Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylinder (geometry), cylindrical shaft with a head on one end. The end opposite the head is called the ''tail''. On installation, the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support Tension (physics), tension loads. However, it is much more capable of supporting Shear force, shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term ''rivet'' was introduced and, where they are remembered, are usually classified among nails and bolts respectively. History Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archeology, archaeological findings dating back to the Bronze Age. Rivet ...

Rivet Gun
A rivet gun, also known as a rivet hammer or a pneumatic hammer, is a type of tool used to drive rivets. The rivet gun is used on rivet's ''factory head'' (the head present before riveting takes place), and a bucking bar is used to support the tail of the rivet. The energy from the hammer in the rivet gun drives the work and the rivet against the bucking bar. As a result, the tail of the rivet is compressed and work-hardened. At the same time the work is tightly drawn together and retained between the rivet head and the flattened tail (now called the ''shop head'', or buck-tail, to distinguish it from the factory head). Nearly all rivet guns are pneumatically powered. Those rivet guns used to drive rivets in structural steel are quite large while those used in aircraft assembly are easily held in one hand. A rivet gun differs from an air hammer in the precision of the driving force. Rivet guns vary in size and shape and have a variety of handles and grips. Pneumatic rive ...

Fastener
A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel. Other methods of joining materials, some of which may create permanent joints, include: crimping, welding, soldering, brazing, taping, gluing, cement, or the use of other adhesives. Force may also be used, such as with magnets, vacuum (like suction cups), or even friction (like sticky pads). Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general-purpose fasteners. Furniture supplied in flat-pack form often uses cam dowels lock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riveting Machines
A riveting machine is used to automatically set (squeeze) rivets in order to join materials together. The riveting machine offers greater consistency, productivity, and lower cost when compared to manual riveting.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 30, Cypress, CA, 2013. ISBN 978-0-9897906- 0-4. Types Automatic feed riveting machines include a hopper and feed track which automatically delivers and presents the rivet to the setting tools which overcomes the need for the operator to position the rivet. The downward force required to deform the rivet with an automatic riveting machine is created by a motor and flywheel combination, pneumatic cylinder, or hydraulic cylinder. Manual feed riveting machines usually have a mechanical lever to deliver the setting force from a foot :wikt:pedal, pedal or hand lever. Riveting machines can be subdivided into two broad groups — impact riveting machines and orbital (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanic
RMS ''Titanic'' was a British ocean liner that sank in the early hours of 15 April 1912 as a result of striking an iceberg on her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, approximately 1,500 died (estimates vary), making the incident one of the deadliest peacetime sinkings of a single ship. ''Titanic'', operated by White Star Line, carried some of the wealthiest people in the world, as well as hundreds of emigrants from the British Isles, Scandinavia, and elsewhere in Europe who were seeking a new life in the United States and Canada. The disaster drew public attention, spurred major changes in maritime safety regulations, and inspired a lasting legacy in popular culture. It was the second time White Star Line had lost a ship on her maiden voyage, the first being in 1854. ''Titanic'' was the largest ship afloat upon entering service and the second of three s built for White Star Line. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AISC
The American Institute of Steel Construction (AISC) is a not-for-profit technical institute and trade association for the use of structural steel in the construction industry of the United States. AISC publishes the Steel Construction Manual, an authoritative volume on steel building structure design that is referenced in all U.S. building codes. The organization works with government agencies, policymakers, and other stakeholders to promote policies and regulations that support the industry's growth and development. History Foundation In 1911, two civil engineering organizations, the Bridge Builders Society and the Structural Steel Society, began cooperating to form broad codes of ethics and practices within the profession. In 1917, during World War I, the two groups merged into the War Service Committee which helped procure fabricated structural steel and coordinate industry efforts. However, by 1919 the Committee was disbanded but some steel fabricators insisted on creating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ball-peen Hammer
A ball-peen or machinist's hammer, is a type of peening hammer used in metalworking. It has two heads, one flat and the other, called the peen, rounded. It is distinguished from a cross-peen hammer, diagonal-peen hammer, point-peen hammer, or chisel-peen hammer by having a hemispherical peen. Etymology In the word "ball-peen", ''peen'',. probably comes from a North Germanic source; compare dialectal Norwegian ("peen"), Danish ("peg"), German ("the peen of a hammer"), Old Swedish ("to pound iron with a hammer"). Uses Besides peening (surface-hardening by impact), the ball-peen hammer is useful for many tasks, such as striking punches and chisels (usually performed with the flat face of the hammer). The peening face or ball face is useful for rounding off edges of metal pins and fasteners, such as rivets. It can also be used to make gaskets for mating surfaces: a suitable gasket material is held over the surface that needs a gasket, and the operator lightly taps a ...

Tongs
Tongs are a type of tool used to grip and lift objects instead of holding them directly with hands. There are many forms of tongs adapted to their specific use. Design variations include resting points so that the working end of the tongs does not come into contact with a bench surface. The first pair of tongs belongs to the Egyptians. Tongs likely started off as basic wooden tongs and then over time progressed to bronze bars as early as 3000BC. Over time they progressed to what we now know as modern-day tongs. An Egyptian wall painting from 1450 BCE shows a crucible supported between two metal bars. # Tongs that have long arms terminating in small flat circular ends of tongs and are pivoted at a joint close to the handle used to handle delicate objects. Common fire-tongs, used for picking up pieces of coal and placing them on a fire without burning fingers or getting them dirty are of this type. Tongs for grilling, and tongs for serving salad or spaghetti are kitchen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
