Automatic
Riveting Machine

A loose rivet (under-set) is insufficient stroke or insufficient pressure — not luck. We fix the stroke first and use pressure only for fine adjustment, and the pair is locked in a recipe. Change the rivet specification and we re-trial; we never carry the previous setting over. In production we check every 30 pieces for head cracking, single-sided set and die marking, and pull-test on a sample.

It can, which is why the lower die is contoured to the part. The support face is machined to the part profile, radiused and polished, and anything touching a visible face gets polyurethane or a nylon die. Thin panels are set with low pressure in several steps rather than one full stroke. Show me the part and the die gets made to it.

Yes, but pull riveting and press riveting are not the same machine. A pull rivet forms by breaking its mandrel, so the tooling is a nose assembly or a pull module. Press riveting forms by squeezing between punch and die. Force and stroke differ completely, and one machine does one of them. If you use blind rivets, I quote a pull-riveting solution — I won't try to convert a press.

It depends on station count, number of rivets and whether the part is flipped. One station sets one rivet per stroke; with three, four or five stations they run in sequence, so cycle time is station count divided by set time. Tell me rivets per part and the cycle you need and I'll work out the stations — a bare "pieces per minute" figure is meaningless because it changes with the next product.

Driven by station count, rivet specification and whether feeding is automatic. The difference between three and five stations, and between manual and bowl feeding, sits in the stations and the feed mechanism. Send rivet spec, rivets per part and target cycle, and I'll quote a range against a proposal.

The set head is a wear part, and once it wears the set is out of spec — so the head is checked for flatness at the start of every shift and replaced when it chips. Replacing a set head is neither expensive nor complicated, but the tooling is made to your rivet head shape, so keep a spare set on the shelf.

Yes. Send parts and rivets, a batch of each. You get back photographs of the set, pull-test data, and a note on die marking — which matters especially for visible parts.

Simpler than polishing. The operator loads, unloads and watches the set head. The difficult part is first-off setting, and we do that and store it as a recipe, so your people just recall it for the next part.
