Definitions

a method of this type has become known from US-A-4,730,472 and makes it possible to preset the support rollers of straightening machines in such a way that, taking into account the deflection of the crossbeams under the straightening force, the straightening roll deflection is compensated and the straightening rolls are therefore straight when straightening.
the actuating cylinders acting on the crossbeam for this purpose are position-controlled, i.e. the forces occurring at the individual support points are completely ignored. It is only ensured that the cylinders ultimately return to their preset position or position even when load peaks occur.
EP-A-0 182 062 which there act on the straightening rollers indirectly above the complementary rollers serving as supports.
the invention has for its object to provide a method of the type mentioned with which the operation of the straightening machine can be improved, in particular the straightening gap can be maintained even more precisely.
This object is achieved in that the sheet width and sheet position with respect to the machine center and the inlet and outlet side left and right of the machine center total forces acting on each adjusting cylinder are measured, from which and taking into account the crossbeam deflection, a calculator the percentage of Individual forces are calculated, and the individual forces that change depending on the load are then calculated according to the measured cylinder forces and the calculated percentage distribution are regulated.
a variable regulation of the straightening gap under load is thus achieved as a function of the forces actually occurring during straightening, these forces, which counteract the forces widening the straightening gap, being set in accordance with the calculated percentages; a constant straightening gap can be maintained in this way.
the force of each of the four positioning cylinders which can be different for an eccentric sheet run and therefore an eccentric straightening force for each positioning cylinder, are known, the equilibrium of forces and the corresponding deformation equations as well as the condition that the roller mills have no deflection at outer support points and only the deflection of the crossbeams is compensated for, the individual forces required between the support points to compensate for the crossbeam deflection.
the outermost individual forces acting symmetrically to the center of the machine are preferably set automatically due to the regulated straightening gap and only the internal individual forces are regulated. These external individual forces correspond to fixed stops.
a control deviation of the regulated individual forces is absorbed.
the differential force from the straightening force and the weight force must not exceed the balancing force.
Adjusting wedges 8 are mounted on the lower roller mill 7, each of which can be displaced by a pressure medium cylinder 9.
a bearing bracket 11 for lower straightening rollers 12 and supporting rollers 13 associated therewith is supported on each wedge; webs 14 are arranged between the support rollers 13.
several upper straightening rollers 15 are arranged by support rollers arranged between webs 16 17 supported on their bales.
the upper straightening and support rollers 15, 17 are mounted on a bearing bracket 18.
Each of the adjacent bearing supports 18 is supported on a wedge 21, the other side of which rests on the upper roller mill 6.
the adjusting wedges 21 can be displaced by one pressure medium cylinder 22 each.
the upper and lower straightening rollers 15, 12 are individually driven and connected to a drive (not shown) via cardan shafts 23.
