Description

TECHNICAL FOR PRODUCING AN OBJECT AND CONNECTING ARRANGEMENT THEREFOR}

The present invention provides a first component and providing a second component, the first component and the second component arranged up and down such that the connecting surface of the first component is in contact with the connecting surface of the second component. And a step of connecting the first component and the second component.

The invention furthermore relates to a connecting device for forming a connection between a first component and a second component.

Composite articles are understood to be articles having undercuts or recesses in at least two directions arranged at angles greater than 0 ° with respect to each other. Metal articles of this kind can only be produced in a metal-cutting process, for example by re-clamping in a tool. When such a composite article is made of plastic material, it is necessary to regularly provide an injection mold having a complex slide device, thereby increasing the manufacturing cost. It is known to manufacture articles of complex form by connecting at least first and second components to each other, which components have a less complex form individually and can therefore be manufactured significantly more cost-effectively.

Such a connection can be formed substantially pointed, linear or planar. The materials of the components may be the same or different. In addition, when articles manufactured in this way are used as intended, the components may be exposed to different loads, in particular external loads.

With respect to this background, it is an object of the present invention to specify an improved method or connecting device for producing a complicated type of article.

This object is firstly realized by a method for producing a composite shaped article of the above-mentioned type, wherein the first and second components are connected to each other at two or more connection points and in a direction parallel to the connection surface. There is provided a tolerance-compensation device that compensates for a tolerance.

In addition, the object is achieved in particular by means of a connection device made according to this method.

The manufacturing method according to the invention is based on the connection of the first and second components to each other at a plurality of connection points. By providing a tolerance-compensating device it is possible to absorb or offset the stresses generated in the case of different heating of the components, for example. Such different heating can be caused, for example, by the components being manufactured from different materials. However, such different heating may also depend on the intended use of the article, for example if one side is exposed to a heat source (eg the sun) and the other side is not exposed.

Absorption or compensation of this stress can significantly increase the durability of the connection formed between the first component and the second component.

The composite article may be a vehicle body component such as, for example, a door element.

Accordingly, this object is fully realized.

In the method according to the invention, it is particularly preferred that the components are made of plastics material, the step of providing the components incorporating a plurality of thermally conductive connecting elements into the first component and / or the second component. Wherein connecting the first and second components may in each case be simultaneous or sequential of the connecting elements to form a thermoplastic welded connection between the first component and the second component at a plurality of connection points. Phosphorus heating step.

In this embodiment, the two plastic components can be connected to each other in a simple manner to produce a plastic article of a composite form. Integration of the auxiliary connection elements can be carried out, for example, during the injection-molding manufacturing process for each component. Furthermore, in this case it is possible to provide a thermoplastic welded connection when the connection point is only accessible from one side, ie when one of the two components is only accessible from the side. As a result, the manufacturing process can be significantly simplified.

Particularly preferably in this case the auxiliary connecting element is heated in an inductive manner from one side.

In general, induction heating from two sides is also possible. In addition, other types of heating are also possible by applying a current or the like.

However, induction heating has the advantage that the auxiliary connection element integrated in the first and / or second component can preferably be heated without having to contact them.

Further preferably, a recess is provided in at least one component in the region between the two connection points, the recess providing tolerance compensation in a direction parallel to the connection surface.

In this embodiment, the tolerance-compensating device can be formed in a relatively simple manner, in particular by providing a recess between the connection points. Different expansions of the components can be tolerated through these recesses.

In this case, two recesses are provided in at least one component, particularly preferably in the region of at least one connection point, the recesses being in a direction parallel to the connection line and / or parallel to the connection surface. It is provided on the opposite side of one connection point in the connection line connecting the connection points to provide tolerance compensation in the direction.

In this embodiment, the recess is provided on each side of the connection point, whereby the stress generated in the direction parallel to the connection line can be effectively absorbed.

Furthermore, according to a further embodiment, preferably connecting the first and second components comprises engaging the first component of one or more connecting elements projecting with respect to the connecting surface of the first component and The second component comprises a recess, the component when the component is arranged up and down by moving a connecting element through the recess when the component is arranged up and down and attaching a clip element to the connecting element. Connecting the elements to each other.

