Description

[0001] The invention relates to a method for producing a hybrid component according to the preamble of patent claim 1. Furthermore, the invention relates to a hybrid component according to the preamble of patent claim 5.

[0002] Hybrid components are widely used in a wide range of applications, for example, in series production of passenger cars. Such hybrid components are used in a variety of structural components such as door supports, front-end supports, or bent cross members for bumpers. The key advantage of such hybrid components is that they are relatively lightweight and can be manufactured extremely precisely to meet specific needs. In particular, the inserts or metal components and / or fiber composite components ensure sufficient stability of the hybrid components.The plastic, which is usually injection-molded onto the metal components and / or fiber composite components, provides, on the one hand, appropriate stiffening, for example through ribs or the like, and, on the other hand, appropriate functional integration, so that the plastic can, for example, also have appropriate receptacles, contact surfaces, or the like for fixing and holding on or of connecting components.

[0003] A hybrid component of the type mentioned above is known from document DE 10 2009 014 244 A1.

[0004] Furthermore, it is known from the prior art to fasten such metal components to one another using a variety of possible connections. An example of such a connection is known from DE 101 51 659 B4. In this case, one of the metal components is perforated accordingly. The unperforated component is plastically deformed with the aid of a pressurized fluid through the corresponding hole in the perforated component into a cavity of the forming tool. In a further joining step, the plastically deformed area of ​​the component is reshaped by a punch, which counteracts the pressure of the pressurized fluid, so that an undercut is formed between the metal components.

[0005] Furthermore, a method, a device and an auxiliary joining part for mechanical joining are known from the document DE 199 27 103 A1.

[0006] The document DE 10 2005 037 914 B3 describes a method for setting punch rivets.

[0007] Furthermore, different welded rivet connections are known from the document DE 10 2008 031 121 A1.

[0008] The document DE 32 45 055 A1 concerns a blind rivet.

[0009] Furthermore, a profile composite component and a method for its production are known from document DE 100 22 360 A1.

[0010] Another punch rivet connection is described in DE 199 40 803 A1.

[0011] Furthermore, the document DE 10 2009 020 602 A1 describes a method for connecting a hollow profile to another component, whereby rivets in particular can be used for the connection.

[0012] Furthermore, the document DE 100 43 325 A1 deals with a door frame module for a vehicle door.

[0013] DE 10 2008 053 ​​102 A1 discloses a fastening arrangement of a body component to a body element of a motor vehicle, wherein the body element is formed from at least two components and wherein the body component and the body element are connected to one another via at least one punch rivet connection, in particular a hollow punch rivet connection, wherein the body component is directly connected to the facing one of the at least two components of the body element by means of the punch rivet connection and a free space for the punch rivet connection is provided in the region of the facing away one of the at least two components of the body element.

[0014] DE 10 2008 004 299 A1 discloses a punch rivet with a rivet head and an at least partially hollow cylindrical rivet shank, which forms a rivet foot which is annular in cross section and which runs into a rivet foot end face by the formation of a rivet foot inner chamfer and in which the transition from the rivet shank to the rivet head is formed by a lower head radius and a lower head chamfer, wherein the rivet foot wall thickness is at least 40% and preferably between 40% and 50% of the rivet foot outer radius and the width of the rivet foot end face is a maximum of 10% and preferably between 8% and 9% of the rivet foot wall thickness.

[0015] DE 20 2008 017 562 U1 discloses a rivet part with a slotted shaft.

[0016] DE 690 08 769 T2 shows a device for mounting fastening elements.

[0017] DE 10 2007 017 420 A1 discloses a method for producing a hollow profile to be provided with an opening in its circumference, which consists of a tubular support body and an injection-molded element. The support body is formed into its final shape from a blank using fluid internal high pressure, whereby the support body is overmolded with injection-molding material and then perforated to form the opening. To enable process-reliable production of the hollow profile formed as a composite component, it is proposed that the leakage fluid escaping from the internal high-pressure forming tool be removed by suction.

