Un perfeccionamiento ventajoso está caracterizado porque las piezas aisladas se producen con una anchura variable sobre su eje longitudinal.An advantageous improvement is characterized in that the insulated pieces are produced with a width variable on its longitudinal axis.
A continuación se explica en detalle un ejemplo de ejecución de la invención con base en el dibujo adjunto. En el dibujo muestranAn example is explained in detail below. of execution of the invention based on the attached drawing. At drawing show
la figura 1 dos piezas aisladas con alturas variables sobre su eje longitudinal en una representación en perspectiva,Figure 1 two insulated pieces with heights variables on its longitudinal axis in a representation in perspective,
la figura 2 las piezas aisladas conforme a la figura 1 con aristas interiores cortadas,Figure 2 the insulated parts according to the Figure 1 with cut inside edges,
la figura 3 las piezas aisladas conforme a la figura 2 en estado de unión mutua yFigure 3 the insulated parts according to the figure 2 in a state of mutual union and
la figura 4 secciones transversales a lo largo de las líneas A-A y B-B en la figura 3.Figure 4 cross sections along of lines A-A and B-B in the figure 3.
En la figura 1 se han representado una primera pieza aislada 1 y una segunda pieza aislada 2, estando producidas ambas mediante perfilado por rodillos a partir de una tira de chapa plana rectangular. La primera pieza aislada 1 presenta una sección transversal en forma de Z, que se compone de un primer segmento 3 horizontal inferior, un segmento 4 vertical y un segmento 5 horizontal superior. El segmento 3 horizontal inferior presenta sobre el eje longitudinal de la primera pieza aislada 1 de la misma anchura. El segmento 4 vertical presenta una altura variable sobre el eje longitudinal de la primera pieza aislada 1. La altura del segmento 4 vertical es mínima en los extremos de la primera pieza aislada 1. Aumenta hacia el centro y alcanza en el centro la máxima altura. La altura del segmento 4 vertical sigue un recorrido fundamentalmente en forma de S. En el centro es mayor que en los extremos.In Figure 1, a first insulated piece 1 and a second insulated piece 2, being produced both by roller profiling from a strip of sheet metal rectangular flat The first insulated piece 1 has a section Z-shaped cross section, which consists of a first segment 3 lower horizontal, a vertical segment 4 and a segment 5 upper horizontal. The lower horizontal segment 3 presents on the longitudinal axis of the first insulated piece 1 thereof width. Vertical segment 4 has a variable height above the longitudinal axis of the first insulated piece 1. The height of the vertical segment 4 is minimal at the ends of the first piece isolated 1. Increase to the center and reach the center maximum height. The height of the vertical segment 4 follows a path fundamentally in the form of S. In the center it is greater than in the extremes
Esta configuración es especialmente ventajosa cuando la pieza constructiva sufre un esfuerzo de flexión, ya que el momento de flexión es máximo en el centro de la pieza constructiva y allí la mayor altura de los segmentos verticales se contrapone a la resistencia máxima.This configuration is especially advantageous. when the construction piece undergoes a bending effort, since the bending moment is maximum in the center of the piece constructive and there the greatest height of the vertical segments is opposes the maximum resistance.
Debido a que la altura del segmento 4 vertical de la primera pieza aislada 1 es variable sobre el eje longitudinal de la pieza constructiva, la arista interior 6 no forma en el extremo del segmento 5 horizontal superior ninguna línea recta. En el ejemplo de ejecución se necesita en el centro de la primera pieza aislada 1 más material para el segmento 4 vertical, de tal modo que allí se dispone de menos material para el segmento 5 horizontal superior. La anchura del segmento 5 horizontal superior es por lo tanto menor en el centro de la primera pieza aislada 1 que en los extremos.Because the height of the vertical segment 4 of the first insulated piece 1 is variable on the longitudinal axis of the construction piece, the inside edge 6 does not form in the end of the upper horizontal segment 5 no straight line. In the execution example is needed in the center of the first piece isolated 1 more material for vertical segment 4, so that there is less material available for the horizontal segment 5 higher. The width of the upper horizontal segment 5 is therefore much smaller in the center of the first insulated piece 1 than in the extremes
La segunda pieza aislada 2 es simétrica a la primera pieza aislada 1 y comprende los componentes correspondientes 3', 4', 5' y 6'. Las ejecuciones sobre la primera pieza aislada 1 son válidas de forma correspondiente para la segunda pieza aislada 2.The second isolated piece 2 is symmetrical to the first insulated part 1 and comprises the corresponding components 3 ', 4', 5 'and 6'. The executions on the first isolated piece 1 are valid correspondingly for the second insulated part 2.
