Definitions
- Sharp tool blades require regular maintenance to maintain their cutting power. This maintenance consists of regular sharpening operations during which the cutting edge is reformed using a grinding wheel or a suitable machine; between two sharpening operations, the wear of the cutting edge is delayed by sharpening operations by means of a tool called a “gun”, by means of a diabolo sharpener, or even by means of a module sharpening with crossed pins (fixed or articulated).
- sharpening steel used depends on the degree of wear of the blade. Very often the operator uses a "rough” rifle to rough the work, before using a “smooth” finishing rifle serving as a burnisher for the edge of the blade. But the implementation of these sharpening rifles requires significant technicality and an experienced helping hand; therefore they cannot be used effectively by just anyone.
- Diabolo type and fixed pin type sharpeners are relatively ineffective and do not provide a sharpening quality interesting.
- Articulated crossed pin type sharpening modules are generally used for browning tool blades and have the advantage of being able to be used satisfactorily even by people who do not have a great deal of experience or great technical skill. in the field of sharpening.
- An apparatus of this kind described in document US Pat. No. 5,478,272, consists of a flat base in which is arranged a vertical slot intended for the passage of the sharpening blade, and provided with two sharpening pins which intersect opposite said slot.
- the two sharpening pins made of steel wire, have a generally curved shape and they are articulated at their upper end on the flat base, by means of rotary knobs associated with return springs.
- the present invention provides a sharpening device of the kind of that which has just been described, that is to say of the type with hinged crossed pins, but simplified structure, therefore easier to maintain and less cost expensive.
- Another object of the present invention is to improve the guidance of the tool blade to perfect the quality of sharpening.
- Yet another object of the invention is to propose, in addition to the two articulated sharpening pins used as a burnisher, a device complementary capable of ensuring more advanced straightening operations tool blade wire (more advanced operations akin to those filled with conventional "rough" rifles).
- the apparatus according to the present invention for sharpening the blades of sharp tools, is therefore of the type comprising a plate provided with an opening allowing the passage of the tool blade, opposite which opening are arranged two structures of sharpening in the form of elongated intersecting pins, which sharpening pins are articulated at one of their ends on said plate, each on one side of said opening, and comprise elastic return means, so to obtain a mobile sharpening V under the pressure of the blade to be sharpened.
- each sharpening spindle consists of a U-shaped rod comprising two parallel or substantially parallel arms connected at one of their ends and the two free ends of which have square returns , forming articulation axes which are housed free to rotate in offset offset orifices, arranged on said plate or on a suitable support integral with said plate, so as to obtain an elastic return of said sharpening pins by a twist effect.
- the two sharpening pins have a shape general curve permanently forming an angle of about 40 ° between them.
- the plate of the device is provided with a vertical opening, the two sharpening pins being articulated in the part top of the support plate, on axes perpendicular to the plane of this last.
- the two sharpening pins each have square returns oriented in opposite directions. Resting, these returns are advantageously offset.
- the returns to the square of the sharpening pins, which form the axes of articulation, can be easily extracted from their receiving orifices, so as to make said pins removable with a view in particular to facilitating their replacement or cleaning.
- the two sharpening pins are nested one inside the other.
- the sharpening device comprises a structure for guiding the tool blade, in the form of two independent flat blades arranged opposite, fixed at their end upper on the plate or on a support integral with said plate. These two blades are spaced from each other in the upper part and they come into contact with each other at their lower end to define a self-tightening guide V, placed just behind the two sharpening pins. .
- These two guide blades are preferably dihedral to form a first V-shaped flare in the upper part of the opening of the plate, and a second tight V-shaped in its lower part.
- the guide blades are provided, in the lower part, with means for straightening the wire of the tool blades.
- These means are advantageously in the form of two tabs monobloc each taken from one of the guide blades and folded in opposite direction to each other to form a straightening Vee.
- the plate of the sharpening device comprises a monobloc tab allowing its removable embedding in a support appropriate.
- the sharpening device illustrated in Figures 1 to 5 consists of a metal plate 1 in the middle zone of which is fitted a opening 2 which opens upwards.
- the plate 1 is equipped of two added structures 3 and 4 constituting supports, on the one hand for a pair of flat blades 6, 8 intended to guide the blade of the tool which is wishes to sharpen, and on the other hand for two sharpening pins 10, 12 which cross just in front of said guide blades 6, 8.
