Description

The The invention relates to a rivet, in particular a rivet nut and a rivet pin, in a mold cavity. In addition, the invention relates a method for producing a rivet part in a mold cavity.

rivet parts are understood below in the general sense and are not only on embodiments such as rivet nuts or Rivet pins limited.

rivet parts are typically used to mechanically couple two or more parts connect to each other, with about a connecting part in a corresponding trained receiving the rivet part engages and a mechanical Connection between both guaranteed (alternatively, of course also the rivet part in a corresponding receptacle of the connecting part intervention). Usually, such connecting parts include a connecting portion, for example a threaded portion, which in a corresponding mating connection section, for example a Gegengewindeabschnitt, which in the recording of the rivet part is provided, can be inserted and thus a fixed mechanical connection of connecting part and rivet allows.

Such mechanical connections are already known from the prior art. Thus, for example, reveals DE 24 42 759 A1 a connecting element consisting of a commercially available screw and a one-piece or multi-part sleeve nut, wherein the sleeve nut carries at its head facing the screw head an approach with key surfaces. At the part facing away from the screw head, the sleeve nut has the usual mother thread and in the intermediate middle sleeve part is so shaped with structural means that when tightening the screw while holding the same or the middle sleeve part (s) are so strong that the After tightening resulting largest outer diameter of the sleeve center piece is about 1.5 to 2 times larger than the original outer diameter. In this case, a front or internal toothing is provided, so that the individual sleeve nut parts are secured against mutual rotation.

Furthermore, for example, from the DD 216 075 A1 a rivet nut with anti-rotation device for positive impressions of threaded fasteners to sheet metal parts known. Here, the rivet nut consists of an embossed conical hexagon, as well as a conically formed outer diameter and a conical from the outer diameter also at an angle of 10 ° inwards to the hexagon extending plant surface.

These Known from the prior art rivet parts, are for used a screw connection between a screw with corresponding external thread and a thin To allow sheet metal position. Due to the provision of in the thin sheet metal position rivet rivet parts, it does not need the cutting of an internal thread in, for example, a receiving opening the thin sheet metal layer. Just because of the small thickness of such Sheet metal layers providing an internal thread in such Receiving opening is often technically impossible, or could not guarantee the required Rivet parts are often the only way a solid screw connection with such thin sheet metal layers to enable.

Around but a fixed screw connection between a connecting part with a screw outer thread and the rivet with To realize a screw internal thread, the connecting part be screwed into the rivet accordingly. This requirement However, alone requires that the connecting part on the one hand rotatable must be able to handle, and on the other hand, that the Connecting part with so much force can be applied to a mechanical screwing, or inserting it into the To reach the rivet part.

such Prerequisites, however, may be constructional Grounds of numerous connecting parts and already riveted Rivet parts are not met. It's not like that, for example rarely the case that due to an appropriate shaping of the Connecting parts of this no suitable attack surface for power transmission. The interaction with a Tool for inserting the connecting part in the rivet part can therefore impossible or only using special tools to be possible. Furthermore, it is often the case that the described connection between connecting part and receiving the Rivet part by too little space not in technical meaningful way.

As from the above descriptions of those known in the art Riveted parts, there is therefore a technical need to to propose a rivet part in a mold cavity, which indicated the Disadvantages of the devices of the prior art avoids. Especially It is the object of the present invention to provide a component to suggest connectable rivet part, which allows a connecting part as well then insert into the rivet part and connect with this to be able to, if the connecting part itself not rotatable can be handled.

These Task is by a rivet in a mold cavity according to claim 1, 22, 27 and 29, as well as by a method for producing a Rivet part in a mold cavity according to claim 23 solved.

Especially the object is achieved by a rivet part, in particular a rivet nut, in a mold cavity, comprising: a rivet part with a base body and a cylindrically symmetric and extending in extension of the main body Shank, which has a substantially smooth outer wall of a first diameter and of a cylindrically symmetric, limited terminal edge of a second diameter becomes; a mold cavity in a surface portion of a mechanical component containing at least one constricted, in particular cylindrically symmetric area on one of the surface the component facing side, whose effective diameter corresponds to a third diameter and the one by a defined first tolerance greater than the first diameter of the shaft, as well as one in relation to the surface the component underlying area, wherein the rivet part in the mold cavity is held rotatable by the shaft from the surface of the component is introduced into the component and the terminal Finishing edge expanded in the underlying area of the component is such that the second diameter of the cylindrically symmetrical terminal edge is substantially larger than the third diameter the narrowed area of the component.

Farther the problem is solved by a rivet part, in particular a rivet nut, in a mold cavity, which is as follows Obtaining a rivet part with a base body as well a cylindrically symmetric and in extension of the body extending shaft, which has a substantially smooth outer wall of a first diameter and of a cylindrically symmetric, limited terminal edge of a second diameter becomes; Providing a mechanical component with a mold cavity in a surface section that has at least one narrowed, in particular cylindrically symmetric area on one of the surface the component facing side, whose effective diameter corresponds to a third diameter and the one by a defined first tolerance greater than the first diameter of the shaft, as well as one in relation to the surface comprising the component below it; Introduce of the shank from the surface of the component into the component with the terminal termination edge in the underlying area the component is arranged; Widening of the terminal Finishing edge in the underlying area with a riveting tool with a substantially cylindrically symmetrical tool part such that the second diameter of the cylindrically symmetrical end edge is substantially larger than the third diameter of the narrowed area, and that the rivet part rotatable in the mold cavity is held.

henceforth The task is also solved by a rivet in a mold cavity, which has the following features: a rivet part with a main body as well as a cylindrically symmetric and extending in extension of the body shaft, the one substantially smooth outer wall of a first Diameter and of a cylindrically symmetric, terminal End edge of a second diameter is limited, which Anchoring means; a mold cavity in a surface section a mechanical component, the at least one constricted, in particular cylindrically symmetric area on one of the surface the component facing side, whose effective diameter corresponds to a third diameter, and that by a defined first Tolerance greater than the first diameter of the shaft is, as well as with respect to the surface of the component underlying area, with the rivet part in the mold cavity is held rotatable by the shaft from the surface of the component is introduced into the component and the anchoring means of terminal end edge in the area below of the component with corresponding counter-anchoring means in engagement are brought, wherein the mating anchoring means an extension substantially parallel to the extent of the surface portion in a manner substantially larger than the third diameter of the narrowed portion of the component.

