Definitions
- the present invention relates to a tool for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, and to a method for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin.
- Methods of this type for connecting material layers are used, for example, in the car industry and especially in the production of motor vehicles and components thereof of composite construction. For example, it may be necessary in this case to fasten plastics parts or add-on parts made of glass-fibre-reinforced plastic (GFRP) to body components made of steel sheet.
- GFRP glass-fibre-reinforced plastic
- connections of this type may be produced, for example, by mechanical riveting, wherein the rivet penetrates a first material layer and merely deforms a second material layer.
- spot welding is known, by way of which metal layers are melted in a locally small area and are welded to each other by the subsequent solidification.
- the use of a nail is known, said nail being driven through two material layers to be connected and thereby, by way of a form-fitting connection and also by way of a frictional connection via the dynamic effect at the head end of said nail, being able to produce a permanent connection between the material layers. In this case, the nail has relatively little resistance against being pulled out axially from the material layers.
- a method for joining two joining parts, in particular flat materials, of the type in question is known from DE 10 2004 025 492 A1.
- a joining element in particular a rivet
- the rivet bears against the second joining part, subjects the latter to a mechanical load, or, in accordance with one embodiment, even brings about a notch in the second joining part.
- current is then conducted into the contact points between the joining element and joining part and the latter are thereby welded.
- a joining force between the joining parts and the joining element is applied by two electrodes, between which the joining parts are clamped.
- a disadvantage of this known joining method is that the connection to the second joining part is not very stable and, in particular, only small shearing forces, if any at all, from the second joining part can be absorbed. Furthermore, only a small pressure can be exerted on the joining element by the tool used.
- an object of the invention to provide a tool and a method for joining at least two material layers, which tool and method are enhanced in this respect and in particular permit simple and secure joining of the material layers.
- a tool for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin comprising a driving-in device and a welding device, wherein the driving-in device is designed to drive the pin through the at least two material layers to be joined, and the welding device is designed so as, after the driving-in of the pin, to weld at least one first section of the pin to a metal material layer.
- the object is also achieved by a method for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, wherein, with a tool in accordance with the invention, the pin is driven through the at least two material layers to be joined and, after the driving-in of the pin, at least one first section of the pin is welded to a metal material layer.
- a tool is configured to join at least two material layers, of which at least one material layer is composed of a metal, the tool including at least one of: a driving-in device configured to drive a pin through the at least two material layers to be joined; and a welding device configured such that, after the driving-in of the pin, to weld at least one first section of the pin to the at least one material layer composed of the metal.
- a method for joining at least two material layers, of which at least one material layer is composed of a metal including at least one of the following: providing a tool including a driving-in device and a welding device; providing a fastener; driving the fastener using the drive-in device through the surface of the at least two material layers; and then welding the fastener using the welding device to the at least one metal material layer after driving the fastener.
- a method for joining at least two material layers, of which at least one material layer is composed of a metal including at least one of the following: pre-stressing the material layers; driving a fastener into the material layers; and then creating a welded connection at at least one contact point between the fastener and the metal material layer after driving the fastener by conducting a welding current through the fastener.
- the driving-in device of a tool in accordance with the invention is therefore designed to drive a pin through at least two material layers, in particular through all of the material layers, which are intended to be connected to one another.
- the driving through the material layers is understood as meaning that the tip of the pin penetrates the second material layer at least to an extent such that the tip comes to lie in the region of emergence from the second material layer. At least the tip of the pin, therefore, displaces the material of the second material layer as far as the region of emergence from said material layer. Owing to the fact that the pin is also driven into the second material layer, shearing forces from said material layer can be absorbed, and therefore a secure connection is ensured even under the action of lateral forces. For this purpose, the pin can penetrate the second material layer such that the tip of the pin already protrudes from the second material layer.
- the pin may also end shortly before emerging from the second material layer, and therefore the tip of the pin does not protrude out of the material layer.
- the driving-in device has, at least temporarily, to apply a correspondingly high force in order to drive the pin through both material layers.
- the tool in accordance with the invention has a welding device which, after the driving-in of the pin via the driving-in device, is capable of welding at least a first section of the pin to a metal material layer.
- the welding is generally achieved by way of resistance welding, but other methods, for example welding by way of inductive heating, are also conceivable.
- a tool in accordance with the invention is advantageously designed in such a manner that the welding device welds the at least first section of the pin, wherein the at least first section of the pin lies at a front end of the pin in the driving-in direction.
- the tool is designed in such a manner that the welding device conducts a welding current through the pin.
- the welding current may thereby cross non-metallic material layers by being guided along the pin which is in any case driven in.
