El cometido de la invencion es crear una cuchilla circular, con la que son posibles diferentes profundidades de corte.The purpose of the invention is to create a circular blade, with which different depths of cut are possible.
El cometido se soluciona en una cuchilla circular por medio de las caractensticas de la reivindicacion 1. Las configuraciones favorables y las ventajas de la invencion se deducen a partir de las otras reivindicaciones, de la descripcion y del dibujo.The task is solved in a circular blade by means of the features of claim 1. The favorable configurations and advantages of the invention are deduced from the other claims, the description and the drawing.
Se propone una cuchilla circular para la realizacion de una trayectoria de corte, con un cuerpo de cuchillas, cuya periferia exterior presenta una corona dentada, en la que dientes y espacios intermedios de los dientes con fundos de dientes se suceden alternando entre sf. El cuerpo de cuchillas esta formado por al menos dos cuchillas parciales, en el que la separacion de las al menos dos cuchillas parcial esta prevista transversalmente al eje de giro del cuerpo de cuchillas. Una primera de las cuchillas parciales presenta una corona dentada, en la que los dientes estan configurados como cantos de corte y los fondos de los dientes no estan configurados como cantos de corte, y una segunda de las cuchillas parciales presenta una corona dentada, cuyos dientes y fondos de los dientes estan configurados como cantos de corte.A circular blade is proposed for the realization of a cutting path, with a body of blades, whose outer periphery has a toothed crown, in which teeth and intermediate spaces of the teeth with tooth covers occur in alternating between sf. The blade body is formed by at least two partial blades, in which the separation of the at least two partial blades is provided transversely to the axis of rotation of the blade body. A first of the partial blades has a toothed crown, in which the teeth are configured as cutting edges and the bottoms of the teeth are not configured as cutting edges, and a second of the partial blades has a toothed crown, whose teeth and teeth bottoms are configured as cutting edges.
La cuchilla circular rueda a lo largo de la trayectoria de corte sobre la superficie del producto a cortar, por ejemplo carton ondulado. Con ventaja con la cuchilla circular se pueden realizar cortes en dos profundidades de corte. En particular, es posible generar una trayectoria de corte en el carton ondulado sobre los dos lados, aunque la cuchilla circular solamente esta apoyada en un lado. En este caso, la capa exterior del carton ondulado es cortada totalmente sobre el lado, en el que incide la cuchilla circular y el lado opuesto solo el perforado por los dientes de la cuchilla. Si la cuchilla circular colabora con espaciador, se puede ajustar exactamente la profundidad de penetracion de la cuchilla circular.The circular blade rolls along the cutting path on the surface of the product to be cut, for example corrugated cardboard. With advantage with the circular blade you can make cuts at two depths of cut. In particular, it is possible to generate a cutting path in the corrugated cardboard on both sides, although the circular blade is only supported on one side. In this case, the outer layer of the corrugated cardboard is cut completely on the side, on which the circular blade and the opposite side only pierced by the teeth of the blade. If the circular blade collaborates with a spacer, the penetration depth of the circular blade can be adjusted exactly.
De acuerdo con una configuracion ventajosa, las al menos dos cuchillas parciales pueden presentar dientes y espacios intermedios de los dientes y pueden ser giratorias entre sf alrededor del eje de giro del cuerpo de cuchillas. Si se giran las al menos dos cuchillas parciales una con relacion a la otra, se pueden ajustar diferentes distancias de los cantos de corte de las cuchillas parciales y, por lo tanto, diferentes profundidades de corte de la cuchilla.According to an advantageous configuration, the at least two partial blades can have teeth and intermediate spaces of the teeth and can be rotated between them around the axis of rotation of the blade body. If the at least two partial blades are turned relative to each other, different distances of the cutting edges of the partial blades and, therefore, different depths of cutting the blade can be adjusted.
De acuerdo con una configuracion favorable, los cantos de corte de los dientes pueden estar configurados curvados tangencialmente a la periferia o a lo largo de la periferia. De esta manera, se puede realizar un corte, que se extiende esencialmente perpendicular a una superficie del carton ondulado que se encuentra adyacente a la duchilla circular. Se puede evitar un corte de traccion, en el que un canto de corte es estirado en la direccion de corte a traves del carton ondulado, lo que puede conducir a grietas y roturas y similares.According to a favorable configuration, the cutting edges of the teeth can be configured tangentially curved to the periphery or along the periphery. In this way, a cut can be made, which extends essentially perpendicular to a corrugated cardboard surface that is adjacent to the circular shower. A traction cut can be avoided, in which a cutting edge is stretched in the direction of cut through the corrugated cardboard, which can lead to cracks and breaks and the like.
