Aircraft and Aerospace Applications
One of the most extensive uses of rivets is in the aircraft and aerospace industries. Rivets provide strong, reliable mechanical fastenings for the thin sheets of aluminum that compose the outer skin or fuselage of an aircraft. Hundreds of thousands of rivets are used to assemble the frame and skin of both commercial and military aircraft. Rivets allow for light construction while providing joints with shear and tensile strength to handle flight stresses and engine vibration. Aircraft technicians do extensive riveting work both in manufacturing and repairing airplane structures. Certain aircraft use advanced structural rivets with high-strength aluminum or titanium construction.
Rivets are also ubiquitous in spacecraft construction including rockets, satellites, and space stations. The external skin and internal structure rely on riveted connections to withstand the forces and conditions of spaceflight. Aerospace rivets need to maintain their strength in the temperature extremes of space as well as during intense vibration such as launch. Technicians assembling satellites and other space vehicles routinely install thousands of rivets.
Industrial and Commercial Applications
Beyond aerospace, rivets play an integral role in the fabrication of trucks, trains, ships, buildings, bridges, and many other structural frames. The manufacture of heavy equipment, including bulldozers, cranes, and tractors relies on rivets to assemble durable exterior components. Truck cabs and trailers use rivets to join exterior panels because they allow the sheets to flex and absorbs road shock and vibration. Rivets provide reliable fastening strength for rail cars, ocean vessels, storage tanks, and cargo containers exposed to harsh conditions. Steel buildings and metal bridges employ rivets for structural connections because of their combination of strength, longevity, and ease of inspection.
Many common household and outdoor products utilize rivets in their construction. Patio furniture, ladders, outdoor sheds, recreational vehicles, playground equipment all take advantage of riveted assembly. Storage racks, filing cabinets, kitchen utensils and various tools rely on rivets for durability in their exposed mechanical joints. Most jeans have rivets at points of strain to reinforce the material during movement. Even items like inexpensive jewelry and leather goods often use small ornamental rivets for decoration and fastening. The wide availability and low cost of basic rivets allow them to economically fasten mass-produced consumer goods.
Repair and Maintenance Applications
Both professionals and handy homeowners rely on rivets for diverse repair and maintenance projects. Mechanics drill out damaged or worn rivets and install replacements to fix issues on vehicles, machinery, aircraft, and boats. Loose rivets on truck bodies and trailers easily shear off from road stresses, requiring ongoing rivet replacement to prevent further damage. Construction workers and crane operators reinforce structural connections by adding rivets. Plumbers use special copper rivets to permanently join pipes, valves, and elbow joints. Homeowners utilize rivets for repairs on swing sets, tools, appliances, gates, furniture and numerous other items. The permanence and strength of a riveted connection makes rivets a first choice for repairs.
Industrial Riveting Techniques
Production factories doing extensive riveting have specialized techniques and machinery. Pneumatic rivet guns of various types efficiently and consistently set rivets faster than manual riveting. automated machines precision place and set rivets for mass-production. Assembly lines may use vibratory bowl feeders to orient and deliver large quantities of rivets to operators. Robotic riveting cells are programmed to drill holes and install rivets with high speed, accuracy and consistency. Industrial shops may use heat treating or age hardening processes to increase the strength of installed rivets. Testing machines verify the clamp load and shear strength of sample rivets from production runs. Industries doing large volume riveting rely on sophisticated tools and processes for optimal results.
One-Sided Blind Rivets
Traditional rivets require access to both sides of a joint, which limits applications with enclosed spaces. Blind rivets were developed to allow riveting from one side or where backing material cannot be used. Blind rivets have a hollow body and extrudable mandrel allowing the rivet to be inserted and set from one side. The mandrel is pulled to expand the body, locking the rivet in place without a bucked tail. Blind rivets see wide use in auto, appliance, electronics and HVAC manufacturing where only one side is accessible. Pop rivets are a common type of blind rivet designed for quick manual installation without special tools. Blind rivets greatly expand the utility of rivets for both manufacturing and repairs.
Rivets have proven their versatility and reliability for thousands of years in structures both large and small. The unique abilities of rivets to provide permanent fastening in thin materials ensure their continued popularity from aircraft to zippers. Ongoing rivet innovations such as high-strength alloys and blind types expand potential applications. Whether in delicate scientific instruments or massive ships and bridges, rivets deliver the durability to hold mechanically assembled objects together for generations. This brief overview shows that rivets continue to be an integral fastening technology supporting our infrastructure and means of transportation. CNC Milling CNC Machining
