National Rivet & Manufacturing Co.

Positioning fixtures are stationary fixtures designed to hold one or more components in place for positive alignment during riveting (positive alignment is critical for consistent results!). Movable fixtures can improve production efficiency and operator safety. We can engineer fixtures to move manually or automatically, as well as incorporate multiple positive stops or interlocks. Moveable fixtures allow a single machine to set multiple rivets in a part or component, or they can orient and support the part in such a way that one person can do the work of two.

Maximum productivity depends on fast, accurate delivery of rivets and parts to the riveter. For example, National Rivet often recommends the use vibratory feeders to deliver rivets, unusually shaped cold headed parts, washers, electrical contacts, coil springs, spacers and other parts accurately and with great repeatability. Similarly, we can design systems to transfer parts to the machine via slide, tube or automatic placement device.

Compensators enable riveting machines to accommodate varying work thicknesses. Anvil arm compensators allow the anvil to move vertically as the rivet is driven down through the work, supporting the anvil with spring or air pressure. Top pin compensators work in a similar fashion, except that they use a spring-loaded top pivot pin. With either model, pressure can be adjusted so that each rivet is set with the same amount of pressure regardless of part thickness.

Shuttle Fixture. A shuttle fixture allows a machine operator to load the component parts safely over the anvil outside of the riveting area. The parts can then be shuttled into position to complete the riveting operation. The point of operation can be guarded by either dual anti-tiedown safety switches or a single switch plus an electrical interlock placed at the shuttle fixture in stop position.

Reconditioned and Used Riveting Machines Used Riveting Machines Reconditioned Riveter Setting Machines Just like some people favor buying used cars, there are people who prefer to purchase reconditioned riveters. But don’t confuse a reconditioned National Rivet rivet setting machine with any old used, retooled or rebuilt riveter. As part of National Rivet’s rigorous process, we: Completely tear down the machine Thoroughly inspect every component Replace all worn parts, which may include bushings, pins, clutches, linkages, anvils, jaws, drivers, hoppers, arms and accessories Paint the unit for a near-new appearance Thoroughly test the unit in-house before we release it At National Rivet, our fully reconditioned riveters provide like-new performance and come with a like-new warranty. People count on reconditioned riveters for decades of additional performance -- and thousands of dollars of savings -- compared to buying new. View our current stock of reconditioned riveters, or Contact National Rivet to discuss acquiring a reconditioned machine.

Safety Probe. A safety probe is an electrically actuated device that drops a ring from the upper-most position of the jaws and encircles the entire area under the driver when the machine is tripped. If there is any obstruction between the driver and the anvil (the operator’s fingers, for example), the machine will not cycle.
