The determination of the deformation parameters for high-speed extraction of axisymmetric thin-film blanks that ensure the shaping of parts without distortion of the shape of the relief and destruction of metal by the method of pneumatic impact punching is performed. On the basis of the conducted researches the technological possibilities of manufacturing of quality axisymmetric thin-walled details by the method of pneumatic impact punching are established. The conditions for the stability of the workpiece when forming the axisymmetric elements of a non-spherical shape are similar to the conditions for the stability of the workpiece during the shaping of spherical elements, and the results can be extended to the drawing of elliptical, shallow conical and other similar parts. Pneumatic impact punching allows you to pull dome-shaped parts without the use of hanging thresholds, two-transversal stamping and other special techniques with a relative billet thickness of two to four times less than allowed when drawing a punch.
