Definitions
- the present invention is in the field of working with materials by deformation and it relates more particularly to improvements in machines for bending flat sheets to conform them into cylinders or cones; these machines are commonly called rollers.
- rollers are known in which the bending of the sheet metal results from the passage of the latter between a so-called support roller and a train of crenellated rollers with axes parallel to the axis of the previous one and generally located at- above him; the cylindrical surfaces of the crenellated rollers interpenetrate and the bending radius is defined by the more or less close position of the support roller of all the crenelated rollers.
- the main problem posed by rolling machines is that of the bending of the rollers, and in particular of the support roller whose behavior can be analyzed like that of a necessarily long and thin beam; one solution to this problem consisted in imposing a corresponding flexion on the opposing rollers, in this case the crenellated rollers. It has therefore been proposed as a means of this solution, but also for other reasons, the use of a pressure roller with a diameter comparable to that of the support roller and rollers exerting a differentiated pressure on the pressure roller can be bent and thanks to which still the crenellated rollers only transmit the pressure of the pressure roller without their bearings being subjected to a considerable effort.
- one of the aims of the present invention is to provide a rolling machine with automatic operation, which can be associated with a welder working behind it and also working automatically; another object of the invention is to propose means for more precise adjustment of the flexion imposed on the crenellated rollers to compensate for the flexion of the support roller; another object is to distribute the load imposed on the crenellated rollers while guiding them in rotation in order to further reduce the load on their bearings.
- a machine intended to conform a flat sheet metal into a cone or cylinder a so-called “rolling machine” or “bending machine” is characterized by the combination of characteristics according to claim 1.
- the contact line of the pressure rollers with the crenellated rollers is located approximately 45 ° above the plane defined by the axes of the crenelated rollers.
- the adjustment of the rolling radius results from a precise vertical displacement of said set of rollers perpendicular to their axes, this displacement being induced by a displacement parallel to the axes of the rollers of a first ramp (at less) bearing on the one hand on a frame of the machine and on the other hand on a second ramp (at least) integral with the bearings of axes of the rollers of the mobile assembly.
- This characteristic results in better reproducibility of the positioning of the rolled sheet at the end of the operation, which ultimately promotes the automation of operations.
- a plurality of first ramps is formed in the edge of a bar, called ramps, while an identical plurality of second ramps is formed by so-called "sloping" calles integral with said movable beam; a good value for the angle formed by the plane of each ramp and the roller axes is approximately 6 ° (slope of approximately 10%); each sloping wedge comprises independent means of positioning in a direction parallel to that of the axes of the rollers.
- the means for positioning a sloping wedge are constituted by a plane slide parallel to the plane of the axes of the crenellated rollers, and oriented at approximately 45 ° relative to the direction of these axes.
- the displacement of the ramp bar in the direction of the axis of the rollers is caused by a jack fixed to the frame, jack whose rod is connected to said bar by pairs of tie rods and crosspieces, the "out" position. of the rod corresponding to the "lowered” position of the roller assembly while a stop limiting the exit of the rod is mounted at the end of a threaded shaft meshing in a nut of a gantry secured to the frame, the threaded shaft with a crank handle.
- the comb serves as a guide surface for the flat sheets before their passage between the rollers; a notch with a width at least equal to that of said bearing support veil is disposed at the end of each tooth on the side opposite to said guide surface; the end of each harpoon has at its upper part a small projecting rim; finally the comb is supported by a frame articulated at each of its ends around the support roller.
- a rolling machine of the prior art such as that described in the publication FR-A-2,528,335 comprises a support roller 1, two serrated rollers 2 and 3 and a single pressure roller 4, at the difference, appearing well by approximation of fig.3, the rolling machine of the present invention.
- a rolling machine of the invention consists of a fixed frame comprising mainly a veil-beam upper-5, two gantries, front-6 and rear 7, a veil-support-8 bearing-9, a pair of guide rails 10. It also consists of mobile parts comprising a support roller 11, only mobile in rotation, and a mobile assembly 12 including a beam 21 and the crenellated rollers (13,14) and support ( 15, 16, 17).
