A section straightening machine is operated by a method which involves passing the structural sections through the array of straightening tools. Section straightening forces are applied to adjustable shafts carrying the tools and adjusters at the service sides of the shaft applying forces acting counter to the section straightening forces.

Method of operating a section straightening machine

In a straightening machine for straightening sections like rolled beams, wherein tools () are arranged on a plurality of mutually parallel driven straightening shafts () disposed above and below the alignment line in the transport direction of the product to be straightened, and of which preferably the upper straightening shafts () are adjustable for setting the straightening gap, the straightening shafts () are individually adjustable and each have on both sides an adjusting means engaging straightening shaft ends () whereby in straightening operations at least the adjusting means on the service side () remote from the drive side I is provided with a force (F) acting opposite to the straightening force (F) relevant hereto.

Section straightening machine

A method and a machine for straightening sections by eliminating multi-axle deviations from the required section and from the required straightness using one or more straightening tools arranged, in series above and below the material to be straightened, on straightening axles which are parallel with one another. The adjustment of the straightening force and the adjustment of the horizontal inclination of the adjustable straightening axle are carried out hydraulically. The hydraulic system is configured so that a rapid change in position is possible either at the front and rear hydraulic cylinders or exclusively at the rear hydraulic cylinder in such a way that the straightening force and/or the horizontal inclination of the adjustable straightening axle can also be set during the straightening process.
