Antecedentes de la invenciónBackground of the invention

Como es bien sabido, las herramientas de corte y en particular las cortadoras de espiga para montar en máquinas CNC y realizar taladros, ranuras o canales en la superficie de un tablero hecho de madera o sus derivados, tal como aglomerados o contrachapados, generalmente se componen de un vástago que se conecta con el eje de la máquina-herramienta y un cuerpo de corte dotado de uno o más filos.As is well known, cutting tools and in particular the spindle cutters for mounting on CNC machines and drill holes, grooves or channels on the surface of a board made of wood or its derivatives, such as agglomerates or plywood, usually made up of a stem that connects to the axis of the machine tool and a cutting body equipped with one or more edges.

Un inconveniente de las soluciones conocidas antes comentadas reside en el hecho de que, en las operaciones de corte, no es fácil quitar las virutas de la zona de trabajo, debido a la dimensión de la longitud discontinua, o peor, continua de la viruta de madera; en algunos casos la viruta se enrosca en el cuerpo cortante, causando pérdida de eficacia en la operación de corte y reducción de la vida media del filo.A drawback of known solutions mentioned above lies in the fact that, in the operations of cutting, it is not easy to remove the chips from the work area, because to the dimension of the discontinuous length, or worse, continuous of the wood chip; in some cases the chip curls in the body sharp, causing loss of efficiency in the cutting operation and reduction of the half-life of the edge.

Descripción de una realización de la invenciónDescription of an embodiment of the invention

Con referencia a las figuras antes mencionadas, una herramienta de corte 1 con arreglo a la invención presente comprende un vástago 2 para conectar con el eje de una máquina-herramienta y un cuerpo de corte 3, dotado de uno o varios medios de corte que salen a lo largo del eje longitudinal A del cuerpo de corte 3; disponiendo cada medio de corte de un filo; en una versión preferente, como se ve en las figuras adjuntas, el cuerpo de corte 3 tiene dos medios de corte 4, 5 teniendo un filo cada uno, respectivamente 6 y 7; los medios de corte 4, 5 están puestos en lados opuestos del cuerpo de corte 3 y escalonados de modo que formen un ángulo de anzuelo de 30º; como es sabido por los textos técnicos, el ángulo de anzuelo es el formado entre la línea que une los dos filos 6, 7 y la línea que, en el mismo plano, forma la cara frontal 8 ó 9 de uno de los medios de corte 4, 5 definido por la inclinación de la sección transversal de la cara frontal de uno de los medios de corte 4, 5.With reference to the aforementioned figures, a cutting tool 1 according to the present invention comprises a rod 2 to connect with the axis of a machine tool and a cutting body 3, equipped of one or several cutting means that exit along the axis longitudinal A of the cutting body 3; disposing every means of cutting an edge; in a preferred version, as seen in the attached figures, the cutting body 3 has two cutting means 4, 5 having an edge each, respectively 6 and 7; the means of cutting 4, 5 are placed on opposite sides of the cutting body 3 and staggered so that they form a hook angle of 30º; How is it known by technical texts, the hook angle is formed between the line that joins the two edges 6, 7 and the line that, in the same plane, forms the front face 8 or 9 of one of the means of section 4, 5 defined by the inclination of the cross section of the front face of one of the cutting means 4, 5.

Cada medio de corte 4, 5 tiene una cara frontal, respectivamente 8, 9 dispuesta para hacer contacto con el tablero de madera que se va a cortar; las caras frontales van unidas a un lado del cuerpo de corte 3 y forman a cada lado, los filos 6, 7 respectivamente; dos rebajes longitudinales 10, 11 respectivamente, se extienden a lo largo de por lo menos una parte de las caras frontales 8, 9, como se ve en la figura 4; los rebajes 10, 11 respectivamente preferiblemente van desde el extremo libre de la cara frontal 8 ó 9 respectivamente, hasta el otro extremo frente al vástago 2; la parte final de los rebajes 10, 11 frente al vástago 2 están dirigidas hacia fuera en el sentido de los filos 6, 7 respectivamente.Each cutting means 4, 5 has a front face, respectively 8, 9 arranged to make contact with the board of wood to be cut; the front faces are attached to one side of the cutting body 3 and form on each side, the edges 6, 7 respectively; two longitudinal recesses 10, 11 respectively, they extend along at least part of the faces front 8, 9, as seen in figure 4; the recesses 10, 11 respectively preferably they go from the free end of the front face 8 or 9 respectively, to the other end facing the stem 2; the final part of the recesses 10, 11 in front of the stem 2 they are directed outward in the direction of the edges 6, 7 respectively.

