Know: "Rivets"

Chinese name:

rivet

English name:

Rivet

definition:

A rod-shaped member with a cap at one end of the metal is inserted into the member to be joined, and the other end is punched and pressed at the outer end of the rod to press and fix the member.

In riveting, the parts of the riveted member are connected by self-deformation or interference. Rivets are many and varied.

Rivet type

Common rivets

Commonly used are semi-circular heads, flat heads, countersunk rivets, blind rivets, and hollow rivets, which are usually riveted pieces using their own deformation connection. (Usually less than 8 mm cold riveting, larger than the use of hot riveting.) But there are exceptions, such as the nameplate on the three-ring lock, is the use of rivets and the body of the rivet hole riveting.

Special rivets

There are also insert rivets, which are special. Divided into two parts, the thicker section of the cap body has a hole in the center, and the thinner part of the cap body is an interference fit. When riveting, the thin rod can be driven into the thick rod.

Rivet application

Semicircular rivets are mainly used for riveting occasions with larger lateral loads, and are most widely used.

Flat cone head rivets are used for riveting occasions such as hull and boiler water tank due to their large heads and corrosion resistance.

Countersunk head and 1200 countersunk rivets are mainly used for riveting applications where the surface must be smooth and the load is not large.

The semi-sinking and 1200 semi-sinking rivets are mainly used for riveting applications where the surface must be smooth and the load is not large.

Flat head rivets are used for riveting applications with normal loads.

The flat head and flat head rivets are mainly used for riveting occasions of non-metal materials such as metal sheets or leather, canvas, and wood.

Large flat head rivets are mainly used for riveting occasions of non-metallic materials.

Semi-tubular rivets are mainly used for riveting applications with little load.

Headless rivets are mainly used for riveting applications of non-metallic materials.

The hollow rivets are light weight and have weak nail heads. They are used for riveting occasions of non-metallic materials with small loads.

Tubular rivets are used for non-load riveting applications of non-metallic materials.

Signage rivets are mainly used for riveting machines, equipment and other nameplates.

Blind rivets are a type of rivets used for riveting on one side, but they must be riveted using a special tool—a riveter (manual, electric, or dynamic). This type of rivet is particularly suitable for riveting occasions where it is inconvenient to use ordinary rivets (to be riveted from both sides), so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products. Among them, the open type blind head blind rivets are most widely used, and the blind rivets are suitable for occasions where the performance requires smooth riveting. The blind type blind rivets are suitable for riveting occasions requiring higher load and certain sealing performance.

The hitting rivet is another kind of rivet riveted on one side. When riveting, hit the rivet head with a hammer to expose the mandrel so that it is flush with the end surface of the nail head. This completes the riveting operation, which is very convenient, especially suitable for inconvenience. Rivets with ordinary rivets (to be riveted from both sides) or blind rivets (lacking the riveter). Normally, flat round heads are used for riveting, and countersunk rivets are used for occasions where smooth riveting is required.

Some rivets can also be worn on clothing. Become a popular element today.