Furthermore, the object is also achieved by a rivet part, in particular a rivet pin, in a mold recess, which has the following features: a rivet part with a base body and a cylindrically symmetrical shaft extending in extension of the main body, which has a substantially smooth outer wall of a first diameter and is bounded by a cylindrically symmetrical, terminal end edge of a second diameter, wherein the base body and / or the shaft has a receiving region in which a pin-shaped fastening device is provided; a mold cavity in a surface portion of a mechanical component having at least one narrowed, in particular cylindrically symmetric region on a side facing the surface of the component whose effective diameter corresponds to a third diameter, and which is greater than the first diameter of the shaft by a defined first tolerance , As well as with respect to the surface of the component underlying area, wherein the rivet part is held rotatably in the mold cavity by the Shaft is inserted from the surface of the component in the component and the terminal end edge is widened in the underlying portion of the component, so that the second diameter of the cylindrically symmetrical end edge is substantially greater than the third diameter of the narrowed portion of the component.

moreover the object is achieved by a method for producing a rivet part, in particular a rivet nut, dissolved in a mold cavity, which comprises the following steps: providing a rivet part with a base body and a cylindrically symmetric and extending in extension of the main body Shank, which has a substantially smooth outer wall of a of first diameter and of a cylindrically symmetric limited terminal edge of a second diameter becomes; Providing a mechanical component with a mold cavity in a surface section that is at least one constricted in particular cylindrically symmetric area on one of the surface the component facing side, whose effective diameter corresponds to a third diameter, and that by a defined first Tolerance greater than the first diameter D1 of the Shank is, as well as with respect to the surface of the Component comprises underlying area; Introduction of Shaft from the surface of the component into the component, with the terminal termination edge in the underlying Area of the component is arranged; Expansion of the terminal end edge in the underlying area with a riveting tool with substantially cylinder-symmetrical tool part such that the second diameter the cylindrically symmetrical end edge substantially larger is considered the third diameter of the narrowed area, and that the rivet part is held rotatably in the mold cavity.

One essential point of the invention is that the rivet part is held rotatably in the mold cavity. Here is the shaft of the rivet part in such a way in the mold cavity of a mechanical component Inserted a rotation around a typically of the Longitudinal axis of symmetry of the cylindrically symmetrical shaft corresponding axis can be executed. The in relation on the shaft terminal end edge is so far widened that the rivet part does not leave the mold cavity without Expenditure of a great force can be removed. Should Now another connection part with the rivet part or a corresponding Recording of the rivet part are connected, so the connection, if this typically a rotating movement of the connecting part regularly required, in this case achieved be that the connecting part with the rivet part or the recording the rivet part according to frictional contact is brought and rotates the rivet itself in the mold cavity is, with the connecting part is inserted. Should this Connection by means of a screw thread or a bayonet lock be achieved, so it requires only the mechanical rotation the rivet part in the mold cavity and not the connecting part itself, to a screwing of the connecting part in the rivet part or a to achieve the intended recording.

In an advantageous embodiment of the present invention can be provided that the shank of the rivet part in the narrowed, in particular cylindrically symmetric region of the mold cavity positive fit intervenes. The positive engagement ensures on the one hand a largely uniform Rotation of the rivet part in the mold cavity, on the other hand can also a wobble of the rivet part in the mold cavity, even if this is not rotated, be avoided. Consequently, the mechanical Stability of the connection of rivet part and mold cavity elevated. It should also be noted that a form-fitting Do not interfere with the presence of the first tolerance between the at least a narrowed area on the surface of the component and contradicts the first diameter of the shaft. Interlocking In the present case, this merely means the engagement of the shaft in the at least one narrowed area on the surface of the Component so that, despite mechanically stable retaining compound From rivet and forming recess a largely unhindered rotation the rivet part can be made in the mold cavity.

In another embodiment of the present invention can be provided that the component made of plastic, in particular Bakelite, or a glass fiber or carbon fiber reinforced Material, or of metal, in particular of steel. such Materials ensure a mechanically stable hold the rivet part in the mold cavity while the wear characteristics, even with harsh rotation of the rivet part in the mold cavity, about a relatively long period of time can be guaranteed. Furthermore, these materials have a relatively low friction quotient on which ensures that a rotation of the rivet part takes place in the mold recess largely friction.

In a particularly advantageous embodiment of the present invention can be provided that the mold recess is a recess, in particular a hole in a plate-shaped component. Regardless of the thickness of this plate-shaped component, consequently, a connection between the rivet part received in the recess formed as a recess, in particular as a bore, and a connecting part not further developed can be ensured. Moreover, that is Mold recess in a technically easy to control and conventional method produced.

In a further preferred embodiment of the rivet part in a recess can be provided that the in relation on the surface of the component under the narrowed, in particular cylindrically symmetric area lying an effective area fourth diameter larger than that effective third diameter of the narrowed, in particular cylindrically symmetric Range is, with the cylindrically symmetrical end edge of the rivet part engages in this area. The under the narrowed, in particular cylindrically symmetric region lying area is typically with the narrowed area over a continuous, shaped Wall connected. According to the embodiments of the Walls of the under the narrowed, in particular cylindrically symmetrical Area lying this area can expand to define in which of the cylindrically symmetrical end edge the rivet part is arranged substantially. Typical embodiments the walls define, for example, bevels, curves or gradations. The walls can also be shaped like this be that they are the widening of the cylindrically symmetric terminal edge Rebuild the rivet, without this but in constant mechanical interaction must be. Likewise this under the narrowed, in particular cylindrically symmetric area lying area together with the cylindrically symmetrical end edge of the rivet part two mutually sliding surfaces of revolution define. Consequently, the under-constricted, in particular cylindrically symmetric area lying area the mechanical stability of the composite of rivet part and mold cavity as well as the synchronization to increase even further during rotation of the rivet part.

