Device and method for adjusting or setting a rolling gap of a two-roll straightening machine for rods and/or profiles

A two-roll straightening machine for rods or profiles, in particular a skew rolling straightening machine, comprising:

• a roll frame;
• two adjustable straightening rolls;
• a measuring device for providing an assessment value arising from an assessment of a rod or a profile;
• and
• an open-loop or closed-loop control for an adjustment or setting of the straightening rolls,
• wherein each straightening roll is connected to a fully hydraulic drive for changing the adjustment or setting of the straightening rolls relative to each other;
• and
• wherein straightening forces generated by straightening the rod or the profile are substantially transmitted to the roll frame by the fully hydraulic drive.

A method for adjusting or setting a rolling gap of a two-roll straightening machine for rods or profiles, in particular a skew rolling straightening machine, having

• a roll frame,
• two adjustable straightening rolls,
• a measuring device for providing an assessment value arising from an assessment of a rod or a profile, and
• an open-loop or closed-loop control system for an adjustment or setting of the straightening rolls relative to each other,
• the method comprising:
• adjusting or setting the straightening rolls through two fully hydraulic drives, one of the two fully hydraulic drives being assigned to each respective straightening roll;
• and
• substantially transmitting straightening forces generated while straightening the rod or the profile to the roll frame by the fully hydraulic drives.
