Abstract

The anvil is in the shape of a prism with flat upper and lower surfaces (22,24), a curved surface (16) forming part of a circle, two lateral surfaces (18,20) which come to a point, and two other lateral surfaces (26,28) adjacent to the curved surface. The two lateral surfaces adjacent to the curved surface are inclined at an angle between 3 degrees and 15 degrees to the median plane of the anvil and converge towards the upper or lower flat surface. One end of the anvil has projecting studs (26) to engage with holes in a ring, and the anvils are fitted into the ring with their inclined surfaces facing alternately in opposite directions.

Description

La présente invention concerne une enclume pour concasseur à impact centrifuge ayant globalement la forme d'un prisme comprenant deux bases et des surfaces latérales dont une surface latérale est une surface cylindrique avec un rayon de courbure déterminé et dont deux autres surfaces latérales ont des flancs respectivement adjacents à la surface cylindrique, ces flancs étant orientés vers l'axe de ladite surface cylindrique. L'invention concerne également un cercle d'enclumes pour concasseur à impact centrifuge comprenant un anneau porte-enclumes cylindrique avec une bride radiale intérieure et inférieure pour supporter verticalement une garniture d'enclumes du genre précité qui sont calées à l'intérieur de l'anneau porte-enclumes par effet de voûte.The present invention relates to an anvil for a centrifugal impact crusher having the overall shape of a prism comprising two bases and lateral surfaces, one lateral surface of which is a cylindrical surface with a determined radius of curvature and two other lateral surfaces of which have flanks respectively. adjacent to the cylindrical surface, these flanks being oriented towards the axis of said cylindrical surface. The invention also relates to an anvil circle for a centrifugal impact crusher comprising a cylindrical anvil ring with an inner and lower radial flange for vertically supporting a lining of anvils of the aforementioned kind which are wedged inside the anvil ring by arching effect.

Un concasseur avec un cercle d'enclumes de ce genre est décrit dans le document US 5,184,784. Dans ce concasseur, les enclumes sont librement posées à l'intérieur de l'anneau porte-enclumes et y sont retenues par effet de voûte sans aucune fixation particulière. Contrairement à d'autres systèmes connus prévoyant des moyens de fixation qui subissent les impacts intenses et sont de ce fait sujet à une usure rapide, le maintien des enclumes par effet de voûte permet une meilleure répartition des chocs et sollicitations sur l'anneau d'enclumes et une plus longue durée de l'ensemble. Par ailleurs, en l'absence de toute fixation interne, on peut user les enclumes jusqu'à la tôle de l'anneau.A crusher with such an anvil circle is described in US 5,184,784. In this crusher, the anvils are freely placed inside the anvil ring and are retained there by vault effect without any particular fixing. Unlike other known systems providing fastening means which undergo intense impacts and are therefore subject to rapid wear, the maintenance of the anvils by arching effect allows a better distribution of the shocks and stresses on the ring. anvils and a longer duration of the whole. Furthermore, in the absence of any internal fixing, the anvils can be worn down to the sheet of the ring.

Ce système de montage des enclumes présente toutefois l'inconvénient que les enclumes neuves sont difficiles à mettre en place, car en alignant les enclumes individuelles l'une après l'autre, il est souvent difficile d'introduire la dernière enclume dans l'espace restant. Plus difficile encore est le remplacement des enclumes usées à cause du fait qu'elles sont souillées par de la matière broyée.However, this anvil mounting system has the disadvantage that new anvils are difficult to install, since by aligning the individual anvils one after the other, it is often difficult to insert the last anvil into the remaining space. Even more difficult is the replacement of worn anvils because of the fact that they are soiled with crushed material.

Par ailleurs, le remplacement d'enclumes individuelles dans le concasseur n'est pas possible sans démontage du cercle d'enclumes car, en l'absence de toute fixation, le dégagement d'une enclume provoquerait l'effondrement des autres enclumes.Furthermore, the replacement of individual anvils in the crusher is not possible without dismantling the anvil ring because, in the absence of any fixing, the release of an anvil would cause the other anvils to collapse.

Le but de la présente invention est de prévoir une nouvelle enclume ainsi qu'un cercle d'enclumes équipé de telles enclumes également fixées par effet de voûte mais qui permettent de faciliter la mise en place et le remplacement des enclumes individuellement.The object of the present invention is to provide a new anvil as well as an anvil circle equipped with such anvils also fixed by vault effect but which make it easier to install and replace the anvils individually.