El objeto de los rebajes 10, 11 es romper las virutas de madera y facilitar su retirada de la zona de trabajo; en efecto, durante la operación de corte, las virutas de madera que cortan los filos 6, 7 topan con el fondo de los rebajes 10, 11. Ese choque, al que sigue un cambio brusco de dirección a lo largo de las caras frontales 8, 9 rompe las virutas en pedazos de muy pequeño tamaño, incluso las pulveriza; entonces, los rebajos 10, 11 empujan los trozos más pequeños, o pulverizados longitudinalmente por las caras frontales 8, 9, que son retirados de la zona de trabajo y de la herramienta de corte gracias a la inclinación hacia fuera de los rebajes 10, 11.The purpose of the recesses 10, 11 is to break the wood chips and facilitate removal from the work area; in effect, during the cutting operation, the wood chips that they cut the edges 6, 7 run into the bottom of the recesses 10, 11. That shock, which is followed by a sharp change of direction along the front faces 8, 9 breaks the chips into very small pieces size, even sprays them; then, rebates 10, 11 push the smaller pieces, or pulverized longitudinally by the front faces 8, 9, which are removed from the work area and from the cutting tool thanks to the tilt out of the recesses 10, 11.

En la descripción anterior se ha demostrado que la herramienta de corte con arreglo a la presente invención consigue las metas y objetivos antes citados; de hecho, se ha dispuesto de una herramienta de corte de tableros de madera, particularmente una cortadora de espiga para montar en máquinas CNC, que supera los inconvenientes y limitaciones que sufren las soluciones conocidas por la técnica anterior; en efecto, la herramienta de corte antes descrita, gracias a estar provista de los rebajes 10, 11, es capaz de reducir considerablemente la longitud de las virutas de madera o pulverizarlas, aumentando así el rendimiento de las operaciones de corte.In the previous description it has been shown that the cutting tool according to the present invention achieves the goals and objectives mentioned above; in fact, it has arranged a wood board cutting tool, particularly a spindle mower for mounting on CNC machines, which exceeds drawbacks and limitations of known solutions by the prior art; indeed, the cutting tool before described, thanks to being provided with recesses 10, 11, is capable considerably reduce the length of wood chips or spray them, thus increasing the performance of the operations of cut.

La herramienta de corte con arreglo a la presente invención también mejora considerablemente la expulsión de las virutas de madera de la zona de trabajo y la propia herramienta, gracias al impulso que ejercen en dirección hacia fuera, los rebajes 10, 11, aumentando así la media de vida útil de los filos.The cutting tool according to the The present invention also greatly improves the expulsion of wood chips from the work area and the tool itself, thanks to the impulse exerted in the outward direction, the recess 10, 11, thus increasing the average lifespan of the edges.

Se apreciará fácilmente que la herramienta de corte antes descrita a mero título de ejemplo, puede ser objeto de muchas modificaciones y diversas configuraciones sin por ello apartarse del alcance de la presente invención. Se hace notar también que los materiales utilizados, así como la forma y dimensiones de las piezas individuales que la componen, pueden ser como más convenga a la intención deseada, sin que ello implique apartarse de la sustancia de la presente invención.It will be readily appreciated that the tool court described above by way of example, may be subject to many modifications and various configurations without it depart from the scope of the present invention. It is noted also that the materials used, as well as the shape and dimensions of the individual pieces that compose it, can be as it suits the desired intention, without implying depart from the substance of the present invention.
