DESCRIPCIONDESCRIPTION
Dispositivo de corte para revestimientos de suelo, ripias de tejado o similares de plastico, goma u otro material tenaz o elastico.Cutting device for floor coverings, roof shingles or similar of plastic, rubber or other tough or elastic material.
La invencion concierne a un dispositivo de corte con una cuchilla de corte fijada de manera basculable en un bastidor y cuyo filo penetra al cortar en una hendidura de penetracion entre dos largueros de soporte con una distancia tipo rendija bilateral entre el lado ancho de la cuchilla de corte y el canto del larguero de soporte, para expulsar una tira de material de una pieza de trabajo de forma de placa que descansa sobre los largueros de soporte.The invention concerns a cutting device with a cutting blade fixed in a tiltable manner on a frame and whose edge penetrates when cutting into a penetration groove between two support stringers with a bilateral slit type distance between the wide side of the cutting blade. cutting and edge of the support stringer, to eject a strip of material from a workpiece in the form of a plate that rests on the support stringers.
Un dispositivo de corte de esta clase se encuentra descrito en el documento DE 10 2009 003 490 A1. El dispositivo de corte posee un bastidor que consta de dos largueros de soporte que discurren paralelos uno a otro y que estan unidos con pies en sus dos extremos. Entre los dos largueros de soporte se extiende una hendidura de penetracion. Una cuchilla de corte montada de manera basculable entre los dos largueros de soporte y cuyo filo presenta dientes puede penetrar en la hendidura de penetracion. Queda entonces una distancia tipo rendija entre los lados anchos de la cuchilla de corte y las paredes de la hendidura de penetracion. Una cuchilla de corte que penetra libremente en la hendidura con algo de descentramiento se centra bajo la carga de corte a consecuencia de la deformacion de la pieza de trabajo en la hendidura, de modo que la distancia tipo rendija es aproximadamente igual en ambos lados de la cuchilla de corte.A cutting device of this class is described in DE 10 2009 003 490 A1. The cutting device has a frame consisting of two support stringers that run parallel to each other and that are joined with feet at both ends. A penetration groove extends between the two support stringers. A cutting blade mounted in a tiltable manner between the two support stringers and whose cutting edge has teeth can penetrate the penetration groove. There is then a gap type gap between the wide sides of the cutting blade and the walls of the penetration groove. A cutting blade that penetrates freely into the groove with some offset is centered under the cutting load as a result of the deformation of the workpiece in the groove, so that the slit type distance is approximately equal on both sides of the groove. cutting blade
Se conocen tambien aparatos de corte de la clase anteriormente mencionada por los documentos FR 575749, FR 612747 A, FR 847014 A, DE 20 2008 015 621 U1, GB 2200070 A, DE 10 2009 043 992 A1, US 2,789,642, GB 693702 y US 2,643,720.Cutting apparatus of the aforementioned class are also known from documents FR 575749, FR 612747 A, FR 847014 A, DE 20 2008 015 621 U1, GB 2200070 A, DE 10 2009 043 992 A1, US 2,789,642, GB 693702 and US 2,643,720.
El aparato de corte citado al principio es adecuado para trocear placas de suelo laminadas. En los dispositivos de corte para placas de suelo laminadas que se encuentran en el mercado, la distancia tipo rendija entre el lado ancho de la cuchilla de corte y el canto del larguero de soporte es de aproximadamente 2 mm a 2,5 mm. Es necesaria una rendija tan grande para mantener pequenas las fuerzas que se producen al expulsar una tira de material de la placa de suelo laminada hacia dentro de la hendidura de penetracion. En el mercado se conocen tambien aparatos de corte para cortar placas laminadas en los que la distancia tipo rendija es inferior a 2 mm y los cuales presentan un mango de longitud poco manejable en la cuchilla de corte.The cutting apparatus mentioned at the beginning is suitable for cutting laminated floor plates. In cutting devices for laminated floor plates that are on the market, the gap-type distance between the wide side of the cutting blade and the edge of the support beam is approximately 2 mm to 2.5 mm. Such a large slit is necessary to keep the forces that are produced by expelling a strip of material from the laminated floor plate into the penetration groove. In the market, cutting apparatuses are also known for cutting laminated plates in which the slit type distance is less than 2 mm and which have a handle of little manageable length in the cutting blade.
