Blind rivets principle introduction and specifications types

Blind rivets principle introduction and specifications types

Life, we need more and more accessories; we have come to understand that blind rivets is a class of single-sided riveting with rivets, shall use special tools - a riveting gun (manual, electric, pneumatic) for riveting, riveting the nail core is a particular riveting gun to pull, so that the riveting body continues to expand and play the role of riveting, is widely used in construction, automobiles, boats, airplanes, machinery, electrical appliances, furniture, and other products.

Blind Rivet Principle:

The blind rivet principle is achieved by pulling on the core head of the nail with the help of an inside-out force. To better apply blind rivets, first of all, a detailed understanding of the principle of blind rivets is needed.

1, blind rivets are one-sided, and they must use special tools - blind riveting tools (manual, electric, automatic) for riveting. These rivets are particularly suitable for the inconvenience of using ordinary rivets (must be riveted from both sides) of the riveting occasions and, therefore, are widely used in containers, construction, automobiles, ships, airplanes, machines, electrical appliances, furniture, and other products.

2, riveting is the use of a slightly smaller diameter than the perforation of the metal cylinder or metal tube (rivet) through the need to rivet the workpiece and the rivet on both sides of the face of the knock or pressure so that the metal column (tube) deformation and thickening at the same time in the formation of the ends of the rivet head (cap), so that the workpiece can not be disengaged from the rivets, in the case of the workpiece to make the separation of the external force, by the nail rod, the nail cap to withstand the resulting shear force, to prevent the separation of the workpiece.

3, open-type flat round head blind rivets are the most widely used; countersunk head blind rivets for performance need smooth riveting occasions; closed-type blind rivets when using the requirements with higher loads and have a certain degree of sealing performance of the riveting occasions.

4, riveting cold riveting and hot riveting; cold riveting is riveted at room temperature; hot riveting is used in connection with the requirements of higher places, such as iron bridge riveted steel beams; hot rivets need to preheat the rivets; hot rivets through the rivet holes, hit the head of the rivets, the contraction of the cooling process of the stress will make the connection more tightly.

Blind rivets specifications and types:

1, blind rivets according to different materials can be divided into aluminum alloy blind rivets, iron and stainless steel blind rivets three;

2, according to the different shapes of the nail head of the blind rivets, rivets can be divided into round-head blind rivets and countersunk head blind rivets two kinds;

3, according to the blind rivets, nail tube diameter size is divided into 2.4, 3.2, 4.0, 4.8, 6.4, (unit: mm); riveting cold rivets and hot rivets, cold rivets are rivets at room temperature; hot rivets are used to connect the requirements of higher places, such as iron bridge riveted to the steel beams, hot rivets need to rivets preheated red hot rivets penetrated riveting holes, hit the head of the rivets, the contraction of the stress in the cooling process will make the connection closer.

Blind rivets provide a wide range of rapid installation and relatively stable and reliable performance; the main advantages of using single-sided construction are a wide range of fast installation, clamping force, good seismic performance, and other benefits.