- the beam 21 is suspended from the web-beam 5 by suspensions with springs 23 and rods 24; wedges, called “sloping" 25 are fixed to the upper wing of the beam, which is advantageously an H-beam, facing ramps 26 cut in the edge of a bar 27, called ramps, and are permanently biased against the latter by the springs 23; the ramp bar 27 can slide in slides 28 parallel to the axes of the rollers (ie horizontally in the case of the machine in the figures), the sliding of the bar inducing a sliding of the ramps against the wedges and a vertical movement of the latter and of the mobile assembly 12 to which they are integral; there will be slides 29 for vertical guide of the assembly 12.
- a motor-reduction unit 30 for driving the support roller 11 and on the other hand a set 31 of means intended for adjusting the bending radius of the sheets; these means 31 comprise a jack 32 whose body is integral with the gantry 7 and whose rod 33 is connected to a first cross member 34 which is itself connected by a couple of tie rods 38 to a second cross member 39 which is itself secured to the bar ramps 27.
- a threaded shaft 40 coaxial with the rod 33 is supported by a secondary frame 41 secured to the main frame (5,7); a first end of the shaft supports, or forms, a stop 42 to limit the exit of the rod 33, while its other end supports a crank 43 indexable and provided with a position indicator.
- each wedge is constituted by a prismatic block 50, of anti-friction metal for example, shaped at its base, in dovetail for example, to be able to be guided in sliding in a slide 51 of corresponding shape, formed in a base 52 fixed on the beam 21;
- the slide as is clearly visible in fig.6 is oriented at about 45 ° relative to the direction of the axes of the rollers, or even relative to the direction of sliding of the ramp bar;
- the adjustment of the position of the wedge along its slide is effected by means of two coaxial and antagonistic screws 53, screwed in nuts 54 secured to the base, and the ends of which bear on flats 55 of the block;
- the upper face of the block forms an inclined plane 56 parallel to the face of the ramps; for reasons of convenience and simplification of machining, the planes of the sides of the ramp are perpendicular to the median longitudinal plane of the ramp bar and, necessarily parallel to one another; it follows from this arrangement that sliding over a
- the inclination of the plane of the ramps and the shims is approximately 6 ° relative to the direction of the axes of the rollers (that is, a slope of approximately 10% relative to the direction of sliding of the ramp bar); it follows from this slope value, that the vertical displacement of the movable assembly 12 is ten times smaller than the movement of the ramp bar 21 which causes it.
- a quarter turn of the crank 43 will have the effect of modifying the stroke of the bar by one millimeter and the stroke of the mobile assembly by one tenth of a millimeter; this precision is not excessive since it conditions the obtaining of the desired bending radius, and therefore the proper functioning of the subsequent automations.
- improved means participating in the loading (introduction of the sheet between the rollers) and in the unloading include a set, called comb 60, of teeth 61, also called harpoons because of their shape and their function , supported by a U-shaped frame 62, the arms 63 of which are articulated on and at the ends of the support roller 11; jacks 64 are engaged on extensions 65 of arms 63 to impart to them a pivoting movement around the axis of the roller 11 (arrows 70).
- Each tooth, or harpoon 61 has a notch 66 at the bottom and at the rims of its end and, at the upper part of its end, a protruding rim 67.
- the width 1 ′ of the notches 66 is equal to or slightly greater than l thickness 1 ⁇ of the support veil 8 of the bearing 9. It will be noted, in FIG. 5, that the plane 68 formed by the upper face of the harpoons is substantially tangent to the roller 11 and that the line of tangency is very close to the contact line of the serrated rollers 14 when the chassis 62 is in the low position, while the notches, also tangent to the roller 11, are aligned with the support web 8 when the chassis is in the raised position.
