Definitions
- the invention relates to a method for forming sheet metal, in particular for warm or hot forming of blanks, in a forming tool, one or more reinforcement boards being applied to a base plate for partial reinforcement and the base plate and the at least one reinforcement plate being formed together.
- Such methods are known in the prior art, in particular in the production of molded parts for vehicles.
- vehicle sector in particular there is a fundamental requirement to design parts that are as lightweight as possible in terms of weight. This can reduce the vehicle's fuel consumption and significantly improve its manageability and driving properties.
- good stability of the vehicle parts is to be ensured, especially crash stability.
- molded parts such as vehicle spars, which are partially highly stressed in such a crash, it is known to provide these locations which are subject to greater stress locally.
- Such local reinforcement can be achieved by enlarging the cross section, for example by doubling up metal sheets.
- the base plate and the reinforcement plate were each deep-drawn on their own and then joined together to form a complete structural part.
- DE 4307563 C2 therefore suggests, in the area of deep-drawing of sheet metal, that the base sheet and the reinforcing sheet are deep-drawn or stamped together.
- the reinforcing sheet or sheets are attached to the base sheet before the common deep-drawing or die-cutting and after the deep-drawing or die-cutting are non-detachably connected to the base sheet.
- This publication also discloses the provision of corrosion protection measures in the area of the sheets lying one on top of the other. For this purpose, the provision of coated or galvanized steel sheets or the interposition of a plastic or metal foil or an adhesive layer (see also DE 10120121 AI) is mentioned.
- the patched composite sheet is heated to a temperature above the forming temperature of the material of the sheet, formed into the desired shape in the warm state and then held in the closed state with mechanical fixation in the forming state Forming tool and / or fixing and trimming tool cooled in a defined manner.
- a method similar to DE 10049660 AI also discloses DE 10136433 AI.
- a local high reinforcement and increase in rigidity with low additional weight is achieved in a sandwich structure made of base plate and reinforcing plate by inserting a molded body made of glass or a glass mat between these two plates.
- Forming is then carried out in accordance with DE 10049660 AI by hot forming of the entire patched composite sheet, initially heating again to temperatures above the forming temperature of the materials of the sheet, then the composite is placed in a forming tool in the hot state, shaped into the desired shape and mechanically Fixation of the desired forming condition is cooled.
- the edge of the reinforcement plate is connected to the base plate around the glass intermediate element, thereby creating a cavity for the glass intermediate element.
- the present invention is based on the object of providing a method for hot-forming sheet metal or blanks which does not have the disadvantages mentioned above and which enables the production of molded parts in lightweight construction with reinforcement provided for a partially higher load, the compared to the above prior art Technology an even more effective corrosion protection in connection with a secure connection of the main board and the reinforcing board (s) should be possible.
- the object is achieved for a method according to the preamble of claim 1 in that the base board and the at least one reinforcement board are fixed to one another and / or aligned with one another by suitable means and the base board and the at least one reinforcement board are separated after the forming, with at least one connecting layer provided and reassembled.
- the object is also achieved by a structural part which is produced by a method according to the invention. Further developments of the invention are defined in the dependent claims.
- connection layer between the molded parts and thus ensure an optimal connection and sealing of the molded base board and molded or molded reinforcement board (s). Since that
- connection layer is arbitrary.
- a sealing and moisture-repellent foam adhesive layer material film, in particular pressure-sensitive adhesive film, mat, in particular adhesive fiber composite mat, etc. can also be used.
- the connecting layer is preferably formed from a multicomponent adhesive, the components of which are applied to the surface of the motherboard and the at least one reinforcing board or the surfaces of the reinforcing boards.
- a multicomponent adhesive the components of which are applied to the surface of the motherboard and the at least one reinforcing board or the surfaces of the reinforcing boards.
- Surface coating can be applied to form a or as a connecting layer.
- the surface coating is preferably applied to the at least one before the warm or hot forming process
- the surface coating melts during the forming and a connection between the Main board and the at least one reinforcement board forms.
- Coating, in particular, the reinforcement board (s) enables an optimal and uniform connection with the base board up to the edge of the reinforcement board and, if necessary, from individual reinforcement boards to one another. In this way, a full-surface connection of the boards up to the edge region of the reinforcing board (s) can be achieved even with very complex shapes.
- An additional application of a bead of sealant in the edge region of the at least one reinforcing board is therefore no longer necessary, but can, however, be provided if this is desired.
- the connecting layer in the form of a surface coating of the at least one reinforcing board can also prove to be advantageous as a surface coating which is applied to the isolated shaped boards after the warm or hot forming.
