Riv­et pro­duc­tion

A riv­et is one of the old­est types of fas­ten­ers. Even more than 2500 years ago, they were used in the man­u­fac­ture of mil­i­tary armor in Greece, Mace­do­nia. Of course, ancient riv­ets bear lit­tle resem­blance to mod­ern fas­ten­ers, but the prin­ci­ple of oper­a­tion is the same.

The next stage in his­to­ry, where the active use of the riv­et was not­ed, was the cen­tu­ry of the indus­tri­al rev­o­lu­tion of the late 19th and ear­ly 20th cen­turies. The cre­ation of steam engines, steel bridges and oth­er build­ing struc­tures used this type of fas­ten­er every­where. At this stage the riv­et had a steel core and a semi­cir­cu­lar head. Dur­ing instal­la­tion, the end of the rod was riv­et­ed, thus cre­at­ing an inte­gral con­nec­tion.

In this clas­sic form, the riv­et has been used for a long time, and in some places it is still used today. But progress does not stand still, so engi­neers con­stant­ly made attempts to improve the design. The improve­ment con­cerned pri­mar­i­ly the sim­pli­fi­ca­tion of the instal­la­tion method, because spe­cial tech­ni­cal devices are required to riv­et the rod of a clas­sic riv­et. In addi­tion, this method of instal­la­tion requires a two-sided approach to the fas­ten­er.

As a result, a new type was born — a blind riv­et. Its instal­la­tion requires only a one-sided approach, and it does not require sig­nif­i­cant efforts to fix it. You can install the blind riv­et man­u­al­ly using a sim­ple tool — a riv­et­er.

The design of a sin­gle-sided blind riv­et con­sists of two parts. The first part is the riv­et body itself, which includes the head and the tubu­lar rod. The sec­ond part is the rod that is insert­ed into the body. At one end of the rod there is an exten­sion that abuts against the end of the tubu­lar part. Dur­ing instal­la­tion, the rod is pulled out and crush­es the tubu­lar part, which, expand­ing, fix­es the riv­et.

Due to the ease of instal­la­tion, now this type of riv­et has almost replaced the clas­sic design. The main rule in the selec­tion of a mod­ern design is the cor­re­spon­dence of its length to the thick­ness of the parts to be fixed. The prin­ci­ple the longer the bet­ter does not work here. After all, the thick­en­ing can form before the fixed plane. In addi­tion, it is nec­es­sary to mon­i­tor the uni­for­mi­ty of the mate­ri­als of the riv­et and the parts in which it is installed. This rule is quite impor­tant, since gal­van­ic cor­ro­sion can lead to a loss of strength of the con­nec­tion or even its com­plete destruc­tion.

The mod­ern design also has high dec­o­ra­tive qual­i­ties. Paint­ed to match the col­or of the base mate­r­i­al, it becomes almost invis­i­ble.

You can buy riv­ets today at any con­struc­tion mar­ket or in a con­struc­tion hyper­mar­ket. But, for whole­sale deliv­er­ies, it is bet­ter to choose reli­able large deal­ers that rep­re­sent man­u­fac­tur­ing plants, we advise you to vis­it this site — http://www.rusbolt.ru/catalog/290/.
