The invention describes a composite component, in particular for forming a motor vehicle body part, which has at least one casting (1) made of a light metal and/or a light metal alloy, in which the casting (1) is at least Parts (3, 5) are connected to at least one other component (2, 4) consisting of substantially thin-walled plate-like material. As a result, a load- and weight-adapted structure can be produced in an optimal way from light metal composite components. Take the tailgate of a motor vehicle as an example.
Description
特别在车身的生产中，允许在一个构件中的多种材料特性能够根据运转工况和安装条件精确协调一致的材料和材料组合应用得越来越多。到目前为止，由金属薄板或薄壁剖面件制成的构件被应用在这方面，例如，用这些构件主要通过热接合方法从大量单件中制造出车身。Particularly in the production of car bodies, materials and material combinations are increasingly being used which allow the properties of various materials in one component to be precisely matched to the operating and installation conditions. Up to now, components made of sheet metal or thin-walled sections have been used in this context, for example, to manufacture car bodies from a large number of individual parts, mainly by means of thermal joining methods.
在车辆构造中，越来越多地利用由轻金属材料或轻金属合金组成的材料，用这些材料生产机动车辆的车身外皮或其它承载构件，直到生产完全由轻金属构成的车身。这些轻金属主要是铝，现在越来越多地也用镁，二者在其加工技术角度的实用性和特有的材料价值方面都特别受欢迎。In vehicle construction, materials consisting of light metal materials or light metal alloys are increasingly being used for the production of body skins or other load-carrying components of motor vehicles up to car bodies consisting entirely of light metal. These light metals are mainly aluminum and increasingly also magnesium, both of which are particularly popular for their practicality from a processing technology point of view and their specific material value.
如果这些轻金属材料被用在车辆构造中，特别成问题的是，轻金属板的强度特性对某些车辆部件所承受的载荷来说是不够的。比较成问题的、并且已经尝试过的是使用轻金属板代替车身大面积钢件--例如外皮--用铝件代替，因为它们通常不承受特别高的载荷。然而，特别是在构件承受高机械载荷的情况下，会出现单个载荷和载荷群，使得不能够用相宜形状的轻金属板来生产这些功能件。或者构件由于过高的单个载荷而过早地损坏，或者出现永久失效都远远早于钢件由于疲劳断裂的情况。It is particularly problematic if these light metal materials are used in vehicle construction that the strength properties of the light metal sheets are not sufficient for the loads to which certain vehicle components are subjected. More problematic, and one that has already been tried, is the use of light metal sheets to replace large areas of steel in the car body - such as the outer skin - with aluminum parts, since they are generally not subject to particularly high loads. However, especially in the case of components subjected to high mechanical loads, individual loads and load groups can occur, making it impossible to produce these functional parts from suitably shaped light metal sheets. Either the component fails prematurely due to too high a single load, or permanent failure occurs much earlier than the steel part fails due to fatigue.
提高轻金属构件强度的一个可能性是，对于轻金属构件的生产，不是使用较薄的轻金属板，而是使用轻金属或轻金属合金制成的铸件，根据铸造技术的可能性，这些铸件可在较高载荷区提供更多的材料，从而可以一种更合适的方式为特定载荷来进行设计。然而，根据铸造所要求这种铸造轻金属件的最小壁厚，这些件在不承受如此高载荷区也比只用薄轻金属板生产的轻金属件重得多，结果是使用轻金属材料所带来的重量减少大部分又失去了。One possibility to increase the strength of light metal components is to use, for the production of light metal components, not thinner light metal sheets but castings made of light metal or light metal alloys, which, according to the possibilities of casting technology, can be used at higher loads Zones provide more material that can be designed in a more appropriate way for a specific load. However, according to the minimum wall thickness of such cast light metal parts required by casting, these parts are also much heavier than light metal parts produced only with thin light metal plates in areas that are not subjected to such high loads. The result is that the weight brought by the use of light metal materials Most of the reduction is lost again.
因此，本发明的目的在于，使轻金属构件可以设计得更加适于特定载荷，可以充分利用轻金属结构的优点。Therefore, the object of the present invention is to make light metal components more suitable for specific loads and to make full use of the advantages of light metal structures.
实现该目的的方案如权利要求1的特征所述。从属权利要求描述了优选改进方案。The solution to this object is described by the features of claim 1 . The dependent claims describe preferred developments.
