Definitions

  • the invention relates to the field of flattening strips of material such as strips or metal plates. It relates in particular to a planing unit according to the preamble of claim 1 adapted to plan a spectrum as wide as possible band thickness.
  • planing unit for thick strips requires the use of planing rollers with large diameters and vice versa that a planing crew for thin strips (for example less than 5mm) requires the use of planing rollers of smaller diameters.
  • planing rollers being arranged in a set of upper and lower cassettes (also called “assembly cassette assembly") thus forming a leveling unit capable of being disposed in a leveling installation provided with a structure sized to receive at least the said cassettes.
  • Planing operations on different strips require frames of various sizes because of the cassettes and their rolls of different sizes.
  • the drive elements of the rollers have different characteristics depending on the choice of cassettes, rollers or racks due to settings conditioned by the thickness, the type of tape, but also the speeds and pressures required of the rollers. training or support.
  • a leveling frame can receive interchangeable cassettes comprising rolls of different sizes (diameter, length) and whose axes are juxtaposed in appropriate steps, it is necessary to interchange a cassette with another cassette, also interchange some of the drive elements of the rollers. These maneuvers are complex, expensive and require long shutdown planing facilities.
  • planing off of strips or plates is obtained by a succession of alternating flexions of decreasing amplitude without application of external traction upstream or downstream of the leveling machine.
  • leveling machines comprise two planing equipments each carrying a series of rollers with parallel axes placed respectively above and below the strip, the rollers being offset longitudinally and vertically, so as to interlocking by determining a wavy path of the band which is thus subjected to successive alternating bending effects.
  • These alternating flexures result in curvatures generating in the band, deformations which vary from a state of traction to the extrados of the curvature to a state of compression at the intrados, passing through a zero value in the axis.
  • the thickness fraction of the plasticized strip is usually expressed as a percentage of the total thickness referred to as the "plasticization ratio”.
  • the control of the planing operation depends on the control of the curvatures generated with each alternating flexion, control that faces two difficulties.
  • each leveling unit respectively lower or upper, comprises a plurality of rollers with parallel axes which normally have a reduced diameter and are therefore supported by at least two supporting rollers which can themselves bear on rows of rollers, all of these rollers and rollers being assembled on a frame.
  • the lower leveling crew is supported on the fixed bed base and, bearing the opposite side upper crew optionally integral with a movable beam that can be moved vertically between the four columns by means of mechanical or hydraulic cylinders supported on the part upper frame, so as to adjust the spacing of the two planing crews and, therefore, the nesting of the rollers, taking up the spacing forces due to the strength of the product.
  • planing rollers are rotated about their axes in order to advance the strip or plate by friction, at a predetermined speed, following a corrugated path between the lower and upper rollers.
  • EP 1 584 384 proposes to have several types of upper and lower planing equipments carrying a different number of rolls of diameters also different and, including gear distribution systems in order to move from one number of rollers to another with the same engine. These distribution systems provide that each roll of the various crews is rotated by means of a connectable distribution extension tree, said extension shaft being at one of its ends removable from the roll and at the other end thereof connected to a box additional distribution, itself directly driven by the engine.
  • the present invention proposes to solve the problems of the prior art by proposing a leveling installation which provides mainly a planing for a very wide range of thickness of strips to planer. For example, this interval should cover thicknesses of a few millimeters up to several centimeters. For this purpose, knowing that this spectrum of tape thickness imposes equipment comprising roll configurations of different diameters, the present invention also proposes to ensure interchangeability of coupling of these different rollers with unique and fixed means of motor training so as not to need to complement (and therefore oversize) or even interchange these means.
  • the present invention also aims to minimize the number of transmission shafts, said elongated, and to avoid having to change the configuration of said extensions, regardless of the roll diameters and the number of rolls of the various crews removable, interchangeable and useful for flattening strips with large differences in thickness, such as a gap of several centimeters.
  • the torque distribution module is thus arranged and coupled between the second rolls of the second cassette assembly and the extensions, the latter extensions being thus formally the same as those of the first rolls of the first cassette assembly.
  • This aspect thus allows whatever the number or the chosen diameters of the rolls of the second cassette frame.
  • the extensions therefore retain the same minimum number defined by that required by the plurality of first rolls: their number must not be modified / increased.
  • the extensions must also not be interchanged and thus the operations to interchange the built cassette assemblies are greatly reduced.