[0018] US patent application US 2008 / 0038576 A1 discloses a structural element for motor vehicles and a method for producing such an element. A structural element for a motor vehicle forming a front end, comprising: - an elongated, hollow metal cross member with a closed cross-section; - two plastic uprights, each upright being integrally molded onto the metal cross member and each upright being located entirely outside the contour of the metal cross member in each cross-section of the metal cross member, characterized in that each upright comprises at least two rings surrounding the metal cross member, the rings of each upright being spaced apart in the longitudinal direction, and the ratio of the axial length of each ring of a upright to the longitudinal spacing between the rings of that upright is less than 1.

[0019] DE 10 2007 060 628 A1 discloses a method for producing composite components from a profile and an injection-molded element. The injection-molded element is molded onto the profile so that the profile is gripped captively in the circumferential direction, and at least one form-locking element is formed on the profile, which is also gripped during injection-molded injection. To provide the injection-molded element of the produced composite component with a permanent hold on the profile, it is proposed that the form-locking element located between the ends of the profile be molded or formed to a limited extent in the circumferential direction and longitudinal extent.

[0020] The object of the present invention is to provide a method and a hybrid component of the type mentioned at the outset, in which the respective components, in particular metal components and / or fiber composite components, are connected to one another in a mechanically highly resilient manner and in which a particularly rapid and simple production of the hybrid component can be realized.

[0021] This object is achieved by a method and a hybrid component having the features of patent claims 1 and 5, respectively. Advantageous embodiments with expedient and non-trivial further developments of the invention are specified in the remaining patent claims.

[0022] In order to create a method of the type mentioned above, by means of which the components, in particular metal components and / or fiber composite components, of the hybrid component can be joined in a manner capable of withstanding high mechanical loads and which further ensures that the hybrid component can be manufactured extremely quickly and easily, the invention provides that the at least two components are joined to one another via at least one hollow punch rivet connection before they are provided with plastic to form the final hybrid component. Such a hollow punch rivet connection has the particular advantage that the metal components or similar components to be joined can be joined to one another in an extremely stable and rigid manner. This can be achieved, in particular, without the addition of heat by setting the corresponding hollow punch rivet.In particular, when the hollow rivet is set, the rivet shank expands and forms a closing head in the corresponding metal component. Hydraulic hollow punch rivets are manufactured, for example, by cold extrusion, tensioning, or impact. This type of joining method is particularly advantageous when a closed hollow profile part is to be joined to an open profile part, such as a sheet metal part. This type of configuration is frequently encountered in structural components of passenger car bodies, such as door supports, front-end supports, or bent cross members for bumpers.

[0023] The described method is particularly suitable when relatively little space is available for feeding the hollow punch rivets, for example because corresponding plastic ribs or similar plastic elements are provided in the area of ​​the respective hollow punch rivet connection.

[0024] In a further embodiment of the invention, it has proven advantageous if the hybrid component is manufactured using a combined forming and plastic injection molding process, in particular a combined hydroforming and plastic injection molding process. This process allows the hybrid component to be manufactured particularly quickly and cost-effectively, while also being particularly suitable for the load.

[0025] A further advantageous embodiment provides for at least one hollow punch rivet to be pre-fixed to one of the metal components outside of a tool that creates the hollow punch rivet connection. This type of pre-fixation is particularly suitable when there is insufficient space available for feeding the hollow punch rivet.

[0026] In a further embodiment of the invention, it has proven particularly advantageous if, before the respective hollow self-piercing rivet is pre-fixed, a receiving opening is made in the corresponding component, in particular a metal component and / or fiber composite component. In other words, the respective component is first pre-drilled or pre-punched and then the hollow self-piercing rivet is pre-fixed in the corresponding hole. For this purpose, an expanding mandrel can be used if necessary, with which the hollow self-piercing rivet is slightly expanded and thus particularly securely fixed to the corresponding metal component and / or fiber composite component. Alternatively, it is also conceivable for the corresponding metal component and / or fiber composite component to which the hollow self-piercing rivet is to be pre-fixed not to be pre-drilled or pre-punched.In this case, the rivet is pressed into the corresponding metal component and / or fiber composite component, only to the extent that it is flush with the corresponding later exit side.

