Abstract
Description
L'invention se rapporte à un dispositif pour nettoyer l'intérieur d'une lingotière. The invention relates to a device for cleaning the interior of an ingot mold.
Dans la sidérurgie, il est habituel de couler le métal ou l'alliage en fusion dans des lingotières pour le démouler ensuite afin d'obtenir, après solidification, des lingots de métal qui pourront être transportés sur d'autres sites afin d'être ouvrés ou refondus. In the steel industry, it is usual to cast the metal or the molten alloy in ingot molds and then unmold it in order to obtain, after solidification, metal ingots which can be transported to other sites in order to be worked or recast.
Ces lingotières sont des moules de sections sensiblement prismatiques dont les faces se raccordent par de faibles arrondis et définissent généralement un volume en tronc de pyramide inversé facilitant le démoulage. These ingot molds are molds with substantially prismatic sections, the faces of which are joined by slight roundings and generally define a volume in the form of an inverted pyramid trunk facilitating demolding.
Après chaque utilisation, la paroi interne de la lingotière doit être nettoyée afin d'obtenir une surface lisse dépourvue d' aspérités. After each use, the internal wall of the mold should be cleaned in order to obtain a smooth surface devoid of any roughness.
L'état de surface de ces lingotières est primordial pour le démoulage qui peut, éventuellement, être aidé en enduisant la face interne de la lingotière d'une couche d'huile ou de graphite. The surface condition of these molds is essential for demolding which can, if necessary, be helped by coating the internal face of the mold with a layer of oil or graphite.
En effet, si l'état de surface est mauvais, il y a un risque important que le lingot ne se démoule pas. Indeed, if the surface condition is bad, there is a significant risk that the ingot does not unmold.
Pour nettoyer ces lingotières, on couche la lingotière au moins indirectement sur un plan d'appui tel le sol et, à l'aide d'un dispositif de nettoyage (US-A-3.603.038) comprenant un outil abrasif porté à l'extrémité d'un bras soutenu par un châssis, on nettoie par passes successives les faces de la lingotière. To clean these molds, the mold is coated at least indirectly on a support surface such as the ground and, using a cleaning device (US-A-3,603,038) comprising an abrasive tool carried to the end of an arm supported by a frame, the faces of the mold are cleaned by successive passes.
Dans ce dispositif, l'outil abrasif est un disque abrasif entraîné en rotation autour d'un axe parallèle à la surface qu'il nettoie et c'est donc la surface cylindrique de l'outil qui effectue le nettoyage. In this device, the abrasive tool is an abrasive disc driven in rotation about an axis parallel to the surface which it cleans and it is therefore the cylindrical surface of the tool which performs the cleaning.
L'extrémité opposée du bras porte alors un moyen moteur placé latéralement avec un arbre moteur sur lequel l'outil prend son mouvement. The opposite end of the arm then carries a motor means placed laterally with a motor shaft on which the tool takes its movement.
A cet effet, l'outil abrasif est un disque pincé entre deux flasques et calé en rotation sur un arbre d'entrainement relié en rotation à l'arbre moteur par une transmission. To this end, the abrasive tool is a disc pinched between two flanges and locked in rotation on a drive shaft connected in rotation to the motor shaft by a transmission.
Cette solution a pour inconvénient notamment de ne pas permettre de nettoyer parfaitement les angles de la lingotière du fait notamment de la présence des flasques maintenant le disque. This solution has the drawback in particular of not making it possible to perfectly clean the angles of the ingot mold due in particular to the presence of the flanges holding the disc.
Même si le bras est monté rotatif autour de son axe longitudinal, ce dispositif connu nécessite de faire tourner la lingotière d'un quart de tour pour traiter les quatre faces de celle-ci. Even if the arm is mounted to rotate about its longitudinal axis, this known device requires the ingot mold to be turned a quarter of a turn to treat the four faces of the latter.
Dans un autre domaine technique on connaît un autre dispositif (FR-A-2.641.224) dans lequel l'axe de rotation de l'outil abrasif est sensiblement parallèle à l'axe longitudinal du tube cylindrique dans lequel il évolue. In another technical field, another device is known (FR-A-2,641,224) in which the axis of rotation of the abrasive tool is substantially parallel to the longitudinal axis of the cylindrical tube in which it operates.
Cette disposition est intéressante dans le cas d'une surface courbe mais le rayon de courbure de cette surface courbe doit être supérieur au rayon de l'outil abrasif pour permettre son travail. This arrangement is advantageous in the case of a curved surface but the radius of curvature of this curved surface must be greater than the radius of the abrasive tool to allow its work.
Un tel dispositif ne pourrait convenir pour une lingotière qui comprend essentiellement des faces planes raccordées entre elles par des arrondis de rayons de courbures réduits. Such a device would not be suitable for an ingot mold which essentially comprises planar faces connected to one another by rounded radii with reduced radii of curvature.
