- the tension member 11 is at least partially threaded therethrough Rod 154 by means of an adjusting head 155 adjustably connected to the hinge member 157.
- This adjustability causes the ratio of the distance d3 between the support elements 12.1, 12.2 to the maximum distance d2 of the tension element 11 at least 10: 1, preferably at least 20: 1.
- the tension member or the rod 154 are preferably guided, here by guide slots or a bore 71, so that a defined Force is guaranteed.
- the inventive arrangement causes that upon actuation of the lever arms 151.1,151.2 in the direction of the workpiece to be machined the traction element 11 moves away from this and a desired part of the maximum distance d2 travels. It is guaranteed that even with uneven Force on the lever arms 151.1, 151.2, the tension element uniform from the Dellstelle is moved away and no unwanted force components in the workpiece be initiated.
- the tension element 11 has here at its free working end 68 a coupling device 69 on.
- This coupling device 69 allows a detachable connection with a Connecting element 13 connectable to the deformable Dellstelle.
- this coupling device 69 by a recess in Area of the working end 68 of the connecting element 13 is formed, preferably a A latching mechanism, for example a groove or a groove, so that the connecting element 13 not only loose can be pushed into this recess, but in it finds a defined stop.
- alternative coupling devices e.g. a firmly latching bayonet connection can be used.
- the construction of the arm 16 with the carriages can be clearly seen in the plan view of Figure 2 , which shows a preferred embodiment of the arm 16 with two spaced, straight rail parts 165.1, 165.2.
- the support devices 162.1, 162.2 can additionally be determined at different positions of the carrier element 16, so that their mutual spacing can be varied.
- a particular advantage of the invention lies in the fact that the bulging device can be adjusted very flexibly and adapted to practically all imaginable workpiece geometries, but that the distance d3 between the bearing elements 12.1, 12.2 remains constant during use of the tool and thus a safe and accurate Support is achieved while avoiding the disadvantages of the prior art.
- the distance d3 may indeed be adjustable, but not undesirable changes in the use of the tool or joint assemblies are required, which make the tool unstable (cf the Achsgelenke 32 in US 4,026,139).
- the distance between the tension element and the support elements 12.1, 12.2 remains constant.
- unwanted force components are transversely effected to the material surface, which would affect the use of a bonding member 13 to be bonded due to the shear forces occurring in the adhesion very disadvantageous.
- the device according to the invention allows that the restoring forces can be introduced substantially perpendicular to the bulge region (B) and a substantially homogeneous force flow is achieved.
- the support arm may be of the straight rail shape differ.
- the carrier arm in the middle area e.g. have a yoke-like, upwardly facing geometry.
- the Support devices 162.1, 162.2 remain in this case in the manner described above slidable straight rail parts.
- Such yoke-like transitions can with the Rail parts mechanically connected or formed integrally with these.
- FIG . 3 a shows a support element 12 in a lateral view.

- a force (F) by pressing the lever arms (151.1, 152.2) are introduced substantially perpendicular to the bulge region (B).
- the end surface 61 need not be flat and can be adapted to the shape of a bump be, e.g. by the contact area or virtually all of the element 13 from a material that by cutting or thermal deformation of the be adapted to the respective bulge shape, z. B.dnch that the contact area a thermoplastic material and in the plastic state before bonding for shape adaptation is pressed into the bump.
- the actual bulging process is now as follows. Connecting a connector 13 with the material layer WS is made as described above. Thereafter, the support means 162.1, 162.2 of the lever arms 151.1, 152.2 with respect to a support element and other adjustment parameters, such as adjustable Feet 52 of the support elements, adjusted and aligned. Thereafter, the tension element 11th connected to the connecting element 13 via the coupling 63, 69 and the support elements 12.1,12.2 on the workpiece to be machined at the desired location stated.
- By actuating the lever arms 151.1, 152.2 is a substantially perpendicularzum Bump area B standing force F exerted on the latter. After the desired Plastic deformation of the bump is usually the first tool by loosening the Coupled off the connecting element 13 and finally the connection between Connection element 13 and material layer WS solved.
