Description
Outil de façonnage par profilage de cannelures ou de rainures sur des pièces cylindriques.Tool for shaping by profiling grooves or grooves on cylindrical parts.
La présente invention concerne un outil de façonnage par profilage des rainures longitudinales, notamment des cannelures sur des pièces cylindriques, comportant des galets profilés montés à rotation dans un organe de réception, perpendiculairement à l'axe de la pièce.The present invention relates to a shaping tool by profiling longitudinal grooves, in particular grooves on cylindrical parts, comprising profiled rollers mounted for rotation in a receiving member, perpendicular to the axis of the part.
On connaît déjà des outils utilisés pour le laminage à froid de pignons et d'arbres cannelés. Lorsqu'on utilise des galets profilés, on prévoit un nombre de galets correspondant au nombre de dents ou de cannelures et qui sont amenés simultanément en contact avec la pièce. Les forces de laminage sont absorbées par les galets. Les paliers doivent donc être de dimensions suffisantes, ce qui exige des galets de dimensions correspondantes. Avec les dimensions des galets augmente également la surface en contact avec la pièce. Il en résulte aussi une augmentation de la force de laminage. Le rendement des outils connus est donc limité.Tools are already known for cold rolling pinions and fluted shafts. When profiled rollers are used, a number of rollers is provided corresponding to the number of teeth or splines and which are brought simultaneously into contact with the part. The rolling forces are absorbed by the rollers. The bearings must therefore be of sufficient dimensions, which requires rollers of corresponding dimensions. With the dimensions of the rollers also increases the surface in contact with the part. This also results in an increase in the rolling force. The performance of known tools is therefore limited.
On a déjà proposé dans un outil du type précité de monter pour chaque galet de profilage, des galets d'appui qui sont maintenus en butée avec la périphérie du galet de laminage Ces galets d'appui sont montés à rotation sur un organe de réception et absorbent donc les efforts radiaux qui sont transmis par la pièce aux galets profilés.It has already been proposed in a tool of the aforementioned type to mount for each profiling roller, support rollers which are held in abutment with the periphery of the rolling roller These support rollers are mounted for rotation on a receiving member and therefore absorb the radial forces which are transmitted by the part to the profiled rollers.
Un tel outil possède donc à la fois une multiplicité des galets profilés montés individuellement sur des axes calés et une multiplicité de galets d'appui. Ce dispositif ne décharge pas les paliers des galets d'appui et ne permet pas de réduire sensiblement les dimensions de l'outil.Such a tool therefore has both a multiplicity of profiled rollers individually mounted on fixed axes and a multiplicity of support rollers. This device does not discharge the bearings from the support rollers and does not make it possible to reduce the dimensions of the tool appreciably.
Le principe de l'invention consiste en un outil dans lequel on prévoit plusieurs galets profilés disposés en cercle autour de la pièce dans des logements d'une cage de retenue qui positionne angulairement les galets les uns par rapport aux autres, et en anneau cylindrique monté à déplacement axial dans un logement délimité entre deux bagues de retenue de l'ensemble constitué par la cage et des galets profilés, de manière que le dit anneau se déplace par coulissement et absorbe la force radiale agissant sur les galets profilés lors du façonnage des rainures.The principle of the invention consists of a tool in which several profiled rollers are provided arranged in a circle around the part in housings of a retaining cage which angularly positions the rollers relative to each other, and in a cylindrical ring mounted axially displaced in a housing delimited between two retaining rings of the assembly constituted by the cage and profiled rollers, so that said ring moves by sliding and absorbs the radial force acting on the profiled rollers during the shaping of the grooves .
Il existe également des dispositifs destinés à laminer des profils de dentures et comportant plusieurs outils de laminage disposés en cercle autour de la pièce. Ces outils prennent appui sur des languettes qui sont logées dans des rainures ménagées dans un corps de palier annu laire. #n même temps, les cylindres roulent sur les languettes. Les outils de laminage, ainsi que la pièce, se déplacent donc dans le sens du laminage.There are also devices intended to laminate teeth profiles and comprising several rolling tools arranged in a circle around the part. These tools are supported on tongues which are housed in grooves formed in an annular bearing body. #n the same time, the cylinders roll on the tabs. The rolling tools, as well as the workpiece, therefore move in the rolling direction.
Les supports des galets des outils suivant l'invention sont par contre immobiles dans le sens du travail, ou bien mobiles par rapport a un poinçon fixe. Les outils établis suivant l'invention-ne nécessitent aucune construction spéciale, donc coûteuse, et peuvent être utilisés sur chaque presse du commerce.The supports of the rollers of the tools according to the invention are on the other hand immobile in the direction of work, or else movable relative to a fixed punch. The tools established according to the invention do not require any special construction, therefore costly, and can be used on each commercial press.
D'autres particularités apparaîtront à la lecture de la description qui va suivre, faite en regard des dessins schématiques annexés montrant, à titre d'exemples non limitatif, un mode de réalisation possible de l'objet de l'invention.Other particularities will appear on reading the description which follows, made with reference to the appended schematic drawings showing, by way of nonlimiting examples, a possible embodiment of the subject of the invention.