De acuerdo con una configuracion favorable, la corona dentada puede estar biselada en direccion radial hacia fuera al menos en un lado plano del cuerpo de cuchillas. En particular, la corona dentada puede estar biselada en ambos lados planos del cuerpo de cuchillas. De esta manera resulta un canto de corto afinado definido en los dientes y/o en el fondo del diente.According to a favorable configuration, the toothed crown may be beveled radially outwardly at least on a flat side of the blade body. In particular, the crown gear can be beveled on both flat sides of the blade body. This results in a short-tuned edge defined on the teeth and / or the bottom of the tooth.
De acuerdo con una configuracion favorable, la primera de las cuchillas parciales puede presentar una periferia mayor que la segunda de las cuchillas parciales. De esta manera esta previsto un tamano definido de duchilla. Uno o varios cantos de corte con las diferentes profundidades de corte se pueden preparar en los espacios intermedios de los dientes de la primera cuchilla parcial, cuyos fondos de los dientes no estan configurados como cantos de corte.According to a favorable configuration, the first of the partial blades may have a periphery greater than the second of the partial blades. In this way a defined size of shower is provided. One or several cutting edges with different depths of cut can be prepared in the intermediate spaces of the teeth of the first partial blade, whose bottoms of the teeth are not configured as cutting edges.
De acuerdo con una configuracion favorable, los dientes de la segunda de las cuchillas parciales pueden ser tan anchos que llenan los espacios intermedios de los dientes de la primera de las cuchillas parciales. De esta manera, se pueden conseguir dimensiones definidas de la perforacion asf como un posicionamiento definido de las cuchillas parciales entre sfAccording to a favorable configuration, the teeth of the second of the partial blades can be so wide that they fill the intermediate spaces of the teeth of the first of the partial blades. In this way, defined dimensions of the perforation can be achieved as well as a defined positioning of the partial blades between sf

De acuerdo con una configuracion favorable, los fondos de los dientes de la segunda de las cuchillas parciales pueden ser al menos tan anchos que llenan los espacios intermedios de los dientes de la primera de las cuchillas parciales. De esta manera se pueden conseguir dimensiones definidas de la perforacion as^ como un posicionamiento definido de las cuchillas parciales entre sfAccording to a favorable configuration, the bottoms of the teeth of the second of the partial blades can be at least so wide that they fill the intermediate spaces of the teeth of the first of the partial blades. In this way, defined dimensions of the perforation can be achieved as well as a defined positioning of the partial blades between them.
De acuerdo con una configuracion favorable, los dientes de los dientes de las cuchillas parciales presentan uno o varios medios de marcacion, para indicar de manera definida una primera y/o segunda posicion de las cuchillas parciales entre sf Las cuchillas parciales se pueden posicionar de manera definida para diferentes profundidades de corte. Esto se puede realizar de manera ventajosa a traves de posicionamiento manual por medio de control optico con la ayuda de uno o varios medios de marcacion.According to a favorable configuration, the teeth of the teeth of the partial blades have one or several marking means, to define in a defined way a first and / or second position of the partial blades between them. The partial blades can be positioned so defined for different depths of cut. This can be done advantageously through manual positioning by means of optical control with the help of one or several marking means.
La cuchilla circular de acuerdo con la invencion se puede utilizar en maquinas de corte o maquinas de perforacion, o en herramientas manuales.The circular blade according to the invention can be used in cutting machines or drilling machines, or in hand tools.

La cuchilla circular 10 presenta un cuerpo de cuchillas 12, que esta compuesto en direccion axial por cuchillas parciales, aqu por una primera cuchilla parcial 40 y una segunda cuchilla parcial 50, estan apoyadas entre sf con sus lados planos. La figura 1 muestra la cuchilla circular 10 como vista lateral, las figuras 2 y 3 muestran las cuchillas parciales 40, 50 en representacion isometrica. Las cuchillas parciales 40, 50 son giratorias una con relacion a la otra.Figures 1 to 3 show for the illustration of the invention an embodiment of a circular blade 10 can be rotatably operated with different depths of cut. The circular blade 10 has a blade body 12, which is composed in the axial direction by partial blades, here by a first partial blade 40 and a second partial blade 50, are supported with each other with their flat sides. Figure 1 shows the circular blade 10 as a side view, Figures 2 and 3 show the partial blades 40, 50 in isometric representation. Partial blades 40, 50 are rotatable relative to each other.
