FIELD: metal forming by pressure.
SUBSTANCE: invention relates to the field of pressure treatment, in particular to the device for straightening polished rods or rods of the downhole pump, which is installed on the wellhead. On foundation, made in form of reinforced stiffness ribs of trapezoidal frame, fixed stops are installed to hold polished rod or rod, a power mechanism made in the form of a screw-nut pair, a movable stop rotatably connected to the end face of the said screw of the power mechanism, which is made with possibility of longitudinal movement with rotation in the nut perpendicular to the base of the bedplate. At that, movable stop is connected with screw by threaded connection.
EFFECT: increased reliability of the device and possibility of its use on workbenches and tables due to execution of bed with stiffness ribs.
