Heavy-duty flex coupling
WHAT
Large rivets require a high forming force - yet the rivets should not be compressed or bent in its length.
WHY
Due to the rivet size and strength, it takes a longer cycle time to form large, tough rivets. That, in turn, leads to high temperatures at the rivet and plunger and consequently to a high wear of the tool.
HOW
Radial riveting provides ideal ‘holding’ of the rivet shaft during the forming processes, which results in efficient forming. The friction is minimal, the forming time is short, and thus, the tool wear is minimized. Nevertheless, it is recommended to use lubricant on the rivet / forming tool.