La primera cuchilla parcial 40 tiene un cuerpo de cuchilla parcial en forma de disco con un orificio central 28, en el que en la periferia exterior del cuerpo de cuchilla parcial esta prevista una corona dentada 48, en el que dientes 42 y espacios intermedios de los dientes 44 se suceden a distancia uniforme entre sf. Los dientes 42 estan configurados en la vista en planta superior esencialmente como cunas de forma rectangular. En el orificio central 28 esta previsto un pivote como medio de marcacion 62, con el que se puede determinar una posicion rotatoria de la cuchilla parcial 40, con respecto a su eje de giro. El medio de marcacion puede estar configurado de manera adecuada tambien de otra forma, por ejemplo como ranura, entalladura o similar.The first partial blade 40 has a partial blade body in the form of a disc with a central hole 28, in which a toothed crown 48 is provided on the outer periphery of the partial blade body, in which teeth 42 and intermediate spaces of the teeth 44 follow each other at a uniform distance from each other. The teeth 42 are configured in the top plan view essentially as rectangular shaped cribs. In the central hole 28 a pivot is provided as a marking means 62, with which a rotary position of the partial blade 40 can be determined, with respect to its axis of rotation. The marking means can also be properly configured in another way, for example as a groove, notch or the like.
La segunda cuchilla parcial 50 tiene un cuerpo de cuchilla parcial en forma de disco con un orificio central 28, en el que en la periferia exterior del cuerpo de cuchilla parcial esta prevista una corona dentada 58, en el que dientes 52 y espacios intermedios de los dientes 54 se suceden alternando a distancia de manera uniforme entre sf. Los dientes 52 estan configurados en la vista en planta superior esencialmente como cunas de forma rectangular. En el orificio central 28 estan previstos dos pivotes como medios de marcacion 64, 66, con los que se puede determinar una posicion rotatoria de la cuchilla parcial 50, con respecto a su eje de giro.The second partial blade 50 has a disc-shaped partial blade body with a central hole 28, in which on the outer periphery of the partial blade body a toothed crown 58 is provided, in which teeth 52 and intermediate spaces of the teeth 54 follow each other alternating evenly between each other. The teeth 52 are configured in the top plan view essentially as rectangular shaped cribs. In the central hole 28 two pivots are provided as marking means 64, 66, with which a rotary position of the partial blade 50 can be determined, with respect to its axis of rotation.

La profundidad de corte de la cuchilla circular 10 se puede modificar, girando las cuchillas parciales 40, 50 una con relacion a la otra, por ejemplo, alrededor de una anchura de un diente.The cutting depth of the circular blade 10 can be modified by rotating the partial blades 40, 50 relative to each other, for example, about a width of a tooth.
La primera cuchilla parcial 40 presenta cantos de corte en los dos extremos libres de los dientes 42, mientras que los fondos de los dientes 46 no presentan cantos de corte. La segunda cuchilla 50 presenta cantos de corte tanto en los extremos libres de los dientes 52 como tambien en los fondos de los dientes 56. La primera cuchilla parcial 40 presenta una periferia mayor que la segunda cuchilla parcial 50.The first partial blade 40 has cutting edges at the two free ends of the teeth 42, while the bottoms of the teeth 46 do not have cutting edges. The second blade 50 has cutting edges both at the free ends of the teeth 52 and also at the bottoms of the teeth 56. The first partial blade 40 has a periphery greater than the second partial blade 50.
Los cantos de corte de los dientes 42, 52 se pueden extender curvados tangencialmente a la periferia o a lo largo de la periferia de la cuchilla parcial 40. De esta manera se evita un corte de traccion, que puede conducir a roturas del material o grietas. Los dientes 42, 52 pueden presentar, por ejemplo, una superficie de base de forma trapezoidal.The cutting edges of the teeth 42, 52 can be extended tangentially curved to the periphery or along the periphery of the partial blade 40. This avoids a traction cut, which can lead to breakage of the material or cracks. The teeth 42, 52 may have, for example, a trapezoidal base surface.