- the support 3 is illustrated in isolation in Figures 6 to 8, and the support 4 in Figures 9 to 11; these supports 3 and 4 both have the same general structure, but the support 3 is slightly shorter, so as to allow the nesting of the two sharpening pins 10, 12, as will be seen below.
- Each support 3, 4 is generally U-shaped comprising a base 14, a rear wing 16 and a front wing 18. They extend perpendicular to the plane of the plate 1, projecting forward, fixed by welding their rear wing 16 on said plate 1 along the edges of the opening 2.
- a notch 20 arranged in the rear wing 16, which facilitates the correct positioning of the supports 3 and 4 on a complementary form of recess cut in the plate 1, before the connection by welding.
- the base 14 of the supports 3 and 4 has a threaded orifice 22 which allows the removable fixing of the flat blades 6 and 8 by means of a screw 24, 26 (FIG. 4).
- the two flat blades 6 and 8 are made for example of chromed spring stainless steel; they are arranged opposite each other and they extend perpendicular to the plane of the plate 1. These blades 6, 8 each have an L-shaped end return 28 which allows them to be fixed to the supports 3 and 4 by means of the screws 24, 26; from this return at L 28, the two blades 6 and 8 each take the form of a dihedral to form together a first flared Vee 30 in the upper part of the opening 2, followed by a second tightened Vee 32, in the lower part of said opening.
- the lower edges 34 and 36 of the two blades 6 and 8 come into contact with each other to form a self-tightening guide system.
- the two blades 6 and 8 have offset internal cutouts 38 and 40 (Figure 2) which form one-piece tabs folded in opposite directions to each other to form a Vee 42 allowing the straightening of the wire from the tool blade, in perfect alignment.
- the angle formed between the two tongues 38 and 40 is of the order of 40 °.
- Each monobloc tongue 38, 40 is associated with a lateral opening allowing the embedding of the homologous tongue.
- the two sharpening pins 10 and 12 are made of metal wire, for example of chromed spring stainless steel wire. They consist of a U-shaped rod, comprising two parallel arms 48, 50, integral at one of their ends 52 and whose free ends include monobloc returns to the square 54, 56, illustrated in dotted lines on the FIG. 5, which comes to be fitted in suitable orifices 58, 60 arranged in the front wing 18 of the supports 3 and 4. This embedding of the returns 54 and 56 in the orifices 58 and 60 authorizes the articulation of the pins 10 and 12 on their respective support 3, 4, around axes perpendicular to the support plate 1.
- the orifices 58 and 60 extend perpendicular to the plane of the plate 1 and they pass right through the front wing 18 of the supports 3 and 4.
- the two orifices 58 and 60 are offset to obtain an elastic return system of the pins 10 and 12 by a twisting effect of the two parallel arms 48 and 50.
- the positioning of the returns 54, 56, and that of the two receiving orifices 58 , 60 is suitable for obtaining the desired elastic return characteristics.
- the two arms 48 and 50 of the pins 10 and 12 are parallel, and one of these arms is a little longer than the other to offset the two returns 54 and 56 in order to allow them to be embedded in the ports 58, 60.
- returns 54, 56 are oriented in opposite directions from each other so that the two parallel arms 48, 50 of the pins 10, 12 are positioned on either side of the front wings 18 of the supports 3 and 4, this positioning being possible thanks to the elasticity of the end link 52 of said pins.
- the returns 54 and 56 are simply fitted into the orifices 58 and 60, free to rotate and removable.
- the two sharpening pins 10 and 12 are mounted nested one in the other as illustrated in Figures 1, 3 and 5 to optimize the sharpening operations, and also to limit the size of the device. This nesting is achieved here thanks to a slight difference in length of supports 3 and 4.
- stop structures 62 arranged on the sides of the plate 1.
- These stops 62 can be made in one piece, by folding of the lateral parts of the plate 1; they can also be made up independent elements, reported and fixed by any appropriate means.
- a small cutout 64 ( Figures 1 and 4) structured to form a control gauge allowing the operator to check the wear of the tip of his knife.
- the support plate 1 has a generally triangular shape; it may include internal openings 66 on either side of the through opening 2, which make it possible to lighten its weight.