本发明描述了一种复合构件，其至少有一个用轻金属和/或轻金属合金制成的铸件。根据本发明，该铸件至少在某些部分与至少一个另外的由基本薄壁板状材料组成的构件相连接。通过这样形成一种复合物，就可以生产为特定载荷适当设计的构件，其中，无论是例如要承受较高载荷处或是一些其他要求材料积聚的地方，铸件所提供的材料积聚布置从模铸角度讲很简单，因而也很便宜。在不承受高载荷区，相应由薄壁板状材料制成的构件可以安装并连接到铸件上。这种板状材料可以低费预加工好，放在仓库里。这特别克服了这样一个问题，即这些区域的复合构件不能用铸造方法生产，使其壁厚达要求的薄度，因此，如果与铸件一起制造，将不合理地增加复合构件的重量。The invention describes a composite component comprising at least one cast part made of a light metal and/or a light metal alloy. According to the invention, the cast part is connected, at least in sections, to at least one further component consisting of a substantially thin-walled sheet-like material. By forming a composite in this way, it is possible to produce components that are properly designed for specific loads, where, whether for example where higher loads are to be borne or some other place where material accumulation is required, the material accumulation arrangement provided by the casting is changed from die casting to It's simple in terms of perspective, and therefore cheap. In areas not subject to high loads, corresponding components made of thin-walled sheet-like material can be installed and connected to the casting. This plate-shaped material can be pre-processed at low cost and placed in the warehouse. This overcomes in particular the problem that the composite member in these areas cannot be produced by casting to the required thinness of the wall and, therefore, would unreasonably increase the weight of the composite member if manufactured with the casting.
特别有利的是，板状材料包括一种轻金属和/或一种轻金属合金，特别是可以用铝和/或镁和/或它们各自的合金来生产板状材料。这些材料把低单位材料重量与有利的强度特性结合起来；这样，它们的使用使复合构件比钢构件重量明显降低。It is particularly advantageous if the sheet-like material comprises a light metal and/or a light metal alloy, in particular the sheet-like material can be produced from aluminum and/or magnesium and/or their respective alloys. These materials combine low unit material weight with favorable strength properties; thus, their use enables composite members to have significantly lower weight than steel members.
如果板状材料用滚轧生产，则其预加工费用特别有利，因为，作为其结果，连续处理工序可与被滚轧材料的特别有利的材料特性结合起来。If the plate-shaped material is produced by rolling, its preprocessing costs are particularly favorable, since, as a result, continuous processing steps can be combined with particularly advantageous material properties of the rolled material.
板状材料还可包括塑料，塑料把适合于特定载荷的特性与低预加工成本结合起来。例如，还可使用复合塑料材料。The sheet-like material may also comprise plastics, which combine properties suitable for specific loads with low pre-processing costs. For example, composite plastic materials may also be used.
一种改进方案是，在复合件中铸件具有一个基本上加强的和/或承载的功能。其结果是，可特别有利地利用铸造技术的优点和其适合于特定载荷的设计，这样生产成本保持较低。In one refinement, the cast part has an essentially reinforcing and/or load-bearing function in the composite part. As a result, the advantages of casting technology and its adaptation to specific loads can be used particularly advantageously, so that the production costs are kept low.
特别有利的是，铸件包括一个轻金属压力模铸。模铸技术使得尺寸非常精确从而可进行优质铸造，这样用这种方法生产的构件具有非常好的特性。It is particularly advantageous if the casting comprises a light metal pressure die casting. Die-casting technology allows very precise dimensions for high-quality casting, so that the components produced by this method have very good properties.
强度特性的进一步改进是通过使铸件具有室状区域以增强和/或加强来获得的。其结果是，可在铸件中引入从铸造角度讲便于制造的选择增强。Further improvements in strength properties are obtained by having the castings have chambered regions for reinforcement and/or reinforcement. As a result, selective enhancements that facilitate fabrication from a casting point of view can be introduced into the casting.
在另一种改进方案中，包括板状材料的构件布置在基本上低载荷区域的复合构件上。其结果是，重量减少的优点可被特别广泛地应用，因为如果载荷低，这个构件还可只用非常薄的壁制造。其结果是，与通过铸造技术制造的较厚壁的构件相比，重量减少非常明显。In another refinement, the component comprising sheet-like material is arranged on the composite component in the substantially low-load region. As a result, the advantage of the weight reduction can be exploited particularly broadly, since this component can also be produced with only very thin walls if the loads are low. The result is a significant weight reduction compared to thicker-walled components produced by casting techniques.