 This embodiment is contemplated as a separate invention without considering the provision of a tolerance-compensating device whether the components are connected to each other at one or more connection points.

However, in the suitable shape of the connecting element and the recess on the other hand, this type of connection can provide tolerance compensation in a direction parallel to the connection surface. In addition, depending on the shape of the component, the connecting element and the clip element in this shape, tolerance compensation can also be performed transversely with respect to the connecting surface.

In this embodiment, the components can be connected to each other in a relatively simple manner even when the components are made from different materials.

Particularly preferably the first component and the connecting element are made of the same material. In the case of a metal, the first component and the connecting element can then be adhesively bonded or welded to one another, for example.

However, particularly preferably, the first component and the connecting element are made of plastic material.

In this case, preferably the thermally conductive auxiliary connecting element is integrated into the connecting element and / or the first component, and the step of connecting the connecting element and the first component is thermoplastic welded between the connecting element and the first component. Heating the connection element to form a connection.

As described above, the production of thermoplastic welded connections can be carried out, for example, by heating the auxiliary connection elements inductively from one side.

In general, preferably in the manufacture of a thermoplastic welded connection of the type described above, the welded connection is produced immediately after the process for manufacturing the connection element and / or the first and / or second component, and the first And / or the second component and / or the connecting element has a temperature higher than the ambient temperature.

In this embodiment, residual heat of this type can be used accordingly so that the thermoplastic welded connection can be carried out more quickly and effectively.

In the case of the connection device according to the invention, particularly preferably, the connection device has a hollow cylindrical part extending from the flange part on the outer periphery, on which the thermally conductive auxiliary connection element is integrated and on which the radially projecting head part is formed. A connecting element having a shank portion.

In this embodiment, the head portion can be provided for fastening the clip element, for example.

Accordingly, the shank portion is formed in a hollow-cylindrical shape and the auxiliary connecting element integrated in the flange portion can be heated by inserting an energy source into the hollow-cylindrical shank portion. In addition, the cavity can have the fastening function of the clip element on the connecting element.

Thus, the connection device preferably comprises a clip element having a U-shaped shoulder portion and a base portion which are connected through an edge portion such that a head receptacle for the head portion of the connection element is formed between the shoulder portion and the base portion.

In this embodiment, the clip element can be formed such that the clip element can be pressed onto the connecting element substantially parallel to the connecting surface and / or in the transverse direction with respect to the coupling axis.

Each connection can thus be formed by a simple assembly step.

Particularly preferably in this case, the latching tongue is formed on the base part and protrudes relative to the base part in the direction of the shoulder part.

The clip element can be easily connected to the connecting element in a latching manner by this latching tongue.

Especially preferably, in this case the latching tongue is engaged in the hollow part of the shank part of the connecting element.

In this embodiment, the head portion received in the head receptacle and provided on the outer periphery of the shank portion may be provided as a means for fixing in a direction parallel to the engagement axis. The latching tongue can be provided as a fastening means for preventing the clip element from unintentional pulling from the connecting element.

In addition, the shoulder portion has at least one clamping riser on the outer side spaced from the base portion for engaging the component in a clamping manner.

The provision of such clamping rises makes it possible to manufacture connecting elements and / or clip elements and / or components with greater tolerances. Accordingly, the clamping riser can fasten the second component arranged between the first component and the clip element in a clamping manner, and the components can be firmly fixed to each other.

According to a further preferred embodiment, the clip element has one or more elastic tongues which can be elastically deflected in a direction opposite to the pushing-on direction in which the clip element can be pressed onto the connecting element.

In this embodiment, the elastic tongue can be joined to the joint at the end position on the connecting element, whereby a better fixation of the individual elements of the connecting device can be realized.

The auxiliary connecting element described above may preferably be in the form of a perforated sheet and is preferably in the form of a circular perforated sheet. Instead of a single heated element, such as a perforated sheet, it is also possible to introduce metal particles, such as auxiliary connecting elements, into each component.

The connection between the connection element and the components and / or between the components can be formed in an automated manner, for example by a robot. In this case, the connecting element can be supplied automatically.