- the tool is designed in such a manner that the welding device welds both ends of the pin to one metal material layer each. Material layers which are weldable to both ends of the pin are thereby welded by the driven-in pin such that reliable support is achieved at both ends of the pin.
- the driving-in device is designed in such a manner that the pin can be driven in pneumatically through the at least two material layers.
- the required force is achieved by comparatively simple means in order to drive the pin through the at least two material layers.
- the driving-in device part of the tool in accordance with the invention may be designed in this case in a similar manner to a known compressed-air nail driver.
- the latter for example, may also be designed electromechanically.
- a tool in accordance with the invention can advantageously be configured in such a manner that the material layers are prestressed against one another before the pin is driven in.
- the tool therefore, serves to execute the following steps: pre-stressing the material layers, driving in the pin and then welding the pin to the material layers. This is advantageous since the frictional connection between the material layers is enhanced by the step of pre-stressing.
- the tool is designed in such a manner that a pin which has a head at the rear and thereof in the driving-in direction is driven in by the driving-in device in such a manner that, after being driven in, the head bears against a first material layer in the driving-in direction.
- the tool can therefore drive in a pin which is designed as a nail, with a head. The head enhances the support of the pin or of the nail against a first penetrated material layer such that this end of the pin is readily fixed even without welding.
- the invention also relates to a method for connecting at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, wherein, with a tool in accordance with the invention, the pin is driven through the at least two material layers to be connected and, after the driving-in of the pin, at least one first section of the pin is welded to a metal material layer.
- At least one of the material layers which is joined in a method in accordance with the invention to at least one further material layer consists of a plastic or a fibre-plastic composite, such as, for example, glass-fibre-reinforced plastic (GFRP).

Abstract
A tool configured to join at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin. The tool includes a driving-in device which drives the pin through the at least two material layers to be joined, and a welding device which, after the driving-in of the pin, welds at least one first section of the pin to the at least one metal material layer.
Description
- The present application claims priority under 35 U.S.C. §119 to German Patent Application No. DE 10 2011 117 962.7 (filed on Nov. 7, 2011), which is hereby incorporated by reference in its entirety.
- The present invention relates to a tool for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, and to a method for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin.
- Methods of this type for connecting material layers are used, for example, in the car industry and especially in the production of motor vehicles and components thereof of composite construction. For example, it may be necessary in this case to fasten plastics parts or add-on parts made of glass-fibre-reinforced plastic (GFRP) to body components made of steel sheet.
- As is known, connections of this type may be produced, for example, by mechanical riveting, wherein the rivet penetrates a first material layer and merely deforms a second material layer. Furthermore, in order to join metal material layers, spot welding is known, by way of which metal layers are melted in a locally small area and are welded to each other by the subsequent solidification. Furthermore, the use of a nail is known, said nail being driven through two material layers to be connected and thereby, by way of a form-fitting connection and also by way of a frictional connection via the dynamic effect at the head end of said nail, being able to produce a permanent connection between the material layers. In this case, the nail has relatively little resistance against being pulled out axially from the material layers.
- A method for joining two joining parts, in particular flat materials, of the type in question is known from
DE 10 2004 025 492 A1. In this method, a joining element, in particular a rivet, is driven through one of the joining parts. The rivet bears against the second joining part, subjects the latter to a mechanical load, or, in accordance with one embodiment, even brings about a notch in the second joining part. In a subsequent welding process, current is then conducted into the contact points between the joining element and joining part and the latter are thereby welded. For this purpose, use is advantageously made of conventional welding tongues. - Furthermore, a joining force between the joining parts and the joining element is applied by two electrodes, between which the joining parts are clamped. A disadvantage of this known joining method is that the connection to the second joining part is not very stable and, in particular, only small shearing forces, if any at all, from the second joining part can be absorbed. Furthermore, only a small pressure can be exerted on the joining element by the tool used.
- It is, therefore, an object of the invention to provide a tool and a method for joining at least two material layers, which tool and method are enhanced in this respect and in particular permit simple and secure joining of the material layers.
- The object is achieved by a tool for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, comprising a driving-in device and a welding device, wherein the driving-in device is designed to drive the pin through the at least two material layers to be joined, and the welding device is designed so as, after the driving-in of the pin, to weld at least one first section of the pin to a metal material layer.
- The object is also achieved by a method for joining at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, wherein, with a tool in accordance with the invention, the pin is driven through the at least two material layers to be joined and, after the driving-in of the pin, at least one first section of the pin is welded to a metal material layer.
- In accordance with embodiments, a tool is configured to join at least two material layers, of which at least one material layer is composed of a metal, the tool including at least one of: a driving-in device configured to drive a pin through the at least two material layers to be joined; and a welding device configured such that, after the driving-in of the pin, to weld at least one first section of the pin to the at least one material layer composed of the metal.