[0027] According to the invention, it is further provided that at least one hollow punch rivet is fed via a gripper device to a tool that creates the hollow punch rivet connection. Such a gripper device is particularly suitable for appropriately positioning a plurality of hollow punch rivets with the tool open, so that they can then be pressed in and formed with the tool closed in the combined internal high-pressure forming and plastic injection molding process such that the individual hollow punch rivet connections are created between the corresponding metal components.

[0028] Furthermore, the invention provides that at least one hollow punch rivet is used, the rivet shank of which is slotted for improved gripping of the shank end of the rivet shank.

[0029] Alternatively, a further embodiment of the invention provides for at least one hollow punch rivet to be fed to a tool that creates the hollow punch rivet joint via a rivet feed device. Such a method is particularly suitable if sufficient space can be provided within the tool for the feed.

[0030] In a further embodiment of the invention, at least one hollow self-piercing rivet is used, the head of which, after the hollow self-piercing rivet connection has been established, is flush with a component surface of the corresponding component. Thus, a flat or smooth functional surface can be provided following the production of the hollow self-piercing rivet connection.

[0031] Alternatively, a hollow self-piercing rivet can be used, with its head protruding from the surface of the corresponding component after the hollow self-piercing rivet connection has been made. In this case, the head can be used for magazine feeding. This is possible because the head can be used as a guide surface in the tool.

[0032] The advantages described above in connection with the method according to the invention apply equally to the hybrid component according to claim 8.

[0033] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings, which show: Fig. 1 a perspective view of a door carrier designed as a hybrid component for a body for a passenger car, in which a plurality of metal components and / or fiber composite components are connected to one another and at least partially provided with plastic, wherein respective metal components and / or fiber composite components of the hybrid component are connected to one another via a plurality of hollow punch rivet connections and subsequently provided with plastic in a combined internal high-pressure forming and injection molding process; Fig. 2a and Fig. 2b a partial perspective view and a partial sectional view along the line IIb-IIb in Fig. 2a by one of the metal components and / or fiber composite components to which a plurality of hollow punch rivets have been pre-fixed outside a tool producing the hollow punch rivet connections; Fig. 3a and Fig. 3b respective sectional views through a hollow punch rivet pre-fixed to the corresponding metal component and / or fiber composite component, wherein according to Fig. 3a, a receiving opening has been made in the corresponding metal component and / or fiber composite component in front of the pre-fixed hollow punch rivet, and wherein according to Fig. 3b the hollow punch rivet has been pre-fixed to the metal component and / or fibre composite component without prior provision of a receiving opening; Fig. 4 show respective sectional views of hollow punch rivets according to two embodiments, which have been introduced into a corresponding metal component and / or fiber composite component, wherein the head of the left hollow punch rivet is flush with a component surface of the corresponding metal component and / or fiber composite component after the hollow punch rivet connection has been established, and wherein the head of the hollow punch rivet shown on the right protrudes in a raised manner from the component surface of the corresponding metal component and / or fiber composite component after the hollow punch rivet connection has been established; Fig. 5 a sectional view and a bottom view of an embodiment of the hollow punch rivet according to the invention, which in the present case is designed as a semi-hollow punch rivet with a slotted rivet shank; Fig. 6 a front view of a metal component in the form of an open profile or sheet metal part, which is fastened to the other metal component and / or fiber composite component in the form of a closed hollow profile part by means of a plurality of hollow punch rivet connections, wherein the two metal components and / or fiber composite components have been additionally provided with plastic; Fig. 7 a perspective view of a tool for producing a door support according to Fig. 1, wherein a gripper device according to the invention can also be seen, via which a plurality of hollow punch rivets can be fed to the tool producing the hollow punch rivet connections; Fig. 8a and Fig. 8b respective schematic sectional views of the tool according to Fig. 7 with respective punches for producing the corresponding hollow punch rivet connections, wherein the hollow punch rivets are accommodated within respective corresponding receptacles; Fig. 9 a perspective view of a punching head of a rivet feeding device via which the respective hollow punch rivets can be brought into the opened tool; and in the Fig. 10a and Fig. 10b each shows a partial and schematic sectional view through the tool with the rivet feeding device and the punching head, by means of which the hollow punch rivet connections can be produced.

