2 Tutorial: Engineering technology Topic: Rivet joints Prepared by: Ing. Jaroslav Hábl Projekt Anglicky v odborných předmětech, CZ.1.07/1.3.09/ je spolufinancován Evropským sociálním fondem a státním rozpočtem České republiky.

3 RIVET JOINTS  Rivet joint is non-dismountable joint with the shape contact.  It is made by permanent rivet deformation or one of connected parts.  Rivet joint is not capable to provide exact position of connected parts.  Presently, rivet joints are mostly replaced by welded joints.  They are mainly used in such areas where it is not possible to apply other technologies (e.g. aviation)

4 TYPES OF RIVETS a) With semi-ball shaped head, b) with flat semi-ball shaped head, e) With flat head, f) drilled, g) boiler´s, h) shipping, closed, l) split, m) hollow with mandrel

5 DIRECT RIVETING Direct riveting – one of the components is riveted in another.

6 INDIRECT RIVETING Indirect riveting – for joining parts is used independent riveting connection.

7 TYPES OF RIVET JOINTS According to the number of cross-sections, where rivet cutting can happen, rivet joints are divided into: - one-cutting - two-cutting

8 MANUAL RIVETING Closing headChecknut Closing little head Supporting head Rivet shank Supporting little head Rivet lengthAllowance Gripping length Manual riveting

9 RIVETS WITH MANDREL 1 Mandrel with rivet 2 Fixed to riveting pliers 3 Mandrel stretches rivet and it tears 4 Rivet is seated

10 Calculation of rivet joint Choice of rivet diameter: d = 2s for s ≤12 mm, d = s + 10 for s>12 One-cutting rivets: Slide: F ≤ n ⋅ A⋅τD,s where A = π. d2 / 4 Imprint: F ≤ n ⋅ A⋅ pD where A = d. s Two-cutting rivets: Slide: F ≤ n ⋅2A⋅τD,s where A = π. d2 / 4 Imprint: F ≤ n ⋅ A⋅ pD where A = d. s

12  Write down the types of rivets.  What is the difference between direct and indirect riveting.  Draw the rivet with mandrel.
