The equipment has a compact structure, stable performance, convenient and safe operation. The riveting machine mainly relies on rotation and pressure to complete the assembly. It is mainly used in occasions where rivets (hollow rivets, hollow rivets, solid rivets, etc.) are required. Common models include pneumatic, hydraulic and electric, single-head and double-head specifications. The common types are mainly automatic riveting machines and rotary riveting machines.