- any adhesive and / or sealant for example an adhesive such as a silicone, in particular epoxy resin adhesive, polyurethane adhesive, hot melt adhesive, PUR dispersion adhesive, etc., can be used as the coating material.
- the coating can be done, for example, by rolling up, dipping, printing, gumming, etc.
- connection layer can completely cover the surface of the reinforcement board (s). However, it can also be embodied as a pattern or mask on the surface of the at least one reinforcing board and / or the base board, in particular surrounding the edge region of the reinforcing board essentially without gaps. Sometimes it is not absolutely necessary to cover the entire surface of the To provide the reinforcement board (s) with the respective connection layer, since a connection of the shaped boards is already supported by their shape and sealing is only useful in the edge region of the reinforcement board (s) for corrosion protection. When selecting the pattern or mask, this is advantageously matched to the forces acting on the finished molded part during operation, so that unwanted detachment of the blanks from one another can be avoided.
- the connecting layer preferably consists of a glass material and / or adhesive applied as a coating on the base plate and / or the at least one reinforcement plate, which melts during the forming process and forms a firm connection between the base plate and the reinforcement plate (s) during cooling.
- the hot-working process melts the glass material, which is applied particularly thinly, and forms an adhesive coating on the reinforcing sheet (s). Similar to an enamel layer, a firm connection between the adjacent board surfaces can occur when cooling. Corrosion protection is made possible, as is a firm connection of the molded boards.
- connection layer In the case of advantageous provision of shark warming of a base plate provided with a connection layer and at least one reinforcement plate together, an adhesive in particular can be used as the connection layer. This can melt during the forming process, harden on cooling and form a firm connection between the base plate and the at least one reinforcement plate.
- connection layer is preferably provided between a shaped base plate and at least one reinforcement plate in the form of an adhesive and / or melted and solidified glass material, which connects the base plate and the at least one reinforcement plate and / or several reinforcement plates to one another.
- a reinforcement board is preferably arranged and fixed on the base board and / or aligned to it by suitable means, or a plurality of reinforcement boards are arranged next to and / or one above the other on the
- Main board arranged and fixed and / or aligned by suitable means to each other and / or to the main board.
- suitable means particularly preferably, if only one reinforcement board is provided, it is arranged and fixed on the base board and / or aligned to it by suitable means, or if a plurality of reinforcement boards are provided, these are overlapping and / or abutting and / or spaced from one another in a partial area on the
- Main board fixed and / or aligned with each other by suitable means.
- stresses within a shaped workpiece or sheet metal structural part can be avoided or at least reduced, and rigidity increases can be carried out in a targeted manner, in particular if different material thicknesses are provided for the base plate and reinforcement plate (s).
- additional material reinforcements and thus very different stiffnesses can be achieved across the surface of the structural part. Differences in stiffness can also be generated by overlapping several reinforcement boards in their respective edge regions.
- only one reinforcement board can be provided in each case, which was possibly previously assembled from several parts, in particular of different material thickness.
- stud bolts or similar devices can be particularly preferably provided in the forming tool or the forming press.
- the reinforcing boards are preferably joined to one another in an abutting manner before the shaping process, in particular by providing a weld seam or other connecting seam.
- this butt seam can be leveled out during forming, so that no uneven transition points remain.
- the blanks are preferably fixed to one another by additional connections, in particular by welding, riveting or clinching, before the hot or hot forming and / or after the hot or hot forming or another connection method.
- additional connections in particular by welding, riveting or clinching, before the hot or hot forming and / or after the hot or hot forming or another connection method.
- the provision of an adhesive proves to be advantageous in that the heating temperature does not need to be kept in a range that is compatible with the solder, but rather in a range that is particularly suitable for semi-warm but also for hot forming Range can be set.
- the problem of flux corrosion, which is usually used for a soldering process is avoided.
- Figure 1 to 6 is a schematic view of the sequence of a hot forming process according to the invention by separating three reinforcing boards mounted on a base plate, and
- Figures 7 to 10 is a schematic view of the sequence of a second embodiment of an inventive Semi-hot forming process with the provision of a surface coating on reinforcement boards.
- FIG. 1 shows a first step of a hot forming process in which a flat, flat base plate 1 is first provided with three flat and flat reinforcement plates 2, 3, 4 of smaller dimensions than that of the base plate. This is also indicated by the arrows P.
- the reinforcement boards 2, 3, 4 are fixed on the surface 10 of the base board by a number of connection points, for example by six welding points 5, whereby a composite board 6 is formed. Alternatively, fixation can also be carried out using rivets, clinching or any other connection method. As a result, the blanks are secured against shifting during subsequent forming.