- the plate 1 is provided with a monobloc tab 68 which allows the removable embedding of the sharpening device in an appropriate support, fixed on the work station. The device can thus very easily be removed from its support, in particular for cleaning or disinfection.
- An internal cutout 70 arranged in the one-piece tab 68 further makes it possible to lighten the weight of the device.
- the two sharpening pins 10 and 12 are then used to finish the sharpening operation, that is to say to “brown” or smooth the tool blade, as can be done so classic with a "smooth” rifle.
- the operator then makes back and forth movements of the tool blade on the two sharpening pins 10, 12, exerting a pressure just sufficient not to reach the straightening V 42.
- the two sharpening pins 10 and 12 are similar to movable torsion bars in the form of arcs and they make it possible to keep between them, and whatever the penetration depth of the tool blade in the tight Vee 32 , the right angle of attack to optimize the work on the edge of the blade.
- the two sharpening pins 10 and 12 intrinsically have their own elastic return means, which simplifies the structure of the device. In addition, these two pins can very easily be removed and support lifts, especially for replacement operations following deterioration, or simply for cleaning.
- the apparatus according to the present invention has a general structure relatively simple and very complete since it offers two sets associated which allow to work differently the wire of the blades of tools.

Abstract
Description
La présente invention concerne un outillage pour affiler les lames d'outils tranchants ou coupants, et en particulier les lames de couteaux.The present invention relates to a tool for sharpening tool blades sharp or sharp, and in particular knife blades.
Les lames d'outils tranchants nécessitent un entretien régulier pour
conserver leur pouvoir de coupe.
Cet entretien consiste en des opérations régulières d'affûtage au cours
desquelles on reforme le taillant au moyen d'une meule ou d'une machine
adaptée ; entre deux opérations d'affûtage, l'usure du taillant est retardée par
des opérations d'affilage au moyen d'un outil appelé « fusil », au moyen d'un
affileur à diabolo, ou encore au moyen d'un module d'affilage à broches
croisées (fixes ou articulées).Sharp tool blades require regular maintenance to maintain their cutting power.
This maintenance consists of regular sharpening operations during which the cutting edge is reformed using a grinding wheel or a suitable machine; between two sharpening operations, the wear of the cutting edge is delayed by sharpening operations by means of a tool called a “gun”, by means of a diabolo sharpener, or even by means of a module sharpening with crossed pins (fixed or articulated).
Le type de fusil d'affilage utilisé est fonction du degré d'usure de la lame.
Bien souvent l'opérateur se sert d'un fusil « rugueux » pour dégrossir le travail,
avant d'utiliser un fusil de finition « lisse » servant de brunissoir pour le fil de la
lame.
Mais la mise en oeuvre de ces fusils d'affilage nécessite une technicité
importante et un coup de main expérimenté ; en conséquence ils ne peuvent
pas être utilisés efficacement par n'importe qui.The type of sharpening steel used depends on the degree of wear of the blade. Very often the operator uses a "rough" rifle to rough the work, before using a "smooth" finishing rifle serving as a burnisher for the edge of the blade.
But the implementation of these sharpening rifles requires significant technicality and an experienced helping hand; therefore they cannot be used effectively by just anyone.
Les affileurs du type à diabolo et ceux du type à broches fixes sont relativement inefficaces et ne permettent pas d'obtenir une qualité d'affilage intéressante.Diabolo type and fixed pin type sharpeners are relatively ineffective and do not provide a sharpening quality interesting.
Les modules d'affilage du type à broches croisées articulées servent
généralement à brunir les lames d'outils et présentent l'intérêt de pouvoir être
utilisés de manière satisfaisante même par des personnes ne disposant pas
d'une grande expérience ou d'une grande technicité dans le domaine de
l'aiguisage.
Un appareil de ce genre, décrit dans le document US-A-5 478 272, est
constitué d'une base plane dans laquelle est aménagée une fente verticale
destinée au passage de la lame à aiguiser, et munie de deux broches d'affilage
qui se croisent en regard de ladite fente. Les deux broches d'affilage, réalisées
en fil d'acier, ont une forme générale courbe et elles sont articulées au niveau
de leur extrémité supérieure sur la base plane, par l'intermédiaire de boutons
rotatifs associés à des ressorts de rappel. Ces broches forment entre elles un
Vé d'affilage qui est mobile sous la pression de la lame d'outil que l'on désire
aiguiser ; le Vé mobile correspondant permet d'assurer une pression de
traitement régulière ou relativement régulière sur la lame d'outil.
