Riveting a nail-shaped object with a cap on one end: in riveting, a riveted part connected by its own deformation or interference.There are many kinds of rivets and they are informal in form.
Types and applications of rivets:
Commonly used are R type rivet, fan rivet, blind rivet, tree rivet, half round head, flat head, half hollow rivet, hollow rivet, solid rivet, countersunk head rivet, blind rivet, these are usually using their own deformation to join the rivet.Generally less than 8 mm with cold riveting, larger than this size with hot riveting.But there are exceptions, such as some locks on the nameplate, is the use of rivet and lock hole interference rivet.
R – type plastic rivet, also known as expansion rivet, is composed of plastic nail and mother button.The mounting base is placed in a smooth hole without the use of mounting tools, and then the head is pressed down. The specially designed foot expands and expands after being stressed, and is firmly locked on the mounting surface.It is often used to connect plastic shell, light plate, insulation material, circuit board, or any other light, light material, beautiful and practical, easy to use.
Fan rivets are specially designed for manual installation and can be pulled in through the holes in the panels or underframe. They are made of elastomer material with good toughness and can be quickly installed even in interference assembly.The fan rivet is mainly used for fixing between electronic computer chassis fan, heat sink and chip, which has the function of elasticity and the corresponding aperture. It is anti vibration and reduce noise.
Rivets are new riveting fasteners which are very convenient for riveting. Rivets can show their unique advantages in a relatively narrow space or in an environment where riveting guns are not available or cannot be used.Two or more connectors can be riveted successfully by using hammer and other objects to hit the nail core on one side.According to the shape of the cap brim, the rivets can be divided into flat head rivets and countersunk head rivets. According to the different material combination, they can be divided into all aluminum rivets, aluminum steel rivets, all stainless steel rivets, steel steel rivets, aluminum stainless steel rivets, plastic rivets and so on.Rivets do not have to use manual rivet or pneumatic rivet like the rivet to rivet, with better riveting property and convenience, can be widely used in all kinds of rivet joints.
Plastic tree rivet is also called the inverted tooth plastic rivets are called Christmas tree plastic rivets, tooth type flake good flexibility to the interference in the assembly of round hole directly manual press installation, tooth type plate can adjust itself according to the thickness of the actual size to fixed, inverted tooth design is the rivet installation after be installed firmly fixed on the surface, not easy to be pulled out, suitable for bubble, timber, rubber, automotive interior and other soft materials between regular use.Plastic tree rivet has excellent insulation, fire resistance, non-magnetic, heat insulation, light weight, high temperature resistance, high strength, corrosion resistance, widely used in various industrial fields.
The type of blind rivets can be roughly divided into open type blind rivets, closed type blind rivets, single and double drum blind rivets, wire drawing blind rivets, seahorse nails, waterproof lantern rivets, etc., blind rivets are a kind of single rivet, but must use special tools — pull rivet gun (manual, electric, pneumatic) for riveting.This kind of rivet is especially suitable for the occasions where it is inconvenient to use common rivet (must be riveted from both sides), so it is widely used in construction, automobile, ship, airplane, machine, electric appliance, furniture and other products.The following is a brief description of each model.
Countersunk head type rivet: riveting for riveting parts with smooth and beautiful surface.
Drum rivet: when riveting, the nail core will pull the end of the rivet nail body into a single or double drum shape, the two structure to be riveted clamped, and can reduce the pressure acting on the surface of the structure.Application: mainly used for riveting various thin structural parts of vehicles, ships, construction, machinery, electronics and other industries.
Large cap rivet: compared with the common rivet, the aluminum cap diameter of the rivet is significantly larger. The rivet has a larger contact area and a stronger supporting surface when riveted with the joint, which can enhance the torque strength and withstand higher radial tension.Applicable industry: suitable for fastening soft, fragile surface material and oversize hole. Increased diameter of cap brim has special protection application for soft material.
Closed type rivet: designed to cover mandrel head after riveting, suitable for many applications with waterproof requirements.High shear, anti – vibration, anti – high pressure.Suitable for riveting occasions requiring high load and certain sealing performance.
The nail body of the whole aluminum rivet is also made of high quality aluminum wire, beautiful and durable after riveting will never appear rust phenomenon: compared with the common rivet, rivet rivet rivet rivet strength is lower, suitable for soft materials of the joint.
Stainless steel open rivets: the rivets are the best choice for high tensile strength and corrosion resistance.
The semi – circular head rivet is mainly used in riveting occasions with large transverse load.
The flat taper head rivet is corrosion resistant due to the hypertrophy of the nail head, and is often used in riveting occasions with strong corrosion, such as ship hull and boiler water tank.
Flat head, flat head rivets are mainly used for metal sheet or leather, canvas, wood and other non-metallic materials riveting occasions.
The large flat head rivet is mainly used for riveting non-metallic materials.
The semi – hollow rivet is mainly used for riveting with small load.
The headless rivet is mainly used for riveting non-metallic materials.
The hollow rivet is light in weight and weak in nail head, which is used for riveting non-metallic materials with small load.
Tubular rivets are used to rivet nonmetallic materials without load.
Label rivets are mainly used for riveting machines, equipment and other above the nameplate.
Some rivets can also be matched in clothing, becoming a popular element today, and most of them are the representatives of punk style.
There is also a pair of rivets, more special.It is divided into two parts, the thicker part with a hole in the center, and the thinner part with a cap body is interference fit.When riveting, drive the thin rod into the thick rod.
Rivet development History:
The earliest rivets were small bolts made of wood or bone, and the earliest metal variants were probably the ancestors of the rivets we know today.There is no doubt that they are metallic connection method of the oldest known to mankind, can be traced back to the original use wrought metal so far, for example: the Bronze Age the egyptians used rivet type slotted wheel perimeter of six wooden door riveting fastening together, form the greeks after successfully cast in bronze statue of large, reoccupy rivet riveting components together.
In 1916, when H. V. White of the British Aircraft Corporation first patented blind rivets that could be riveted to a single side, little could have been expected that the rivets would become so widely used today.From aerospace to office machines, electronic products and sports equipment, blind rivets have become an effective and stable method of mechanical connection.
Hollow-rivets were mostly invented for the manufacture or maintenance of harness equipment. It is not clear exactly when hollow-rivets were invented, but harness was invented in the 9th or 10th century AD.Riveted rivets, like nailed hoofs, freed slaves from heavy labor, and rivets led to many important inventions, such as iron pliers for copper and iron workers and sheep-shearing blades.