- the comb serves as a table for guiding the sheets T in the direction of the rollers; thus again, in the high position and at the end of the cycle (fig. 8c and 8d) the notches keep the straight edges of the rolled sheets separate and align these edges on each side of the support veil.
- the pivoting of the chassis limited by adjustable stops 71,72 (fig.4), is very precise and this precision allows the automatic extraction of the sheet after rolling.
- This extraction is carried out by a pusher 75 grazing the underside of the support roller 11; the pusher is supported by a carriage 76 driven back and forth by a pair of chains 77 in the rails 10; the standby position of the extractor is that shown in fig.1.
- the rolling machine of the invention operates the bending in a single pass, and the consecutive automatic ejection, thanks to the precise positioning of the harpoons, leads to a duration of the cycle of an operation, considerably reduced; the precision of the bending radius and that of the parallelism of the straight edges facing (edges) makes it possible to couple directly to the machine (that is to say without intermediate handling) any automatic welder of ferrules.
- the means 31 intended for adjusting the bending radius could be automatic means indexed to the angular position in rotation of the support roller 11 which is also a driving roller, whereby the bending radius can vary during a cycle to obtain a more or less elliptical or working cylinder.
- These means can be, for example, of the cylinder type supplied through servo-valves, or else with ball screws for the operation of the ramp bar and DC motor; the control of the adjustment means will then preferably be of the digital type. Obviously the control could also be of analog type by a mechanical transmission of the movement of the support roller to the ramp bar.

Description
La présente invention est du domaine du travail des matériaux par déformation et elle a plus particulièrement pour objet des perfectionnements aux machines de cintrage des tôles plates pour les conformer en cylindre ou en cône ; ces machines sont communément appellées rouleuses.The present invention is in the field of working with materials by deformation and it relates more particularly to improvements in machines for bending flat sheets to conform them into cylinders or cones; these machines are commonly called rollers.
On rappelle que l'on connait des rouleuses dans lesquelles le cintrage de la tôle résulte du passage de cette dernière entre un rouleau dit d'appui et un train de rouleaux crénelés d'axes parallèles à l'axe du précédent et généralement situé au-dessus de lui ; les surfaces cylindriques des rouleaux crénélés s'interpénêtrent et le rayon de cintrage est défini par la position plus ou moins rapprochée du rouleau d'appui de l'ensemble des rouleaux crénelés.It will be recalled that rollers are known in which the bending of the sheet metal results from the passage of the latter between a so-called support roller and a train of crenellated rollers with axes parallel to the axis of the previous one and generally located at- above him; the cylindrical surfaces of the crenellated rollers interpenetrate and the bending radius is defined by the more or less close position of the support roller of all the crenelated rollers.
On connaît aussi une publication FR-A-1 306 612 NOJIMA qui décrit une rouleuse à rouleaux verticaux dans laquelle les rouleaux presseurs sont segmentés et répartis en plusieurs trains de rouleaux coaxiaux ; cette machine dans laquelle les rouleaux presseurs ne sont pas crénelés semble destinée au roulage à la fabrication à partir de tôles épais ses de viroles d'assez grand diamètre.Also known is a publication FR-A-1 306 612 NOJIMA which describes a vertical roller rolling machine in which the pressing rollers are segmented and distributed in several trains of coaxial rollers; this machine in which the pressure rollers are not crenellated seems intended for rolling in manufacturing from thick sheets of ferrules of fairly large diameter.