La invencion se basa en el problema de perfeccionar el dispositivo de corte en el sentido de que se puedan cortar con el revestimientos de suelo u otras placas de plastico, goma u otro material tenaz o elastico con una calidad de corte suficientemente alta.The invention is based on the problem of perfecting the cutting device in the sense that they can be cut with floor coverings or other plastic, rubber or other tough or elastic material with a sufficiently high cutting quality.
El problema se resuelve con la invencion indicada en la reivindicacion 1. Las reivindicaciones subordinadas representan perfeccionamientos ventajosos.The problem is solved with the invention indicated in claim 1. The subordinate claims represent advantageous improvements.
El lado ancho de la cuchilla de corte esta provisto de un recubrimiento antiadherente. Se proporciona una capacidad de uso universal del dispositivo de corte cuando la distancia tipo rendija es de aproximadamente 0,7 mm. Este valor esta afectado de tolerancias, siendo estas tolerancias relativamente poco cnticas. Es especialmente ventajoso que el filo este provisto de un dentado. La distancia de las crestas de los dientes es en este caso del orden de magnitud del espesor del material de los revestimientos a cortar, es decir que esta entre 1 mm y 5 mm. Sin embargo, la distancia de las crestas de los dientes es preferiblemente superior a 2 mm. Los dientes poseen crestas que se extienden paralelamente al eje de giro de la cuchilla de corte, es decir que discurren perpendicularmente a la normal a las superficies de los lados anchos. Las crestas de los dientes se extienden preferiblemente por todo el espesor del material de la cuchilla de corte y forman asf un filo romo. Sin embargo, las crestas de los dientes pueden estar tambien tan afiladas que discurran oblicuamente con una direccion de bisel cambiante de modo que estas entren reforzadamente por el borde de la tira de corte en la superficie de la pieza de trabajo. Al cortar, estos dientes se clavan en la superficie de la pieza de trabajo que se debe cortar para expulsar la tira de material de la placa de la pieza de trabajo. En este caso, es de importancia que la pieza de trabajo se apoye sobre ambos largueros de soporte. Cuando se deben cortar placas delgadas de material con el dispositivo de corte, es ventajoso que el filo transmita fuerzas horizontales reducidas a la placa de material. Tales fuerzas horizontales, que, siempre que la pieza de trabajo se apoye en un tope, pueden conducir a un alabeo ondulado de la pieza de trabajo, se eliminan preferiblemente haciendo que la cuchilla de corte este montada en el bastidor con posibilidad de basculacion de tal manera que los dientes penetren en la hendidura de penetracion sustancialmente en una direccion transversal al plano de soporte de los largueros de soporte. Se ha previsto preferiblemente para esto un controlador de la cuchilla de corte que hace que el eje de basculacion de la cuchilla de corte se desplace en direccion horizontal en el transcurso del corte. Preferiblemente, una clavija de control asociada estacionariamente al larguero de soporte atraviesa entonces una hendidura arqueada de la cuchilla de corte que discurre a lo largo de una curva espiral. En una ejecucion preferida de la invencion se ha previsto que las paredes de la hendidura de penetracion esten formadas por una superficie frontal de un liston, estando fijado siempre un liston en un nervio perfilado de un larguero de soporte. Se ha previsto tambien que los lados anchos de la hoja de cuchilla y los listones esten provistos de un recubrimiento antiadherente. En particular, las paredes de la hendidura estan provistas de un recubrimientoThe wide side of the cutting blade is provided with a non-stick coating. A universal use capacity of the cutting device is provided when the slit type distance is approximately 0.7 mm. This value is affected by tolerances, these tolerances being relatively low. It is especially advantageous if the cutting edge is provided with a teeth. The distance of the ridges of the teeth is in this case of the order of magnitude of the thickness of the material of the coatings to be cut, that is, between 1 mm and 5 mm. However, the distance of the ridges of the teeth is preferably greater than 2 mm. The teeth have ridges that extend parallel to the axis of rotation of the cutting blade, that is to say that they run perpendicularly to normal to the surfaces of the wide sides. The ridges of the teeth