Description

"PORTAUTILES DE PUNZONAR" CAMPO DE LA INVENCIÓN "PORTAUTILES DE PUNZONAR" FIELD OF THE INVENTION
Esta invención se refiere a un dispositivo destinado a sujetar las matrices y punzones en las partes inferior y superior de un troquel de punzonar, como los empleados para fabricar piezas de vehículos y similares.This invention relates to a device intended to hold the dies and punches in the lower and upper parts of a punching die, such as those used to manufacture vehicle parts and the like.
ESTADO DE LA TÉCNICA ANTERIOR En Ia fabricación de componentes de vehículos y similares, por ejemplo una pieza de chapa interior o exterior, primero se obtiene Ia forma de Ia pieza por estampación y luego se procede a punzonar los lugares en que han de fijarse otros componentes, siendo muy habitual que en una de estas piezas estampadas hayan de utilizarse del orden de veinte parejas de matrices y punzones, que operan en distintos lugares de Ia misma. Estas operaciones de punzonado requieren una extremada precisión, siendo muy habitual que una o varias de las parejas de matrices y punzones hayan de ser modificadas en su posición por errores del plano originario o por variaciones planteadas por el cliente con posterioridad a dicho plano. En Ia actualidad los porta-útiles empleados constan de una sola pieza de soporte que, tras instalarle Ia matriz o el punzón, es amarrada a Ia parte inferior o superior del troquel en una posición que viene determinada con precisión por un par de pasadores de posicionamiento que tienen su alojamiento en dichas partes del troquel; los tornillos de amarre guardan una pequeña holgura respecto de su agujero en Ia pieza de soporte.STATE OF THE PREVIOUS TECHNIQUE In the manufacture of vehicle components and the like, for example a piece of inner or outer sheet, first the shape of the piece is obtained by stamping and then the places where other components are to be fixed are punched. , being very habitual that in one of these stamped pieces they have to be used of the order of twenty pairs of matrices and punches, that operate in different places of the same. These punching operations require extreme precision, being very common that one or more of the pairs of dies and punches have to be modified in their position due to errors in the original plane or by variations raised by the customer after that plane. At present, the tool holders used consist of a single support piece that, after installing the die or the punch, is tied to the lower or upper part of the die in a position that is precisely determined by a pair of positioning pins that have their accommodation in said parts of the die; The tie screws keep a small clearance with respect to their hole in the support piece.
Cualquier modificación posicional del porta-útiles exige que sea desmontado para encasquillar si es una matriz encastrada en Ia parte inferior y los alojamientos de los pasadores de posicionamiento y hacer unos nuevos en Ia posición correcta si es en Ia parte superior (porta punzón). Para ello, una vez desmontado el porta-útiles, hay que desmontar las partes de un troquel, que pesan entre tres y quince toneladas, trasladarlas a Ia máquina- herramienta, mecanizar Ia nueva disposición y volver a montarlas en el troquel de punzonar; todo Io cual puede suponer quince horas de trabajo, además del perjuicio propio de Ia parada de producción; cuando Ia diferencia de posición a corregir es más pequeña que Ia holgura entre los tornillos de amarre y su agujero en el soporte de Ia matriz o punzón es posible que sea suficiente con arreglar Ia posición de los pasadores de posicionamiento y jugar con Ia holgura de los tornillos de amarre para solucionar el problema; sin embargo, si Ia variación requerida es mayor será necesario taponar también los taladros roscados para los tornillos de amarre y hacer otros para Ia nueva posición. EXPLICACIÓN DE LA INVENCIÓN Y VENTAJASAny positional modification of the tool holder requires that it be disassembled if it is a matrix embedded in the lower part and the positioning pin housings and make new ones in the correct position if it is in the upper part (punch holder). To do this, once the tool holder has been disassembled, the parts of a die, weighing between three and fifteen tons, must be removed, transferred to the machine tool, machined in the new arrangement and reassembled in the punching die; all of which can be fifteen working hours, in addition to the damage of the production stop; when the position difference to be corrected is smaller than the clearance between the tie screws and its hole in the support of the die or punch, it may be sufficient to fix the position of the positioning pins and play with the clearance of the tie down screws to solve the problem; However, if the required variation is greater, it will also be necessary to plug the threaded holes for the tie screws and make others for the new position. EXPLANATION OF THE INVENTION AND ADVANTAGES