Pour atteindre cet objectif, la présente invention prévoit une enclume du genre décrit dans le préambule qui est essentiellement caractérisée en ce que les deux flancs adjacents à la surface cylindrique sont inclinés par rapport à un plan médian de l'enclume passant par l'axe de courbure de la surface cylindrique, les inclinaisons des deux flancs étant identiques et de sens opposés.To achieve this objective, the present invention provides an anvil of the kind described in the preamble which is essentially characterized in that the two flanks adjacent to the cylindrical surface are inclined relative to a median plane of the anvil passing through the axis of curvature of the cylindrical surface, the inclinations of the two sides being identical and in opposite directions.

L'inclinaison de ces flancs est de préférence de l'ordre de 3°-15°.The inclination of these sides is preferably of the order of 3 ° -15 °.

L'une des bases de l'enclume, de préférence celle vers laquelle divergent lesdits flancs comporte deux tenons saillants.One of the bases of the anvil, preferably the one towards which the said sides diverge has two protruding studs.

L'invention prévoit également un cercle d'enclumes équipé d'un nombre pair d'enclumes qui sont orientées, verticalement, alternativement dans un sens et dans l'autre.The invention also provides an anvil circle equipped with an even number of anvils which are oriented, vertically, alternately in one direction and in the other.

La bride intérieure de l'anneau porte-enclumes comporte des ouvertures servant de logement aux tenons des enclumes qui sont orientées avec les tenons vers le bas.The inner flange of the anvil ring has openings for housing the studs of the anvils which are oriented with the studs down.

La mise en place des enclumes neuves consiste simplement à placer d'abord la moitié des enclumes avec les tenons orientés vers le bas et ancrer ceux-ci dans les ouvertures prévues à cet effet dans la bride de l'anneau porte-enclumes et à glisser ensuite dans les espaces restant entre ces enclumes placées celles qui sont orientées avec les tenons vers le haut ou celles qui ne comportent pas de tenons. La mise en place de ces dernières enclumes est facilitée par l'inclinaison des flancs latéraux qui guident automatiquement les enclumes sur leur siège.The installation of new anvils consists simply in placing first half of the anvils with the pins facing down and anchor them in the openings provided for this purpose in the flange of the anvil ring and then slide into the spaces remaining between these anvils placed those oriented with the pins up or those that do not have studs. The installation of these latter anvils is facilitated by the inclination of the lateral flanks which automatically guide the anvils on their seats.

La Figure 1 montre un cercle d'enclumes analogue à celui décrit dans le document US 5,184,784 mais équipé, dans l'exemple représenté, de 18 enclumes individuelles 10 selon la présente invention. Ces enclumes garnissent la surface intérieure d'un anneau porte-enclumes circulaire 12 représenté sur la Figure 2. Cet anneau 12 comporte, à sa base, une bride radiale intérieure 14 destinée à supporter la garniture d'enclumes 10.FIG. 1 shows an anvil circle similar to that described in document US 5,184,784 but equipped, in the example shown, of 18 individual anvils 10 according to the present invention. These anvils line the interior surface with a circular anvil ring 12 shown in FIG. 2. This ring 12 has, at its base, an internal radial flange 14 intended to support the anvil lining 10.

Une enclume 10 selon la présente invention est représentée sur les Figures 3 à 5. Une telle enclume 10, coulée en un alliage ayant une bonne résistance aux chocs, possède globalement la forme d'un prisme, de préférence à section triangulaire unique avec une face cylindrique arrière 16 destinée à épouser la courbure de l'anneau 12, deux faces latérales 18 et 20 et deux bases 22 et 24.An anvil 10 according to the present invention is shown in Figures 3 to 5. Such an anvil 10, cast in an alloy having good impact resistance, generally has the shape of a prism, preferably of single triangular section with one face. rear cylindrical 16 intended to match the curvature of the ring 12, two lateral faces 18 and 20 and two bases 22 and 24.