In a further embodiment may be provided be that the cylindrically symmetrical end edge of the rivet part in the surface of the plate-shaped member facing away from the surface. Consequently, can the rivet part are then also provided as a connecting element, if on the surface of the plate-shaped Particle facing surface restrictions in With regard to the space available there. In addition, reduced the avoidance of a projection of the rivet part on the Surface facing away from the plate-shaped component Area the risk of injury to a user, which with the surface portions of the opposite surface comes into contact.

moreover can be provided that under the narrowed, in particular cylindrically symmetric region lying a skew or Has rounding with respect to the surface of the component. By providing a skew or a rounding in under the narrowed, in particular cylindrically symmetric area lying area can be about the trained in this area mechanical rubbing surfaces for friction with the cylindrically symmetric, terminal end edge of the rivet part formed in such a way be that the total friction upon rotation of the rivet part in the mold cavity while maintaining a high overall stability of the compound can be guaranteed from rivet and mold recess.

In a further preferred embodiment of the present invention Invention, the terminal end edge in the under the narrowed, in particular cylindrically symmetric area lying area of the component by a riveting tool with substantially cylindrically symmetrical Tool part weggesteuert and / or be expanded force controlled. During the path-controlled expansion, the riveting tool measures with the essentially cylindrically symmetrical tool part the distance, with which the tool part is typically along the symmetry longitudinal axis of the cylindrically symmetrical shaft in these under application of the cylindrically symmetrical terminal end edge with a force is introduced to widen the end edge. In the force-controlled expansion is not the corresponding Distance of the tool part but the time course of the force considered. But there are also combinations of a force or path control conceivable. In particular, in a basic path control of Propulsion then be adjusted if a predetermined limit for the force, this limit being either constant or may be path-dependent, exceeded becomes. Alternatively, the force control can also be travel-dependent be.

As a result of the path control, the degree of widening of the cylindrically symmetrical, terminal end edge can be dimensioned, which on the one hand determines the stability of the connection of the rivet part to the shaped depression, and on the other hand defines the rotational properties of the cylindrically symmetrical shaft in the mold recess. Thus, for example, in the case of insufficient widening of the terminal edge, the rivet part in the mold recess does not allow a sufficiently mechanically stable hold, and may also permit a mechanical slipping of the rivet part out of the mold cavity. In contrast, a correspondingly too widened end edge can affect the rotational ability of the rivet part in the mold cavity. As an alternative to the path-controlled widening of the terminal edge of the rivet part, a time-controlled method can be used in which at approximately predefined pressure on the cylindrically symmetrical terminal end edge of the rivet part by the tool part over a predetermined defined period of time, the degree of expansion of the Final margin.

In a further embodiment of the present invention Invention may be the terminal termination edge with the area of the device with the effective fourth diameter be widened in such a way that the cylindrically symmetrical end edge substantially form-fitting in the underlying with respect to the surface of the component Area of the component while maintaining a second tolerance intervenes. The positive engagement is ensured on the one hand a good hold of the rivet part in the mold cavity, on the other hand, the provision of maximum large sliding surfaces upon rotation of the rivet part in the mold cavity. With that transfers the load acting on the rivet part in the mold cavity, or force on a maximum sliding area between the outer wall of the shaft and the terminal Finishing edge on the one hand and the at least one narrowed area the component and the underlying area of the component on the other. Maximizing the total sliding surface during rotation of the Rivet part in the mold cavity thus allows a good distribution the forces acting on the rivet part and on the other hand a little or even wear of the mold well material as well as the rivet part material. It should be noted here that the rivet part is typically made of metal, wherein Hardened metals, such as hardened steels or helical steels are particularly well suited.

In a further preferred embodiment of the present invention Invention may be the outer wall of the shaft and / or the Form recess of the component to be surface-treated, to an improved rotation of the rivet part in the mold cavity of the To enable component. The surface treatment able to include a hardening of the material, which a reduction of static friction and sliding friction effect upon rotation of the rivet part in the mold cavity. on the other hand The surface treatment can also be smoothed out the outer wall of the shaft and / or the walls of the mold cavity of the component, which also the friction losses during rotation can reduce the rivet part in the mold cavity. Accordingly, the surface treatment can also allow a rotation of the rivet part in the mold cavity, too if on this great external forces act.

In a particularly preferred embodiment of the rivet part in a mold cavity, the main body of the rivet part have a screw internal thread. The screw internal thread can according to the execution also on the cylindrically symmetric shaft or sections of the cylindrically symmetric Shank extend. Consequently, a screw connection between a connecting part with external screw thread and the Schraubeninnengewinde of the rivet part are made. alternative to a screw connection is also a bayonet and a plug or screw connection possible. Consequently, the basic body of the rivet part, or also partial sections of the shaft, corresponding Threaded connections or counter-threaded connections on. In general, all are according to the embodiment industry-standard connection systems, which induce the connection require a rotational movement, claimed herein.

In In another embodiment, the base body of the rivet part to the transition region between the base body and the shaft facing the surface of the component have first contact surface. This bearing surface On the one hand ensures the stable connection of rivet and mold cavity, and prevents unintentional performance of the rivet part through the mold cavity towards the surface side facing away from the component. On the other hand, the first bearing surface also upon rotation of the rivet part in the mold cavity a sliding surface together with sections of the surface of the component and can consequently become uniform Contribute rotation of the rivet part in the mold cavity.