Le principal problème posé par les rouleuses est celui de la flexion des rouleaux, et particulièrement du rouleau d'appui dont le comportement s'analyse comme celui d'une poutre nécessairement assez longue et mince ; une solution de ce problème a consisté à imposer une flexion correspondante aux rouleaux antagonistes, dans le cas présent les rouleaux crénelés. On a donc proposé comme moyen de cette solution, mais aussi pour d'autres raisons, l'emploi d'un rouleau presseur d'un diamètre comparable à celui du rouleau d'appui et de galets exerçant une pression différenciée sur le rouleau presseur peut être infléchi et grâce à quoi encore les rouleaux crénelés ne font que transmettre la pression du rouleau presseur sans que leurs paliers subissent un effort considérable.The main problem posed by rolling machines is that of the bending of the rollers, and in particular of the support roller whose behavior can be analyzed like that of a necessarily long and thin beam; one solution to this problem consisted in imposing a corresponding flexion on the opposing rollers, in this case the crenellated rollers. It has therefore been proposed as a means of this solution, but also for other reasons, the use of a pressure roller with a diameter comparable to that of the support roller and rollers exerting a differentiated pressure on the pressure roller can be bent and thanks to which still the crenellated rollers only transmit the pressure of the pressure roller without their bearings being subjected to a considerable effort.
Cet art antérieur est bien décrit dans des publications FR-A 2 411 647 et FR-A 2 528 335 (& EP-A-0 096 643), toutes deux au nom de la présente demanderesse. La rouleuse, comportant les perfectionnements de la dernière publication, a donné d'excéllents résultats quant à la précision du rayon de centrage obtenu ; cependant par le fait du déplacement bi-axial des trains de rouleaux crénelés la machine se prêtait mal à un travail à grande productivité. En outre et en raison de la forme d'un organe, dit harpon, le positionnement, après roulage, des bords rectilignes des tôles, n'était pas suffisamment précis.This prior art is well described in publications FR-A 2 411 647 and FR-A 2 528 335 (& EP-A-0 096 643), both in the name of the present applicant. The rolling machine, incorporating the improvements of the last publication, has given excellent results as regards the precision of the centering radius obtained; however due to the bi-axial displacement of the crenellated roller trains the machine did not lend itself to high productivity work. In addition and due to the shape of a body, called a harpoon, the positioning, after rolling, of the straight edges of the sheets, was not sufficiently precise.
Or, l'un des buts visés par la présente invention est de proposer une rouleuse à fonctionnement automatique, pouvant être associée à une soudeuse travaillant derrière elle et travaillant aussi de façon automatique ; un autre but de l'invention est de proposer des moyens de réglage plus précis de la flexion imposée aux rouleaux crénelés pour compenser la flexion du rouleau d'appui ; un autre but est de répartir la charge imposée aux rouleaux crénelés tout en les guidant en rotation afin de diminuer encore la charge de leurs paliers.However, one of the aims of the present invention is to provide a rolling machine with automatic operation, which can be associated with a welder working behind it and also working automatically; another object of the invention is to propose means for more precise adjustment of the flexion imposed on the crenellated rollers to compensate for the flexion of the support roller; another object is to distribute the load imposed on the crenellated rollers while guiding them in rotation in order to further reduce the load on their bearings.
Selon la présente invention une machine destinée à conformer en cône ou en cylindre une tôle plate, machine dite "rouleuse" ou "cintreuse", est caractérisée par la combinaison de caractéristiques selon la revendication 1. De préférence la ligne de contact des rouleaux presseurs avec les rouleaux crénelés est située à environ 45° au-dessus du plan défini par les axes des rouleaux crénelés.According to the present invention, a machine intended to conform a flat sheet metal into a cone or cylinder, a so-called "rolling machine" or "bending machine", is characterized by the combination of characteristics according to claim 1. Preferably the contact line of the pressure rollers with the crenellated rollers is located approximately 45 ° above the plane defined by the axes of the crenelated rollers.
Il résulte des caractéristiques sus-énumérées, et notamment de la première, une répartition plus judicieuse de l'effort et une décharge importante des paliers des rouleaux crénelés.It results from the abovementioned characteristics, and in particular from the first, a more judicious distribution of the force and a significant discharge of the bearings of the crenellated rollers.