Toujours dans le domaine de la rectification, on connaît (US-A-5.111.623) une machine destinée à se déplacer de manière autonome à l'intérieur d'un tube de grand diamètre. Still in the field of grinding, there is known (US-A-5,111,623) a machine intended to move autonomously inside a large diameter tube.
Le dispositif est guidé dans le tube par des moyens appropriés et porte une chape supportant un moteur entraînant quant à lui un outil abrasif guidé en rotation autour d'un axe coaxial au rayon du tube dans lequel la machine se déplace. The device is guided in the tube by appropriate means and carries a yoke supporting a motor, meanwhile driving an abrasive tool guided in rotation about an axis coaxial with the radius of the tube in which the machine is moving.
L'outil est d'encombrement plus faible que le moteur et se déplace à la manière d'un pendule. The tool takes up less space than the motor and moves like a pendulum.
Ce type de machine ne peut convenir au nettoyage des lingotières car elles n'ont pas de section circulaire. This type of machine is not suitable for cleaning ingot molds because they do not have a circular section.
Un des résultats que l'invention vise à obtenir est un dispositif de nettoyage des faces internes d'une lingotière qui permette d'effectuer à la fois le nettoyage des surfaces planes et un travail correct dans les parties arrondies. One of the results which the invention aims to obtain is a device for cleaning the internal faces of an ingot mold which makes it possible to carry out both cleaning of the flat surfaces and correct work in the rounded parts.
Est également un autre résultat de l'invention, un tel dispositif qui permette de traiter les quatre faces de la lingotière sans qu'il soit nécessaire de tourner la lingotière. Another result of the invention is also such a device which makes it possible to treat the four faces of the mold without the need to rotate the mold.
A cet effet, l'invention a pour objet un tel dispositif de nettoyage d'une lingotière notamment caractérisé en ce que l'outil abrasif est porté par une tête constituée dans une pièce distincte du bras auquel elle est reliée de manière amovible et le dispositif, d'une part, comprend des moyens de positionnement angulaire de cette tête autour de l'axe longitudinal du bras et, d'autre part, porte un outil abrasif dont le diamètre est au moins égal et de préférence supérieur à la dimension maximale de la tête mesurée dans un même plan et dont l'axe de rotation est sensiblement perpendiculaire à la face qu'il doit nettoyer. To this end, the subject of the invention is such a device for cleaning an ingot mold, in particular characterized in that the abrasive tool is carried by a head formed in a part separate from the arm to which it is removably connected and the device , on the one hand, comprises means for angular positioning of this head around the longitudinal axis of the arm and, on the other hand, carries an abrasive tool whose diameter is at least equal and preferably greater than the maximum dimension of the head measured in the same plane and whose axis of rotation is substantially perpendicular to the face which it must clean.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement
- figure 1 : vue d'un dispositif de nettoyage,
- figure 2 : vue de l'extrémité du dispositif de nettoyage,
- figure 3 : vue en coupe d'un détail du dispositif.The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents
- Figure 1: view of a cleaning device,
- Figure 2: view of the end of the cleaning device,
- Figure 3: sectional view of a detail of the device.
En se reportant au dessin on voit que la lingotière 1 utilisée pour recevoir un métal ou alliage en fusion est couchée sur l'une de ses faces en vue d'être nettoyée par un dispositif 2 de nettoyage. Referring to the drawing, it can be seen that the mold 1 used to receive a molten metal or alloy is coated on one of its faces with a view to being cleaned by a cleaning device 2.
Ce dispositif 2 de nettoyage comprend un châssis 3 qui, placé à l'extérieur de la lingotière, présente un bras 4 à l'une des extrémités duquel un outil abrasif 5 tel une meule 5 est guidé et entrainé en rotation autour d'un axe de rotation 6. This cleaning device 2 comprises a frame 3 which, placed outside the ingot mold, has an arm 4 at one end of which an abrasive tool 5 such as a grinding wheel 5 is guided and rotated about an axis rotation 6.
Ce châssis 3 présente des moyens 7 en vue de le déplacer notamment le long de l'axe longitudinal 8 de la lingotière tels des roues et une poignée de manoeuvre. This chassis 3 has means 7 for moving it in particular along the longitudinal axis 8 of the mold, such as wheels and an operating handle.
Le dispositif 2 de nettoyage présente en outre à l'extrémité opposée du bras un moyen moteur 9 porté par le châssis et une transmission 10 qui reporte le mouvement engendré par le moteur à l'extrémité du bras 4 pour entraîner en rotation l'outil 5. The cleaning device 2 also has at the opposite end of the arm a motor means 9 carried by the chassis and a transmission 10 which transfers the movement generated by the motor to the end of the arm 4 to rotate the tool 5 .