La fig. l est une vue en coupe longitudinale partielle par la ligne
I-I en fig. 2.Fig. l is a view in partial longitudinal section through the line
II in fig. 2.
La fig. 2 est une vue en plan partielle avec une coupe partielle suivant la ligne II-II en fig. l. Fig. 2 is a partial plan view with a partial section along the line II-II in FIG. l.
Sur la figure l et 2, on a désigné par l le poinçon qui peut être actionné par une presse non représentée. Le poinçon l est fixé à la plaque de support 2 au moyen de vis 3. L'extrémité du poinçon est conformée en un mandrin profilé i a qui présente un profil extérieur correspondant au profil intérieur de la pièce après façonnage. Sur le mandrin la est placée la pièce à façonner 4 qui est immobilisée à titre d'exemple axialement sur le mandrin par une plaque de maintien 5 au moyen de vis 6.In FIGS. 1 and 2, the punch is designated by l which can be actuated by a press, not shown. The punch l is fixed to the support plate 2 by means of screws 3. The end of the punch is shaped into a profiled mandrel i a which has an external profile corresponding to the internal profile of the part after shaping. The workpiece 4 is placed on the mandrel which is immobilized, for example, axially on the mandrel by a retaining plate 5 by means of screws 6.
Sur une plaque porte-outil 7 est fixée, concentriquement par rapport à l'axe longitudinal du poinçon 1 et du mandrin la, au moyen de vis 8 une bague de retenue 9 désignée ci-après bague supérieure1'. La bague supérieure a une section conformée en U dont les branches latérales 9a, 9b délimitent une partie du logement 10 d'un anneau de contrainte 11. La bague supérieure est accolée par une branche latérale 9a à la branche correspondante 12a d'une bague de retenue 12 désignée ci-après "bague inférieure". Les bagues de retenue 9,12 portent des branches latérales 9b, 12b espacées l'une de l'autre et destinées à la rétention d'une cage 13 à logements 14 régulièrement espacés à la périphérie de la dite cage dont chacun contient un galet profilé 15.Les logements 14 positionnent ainsi angulairement les galets 15 dont le nombre correspond à celui des cannulures ou rainures à façonner. Les galets 15 sont montés à rotation sans jeu entre les faces parallèles du logement correspondant. Le sommet du profil des différents galets est intérieurement en appui sur l'anneau cylindrique Il qui absorbe de la sorte la force radiale agissant sur l'ensemble des galets profilés lors du façonnage des rainures. L'anneau il est monté par ailleurs à déplacement axial dans le logement 10 et il est prévu un dispositif de rappel en position initiale de l'anneau Il. A cet effet un dispositif élastique tel que deux ressorts de rappel disposés en tension entre le fond du logement 10 et l'anneau Il pourrait convenir.Les branches qb, 12b peuvent également être à écartement variable dans le but de faciliter l'adaptation de l'outil à différentes dimensions de cages et-de galets.On a tool holder plate 7 is fixed, concentrically with respect to the longitudinal axis of the punch 1 and of the mandrel 1a, by means of screws 8 a retaining ring 9 hereinafter designated upper ring 1 ′. The upper ring has a U-shaped section, the lateral branches 9a, 9b delimiting part of the housing 10 of a constraint ring 11. The upper ring is joined by a lateral branch 9a to the corresponding branch 12a of a ring of retainer 12 hereinafter referred to as "lower ring". The retaining rings 9, 12 carry lateral branches 9b, 12b spaced from one another and intended for the retention of a cage 13 with housings 14 regularly spaced at the periphery of said cage, each of which contains a profiled roller 15.The housings 14 thus angularly position the rollers 15, the number of which corresponds to that of the grooves or grooves to be shaped. The rollers 15 are mounted for rotation without play between the parallel faces of the corresponding housing. The top of the profile of the various rollers is internally supported on the cylindrical ring II which thus absorbs the radial force acting on all of the profiled rollers during the shaping of the grooves. The ring it is also mounted to move axially in the housing 10 and there is provided a return device in the initial position of the ring II. For this purpose an elastic device such as two return springs arranged in tension between the bottom of the housing 10 and the ring It could be suitable. The branches qb, 12b can also be of variable spacing in order to facilitate the adaptation of the tool with different dimensions of cages and rollers.
Lors du fonctionnement de l'outil, la plaque porte-outil 7 et les galets 15 se déplacent dans le sens de la flèche P perpendiculairement à 1 des galets, jusqu'au contact avec la pièce 4 et le mouvement se continue jusqu'au formage complet des cannelures. Un dispsoitif hydraulique accessoire actionne l'éjecteur de la pièce 4 au cas où celle-ci n'est pas retenue par le système a' plaque et vis 5, 6 illustré. Selon une variante de fonctionnement la pièce 4 peut entre poussée et guidée entre les galets de la plaque porte~outil fixe. During the operation of the tool, the tool holder plate 7 and the rollers 15 move in the direction of the arrow P perpendicular to 1 of the rollers, until contact with the part 4 and the movement continues until forming. complete with grooves. An accessory hydraulic device operates the ejector of the part 4 in the event that it is not retained by the plate and screw system 5, 6 illustrated. According to a variant of operation, the part 4 can between thrust and guided between the rollers of the carrier plate ~ fixed tool.