关于铸件和由薄板状材料组成的构件间的连接，很有利的是，铸件至少在某些部分与由薄板状材料组成的构件通过热接合方法连接。其结果是，可建立牢固的和均匀的连接，可靠地保证机械载荷在铸件和由薄板状材料组成的构件间传递。特别有利地可使用激光焊接和/或压薄滚焊方法。With regard to the connection between the casting and the component consisting of sheet-like material, it is advantageous if the casting is connected, at least in sections, to the component consisting of sheet-like material by means of thermal bonding. As a result, a firm and uniform connection can be produced, which reliably ensures the transmission of mechanical loads between the cast part and the component consisting of sheet-like material. Laser welding and/or mash seam methods can be used particularly advantageously.
在另一种改进方案中，铸件至少在某些部分与由薄板状材料组成的构件通过卷边方法连接。这种连接技术特别适用于因材料组合不能使用热接合方法的情况下。In another refinement, the cast part is connected at least in sections to the component made of sheet-like material by means of a crimping method. This joining technique is particularly suitable when thermal joining methods cannot be used due to material combinations.
另一种改进方案是，铸件至少在某些部分与由薄板状材料组成的构件通过粘接方法连接。这种连接可特别应用于铸件和不承受高载荷的由薄板状材料组成的构件间的连接情况。Another refinement consists in that the cast part is joined at least in sections to the component made of sheet-like material by means of adhesives. This type of connection can be used in particular in the case of connections between castings and components made of sheet-like material that are not subjected to high loads.
同样，铸件和由薄板状材料组成的构件至少在某些部分可通过冲压铆接或压力接合来连接，这样使得无需对要在连接区域连接的两个件进行复杂的预加工。Likewise, castings and components made of sheet-like material can be joined at least in parts by punch riveting or press joining, which eliminates the need for complex prefabrication of the two parts to be joined in the joining area.
对于本领域普通的技术人员来说很显然，在铸件和由薄板状材料组成的构件间的前述连接以及其它其所熟悉的连接也包括在本发明范围之内。特别是，结合的粘接/冲压铆接，粘接/点焊和粘接/压力接合连接在试验中被证明是有利的，因为考虑到接触腐蚀，用于一个表面区域的粘接剂或胶带或者胶条形式的粘接方法可同时起到连接密封化合物和绝缘层的作用。It will be obvious to a person skilled in the art that the aforementioned connections between castings and components made of sheet-like material, as well as other connections familiar to him, are also included within the scope of the present invention. In particular, combined bonded/punched riveting, bonded/spot welded and bonded/pressure joint connections have proven to be advantageous in tests, since adhesives or tapes for one surface area or The bonding method in the form of an adhesive strip acts as a joint between the sealing compound and the insulating layer at the same time.
一个特别有利的精制复合构件是，复合构件是一个车身件，最好是机动车辆车身外皮的一部分。特别是在汽车工程中，更能显示出根据本发明的复合构件的优点，因为复合结构适合于大量生产，同时伴随明显的重量减少。A particularly advantageous finished composite component is that the composite component is a body part, preferably part of a motor vehicle body skin. Especially in automotive engineering, the advantages of the composite component according to the invention can be seen even more, since the composite structure is suitable for mass production with a simultaneous significant weight reduction.
在一种改进方案中，由薄板状材料组成的构件可以是车身外皮的一部分并且至少部分地包过内铸件。其结果是，铸件至少基本上隐藏在机械车辆的外皮内，这特别有利于车身形状的整体美学效果。In a refinement, the component made of sheet-like material can be part of the outer skin of the vehicle body and at least partially surround the inner casting. As a result, the casting is at least substantially hidden within the outer skin of the mechanical vehicle, which is particularly beneficial to the overall aesthetic effect of the body shape.
在另一种改进方案中，铸件可以至少在某些部分是车身外皮的一部分并且至少部分地围绕由薄板状材料组成的内部构件。其结果是，例如，铸件中为结构或功能原因，如窗户或类似结构，所要求的车身上的开口可被板状材料封闭。In a further refinement, the cast part can be part of the outer skin of the vehicle body at least in sections and at least partially surround the inner component composed of sheet-like material. As a result, for example, openings in the body of the casting that are required for structural or functional reasons, such as windows or the like, can be closed by the sheet-like material.
特别有利的是，复合构件是机械车辆的后背箱盖。It is particularly advantageous if the composite component is a boot lid of a mechanical vehicle.