Selon une autre caractéristique préferée de l'invention le réglage du rayon de roulage résulte d'un déplacement vertical précis dudit ensemble de rouleaux perpendiculairement à leurs axes, ce déplacement étant induit par un déplacement parallèle aux axes des rouleaux d'une première rampe (au moins) prenant appui d'une part sur un bâti de la machine et d'autre part sur une seconde rampe (au moins) solidaire des paliers d'axes des rouleaux de l'ensemble mobile. Il résulte de cette caractéristique une meilleure reproductibilité du positionnement de la tôle roulée en fin d'opération, ce qui en définitive favorise l'automatisation des opérations.According to another preferred characteristic of the invention, the adjustment of the rolling radius results from a precise vertical displacement of said set of rollers perpendicular to their axes, this displacement being induced by a displacement parallel to the axes of the rollers of a first ramp (at less) bearing on the one hand on a frame of the machine and on the other hand on a second ramp (at least) integral with the bearings of axes of the rollers of the mobile assembly. This characteristic results in better reproducibility of the positioning of the rolled sheet at the end of the operation, which ultimately promotes the automation of operations.
Avantageusement encore une pluralité de premières rampes est ménagée dans le bord d'une barre, dite de rampes, tandis qu'une pluralité identique de secondes rampes est contituée par des calles dites "pentées" solidaires de la dite poutre mobile ; une bonne valeur de l'angle formé par le plan de chaque rampe et les axes de rouleau est d'environ 6° (pente d'environ 10%) ; chaque cale pentée comporte des moyens indépendants de positionnement dans une direction parallèle à celle des axes des rouleaux. Suivant une forme particulière de realisation, les moyens de posisionnement d'une cale pentée sont constitués par une glissière de plan parallèle au plan des axes des rouleaux crénelés, et orientée à 45° environ par rapport à la direction de ces axes.Advantageously also, a plurality of first ramps is formed in the edge of a bar, called ramps, while an identical plurality of second ramps is formed by so-called "sloping" calles integral with said movable beam; a good value for the angle formed by the plane of each ramp and the roller axes is approximately 6 ° (slope of approximately 10%); each sloping wedge comprises independent means of positioning in a direction parallel to that of the axes of the rollers. According to a particular embodiment, the means for positioning a sloping wedge are constituted by a plane slide parallel to the plane of the axes of the crenellated rollers, and oriented at approximately 45 ° relative to the direction of these axes.
Il résulte de ces dernières dispositions une possibilité de réglage précis et pratique du rayon de cintrage d'une part et de la compensation de flexion du rouleau d'appui, d'autrepart.It follows from these latter arrangements a possibility of precise and practical adjustment of the bending radius on the one hand and of the compensation of bending of the support roller, on the other hand.
Avantageusement le déplacement,de la barre de rampes dans le sens de l'axe des rouleaux est provoqué par un verin solidaire du bâti, verin dont la tige est reliée à la dite barre par des couples de tirants et traverses, la position "sortie" de la tige correspondant à la position "abaissée" de l'ensemble de rouleaux tandis qu'une butée limitant la sortie de la tige est montée en bout d'un arbre fileté engrenant dans un écrou d'un portique solidaire du bâti, l'arbre fileté comportant une manivelle indéxable.Advantageously, the displacement of the ramp bar in the direction of the axis of the rollers is caused by a jack fixed to the frame, jack whose rod is connected to said bar by pairs of tie rods and crosspieces, the "out" position. of the rod corresponding to the "lowered" position of the roller assembly while a stop limiting the exit of the rod is mounted at the end of a threaded shaft meshing in a nut of a gantry secured to the frame, the threaded shaft with a crank handle.