Des butoirs inférieurs et supérieurs limitent le pivotement desdites broches
entre une position haute et une position basse.Articulated crossed pin type sharpening modules are generally used for browning tool blades and have the advantage of being able to be used satisfactorily even by people who do not have a great deal of experience or great technical skill. in the field of sharpening.
An apparatus of this kind, described in document US Pat. No. 5,478,272, consists of a flat base in which is arranged a vertical slot intended for the passage of the sharpening blade, and provided with two sharpening pins which intersect opposite said slot. The two sharpening pins, made of steel wire, have a generally curved shape and they are articulated at their upper end on the flat base, by means of rotary knobs associated with return springs. These spindles form between them a sharpening V which is mobile under the pressure of the tool blade which it is desired to sharpen; the corresponding mobile V ensures a regular or relatively regular treatment pressure on the tool blade.
Lower and upper buffers limit the pivoting of said pins between a high position and a low position.
La structure de ce type d'appareil est cependant relativement complexe, en particulier du fait de la présence des ressorts de rappel intégrés dans les boutons rotatifs. En outre, ces ressorts fatiguent assez rapidement et il est nécessaire de les remplacer régulièrement, ce qui n'est pas toujours très facile à réaliser, et ce qui entraíne des coûts de pièces et de main d'oeuvre conséquents.The structure of this type of device is however relatively complex, in particular due to the presence of return springs integrated in the rotary knobs. In addition, these springs tire fairly quickly and it is necessary to replace them regularly, which is not always very easy to achieve, and what results in costs of parts and labor consistent.
La présente invention propose un appareil d'affilage du genre de celui qui vient d'être décrit, c'est-à-dire du type à broches croisées articulées, mais de structure simplifiée, donc d'entretien plus aisé et de coût de revient moins onéreux.The present invention provides a sharpening device of the kind of that which has just been described, that is to say of the type with hinged crossed pins, but simplified structure, therefore easier to maintain and less cost expensive.
Un autre objectif de la présente invention est d'améliorer le guidage de la lame d'outil pour parfaire la qualité d'affilage.Another object of the present invention is to improve the guidance of the tool blade to perfect the quality of sharpening.
Encore un autre but de l'invention est de proposer, en complément des deux broches d'affilage articulées servant de brunissoir, un dispositif complémentaire apte à assurer des opérations plus poussées de redressage du fil de la lame d'outil (opérations plus poussées qui s'apparentent à celles remplies par les fusils « rugueux » classiques).Yet another object of the invention is to propose, in addition to the two articulated sharpening pins used as a burnisher, a device complementary capable of ensuring more advanced straightening operations tool blade wire (more advanced operations akin to those filled with conventional "rough" rifles).
L'appareil conforme à la présente invention, pour affiler les lames d'outils
tranchants, est donc du type comprenant une platine munie d'une ouverture
permettant le passage de la lame d'outil, en regard de laquelle ouverture sont
aménagées deux structures d'affilage en forme de broches allongées qui se
croisent, lesquelles broches d'affilage sont articulées au niveau de l'une de
leurs extrémités sur ladite platine, chacune d'un côté de ladite ouverture, et
comportent des moyens de rappel élastiques, de manière à obtenir un Vé
d'affilage mobile sous la pression de la lame à affiler.
Conformément à la présente invention, chaque broche d'affilage est constituée
d'une tige conformée en U comprenant deux bras parallèles ou sensiblement
parallèles reliés au niveau de l'une de leurs extrémités et dont les deux
extrémités libres comportent des retours à l'équerre, formant des axes
d'articulation qui viennent se loger libres de rotation dans des orifices
d'encastrement désaxés, aménagés sur ladite platine ou sur un support
approprié solidaire de ladite platine, de manière à obtenir un rappel élastique
desdites broches d'affilage par un effet de torsion.The apparatus according to the present invention, for sharpening the blades of sharp tools, is therefore of the type comprising a plate provided with an opening allowing the passage of the tool blade, opposite which opening are arranged two structures of sharpening in the form of elongated intersecting pins, which sharpening pins are articulated at one of their ends on said plate, each on one side of said opening, and comprise elastic return means, so to obtain a mobile sharpening V under the pressure of the blade to be sharpened.
