Description
Punch rivet pliers with punch rivet holding device
Description
The present invention relates to punch rivet pliers.
Prior art
In the metalworking industry, especially the automotive industry, connections by means of punch rivets are widespread. In punch riveting, a punch rivet is driven by the punch of a setting tool into the plate-shaped workpieces lying flat on one another in such a way that the punch rivet punches through the upper workpiece and penetrates the lower workpiece without punching through it. In this process the plate-shaped workpieces lying on one another are supported by a die of the setting tool with a cavity (recess). The punch rivet expands during the riveting process and in doing so deforms the material of the workpieces so that this is displaced into the cavity of the die and forms a so-called closing head, due to which the rivet and the workpieces are joined to one another positively.
In punch riveting, the rivet should be aligned prior to riveting in the setting tool, in particular centred, and not come loose unintentionally. The rivet can be guided, for example, by flexible fibres or "fingers" and centred and held by these. Spring-loaded (cf. WO 2012/046002 A2) or elastomer or polymer centring and holding elements can also be used. The rivet can also be pressed by a rivet pusher against a counterbearing and held thus.
In the post-published DE 10 2014 203 757.3 of the applicant, it is described that the process forces required for the riveting process, which are normally very high, can be significantly reduced by means of vibrations (in particular ultrasonic) when punch riveting. This results in system advantages (e.g. lighter system, better accessibility), process advantages (e.g. improved cutting process, reduction in delaminations when punch riveting composite fibre materials, expansion of the rivetable material spectrum) and cost advantages (e.g. lower consumption costs for OEM). However, the vibration device necessary for the vibrations requires additional construction space between the shank ends, which leads to an undesirable enlargement of the punch rivet pliers.
Contact between rivet and holder in the case of vibration supported punch rivets can lead to weldings between rivet and holder due to the superimposed (ultrasonic) vibration.
It is desirable, therefore, to have an alignment and holding option available for punch rivet pliers with vibration support in which the punch rivet does not touch any non-vibrating components and preferably only comes into contact with the punch.
Disclosure of the invention
According to the invention, punch rivet pliers with the features of claim 1 are proposed. Advantageous configurations are the object of the subordinate claims as well as of the following description.
Advantages of the invention In the scope of the invention, punch rivet pliers are presented that for the alignment, in particular centring, 5 of a punch rivet, allow fluid under pressure to flow out around this. Alignment then takes place by means of the Bernoulli Effect. The aligned punch rivet is held on the punch by positive force. A reliable and precise alignment and holding option is thus provided in a simple manner for 10 punch rivet pliers with ultrasonic support, wherein the punch rivet does not touch any non-vibrating components and preferably only comes into contact with the punch. This prevents unwanted weldings and reduces wear.
The invention is preferably suitable for punch rivet pliers with a vibration device to prevent unwanted weldings there. Punch rivet pliers of this kind have particular advantages in lightweight automotive body construction, since vibration or ultrasonic punch riveting with the suitably designed system technology makes many joining tasks in the field of mixed material construction easier and makes new material thickness combinations possible. However, punch rivet pliers with vibration support can also be used advantageously in other areas and/or for joining other materials. The process forces required for the riveting process, which are normally very high, are reduced considerably by means of vibrations. This results in system advantages (e.g. lighter system, better accessibility), process advantages (e.g. improved cutting process, reduction in delaminations when punch riveting composite fibre materials, expansion of the rivetable material spectrum) and cost advantages (e.g. lower consumption costs for OEM).
Compressed air, which can be supplied easily and cost-effectively, is expediently used as fluid for the outflow. Depending on the purpose, however, gases or gas mixtures such as e.g. inert gases (so-called shielding gases) or reactive gases can be used. A conventional source of positive pressure such as a compressor or a pump can be 10 used.