[0034] In Fig. Figure 1 shows a perspective view of a hybrid component 10 for a body of a passenger car. More specifically, the hybrid component 10 is a door carrier on a side of the vehicle, which is equipped with, among other things, exterior paneling and interior trim.

[0035] The hybrid component 10 comprises a substantially U-shaped metal component 12, which in this case is designed as a closed hollow profile part—for example, from an extruded profile that has been subsequently formed. A plurality of further metal components 14, 16, 18 in the form of corresponding support elements are connected to this metal component 12 in a manner described in more detail below. These metal components 14, 16, 18 are designed as open profile parts or correspondingly formed profile surfaces.

[0036] The hybrid component 10 or the metal components 12, 14, 16, 18 are at least partially provided with a plastic 20, through which, for example, ribs 22 or functional areas or functional elements such as screw receptacles, brackets, bearing points, or the like can be formed. In the present embodiment, a preferably fiber-reinforced polyamide material can be provided as the plastic 20.

[0037] Alternatively, the hollow profile part can also be made of a fiber-reinforced plastic (FRP) material, in particular at least partially of unidirectional long carbon fibers. The hollow profile can be a textile in the form of a woven or knitted fabric. The matrix can be thermoset or thermoplastic.

[0038] Based on the Fig. 2a and Fig. 2b, the concrete fixing of the metal component 14 to the metal component 12 will now be explained by way of example: Fig. 2a in a partial and enlarged perspective view the metal component 14 in its fastening area with the metal component 12. Fig. Figure 2b shows a sectional view along the line IIb-IIb in Fig. 2a.

[0039] Out of Fig. 2a, it is particularly evident that the metal component 14 is attached to the metal component 12 via several hollow punch rivets 24. As can be seen from Fig. 2a, but the representations show the Fig. 2a and Fig. 2b shows the respective hollow punch rivets 24 in a pre-fixed position. This means that the hollow punch rivets 24 are already pre-fixed to the corresponding metal component 14 outside of a tool that creates the hollow punch rivet connections. More precisely, in the present case, the respective hollow punch rivets 24, which are designed as semi-hollow punch rivets, are pre-fixed in the metal component 14 or metal sheet on the punch side.

[0040] In the Fig. 3a and Fig. 3b shows possible variants of the pre-fixation of the respective hollow punch rivet 24 in a respective schematic sectional view. The hollow punch rivets are fed to the corresponding joining points with the sheet metal or metal component 14 in a punching tool (progressive tool) via punching heads and conventional feeding technology.

[0041] As now Fig. 3a, a fastening variant is shown in the present case in which the sheet metal or the metal component 14 is first pre-drilled or pre-punched and then, in a subsequent station, the hollow punch rivet 24 is introduced or fixed into a correspondingly pre-drilled or pre-punched receiving opening 26 via a punching head and a corresponding part preparation. This fixing process can be supported by an expanding mandrel 28, indicated by dashed lines, which expands a rivet shank 30 of the hollow punch rivet 24 accordingly and thus ensures secure pre-fixing to the metal component 14. The hollow punch rivet 24 is inserted into the receiving opening 26 at most until it is flush with a broad side 32 facing the die side of the sheet metal or metal component 14. In other words, the hollow punch rivet 24 is intended toMetal component 14 does not penetrate in such a way that its rivet shank 30 protrudes beyond the corresponding broad side 32.

