Definitions

document EP-A-0577170 describes an installation in which the whole of the leveling equipment constituted by the active cylinder and the associated support rollers is mounted on a chassis in the form of a beam extending between the two uprights of the cage and bearing on the crosspiece, on the one hand on stops, at the uprights and, on the other hand, between the uprights by means of flat cylinders which make it possible to adjust the distribution of the forces d support on the length of the crosspiece to compensate for the deformations thereof.
each support member 3 comprises a rotary support part mounted in an individual chassis forming a housing, connected to the cross-member with a possibility of play transversely to the running plane and each of said cases bears individually on the cross-member by means of a variable length positioning member, for the individual adjustment of the level of the corresponding support part with respect to the cross-member.
the positioning member associated with each support member is an actuator of the jack type, hydraulic, pneumatic or mechanical, comprising a first element fixed to the cross member and a second element mounted to slide perpendicular to the mean plane of travel and having a face in contact with the housing of the support member, said actuator being associated with means for adjusting the relative position of the second element with respect to the first.
each support member can be connected to the crossmember by at least two suspension rods with the possibility of play with respect to the crossmember, each rod being provided with an elastic stop for returning the housing to the cross member, sliding along said rods.
the entire leveling crew is carried by a chassis 4 which is supported on a beam-shaped cross member 5 the ends of which are threaded into the recesses 10 of the two uprights 11 and 12 and which is supported on two jacks 13a, 13b fixed on said uprights 11, 12 and which collect the vertical lifting forces applied by the strip A on the cylinder 2 during leveling.
the lower bending unit D2 comprises a lower leveling unit consisting of an active cylinder 2 'bearing, by means of rollers 21' and rollers 3 ', on a transverse frame 4' which, in the example shown, itself rests on a box spring 5 'via 2 mechanical jacks 13'a, 13'b for adjusting the level of the chassis 4' and the associated leveling crew.
the jacks 13'a, 13'b are mechanical screw jacks, driven in synchronism by a motor 14.
the strip is subjected under tension to two alternating flexions on the active cylinders 2, 2 ′ offset in height, which tend to move apart while resting on the cage, each by means of the support members. 3, 3 ', the chassis 4, 4', the cross member 5, 5 'and the cylinders 13, 13'.
each box 32 is associated with a positioning cylinder 6 comprising two elements, respectively a fixed body 61 and one on rails 55 formed on either side of the cross 5 movable piston 62 whose position relative to the body 61 is determined by an actuator 63.
the screw jacks 6 corresponding respectively to the various support members 3 are advantageously arranged inside the cross-member 5 on which the upper leveling equipment D1 is supported and which consists of a resistant beam in the form of a hollow box with rectangular section, limited by a lower face 51, an upper face 52 , two lateral faces 53 and two end faces 54 the bodies 61 of the jacks 6 being fixed on the underside 51 of the beam.
the plate 4 for supporting the active cylinder 2 and its intermediate rollers 21 extends below the lower face 51 of the cross-member 5, over the entire length of the latter. As indicated above, this plate 4 is applied, in service, against the underside 51 of the beam 5 which thus collects the vertical forces exerted by the strip A on the active cylinder 2 during leveling and is supported on the two uprights of the cage 1 by means of the jacks 13a, 13b.
the adjustment jacks 6 which can each be associated with an encoder, the control of the deformation of the leveling cylinder and / or of the forces applied can be ensured, either manually by the operator, from the observed or measured results, either automatically, for example with a preset system from an experimental model or else with a closed loop system associated with a flatness measurement and control device of known type.
the leveling device can also be used in a conventional manner for products which do not require correction.
the jacks 6 keep the pistons 62 back, all the housings 32 of the support members are brought back to the level of the support plate 4 itself applied against the underside 51 of the beam 5 and the assembly can be used as a normal bending unit.
the support plate 4 could be integral with the cross-member 5, the assembly constituting a cassette mounted horizontally sliding inside the cage and thus being able to be removed as a whole from the cage then replaced inside of it.
the support plate 4 is suspended by rollers 45 from the cross-member 5 and constitutes, with the leveling equipment comprising the active cylinder 2 and its support members, a particularly cassette light which can be lifted by the jacks 13 in the position of Figure 5 for which the rollers 45 rest on two rails 55 formed on either side of the cross 5.
the plate 4 can then be removed from the cage 1, by axial sliding, for maintenance or replacement of the active cylinder 2 and / or the support members, by rolling on the rails 55, up to the withdrawal position shown in FIG. 2A.
the cross-member 5 remains in place inside the cage, with the adjustment jacks 6.
the drive means are generally arranged on the same side of the cage, the operator being placed on the other side as well as the various maintenance members.
the crossmember 5 remains in place, only the plate 4 being removed with the leveling crew. This lightening of the movable and rotating cassette facilitates maneuvers.
the cross-member 5 is advantageously suspended from a transverse plate 14 extending between the two uprights 11 and 12 of the cage and fixed on the ends of the rods of the two adjustment jacks 13a, 13b.
the plate 14 is provided with two rails 15 on which rollers 56 can rotate mounted rotatably above the level of the rails 15.
the cross member 5 can thus be suspended from the transverse plate 14 by two pairs of rollers 56 carried by arms 57 fixed, respectively, at its two ends.
the assembly After removal for maintenance and replacement of the cassette 4 and, optionally of the cross-member 5, the assembly is applied to the stops 16 of the cage and maintained by the side plates 58 in a service position fixed by the locking devices. 74 and 18 and for which the crosspiece 5 and the plate 4 are integral with the cage 1 so as to resist the vertical forces applied by the strip on the active cylinder 2 during planing.
the upper unit D1 associated, according to the invention, with members 6 for positioning the support means 31.
the lower bending unit D2 is produced in a conventional manner, the support members 3 'of the lower active cylinder 2' being directly fixed to a chassis 4 ' in the form of a relatively rigid beam which rests on the bed 5 'by means of mechanical jacks 13'a, 13'b.
these are detachably connected with the support frame 4 'which, with the lower assembly 2', 3 ', forms an interchangeable cassette capable of being withdrawn from the cage by rolling on lower rails 51 '.
the support frame then consisting of a simple plate applied directly to the fixed cross-member 5 ', the support members 3 'being mounted in boxes whose position could be individually adjusted as indicated above.
the leveling cylinder is supported, in a conventional manner, on intermediate rollers and support rollers.
the arrangements according to the invention could however apply to other support means with the possibility of rotation of the cylinder such as, for example, plain bearings.