- the number of connection points depends on the sheet thickness of the blanks as well as the extent of the forming.
- the boards 1, 2, 3, 4 can only be aligned with one another without being fixed by welding points or the like.
- the reinforcement boards are arranged side by side and adjacent to each other on the motherboard. Their position and dimensions depend on the desired local rigidity. You can therefore also use reinforcement boards e.g. have different material thicknesses and / or different material thicknesses of the reinforcement boards, possibly also by joining several reinforcement boards together.
- the composite board is heated to a temperature suitable for hot forming, in particular to a temperature in the Range of 950 ° C.
- semi-hot forming can also be carried out, for example at temperatures in the range below 850 ° C., in particular 500 to 700 ° C., for example around 600 to 650 ° C.
- the heated composite blank is then passed on to a forming press 8, as outlined in FIG. 3.
- the warm or hot forming of the base plate and reinforcing plates fixed to one another takes place.
- the composite board is tempered by appropriate temperature control.
- the deformed composite plate in the form of a molded part which can be removed from the forming press 8 is shown in a perspective view in FIG.
- the three reinforcement blanks are fixed on the surface 10 of the base plate 1, which surface is now formed on the inside of the molded part. Their position relative to one another has not changed during the shaping process.
- the shaped reinforcement boards and the base board are separated again in the next processing step, which is outlined in FIG. The separation can take place after the warm or hot forming within the forming tool.
- the shaped blanks After the shaped blanks have been separated, they are provided on the surfaces facing one another with a connecting layer 11, for example with an adhesive layer and / or a sealant, which preferably also enables the surfaces to be joined or adhered to one another.
- the three reinforcement boards can either be applied on a common connection layer or on separate connection layers.
- the molded reinforcement boards 2, 3, 4 are placed back on the molded one Base board 1 added, an at least adhesive connection between the surfaces of the boards is now achieved by the connecting layer.
- the connecting layer preferably has a thickness such that the accuracy of fit of the jointly deformed boards is not jeopardized. In particular, it lies between the boards in such a way that an optimal, essentially gap-free fit is ensured.
- the addition of the shaped reinforcement boards 2, 3, 4 is indicated in FIG. 6 by arrows 9.
- the reinforcement boards can already be connected to one another, in particular before forming, in order to enable simple separation and reassembly.
- connection points in the form of e.g. Spot welds, rivets, etc. are provided.
- this additional connection can in principle also be omitted.
- the shaped reinforcement boards serve e.g. as internal reinforcement, the shaped base plate as external reinforcement of a vehicle B-pillar.
- Figure 7 shows the first processing step of an alternative method for warm or hot forming of blanks.
- the reinforcement boards 2, 3, 4 are first provided with a surface coating 20, 30, 40.
- This surface coating consists of a material which melts under the influence of heat and, at the latest when the shaped boards are cooled, bonds with them in an adhesive or adhesive manner, in particular an adhesive.
- a glass material such as sintered glass, can advantageously be used.
- the surface 10 of the motherboard and / or both the surface of the motherboard and that of the reinforcement boards can also be provided with a surface coating which, when heated, also enables a connection to the reinforcement boards, for example in the manner of a multi-component adhesive.
- the reinforcement boards 2, 3, 4 are then attached to the base board 1 and, in the case shown in FIG. 7, fixed at various points, for example by welding spots 5.
- This unit of composite board 60 thus created is subsequently introduced into an oven 7, as can be seen in FIG.
- the composite blank is heated to a temperature suitable for semi-hot forming (or possibly hot forming) and passed on to the forming press 8 (FIG. 9). It is used for semi-hot forming or hot forming with appropriate temperatures.
- the surface coating of the blanks melts and connects to the respective adjacent blank surface.
- a connection layer 12 is therefore formed directly during the forming, which enables a sealed and at the same time firmly connected unit of the shaped blanks.
- the connecting layer 12 is cooled and hardens in the process. Any gaps that remain or arise during the shaping between the base board and the reinforcement boards are filled by the connecting layer, as a result of which a tight unit for protection against corrosion can be created.
- Welding points further or these can be provided again, if necessary, for the additional connection of the shaped boards to one another.
- the combination of the fixing connection points applied before the forming and the connection layer can ensure a sufficiently firm hold of the shaped blanks on one another.
- a finished molded part can be removed from the forming press 8, as is shown in FIG. 9, which can be used as a structural part in vehicle construction, etc., after cutting to size, which usually follows the forming.
- connection layer 20 surface coating
