Definitions
- the invention relates to a punching device for simultaneous connection a hollow profile on each of two opposite sides with each a flat component by means of a deforming fastening technology as punching, riveting or clinching, wherein the punching a Holding device in the form of an E-profile, the middle Leg during connection in the hollow profile protrudes and a first female carries in cooperation with one in the outer Legs of the E-profile arranged first stamp the connection of the Hollow profile with the first flat component causes, as well as a second Die in cooperation with one in the other outer thigh the E-profile arranged second punch the connection of the hollow profile effected with the second flat component.
- a deforming fastening technology as punching, riveting or clinching
- Such a punching device is known from DE 41 34 414 A1.
- Such punching devices with E-profiles as a holding device for The punching tools are used wherever in hollow sections simultaneously on two opposite sides deforming connections with other components are created should, for example, when riveting U-shaped profile Prefabricated parts in building construction, wherever to create walls a whole series of similar components juxtaposed and must be attached.
- a mounting device in the form of a single C-profile is provided, on one leg of a die and on the opposite leg cooperating with the die Stamp is provided.
- This is usually hydraulically driven and is for example, in the construction of a riveted joint with a rivet Mistake.
- a known device forming Compounds such as punched joints, riveted joints or Although clinch connections are easily made, and so are Hollow profiles with very different inner diameters and Moldings workable, however, only one can ever Liaison office at a given time.
- the matrices rigid and with a fixed axial length can be designed in the improved punching devices with E-profile usually with axial in their Length adjustable matrices worked, so that on the one hand from the inside of the hollow profile approached to be processed connection points can be, on the other hand, hollow sections of different Diameter can be processed without the Retaining device and the tools located thereon exchanged would have to be.
- Object of the present invention is in contrast, a Punching device of the type described above with the simplest possible technical means to improve, that on the one hand, how at the facilities with the E-profile bracket devices two Deforming connections simultaneously on opposite sides a hollow profile can be attached, but on the other hand a Adaptation to different shapes and diameters of hollow profiles can be effected with simpler means and thereby also a less expensive production of the holding device for the tools and thus the entire punching device is made possible.
- this object is also surprisingly simple how effective way solved by that the e-profile of the Mounting device of a first and a second C-profile is constructed, wherein the first C-profile at its the second C-profile adjacent leg the first die and the second C-profile at his the second C-profile adjacent leg carries the second die, and wherein at the free leg of the first C-profile of the first punch and on free leg of the second C-profile of the second punch is arranged, and that the first and the second C-profile in the punching direction against each other are movable.
- the two mutually movable C-profiles allow a very high flexibility and adaptability to different types of too machining hollow sections and are on the other hand because of their simple Build more cost-effective to manufacture than the known ones Holding devices in the form of E-profiles. Due to the The matrixes can be moved in the axial punching direction of the C-profiles on the two adjoining legs of the two C-profiles be made rigid as in the known simple Punching devices where only a single C-profile use finds, but in contrast to the punching device according to the invention generate only one single deforming connection at a time can.
- the C-profiles are independent movable from one another, so that also unbalanced or irregular Forms of hollow profiles can be edited arbitrarily.
- the C-profiles are common, preferably moved symmetrically to one another. Even with it can be large areas of different inside diameters of hollow sections cover, but only if they are built semi-symmetrical are. But this embodiment is much cheaper Can be produced as the above with an independent mobility the C-profiles. In particular, the drive technology can do a lot here be designed simpler.
- Hollow profiles For simultaneous processing of two opposite sides of a Hollow profiles is either the hollow profile with the two adjacent to connecting components, at least in the field of Connecting points are flat, in other areas, however more or less arbitrarily shaped, over the neighboring ones Thighs of the two C-profiles slipped, which on the minimal possible distance approached each other.
- the two adjacent legs of the C-profiles in the cavity of the machined Hollow profiles enter and then the stamp on the two free outer leg of the C-profiles against the now within the Hollow profile positioned to move dies and thus on both Pages to create the deforming connections.
- Punching device is provided that the first C-profile at his the second C-profile adjacent leg having a groove or channel, in which of the first C-profile adjacent leg of the second C-profile in the contracted state of the two C-profiles at least partially is recorded.
- This allows the two C-profiles to a certain extent be moved overlapping so that the middle leg of the thus formed "two-part E-profile" a particularly low Has expansion in the punching direction. That way too Hollow profiles are processed with very small inner diameters.
- Punching device provided a locking device by means of which the first C-profile at a preselectable fixed distance from the second C-profile can be held.
- a development of this embodiment is characterized in that the punching device with locked distance between the first and The second C-profile is movable in total. This is especially true of Advantage if the hollow sections to be machined do not have a rigid in itself mounted support device are slipped, but if the Holder device is to be moved into the cavities of the profiles. Due to the locking of the distance between the two C-profiles does not have to be readjusted each time the mutual distance.
- An embodiment of the invention is also particularly advantageous Punching device according to the invention, in which at least the first die, preferably also the second die rigid and without the possibility of a Length change is constructed. This can increase the life of the Matrices due to significantly less wear, as above be discussed, significantly extended.
- the figures of the drawing show an embodiment of the Punching device 1 according to the invention for simultaneously connecting a Hollow sections 2; 2 'on opposite sides 2a, 2b; 2a ', 2b' with a respectively applied thereto component 3a, 3b by means of a deforming fastening technology such as punching, riveting or clinching.
- a deforming fastening technology such as punching, riveting or clinching.
- components 3a, 3b may be flat outside of Connection area in a variety of forms are present.
- the punching device 1 comprises a Mounting device consisting of a first C-profile 6a and a second C-profile 6b is constructed.
- the first C-profile 6a carries on his the second C-profile 6b adjacent leg 7a a first die 4a and the second C-profile 6b adjacent to the first C-profile 6a Leg 7b a second die 4b.
- outer leg 8a of first C-profile 6a is a first punch 5a and the free outer Leg 8b of the second C-profile 6b a second punch 5b arranged in each case in cooperation with the corresponding die 4a, 4b simultaneously each a connection of the two opposite sides 2a, 2b; 2a ', 2b' with the respectively lying there flat components 3a, 3b effect.
- FIGS. 1a, 1b this is for a Hollow profile 2 shown with a relatively small inner diameter, so that the both C-profiles 6a, 6b have moved together to a minimum distance.
- FIGS. 2a and 2b show an example of a hollow profile 2 ', its opposite sides 2a ', 2b' a greater distance have from each other.
- Tools are achieved are by means of a generally hydraulically operating device, of which in the drawing only schematically the hydraulic cylinder 10a, 10b are shown, the two punches 5a, 5b against the corresponding Matrices 4a, 4b method to a corresponding deforming Connection between the sides 2a, 2b and 2a ', 2b' of the hollow section 2; 2 ' and to each adjacent flat components 3a, 3b to cause.
