Device for connecting objects using at least one connection element which can be plastified using heat

摘要

The device has a heatable calotte (12) forming a rivet head at a connection element and provided with a shaft (10). The calotte is movable away from the connection element and is movable towards the connection element. A cooling unit cools the calotte using a cooling fluid i.e. air. The shaft includes a central cooling fluid supply channel (16) extending to a calotte body (14). Cooling fluid channels (18) are provided within the calotte body and are radially outwardly guided based on the fluid supply channel.