根据本发明的一个特别有利的构件设计特别应用在机械车辆车身件上，如附图所示，其中：A particularly advantageous component design according to the invention is used in particular on mechanical vehicle body parts, as shown in the accompanying drawings, in which:
图1为根据本发明的复合构件用作机动车辆后背箱盖形式的平面图。FIG. 1 is a plan view of a composite component according to the invention in the form of a tailgate for a motor vehicle.
图2是该复合构件沿图1中B-B线以折边缝为例的剖面图。Fig. 2 is a sectional view of the composite member along line B-B in Fig. 1, taking hem seam as an example.
图3是该复合构件沿图1中A-A线以激光焊接缝为例的剖面图。Fig. 3 is a cross-sectional view of the composite member along line A-A in Fig. 1, taking a laser welded seam as an example.

图1至图4就原理而论借助机动车辆后背箱盖实施例展示了如何设计和使用根据本发明的复合构件。复合构件的结构只是一般性展示，其可转换成大量应用和变型。1 to 4 show in principle how the composite component according to the invention can be designed and used with the aid of a motor vehicle tailgate embodiment. The structure of the composite member is only a general presentation, which can be translated into a large number of applications and variations.
图1所示为如广泛应用在后背仓门式小型车辆的机动车辆后背箱盖的平面图。FIG. 1 is a plan view of a motor vehicle tailgate as widely used in hatchback small vehicles.
在传统板钢技术中，这种后背箱盖通常用一个内板钢件和一个外板钢件连接起来以帮助形成车身的外皮，还可以在内和/或外板钢件上安装附加的板钢增强或支撑。In traditional sheet steel technology, this tailgate is usually connected with an inner and an outer sheet steel to help form the outer skin of the body, and additional Plate steel reinforcement or support.
在根据本发明的后背箱盖形式的本复合构件实施例中，后背箱盖包括一个框架1，其加强了后背箱盖，是通过镁或铝压力模铸制造的一个铸件。框架1装在机动车车身的内侧，然后面向乘客舱。在所示后背箱盖承担增强功能的情况下，内框架1的尺寸基本上与车辆后开口(未示)的顶部相等，并围绕所述开口沿其外侧界限基本上形成一个矩形框架。在图2至图4中更详细展示的该内框架的横截面形成了一个圆周形槽状通道，其精确设计由与强度和铸造工艺相关的技术要求直接控制。在框架1的该槽状横截面中可同时布置内铸的增强模腔6，其可在例如承受特别高的机械载荷的区域对框架1产生附加的增强作用。框架1用于容纳一个后窗。In this embodiment of the composite component according to the invention in the form of a tailgate, the tailgate comprises a frame 1, which reinforces the tailgate, being a casting produced by magnesium or aluminum pressure die casting. The frame 1 is mounted on the inside of the vehicle body, then facing the passenger compartment. In the case where the tailgate is shown assuming the reinforcing function, the inner frame 1 is substantially equal in size to the top of the vehicle's rear opening (not shown) and forms a substantially rectangular frame around said opening along its outer limits. The cross-section of this inner frame shown in more detail in Figures 2 to 4 forms a circumferential channel, the precise design of which is directly governed by the specifications related to strength and casting process. In this channel-shaped cross-section of the frame 1 , an in-cast reinforcement cavity 6 can simultaneously be arranged, which can provide an additional reinforcement of the frame 1 , for example in regions subjected to particularly high mechanical loads. Frame 1 is used to accommodate a rear window.
内框架1通过由滚轧的镁或铝板形成的外薄板4包向车辆外表面。在该实施例中外薄板4被设计成后背箱盖整个外表面上的一个件。在后背箱盖的上部，外薄板4封闭了朝向外表面的内框架1并与所述框架一起形成了一个封闭的中空轮廓。因为由于外薄板4，图1平面图中内框架1的同时铸造的室状增强腔6事实上被挡住因而不再会被看到，所以它们在图1中仅用虚线表示出。The inner frame 1 is clad to the outer surface of the vehicle by an outer sheet 4 formed from rolled magnesium or aluminum sheet. In this exemplary embodiment, the outer sheet 4 is designed as one piece on the entire outer surface of the tailgate. In the upper part of the tailgate, the outer sheet 4 closes the inner frame 1 facing the outer surface and together with said frame forms a closed hollow contour. Since the simultaneously cast chamber-like reinforcing cavities 6 of the inner frame 1 in plan view of FIG. 1 are virtually blocked and thus no longer visible due to the outer sheet 4 , they are only indicated in FIG. 1 by dashed lines.
