20130098534 | METHOD FOR CONNECTING A PLASTIC WORKPIECE TO A FURTHER WORKPIECE - Presented and is described is a method for connecting a plastic workpiece to a further workpiece with the following steps: providing a plastic workpiece, comprising a first abutting surface, provided on which is a pin having an end face facing away from the first abutting surface; providing a further workpiece, comprising a second abutting surface and a working surface, a through-opening which is adapted to the cross section of the pin and extends from the second abutting surface to the working surface being provided in the further workpiece; placing the further workpiece and the plastic workpiece against each other in such a way that the second abutting surface lies on the first abutting surface, the pin extending through the through-opening, beyond the working surface; placing a friction tool against the further workpiece, the friction tool having a friction pin driven in a rotating manner and comprising a friction surface extending perpendicularly in relation to the axis of rotation and having a clamping ring comprising a clamping surface, placement involving the friction surface being placed flat on the end face and the clamping surface being placed flat on the working surface; rotating the friction pin, so that the frictional heat produced by friction between the friction surface and the end face brings the pin into a plastic state, and moving the rotating friction pin parallel to the axis of rotation toward the working surface, so that the pin is plastically deformed. | 04-25-2013 |