preferably extend over the entire thickness of the material of the cutting blade and thus form a blunt edge. However, the ridges of the teeth can also be so sharp that they run obliquely with a direction of changing bevel so that they enter reinforced by the edge of the cutting strip on the surface of the workpiece. When cutting, these teeth are driven into the surface of the workpiece that must be cut to eject the strip of material from the workpiece plate. In this case, it is important that the work piece rests on both support stringers. When thin plates of material must be cut with the cutting device, it is advantageous for the cutting edge to transmit reduced horizontal forces to the material plate. Such horizontal forces, which, provided that the workpiece is supported by a stop, can lead to a corrugated warping of the workpiece, are preferably eliminated by having the cutting blade mounted on the frame with the possibility of tilting such so that the teeth penetrate the penetration groove substantially in a direction transverse to the support plane of the support stringers. A cutting blade controller is preferably provided for this which causes the tilting axis of the cutting blade to move horizontally in the course of cutting. Preferably, a control pin stationary associated with the support stringer then crosses an arcuate groove of the cutting blade that runs along a spiral curve. In a preferred embodiment of the invention, it is provided that the walls of the penetration groove are formed by a front surface of a slat, a lath always being fixed on a profiled rib of a support member. It is also provided that the wide sides of the blade and the slats are provided with a non-stick coating. In particular, the walls of the slit are provided with a coating

antiadherente. El recubrimiento antiadherente puede consistir en un recubrimiento de silicona o un recubrimiento de PTFE (recubrimiento de Teflon) el recubrimiento puede aplicarse como un barniz. Se trata de un recubrimiento como el que ya es en principio conocido, por ejemplo, por los moldes de panadena. Con un dispositivo configurado de esta manera se pueden cortar losetas recubiertas con adhesivo. Como consecuencia del recubrimiento antiadherente de la hoja de cuchilla y los listones, se reduce allf una adherencia del adhesivo. El dentado de la cuchilla de corte puede estar provisto tambien de un recubrimiento antiadherente. Particularmente con anchos de hendidura muy pequenos se impide un pegado involuntario entre la pared de la hendidura y el lado ancho de la cuchilla de corte o el dentado de la cuchilla de corte. El dispositivo es adecuado tambien para trocear placas de pizarra.non-stick The non-stick coating may consist of a silicone coating or a PTFE coating (Teflon coating) the coating can be applied as a varnish. It is a coating like the one that is already known in principle, for example, for panadena molds. With a device configured in this way, adhesive coated tiles can be cut. As a result of the non-stick coating of the blade and the slats, there is reduced adhesion of the adhesive. The teeth of the cutting blade can also be provided with a non-stick coating. Particularly with very small slit widths, involuntary bonding between the wall of the slit and the wide side of the cutting blade or the teeth of the cutting blade is prevented. The device is also suitable for cutting slate plates.
Se explica seguidamente un ejemplo de realizacion de la invencion ayudandose de los dibujos adjuntos. Muestran:An example of embodiment of the invention is explained below using the attached drawings. They show:

El dispositivo de corte representado en las figuras corresponde sustancialmente al que se ha descrito en el documento DE 10 2009 003 490 A1, por lo que se hace referencia a este documento en lo que respecta a la configuracion especial del bastidor, la cuchilla de corte y especialmente su apoyo en los dos largueros de soporte. Por este motivo, el contenido divulgativo del documento DE 10 2009 003 490 A1 se incorpora tambien con toda su extension en esta solicitud.The cutting device shown in the figures corresponds substantially to that described in DE 10 2009 003 490 A1, whereby reference is made to this document with regard to the special configuration of the frame, the cutting blade and especially its support in the two support stringers. For this reason, the informative content of document DE 10 2009 003 490 A1 is also incorporated with all its extension in this application.