D'autres dispositions caractéristiques s'appliquent à la disposition connue dans son principe d'un peigne mobile en rotation dont les dents sont tangentes au rouleau d'appui, et peuvent par rotation du peigne autour de l'axe du rouleau d'appui, pénêtrer entre les rouleaux crénelés pour séparer les bords rectilignes des tôles roulées. Suivant ces dispositions caractéristiques le peigne sert de surface de guidage aux tôles plates avant leur passage entre les rouleaux; un cran d'une largeur au moins égale à celle dudit voile-support de palier est disposé à l'extrémité de chaque dent du côté opposé à la dite surface de guidage; l'extrémité de chaque harpon comporte à sa partie supérieure un petit rebord en saillie; enfin le peigne est supporté par un cadre articulé à chacune de ses extrémités autour du rouleau d'appui.Other characteristic arrangements apply to the arrangement known in principle of a comb movable in rotation whose teeth are tangent to the support roller, and can by rotation of the comb around the axis of the support roller, penetrate between the crenellated rollers to separate the straight edges from the rolled sheets. According to these characteristic arrangements, the comb serves as a guide surface for the flat sheets before their passage between the rollers; a notch with a width at least equal to that of said bearing support veil is disposed at the end of each tooth on the side opposite to said guide surface; the end of each harpoon has at its upper part a small projecting rim; finally the comb is supported by a frame articulated at each of its ends around the support roller.

Sur la fig.1 une rouleuse de l'art antérieur, telle que celle décrite dans la publication FR-A-2.528.335 comporte un rouleau d'appui 1, deux rouleaux crénelés 2 et 3 et un rouleau presseur 4 unique, à la différence ,apparaissant bien par rapprochement de la fig.3, de la rouleuse de la présente invention.In fig.1 a rolling machine of the prior art, such as that described in the publication FR-A-2,528,335 comprises a support roller 1, two serrated rollers 2 and 3 and a
Sur la fig.2 une rouleuse de l'invention est constituée d'un bâti fixe comprenant principalement un voile-poutre supérieur-5, deux portiques, avant-6 et arrière 7, un voile-support-8 de palier-9, un couple de rails de guidage 10. Elle est constituée aussi de parties mobiles comprenant un rouleau d'appui 11, uniquement mobile en rotation, et un ensemble mobile 12 incluant une poutre 21 et les rouleaux crénelés(13,14) et d'appui(15,16,17).On fig.2 a rolling machine of the invention consists of a fixed frame comprising mainly a veil-beam upper-5, two gantries, front-6 and rear 7, a veil-support-8 bearing-9, a pair of
Il apparaît bien sur la fig.2 que les rouleaux presseurs et les rouleaux crénelés sont conformés en une pluralité de trains coaxiaux engagés dans des paliers de plaques-support intermédiaires 18 et d'extrémités 19 ; Il apparaît aussi sur la fig.3 (voir aussi fig.5) que la ligne de contact des rouleaux presseurs-15,17 avec les rouleaux crénelés-13,14 est située à 45° environ au-dessus du plan 20 défini par les axes des rouleaux crénelés.It appears clearly in FIG. 2 that the pressure rollers and the crenellated rollers are shaped in a plurality of coaxial trains engaged in bearings of
Toujours sur la fig.2, il apparaît que la poutre 21 est suspendue au voile-poutre 5 par des suspensions à ressorts 23 et tiges 24; des cales, dites "pentées" 25 sont fixées à l'aile supérieure de la poutre, qui est avantageusement une poutre en H, en regard de rampes 26 taillées dans le bord d'une barre 27, dite de rampes, et sont en permanence sollicitées en appui contre ces dernières par les ressorts 23; la barre de rampes 27 peut coulisser dans des coulisses 28 parallèlement aux axes des rouleaux (soit horizontalement dans le cas de la machine des figures), le coulissement de la barre induisant un glissement des rampes contre les cales et un mouvement vertical de ces dernières et de l'ensemble mobile 12 dont elles sont solidaires; on remarquera des glissières 29 de guidage vertical de l'ensemble 12.Still on fig.2, it appears that the
Sur la partie droite de la fig.2 on a représenté d'une part un groupe moto-réducteur 30 d'entrainement du rouleau d'appui 11, et d'autre part un ensemble 31 de moyens destinés au réglage du rayon de cintrage des tôles; ces moyens 31 comprennent un vérin 32 dont le corps est solidaire du portique 7 et dont la tige 33 est reliée à une première traverse 34 elle-même reliée par un couple de tirants 38 à une seconde traverse 39 elle-même solidaire de la barre de rampes 27. Un arbre fileté 40 coaxial à la tige 33 est supporté par un bâti secondaire 41 solidaire du bâti principal(5,7); une première extrémité de l'arbre supporte, ou forme, une butée 42 pour limiter la sortie de la tige 33, tandis que son autre extrémité supporte une manivelle 43 indexable et munie d'un indicateur de position.On the right side of FIG. 2 is shown on the one hand a motor-
Sur la partie gauche de la fig.2 on a symbolisé, en tirets, une autre machine, telle qu'une soudeuse, pouvant travailler à la suite et en synchronisme, avec la rouleuse de la figure.On the left-hand side of fig. 2 we have symbolized, in dashes, another machine, such as a welder, which can work in succession and in synchronism with the rolling machine of the figure.
