<p>The riveting device consists of a piston cylinder thrust unit (11,12) with a second hydraulic piston cylinder device (9,18) for transmission of the power to the rivet. The hydraulic fluid is contained in a cylinder shaped space and is moved to an fro via a displacement psiton (17) itself dependent upon the movements of the other two pistons. The transmission of the power is brought about by the fact that the displacement piston dia. is small in relation to the other two pistons.</p> |