To hold the punch rivet on the punch by positive force, vacuum force, magnetic force or molecular force is preferably used. Vacuum force serves to suck the punch rivet onto the punch. A conventional vacuum source such as e.g. a pump can be used for sucking the punch rivet onto the punch. The positive pressure source can be the vacuum source at the same time, which simplifies the number of necessary components and the complexity of the construction. If the punch rivet is made from ferromagnetic material (in particular iron and/or nickel), it can be attracted to the punch by magnetic force. For magnetic attraction of the punch rivet to the punch, a permanent magnet or preferably an electromagnet can be 25 used. If the surface of the punch rivet is smooth and even, it can adhere by molecular force e.g. to an adhesion film.
The setting tool preferably has a punch and a die, which 30 are pressed against one another by a pliers drive and between which the punch rivet is placed. A preferred setting tool also has a retaining device, which presses together the join partners to be connected and presses them against the die.
The setting tool is preferably formed so that the fluid under pressure flows out around the punch rivet in the form of a cylinder jacket or surface of a cone. To this end the setting tool can have an annular gap in particular as an outflow opening, which is formed for example in the punch or between punch and a housing surrounding the punch. A housing of this kind surrounding the punch can in particular be the retaining device. To aspirate the punch rivet, the punch of the setting tool has at least one recess, preferably a central hole, which is connected to the vacuum source.
The vibration device is preferably formed as an ultrasonic system and has in particular an ultrasonic transducer, an amplitude transformation unit and/or a sonotrode. The ultrasonic system in this preferred embodiment can correspond to that of an ultrasonic welding system. High-frequency alternating current is produced with the aid of a generator and transmitted via a cable to the ultrasonic transducer, the so-called converter, which generates from it mechanical ultrasonic frequency with the aid of the piezoelectric or magnetostrictive effect. These vibrations are transmitted via an amplitude transformation unit, the so-called booster, to the sonotrode. Sonotrodes are tools in which resonance vibrations are set off by the introduction of high-frequency mechanical vibrations (ultrasound). They create the connection from the ultrasonic generator to the workpiece and punch rivet and adapt the ultrasonic vibration to the processing task (impedance adjustment). Different applications call for different types of sonotrodes, which are manufactured mostly from steel, aluminium or titanium. The amplitude of the vibration and the impedance adjustment are influenced by the shape and mass of the amplitude transformation unit. A vibration device can thus be provided that is based on proven components and methods.
The punch of the setting tool is preferably the sonotrode 10 of the ultrasonic system. This thereby saves on components.
It has proved especially preferable if the vibrations have a vibration width (this is understood to be the sum of the height of the amplitude in a positive and negative vibration direction) of between 10pm and 100um, in particular at a frequency of the vibrations of between 15kHz and 40kHz. This is thus a frequency range that typically corresponds to ultrasonic vibrations.
Another advantageous configuration of the method according to the invention provides that the travel and/or the frequency of the vibrations is/are changed during the joining process. For example, a relatively large travel can be provided at the start of the joining process, which is reduced as the indentation or impression depth of the rivet increases.
With regard to the direction of coupling of such (ultrasonic) vibrations into the rivet and the components, different variations are conceivable: in a first configuration of the method, it is provided that the vibrations are coupled, at least substantially, into the rivet and/or the at least two components in parallel to the joining direction of the rivet. In this case, particularly small indentation or impression forces are required for the rivet.
Depending on the components and rivet geometry used, however, it can also be advantageous if the vibrations are coupled, at least substantially, into the rivet and/or the at least two components perpendicular to the joining direction of the rivet.
In an alternative configuration, it can be provided that the vibrations are coupled into the rivet and/or the at 15 least two components at an oblique angle to the joining direction of the rivet.
In yet another alternative configuration it can be provided that the vibrations are coupled, at least substantially, into the rivet and/or the at least two components in a circumferential direction of the rivet.
Other advantages and configurations of the invention result from the description and the enclosed drawing.
It is understood that the features cited above and to be explained below can be used not only in the respectively indicated combination, but also in other combinations or alone without departing from the scope of the present invention.
The invention is represented schematically in the drawing with reference to an example embodiment and is described below in detail with reference to the drawing.