In a further embodiment of the rivet part in a mold cavity, the first bearing surface of the Main body of the rivet part surface treated to improve rotation of the rivet part in the mold cavity allow the component. The surface treatment again does not extend exclusively to the first bearing surface of the main body of the rivet part, but may also affect sections of the surface of the component. The surface treatment can turn into a cure claimed in the rotation of the rivet in the mold cavity Gleitflächenabschnitte exist, or even in a smoothing these designated surface sections. Also a surface coating the surfaces subjected to frictional forces during rotation can be provided.

In another embodiment of the present invention, the main body of the rivet part may have a non-rotationally symmetrical outer edge. The provision of a rotationally symmetrical outer edge of the base body of the rivet part allows, for example, the rotation of the rivet part by means of tools which have a machining section adapted to the non-rotationally symmetrical outer edge. For example, a base body with an elliptical outer edge with a machining tool turning about to establish a connection between the rivet part and another verbin not further described Be achieved molding part when the machining tool has an inversely elliptical shaped machining section. Consequently, it is possible, the rivet part, which may have substantially any outer edge shapes, according to the inventive sense also by means of other tools (processing tools) to rotate in the mold cavity.

To a further preferred embodiment of the present invention Invention, the main body of the rivet part a hexagonal have molded outer edge. Consequently, the processing becomes or rotation of the rivet part in the mold cavity by means of commercial and industry standard hex key of the corresponding Sizes possible.

In a further embodiment of the rivet part in a mold cavity For example, the main body of the rivet part may be one from the surface facing away from the second support surface as abutment surface for have a tool. This tool can be both a machining tool be for rotation or rotation of the rivet part in the mold cavity, as well as a riveting tool, for widening the end edge and Production of a retaining connection between rivet part and mold recess. The provision of a second bearing surface as an abutment surface facilitates the adjustment or non-positive contact of the tool with respect to the main body of the rivet nut. Processing by the tool is therefore not only facilitated but also increased in terms of its precision.

In a further embodiment of the rivet part in a mold cavity, the wall thickness of the shank can be less than 1 mm, in particular between 0.2 mm and 0.8 mm. Such a wall thickness ensures both a solid mechanical hold of the Rivet part in the mold cavity, as well as the easy processing of the rivet part, for example with a hydraulic riveting tool.

Farther can be provided that the terminal end edge the rivet part has a chamfering / rounding provided on the outside, which the insertion of the rivet part in the mold cavity facilitates the component. Accordingly, also at the insertion of high volumes of rivet parts this in the mold cavities of one or more components without the Occurrence of mechanical pass problems are inserted. Providing one on the outside of the terminal End edge of the rivet part provided bevel / rounding is particularly advantageous if the diameter of the cylindrically symmetric Finishing edge largely with the narrowing of the narrowed area the mold cavity coincides.

moreover is provided in one embodiment, that the rivet part an electrically conductive coating to increase the Conductivity of the rivet on predetermined surface sections having. Consequently, the contact resistance is reduced when the predetermined surface portions for power line be brought into contact with other conductor sections. The others Conductor sections can also be the area section be the mechanical component itself. Accordingly, a electrical power connection between the electrically conductive surface portion and the rivet part via electrical contact points on the body, on Shank or generated at the end edge of the rivet. Become the contact points on the rivet part to increase the conductivity with a good electrically conductive coating, for example provided with a noble metal or noble metal alloy coatings, results in a better conduction behavior with lower power loss. Such coatings may also preferably be used in conjunction with be provided a Verliersicherung the rivet.

In a further embodiment of the rivet part in a mold cavity is also provided that the rivet at least one comprises electrically non-conductive or electrically poorly conductive material, to flashovers over predetermined Prevent surface sections. Such non-conductive or poorly conductive materials are, for example, plastics or semi-metals, in particular cordsed aluminum. alternative this can also be superficial coatings the rivet part of non-conductive or poorly conductive materials be provided. In a particularly preferred embodiment For example, the rivet part includes a threaded insert which is for prevention of voltage flashovers an electrically non-conductive or electrically poorly conducting material.

henceforth the rivet part in a cavity can also be characterized by that the cylindrically symmetrical shaft and / or the terminal End edge, at least one slot and / or at least one Notch. This results in a reduction of occurring Joining forces when inserting the rivet part in the mold cavity.

In another embodiment of a rivet part in a mold recess, it is provided that the counter-anchoring means are connected to the anchoring means by clamping, by means of a screw connection, adhesively or by means of a welded connection. In particular, the connection of anchoring means and counter anchoring means may be a detachable or non-detachable connection. By providing industry standard verbin Applications, such as those described above, a simple and inexpensive rivet part can be made in a mold cavity.

henceforth it is possible that the pin-shaped fastening device firmly connected in the receiving area with the rivet, in particular is pressed. This can already be done before inserting the Rivet part in the mold cavity a reliable connection of rivet and pin-shaped fastening device be achieved without further work steps necessary afterwards become. The connection can be done by screwing, pressing, welding or by other industry standard procedures. The pin-shaped fastener is in the connection for inserting the rivet part in the mold cavity to the other Processing available, with the pin-shaped Fasteners together with the rivet part in the mold cavity is kept rotatable. In particular, the pin-shaped Fastener a screw or a screw-like Medium.

alternative can also be provided that the pin-shaped fastening device in the receiving area with the rivet part by an adhesive or clamping retaining fuse is connected. Such a retention may in the case about that the pin-shaped fastener a screw is to be designed as Ausdrehsicherung, which prevents that one in the rivet part already at a previous time inserted screw in subsequent processing steps can not be unintentionally unscrewed from the rivet. A Retaining security as well as the Ausdrehsicherung in particular as a plastic coating, for example, the annular shape or partially annular around the pin-shaped Fastening device is arranged to be executed, the one clamping attachment of the pin-shaped fastening device ensured in the rivet part. The attachment can after Successful insertion of the rivet in the mold cavity by spending a corresponding torque on the pin-shaped Fixing device to be solved when the rivet part, in relation to the pin-shaped fastening device is held immovable. After that stands the pin-shaped fastening device available for further use.

moreover may also be in a continuation of the process of preparation a rivet part in a mold cavity the terminal End edge in the region of the component by the riveting tool with driven away substantially cylindrically symmetrical tool part and / or force-controlled expansion. The way-controlled like the force-controlled expansion allows, as already outlined above, the controlled widening of the terminal edge of the rivet part, allowing both a solid mounting of the rivet part can be guaranteed in the mold cavity, as well a free or good rotatability of the rivet part in the mold cavity possible is.