Furthermore the clip element can also be assembled on the connecting element in an automated manner. Thermoplastic welding with an auxiliary connecting element can be carried out according to an access accessible from one side. In contrast to so-called fakir welding, damage to the components during the joining process can be prevented in this case. Furthermore, the tool for heating the auxiliary connection element does not have to have the same contour as the surface contour of the connection element and / or the component. Thermoplastic welding can also be performed by a tool with some destructive contours without a heating plate, for example hot-plate welding.

In addition, for example, high pressure is not necessary in the case of vibration welding.

Since the thermoplastic welding according to the invention can preferably be carried out by means of a uniformly heated auxiliary connecting element, the geometrical tolerances of the components to be connected can be compensated. The auxiliary connection element can be adapted to the magnetic field of the induction heating tool (induction machine) so that the heating can be carried out as uniformly as possible.

The weight of the auxiliary connecting element is relatively small, so that the amount of energy to be introduced can be reduced.

As a result of the lower energy input, the torsion phenomenon can be reduced, thus affecting the opposite side in the case of the visible part.

In the case of thermoformed parts (thermoforming prior to heating the parts), the welding system can be inserted directly into the tool and the joining can be carried out during the cooling process or simultaneously with the molding in the tool.

The components can be arranged independently of the dimensions associated with the tool. A sufficiently planar surface is required to connect the components to each other.

In order to minimize tolerances, full integration of auxiliary connecting elements to the positioning features attached to the coupling system and / or one or more components to be joined is preferred.

The tolerance compensation device can also be implemented by configuring the connection zone in a suitable manner. Tolerance compensation can in this case be two-dimensional or three-dimensional.

The components can preferably be connected without further adhesive and / or connecting frame. It is also possible to attach fastening elements to pressure sensitive components such as sandwich materials (roof liners, honeycomb sandwich structures, hollow bodies, blow-molded parts).

The above-described features can be used in each case in combination as well as in other combinations or as such without departing from the scope of the present invention.

1 to 3 show a first embodiment of a composite object with reference numeral 10.

The article 10 has an undercut 12 in the undercut direction 14. In addition, the article 10 has a depression 16 in a recess direction 18 transverse to the undercut direction 14.

In order to manufacture the article 10, the first component 20 and the second component 22 are connected to each other. The first component 20 has, for example, an undercut 12. As a result, the first component 20 can be manufactured relatively simply. The second component itself may have a recess 16. In this case, the recess 16 is formed by the first component 20 and the second component 22.

The first component 20 has a bottom plate 24 and a wall plate 26 extending transverse to the bottom plate. The second component 22 has a lower panel 22 and a wall panel 30 extending transverse to the lower panel. The upper panel 32 also extends from the wall panel 30, and an undercut 12 is formed between the upper panel 32 and the lower panel 28.

The first component 20 has a first connecting surface 34 formed on the bottom plate 24. The second component 22 has a second connecting surface 36 formed on the side of the lower panel 28 facing in the direction away from the upper panel 32.

In order to connect the components 20, 22, two connecting surfaces 34, 36 are positioned up and down. In addition, the first and second components 20, 22 are connected to each other at a plurality of connection points. In this case, the first connection point 40 and the second connection point 42 are shown by way of example in FIG. 1.

The connection points 40, 42 are arranged along a virtual connection line 44 having a connection line direction 46. The connecting line direction 46 is, for example, oriented transverse to both the undercut direction 14 and the recess direction 18.

In order to form the connection points 40, 42 the first component 20 and the second component 22 run transverse to the connecting line direction 46 and preferably the undercut direction 14 and / or It runs transverse to the recess direction 18, the joining direction being shown at 48 and connected to each other in the joining direction. The connection of the components 20, 22 in the form of dots along the connecting line 44 can cause stress upon different heating of the first component 20 and the second component 22. To at least reduce or prevent these stresses, a tolerance-compensating device 50 is provided. In the present case, the tolerance-compensating device 50 is preferably formed by a plurality of recesses arranged on the connecting line 44, in particular in each case preferably one or more recesses are each connecting point. Provided between 40 and 42. In this case, the first recess 52 and the second recess 54 are shown. The recess may be formed, for example, in the second component 22.

