![]() ![]() At that time, the most controversial point was to abandon traditional steel bars and cement, and use building materials such as steel frame materials and rivets. The body of the tower is built with a hollow steel frame, using a total of 7,300 tons of steel, 12,000 metal parts, and 2.5 million rivets. It took two years, two months and three days to build. It was also the tallest building in the world at that time. It is unclear exactly when the hollow rivet was invented, but horse harnesses using hollow rivets were invented in the 9th or 10th century AD.ĭo you know what is the most famous steel structure building in the world? There is no doubt about the answer - the Eiffel Tower in Paris, France! This steel tower building covering an area of about 10,000 square meters was built as a symbol of the World Expo in 1889. Since then, blind rivets have been widely used in mechanical connections of aerospace, office machines, and electronic products. Hollow rivets In 1916, H.V White of the British aircraft manufacturing company obtained the patent for blind rivets that can be riveted on one side for the first time. After the Greeks successfully cast large statues in bronze, they used rivets to fasten the parts together. In the Bronze Age, the Egyptians used rivets to fasten the six wooden sectors on the outer line of the slotted wheel. They are the oldest method of joining metals known to man, dating back as far back as the original use of malleable metals. ![]() The earliest rivets were small pegs made of wood or bone, and the earliest metal deformations may be the ancestors of rivets. Today, Tuofa CNC Machining introduces the development history, process concept, type, application scenarios and selection strategies of rivets. They are often used in riveting and maintenance of closed parts of aircraft.ģ Processes and Characteristics of RivetingĪ rivet is a mechanical fastener, a rod-shaped part with a cap at one end, after penetrating the connected component, the other end is pressed out at the outer end of the rod, and the component is pressed and fixed. They can be used for the connection of aluminum alloys, structural steels, and composite materials. Rivets have high reliability, high connection strength, long life, and easy operation and use. Rivet is not only a tool or a material, it can play a pivotal role in many industries.įor example, various industries such as housing construction and machine manufacturing need rivets to fasten some parts, so the rivets should be fastened as they do, which is related to the quality and development of each industry using rivets, work efficiency and use safety. ![]()
