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.
