Pop-nituri

Structura si terminologie Pop-niturile sunt compuse din doua parti: 1. Corpul nitului a) Capul nitului: partea superioara a nitului

Mandrina se rupe si partea detasabila se extrage cu scula de nituit.

Curba de nituire (relatia dinamica intre forta de apasare si cursa de impingere in cursul operatiei de nituire)

2. Mandrina a) Capul mandrinei: are rolul de a bomba corpul nitului in cursul operatiei de nituire, b) Punct de rupere: locul in care se produce ruperea mandrinei la incheierea operatiei de nituire. c) Parte utila: segmentul de mandrina care ramane incorporat in nit. d) Parte detasabila: segmentul de mandrina care se detaseaza prin rupere la incheierea operatiei de nituire.

Ruperea mandrinei

Materialele care se asambleaza sunt presate impreuna pana la atingerea limitei de rupere a mandrinei.

bombat tesit lat

Mandrina se impinge cu scula de nituit si aluneca in corpul nitului. Forta de apasare creste rapid pana cand capul mandrinei atinge corpul nitului.

b) Trunchi: are diverse lungimi in functie de grosimea materialelor care se asambleaza prin nituire.
