flutes allows to reduce swaging force and to increase the degree of forming at the expense of reducing the contact friction force, thus reducing the number of process steps at stamping.
