摘要
The rivet pins on the plastic component are inserted through corresp. holes on the plate-shaped object with the pin ends projecting slightly on the other side. The pin ends are heated by hot air blown from a tube onto them until they reach m.pt. The heating process is slower than is the case when a hot riveting tool is used. After heating, a cold riveting tool is applied to the heated rivet pins, causing them to deform plastically, their projecting parts being pressed against the plate-shaped object to form rivet heads. The pins are then allowed to cool in the cold riveting tool which maintains pressure force on them. The process of allowing the rivet pins to cool in the cold riveting tool under maintained pressure produces a constant tension force in them, thus ensuring a completely gap-free union.
