    Procedure for obtaining a high resistance composite panel and panel obtained. The invention focuses on the fact of obtaining a high strength composite panel based on two extreme sheets of aluminum or galvanized and stainless steel and a core also of aluminum or galvanized and stainless steel with a structure that makes it much cheaper than conventional panels with core in honeycomb and, in addition, allows continuous production, which makes the product can be cut to different sizes with a single installation optimizing its efficiency. The panel that is obtained will have a core (5) with a buttoned structure, in which a matrix of elements is defined, distributed in a quincunx of essentially frustoconical configuration, with a slightly curved generatrix, which ensures a high resistance in all directions, against of what happens in the most economical existing panels that have a corrugated profile core and that do not support well determined horizontal efforts.

    PROCEDURE FOR OBTAINING A HIGH RESISTANCE COMPOSITE PANEL, INSTALLATION AND PANEL OBTAINED
    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION
    The present invention relates to a process for obtaining a composite panel of high strength, manufactured in continuous, thus obtaining high versatility for the same installation when obtaining panels of different dimensions depending on the specific needs of each case .
    It is also the object of the invention to provide a composite panel of high strength and reduced cost, with high fire resistance.
    The invention is within the scope of the industry of composite panels of high strength preferably obtained based on aluminum, although other metals or alloys would be equally applicable without affecting the essence of the invention.
    BACKGROUND OF THE INVENTION
    In the practical scope of the invention, high strength aluminum-based panels are known, in which a central core and two end layers are defined, embodied in two aluminum sheets that are fixed by adhesive to said central core, also obtained in aluminum and which is embodied in a honeycomb structure that allows to increase the thickness of the panel, giving it great strength, without significantly increasing its weight.
    Although this type of panels satisfactorily fulfill the function for which they have been provided, the reality is that the process of manufacturing them is extremely expensive, so that when they are intended to cover large surfaces, such as
    5

    30
    They can be facades of buildings and the like, this problem of cost is increased with the negative impact that this implies.
    Trying to obviate this problem, in invention patents EP 0939176 and EP 2993037, sandwich aluminum panels are described much cheaper to obtain, in which a pair of extreme sheets is defined, among which a core based on a wavy profile, whether of sine, trapezoidal, triangular or quadrangular configuration that is fixed to said sheets by means of adhesive.
    While this type of panels withstand the efforts in the main direction for which they have been planned very well, that is, to support the vertical forces, they have a great directionality, that is, they do not support other efforts in other directions as well, such as horizontal and perpendicular efforts to the direction in which the wavy profile is prolonged.
    To a greater extent, this type of panels are manufactured to measure, so that the extreme sheets and the core are manufactured separately, are cut to size and finally joined by adhesive, which complicates the installation when it is intended to obtain very large panels different sizes.
    DESCRIPTION OF THE INVENTION
    The procedure that is recommended resolves in a fully satisfactory way the problem previously exposed in each and every one of the aspects mentioned, allowing to obtain an economic panel, highly resistant in any direction and that is manufactured in continuous, being able to be cut to the extent that want in the final process of obtaining it, which significantly simplifies the installation, in addition to giving it a high versatility.
    To do this, and more specifically, the process starts with an aluminum alloy and quench coil suitable for drawing with isotropy to obtain the core

    of the panel, which is assisted by a rewinder and a feeder that continuously feeds a press in which two male and female tools are established that generate on the aluminum plate a buttoned array of small embuticiones of configuration essentially in cone trunk, with its slightly curved generatrix, conveniently distributed to the tresbolillo, in order to optimize the resistance of the panel to obtain in all directions.
    The core after exiting the press is passed through an adhesive application station both on its lower face and on its upper face.
    Said station can be materialized in two possible ways. In a first variant embodiment, the station has a kind of rollers on which the adhesive is applied in a liquid state, so that said rollers come into contact exclusively with the end surfaces defined in the upper face and the lower face of the core after its exit from the press, minimizing the use of adhesive, and consequently increasing the fire resistance of the final panel obtained.
    In a second variant embodiment, the adhesive is applied directly over the entire upper and lower surface of the core, through respective heated rollers, and by adhesive sheets that are fed through coils and that are heated by infrared emitters.
    In any case, once the adhesive has been applied on both sides of the core, there are previously treated aluminum sheets on it to improve the
    anchoring of the adhesive, which will constitute the extreme layers of the panel, which are applied
    also in continuous, from respective coils and applicator cylinders, so that their internal face comes into contact with the adhesive areas of the core, passing the assembly through an oven through which the curing of the
    adhesive and therefore the perfect fixation of the extreme sheets to the core,
    establishing at the exit of said furnace a pressing and traction mechanism that allows continuous feeding to a shear, in which finally, the set obtained is cut to the extent that is required at each moment, without having to make changes in the installation, being the panels obtained redirected through a