Los dibujos muestran un bastidor 1 que posee dos pies 3 que estan dispuestos cada uno de ellos en el extremo de dos largueros de soporte 2 paralelos uno a otro y que mantienen los largueros de soporte 2 a distancia uno de otro. La distancia de los dos largueros de soporte 2 define una hendidura de penetracion 6.The drawings show a frame 1 that has two feet 3 that are each arranged at the end of two support beams 2 parallel to each other and that keep the support beams 2 at a distance from each other. The distance of the two support stringers 2 defines a penetration groove 6.
En un extremo de los dos largueros de soporte 2 esta conectada de manera basculable alrededor de un punto de articulacion 15 una cuchilla de corte 10 que consta de una hoja de acero. La cuchilla de corte 10 posee un filo 12 que discurre sobre un arco y que esta provisto de un gran numero de dientes 13. Los dientes 13 poseen crestas que discurren paralelas a la normal a las superficies 11 de los lados anchos de la cuchilla de corte 10 y que se extienden por todo el espesor del material de la cuchilla de corte 10.At one end of the two support stringers 2 a cutting blade 10 consisting of a steel blade is pivotally connected around an articulation point 15. The cutting blade 10 has a cutting edge 12 that runs over an arc and is provided with a large number of teeth 13. The teeth 13 have ridges that run parallel to the surfaces normal to the surfaces 11 of the wide sides of the cutting blade 10 and which extend over the entire thickness of the material of the cutting blade 10.
El espesor del material de la cuchilla de corte 10 es mayor que la mitad de la distancia entre las dos paredes 4 de la hendidura que definen la anchura de la hendidura de penetracion 6. En el ejemplo de realizacion las paredes 4 de la hendidura estan formadas por unos listones 5 que estan enchufados sobre nervios perfilados 7 realizados en forma de cola de milano de los largueros de soporte 2 consistentes en aluminio.The thickness of the material of the cutting blade 10 is greater than half the distance between the two walls 4 of the groove that define the width of the penetration groove 6. In the embodiment example the walls 4 of the groove are formed by slats 5 that are connected on profiled ribs 7 made in the form of a dovetail of the support stringers 2 consisting of aluminum.
La figura 3 muestra que los listones 5 forman unos cantos 4'. Se trata en este caso de cantos 4' de los largueros de soporte en los que se puede apoyar la pieza de trabajo 9 que se debe cortar. Se puede apreciar tambien en la figura 3 que cada uno de los dos lados anchos 11 de la cuchilla de corte 10 introducida en la hendidura de penetracion 6 posee una distancia tipo rendija con respecto al canto 4' del larguero de soporte. Dado que las paredes 4 de la hendidura discurren paralelas una a otra, las paredes 4 de la hendidura tienen la misma distancia tipo rendija al lado ancho 11 de la cuchilla de corte 10 que la que posee tambien el canto 4' del larguero de soporte.Figure 3 shows that the slats 5 form edges 4 '. In this case, it is 4 'edges of the support stringers on which the workpiece 9 to be cut can be supported. It can also be seen in Figure 3 that each of the two wide sides 11 of the cutting blade 10 inserted in the penetration groove 6 has a gap-like distance with respect to the edge 4 'of the support member. Since the walls 4 of the groove run parallel to each other, the walls 4 of the groove have the same slit-type distance to the wide side 11 of the cutting blade 10 as that which also has the edge 4 'of the support stringer.
