      Blechp [alpha] neel with subsequent anti-corrosion protection and its production catfish  Technical Field The invention solves the enamelled metal sheet  Sheet metal panel in which cuts were made by mechanical processing, whereby the integrity of the enameled coating was injured with subsequent anti-corrosion protection, and method of manufacture thereof.  Previous state of the art The enamelled sheet metal can not be used on the edges, as on the  Surface, be provided with email. Upon hot working of the enamelling or enamelling powder coated sheet, which is based on oven temperature heating at which the enamel sinters and bonds to the metal surface, the sheet edge on which the enamel layer is insufficient is stripped. Therefore, the enameled vessels are provided on the edge with stainless profile, which is pressed onto the edge. In large-scale enamelled sheet-metal panels, which are e.g. form a cladding attached to the construction, must be produced in the enamelled sheet holes, for various reasons. Sometimes a passage for piping, another time the  Noise protection perforation are made, or a part of the sheet metal panel only has to be separated. This mechanical processing can be done by laser, water jet or ordinary mechanical tools. However, the most exposed cut surface is created each time, causing corrosion and damaging the bonding force between the sheet and the enamel layer at the point of mechanical working. Such places are treated with different paintings. Notwithstanding the low productivity of this process because the protective paint is applied by hand, the efficiency of such corrosion protection is low. Substance of the solution  A sheet metal panel with sufficient corrosion treatment according to the invention consists of a sectioned enamelled sheet where the cut sides are provided with a protective coating, most preferably on the basis of zinc, or with an electrocoated Lgck. The gglvgnic coating, as well as the lacquer applied by means of electrophoresis, ensure sufficient corrosion protection on the cut sides by processing the bared cut surface in the produced cuts, without the coating thus applied adhering to the enamelled surface.  In another embodiment, the sheet metal panel is made of enamelled sheet, which is connected by adhesive connection with a stiffening plate in which the averages are configured identical to the cuts. The average pages are also provided with a protective cover. The manufactured in such a manner panel is characterized by greater rigidity and the protective coating on the cut walls ensures sufficient corrosion protection of the cut walls in the enamelled sheet metal and the average walls in the stiffening plate and possibly in the outer surface of the stiffening plate. On the enamelled surface of the enamelled sheet, the protective coating will not adhere.  The manner in which the sheet metal panel is made by processing the cuts eliminates the above-mentioned drawbacks and is characterized by high productivity and reliability of corrosion protection of the cut-bare metal. The mechanically processed enameled sheet, in which e.g. By means of laser or cutting tool the cuts have been made, in the form of perforations or by mere division, is provided on the cuts with protective coating. This means that both types of application of the protective coating, whether formed by electroplating or by electrophoresis, result in the properties of the ion movements in the electrolyte. In the first case, the electrolyte consists of a galvanic bath and the second of a paint bath.   By forming an electric field between the cathode and the anode, the metal ions or paint particles are merely applied to the metal surface. Such a surface consists for the time being of the cut walls in the enamelled sheet. On an enamelled surface of the protective coating does not stick because the enamel is an insulating material.  If the cuts are on the edge of the enamelled sheet, it is sufficient to immerse at least the cut portion in a plating bath and coat it with metal in the usual way. Similarly, one proceeds, if one wants to provide the cuts with protective coating formed by lacquer. With regard to the conductivity of the metal part of the enamelled sheet and non-conductivity of the enamel of the galvanic coating, as well as the paint in the painting of electrophoretic Lackierwerkstätte, only on the cut in the metal part of the enameled sheet and guf squares where the Emoilschicht possibly during mechanical Begrbeitung was damaged, eg to cling as jumping. Thereafter, the sheet metal panel is removed from the bath and processed by ordinary procedure.   When galvanizing by rinsing and the electrophoretic painting, it is still possibly created by burnout, according to the type of paint used.  Description of the picture in the drawing  The overall view of the sheet metal panel is shown in Fig. 1, the detail AA through the sheet metal panel formed only of enamelled sheet is shown in Fig. 2 and the detail section through the formed of enameled sheet metal, which is connected to stiffening sheet metal panel is on Fig. 3 shown. Description of the exemplary implementation of the invention  Dgs sheet metal peg consists of the cast sheet metal 1, in which the cuts are gauged. In the upper part of the peg, the cuts forming the perforations of the covert protection are ü. In the lower part of the passage 12 of the air-conditioning channel enabling section 12. The sides of the cuts 12 are provided with a protective coating 2, which consists of a galvanic coating, preferably on the basis of zinc or applied by electrophoresis paint. In order to increase the rigidity of the sheet metal panel, the enameled sheet 1 is connected by means of the adhesive connection 3 with the stiffening sheet. in the stiffening plate 4, the averages are identical to the cuts ü, V2 formed. The adhesive compound 3 is formed in this case by means of two-component adhesive.  example 1  The enamelled metal sheet, the part of which was separated by laser, produced sheet metal panel is made with the part formed by the cut in a  Electroplating solution immersed in the galvanizing and on the cut is applied by galvanizing a zinc layer. Thereafter, the sheet metal panel is rinsed with water.  Example 2 The sheet-metal panel made of enamelled sheet metal joined to a stiffening sheet with adhesive bonding is provided on the whole surface with the cuts producing the perforation of the acoustic protection formed with mechanical reamer same as the apertures drilled in the stiffening sheet. The entire sheet metal panel is dipped into the painting bath of the electrophoresis paint shop and provided with the protective coating on the cuts and on the metal walls of the stiffening sheet. Subsequently, the sheet metal panel is rinsed with water and possibly burned to the required temperature, the paint used.