Frente a este estado de cosas, Ia presente invención tiene por objeto un porta-útiles de punzonar que consta de un armazón fijo, que posee los medios de tornillos de amarre y de pasadores de posicionamiento con relación a Ia respectiva parte inferior o a Ia parte superior del troquel punzonador, un soporte móvil que está acoplado en el armazón fijo, y unas primeras galgas calibradas y unas segundas galgas calibradas que de manera conveniente están intercaladas entre el armazón fijo y el soporte móvil; cuyo armazón fijo consta de un cuerpo y una placa-base que está unida al cuerpo y adosada a las partes inferior o superior de un troquel, en el plano de unión a Ia placa-base el cuerpo forma un canal de paredes rectas a escuadra que se extiende entre dos puntos opuestos de su periferia y que está comunicado con Ia cara frontal del cuerpo a través de un agujero central cuadrado o rectangular que enrasa con las paredes laterales del canal; cuyo soporte móvil forma un patín inferior que su grosor está calibrado a Ia profundidad de este canal y que su anchura está holgada respecto de Ia del canal, en cuyo patín inferior emerge un saliente prismático que su sección es semejante y holgada respecto de Ia del agujero central y que su altura es igual a Ia de este agujero central, cuyo saliente prismático tiene un hueco axial receptor de una matriz o de un punzón, y cuyas primeras galgas calibradas y segundas galgas calibradas están encajadas entre el saliente prismático y el agujero central son transversales al patín inferior y se extienden a todo Io alto del saliente prismático, y las segundas galgas calibradas son longitudinales al patín inferior y se extienden en toda Ia altura de los laterales del soporte móvil abarcando adosadas el grosor del patín inferior más Ia altura del saliente prismático. Frente al tradicional concepto de soporte porta-útil hecho de una pieza, esta constitución propuesta presenta un soporte de varias piezas, de manera tal que Ia pieza de patín y saliente prismático en que va montada Ia matriz o el punzón es susceptible de ser desplazada respecto del armazón fijo jugando con el grosor de las galgas calibradas; como los pasadores posicionadores y los tornillos de amarre están asociados al armazón fijo, toda modificación de posición de Ia pareja matriz-punzón que esté comprendida en los márgenes de las galgas calibradas podrá solucionarse con sólo variar el grosor de las mismas; por Io tanto, bastará con soltar del troquel el armazón fijo, ajustar el juego de galgas calibradas para Ia nueva posición y volver a montarlo en el troquel, evitando tener que desmontar las partes de un troquel, llevarlas a mecanizar, mecanizarlas y volver a montarlas en Ia máquina; en definitiva, Io que antes suponía quince horas de trabajo y parada, ahora puede llevarse a cabo en una hora y con unos medios que no resultan mucho más caros comparativamente con los hasta ahora empleados.Faced with this state of affairs, the present invention aims at a punching tool holder consisting of a fixed frame, which has the means of mooring screws and positioning pins in relation to the respective lower part or the upper part of the punching die, a movable support that is coupled in the fixed frame, and a first calibrated gauges and a second calibrated gauges that are conveniently intercalated between the fixed framework and the movable support; whose fixed frame consists of a body and a base plate that is attached to the body and attached to the lower or upper parts of a die, in the plane of attachment to the base plate the body forms a channel of straight squared walls that it extends between two opposite points of its periphery and that is communicated with the front face of the body through a square or rectangular central hole that flush with the side walls of the channel; whose mobile support forms a lower skate that its thickness is calibrated to the depth of this channel and that its width is loose with respect to that of the channel, in whose lower skate a prismatic projection emerges that its section is similar and loose with respect to that of the hole central and that its height is equal to that of this central hole, whose prismatic projection has an axial hollow receiving a die or a punch, and whose first calibrated gauges and second calibrated gauges are fitted between the prismatic projection and the central hole are transverse to the bottom skate and extend all the way up the prismatic projection, and the second Calibrated gauges are longitudinal to the lower skate and extend along the entire height of the sides of the mobile support, including the thickness of the lower skate plus the height of the prismatic projection. Faced with the traditional concept of a support holder made of one piece, this proposed constitution has a support of several pieces, so that the piece of skate and prismatic projection on which the die or the punch is mounted is capable of being displaced with respect to of the fixed frame playing with the thickness of the calibrated gauges; As the positioning pins and the mooring screws are associated with the fixed frame, any modification of the position of the die-punch couple that falls within the margins of the calibrated gauges can be solved by simply varying their thickness; therefore, it will be enough to release the fixed frame from the die, adjust the set of gauges calibrated for the new position and reassemble it in the die, avoiding having to disassemble the parts of a die, take them to mechanise, mechanize them and reassemble them in the machine; In short, what was previously fifteen hours of work and stop, can now be carried out in one hour and with means that are not much more expensive compared to those used up to now.