- In accordance with embodiments, provided is a method for joining at least two material layers, of which at least one material layer is composed of a metal, the method including at least one of the following: providing a tool including a driving-in device and a welding device; providing a fastener; driving the fastener using the drive-in device through the surface of the at least two material layers; and then welding the fastener using the welding device to the at least one metal material layer after driving the fastener.
- In accordance with embodiments, provided is a method for joining at least two material layers, of which at least one material layer is composed of a metal, the method including at least one of the following: pre-stressing the material layers; driving a fastener into the material layers; and then creating a welded connection at at least one contact point between the fastener and the metal material layer after driving the fastener by conducting a welding current through the fastener.
- The driving-in device of a tool in accordance with the invention is therefore designed to drive a pin through at least two material layers, in particular through all of the material layers, which are intended to be connected to one another. In this case, the driving through the material layers is understood as meaning that the tip of the pin penetrates the second material layer at least to an extent such that the tip comes to lie in the region of emergence from the second material layer. At least the tip of the pin, therefore, displaces the material of the second material layer as far as the region of emergence from said material layer. Owing to the fact that the pin is also driven into the second material layer, shearing forces from said material layer can be absorbed, and therefore a secure connection is ensured even under the action of lateral forces. For this purpose, the pin can penetrate the second material layer such that the tip of the pin already protrudes from the second material layer.
- The pin may also end shortly before emerging from the second material layer, and therefore the tip of the pin does not protrude out of the material layer. For this purpose, the driving-in device has, at least temporarily, to apply a correspondingly high force in order to drive the pin through both material layers. In addition, the tool in accordance with the invention has a welding device which, after the driving-in of the pin via the driving-in device, is capable of welding at least a first section of the pin to a metal material layer. The welding is generally achieved by way of resistance welding, but other methods, for example welding by way of inductive heating, are also conceivable.
- Developments of the invention are indicated in the dependent claims, the description and the attached drawings.
- A tool in accordance with the invention is advantageously designed in such a manner that the welding device welds the at least first section of the pin, wherein the at least first section of the pin lies at a front end of the pin in the driving-in direction. As a result, irrespective of the type of connection of the rear pin end, the frequently pointed front part of the pin, which is driven through the material layers, is in any case welded to a metal material layer and thereby securely fixed.
- In accordance with a preferred embodiment of the invention, the tool is designed in such a manner that the welding device conducts a welding current through the pin. The welding current may thereby cross non-metallic material layers by being guided along the pin which is in any case driven in.
- In a further embodiment, the tool is designed in such a manner that the welding device welds both ends of the pin to one metal material layer each. Material layers which are weldable to both ends of the pin are thereby welded by the driven-in pin such that reliable support is achieved at both ends of the pin.
- It is particularly advantageous for a tool in accordance with the invention if the driving-in device is designed in such a manner that the pin can be driven in pneumatically through the at least two material layers. In this manner, the required force is achieved by comparatively simple means in order to drive the pin through the at least two material layers. The driving-in device part of the tool in accordance with the invention may be designed in this case in a similar manner to a known compressed-air nail driver. As an alternative to the pneumatic design of the driving-in device, the latter, for example, may also be designed electromechanically.
- A tool in accordance with the invention can advantageously be configured in such a manner that the material layers are prestressed against one another before the pin is driven in. The tool, therefore, serves to execute the following steps: pre-stressing the material layers, driving in the pin and then welding the pin to the material layers. This is advantageous since the frictional connection between the material layers is enhanced by the step of pre-stressing.
- It is also advantageous if the tool is designed in such a manner that a pin which has a head at the rear and thereof in the driving-in direction is driven in by the driving-in device in such a manner that, after being driven in, the head bears against a first material layer in the driving-in direction. In this embodiment, the tool can therefore drive in a pin which is designed as a nail, with a head. The head enhances the support of the pin or of the nail against a first penetrated material layer such that this end of the pin is readily fixed even without welding.
- The invention also relates to a method for connecting at least two material layers, of which at least one material layer is in the form of a metal material layer, by a pin, wherein, with a tool in accordance with the invention, the pin is driven through the at least two material layers to be connected and, after the driving-in of the pin, at least one first section of the pin is welded to a metal material layer.
- For example, at least one of the material layers which is joined in a method in accordance with the invention to at least one further material layer consists of a plastic or a fibre-plastic composite, such as, for example, glass-fibre-reinforced plastic (GFRP). The method in accordance with the invention is particularly advantageous, for example, in the fastening of GFRP material to body components.
