How often does the rivet fall out of the jaws?
If rivets frequently fall out, it may indicate an alignment issue at the track-to-jaw transition or worn jaw springs. Both can be checked and adjusted to improve rivet retention.
Why do rivets get stuck in the tracks?
Rivets can get stuck if there’s a buildup of foreign debris or dirt in the track. Regular cleaning can prevent this issue, ensuring smooth rivet flow.
Why isn’t the rivet reaching the jaws from the selector?
This could be due to debris buildup or rivet misalignment within the selector. Checking the selector blades for wear and confirming proper spacing between blades can help resolve the issue.
What causes “eyelashes” on rivets after forming?
Eyelashes are often linked to rivet concentricity or jaw/driver misalignment with the rollset/anvil. Proper alignment ensures clean, consistent rivet forms.
Why is the rivet “telescoping” or collapsing instead of rolling or forming?
This issue could stem from misalignment between upper and lower tooling, worn tooling, or changes in rivet geometry. Reviewing tooling setup and condition can help address telescoping issues.
Why does the rivet fall out of the jaws before engaging with the rollset/anvil?
Bent or worn jaw springs are a common cause. Replacing or adjusting these springs can help ensure secure rivet handling during the forming process.
Why aren’t rivets feeding out of the hopper?
Possible causes include worn details within the hopper bell, an overfilled hopper bowl (above 50%), or issues with the ratchet assembly not rotating per impact cycle. Regular maintenance can
prevent feeding problems.
Why does the riveter occasionally fail to cycle when activated?
This may be due to a safety probe not advancing fully, which could be resolved by adjusting the down stop or upgrading to a JLSD for complex part geometries. Misaligned sensors or clutch interface issues specific to Adtech and Milford riveters can also contribute to cycling issues.
