Abstract:
1. A device for setting fastening elements, comprising: a rivet ram; a feed shaft rod including a feed control pin protruding radially outwardly from said feed shaft rod, said feed control pin fixed relative to said feed shaft rod and operable upon rotation of said feed shaft rod to effect axial movement of said feed shaft rod between a retracted, starting position and an advanced, setting position; a drive unit operable to rotate said feed shaft rod; at least one link and a link control having a set control pin associated with at least one of said links and via, which, when said feed shaft rod is rotated, said rivet ram is movable between a retracted, pre-installation position and an advanced, installation position; and a pressure force sensor unit including a pressure sensor and at least one axially displaceably mounted sliding sleeve disposed between said pressure sensor and said feed control pin, said sliding sleeve disposed within a sleeve guide formed within a bearing block; said feed shaft rod and said rivet ram coaxially aligned along a first axis, and said feed control pin, said sliding sleeve, and said pressure sensor engageably aligned with one another along a second axis, said second axis offset and parallel to said first axis; and wherein, in a setting position of said feed shaft rod, said feed control pin can be acted upon by an axial pressing force exerted on said feed shaft rod to engage said feed control pin with said sliding sleeve and said sliding sleeve engaging said pressure sensor to transmit force from said feed shaft rod to said pressure sensor along an axial direction.