In another embodiment of the method of manufacture the rivet part in a mold cavity is provided that the rivet part by means of a joining tool reliable in the mold cavity is used. The joining tool can in this case a joining tool be with stop collar, which is an even more precise and safe insertion of the rivet part in the mold cavity allowed.

In Another embodiment of the method for production the rivet part in a mold cavity is provided that before insertion of the shaft in the component of the shaft and / or the end edge be provided with an anti-rotation, the rotatability the rivet part in the mold cavity temporarily inhibited. A Such rotation can also be designed as captive be, which is a loss of the rivet part of the mold cavity even before the widening of the end edge avoids. In addition, can the anti-rotation also after the expansion advantageous if, for example, the temporary suppression of rotatability a simplified insertion of other components in the Rivet or another use of the rivet causes. Becomes the rivet part at a later desired time with subjected to a corresponding torque, the rotation is solved or even completely destroyed, and the rotatability can be restored. Farther It is possible that by purposefully widening the end edge or the shaft controls the frequency of rotatability can be done by the expansion to the extent that the frictional force between the contact surfaces of the shaft and / or the end edge as well those of the Formvertiefung are just so great that a Rotate overcoming a predetermined contact frictional force is possible. By excessive However, the contact frictional force will widen so much that the rotatability can not be done.

Furthermore, possibly occurring friction forces between the end edge 14 and that of the deepening of the form 2 do not cause a rotation of the rivet part 1 in the mold cavity 2 prevented.

The rivet part according to the execution 1 still has a recording 19 in the main body 11 which is intended, a not further shown herein connecting part with the rivet part 1 connect to. The connection of rivet part 1 and the connecting part, not shown, preferably takes place by turning the rivet part 1 in the mold cavity 2 of the component 4 ,

2 shows an enlarged side sectional view through the first embodiment of the rivet according to the invention 1 in a mold cavity 2 as it already is from the 1b is known. Here are the individual geometric relationships of the rivet 1 as well as the component 4 with the mold cavity 2 explained in more detail. The main body 11 of the rivet part 1 points next to the recording already described 19 a first bearing surface 17 and a second bearing surface 18 on. Here is the first bearing surface 17 on the surface section 3 the surface 25 of the component 4 arranged. Depending on the arrangement of the rivet part 1 in the mold cavity 2 of the component 4 can be a direct mechanical contact of the first bearing surface 17 with the surface section 3 the surface 25 present or not. In the case of the presence of a surface contact, however, to ensure the rotation of the rivet part 1 in the mold cavity 2 be assured that the friction forces between the contact surfaces can be overcome by the forces imparted by the rotation. Moreover, prevents the first bearing surface 17 whose areal extent is greater than that in the representation of 2 shown areal extent of a cross section through the narrowed area 21 the shape recess 2 parallel to the surface section 3 , a falling through or slipping of the rivet part 1 in the area 23 of the component 4 , At the same time prevents the widening of the end edge 14 in that area 23 slipping of the rivet part 1 on the surface 25 facing side of the component 4 , Here, the substantially cylindrically symmetrical shaft 12 a smaller diameter D1 than the diameter D3 of the narrowed portion 21 the shape recess 2 , The difference in length between the diameter D3 of the narrowed area 21 and the diameter D1 of the shaft 12 results in a tolerance T1. The tolerance T1 is represented as half the difference of the diameter D3 and the diameter D1. The tolerance T1 essentially ensures the rotatability of the rivet part 1 in the narrowed area 21 the shape recess 2 ,

In comparison, the expanded end edge 14 , which also has cylinder symmetry, an effective diameter D2, which for securing the rivet part 1 in the narrowed area 21 the shape recess 2 must be greater than the diameter D3 of the narrowed area 21 the shape recess 2 , As effective diameter of the widened end edge 14 For example, the largest distance can be defined, between two corresponding ones and on the end edge 14 opposite points. Present in 2 became the effective diameter D2 of the flared terminal edge 14 as the average of the distance of all on the outer surface of the end edge 14 lying points which are arranged diametrically opposite, defined. The definition of the effective diameter D2 of the widened end edge 14 However, this is largely arbitrary, as long as it is ensured that due to the widening of the end edge of the rivet part 1 in the narrowed area 21 the shape recess 2 can be held.

According to execution, the basic body 11 of the rivet part 1 an outer edge 16 on which the basic form of the basic body 11 in view of the rivet part 1 (not shown here). Thus, for example, by appropriate shaping of the outer edge 16 and applying at least a portion of this outer edge with a rotating force by a not further shown herein tool the rivet part 1 in the narrowed area 21 the shape recess 2 be rotated. Here is the second bearing surface 18 sure that the tool not shown here does not match the surface 25 of the surface section 3 of the component 4 got in contact.

