A device mounted on a drawbench stand, comprising a case with at least one drawing die or draw head, and stock guides arranged along the drawing-off axis on both sides of the die. Mounted intermediate of the stock guides is a stock straightening gear, including a housing accommodating at least one drive rotor whose axis coincides with the drawing-off axis. The rotor carries the case with the die set up eccentrically in bearings and non-rotatably about its axis. As the rotor rotates during the drawing-off operation, the drawing die transmits alternating bending forces to the stock, the guides acting as supports while the stock is bent.

A method of producing cylindrical tubular items by drawing and a draw bench relate to methods and devices for plastic working of materials in a cold state. In the course of manufacturing cylindrical tubular items by drawing, said items are subjected to deformation on being drawn through a die and are imparted simultaneously a torsional moment, said torsional moment being imparted to that portion of each item which emerges from the die, while the item portion found in front of the die is restricted from torsion. The draw bench adapted for realizing the method of the invention comprises a device for drawing items through the die, said device being made as a driven carriage, a means for imparting to the item a torsional moment, said means being arranged on said carriage, and a means for restricting the item from torsion arranged at the die entry. Such method and draw bench allow obtaining drawn items featuring sufficient rectilinearity to be transferred to subsequent technological operations without intermediate and final straightening thereof.