El orificio central 28 sirve para la fijacion de la cuchilla circular 10 en un porta-herramientas de una maquina o de una herramienta manual (no representada), con la que se grna la cuchilla circular 10 a lo largo de un producto a procesar, por ejemplo carton ondulado. En particular, la cuchilla circular 10 puede ser accionada de forma giratoria, de modo que rueda a lo largo de la superficie del producto a procesar y en este caso genera un corte de perforacion. En este caso, los cantos de corte de los dientes 42, 52 y de los fondos de los dientes 46, 56 perforan la capa exterior totalmente y una zona proxima a la capa exterior de la capa intermedia ondulada, cuya capa exterior y capa interior estan distanciadas, mientras que la capa interior solo es perforada por los cantos de corte de los dientes 42, 52.The central hole 28 serves to fix the circular blade 10 in a tool holder of a machine or of a hand tool (not shown), with which the circular blade 10 is milled along a product to be processed, by example corrugated cardboard. In particular, the circular blade 10 can be rotatably driven, so that it rolls along the surface of the product to be processed and in this case generates a perforation cut. In this case, the cutting edges of the teeth 42, 52 and of the bottoms of the teeth 46, 56 pierce the outer layer completely and an area close to the outer layer of the wavy intermediate layer, whose outer layer and inner layer are distanced, while the inner layer is pierced only by the cutting edges of the teeth 42, 52.
Las anchuras de los dientes 42, 52 y de los espacios intermedios de los dientes 44, 54 estan configuradas en este ejemplo aproximadamente iguales. En caso necesario, estas pueden presentar diferentes anchuras segun la imagen de corte deseada y/o el material a cortar.The widths of the teeth 42, 52 and the intermediate spaces of the teeth 44, 54 are approximately equal in this example. If necessary, these can have different widths according to the desired cutting image and / or the material to be cut.
Para una profundidad de corte reducida, se giran las dos cuchillas parciales 40, 50 entre sf, de tal manera que los dientes 52 de la segunda cuchilla parcial 50 estan dispuestos entre los dientes 42 de la primera cuchilla parcial 40. Para una profundidad de corte grande, se giran adicionalmente las dos cuchillas parciales 40, 50 en la medida de la anchura de un diente, de modo que los fondos de los dientes 56 de la segunda cuchilla parcial 50 estan dispuestos entre los dientes 42 de la primera cuchilla parcial 40. La posicion rotatoria de las dos cuchillas parciales 40, 50 entre sf se puede leer tambien en la posicion de los medios de marcacion 62, 64, 66 entre sfFor a reduced depth of cut, the two partial blades 40, 50 are rotated between each other, such that the teeth 52 of the second partial blade 50 are arranged between the teeth 42 of the first partial blade 40. For a depth of cut large, the two partial blades 40, 50 are further rotated to the extent of the width of a tooth, so that the bottoms of the teeth 56 of the second partial blade 50 are disposed between the teeth 42 of the first partial blade 40. The rotary position of the two partial blades 40, 50 between them can also be read in the position of the marking means 62, 64, 66 between them
La figura 4 muestra la aplicacion de una perforacion en un carton ondulado fino 100, por ejemplo de un envase exterior, con la cuchilla circular 10 de la figura 1, y la figura 5 muestra la aplicacion de una perforacion en un carton ondulado grueso 100 con la cuchilla circular 10 de la figura 1 con cuchillas parciales 40, 50 giradas de manera adecuada.Figure 4 shows the application of a perforation in a thin corrugated cardboard 100, for example of an outer container, with the circular blade 10 of Figure 1, and Figure 5 shows the application of a perforation in a thick corrugated cardboard 100 with the circular blade 10 of Figure 1 with partial blades 40, 50 rotated properly.
En la figura 4 se puede reconocer que para cortar un carton ondulado de una capa o bien fino, se giran las cuchillas parciales 40, 50 en la cuchilla circular 10 relativamente entre sf, de tal manera que los cantos de corte en los dientes 52 de la cuchilla parcial 50 estan dispuestos en espacios intermedios de los dientes 42 de la cuchilla parcial 40, de manera que la distancia de los cantos de corte en los dientes 42, 52 es reducida.In Figure 4 it can be recognized that in order to cut a corrugated cardboard of a thin or thin layer, the partial blades 40, 50 are rotated in the circular blade 10 relative to each other, such that the cutting edges in the teeth 52 of The partial blade 50 is arranged in intermediate spaces of the teeth 42 of the partial blade 40, so that the distance of the cutting edges in the teeth 42, 52 is reduced.