3 represents a further embodiment of the rivet part 1 in a mold cavity 2 in a side sectional view, wherein the rivet part 1 essentially the rivet part 1 the first embodiment in the 1a . 1b and 2 equivalent. Only the component 4 differs in the present case from the components shown above 4 , The component 4 in the presentation of the 3 stands out one through the narrowed area 21 the shape recess 2 out, which on the surface 25 facing side of the component 4 is arranged. Below this narrowed area 21 the shape recess 2 on the other hand is an expanded area 27 in the area below 23 by a skew 32 in the material of the component 4 arranged. The expanded area 27 as well as the narrowed area 21 are aligned concentrically with each other. The skew 32 of the expanded area 27 This corresponds largely to the skew, which by the widened end edge 14 in that area 23 is fixed. Here are also partial areas of the end edge 14 on the side of the arrangement of rivet part in a mold cavity 2 , which lies on the side, that of the surface 25 opposite surface 26 is facing. Alternatively, however, it would also be conceivable that the end edge 14 is formed such that even after the expansion of all sections of the end edge 14 within the range 23 are arranged.

4 shows a comparison with the embodiment according to 3 largely similar embodiment of the rivet 1 in a mold cavity 2 , but the closing edge 14 is not expanded as much as in the embodiment according to 3 , Also defined herein defines the diameter D1 of the shaft 12 , which again is essentially cylindrically symmetrical, and the diameter D3 of the narrowed region 21 the shape recess 2 , which is also essentially cylindrically symmetrical in the present case, the tolerance T1. Compared to the embodiments according to 1a . 1b and 2 of the rivet part 1 in a forming recess, however, in this case the tolerance T1 is lower, which in the present case has a more dimensionally stable seat (holder) of the rivet part 1 in the mold cavity 2 guaranteed.

In addition, half the difference in turn defines the substantially cylindrically symmetric diameter D2 of the terminal edge 14 and the diameter D4 of the expanded area 27 the shape recess 2 a second tolerance T2 representing the outer walls of the terminal edge 14 as well as the walls of the widened area 27 spaced. Hereby let's define the diameter of the widened area 27 the shape recess 2 on the definition of the diameter D2 of the end edge 14 referenced above. Depending on the definition of the diameters D2 and D4, the tolerance T2 may assume a minimum value, a maximum value or a value lying between these two extreme points. The presently illustrated tolerance T2 is therefore to be understood as an example only. Although in the present case due to the size ratios of the tolerance T1 and the tolerance T2, the tolerance T2 for both the stability of the holder of the rivet 1 in the mold cavity 2 as well as for the rotational behavior of the rivet part 1 in the mold cavity 2 In comparison with the tolerance T1, it does not have such a significant meaning, so this meaning may be different if there is another ratio of the tolerance T1 to the tolerance T2.

In 5 is another embodiment of the rivet part 1 in a mold cavity 2 a component 4 shown, wherein the main body 11 of the rivet part 1 instead of a recording 19 (not shown here) now a screw internal thread 15 having. The screw internal thread 15 , which is shown here only symbolically by dashed lines, is in the body 11 and on the present not further designated inner walls of the shaft 12 arranged. According to the present embodiment, the internal screw thread is sufficient 15 from the transition area 30 between the main body 11 and the shaft 12 to about half of the length of the shaft 2 parallel to the axis of rotation of the rivet part 1 , However, it is at the discretion of the skilled person, different sections of the inner walls of both the body 11 as well as the shaft 12 to be provided with a screw internal thread. The present extent of the internal screw thread is therefore to be understood as an example only.

Furthermore, in contrast to the embodiments of the rivet part 1 in the mold cavity 2 according to the 3 and 4 is here the expanded area 27 of the area 23 of the component 4 not by a skew 32 but by a rounding 32 Are defined.

In 6 will be another embodiment of the rivet part 1 in a mold cavity 2 illustrated, wherein the embodiment of the rivet part 1 in comparison to the embodiment of the rivet part 1 in 5 the screw internal thread 15 from the main body 11 only up to a floor area 28 is sufficient, which is largely perpendicular to the walls of the shaft 12 lies. Here it is again at the discretion and at the discretion of the skilled person, the floor area 28 both in the main body 11 as well as in the shaft 12 provided. The provision of a floor area 28 proves to be advantageous if, for example, must be ensured that one in the screw internal thread 15 introduced connecting part not to the remote area 26 facing side to be performed.

Furthermore, in comparison to the embodiment of the rivet part 1 in a mold cavity 2 according to 5 here has the finishing edge 14 a rounding off 31 on which is on the outside wall of the end edge 14 is provided. The rounding off 31 facilitates the insertion of the rivet part 1 in the mold cavity 2 especially if the effective diameter D2 of the terminal edge 14 and the effective diameter D3 of the narrowed portion 21 the shape recess 2 have only a relatively small tolerance T1.

In 7 are a total of four different embodiments of the rivet in a mold cavity 2 in a top view of the main body 11 of the rivet part 1 shown. Thus, in the present case, the main body 11 of the rivet part 1 a second bearing surface 18 on which is formed circularly symmetrical. The on the second bearing surface 18 arranged portion of the body 11 has an outer edge 16 which typically has walls perpendicular to that through the second support surface 18 defined level stands. The walls of the outer edge 16 have in the illustrated plan on different geometric arrangements. In the present case, a hexagonal geometry (top left), an octagonal geometry (top right), a five-edged geometry (bottom left) and a star-shaped geometry (bottom right) of the walls of the outer edge are shown as examples only 16 , Because of this deviating from a rotationally symmetrical geometry arrangement of the walls of the outer edge 16 of the basic body 11 it is conceivable for rotation of the rivet part 1 in the mold cavity 2 to use a tool having a correspondingly shaped fitting area, and by means of which the rivet part 1 can be acted upon by a torque. Such tools can be in the simplest case size-precise hex wrench (for rotation of the embodiment of the rivet 1 according to the left upper illustration), but can also be any other special tools.

It should also be noted that in the presently illustrated embodiments of the rivet part 1 just a shot 19 in the basic bodies 11 is provided, which is formed for connection to a connecting part not further shown. This recording 19 can, as it is obvious to a person skilled in the art, also be replaced by a screw thread, a bayonet connection, a plug connection or else a screw plug connection.

