Riveting is usually what we call lock riveting and riveting. It is mainly used for riveting work on auto parts. In general, the types of riveted structures can be divided into three categories according to the riveting temperature, application range, and riveting force.
First, according to the riveting temperature classification
1, according to the riveting rivets when the heating temperature is divided into cold riveting, hot riveting and mixing riveting. Cold riveting refers to the riveting of rivets at room temperature. The impact of cold riveting equipment is relatively large. The rivets are required to have good plasticity and small deformation resistance.
2. Hot riveting refers to the riveting performed after the rivet is heated to a certain temperature. When the rivet is heated, the strength is reduced and the plasticity is increased, so that the deformation resistance is greatly reduced and the riveting is easily formed.
3, external force required for riveting is significantly reduced compared to cold riveting, so rivets with larger diameters and riveting in large quantities usually use hot riveting.
4. Hybrid riveting is to locally heat the rivet head and is mainly used for riveting of larger diameter rivets.
5, local heating rivet head, rivets can be riveted in the process. Does not change the shape of the rivet bar and keeps the process stable
