Device for drawing-off and straightening cylindrically shaped stock

A device for drawing and straightening cylindrically shaped stock, mounted on a drawbench stand and comprising:

• a die case;
• a die fixed in said case;
• stock guides arranged along a drawing axis on both sides of said die;
• means for straightening the stock by applying alternating bending forces thereto;
• said stock straightening means, comprising:
• a housing, a drive rotor having an axis of rotation which coincides with the drawing axis, accommodated in said housing and incorporating said case with the die, bearings supporting said case and die eccentrically such that said die is non-rotatable about its axis;
• whereby when said rotor rotates during the drawing operation, said die transmits alternating bending forces to the stock, with said guides acting as supports when the stock being drawn is bent, a slider having an adjustable stroke adapted to reciprocate along an axis parallel to the drawing-off axis, one of said guides being disposed on the exit side of said drawing die and being fixed to said slider.