Otras particularidades de Ia invención, están referidas a las galgas calibradas; una de ellas es que, para asegurar el mantenimiento de su correcta posición, las primeras y las segundas galgas calibradas tienen sendos orificios por los que está atravesada Ia punta de un tornillo prisionero dispuesto en un agujero roscado practicado en el lateral del cuerpo del armazón fijo; otra de ellas consiste en que las segundas galgas calibradas son tan largas como el lado del agujero central sobre el que están aplicadas, y las segundas galgas calibradas están encajadas entre las primeras galgas calibradas. En cuanto al montaje de Ia placa- base en las partes de un troquel, una ejecución de Ia invención consiste en que Ia placa-base tiene un alojamiento en Ia parte inferior del troquel, mientras que esta placa-base está adosada sobre Ia parte superior del troquel. En otro orden de cosas, para evacuar el material eliminado en el punzonado Ia placa-base tiene una perforación de desahogo que está alineada con el hueco axial del saliente prismático y es de mayor tamaño que el alma de Ia matriz eventualmente instalada en este hueco axial.Other peculiarities of the invention are related to calibrated gauges; One of them is that, in order to ensure the maintenance of its correct position, the first and second calibrated gauges have two holes through which the tip of a captive screw arranged in a threaded hole in the side of the body of the fixed frame is pierced. ; Another of these is that the second calibrated gauges are as long as the side of the central hole on which they are applied, and the second calibrated gauges are fitted between the first calibrated gauges. As for the assembly of the base plate in the parts of a die, an embodiment of the invention consists in that the base plate has a housing in the lower part of the die, while this base plate is attached on the upper part of the die. In another order of things, in order to evacuate the material removed in the punching, the base plate has a relief perforation that is aligned with the axial hollow of the prismatic projection and is larger than the core of the matrix eventually installed in this axial hollow. .
Otro objeto de Ia invención es un elemento de seguridad que está destinado a mantener las galgas calibradas inmóviles, en particular cuando el porta-útiles está en Ia parte superior del troquel; consiste en una chapa de seguridad dotada de una ventana que es menor que el perímetro del saliente prismático y mayor que Ia boca del hueco axial del mismo, cuya chapa de seguridad tiene taladros para su amarre al frente del armazón fijo.Another object of the invention is a security element that is intended to keep calibrated gauges still, in particular when the tool holder is in the upper part of the die; It consists of a safety plate equipped with a window that is smaller than the perimeter of the prismatic projection and larger than the mouth of the axial hollow thereof, whose safety plate has holes for its mooring in front of the fixed frame.

Ia profundidad de este canal (1c) y que su anchura está holgada respecto de Ia del canal (1c), en cuyo patín inferior (2a) emerge un saliente prismático (2b) que su sección es semejante y holgada respecto de Ia del agujero central (1b) y que su altura es igual a Ia de este agujero central (1b), cuyo saliente prismático (2b) tiene un hueco axial (2c) receptor de una matriz (8) o de un punzón (9), y cuyas primeras galgas calibradas (3) y segundas galgas calibradas (4) están encajadas entre el saliente prismático (2b) y el agujero central (1d) de manera que las primeras galgas calibradas (3) son transversales al patín inferior (2a) y se extienden (figuras 7 y 8) a todo Io alto del saliente prismático (2b), y las segundas galgas calibradas (4) son (figuras 6 y 9) longitudinales al patín inferior (2a) y se extienden en toda Ia altura de los laterales del soporte móvil (2) abarcando el grosor del patín inferior (2a) más Ia altura del saliente prismático (2b).The depth of this channel (1c) and that its width is loose with respect to that of the channel (1c), in whose lower skate (2a) a prismatic projection (2b) emerges that its section is similar and loose with respect to that of the central hole (1b) and that its height is equal to that of this central hole (1b), whose prismatic projection (2b) has a axial hole (2c) receiver of a die (8) or a punch (9), and whose first calibrated gauges (3) and second calibrated gauges (4) are fitted between the prismatic projection (2b) and the central hole (1d ) so that the first calibrated gauges (3) are transverse to the bottom skate (2a) and extend (figures 7 and 8) to the entire height of the prismatic projection (2b), and the second calibrated gauges (4) are (figures 6 and 9) longitudinal to the lower skate (2a) and extend along the entire height of the sides of the mobile support (2) covering the thickness of the lower skate (2a) plus the height of the prismatic projection (2b).
