- FIG. 1 shows a method for connecting a first component to a second component by plastic deformation according to the prior art.
- FIG. 2 shows a method for joining a first component to a second component by plastic deformation according to a first exemplary embodiment of the present invention.
- FIG. 1 shows a method for connecting a first component 1 to a second component 2 by plastic deformation according to the prior art, with snapshots being illustrated from left to right in the course of the illustrated method.
- the first component 1 is provided as a hollow body, preferably as a tube, with an axis of symmetry 4.
- the first component 1 has a deformation region 10, wherein the deformation region 10 is so bulged by the plastic deformation that a (resulting from the plastic deformation) bulge non-positively and / or positively cooperates with the second component 2 and By this interaction, the first component 1 is held together or connected to the second component 2.
- the first component 1 is heated in the deformation region 10 before the plastic deformation in a first method step.
- the material properties of the first component 1 modified so that the plastic deformation in the heated areas compared to the non-heated areas can preferably be done.
- heating advantageously reduces the likelihood of cracking during deformation.
- an inner punch 5 is arranged inside the cavity, in particular within the deformation area.
- the inner punch 5 is inserted along an insertion direction 6.
- the second component 2 is arranged in the deformation region 10 on the first component 1.

In particular, a pressure from the movable section 15 acts on the first

- the Retracted inner punch 5 that the inner distance - for all positions along the axis of symmetry 4 does not fall below a minimum distance.
- the minimum distance is 0.1 mm.
