    The invention is illustrated with exemplary embodiments and in the accompanying drawings, in which Fig. 1 schematically illustrates the respective stages of an exemplary method according to the invention, and Fig. 2 schematically illustrates the manufacturing plant for carrying out the method according to Fig. 1 top view.
    In the exemplary stage sequence 1 shown in Fig. 1 which carries out the method according to the invention, the essential stages consist of stage 2 for chemical cleaning of the metal prefabricated, stage 3 adhesive application on the surfaces of the cleaned metal prefabricated and stage 4 annealing of the prefabricated.
    Before stage 2 of chemical cleaning, a preliminary control stage 9 is carried out, where the geometry of the metal prefabricated products which are delivered from warehouse 5 is checked in order to eliminate defective prefabricated or prefabricated products with incorrect dimensions. 10 15 20 25 30 4 Initial precursors for stages 3 and 4 are also checked in control stages 10.
    Stage 2 is carried out in an automated dipping plant using automatic conveyor 21, which transports prefabricated products taken from warehouse 5 to the following points where the respective sub-stages in stage 2 of chemical cleaning are carried out, which include degreasing the surface (22), first rinsing (23), activation with an activator for zinc phosphating (24), zinc phosphating (25), second rinsing (26), passivation (27) and drying (28). Each of the sub-stages 22-27 is carried out by dipping the prefabricated product in a suitable agent for a time suitable for the completion of planned reactions, as explained in detail below and with reference to Fig. 2.
    In sub-stage 22, the degreasing takes place using a hot mixture consisting of industrial water, solutions of cleaning concentrate and degreasing concentrate. In the first cold rinse in sub-stage 23, industrial water with ambient temperature is used.
    Activation of the prefabricated surface in sub-stage 24 takes place in a solution of demineralized water and activator for zinc phosphating which maintains ambient temperature.
    Sub-stage 25 of zinc phosphating is carried out by dipping the prefabricated product in a hot solution of demineralized water, zinc phosphating agent and accompanying additives. In sub-stage 26, the second cold rinsing is carried out in demineralized water with ambient temperature. Thereafter, the prefabricated products end up in sub-stage 27 where their surface is passivated using a solution of demineralized water and ambient temperature passivating agent. In lower stage 28, the prefabricated product is dried with hot air.
    In each of the sub-stages 22-27, your different alternative compositions can be used, where examples together with parameters of the respective stages and sub-stages are given with reference to the exemplary manufacturing plant in Fig. 2.
    After completion of stage no. 2 of chemical cleaning, stage 11 is carried out, which relates to protective treatment of the parts of the surfaces of the metal elements which are not to be glue-coated during subsequent process stages by application of protective elements.
    In the next stage 3, the prefabricated products are coated with adhesive in an automated spray box.
    The adhesives are prepared in a separate process No. 6, and residues from stage 3 are further processed in disposal process No. 7.
    In order to achieve a suitable adhesion of the adhesive layer applied in stage 3, the prefabricated products in the last stage no. 4 which takes place in an electric oven are dried and annealed and from there finished elements are sent to layer 8.
    I fi g. Fig. 2 schematically shows the manufacturing plant 12 which performs the above-mentioned stages and illustrated in Fig. 1 for the method according to the invention.
    Raw metal prefabricated products are first transported from warehouses not shown in the drawing to station 121, where their geometry (dimensions) is checked by means of a non-contact optical type scanner. The scanner, by performing appropriate measurements using CAD software, determines whether the elements meet the set measurement requirements, which means that defective and incorrect elements can be discarded.
    Elements which have been approved for the further part of the process are transported to the conveyor 21 of the immersion plant 122. The conveyor 21 has a surface gripping device with the required lifting capacity which lowers a polypropylene basket with the prefabricated products in the vessel 1222-1228 where the sub-stages 22-28 of the chemical pretreatment are performed.
    The first tank 1222 contains a mixture of industrial water, the solutions of the cleaning concentrate (eg concentrate HAKUPUR 50-636 or HAKUPUR 19-69-1 manufactured by Chemische Werke Kluthe GmbH) with a concentration of 7-10% and the degreasing concentrate (eg NETZMITTEL 358-1 Kluthe GmbH) with concentration 0.7-1.0%, with temperatures in the range 65 to 85 ° C. The prefabricates are dipped in tub 1222 for 10 minutes and then fl transferred to tub 1223 containing water at room temperature, where they are rinsed for 1 minute.