El empleo del porta-útiles propugnado es ilustrado mediante Ia figura 2, donde se muestran instalada una unidad en Ia parte inferior (12) y otra en Ia parte superior (13) del troquel; con Ia particularidad de que está previsto que el armazón (1) por Ia placa- base (1b) se monta en un alojamiento (12a) en Ia parte inferior (12) del troquel y provisto de un conducto de desahogo (12b) enfrentado a Ia perforación de desahogo (1f) de Ia placa base (1b), estando previsto que el armazón (1) por Ia placa-base (1b) se monte adosado sobre Ia parte superior (13) del troquel. Las figuras citadas, junto con los detalles mostrados en las figuras 3 á 7, son muy clarificadoras no sólo de Ia constitución del porta-útiles, sino también de su funcionalidad. A este respecto, hay que significar cómo Ia solución propuesta ha independizado los medios de sujeción y posicionamiento en las partes inferior (12) y superior (13) del punzón, con relación a los medios que sustentan Ia matriz (8) o el punzón (9); de tal manera que existe una capacidad de desplazamiento de estos segundos medios respecto de los de amarre y posicionamiento en las partes (12, 13) del troquel, capacidad que es empleada a conveniencia mediante Ia elección de los grosores de las primeras galgas calibradas (3) y las segundas galgas calibradas (4) que han de ser colocadas en el contorno del saliente prismático (2b) respecto del agujero central (1d) del cuerpo (1a) del armazón fijo (1 ); Io que significa que toda variación posicional que esté dentro de los márgenes de esta capacidad de desplazamiento podrá ser solucionada sin variar Ia posición de los tornillos de amarre (10) ni de los pasadores de posicionamiento (11), sólo jugando con Ia selección de las galgas calibradas (3, 4) para situar el eje de Ia matriz (8) y del punzón (9) en Ia nueva posición. Con ello se evita tener que desmontar las partes inferior (12) y superior (13) del troquel, encasquillar los orificios que inválidos, mecanizar nuevos orificios para los tornillos de amarre (10) y los pasadores de posicionamiento (11), y volver a montar las partes (12, 13) del troquel. La solución explicada puede ser empleada para cada una de las parejas de matriz (8) y punzón (9) de las partes (12, 13) de un troquel o sólo para aquellos puestos en que se prevé que se presuma susceptible de tener que ser modificado.The use of the proposed tool holder is illustrated by Figure 2, where a unit is shown installed in the lower part (12) and another in the upper part (13) of the die; with the particularity that it is provided that the frame (1) by the base plate (1b) is mounted in a housing (12a) in the lower part (12) of the die and provided with a relief conduit (12b) facing The relief perforation (1f) of the base plate (1b), being provided that the frame (1) by the base plate (1b) is mounted attached to the upper part (13) of the die. The cited figures, together with the details shown in Figures 3 to 7, are very clarifying not only of the constitution of the tool holder, but also of its functionality. In this regard, it must be understood how the proposed solution has made the clamping and positioning means independent in the lower (12) and upper (13) parts of the punch, in relation to the means that support the die (8) or the punch ( 9); in such a way that there is a capacity of displacement of these second means with respect to those of mooring and positioning in the parts (12, 13) of the die, capacity that is used conveniently by choosing the thicknesses of the first calibrated gauges (3 ) and the second calibrated gauges (4) to be placed in the contour of the prismatic projection (2b) with respect to the central hole (1d) of the body (1a) of the fixed frame (1); Which means that any positional variation that is within the margins of this displacement capacity can be solved without varying the position of the mooring screws (10) or the positioning pins (11), only playing with the selection of the calibrated gauges (3, 4) to position the axis of the die (8) and the punch (9) in The new position. This avoids having to disassemble the lower (12) and upper (13) parts of the die, insert the holes that are invalid, machine new holes for the clamping screws (10) and the positioning pins (11), and return to assemble the parts (12, 13) of the die. The solution explained can be used for each of the pairs of die (8) and punch (9) of the parts (12, 13) of a die or only for those positions where it is expected to be presumed to have to be modified.