  • Figure 1 shows a top view of a planing unit according to the invention comprising a first cassette assembly (C1) provided with first leveling rollers (R1) being individually driven via extensions (A1) to a motorization unit (Re1, Ac1, M1, Re2, Ac2, M2).
  • first cassette assembly C1
  • R1 first leveling rollers
  • A1 motorization unit
  • Figure 2 shows a top view of a planing unit according to the invention comprising a second cassette assembly (C2) provided with second leveling rollers (R2) being driven via the same extensions (A1) by the same motorization group as to the figure 1 .
  • C2 second cassette assembly
  • R2 second leveling rollers
  • Figure 3 shows a top view of a planing unit according to the invention comprising a second set of cassettes (C2) provided with a mixture of first and second leveling rollers (R1, R2) being driven via the same extensions (A1) by the same group of motorization as at the figure 1 or 2 .
  • the motorization unit drives a plurality of motor torque transmission outputs on each of the extensions (A1) and comprises a motor assembly (M1, M2), a coupling assembly (Ac1, Ac2) and, at the output, an assembly torque reducer (Re1, Re2) connected to the extensions.
  • each motor, coupling and gearbox / gearbox assembly was split as an example (see Figure 5A , front view) according to a diagram with 4 and 5 torque transmission outputs in order to achieve a distribution of torque on 4 or 5 elongates driving the planing rollers. Any other configuration of the motorisation group is however possible.
  • figure 4 presents an individual drive configuration of each R1 rollers with single motor drive (M1, M2, M3, ...) and individually coupled (via coupling and gearbox Ac, Re also individual) on each of the extensions (A1) which allows to be able to exert relative differences between the various engine couples as flexibly as possible on each of the extensions.
  • the motorization (according to distinct branches motor / coupler / reducer) can thus include a means of distribution of couples to the elongations according to dimensional characteristics, mechanical properties and flatness of planar product and the configuration of Arrangement of the cassette rack assembly (C1) or (C2) coupled.
  • interchanging a set of cassettes with another according to the Figures 1 to 4 does not require the introduction or removal of a new element (intermediate drive, torque multiplier / torque outputs, ...) between the elements in each of the extension branches, reducer, coupler, motor.
  • the extensions can remain attached to the motorization unit.
  • Figures 5A and 5B respectively represent a front and side view of a planing unit comprising a first cassette assembly (C1), the extensions and the motorization according to the figure 1 .
  • the Figure 5A includes only the first rolls (R1) of the upper cassettes and of the cassette assembly (C1) shown in FIG. Figure 5B .
  • the cassette assembly (C1) comprises four upper leveling rollers and five lower leveling rollers laterally offset from the upper rollers.
  • the leveling rollers are rotatably mounted on each upper and lower part of the cassette frame (C1) by means of bearings (P1) supporting them at their ends.
  • Each end of the planing rollers, said first rollers (R1) having a first diameter (D1), is driven by an extension (A1), itself driven by the motorization unit according to the figure 1 or 4 , said engine group distributing an individual engine torque on each of the extensions resulting in the upper and lower planing rollers.
  • Figures 6A, 6B respectively show a front and side view of a planing unit comprising a second cassette assembly (C2) having been interchanged with the cassette assembly (C1) Figures 5A and 5B , extensions and motorization according to the figure 2 or 4 .
  • the second set of cassettes (C2) according to Figure 6A understands unlike Figure 5A eight planing rollers in part of upper frame and ten planing rollers in part of lower frame. These leveling rollers, called second rollers, have a second diameter (D2) smaller than the first diameter (D1) of the first rollers (R1) according to the FIG. 5A or 5B .
  • the first rollers are capable of hovering strips or plates of material of greater thickness than those hung by the second rollers.
  • the second rollers (R2) are rotatably mounted on each upper and lower part of the second cassette assembly (C2) by means of bearings (P2) supporting them at their ends.
  • bearings (P2) supporting them at their ends.
  • each first roll (R1) comprises a portion of sufficient length to place its bearing (P1), but also of sufficient length to allow the second set of cassettes (C2) to be sized exactly as the first set cassettes (C1) place his bearing (P1) while allowing to have the second bearing (P2) and a module torque distribution (MDC1, MDC2) in the portion provided (initially for the first rollers) but each end driven second roller (R2).
