“…If the technology includes dragging, total losses of the metal are about 33% of the metal output. The metal wastes by removing the hooks are about 20-40% of the total wastes or about 13.5% pre 1 tonne of the finished tubes [7,8]. Thus, the problem of the production of qualitative pipe hooks and the minimization of the material wastes is relevant and requires the effective equipment development for its decision.…”

This paper gives an account of a new project for the design and production of a radial cyclic forging machine. This new design considers the advantages of its predecessor and of modern trends within the engineering industry. The use of this machine could enable the considerable reduction of production wastes. Besides the cold cyclic technology implemented in this machine, it will also allow for the increase in energy efficiency, for the minimum capital investments.

“…In modeling of preparatory operation round, figure-of-eight and trefoil-type shapes of the forged pipe end cross-section were considered [6]. The forging was achieved by one stage without a preliminary heating of corrosion-resistant pipe billet.…”