According to the present invention, each sharpening spindle consists of a U-shaped rod comprising two parallel or substantially parallel arms connected at one of their ends and the two free ends of which have square returns , forming articulation axes which are housed free to rotate in offset offset orifices, arranged on said plate or on a suitable support integral with said plate, so as to obtain an elastic return of said sharpening pins by a twist effect.
Toujours selon l'invention, les deux broches d'affilage ont une forme générale courbe faisant en permanence entre elles un angle de l'ordre de 40°.Still according to the invention, the two sharpening pins have a shape general curve permanently forming an angle of about 40 ° between them.
Toujours selon l'invention, la platine de l'appareil est munie d'une ouverture verticale, les deux broches d'affilage étant articulées dans la partie supérieure de la platine support, sur des axes perpendiculaires au plan de cette dernière.Still according to the invention, the plate of the device is provided with a vertical opening, the two sharpening pins being articulated in the part top of the support plate, on axes perpendicular to the plane of this last.
Selon une forme de réalisation préférée, les deux broches d'affilage comportent chacune des retours à l'équerre orientés en sens inverse. Au repos, ces retours sont avantageusement désaxés.According to a preferred embodiment, the two sharpening pins each have square returns oriented in opposite directions. Resting, these returns are advantageously offset.
Les retours à l'équerre des broches d'affilage, qui forment les axes d'articulation, peuvent être facilement extraits de leurs orifices de réception, de manière à rendre lesdites broches amovibles en vue notamment de faciliter leur remplacement ou leur nettoyage.The returns to the square of the sharpening pins, which form the axes of articulation, can be easily extracted from their receiving orifices, so as to make said pins removable with a view in particular to facilitating their replacement or cleaning.
Selon une autre particularité intéressante, les deux broches d'affilage sont imbriquées l'une dans l'autre.According to another interesting feature, the two sharpening pins are nested one inside the other.
Selon encore une autre particularité, l'appareil d'affilage conforme à la
présente invention comporte une structure de guidage de la lame d'outil, en
forme de deux lames plates indépendantes disposées en vis-à-vis, fixées au
niveau de leur extrémité supérieure sur la platine ou sur un support solidaire de
ladite platine. Ces deux lames sont écartées l'une de l'autre en partie
supérieure et elles viennent en contact l'une avec l'autre au niveau de leur
extrémité inférieure pour définir un Vé de guidage autoserrant, disposé juste
derrière les deux broches d'affilage.
Ces deux lames de guidage sont de préférence en dièdre pour former un
premier Vé évasé dans la partie supérieure de l'ouverture de la platine, et un
second Vé resserré, dans sa partie inférieure. According to yet another particularity, the sharpening device according to the present invention comprises a structure for guiding the tool blade, in the form of two independent flat blades arranged opposite, fixed at their end upper on the plate or on a support integral with said plate. These two blades are spaced from each other in the upper part and they come into contact with each other at their lower end to define a self-tightening guide V, placed just behind the two sharpening pins. .
These two guide blades are preferably dihedral to form a first V-shaped flare in the upper part of the opening of the plate, and a second tight V-shaped in its lower part.
Selon encore une autre caractéristique, les lames de guidage sont munies, en partie inférieure, de moyens pour redresser le fil des lames d'outils. Ces moyens se présentent avantageusement sous la forme de deux languettes monobloc prélevées chacune dans l'une des lames de guidage et pliées en sens inverse l'une de l'autre pour former un Vé de redressage.According to yet another characteristic, the guide blades are provided, in the lower part, with means for straightening the wire of the tool blades. These means are advantageously in the form of two tabs monobloc each taken from one of the guide blades and folded in opposite direction to each other to form a straightening Vee.
Selon une autre particularité, la platine de l'appareil d'affilage comporte une patte monobloc permettant son encastrement amovible dans un support approprié.According to another particular feature, the plate of the sharpening device comprises a monobloc tab allowing its removable embedding in a support appropriate.