Suivant le mode avantageux de réalisation des cales illustré sur les fig.5 et 6, chaque cale est constituée par un bloc 50 prismatique, de métal antifriction par exemple, conformé à sa base, en queue d'aronde par exemple, pour pouvoir être guidé en coulissement dans une glissière 51 de forme correspondante, ménagée dans un socle 52 fixé sur la poutre 21; la glissière, comme cela est bien visible sur la fig.6 est orientée à environ 45° par rapport à la direction des axes des rouleaux, ou encore par rapport à la direction de coulissement de la barre de rampes; le réglage de la position de la cale le long de sa glissière est opéré au moyen de deux vis 53 coaxiales et antagonistes, vissées dans des écrous 54 solidaire de socle, et dont les extrémités prennent appui sur des méplats 55 du bloc; la face supérieure du bloc forme un plan incliné 56 parallèle à la face des rampes; pour des raisons de commodité et de simplification de l'usinage les plans des faces des rampe sont perpendiculaires au plan longitudinal médian de la barre de rampe et, nécéssairement parallèle entre eux; il découle de cette disposition qu'un coulissement sur une distance d du bloc dans la glissière est équivalent à un coulissement de valeur 0,7d effectué dans le plan de la barre de rampes; il en résulte en défintive une petite démultiplication favorable à la précision du réglage, et une meilleure accéssibilité des moyens de réglage. L'inclinaison du plan des rampes et des cales est d'environ 6° par rapport à la direction des axes des rouleaux (soit encore une pente d'environ 10% par rapport à la direction de coulissement de la barre de rampes); il résulte de cette valeur de pente, que le déplacement vertical de l'ensemble mobile 12 est dix fois plus petit que le mouvement de la barre de rampes 21 qui le provoque. A titre d'exemple, un quart de tour de la manivelle 43 aura pour effet de modifier la course de la barre d'un millimetre et la course de l'ensemble mobile d'un dixième de millimetre; cette précision n'est pas excéssive puisqu'elle conditionne l'obtension du rayon de cintrage désiré, et de ce fait le bon fonctionnement des automatismes ultérieurs.According to the advantageous embodiment of the wedges illustrated in FIGS. 5 and 6, each wedge is constituted by a
Sur les fig.4 et 5, des moyens perfectionnés participant au chargement (introduction de la tole entre les rouleaux) et au déchargement comprennent un ensemble, dit peigne 60, de dents 61, dites aussi harpons en raison de leur forme et de leur fonction, supporté par un châssis en U 62 dont les bras 63 sont articulés sur, et aux extrémités, du rouleau d'appui 11; des vérins 64 sont en prise sur des prolongements 65 des bras 63 pour leur communiquer un mouvement de pivotement autour de l'axe du rouleau 11 (flêches 70). Chaque dent, ou harpon 61, comporte au dessous et au vosinage de son extrémité un cran 66 et, à la partie supérieure de son son extrémité, un rebord en saillie 67. La largeur 1′ des crans 66 est égale ou légèrement supérieure à l'épaisseur 1˝ du voile-support 8 du palier 9. On remarquera, sur la fig.5, que le plan 68 constitué par la face suppérieure des harpons est sensiblement tangent au rouleau 11 et que la ligne de tangence est très voisine de la ligne de contact des rouleaux crénelés 14 lorsque le châssis 62 est en position basse, tandis que les crans, tangents aussi au rouleau 11, sont alignés avec le voile-support 8 lorsque le châssis est en position relevée.In FIGS. 4 and 5, improved means participating in the loading (introduction of the sheet between the rollers) and in the unloading include a set, called
