Riveting Count and Anti-Miss Mechanism

  • The E518 features a precise riveting count system designed to prevent missed rivets. Users can set the required number of riveting operations per part, and the machine counts each completed operation. Once the target is reached, the counter resets automatically, with an audible alarm indicating completion. The system ensures that incomplete or missed rivets are not counted, maintaining process integrity. Additionally, the riveting counter tracks the total number of operations, enabling efficient monitoring of production progress and equipment utilization.

Traceable Process for Enhanced Quality Control

  • The E518 riveting machine ensures comprehensive traceability with real-time pressure and position curve data saved directly on the software interface. This feature allows the entire riveting process to be reconstructed for easy analysis. Multiple real-time detection methods effectively identify material tolerance deviations, positional shifts, and processing issues. Coupled with live riveting data, the system automatically generates optimized quality control pathways, significantly improving reliability and ensuring consistent product quality.