Selon la caractéristique essentielle de la présente invention, les deux surfaces latérales 18 et 20 comportent, à leur jonction avec la surface cylindrique arrière 16, deux flancs 26 et 28 qui forment des dépouilles avec une inclinaison pouvant varier entre 3° et 15° par rapport à la verticale, conférant ainsi à l'enclume 10 une forme légèrement tronconique comme le montre la Figure 5. Les surfaces latérales 18, 20 elles-mêmes peuvent être verticales ou être également légèrement inclinées comme leurs flancs 26 et 28. Le plan des flancs 26 et 28 est, en outre, globalement perpendiculaire à la face cylindrique 16, c'est-à-dire orienté vers l'axe de courbure de cette surface 16 afin d'assurer le maintien des enclumes 10 par effet de voûte comme dans le brevet précité.According to the essential characteristic of the present invention, the two lateral surfaces 18 and 20 comprise, at their junction with the rear cylindrical surface 16, two sides 26 and 28 which form undercuts with an inclination which can vary between 3 ° and 15 ° relative to vertically, thus giving the anvil 10 a slightly frustoconical shape as shown in Figure 5. The side surfaces 18, 20 themselves can be vertical or also be slightly inclined like their sides 26 and 28. The plane of the sides 26 and 28 is, moreover, generally perpendicular to the cylindrical face 16, that is to say oriented towards the axis of curvature of this surface 16 in order to ensure the maintenance of the anvils 10 by arch effect as in the aforementioned patent.

La base la plus large de l'enclume, c'est-à-dire celle vers laquelle divergent les flancs 26 et 28, comporte deux tenons 30, tandis que la bride 14 de l'anneau porte-enclumes comporte des ouvertures 32 formant des logements pour ces tenons 30.The widest base of the anvil, that is to say the one towards which the sides 26 and 28 diverge, has two studs 30, while the flange 14 of the anvil ring has openings 32 forming housing for these tenons 30.

La Figure 6 illustre schématiquement la mise en place des enclumes dans l'anneau porte-enclumes 12 pour réaliser le cercle d'enclumes représenté sur la Figure 1. On positionne d'abord neuf enclumes 10, tenons 30 orientés vers le bas en veillant à ce que ces tenons 30 soient engagés dans les ouvertures correspondantes 32 de la bride 14 de l'anneau 12. Les neuf enclumes restantes 10a sont ensuite glissées, avec les tenons 30 orientés vers le haut, dans les espaces restant entre les enclumes 10 précédemment mises en place. A cause des dépouilles des flancs latéraux 26 et 28, les enclumes 10a et leurs logements entre les enclumes 10 déjà placées ont des conicités complémentaires, de sorte que la mise en place des enclumes est extrêmement facile vu qu'ils sont guidés automatiquement en place. Une fois toutes les enclumes 10 et 10a ainsi positionnées, elles sont maintenues radialement par effet de voûte étant donné que leurs flancs 26 et 28, outre leurs dépouilles, convergent en direction de l'axe de l'anneau 12.Figure 6 schematically illustrates the placement of the anvils in the anvil ring 12 for realize the circle of anvils shown in Figure 1. First place nine anvils 10, pins 30 oriented downward ensuring that these pins 30 are engaged in the corresponding openings 32 of the flange 14 of the ring 12. The nine remaining anvils 10a are then slid, with the pins 30 facing upwards, into the spaces remaining between the anvils 10 previously placed. Because of the sides of the lateral flanks 26 and 28, the anvils 10a and their housings between the anvils 10 already placed have complementary conicities, so that the installation of the anvils is extremely easy since they are automatically guided in place. Once all the anvils 10 and 10a have been positioned in this way, they are held radially by vault effect since their sides 26 and 28, in addition to their bodies, converge towards the axis of the ring 12.

Le remplacement d'enclumes individuelles est aussi facile que leur mise en place. Les enclumes 10a orientées avec les tenons 30 vers le haut peuvent être soulevées individuellement hors de leurs logements, les autres enclumes 10 et 10a restant en place vu qu'elles sont coincées radialement par effet de voûte et qu'elles ne peuvent pas bouger latéralement à cause des enclumes qui sont coincées par leurs tenons 30 dans les logements 32 de l'anneau 12. Ceci permet le remplacement d'enclumes individuelles dans le concasseur sans nécessiter de démonter le cercle d'enclumes.Replacing individual anvils is as easy as setting them up. The anvils 10a oriented with the pins 30 upwards can be lifted individually out of their housings, the other anvils 10 and 10a remaining in place since they are wedged radially by arching effect and they cannot move laterally at because of the anvils which are trapped by their tenons 30 in the housings 32 of the ring 12. This allows the replacement of individual anvils in the crusher without the need to disassemble the anvil ring.

Les enclumes 10 qui sont ancrées par leurs tenons 30 dans la bride 14 peuvent également être démontées individuellement mais, à cause des dépouilles des flancs 26 et 28, il faut d'abord dégager les deux enclumes voisines 10a.The anvils 10 which are anchored by their tenons 30 in the flange 14 can also be dismantled individually but, because of the remains of the sides 26 and 28, it is first necessary to clear the two adjacent anvils 10a.