En los dibujos se puede apreciar tambien que esta dispuesto un tope giratorio 8 sobre los largueros de soporte 2. Este tope 8 es sustancialmente una ayuda de ajuste. A causa del dentado del filo 12, cuyos dientes 13 penetran al cortar en la pieza de trabajo 9, apenas se desplaza la pieza de trabajo 9 al cortarla sobre los largueros de soporte 2. La articulacion 15 esta configurada del modo que se ha descrito en el documento DE 10 2009 043 992 A1. Se impide entonces enteramente un desplazamiento de la pieza de trabajo 9 al realizar el corte. Por este motivo, el documento DE 10 2009 043 992 A1 se incorpora tambien con todo su contenido en esta solicitud en lo que respecta a la configuracion del soporte de basculacion 15. Los elementos esenciales de la articulacion 15 estan representados en las figuras 5 y 6. El eje de basculacion 17 (alrededor del cual puede bascular la cuchilla de corte 10) esta ciertamente fijado con gran solidez a la cuchilla de corte 10, pero puede trasladarse en una hendidura horizontal 18 del larguero de soporte 2. Un munon de control 19, que esta fijado con gran solidez al bastidor 1 o a los largueros de soporte 2, atraviesa una hendidura arqueada 16 de la cuchilla de corte 10. La hendidura arqueada 16 discurre sobre una curva espiral, referido al munon 17 que forma el eje de basculacion. En la posicion de funcionamiento representada en la figura 5, en la que la cuchilla de corte esta basculada hacia arriba, el munon 17 tiene la distancia mas pequena al munon de control 19. Si se hace que bascule la cuchilla de corte 10, el munon deIn the drawings it can also be seen that a rotating stop 8 is arranged on the support beams 2. This stop 8 is substantially an adjustment aid. Because of the cutting edge of the cutting edge 12, whose teeth 13 penetrate when cutting in the workpiece 9, the workpiece 9 is hardly moved when it is cut on the support stringers 2. The articulation 15 is configured in the manner described in DE 10 2009 043 992 A1. A displacement of the workpiece 9 is then completely prevented when cutting. For this reason, document DE 10 2009 043 992 A1 is also incorporated with all its content in this application with regard to the configuration of the tilting support 15. The essential elements of the articulation 15 are represented in Figures 5 and 6 The tilting shaft 17 (around which the cutting blade 10 can swing) is certainly fixed very firmly to the cutting blade 10, but can be moved in a horizontal groove 18 of the support beam 2. A control munon 19 , which is fixed with great solidity to the frame 1 or to the support stringers 2, crosses an arcuate groove 16 of the cutting blade 10. The arcuate groove 16 runs on a spiral curve, referred to the munon 17 that forms the tilt axis. In the operating position shown in Figure 5, in which the cutting blade is tilted upwards, the munon 17 has the smallest distance to the control world 19. If the cutting blade 10 is made to swing, the munon from

control 19 recorre entonces la hendidura arqueada 16, ampliandose la distancia entre el eje de basculacion 17 y el munon de control 19. Esto tiene la consecuencia de que el eje de basculacion 17 se mueve durante el corte en la hendidura horizontal 18, es decir, en la direccion de la extension de los largueros de soporte 2. Esto tiene para el corte la consecuencia de que el diente designado en la figura 4 con el numero de referencia 13 se desplaza durante 5 el corte sustancialmente solo hacia abajo, es decir, en una direccion transversal a la direccion de la extension del larguero de soporte 2. Por tanto, no se ejercen fuerzas dirigidas en direccion horizontal sobre la pieza de trabajo 9. Se pueden cortar asf tambien piezas de trabajo 9 de pared delgada sin que estas produzcan ondulaciones.control 19 then travels the arcuate groove 16, the distance between the tilt axis 17 and the control munon 19 being enlarged. This has the consequence that the tilt axis 17 moves during the cut in the horizontal groove 18, that is, in the direction of the extension of the support stringers 2. This has for the cut the consequence that the tooth designated in figure 4 with the reference number 13 moves for 5 the cut substantially only downwards, that is, in a direction transverse to the direction of the extension of the support beam 2. Therefore, no horizontally directed forces are exerted on the workpiece 9. Workpieces 9 of thin wall can also be cut without these causing ripples .