Las piezas aisladas 1, 2 se cortan por sus aristas interiores 6, 6'. Como puede verse en la figura 2 las piezas aisladas 1, 2 se cortan por sus aristas interiores 6, 6' en línea recta, de tal modo que se forman aristas de corte 7, 7' rectilíneas que discurren en paralelo al eje longitudinal de las piezas aisladas 1, 2.The insulated pieces 1, 2 are cut by their 6, 6 'inside edges. As you can see in figure 2 the pieces insulated 1, 2 are cut by their inner edges 6, 6 'in line straight, so that straight 7, 7 'cutting edges are formed running parallel to the longitudinal axis of the insulated pieces 1, 2.
A continuación se unen entre sí las piezas aisladas 1, 2 a lo largo de las aristas de corte 7, 7', precisamente soldadas, en especial soldadas por láser. Por medio de esto se forma la pieza constructiva 8 mostrada en la figura 3, que presenta una altura variable sobre su eje longitudinal. La pieza constructiva 8 tiene sobre su eje longitudinal en todas partes la misma anchura, es decir, en todas partes la misma distancia a los segmentos verticales 4, 4'. Sin embargo, también podrían presentar una anchura variable sobre su eje longitudinal (no representada en el dibujo).Then the pieces are joined together isolated 1, 2 along the cutting edges 7, 7 ', precisely welded, especially laser welded. By means of this it form the construction piece 8 shown in figure 3, which presents a variable height on its longitudinal axis. The constructive piece 8 has the same width on its longitudinal axis everywhere, that is, everywhere the same distance to the segments vertical 4, 4 '. However, they could also have a width variable on its longitudinal axis (not represented in the He drew).
Las secciones transversales de la pieza constructiva 8 forman, como puede verse en la figura 4, un perfil de sombrero con segmentos horizontales inferiores 3, 3', segmentos verticales 4, 4' y segmentos horizontales superiores 5, 5', que están unidos entre sí a lo largo de las aristas de corte interiores 7, 7'. En el extremo de la pieza constructiva 8, es decir en el corte A-A, su altura es menor en el centro, precisamente en el corte B-B.The cross sections of the piece constructive 8 form, as can be seen in figure 4, a profile of hat with 3, 3 'lower horizontal segments, segments vertical 4, 4 'and upper horizontal segments 5, 5', which are linked together along the inside cutting edges 7, 7 '. At the end of the construction piece 8, that is in the A-A cut, its height is lower in the center, precisely in the B-B cut.
Mediante la invención se hace posible una variación de la sección transversal en el caso de una pieza constructiva perfilada por rodillos, y precisamente mediante la configuración de dos o más piezas aisladas o segmentos, que presentan en el eje longitudinal una sección transversal variable. Las piezas aisladas 1, 2 pueden perfilarse por rodillos en una instalación. Las piezas aisladas 1, 2 se cortan a continuación. Pueden ensamblarse entre sí para formar una pieza constructiva ensamblada por láser de forma discontinua. Mediante la invención pueden conseguirse todas las ventajas que aporta el procedimiento de moldeado por rodillos frente al procedimiento de prensado, en especial menores costes de herramientas, elevada plastificación residual y tolerancias. El corte de las aristas interiores 6, 6' puede realizarse en línea.By means of the invention a variation of the cross section in the case of a piece construction profiled by rollers, and precisely by means of configuration of two or more isolated pieces or segments, which they have a variable cross section on the longitudinal axis. The insulated pieces 1, 2 can be profiled by rollers in one installation. The insulated pieces 1, 2 are cut next. They can be assembled together to form a constructive piece laser assembled discontinuously. By the invention you can get all the advantages of the procedure of molded by rollers against the pressing procedure, in special lower tool costs, high plasticization residual and tolerances. The cut of the inner edges 6, 6 ' It can be done online.