[0042] In the variant according to Fig. 3b, the hollow punch rivet 24 has been pre-fixed without pre-punching, and again only to the extent that it does not protrude beyond the broad side 32 on the die side of the sheet metal or metal component 14. A punch slug 34 resulting from the punching of the hollow punch rivet 24 is, for example, received in the cavity of the hollow punch rivet 24.

[0043] In Fig. 4 shows two possible positions of the respective hollow punch rivet 24 after the hollow punch rivet connection has been made. In the left illustration of Fig. 4 shows a hollow punch rivet 24, the head 36 of which, after the hollow punch rivet connection has been made, is flush with a component surface 38 of the corresponding metal component 14. In this case, a flat functional surface is created. Fig. In the case shown on the right in Figure 4, a hollow punch rivet is used, the head 36 of which protrudes from the component surface 38 of the corresponding metal component 14 after the hollow punch rivet connection has been established. In this case, the head 36 can be used for a magazine-style rivet feed. This is possible because the head 36 can be used as a guide surface in the tool.

[0044] The Fig. Figure 5 shows a sectional view and a bottom view of corresponding embodiments of the hollow punch rivet 24. The hollow punch rivet 24 can have a special rivet geometry with a very small ratio between the length and its diameter. Furthermore, the rivet shank 30 can optionally - as in Fig. 5 is shown on the right - can be designed with a slot, which ensures that the shaft end of the rivet shaft 30 connects positively to the respective component - for example, the metal component 12 - or claws into it in an improved manner. The claw connection or consolidation can be particularly advantageous in fiber composite semi-finished products and those semi-finished products reinforced with steel strands and / or steel fibers.

[0045] In Fig. 6 is a partial front view of the arrangement of the metal component 14 on the metal component 12 according to Fig. 1 or the Fig. 2a and Fig. 2b, after the hollow punch rivets 24, designed as hydro-semi-hollow punch rivets, have each been deformed accordingly and thus connected to the metal component 12, and after the hollow punch rivet connections have been produced, the metal components 12, 14 have been provided with the plastic 20. The actual joining process was carried out in a manner described in more detail below in an internal high-pressure forming injection mold. It can be seen that ribs 22 of the plastic 20 run directly next to the hollow punch rivets 24, thus leaving little space for the hollow punch rivets 24 to be fed in.

[0046] In Fig. Figure 7 shows a perspective view of an open internal high-pressure forming injection molding tool 40. Additionally, a possible concept for rivet provision using a gripper device 42 is shown, in which the hydraulic semi-tubular self-piercing rivets 24 are first positioned in a gripper via mandrels. Using this gripper, all semi-tubular self-piercing rivets 24 are then brought into the open tool 40 at the corresponding joining points. This process can be performed for both halves of the tool 40.

[0047] The hollow punch rivets 24 are held in the tool 40 by means of respective Fig. 8a and Fig. 8b, which are arranged within the corresponding tool half 48 of the tool 40. In the Fig. 8a and Fig. In Figure 8b, these rivet receptacles 46 are visible as well as the metal components 12, 14 to be joined.

[0048] Each rivet receptacle 46 is assigned a corresponding punch 50, by means of which the respective hollow punch rivet 24 is driven into the respective corresponding wall of the metal components 12 or 14. The present embodiment differs from that according to the Fig. 2a and Fig. 2b and 3a and 3b, in particular, in that the hollow punch rivets 24 are not pre-fixed to the metal component 14. Rather, the positioning is achieved by the precise arrangement within the corresponding rivet receptacle 46.