8th shows two possible embodiments of the component 4 with a mold cavity 2 from the side of the surface 25 wherein the cross-section of the mold cavity shown 2 may have both circular (left view) and a deviating from the circular shape (right representation). To ensure the rotation of a rivet part 1 (not shown here) in one of the illustrated mold cavities 2 is only crucial that the mold cavities 2 treads 29 have, which are formed at least partially circular or curved. This is the case in the right-hand view of the deepening of form 2 in 8th a deepening of form 2 represented, which a total of four treads 29 whose two-dimensional extensions to each other in one of the right in the form of recess 2 comparable cross-sectional shape result.

9a and 9b show two different embodiments of a rivet 1 as can be used to make a device according to the invention. This in 9a illustrated rivet part 1 corresponds to the in the 1a . 1b . 2 . 3 and 4 rivet parts shown 1 , where the end edge 14 in comparison to the shaft 12 not expanded. The rivet part 1 according to 9b largely corresponds to the embodiment of the rivet part 1 in 9a , however, have the outer wall 13 of the shaft 12 two ringer lifts 33 on, which have a semicircular cross-section in the illustrated lateral sectional view. Is the shaft 12 as well as the end edge 14 formed substantially cylindrically symmetric, so surround the Ringer surveys 33 the outer wall 13 of the shaft 12 in a ring-like structure. The semicircular shape of a ring lift 33 in cross-section is to be understood only as an example and can be replaced by any other geometric shape. The only important thing is that the two Ringerhebungen 33 performing structures after insertion of the rivet part 1 in the mold cavity 2 and widening the end edge 14 the surfaces (outer walls) of the two Ringerhebungen 33 an improved rotation of the rivet part 1 in the mold cavity 2 due to reduced frictional forces. It should also be taken into account that the arrangement of the two Ringerhebungen 33 the stability of the holder of the rivet part 1 in the mold cavity 2 should not significantly worsen.

In the 10a and 10b is a method of making a rivet part 1 in a mold cavity 2 illustrated using a riveting tool 40 , The in the 1a and 1b illustrated embodiments of the rivet 1 in a mold cavity 2 corresponding embodiments in the 10a and 10b represent two temporally consecutive steps of a riveting process, by means of which the finishing edge 14 of the rivet part 1 is widened, ie the rivet part 1 riveted. This shows 10a a state of in the mold cavity 2 of the component 4 inserted rivet part 1 even before the widening of the end edge 14 , When inserted shaft 12 as well as inserted border 14 of the rivet part 1 in the mold cavity 2 of the component 4 is in this case a counter-tool 42 in the recording 19 of the basic body 11 of the rivet part 1 introduced, which typi scherweise stationary is arranged. Instead of introduction to the recording 19 can be the counter-tool 42 also be shaped so that it with the second bearing surface 18 of the basic body 11 is in frictional contact. In a corresponding extension to the direction of a rivet axis NA is located on the of the main body 11 of the rivet part 1 remote side of the rivet 1 a tool part 41 which is also of the riveting tool 40 is included. In this case, the rivet axis NA corresponds in the simplest case to the axis of rotation (rotation axis) of the rivet part 1 in the mold cavity 2 of the component 4 , The tool part 41 is on its close-out 14 of the rivet part 1 side facing shaped so that it is when force in the end edge 14 of the rivet part 1 engages and can expand this under force. The widening of the end edge 14 is in 10b shown. This was the tool part 41 towards the counter tool 42 of the riveting tool 40 moved along the rivet axis NA, leaving the end edge 14 was widened. The widening of the end edge 14 is sufficient to remove the rivet part 1 without further ado from the component 4 to prevent.

The riveting tool shown here 40 is typically a path-controlled and / or force-controlled hydraulic press acting as a counter-tool 42 as well as tool part 41 has corresponding inserts. The path control and a force control ensures a controlled widening of the end edge 14 , so that optimal retention of the rivet part 1 in the mold cavity 2 of the component 4 while ensuring good rotatability is guaranteed. The hydraulic riveting tool measures 40 the distance over which the tool part 41 as well as the counter tool 42 be moved against each other. If a movement has taken place over a predetermined distance, there is no further application of force (pressurization) of the tool part 41 instead of. Alternatively to a path-controlled and / or force-controlled widening of the end edge 14 is also a timed expansion of the end edge 14 possible.

11 shows a side sectional view through a further embodiment of the rivet 1 in a mold cavity 2 with anchoring agents 51 and counter-anchoring means 52 for holding the rivet part 1 in the mold cavity 2 , The main body 11 of the rivet part 1 is located above the surface section 3 of the component 4 arranged. On the side of the surface 25 opposite surface 26 are anchoring means 51 and counter-anchoring means 52 provided, which unintentional removal of the rivet part 1 from the mold cavity 2 avoid. The anchoring means 51 are designed as an annular thickening with a partially circular cross-section, which the course of the shaft 12 follows and in the present case also the end edge 14 equivalent. The finishing edge 14 however, it may take any suitable further form. The anchoring means 51 engage in a corresponding inversely annular groove executed a Gegenverankerungsmittels 52 a, and are held in this by means of clamping forces. The counter-anchoring means 52 are also designed annularly with a substantially rectangular cross-section. The extent of the counter-anchoring means 52 along the opposite surface 26 is dimensioned such that the effective diameter is greater than the effective diameter D3 of the narrowed region 21 the shape recess 2 is.

The present embodiment is only to be understood as an example. The connection of anchoring agents 51 and counter-anchors 52 can be implemented releasably by means of a clamping connection, a Chp connection, a plug connection, a screw connection or any other industry-standard releasable connection. Alternatively, the compound of anchoring agents 51 and counter-anchors 52 but also be designed as a non-detachable welded joint, adhesive bond, solder joint, press connection or otherwise industrial, non-releasable connection.