The side of the first component 20 spaced apart from the second component 22 (eg, the surface of the lower plate 24 facing the first connecting surface 34) may be in the form of a visible surface. have. Thus, at least non-continuous recesses are provided in the first component 20.

In addition, the connection points 40, 42 are manufactured such that the tool for manufacturing the connection points 40, 42 is applied from only one side, specifically from the side of the second component 22. This can prevent the tool from operating in the area of the visible surface.

Preferably, the connection points 40, 42 are also manufactured such that no joints need to be applied from the side of the visible surface.

Connection points 40, 42 may be manufactured according to the material of component 20, 22, for example by joining or similar portions. However, particularly preferably the components 20, 22 are each made from thermoplastics and the connection points 40, 42 are made using auxiliary connecting elements. The auxiliary connection elements 56 are each formed by thermally conductive elements. Metal particles may be inserted into the material of one of the components. Preferably, the auxiliary connecting element 56 is a small metal plate or metal sheet. For example, as shown in FIG. 3, it is preferably formed in a circular shape and may be in the form of an annular element. These annular elements may furthermore be provided with holes in order to realize a firmer connection to the component to which the auxiliary connecting element is integrated.

1 to 3, components 20 and 22 are in the form of thermoplastic components, for example, produced by an injection molding process. Since the components 20 and 22 are each of a relatively simple form, these elements can be manufactured in a relatively simple injection mold (eg without a slide).

In the embodiment of FIGS. 1-3, the auxiliary connecting elements 56 are each integrated into the second component 22 at the connection point. In FIG. 3, the auxiliary connecting elements 56 are each integrated such that they end at the same height as the second connecting surface 36. However, also shown in FIG. 3 is one auxiliary connecting element 56 ′ fully integrated into the second component 22, which may not be visible outward.

3 further shows that it is possible to provide a positioning aid 57 on the surface of the second component 22 opposite the second connecting surface 36, in which the auxiliary connecting element is arranged in a second manner. Integrated into component 22, for example, the positioning aid 57 may be constructed of a circular imprint or a circular impression or the like.

The article 10 is made such that the connecting surfaces 34, 36 are arranged up and down. Thereafter, a tool for heating the auxiliary connecting element 56 is applied to the surface of the second component 22 opposite the second connecting surface 36 (eg, the position of the positioning aid 57). in). Subsequently, the auxiliary connecting element 56 arranged underneath is heated, for example by induction. As a result, the thermoplastic material of the second component 22 and the adjacent thermoplastic material of the first component 20 begin to melt so that the melt is bonded to each other and in this way the first component 20 and the second component. Dotted thermoplastic welded joints between the 22 are made. This way of making the connection points can be performed sequentially on the individual connection points 40, 42, etc., or can be performed simultaneously when a suitable tool is provided. Furthermore, it is preferably preferred that the connection is made immediately, for example after the second component 22 has been produced (injection-molding process or the like). In this variant, the remaining heat of the second component 22 (and / or Formulation 1 component 20) may be used to allow lower energy input to make the welded connection.

When the first and second components 20, 22 are connected to each other in this way, the connecting device 58 is formed by a plurality of connecting points.

4 to 11 show further embodiments of the connecting device 58 ′ according to the invention.

The connecting device 58 ′ shown in these figures (see eg FIGS. 5 and 11) includes a connecting element 60 for each connection point as shown in FIG. 4. The connecting element 60 has a flange portion 62, which can be formed, for example, as a flat cylindrical portion. From the flange portion 62 an shank portion 66 having a diameter smaller than the flange portion 62 extends. A head portion 64 having a larger diameter than the flange portion 62 and a larger diameter than the shank portion is formed at the upper end of the shank portion 66. The shank portion 66 and the head portion 64 are in the form of a hollow portion such that the cylindrical cavity 70 is formed in the connecting element 60, and the cavity 70 is the connecting element 60 as shown in FIG. 5. It is in the form of a blind cavity which is open on the opposite side of the and is closed by the flange part 62.

As in the embodiment described above, an auxiliary connecting element 56 is integrated into the flange portion 62, which auxiliary circular element is a circular annular sheet made of metal particles, preferably induction-heatable material. It can be made of sheet metal elements such as metal elements.