De acuerdo con Ia invención, las primeras galgas calibradas (3) y las segundas galgas calibradas (4) (figuras 8 y 9) son de espesores necesarios para realizar Ia regulación, unitaria o complementadamente y tienen sendos orificios (5) por los que está atravesada (figuras 6 y 7) Ia punta de un tornillo prisionero (6) dispuesto en un agujero roscado (1e) practicado en el lateral del cuerpo (1a) del armazón fijo (1); también resulta que las segundas galgas calibradas (4) son (figura 6) tan largas como el lado del agujero central (1d) sobre el que están aplicadas, y las segundas galgas calibradas (4) (figurai) en su largura están encajadas entre las primeras galgas calibradas (3)In accordance with the invention, the first calibrated gauges (3) and the second calibrated gauges (4) (figures 8 and 9) are of necessary thicknesses to perform the regulation, unitary or complementary and have two holes (5) by which it is crossed (figures 6 and 7) the tip of a captive screw (6) disposed in a threaded hole (1e) made in the side of the body (1a) of the fixed frame (1); it also turns out that the second calibrated gauges (4) are (figure 6) as long as the side of the central hole (1d) on which they are applied, and the second calibrated gauges (4) (figurai) in their length are fitted between the first gauges calibrated (3)
Así por ejemplo, con Ia previsión de galgas calibradas (3 y 4) de espesores de tres, dos, uno y medio milímetro y empleando una o varias adosadas para conseguir Ia medida deseada podemos tener rangos de corrección de tres milímetros en cada una de las direcciones con escalones de medio milímetro.Thus, for example, with the forecast of calibrated gauges (3 and 4) of thicknesses of three, two, one and a half millimeters and using one or several townhouses to achieve the desired measurement we can have correction ranges of three millimeters in each of the directions with steps of half a millimeter.
Para Ia evacuación del material cortado en el punzonado, Ia placa-base (1b) tiene (figuras 6 y 7) una perforación de desahogo (1f) que está alineada con el hueco axial (2c) del saliente prismático (2b) y es de mayor tamaño que el alma de Ia matriz (8) eventualmente instalada en este hueco axial (2c).For the evacuation of the material cut in the punching, the base plate (1b) has (figures 6 and 7) a relief perforation (1f) that is aligned with the axial hollow (2c) of the prismatic projection (2b) and is of larger than the core of the die (8) eventually installed in this axial hole (2c).
Para sujetar desde el frente las primeras galgas calibradas (3) y las segundas galgas calibradas (4) existe (figura 10) una chapa de seguridad (7) dotada de una ventana (7a) que es menor que el perímetro del saliente prismático (2b) y mayor que Ia boca del hueco axial (2c) del mismo, cuya chapa de seguridad (7) tiene taladros (7b) para su amarre al frente del armazón fijo (1). Este elemento será empleado de manera preferente para cuando el porta-útiles preconizado vaya instalado en Ia parte superior (13) del troquel.To hold from the front the first calibrated gauges (3) and the second calibrated gauges (4) there is (figure 10) a sheet of safety (7) with a window (7a) that is smaller than the perimeter of the prismatic projection (2b) and greater than the mouth of the axial recess (2c) thereof, whose safety plate (7) has holes (7b) for its mooring in front of the fixed frame (1). This element will be used preferentially when the recommended tool holder is installed in the upper part (13) of the die.
Está previsto que Ia sección en planta del porta-útiles sea circular, rectangular o mixta, así como que pueda incluir en un mismo armazón fijo (1) mas de un soporte móvil (2), por simple repetición adosada del dispositivo.It is envisaged that the plan section of the tool holder be circular, rectangular or mixed, as well as that it may include in the same fixed frame (1) more than one mobile support (2), by simple attached repetition of the device.