在图1中，在框架1的下面有一个内裙板2，其被装在以后是后背箱盖的车辆内侧面上并固定在框架1上。被安装好后，由薄壁滚轧镁板形成的内裙板2与外薄板4的底部一起封闭了车辆后开口的下部。由薄壁板状材料制造的裙状构件内裙板2的主要任务是封闭车辆的底部后开口，后背箱盖锁机构的锁盒10通常安装在内裙板2的下部边缘部分。然而，尾板2基本上具有镶板的功能，其精确的造型还可具有功能区，例如后背箱盖把手的安装空间。作用在内裙板2上的机械载荷比较低；因此，由于强度原因，对于该结构完全薄板金属设计足够了。内框架1延伸进该区域也被认为是不应该的，因为这将使得框架1变得沉重得多并且更加复杂不易生产。因此，内框架1被限制在仅处于后开口的上部，而在后开口的下部，大体上板状的内裙板2通过例如焊缝连接3附着在框架1上作为一个裙板。其结果是，做成一个稳定铸件的内框架1的强度优点可与后开口下部轻量内薄板金属覆盖裙板2的重量优点结合起来。In FIG. 1 , underneath the frame 1 there is an inner skirt 2 , which is mounted on the inside of the vehicle, which is then the tailgate, and fastened to the frame 1 . When installed, the inner skirt 2 formed of thin-walled rolled magnesium sheet together with the bottom of the outer sheet 4 closes the lower part of the rear opening of the vehicle. The main task of the inner skirt 2 made of thin-walled plate material is to close the bottom rear opening of the vehicle, and the lock box 10 of the tailgate lock mechanism is usually installed on the lower edge of the inner skirt 2 . However, the tailgate 2 basically has the function of a panel, and its precise shape can also provide functional areas, such as the mounting space for the tailgate handle. The mechanical loads acting on the inner skirt 2 are comparatively low; therefore, for reasons of strength, a completely sheet metal design is sufficient for the structure. It is also considered undesirable for the inner frame 1 to extend into this area, as this would make the frame 1 much heavier and more complicated to produce. Thus, the inner frame 1 is limited only in the upper part of the rear opening, while in the lower part of the rear opening, the substantially plate-shaped inner skirt 2 is attached to the frame 1 as a skirt by eg welded joints 3 . As a result, the strength advantages of the inner frame 1 as a stable casting can be combined with the weight advantages of the lightweight inner sheet metal covering skirt 2 at the lower portion of the rear opening.
附着在后背箱盖外表面并且其中可以安装例如一个汽车牌照凹槽7的外薄板4覆盖框架1和面向外侧的内裙板。框架1与外薄板4间的接合连接可通过例如图2所示的折边接缝5完成，如图2所示，其中外薄板4分另包过框架1，并且作为折边5被弯向内侧并固定在框架1上。The outer sheet 4, which is attached to the outer surface of the tailgate and in which eg a license plate recess 7 can be fitted, covers the frame 1 and the inner skirt facing outwards. The joining connection between the frame 1 and the outer sheet 4 can be accomplished, for example, by a hem seam 5 as shown in FIG. Inside and fixed on frame 1.
在内侧，由镁板形成的内裙板2通过焊缝3a被对焊在框架1上，并在内部覆盖了关于车辆内部的外薄板4下部。作为替代，该内裙板2也可由例如塑料面板形成，该塑料面板卡在外薄板4下部适宜造型的接收位置中并从而同时构成后背箱盖的内塑料镶板。On the inside, an inner skirt 2 formed from a magnesium sheet is butt-welded to the frame 1 via a weld seam 3 a and covers the lower part of the outer sheet 4 with respect to the vehicle interior on the inside. Alternatively, the inner skirt 2 can also be formed, for example, from a plastic panel which engages in a suitably shaped receiving position on the lower part of the outer sheet 4 and thus simultaneously forms the inner plastic paneling of the tailgate.
根据图4，在后背箱盖的一个变型中，内裙板2可通过易于制造的冲压铆接9简单连接在框架1上。这种冲压铆接连接特别适用于，因内裙板2和内框架1材料的材料结合而难以焊接或不可能焊接这两个构件的情况。According to FIG. 4 , in a variant of the tailgate, the inner skirt 2 can be simply connected to the frame 1 by punched riveting 9 which is easy to manufacture. This stamped riveting connection is particularly suitable when welding of the inner skirt 2 and inner frame 1 is difficult or impossible due to the material bonding of the two components.
