Welcome to Cherry

Each fire-breathing behemoth they mass-produced in sprawling plants used thousands of loose rivets. Boilermaking, a key step in steam locomotive assembly, was a very slow, laborious process that required a team of highly skilled assemblers.

He placed the rivet in a hole and backed it up while a worker on the outside of the boiler hammered or peened the rivet head. While locomotive boilermaking and rivet throwing are archaic skills today, riveting remains one of the most effective fastening methods. However, other tools and techniques, such as threaded fasteners, welding and adhesive bonding, are more commonly used to create joints. Assemblers generally want to eliminate the use of traditional, loose rivets.

Whenever possible, they prefer to use studs or bosses that are cast or otherwise formed in one of the parts. As a result, new processes and tools, such as orbital riveting, radial riveting, blind rivets and self-piercing rivets, have become more popular in recent years. But, loose rivets still offer numerous benefits to assemblers, such as simplicity, dependability and relatively low cost. In fact, loose rivets are still the fasteners of choice for assembling products such as brake shoes, medical instruments, seatbelt retractors, scissors, pliers, air bag assemblies, door hinges, toggle clamps, pulleys, caster wheel assemblies, furniture mechanisms, staplers, chainsaws and garden tools.

Rivets are ideal for flexible joints or tightly joined mating components. They are an inexpensive alternative to threaded fasteners, especially for products that require pivot joints or mechanical repetitiveness.

Jackson, MI. He believes assemblers should consider using loose rivets whenever products can benefit from the cost savings of the fastener itself and overall assembly cost. Loose rivets generally cost several cents less than threaded fasteners. It allows high production rates, it is a permanent fastener, it can be used on assemblies of varying complexities, it is easy to inspect and it requires no maintenance.

Additional benefits include fastener strength, product strength after riveting and a clean fastening process. In fact, disassembly usually destroys rivets. With solid rivets, the formed shape is produced by heading over, hammering or spinning the solid end of the shank. With tubular rivets, the formed shape or clinch is produced as the material around the edge of a hole in the end of the shank is rolled over against the surface of one of the pieces being joined.

How Rivets Work A rivet is an unthreaded, headed pin used to join two or more parts by passing the pin through holes in the parts and then forming a second head in the pin on the opposite side. A head is formed on the plain end of the pin by hammering or by direct pressure. Once the rivet has been deformed, it cannot be removed except by breaking one of the heads. There are three methods of riveting: compression, impact and nonimpact. In the compression method, the head of the rivet is formed by pulling or squeezing the rivet shank.

In the impact method, the head is formed by the force of the impact against the top of the shank. In nonimpact riveting, the rivet head is formed by a rolling or spinning action against the top of the shank.

A combination of impact and compression can also be used. Rivets are used primarily for lap joints. However, McNaughton says the clearance hole into which the rivet is inserted must be close to the diameter of the rivet.

Unlike some other types of fasteners, rivets swell up in the hole and provide extra support. In solid impact riveting, a compressive axial load is applied to the end of the rivet shank.

This causes the rivet shank to swell throughout its length as it shortens under the load. The rivet shank continues to expand until the hole in the parts being assembled restricts it from further expansion. The unrestricted rivet end then expands, forming the rivet clinch. Because of the forged grain structure of rivets, they have higher compression and shear strengths than many other mechanical fasteners.

But, rivets are not recommended for transmitting loads in tension. Their tensile and fatigue strengths are lower than those of bolts. Permanent failure may result when loads exert movements that cause a prying action on the head of a rivet. Tensile load stress should be kept at a minimum when using rivets. Rivet Options Loose rivets can be either solid, tubular or semitubular.

Which fastener to use depends on issues such as stress and shearing. For strength and durability, solid rivets work the best. Semitubular rivets are recommended when strength is somewhat of an issue, but ease of curling is also important. Tubular rivets are the best choice for light-duty applications. Solid rivets are often used in applications where extremely high joint strength is required, such as aircraft landing gear, automobile brake shoes, or mining and construction equipment.

Typical solid rivets include flat head, pan head, round head and shoulder-type rivets. The head may be of various shapes, but the shank must be of sufficient length to accommodate the thickness of the parts to be joined and to allow for the formation of the clinch head. Flat head, pan head and button head rivets are often used for tightly joining mating components. A shoulder rivet is a solid or tubular rivet that has a shoulder under its head.

Shoulder rivets are typically installed so the shoulder acts as a bearing surface, allowing the retained part to pivot. Shoulder-type rivets are normally used for pivoting or hinging joints. A tubular rivet has a coaxial cylindrical or tapered hole in the headless end. It is secured by splaying or curling the end. To be classified as tubular, a rivet must have a hole depth that exceeds percent of the mean shank diameter.

Tubular rivets are ideal for light-load products that have very few strength requirements, such as electronic components. A semitubular rivet is a rivet with a hollow end whose hole depth does not exceed percent of the rivet body diameter. It requires much less insertion force and allows longer rivets to be used without buckling of the rivet shank.

Rivet insertion force is typically less than 40 percent of that required for a solid rivet of the same shank diameter and material. The ability to easily curl the rivet is one of the biggest advantages of using semitubular rivets. Two of the most common types of steels used in rivet manufacturing are SAE and B Brass, nickel silver, bronze, copper, stainless steel and aluminum alloys are also widely used. On this type of rivet, the formed closure is usually ragged around the edge and has a poor appearance.

They are typically more expensive than steel rivets and are used to join plastic to plastic, plastic to metal or fiberglass to fiberglass. Plastic rivets are ideal for nonconductive applications or noncorrosive environments. Riveting Methods Standard rivet setting equipment ranges from small, handheld rivet guns to large rivet machines. Selection criteria depends on the types of rivets being used and the types of material being joined.

For instance, solid rivets generally require more powerful machinery, such as a 1-ton pneumatic press. Handheld, hydraulic or pneumatic rivet guns are typically used for applications that require versatility, such as assembling products in tight or confined spaces. Pliers-like manual rivet setters are available for low-volume or custom applications, such as bookbinding.

Rivet machines include single- and double-spindle automatic riveters, multiple machine systems and automated riveting systems. The single-spindle automatic machines are the simplest, most popular riveters. They are very flexible and can be mechanically, hydraulically or pneumatically operated. Machines equipped with monitors and sensors can track vital information, such as the amount of force put on a rivet.

They also can indicate whether a rivet is too short or too long and too hard or too soft. Riveting Tips Assemblers can maximize their use of loose rivets by following a few basic tips. In fact, as long as its shank length is sufficient, a rivet can fasten as many parts at one point as necessary.

When two parts of different thickness are riveted together, the rivet head should be placed against the thinner part and the rivet clinch against the thicker part. When two parts of different materials, such as plastic to steel, are riveted together, the rivet head should be placed against the softer part and the rivet clinch against the harder part. As a rule of thumb, the greatest shank expansion of the rivet during forming will be on the clinch side of the rivet.

According to Anderson, this expansion will reduce the possibility of part distortion. This website requires certain cookies to work and uses other cookies to help you have the best experience. By visiting this website, certain cookies have already been set, which you may delete and block.