Detailed description of the drawing
The invention is described with reference to figures 1 to 4, wherein identical elements are designated by the same reference numbers.
Figure 1 shows a section of a preferred embodiment of 30 punch rivet pliers according to the invention in a schematic longitudinal sectional view and designated 100 overall.
The punch rivet pliers 100 have a setting tool 150 for setting punch rivets 10 in join partners 20, 21. The two join partners 20, 21 can in particular be two plates. The setting tool 150 has a punch 151 and a die 152 and, in the preferred embodiment shown, also a retaining device 153. As is known, the punch 151 is used to press the punch rivet 10 into the join partners 20, 21, wherein the join partners are pressed against the die 152, which has a suitable profile for the respective joining. The retaining device can be moved independently of the punch vertically in the figure in direction C and is used to press the join partners 20, 21 against the die 152.
According to the embodiment shown, the punch rivet pliers 100 also have a vibration device, formed here as an ultrasonic system 160, to set the setting tool 150 vibrating. According to the embodiment shown, the vibrations are directed longitudinally in longitudinal direction D. The ultrasonic system 160 is constructed here corresponding to an ultrasonic system of an ultrasonic welding device and has an ultrasonic transducer or ultrasonic converter 161, an amplitude transformation unit or booster 162 and a sonotrode 163, which here represents the punch 151 at the same time.
High-frequency alternating current is produced by a generator and transmitted via a cable to the ultrasonic transducer, which generates mechanical ultrasonic frequency from this with the aid of the piezoelectric or magnetostrictive effect. These vibrations are transmitted via the amplitude transformation unit to the sonotrode.
The punch rivet pliers 100 have a pliers drive (not shown) for opening and closing the punch rivet pliers 100. The pliers drive 140 can be formed by an electric motor, hydrostatically or pneumatically. To press the rivet 10 in, the punch 151 is moved towards the die 152 in the figure along direction B. The alignment and holding of a punch rivet 10 are now explained in greater detail with reference to figures 2 to 4.
First a punch rivet 10 is arranged in front of the punch 151, expediently by an automatic supply device. In the embodiment shown, the punch 151 is surrounded by the retaining device 153, wherein an annular gap 170 is formed between the punch 151 and the retaining device 153. The annular gap 170 is connected to a positive pressure source 171, which emits compressed air 172 in the embodiment shown, which air flows out of the annular gap 170 as an outflow opening. The compressed air 172 flows round the punch rivet 10 in the embodiment shown in the form of a hollow cone. The compressed air 172 flowing around the punch rivet 10 in the form of a hollow cone leads by means of the Bernoulli Effect to an alignment, here centring, of the punch rivet 10 relative to the annular gap 170.
Furthermore, the punch 151 in the embodiment shown has a central hole 180, which is connected to a vacuum source 181. The vacuum source 181 aspirates air 182 through the hole 180, due to which the punch rivet 10 is sucked against the punch 151, as shown in figure 3. The vacuum source 181 can be the positive pressure source 171 at the same time, wherein a suction opening of a pump (not shown), for example, is connected to the hole 180 and an outlet opening of the pump is connected to the annular gap 170 in a fluid-conducting manner. Instead of the suction shown, a ferromagnetic punch rivet can also be held magnetically on the punch 151, for example.
As soon as the punch rivet 10 is aligned and held on the 10 punch 151, the outflow of compressed air 172 can be terminated, preferably by closing a valve (not shown) between positive pressure source 171 and annular gap 170.
The setting tool 150 is then brought into contact with the join partners 20, 21, wherein the retaining device 153 presses the join partners 20, 21 against the die 153, as shown in figure 4. The punch rivet 10 continues to be held by means of a vacuum on the punch 151. The ensuing punch riveting process takes place in a conventional manner, i.e. the punch rivet 10 is pressed by the punch 151 acted upon by force into the join partners 20, 21 so that these are connected. If the punch rivet pliers are a preferred embodiment of the invention with vibration support, the punch rivet 10 is acted upon by ultrasonic vibrations, in particular during the pressing.
