[0002] Pressure riveting is divided into hot pressure riveting and cold pressure riveting. Hot pressure riveting is a process for connecting thermoplastic materials with other metal or non-metal parts. When in use, the rivet post is first heated to soften it, and then pressure is applied to the softened rivet post through the rivet head of the jig to form it. When the rivet post cools and hardens again, two or more parts are firmly connected together. The heating and pressure riveting of the rivet post are completed by different equipment.
[0003] In hot riveting, the rivet post is heated and then inserted into the connecting hole. Affected by the ambient temperature, or if the rivet post has been away from the hot furnace for a certain period of time during riveting, the temperature of the rivet post may drop. Sometimes, the heater needs to be taken out again to reheat the rivet post during riveting. Therefore, this solution provides a riveting machine riveting structure, which adds an auxiliary heating device on the basis of the existing riveting structure to realize the integration of rivet post heating and riveting.