Selon l'invention, l'outil 5 abrasif est porté par une tête 11 constituée dans une pièce distincte du bras 4 auquel elle est reliée de manière amovible et le dispositif, d'une part, comprend des moyens 12 de positionnement angulaire de cette tête autour de l'axe longitudinal 38 du bras 4 et, d'autre part, porte un outil abrasif 5 dont le diamètre D est au moins égal et de préférence supérieur à la dimension d maximale de la tête 11 mesurée dans un même plan et dont l'axe 6 de rotation est sensiblement perpendiculaire à la face la, lb, lc, id qu'il doit nettoyer. According to the invention, the abrasive tool 5 is carried by a head 11 formed in a separate part from the arm 4 to which it is removably connected and the device, on the one hand, comprises means 12 for angular positioning of this head around the longitudinal axis 38 of the arm 4 and, on the other hand, carries an abrasive tool 5 whose diameter D is at least equal and preferably greater than the maximum dimension d of the head 11 measured in the same plane and whose the axis of rotation 6 is substantially perpendicular to the face la, lb, lc, id which it must clean.
Avantageusement, tout en restant de préférence dans un plan radial à l'axe du bras, l'axe 6 de rotation de l'outil 5 abrasif est légèrement incliné par rapport à la verticale de la surface qu'il nettoie. Advantageously, while preferably remaining in a plane radial to the axis of the arm, the axis 6 of rotation of the abrasive tool 5 is slightly inclined relative to the vertical of the surface which it cleans.
C'est l'arête de l'outil abrasif qui permet de nettoyer correctement les arrondis formés entre deux faces successives. It is the edge of the abrasive tool which allows the rounded edges formed between two successive faces to be properly cleaned.
Les moyens 12 de positionnement comprennent des moyens 13a, 13b complémentaires de guidage en rotation de la tête par rapport au bras, tels deux portées cylindriques complémentaires et des moyens 14 de verrouillage en rotation de la tête par rapport au bras. The positioning means 12 comprise complementary means 13a, 13b for guiding the head in rotation relative to the arm, such as two complementary cylindrical bearing surfaces and means 14 for locking the head in rotation relative to the arm.
Avantageusement, les moyens 14 de verrouillage en rotation comprennent d'une part, deux brides 15, 16 portées pour l'une 15 par le bras et pour l'autre 16 par la tête et d'autre part, des moyens 17 d'application des brides l'une contre l'autre. Advantageously, the means 14 for locking in rotation comprise on the one hand, two flanges 15, 16 carried for one 15 by the arm and for the other 16 by the head and on the other hand, means 17 for application flanges against each other.
Avantageusement, l'une des brides présente dans sa face venant en vis à vis de l'autre bride une rainure 18 en T apte à loger la tête d'une vis (non représentée) et l'autre bride comprend au moins un perçage 19 pour l'engagement de la tige de la vis précitée. Advantageously, one of the flanges has in its face coming opposite the other flange a T-shaped groove 18 capable of accommodating the head of a screw (not shown) and the other flange comprises at least one bore 19 for the engagement of the rod of the aforementioned screw.
Dans une forme de réalisation, la transmission s'opère par pignon et la tête supportant l'outil abrasif loge un renvoi d'angle 20 comprenant lui même un moyen 21 de couplage avec l'extrémité d'un arbre 22 de transmission placé à l'intérieur du bras. In one embodiment, the transmission operates by pinion and the head supporting the abrasive tool houses a bevel gear 20 itself comprising a means 21 for coupling with the end of a transmission shaft 22 placed at the inside the arm.
Bien évidemment, cet arbre de transmission comprend des moyens de guidage en rotation, tels des roulements. Obviously, this drive shaft comprises means for guiding in rotation, such as bearings.
On peut bien entendu concevoir que la tête loge un moteur hydraulique. It is of course conceivable that the head houses a hydraulic motor.
Cette possibilité d'orientation de la tête permet de traiter les quatres surfaces de la lingotière sans que cela nécessite de tourner la lingotière d'un quart de tour à chaque fois. This possibility of orientation of the head makes it possible to treat the four surfaces of the ingot mold without requiring the rotation of the ingot mold by a quarter of a turn each time.
Egalement, le réglage de l'inclinaison de l'axe de rotation de la tête permet de régler l'angle d'attaque de la meule sur la surface. Also, adjusting the inclination of the axis of rotation of the head makes it possible to adjust the angle of attack of the grinding wheel on the surface.
De préférence, le chassis est supporté par un seul essieu et l'ensemble des moyens constituant le dispositif sont répartis de chaque coté de l'essieu afin d'équilibrer le dispositif car il ne faut oublier que la longueur du bras est de l'ordre de quatre mètres. Preferably, the chassis is supported by a single axle and all the means constituting the device are distributed on each side of the axle in order to balance the device because it should not be forgotten that the length of the arm is of the order four meters.
De préférence, le dispositif comprend des moyens 23, 24 pour amortir les chocs de la meule sur la surface à nettoyer. Preferably, the device comprises means 23, 24 for absorbing the impacts of the grinding wheel on the surface to be cleaned.
Ces moyens peuvent être obtenus par la flexibilité 23 du bras ou encore par un système 24 d'amortissement du renvoi d'angle dans la tête. These means can be obtained by the flexibility 23 of the arm or also by a system 24 for damping the bevel gear in the head.