[0049] In Fig. 8b shows possible devices within the rivet holder 46 by means of which the corresponding hollow punch rivets 24 can be held in place. In the upper illustration of Fig. 8b, a circumferential magnetic ring 56 is visible in the sectional view, by means of which the positioning of the hollow punch rivet 24 takes place. In the lower illustration of Fig. 8b shows, as an alternative to the magnetic ring 56, a spring arrangement with respective springs 58, by means of which the corresponding hollow punch rivet 24 is to be held in place.

[0050] The joining of the metal components 12, 14 takes place by appropriately moving the punches 50, with the die being formed by a pressurized fluid 60, with which the metal component 12, designed as a hollow profile, is subjected to internal high pressure. The hollow punch rivets 24, which are subjected to a pressing force via the punches 50, cut the punch-side metal component 14 in a first phase of the joining process, with the punch slug 34 in this case being received in the cavity of the hollow punch rivet 24. As the hollow punch rivet 24 penetrates further—particularly into the metal component 12, which is designed as a hollow profile and is pressurized with the pressurized fluid 60—the rivet shank 30 expands and forms a closing head in the internal high-pressure forming part, namely the metal component 12, whereby this metal component 12 is not completely intersected by the rivet base or rivet shank 30. This results in the two metal components 12, 14 being secured to one another.In conjunction with this, the internal high-pressure forming of the metal components, in particular the metal component 12, can be carried out by applying pressure with the pressurized fluid 60. The internal high-pressure forming of the metal components 12, 14, 16, 18 can take place before, during, or after the insertion of the hollow punch rivet 24.

[0051] Following the internal high pressure forming and the joining of the metal components 12, 14, 16, 18, the Fig. 7, an injection molding process is carried out, in which the metal components 12, 14, 16, 18 are at least partially provided with the plastic 20 in order to achieve sufficient stiffening or the formation of individual functional components such as receptacles, consoles or the like.

[0052] Overall, it can thus be seen that in the present case the rivets 24 are pressed in via deformable punches 50, wherein the pressure fluid 60, which can be a gas or water emulsion, for example, is used to hold them within the closed profile of the metal component 12.

[0053] In Fig. 9 shows a perspective view of a punching head 62, via which the rivets 24 can be brought into the opened internal high-pressure forming injection molding tool by means of feed rails or feed hoses, which can be connected, for example, to the receptacle 64 of the punching head 62.

[0054] In the Fig. 10a and Fig.10b shows a schematic sectional view of the tool 40 with a corresponding rivet feed device 66. In particular, in addition to the rivet feed device 66, respective punches 68 are visible, by means of which the corresponding metal component 12 can be closed for pressurization with the pressurized fluid 60. The hollow punch rivets 24 are brought into the corresponding rivet receptacles 46 via the rivet feed device 66, so that they can be introduced into the respective walls 52 or 54 of the corresponding metal components 12 or 14 by means of the respective corresponding punch 50.

[0055] Overall, it can thus be seen that the present method solves the problem of feeding and pre-fixing rivets 24 suitable for internal high-pressure forming and setting or pressing the rivets 24 into the metal components 12 to 18 to be joined. The entire process takes place in an internal high-pressure forming injection molding tool, whereby the corresponding metal components 12 are first joined to one another using hollow punch rivet connections and the corresponding plastic 20 is then introduced by injection molding. The closed and open profiles are connected via the rivets 24 - by means of the pressurized fluid 60 - using the pressure generated in the internal high-pressure forming process, via movable punches 50 and pressure. After the connection, the respective metal components 12 to 18 are overmolded with plastic at a plurality of joining points of the structural assembly.This results in a reduction in the cost and weight of the corresponding hybrid component 10 and a reduction in operating costs. This ensures process-reliable and stable pre-fixing of the metal components 12 to 18 and a process-reliable feeding of the rivets 24. The component geometry enables flexible rivet fixation as a modular system. This results in an increase in the number of joints that can be realized in the series tool for complex assemblies such as door carriers, bending beams of bumpers, or front-end beams. This also enables cost-effective realization of crash-resistant and highly stressed structural and semi-structures with high rigidity and reliability.
