Explanation of Orbital Riveting Working Principle

This unique compound motion causes the contact point between the die (Mould in Diagram 1) and the rivet (River) to continuously vary, transforming the powerful axial force into a uniform, continuous radial material flow. Guided by the riveting needle (Rotary rivet needle) and constrained by the die cavity, the rivet material spreads evenly outward—akin to being “gently kneaded” rather than “forcibly upset.” This results in a reliable joint that is free of cracks, highly precise, and has a smooth finish, all achieved with minimal riveting force (only 10%-20% of traditional press riveting).

Orbital riveting is an advanced cold-forming process. Its core lies in maintaining a precise tilt angle (α, typically 3°-8°) between the riveting spindle axis and the forming die axis. During operation, the riveting spindle does not press down vertically. Instead, it drives the die to perform a continuous 360° eccentric orbital movement (shown as the S trajectory in Diagram 2) while simultaneously feeding along the Z-axis.

Riveting Shape Selection and Application

Our servo orbital riveting enables diverse shapes — including Flat, Countersunk, Ball Head, Flared, and Custom forms — to meet varied functional and space requirements. We provide standard shape options (S1–S9) and support tailored designs for precise, reliable, and space-efficient joints.

Equipment detailed design

The machine body is made of high-performance HT cast material, using a one-piece casting process, unlike other brands that use welding, splicing, or screw fastening. We adopted this approach to improve the rigidity and deformation resistance of the machine body. One-piece casting effectively enhances equipment stability and precision, and significantly increases durability, extending the service life to several decades.
	Through data verification and analysis using CAE structural analysis, the design redundancy requirements are fully met, improving equipment durability and safety.
The exterior design is based on ergonomic principles, tailored for operators of different ages and body types, prioritizing safety, efficiency, and aesthetic appeal, while also ensuring ease of operation.
	Utilizing integrated high-performance industrial PLCs and HMIs, controlled by a core algorithm system with independent intellectual property rights, the control accuracy and application modes are significantly improved.
By adopting an integrated coaxial power head solution, which integrates displacement, rotation, pressure sensors, and moving parts into a single power head unit, problems such as displacement deviation, insufficient dynamic balance, and excessive vibration can be effectively reduced, thereby improving the reliability of equipment operation.
	The rich expansion interfaces provide external control and data interaction capabilities, and also offer interfaces for connecting with ERP and MES systems.  This fully supports data recording and storage, facilitating the complete digital transformation of the factory.
The design emphasizes attention to detail, including active cooling vents and exhaust ports.  Safety is also a priority, with the power connector using universal international standards to be compatible with power requirements in different regions and countries.  Additionally, an external discharge expansion port is included to accommodate a wider range of usage scenarios.