L'appareil d'affilage illustré sur les figures 1 à 5 est constitué d'une
platine en métal 1 dans la zone médiane de laquelle est aménagée une
ouverture 2 qui débouche vers le haut. The sharpening device illustrated in Figures 1 to 5 consists of a
Dans la partie supérieure de cette ouverture 2, la platine 1 est équipée
de deux structures rapportées 3 et 4 constituant des supports, d'une part pour
un couple de lames plates 6, 8 destinées à guider la lame de l'outil que l'on
désire affiler, et d'autre part pour deux broches d'affilage 10, 12 qui se croisent
juste devant lesdites lames de guidage 6, 8.In the upper part of this
Le support 3 est illustré isolément sur les figures 6 à 8, et le support 4 sur
les figures 9 à 11 ; ces supports 3 et 4 ont tous les deux la même structure
générale, mais le support 3 est légèrement plus court, de manière à permettre
l'imbrication des deux broches d'affilage 10, 12, comme on le verra plus loin.
Chaque support 3, 4 est en forme générale de U comprenant une embase 14,
une aile arrière 16 et une aile avant 18. Ils s'étendent perpendiculairement au
plan de la platine 1, en saillie vers l'avant, fixés par soudage de leur aile arrière
16 sur ladite platine 1 le long des bordures de l'ouverture 2.
Sur les figures 7 et 10, on remarque la présence d'une échancrure 20
aménagée dans l'aile arrière 16, qui facilite le positionnement correct des
supports 3 et 4 sur une forme complémentaire d'encastrement découpée dans
la platine 1, avant la solidarisation par soudage.
L'embase 14 des supports 3 et 4 comporte un orifice taraudé 22 qui permet la
fixation amovible des lames plates 6 et 8 au moyen d'une vis 24, 26 (figure 4).The

perpendiculaires à la platine support 1.The two sharpening

Les orifices 58 et 60 s'étendent perpendiculairement au plan de la platine

Les deux orifices 58 et 60 sont désaxés pour obtenir un système de
rappel élastique des broches 10 et 12 par un effet de torsion des deux bras
parallèles 48 et 50. Le positionnement des retours 54, 56, et celui des deux
orifices d'accueil 58, 60 est adapté pour obtenir les caractéristiques de rappel
élastiques désirées.
Au repos, les deux bras 48 et 50 des broches 10 et 12 sont parallèles, et l'un de
ces bras a une longueur un peu plus importante que l'autre pour désaxer les
deux retours 54 et 56 afin de permettre leur encastrement dans les orifices 58,
60.
Ces retours 54, 56 sont orientés en sens inverse l'un de l'autre pour que les
deux bras parallèles 48, 50 des broches 10, 12 se positionnent de part et
d'autre des ailes avant 18 des supports 3 et 4, ce positionnement étant possible
grâce à l'élasticité de la liaison d'extrémité 52 desdites broches. Les retours 54
et 56 sont simplement emmanchés dans les orifices 58 et 60, libres de rotation
et amovibles.The two
At rest, the two
These returns 54, 56 are oriented in opposite directions from each other so that the two
Les deux broches d'affilage 10 et 12 sont montées imbriquées l'une dans
l'autre de la manière illustrée sur les figures 1, 3 et 5 pour optimiser les
opérations d'affilage, et aussi pour limiter l'encombrement de l'appareil. Cette
imbrication est ici réalisée grâce à une légère différence de longueur des
supports 3 et 4.The two sharpening
Sur les figures 1, 3 et 5, on remarque la forme générale courbe des deux
broches 10 et 12, qui permet de conserver entre elles un angle de l'ordre de
40°, quelle que soit la profondeur de pénétration de la lame d'outil.In Figures 1, 3 and 5, we note the general curved shape of the two
Au repos, les deux broches d'affilage 10 et 12 sont en position haute,
leur extrémité étant bloquée par des structures de butées 62 aménagées sur
les côtés de la platine 1. Ces butées 62 peuvent être réalisées monobloc, par
pliage des parties latérales de la platine 1 ; elles peuvent aussi être constituées
d'éléments indépendants, rapportés et fixés par tout moyen approprié.
Aux extrémités des butées 62, on remarque la présence d'une petite découpe
64 (figures 1 et 4) structurée pour former une jauge de contrôle permettant à
l'opérateur de vérifier l'usure de la pointe de son couteau.At rest, the two sharpening
Au repos, on remarque que les deux broches d'affilage 10 et 12 se
croisent juste en dessous du niveau de transition entre le Vé évasé 30 et le Vé
resserré 32 des lames de guidage 6 et 8.At rest, we notice that the two sharpening
La platine support 1 a une forme générale triangulaire ; elle peut
comporter des ouvertures internes 66 de part et d'autre de l'ouverture
débouchante 2, qui permettent d'alléger son poids.