Ainsi, en position basse et en début de cycle (fig.8a), le peigne sert de table guidage des tôles T en direction des rouleaux; ainsi encore, en position haute et en fin de cycle (fig.8c et 8d) les crans maintiennent séparés le bords rectilignes des tôles roulées et alignent ces bords de chaque côté du voile-support. Le pivotement du châssis, limité par des butées réglables 71,72(fig.4), est très précis et cette précision autorise l'extraction automatique de la tôle après roulage. Cette extraction est opérée par un pousoir 75 frôlant la face inférieure du rouleau d'appui 11; le poussoir est supporté par un chariot 76 entrainé en aller-retour par un couple de chaines 77 dans les rails 10; la position d'attente de l'extracteur est celle représentée en fig.1.Thus, in the low position and at the start of the cycle (fig.8a), the comb serves as a table for guiding the sheets T in the direction of the rollers; thus again, in the high position and at the end of the cycle (fig. 8c and 8d) the notches keep the straight edges of the rolled sheets separate and align these edges on each side of the support veil. The pivoting of the chassis, limited by adjustable stops 71,72 (fig.4), is very precise and this precision allows the automatic extraction of the sheet after rolling. This extraction is carried out by a
Ainsi grâce aux dispositions de l'invention on peut régler le rayon de cintrage des tôles par la manoeuvre d'un seul organe (la barre de rampes) ce qui supprime la nécessité d'un savoir-faire très empirique.So thanks to the provisions of the invention it is possible to adjust the bending radius of the sheets by the operation of a single member (the ramp bar) which eliminates the need for very empirical know-how.
En outre la rouleuse de l'invention opère le cintrage en une seule passe, et l'éjection automatique consécutive, grâce au positionnement précis des harpons, conduit à une durée du cycle d'une opération, considérablement réduite ; la précision du rayon de cintrage et celle du parallèlisme des bords rectilignes en regards (rives) permet d'accoupler directement à la machine (c'est-à-dire sans manutention intermédiaire) n'importe quelle soudeuse automatique de virolles.In addition, the rolling machine of the invention operates the bending in a single pass, and the consecutive automatic ejection, thanks to the precise positioning of the harpoons, leads to a duration of the cycle of an operation, considerably reduced; the precision of the bending radius and that of the parallelism of the straight edges facing (edges) makes it possible to couple directly to the machine (that is to say without intermediate handling) any automatic welder of ferrules.
On notera que les moyens 31 (fig.2) destinés au réglage du rayon de cintrage pourraient être des moyens automatiques indexés à la position angulaire en rotation du rouleau d'appui 11qui est aussi un rouleau moteur, grâce à quoi le rayon de cintrage pourra varier au cours d'un cycle pour permettre l'obtention d'un cylindre plus ou moins éliptique ou ouvale. Ces moyens peuvent être, par exemple, du type à verin alimenté à travers des servo-valves, ou encore à vis à billes pour la manoeuvre de la barre de rampes et moteur à courant continu ; la commande des moyens de réglage sera alors, de préférence, de type numérique. Bien évidemment la commande pourrait être aussi de type analogique par une transmission mécanique du mouvement du rouleau d'appui à la barre de rampe.It will be noted that the means 31 (FIG. 2) intended for adjusting the bending radius could be automatic means indexed to the angular position in rotation of the