Pour faciliter la manipulation des enclumes, notamment le montage et le démontage avec un outil approprié, chaque enclume peut être équipée d'un moyen de saisie appropriée, symbolisée, dans l'exemple représenté, par un alésage 34 traversant verticalement chaque enclume.To facilitate the handling of the anvils, in particular assembly and disassembly with an appropriate tool, each anvil can be equipped with an appropriate gripping means, symbolized, in the example shown, by a bore 34 passing vertically through each anvil.

Les fonctions des tenons dans les enclumes et des logements peuvent également être inversées dans la mesure où les logements 32 de l'anneau 12 peuvent être remplacés par des tenons et que les tenons 30 des enclumes peuvent être remplacés par des cavités pour recevoir les tenons de l'anneau.The functions of the tenons in the anvils and of the housings can also be reversed insofar as the housings 32 of the ring 12 can be replaced by tenons and the tenons 30 of the anvils can be replaced by cavities to receive the tenons of the ring.

Les Figures 7 et 8 représentent les deux enclumes d'un mode de réalisation qui prévoit deux types différents d'enclumes telles que réunies dans le cercle d'enclumes représenté sur la Figure 9. Les enclumes 40 de la Figure 7 sont des enclumes proprement dites et correspondent aux enclumes 10 des figures précédentes. Ces enclumes 40 ont également une face cylindrique arrière 42 et deux flancs 44 et 46 orientés sur l'axe de courbure de la face 42 pour être calés par effet de voûte et inclinés de 3° à 15° par rapport à la verticale. Toutefois, contrairement aux enclumes 10, les enclumes 40 sont dépourvues de tenons.Figures 7 and 8 show the two anvils of an embodiment which provides for two different types of anvils as joined in the anvil circle shown in Figure 9. The anvils 40 of Figure 7 are anvils themselves and correspond to the anvils 10 of the previous figures. These anvils 40 also have a rear cylindrical face 42 and two sides 44 and 46 oriented on the axis of curvature of the face 42 to be wedged by arch effect and inclined by 3 ° to 15 ° relative to the vertical. However, unlike anvils 10, anvils 40 are devoid of studs.

Les enclumes 50 de la Figure 8 sont en fait des mini-enclumes qui, bien que recevant également de la matière à concasser, font plutôt office d'intercalaires servant à caler les enclumes 40 proprement dites. Les enclumes 50 comportent également une face cylindrique arrière 52 et des flancs latéraux 54 et 56 orientés sur l'axe de courbure de la face arrière et une dépouille par rapport à la verticale identique à celle des enclumes 40 mais de sens contraires. Les enclumes 50 comportent également chacune un tenon 58 sur la base vers laquelle divergent les flancs 54, 56, sur la Figure 8, la base inférieure.The anvils 50 of Figure 8 are in fact mini-anvils which, although also receiving material to be crushed, rather serve as spacers used to wedge the anvils 40 proper. The anvils 50 also have a rear cylindrical face 52 and lateral flanks 54 and 56 oriented on the axis of curvature of the rear face and a clearance relative to the vertical identical to that of the anvils 40 but in opposite directions. The anvils 50 also each have a stud 58 on the base towards which the sides 54, 56 diverge, in FIG. 8, the lower base.

La mise en place des enclumes 40 et 50 est analogue à celle du mode de réalisation précédent sachant que chaque enclume 40 doit être entourée de deux enclumes 50 et vice versa. On place d'abord les enclumes 50 en veillant à ce que leur tenon 50 soit ancré dans les logements correspondants de l'anneau. Il suffit ensuite de glisser les enclumes 40 entre les enclumes 50 préalablement posées, les inclinaisons de leurs flancs 44 et 46 et celles des flancs 54 et 56 des enclumes 50 les guidant automatiquement dans la position correcte.The placement of the anvils 40 and 50 is analogous to that of the previous embodiment, knowing that each anvil 40 must be surrounded by two anvils 50 and vice versa. The anvils 50 are first placed while ensuring that their tenon 50 is anchored in the corresponding housings of the ring. It then suffices to slide the anvils 40 between the anvils 50 previously laid, the inclinations of their sides 44 and 46 and those of the sides 54 and 56 of the anvils 50 automatically guiding them into the correct position.

Le mode de réalisation de la Figure 9 est essentiellement destiné à remplacer celui des Figures précédentes afin de réduire le nombre d'enclumes lorsque la nature de la matière à concasser le demande.The embodiment of FIG. 9 is essentially intended to replace that of the preceding Figures in order to reduce the number of anvils when the nature of the material to be crushed demands it.
