Abstract
A method is provided for connecting a first component to a second component. The first component has a deformation region, wherein the deformation region is at least partially heated in a first step. An inner die for the plastic deformation is provided in a second method step. The first component is plastically deformed in the deformation region in order to connect the first component to the second component in a third step, and wherein the deformation region is at least partially contacted by the inner die in the second step.
Claims18
A method for connecting a first component to a second component, the method comprising the steps of:
- providing the first component with a deformation region;
- at least partially heating the deformation region;
- providing an inner die for the plastic deformation;
- and
- plastically deforming the first component in the deformation region to connect the first component to the second component and wherein the deformation region is at least partially contacted by the inner die, wherein plastically deforming the first component comprises an upset bulging, wherein the inner die has a movable portion, the movable portion being contacted at least partially with the deformation region, wherein in the step of plastically deforming the first component, the movable portion is moved out or spread, the inner die being arranged in a hollow body of the first component, the inner die being rotated during said step of plastically deforming the first component.
An inner die with movable portions for connecting a first component to a second component by plastically deforming the first component in a heated deformation region of the first component to connect the first component to the second component and wherein the inner die includes at least one movable portion to at least partially contact the deformation region, wherein plastically deforming the first component comprises an upset bulging, the movable portion being moved out or spread during plastically deforming the first component and the inner die being rotated during plastically deforming the first component.
A method for connecting a first component to a second component, the method comprising the steps of:
- providing the first component with a deformation region;
- at least partially heating the deformation region;
- providing an inner die for the plastic deformation;
- and
- plastically deforming the first component in the deformation region to connect the first component to the second component, wherein the deformation region is at least partially contacted by the inner die, the inner die having a movable portion, the inner die being arranged in an interior space of the first component during the step of plastically deforming the first component, the movable portion contacting at least a portion of the deformation region during the step of plastically deforming the first component, wherein the inner die is rotated during the step of plastically deforming the first component.