En partie inférieure, la platine 1 est munie d'une patte monobloc 68 qui permet
l'encastrement amovible de l'appareil d'affilage dans un support approprié, fixé
sur le poste de travail. L'appareil peut ainsi très facilement être enlevé de son
support, en particulier en vue de son nettoyage ou désinfection.
Une découpe interne 70 aménagée dans la patte monobloc 68 permet encore
d'alléger le poids de l'appareil.The
In the lower part, the
An
Comme cela apparaít sur la figure 12, une fois l'appareil positionné
verticalement sur son support (non représenté), l'opérateur place la lame d'outil
72 qu'il désire affiler entre les deux lames 6 et 8 qui forment un guidage
autoserrant.
S'il désire utiliser le Vé de redressage 42 formé par les deux languettes
monobloc 38 et 40, il exerce une pression verticale sur l'outil, suffisante pour
que sa lame atteigne ledit Vé 42 en écartant les deux broches 10, 12 ;
l'opérateur peut alors exercer les mouvements de va-et-vient adaptés pour
« travailler » le fil de la lame d'outil, d'une manière similaire ou apparentée au
travail classique par un fusil « rugueux ».
La lame d'outil est alors guidée par le Vé autoserrant 32 des lames de guidage
6, 8 qui assure un angle de travail parfait.As shown in Figure 12, once the device positioned vertically on its support (not shown), the operator places the
If he wishes to use the straightening
The tool blade is then guided by the self-tightening
Les deux broches d'affilage 10 et 12 sont ensuite utilisées pour assurer
la finition de l'opération d'affilage, c'est-à-dire pour « brunir » ou lisser la lame
d'outil, comme on peut le faire de manière classique au moyen d'un fusil
« lisse ».
L'opérateur effectue alors des mouvements de va-et-vient de la lame d'outil sur
les deux broches d'affilage 10, 12, en exerçant une pression juste suffisante
pour ne pas atteindre le Vé de redressage 42.
Les deux broches d'affilage 10 et 12 s'apparentent à des barres de torsion
mobiles en forme d'arcs et elles permettent de conserver entre elles, et quelle
que soit la profondeur de pénétration de la lame d'outil dans le Vé resserré 32,
le bon angle d'attaque permettant d'optimiser le travail sur le fil de la lame.The two sharpening
The operator then makes back and forth movements of the tool blade on the two sharpening
The two sharpening
Le mouvement vers le bas de la lame d'outil est limité par la présence du
Vé de redressage 42 et il n'est donc pas nécessaire de prévoir des structures
de butées basses pour les deux broches d'affilage 10 et 12. En tout état de
cause, les deux broches 10 et 12, imbriquées l'une dans l'autre, ne peuvent pas
s'écarter l'une de l'autre en partie inférieure.The downward movement of the tool blade is limited by the presence of the
Straightening ve 42 and it is therefore not necessary to provide structures
low stops for the two sharpening
Les deux broches d'affilage 10 et 12 comportent intrinsèquement leurs
propres moyens de rappel élastiques, ce qui simplifie la structure de l'appareil.
En outre, ces deux broches peuvent très facilement être démontées et
remontées de leur support, en particulier pour les opérations de remplacement
suite à une détérioration, ou simplement pour leur nettoyage. The two sharpening
L'appareil conforme à la présente invention a une structure générale relativement simple et il est très complet puisqu'il propose deux ensembles associés qui permettent de travailler différemment le fil des lames d'outils.The apparatus according to the present invention has a general structure relatively simple and very complete since it offers two sets associated which allow to work differently the wire of the blades of tools.
Le mode de réalisation qui vient d'être décrit est intégralement réalisé en
métal. Bien entendu certaines parties, et notamment la platine 1 ainsi que les
structures supports rapportées 3 et 4 pourraient être obtenues en matière
plastique moulée ; dans ce dernier cas, la fixation des structures supports 3 et 4
sur la platine en matière plastique peut être obtenue au moyen de vis adaptées.The embodiment which has just been described is entirely carried out in
metal. Of course certain parts, and in particular the