As shown in FIG. 5, the connecting element 60 is specifically coupled to the first connecting surface 34 of the first component 20 by a thermoplastic welding method. The first component 20 and the connecting element 60 are in this case preferably made of thermoplastics.

5 shows that an axial recess 72 can be provided radially within the auxiliary connecting element 56 on the connecting side of the flange portion 62. This recess 72 may be preferred for forming a connection between the connecting element 60 and the first component 20 as described, for example, in document WO 2010/057599 Al. The flange portion 62 of the connecting element 60 may in this case be formed in a manner similar to or the same as the flange portion of the connecting element shown in that document. In this regard, the present disclosure is intended as the focus of the present application and reference is made to the disclosure of this document.

The connecting device 58 ′ shown in FIG. 5 also houses the clip element 74. The clip element 74 is shown in detail in FIGS. 6 to 10 and has a base portion 76 and a shoulder portion 78 axially spaced from the base portion. The shoulder portion 78 is formed in the shank receptacle 79 with respect to the shank portion 66 and is formed in a U shape. The base portion 76 and the U-shaped shoulder portion 78 are connected to each other by an edge portion 80 that is U-shaped in plan view. A head receptacle 81 for receiving the head portion 64 of the connecting element 60 is formed in the U-shaped region between the base portion 76 and the shoulder portion 78.

The latching tongue 82 is formed approximately centered on the base portion 76.

In order to connect the clip element 74 to the connecting element 60, the clip element 74 is pressed in a pushing-on direction 86 onto the head portion 64 of the connecting element 60. The pushing-on direction 86 runs in the transverse direction, in particular perpendicular to the longitudinal axis of the engagement direction 48 or the connecting device 58 '.

As shown in FIG. 5, after pressing the head portion 64 is received in the head receptacle 81 and the base portion 76 is seated on the upper side of the head portion 64, and the shoulder portion 78 is On its underside it is engaged behind the head portion 64. In addition, the latching tongue 82 is provided with a ramp portion 84 and extends into the area of the head receptacle 84. The ramp portion 84 is formed such that the latching tongue 82 deflects with respect to the plane of the base portion 76 under the influence of the head portion 64 when the clip element 74 is pressed. As soon as the clip element 74 is pressed further sufficiently onto the head portion 64, the head portion 64 abuts against the rear end of the edge portion 80 in the pushing-on direction 86 (left in FIG. 5). ), The latching tongue 82 returns back to its starting position and in this case is engaged behind the inner wall of the cavity 70 as shown in FIG. 5. In this way the clip part is fastened to the connecting element 60 in both the axial direction (parallel to the engagement direction 48) and the radial direction (parallel to the pushing-on direction 86).

In this case a gap 85 is provided between the first connection surface 34 and the lower side of the clip element 74, preferably the gap being higher than the height of the flange portion 62. The second component 22 can be accommodated in the space defined by this spacing 85, for which the second component preferably has a recess for receiving the flange portion 62.

In particular, two elastic tongues 88 are formed on the base portion 76 as shown in FIGS. 7 and 8. The elastic tongue 88 is designed to be radially deflected, for example, by bonding against the wall panel 30 of the second component 22 as shown in FIG. 1.

For example, the elastic tongue 88 is radially oriented such that the latching tongue 82 is always in contact with the wall of the cavity 70 and consequently prevents accidental bounce of the latching tongue 82. Can be provided to support the clip element 74.

Furthermore, as shown in particular in FIGS. 6, 9 and 10, the clip element 74 has at least one click on its side, ie on the side of the shoulder portion 78 facing away from the base portion 76. Ping rises 92. In this case two clamping rises 92 are provided which extend in a direction parallel to the pushing-on direction 86 and are formed in a substantially lip-shaped manner. The clamping rise 92 is formed such that the rise rises in a conical shape opposite to the pushing-on direction 86. During pushing on, the second component 22 accommodated in the gap 85 is fixed by the clamping riser 92 and clamped therein.

As further shown in FIG. 11, the second component 22 has a recess 94 having a diameter larger than the outer diameter of the flange portion 62.

In this way, tolerance compensation can be implemented in a direction parallel to the connecting surfaces 34, 36. In view of the crimping rise 92, tolerance compensation can be implemented in this way substantially in the transverse direction.
