摘要:
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.

The invention provides a pipe expanding apparatus of a thin wall stainless steel pipe in which a strain is not generated in a flange and a yoke, even when a pipe expanding rubber swells. The invention includes a flange which forms one inclined surface of a chevron shaped projection portion by internally fitting a thin wall stainless steel pipe, a yoke which forms the other inclined surface of the chevron shaped projection portion by being coupled at its one end side to the flange, and is coupled to a cylinder at its other end side, a guide rod which is coupled to a piston of the cylinder, and a pipe expanding rubber which is pinched between a step portion of the guide rod and a backup ring and expands the thin wall stainless steel pipe.

A device and method for joining fitting parts provided with a passage opening on hollow profiles through partial expansion of the hollow profiles at the location of the fitting parts is provided. The fitting parts are slid on with the passage openings and are held in position by means of fluid high internal pressure expansion of the hollow profile. The device includes an expanding lance, which can be slid into the hollow profile and exhibits an axial borehole for the purpose of guiding the pressure fluid. The axial borehole is connected to a fluid high pressure generating system and exhibits a cross channel with an outlet for the pressure fluid in the direction of the hollow profile location to be expanded. The shell surface of the expanding lance exhibits sealing elements that are spaced apart and that define the outlet so as to seal axially on both sides against high pressure. To a reliable joining of the fitting parts on hollow profiles even when the hollow profiles exhibit small outer diameters, it is proposed that the expanding lance comprises two separate, aligned oblong components, of which at least one bears the axial borehole which empties freely on an end face near the outlet. The facing ends of the lance components form the cross channel for the axial borehole of the expanding lance. Furthermore, the device includes a drive unit operable to drive the two lance components into respective hollow profile ends, and are supported on an end side during the expansion phase.