A traves de la distancia reducida entre los cantos de corte de las cuchillas parciales 40, 50, la cuchilla circular 10 puede cortar totalmente durante la rodadura sobre la capa exterior 110 del carton ondulado fino la capa exterior 110 con los dientes 42 de la primera cuchilla parcial 40 y los dientes 52 de la segunda cuchilla parcial 50 y puede cortar en gran medida la capa intermedia 112, mientras que la capa interior 120 solo es perforada por los cantos de corte en los dientes 42 de la primera cuchilla parcial 42.Through the reduced distance between the cutting edges of the partial blades 40, 50, the circular blade 10 can completely cut during the rolling on the outer layer 110 of the thin corrugated cardboard the outer layer 110 with the teeth 42 of the first blade partial 40 and the teeth 52 of the second partial blade 50 and can largely cut the intermediate layer 112, while the inner layer 120 is only perforated by the cutting edges in the teeth 42 of the first partial blade 42.
En la figura a la derecha del medio de marcacion 62 de la primera cuchilla parcial 40 se puede reconocer el medio de marcacion 64 de la segunda cuchilla parcial 50, de manera que el medio de marcacion 62 cubre el segundo medio de marcacion 66 de la segunda cuchilla parcial 50.In the figure to the right of the marking means 62 of the first partial blade 40, the marking means 64 of the second partial blade 50 can be recognized, so that the marking means 62 covers the second marking means 66 of the second partial blade 50.
En la figura 5 se puede reconocer que para cortar un carton ondulado de dos o mas capas o bien grueso, las cuchillas parciales 40, 50 en la cuchilla circular 10 estan giradas entre sf, de tal manera que los cantos de corte estan dispuestos en los fondos de los dientes 56 de la cuchilla parcial 50 en los espacios intermedios de los dientes 42 de la cuchilla parcial 40, de manera que la distancia de los cantos de corte en los dientes 42, 52 es grande.In Figure 5 it can be recognized that in order to cut a corrugated cardboard of two or more layers or thick, the partial blades 40, 50 in the circular blade 10 are rotated between each other, such that the cutting edges are arranged in the bottoms of the teeth 56 of the partial blade 50 in the intermediate spaces of the teeth 42 of the partial blade 40, so that the distance of the cutting edges in the teeth 42, 52 is large.
Debido a la distancia grande entre los cantos de corte de las cuchillas parciales 40, 50, la cuchilla circular 10 puede perforar durante la rodadura sobre la capa exterior 110 el carton ondulado grueso con un ajusta con distancia grande entre los cantos de corte de las dos cuchillas parciales 40, 50. El carton ondulado presenta entre la capa exterior 110 y la capa interior 120 dos capas intermedias 112, 116, que estan separadas por una capa intermedia 114. La capa exterior 110 y la primera capa intermedia 112 asf como la capa intermedia 114 se separan totalmente por los cantos de corte de los dientes 42 de la primera cuchilla parcial 40 y por los cantos de corte en los fondos de los dientes 56 de la segunda cuchilla parcial 50, mientras que la capa interior 120 y la segunda capa intermedia 116 solamente son perforadas por los cantos de corte en los fondos de los dientes 56 de la primera cuchilla parcial 50.Due to the large distance between the cutting edges of the partial blades 40, 50, the circular blade 10 can perforate the thick corrugated cardboard during rolling on the outer layer 110 with a large distance adjustment between the cutting edges of the two partial blades 40, 50. The corrugated cardboard has between the outer layer 110 and the inner layer 120 two intermediate layers 112, 116, which are separated by an intermediate layer 114. The outer layer 110 and the first intermediate layer 112 as well as the layer intermediate 114 are completely separated by the cutting edges of the teeth 42 of the first partial blade 40 and by the cutting edges at the bottoms of the teeth 56 of the second partial blade 50, while the inner layer 120 and the second layer intermediate 116 are only pierced by the cutting edges on the bottoms of the teeth 56 of the first partial blade 50.
En la figura, a la izquierda del medio de marcacion 62 de la primera cuchilla parcial 40 se puede reconocer el medio de marcacion 66 de la segunda cuchilla parcial 50, de manera que el medio de marcacion 62 cubre el segundo medio de marcacion 64 de la segunda cuchilla parcial 50.In the figure, on the left of the marking means 62 of the first partial blade 40, the marking means 66 of the second partial blade 50 can be recognized, so that the marking means 62 covers the second marking means 64 of the second partial blade 50.
