| 摘要 |
The invention relates to a jointing device for producing a joint assembly, a push-through jointing method and a push-through joint assembly between a first workpiece (2) and a second workpiece (3). The device has a die (4) that can be introduced into the recess of a swage (5). The first workpiece (2) is pressed from above and is given a pot-shape that presses into the second workpiece (3) and shapes it in a downwards direction without any cutting. The shape of the first workpiece forms an undercut with the second workpiece (3). The peripheral wall of the recess of the device has wall sections (10) that are disposed on levers (11). The levers can be moved into a working position by exerting pressure from above and can be fixed in said position, forming undercut areas. The levers (11) can be moved into a release position by moving the joined workpieces (2,3) in an upward direction, whereby the undercut areas are released entirely. |