- In one embodiment of the method, at least one metal material layer is formed by a metal auxiliary element. This is advantageous in particular whenever an otherwise outer material layer cannot be welded. In this case, a sheet-metal disc, or else a sheet-metal strip, can be used as an auxiliary element in order to permit welding of the pin to said auxiliary element and, by means of this welded connection, to securely fix the further material layers.

Thelayer 1 is formed by the metal body, and thelayer 4 which is arranged on the opposite side of the material layers corresponds to a metal add-on part, for example, a sheet-metal strip. Theintermediary layers weldable layers - All of the material layers 1, 2, 3 and 4 are intended to be permanently connected to one another by a
pin 5 and are not yet connected inFIG. 1 . A tool in accordance with the invention includes the driving-indevice 6 and awelding device 7 having an upper electrode and lower electrode are schematically illustrated.

By pressurization, such as, for example, pneumatically, of the driving-inpiston 6 using a sufficient force, in a direction towards thepin 5, causes thepin 5 to be driven through the surface of all of the material layers 1, 2, 3 and 4 in the position illustrated. Of thewelding device 7, theelectrodes 7 are illustrated as an essential element. - After the
pin 5 is driven into the material layers 1, 2, 3 and 4, theelectrodes 7 are placed against theouter material layers welding device 7 through thepin 5 such that a high temperature is formed at the contact points between thepin 5 and theweldable layers components pin 5. - The tool illustrated, therefore, has a driving-in
device 6 which functions, for example, in a similar manner to a known compressed-air nail driver, and awelding device 7 which functions, for example, in a similar manner to known welding tongs. -

The tool is placed onto the material layers 1, 2, 3 and 4. - As illustrated in
FIG. 2 b, the material layers 1, 2, 3 and 4 are then prestressed by closing the electrodes of thewelding device 7, which is designed, for example, in the manner of tongs. - As illustrated in
FIG. 2 c, thepin 5 is then driven pneumatically into the material layers 1, 2, 3 and 4 by the driving-in piston of the driving-indevice 6. The state in which thepin 5 is already driven in through all fourmaterial layers pin 5 protrudes from the surface of theoutermost material layer 1 and theoutermost material layer 4. - As illustrated in
FIG. 2 d, the driving-inpiston 6 is then manipulated in a rearward direction away from the material layers 1, 2, 3 and 4, and a welding current conducted by thewelding device 7 through the electrodes and thepin 5 such that acurrent flux 11 is conducted from one tong half of the outermost electrode via thepin 5 to the other tong half of the outermost electrode corresponding to the arrows illustrated inFIG. 2 d. This results in the welds at the contact points between thematerial layers pin 5, the welds being illustrated inFIGS. 2 e and 2 f by the weldedconnections 12. - As illustrated in
FIG. 2 e, the tool is manipulated rearward again and can then be advanced to the next joining point. - As illustrated in
FIG. 2 f, the material layers 1, 2, 3 and 4 are joined after the treatment, in which the weldedconnections 12 are formed between thepin 5 and the material layers 1 and 4, has ended. -
FIGS. 3 to 5 illustrate further use possibilities of the tool in accordance with the invention for joining components. InFIG. 3 , instead of a headless pin as illustrated inFIGS. 1-2 , apin 5 having ahead 10, i.e., a nail, is used. As illustrated and described inFIGS. 2 a-2 f, the nail is driven into the material layers 1, 2 and 3 by the tool and welded by the welding device (not illustrated inFIG. 3 ). Since, in this exemplary embodiment, only thelayer 1 is composed of a weldable material, a welded connection (not illustrated) is formed only between theoutermost layer 1 and thepin 5. Theoutermost plastics layer 3 is fixed via thenail head 10. - In a similar manner, a nail with a
head 10 is also used inFIG. 4 as thepin 5 for producing the connection between thematerial layers flat components auxiliary element 9 composed of, for example, a weldable metal material such as a sheet-metal disc, is therefore placed onto the joining point. The further connection is undertaken in the manner described above with reference toFIGS. 2 a-2 f using the tool in accordance with the invention. The connection is, therefore, produced at a first end by a welded connection between thepin 5 andauxiliary element 9 and at a second end of thepin 5 by the frictional connection between thehead 10 and theoutermost material layer 3. - In another alternative embodiment illustrated in
FIG. 5 , apin 5 is used without a head. For this purpose, twoauxiliary elements 9 composed of, for example, a weldable metal material such as a sheet-metal disc, are used as weldable material layers. By use of the tool in accordance with the invention, two welded connections are formed, namely a welded connection in each case between thepin 5 and each of the twoauxiliary elements 9. - The tool and method in accordance with embodiments of the invention is therefore advantageous in permitting a secure connection between at least two material layers, using the tool with a driving-in device and a welding device, whereby a pin is driven in through at least two material layers and is subsequently welded to at least one metal material layer.
