The NHE recognizes the rivet projection (U), serves as a hold-down device and helps to reliably recognize components before forming with tolerance errors or missing components. As result of the HPP-25 monitoring capability, inspection of components pre or post forming can be eliminated. Additional inspection Stations can be eliminated and production cost can be reduced.
Additional NHE functions, which can be implemented quickly and safely with the Process Control HPP-25:
Primary riveting mode H with HPP-25
Integrated, separate measuring system
Produce precise formed rivet head height ,H' at different component heights, despite flexing of the machine
NHE-U with HPP-25 and auto-compensation allows a formed head height, relative to the rivet protrusion. Smaller protrusion = less forming, greater protrusion = more forming. Amount of compensation can be determined
Rapid approach / working speed based on the work piece elevation for improved productivity
Touch probe acting as a hold-down device on the workpiece base:
NHE-Std: up to 10-40N hold-down force. Adaptable to RNE 151-431
NHE-Big: up to 20-300N holding force. Adaptable only to RNE 281-481
Note: A retrofit may need replacing the length of the forming tool, the form tool holder, and the pressure cup
Subject to change.
