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

Featuring an adjustable stroke design, it flexibly adapts to different part sizes and process requirements. The machine body is made of high-quality carbon structural steel, precisely machined and treated to ensure long-term stable operation and positioning accuracy. The worktable adopts a multi-slot modular design, compatible with various fixtures, enhancing production flexibility. The integrated control box combines the operation panel, speed control unit, and protection functions, achieving simple and efficient human-machine interaction.
	This safety light curtain system is a high-performance, non-contact safety protection device designed to ensure the safety of personnel working with industrial automation equipment and in hazardous machinery areas. By creating an invisible “light barrier,” it continuously monitors for intrusions into a specific area and immediately triggers a shutdown before any danger occurs, fundamentally preventing personal injury and equipment damage.
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.
