Rivets are a kind of metal stamping component, which are nail-shaped objects used to connect two parts or components with a through hole and there is a cap at one end. It is also a kind of fastening hardware parts. Maybe some people don't know more about it, and they don’t know how to choose the right materials for rivets. This article will share with you some knowledge about it for your reference.
The material of rivet
Generally, the mechanical properties of rivets metal parts should be same with the parts you will join. We know that rivets are made of different materials, which include copper, iron, aluminum, stainless steel, alloys and so on. Copper rivet parts use their own deformation or interference to connect the riveted metal parts in the riveting process. Common rivet parts used in daily life include round head rivets, flat head rivets, countersunk rivets, semi-tubular rivets, solid rivets, sub-rivets, step rivets and so on.
The rivet top bar can be made of tungsten alloy material. Tungsten alloy rivet top bars provide the maximum usable density. The edges and corners of the rivet top bar are smoothed, and the working surface is polished to facilitate use. This helps to place the deformed depressurizing tail. Please note that you cannot use a vise to clamp the rivet top bar, unless the jaws of the vise are equipped with a protective cover to prevent damage to the rivet top bar.
What are the types and functions of rivets?
In daily life, the types of rivet parts include R-shaped rivets, fan rivets, blind rivets, tree rivets, semi-tubular rivets, solid rivets, countersunk rivets, hollow rivets etc. which are usually used the self-deformation to connect the riveted pieces. Generally, cold riveting part is used for those smaller than 8 mm, and hot riveting part is used for those larger than this size. But there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the hole of the lock body.
R-shaped plastic rivets are also called expansion rivets, which are composed of plastic nails and female buckles. It does not need to use installation tools during installation. Place the installation base in a smooth hole, and then press the head. The specially designed foot expands after being stressed, and then it is firmly locked on the surface installed. It is often used to connect plastic shells, lightweight plates, insulating materials, circuit boards, or any other thin, light-weight materials, beautiful and practical, and it is easy to use.
The fan rivets are specially designed for manual installation. They can be pulled in through the holes of the panel or the bottom frame. It is made of elastic material and has good toughness. It can be installed quickly even in interference assembly. The design is ingenious and flexible, and the corresponding aperture is not easy to slide out after being pulled in. The fan rivet is mainly used for fixing between the fan, heat sink and chip of the electronic computer case, which is anti-vibration and reduces noise.