12 shows a side sectional view through a further embodiment of a rivet 1 with a means of a retaining fuse 62 attached pin-shaped fastener 61 ie a rivet pin. The embodiment of the rivet part 1 In the present case, this largely corresponds to the embodiment of the rivet part 1 in 11 , however, is not yet in a mold cavity 2 a component 4 introduced. The recording area 60 (functionally identical to the recording 19 ) has a pin-shaped fastener 61 on, which can represent, for example, a connecting screw. So that the pin-shaped fastener 61 not from the rivet part 1 can be removed accidentally, such as during transport before insertion into the mold cavity 2 the construction part 4 , this is by means of the retaining fuse 62 in the recording 60 of the rivet part 1 held and temporarily fixed. The retaining fuse 62 can in this case as a plastic layer, in particular as a plastic ring or as a plastic coating in the recording 60 , Which is a clamping attachment of the pin-shaped fastening means 61 guaranteed. The attachment takes place until the pin-shaped fastener 61 when subjected to a torque against the rivet part 1 is rotated, and as a result of this rotational movement, the retaining fuse 62 solved and / or even completely destroyed.

13a FIG. 4 illustrates a side sectional view through a first embodiment of a rivet part. FIG 1 with a pin-shaped fastener 61 Here is the pin-shaped fastener 61 with the rivet part 1 undetachably firmly connected, wherein the rivet part in a mold cavity 2 a component 4 is introduced and by widening the end edge 14 in the mold cavity 2 is kept rotatable. Consequently, the pin-shaped fastener is also 61 kept rotatable and can be processed or used in further steps. The connection of rivet part 1 and the pin-shaped attachment means 61 is effected in the pressing region P by material flow of the contact surfaces into each other. Alternative to this, or in addition to this, can be a screwing, a ferrule, a welding or otherwise common industrial connection for connecting rivet 1 and the pin-shaped connecting part 61 to get voted.

13b FIG. 4 illustrates a side sectional view through a second embodiment of a rivet part. FIG 1 with a pin-shaped fastener 61 The second embodiment corresponds to a modification of the geometry of the rivet part 1 and pin-shaped fasteners 61 the first embodiment in 13a , In particular, rivet part 1 and the pin-shaped fastener 61 by pressing under flow of material in the pressing region P permanently connected to each other inseparably. Alternatively, rivet part 1 and fasteners 61 also be formed in one piece.

14 shows a side sectional view through a further embodiment of the rivet 1 in a mold cavity 2 a component designed as a contact lug 4 ; In addition, in the present case also schematically a tool part 41 a riveting tool 40 shown, which is the end edge 14 widens and so the rivet part 1 for rotatable holder in the mold cavity 2 with the component 4 riveted. The component 4 is presently designed as a contact tab, as used for example in a motor vehicle for fastening an electrical conductor to a battery or to threaded bolts in distribution and / or control boxes. At the contact lug 4 a current conductor connection S is attached, which for further power line of the energized component 4 is available. The voltage supply can be effected via a voltage source, whose at least one pole is designed to, with the receiving area 60 of the rivet part 1 electrically contacted and connected. Preferably, the pole is designed as a pin-shaped fastening device with external thread, wherein the external thread with a in the receiving area 60 of the rivet part 1 arranged internal thread can be screwed. The screwed contact surfaces in this case allow a flow of current from the pin-shaped fastening device to the conductor connection S via the component 4 , For undisturbed power line must have a good surface contact between the rivet 1 and the component 4 be ensured, wherein the rotatability of the rivet part by tightening can also be limited.

15 shows a front perspective view of another embodiment of the rivet 1 in a mold cavity 3 a component designed as a contact lug 4 (left half of the figure) and an embodiment which is known from the prior art, for comparison (right half of the picture). Both embodiments differ only by the attachment of both parts to the component 4 , The embodiment known from the prior art has instead of a rotatable rivet part 1 a rotatable flange nut 70 whose rotation is ensured by the fact that several retaining claws 71 made of formed material of the component 4 the flange nut 70 rotatable on the component 4 holders. The holding claws 71 are around the flange nut 70 arranged so that removing the flange nut 70 only by removing or reshaping the retaining claws 71 it is possible.

In comparison, the execution rivet part 1 into the component 4 on the surface section 3 riveted rotatable and insoluble. Like the embodiment in FIG 14 Also, the present embodiment relates to a component 4 , which is formed as a contact tab. At the present contact tab is also a cable holder 72 provided, in which a power cable, for example, by clamping or adhesive can be firmly held.

The above embodiments make it clear again that the rivet part according to the invention 1 can be provided in a variety of applications, with different thread sizes and in various forms.

In addition, it should be noted that by inserting further elements, in particular by inserting toothed pulleys, between the rivet part 1 and to the power line provided device parts, the electrical contact between the contact surfaces of this improved power line can be effected. These can ensure an improved production of an electrical contact by indentations in the materials of the contact surfaces.

In addition, other, not described in detail above elements with additional securing effect in an internal thread of the rivet 1 be provided to prevent slipping or unintentional release of a part which at least partially into the internal thread of the rivet 1 is introduced.

Furthermore, also disc devices under the body can 11 of the rivet part 1 be provided, which are shaped to be used as a visual suit control. Such disk devices are, for example, toothed disks.

Next, a possible punching burr of the mold cavity 2 of the component 4 in an annular groove in the base body 11 of the rivet part 1 be arranged so that a substantially planar concern of the body 11 on the surface 25 of the component 4 is guaranteed. This groove also allows a trouble-free rotation of the rivet 1 in the mold cavity 2 ,

Finally, it should also be noted that the rivet parts 1 can be made in all sizes. The manufacturing processes may be either rotational, cold or thermoforming, or any other suitable manufacturing process. In particular, the main body 11 of the rivet part 1 only from a simple hex nut without first contact surface 17 and second bearing surface 18 exist, ie the hexagonal shape of the body 11 extends to the surface 25 of the component 4 ,

At It should be noted that all of the above Parts seen on their own and in any combination, in particular the details shown in the drawings as essential to the invention be claimed. Variations thereof are those skilled in the art common.
