Abstract
A riveting apparatus includes a hot air pipe; a connection pipe coupled to the hot air pipe; a forming tool having a configuration in which peripheral and center portions project downward and portions existing therebetween are curved upward, defined with discharge holes which extend in axial and radial directions, and coupled to a lower end of the connection pipe so that hot air having passed through the connection pipe can be discharged through the discharge holes to heat an end of a rivet to thereby allow the forming tool to form the end of the rivet into the shape of a head; a moving unit coupled to the hot air pipe or the connection pipe to move the forming tool upward and downward; and a guide surrounding the forming tool so that hot air discharged through the discharge holes can be directed toward the end of the rivet.
Claims6
A riveting apparatus suitable for fastening a plurality of plate members by forming an end of a rivet, made of synthetic resin, into a shape of a head through heating and pressing, the apparatus comprising:
- a hot air pipe for supplying hot air;
- a connection pipe having a shape of a hollow tube and coupled to a lower end of the hot air pipe;
- a forming tool having a configuration in which a peripheral portion and a center portion project downward and portions extending therebetween have a concavely curved lower surface, having discharge holes which extend in axial and radial directions, and coupled to a lower end of the connection pipe so that hot air having passed through the connection pipe can be discharged through the discharge holes to heat the end of the rivet, thereby allowing the forming tool to form the end of the rivet into the shape of the head;
- a moving unit configured to move the forming tool upward and downward;
- and
- a guide configured to surround the forming tool so that hot air discharged through the discharge holes, which are defined in the forming tool and extend in the radial directions, can be directed toward the end of the rivet.