    Then the prefabricated products continue to vessel 1224 containing a solution of demineralized water and activator for zinc phosphating (for example ACTIVATOR CT of the brand Kluthe GmbH) with a concentration o.1o-o.15% which is kept at room temperature where they are kept for 1 minute.
    In the next vessel 1225, zinc phosphating of the prefabricated surfaces is carried out in a 10 minute bath containing hot solution of demineralized water, zinc phosphating agent (eg DECORRDAL 306 A made by Kluthe GmbH) with a concentration of 5.0-5.5% and accelerating additives (eg BESCHLEUNIGER 111 Kluthe GmbH) 0.04-o.o5%, the temperature of which is between 65 and 85 ° C.
    In addition, the phosphating solution may contain adjustment solutions such as solutions made by Kluthe GmbH ADDITIV KL (alkaline solution), TONER P (acid solution), TONER Zn (zinc solution), TONER Ni (nickel solution), TONER Mn (manganese solution). After phosphating, the prefabricated products are rinsed for the second time for 1 minute in vessel 1226 containing demineralized water and then the chemical pretreatment is terminated with one minute of passivation in vessel 1227 containing a solution of demineralized water and passivating agent at a concentration of 3.0-8. 0% holding fllmStßmpefâltllf.
    After leaving vessel 1227, the prefabricated products in vessel 1228 are dried for 10-15 minutes with hot air at a temperature between 80 and 100 ° C.
    From the immersion plant 122, the prefabricated products continue to station 123, where surfaces which are not to be coated with glue during future process stages are treated with masking foil or polyethylene tape strips with a thickness of 0.5 to 5.0 mm with an adhesive layer which is made using a punching press with rotating punching head. .
    The protected surface precursors are then transported to two wet spray cans 124, 125, and the protected volume precursors are delivered to rotating spray cans 126.
    The glue mixture is fed to the spray boxes 124-126 from the mixing box 127, where there is a tank that holds about 100 l of glue of the Chemosil type (alternatively glue of the type Thixon, Megum is used), which after bottling is diluted and delivered to the spray boxes with a fate of 20 l / h.
    The surface prefabricated products are coated with glue in two stages: first with a base layer of glue in box 124, and then with a surface layer of glue in box 125, where the temperature of the glue applied in each of the sub-stages is in the range from 30 to 50 ° C. usually from 1 to 10 minutes. Each of the boxes 124, 125 is equipped with an electric motor-driven rotating platform for setting up prefabricated, spraying robots with digitally and manually controlled spray guns with spray pressure in the range from 3 to 4 bar, water curtain fed by a suitable pump and a suction nozzle connected to coagulation glue separator 128 which removes water from the water curtain and residual particles of glue from the box to the separator. The separators 128 separate the water and glue mixture so that you get clean water that can be reused or diverted directly to the drainage system and blocks of glue mud intended for disposal.
    The separators 128 continuously suck up water from the water curtain in the boxes 124, 125 and capture glue particles with a capacity of 80 liters / minute. The volume prefabricated is coated with glue in one stage in a rotating spray box 126, where the prefabricated is painted using a centrally located spray gun with spray pressure in the range from 3 to 4 10 7 bar during simultaneous rotational movement of the box, which allows the glue to be applied to all current surfaces, incl. interior surfaces. The application process of adhesives with temperatures in the range of from 30 to 50 ° C in rotary spray box 126 usually takes from 4 to 10 minutes.
    From the boxes 125, 126, the prefabricated products with applied adhesive layers are transported to an electric furnace 129, where they are annealed at a temperature in the range from 190 to 210 ° C for 30 minutes. After annealing, the prefabricated goods are sent to the finished goods warehouse.
    The transport between the respective stations in the plant 12 can be automatic, semi-automatic or manual and during the transport of the prefabricated goods between the boxes 124 and 125, between the boxes 125, 126 and the oven 129 and after the oven 129 the condition of the coating can be checked automatically or ocularly.
    The manufacturing plant 12 is also ideally equipped with a system, not shown in the drawing, for recording process parameters in order to be able to determine the causes of any defects in the adhesive layer.