  • This leveling unit thus allows the cassette assemblies (C1, C2) to be dissociable from the set of (N1) extensions so that their exchange is carried out while maintaining all (N1) integral extensions. of the motorization.
  • the exchange is simplified and moreover, it is not necessary to change the number or type of extensions. It is only necessary to uncouple the extensions of the ends of the rollers so after replacement of a new set of cassettes to re-couple the extensions on the ends to be driven from the torque distribution module.
  • the leveling equipment provides that ends of the elongation sleeves (A1) closest to the two sets of cassettes (C1, C2) and assumed for the first set of cassettes cassette (C1) horizontal (see Figure 5B ) are movable and held in position in two dimensions in a vertical and / or horizontal plane to allow coupling to either a first roll end (see Figure 5B ), either on a drive input of a torque distribution module according to the steps and the altitude between rollers (see Figure 6B ).
  • This aspect is clearly visible through the Figure 6B in which it is notable that while the motorization unit is unchanged, the extensions (A1) are vertically displaced to be fixed in the drive input of each of the two lower and upper torque distribution modules (MDC1, MDC 2).
  • the extensions thus optimally comprise at their ends sleeve connectors connecting them to the shaft of the extension and provided with universal joint-type ball joints, which more generally are of the type allowing angular movement.
  • Each torque distribution module (MDC, MDC1, MDC2, etc.) comprises at least two profiled hollow shaft coupling outputs for enabling transmission of torque from an extension to two adjacent rollers (R2), each of the outputs being trapped on a portion of the end of said second rollers (R2) adapted to the same coupling profile (adjacent rollers, see Figure 6A ).
  • the planing equipment according to the invention also provides that at least one of said torque distribution modules (MDC) is mounted floating relative to the bearings (P2) for holding the rollers (R2) and the cassette assembly ( C2) in that it is equipped with an input shaft with profiled end to allow the transmission of torque and allowing coupling and uncoupling by simple introduction on the female sleeve of driving elongation (A1) located vis-à-vis -screw.
  • MDC torque distribution modules
  • P2 bearings
  • R2 rollers
  • C2 cassette assembly
  • the second cassette assembly (C2) including at least two of the second rollers (R2) associated with a torque distribution module (MDC), has the same fastening interfaces and connections as the first set cassette assembly (C1) equipped first rolls (R1).
  • These fasteners and connections are intended in particular connections to the extensions as seen above, but also any other electrical or fluid interfacing. This aspect is all the more facilitated since the frames of interchangeable cassette assemblies are of the same size and even if the positions of the drive entries are slightly displaced between said frames, at least one end of the extensions can be repositioned transversely accordingly .
  • the leveling equipment according to the invention also provides that the first and second cassette assemblies (C1, C2) have exactly dimensioned bearing arrangements at least at one end of the first and second rollers for positioning the first and second second rolls in cassette assemblies cassettes of identical external dimensions and, as already mentioned, for at least one torque distribution module so that the working table lengths of the first and second leveling rolls are almost similar, or identical.
  • the leveling equipment according to the invention can analogically to the preceding examples illustrated by the figures provide that the number of outputs of the torque distribution module (s) (MDC) can vary from 2 to 4. Indeed, depending on the engines and their torque delivered for strong first diameters (D1) of the first rollers, if the second set of cassettes (C2) requires, for reasons of planing process, a number of second rolls diameters (D2) in an amount greater than 2 and / or having a said diameter (D2) smaller than the first diameter (D1), the number of outputs of the torque distribution module on the second rollers is also increased as a function of the number of second rolls, so that the number of extensions is advantageously constant for all cassette rack assembly configurations and roll diameters thereof.
  • planing assembly according to the invention may also comprise a second cassette frame assembly (C2) being designed to admit a mixture of arrangement of first rollers (R1) and second rollers (R2) coupled to at least one module torque distribution (MDC).
  • MDC module torque distribution
  • the leveling equipment provides that the motor, that is to say the motor, the coupler and the gearbox, comprises a means of controlled distribution of individual torque towards each of the extensions according to dimensional characteristics. , mechanical properties and flatness of the planar product as well as the arrangement configuration of the cassette frame assembly (C1) or (C2) coupled.
  • An ideal embodiment of the motorization group thus provides that each extension is coupled to a single motor drive, the latter delivering a torque instantly controllable according to the required planing conditions.