    Conveyor belt to the corresponding stacker for packaging.
    In this way, a high-strength composite panel is obtained, based on two extreme aluminum sheets and an equally aluminum core with a buttoned structure, in which a matrix of elements distributed to the three-pin and essentially conical trunk configuration is defined , of a slightly curved generatrix that, given this configuration allows to resist great efforts in all directions, contrary to what happens in conventional low-cost panels and, on the contrary, presents much lower manufacturing costs than core panels in honeycomb previously analyzed.
    Although the procedure and consequently the panel obtained has been described based on the use of aluminum sheets to obtain both the outer layers of the panel and its core, this process could also be carried out based on galvanized and stainless steel sheets either for one or more of the layers that participate in it, that is, that a panel could be obtained in which its three layers were made of steel, or intermediate combinations depending on the material used for each layer, without affecting it The essence of the invention.

    To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

    PREFERRED EMBODIMENT OF THE INVENTION
    In view of the aforementioned figures, and in particular of figure 1, it can be seen how the installation of the invention starts from an aluminum alloy and quench coil suitable for drawing with isotropy from which the panel core with a thickness between 0.2 and 0.3 mm, associated with the corresponding unwinder (1), and through a feeder (2) passes the sheet of aluminum or galvanized and stainless steel through a press (3 ), in which a complementary male (4) and a complementary female (4 ') tool are established, which generate on the plate a buttoned array of small embossments of essentially cone-shaped configuration, with its slightly curved generatrix, conveniently distributed to the Tresbolillo, defining a depth for these embossments between 3 and 8 mm, with its largest base having a diameter between 8 and 12 mm and its smaller base with a diameter between 4 and 6mm.
    For its part, the press will have a useful width of between 1600 and 1700 mm, with an adjustable feed rate, of the order of 10 to 26 m / min.
    The core (5) after exiting the press (3) is passed through an adhesive application station (6) both its lower face and its upper face.
    Said station (6) can be materialized in two possible ways.
    In a first variant embodiment, the station (6 ') has a kind of rollers (7) on which the adhesive is applied in a liquid state, so that said rollers (7) come into contact exclusively with the end surfaces ( 5 ') defined on the upper face and the lower face of the core (5) after its exit from the press, minimizing the use of adhesive, and consequently increasing the fire resistance of the final panel obtained, rollers (7) to the that the two-component polyurethane type adhesive is applied by means of cuvettes (9) in which a few second rollers are partially submerged

    (8), which in turn come into contact with the surface of the rollers (7).
    In a second variant embodiment, the station (6 '') consists of two unwinders of a polymeric adhesive film (10) that is heated by infrared emitters (11) and applied on the surface of the core (5) by heated rollers (12) through internal oil circuits.
    After the adhesive application station (6), two applicator cylinders (13) of the aluminum sheets (14) and (15) or galvanized and stainless steel are established, which will constitute the end layers of the final panel to be obtained. which can be of the same or different thickness, these being arranged on the previously adhesive faces of the core (5).
    The three-layer structure thus described is passed, also in continuous, through an oven (16), with a work surface of the order of 4 to 6 meters, applying a temperature between 65 and 70 ° C for the whole case of the adhesive liquid, and between 170 and 180 ° C for the case of film adhesive.
    This process causes the three layers of the panel to be tightly fixed to each other, establishing at the exit of said furnace (16) a pressing and traction mechanism (17) that allows to continuously feed a movable shear (18), from which the panels are cut to the extent that is required at all times, without having to make changes in the installation, being the panels obtained redirected through a conveyor belt (19) to the corresponding stacker (20) for its packaging and distribution.
    In this way, and in accordance with Figure 2, a high-strength composite panel is achieved, based on two aluminum end plates (14-15) and an aluminum core (5) with a buttoned structure, in the one that defines a matrix of elements distributed to the tresbolillo and of essentially conical trunk configuration, of slightly curved generatrix of high resistance and reduced cost.
