ABSTRACT OF THE DISCLOSURE The present invention relates to a method for pressworking articles and an apparatus to effect the same. Thus, there is provided a method for pressworking of articles, and more particularly by punching, extrusion, closed-die forging, briquetting, injection moulding or by other similar processes of articles, wherein the transmission of the amount of energy necessary for the pressworking is effected in several steps, each step comprising a high-power phase with release of previously accumulated potential energy in an elastically-deformable energy carrier and of a low-power phase of longer duration with release of energy from an auxiliary energy source of lower power, while the energies, the displacements of the tools and their velocities are conditioned by a previously programmed optimum law for the levels and their transitions between the different phases, at which law the production process runs according to the method with smoother transitions and is not disturbed because of the fact, that the rate of its run during the longer phase of lower power is regulated so that it is sufficient to avoid an abrupt increase of the coefficient of friction between the workpieces and the tools, while the velocities of the latter do not alter their sign till the completion of the working of the articles, and during the low-power phase of longer duration there takes place a recharging with potential energy of the elastically-deformable energy carriers, and then it is possible to effect the next-following step of pressworking on the same article.
