Abstract

A blind rivet setting device and method of setting a blind rivet. The device includes a housing; a pulling mechanism, arranged in the housing, that includes a chuck housing movable in a pulling direction and clamping jaws movable along a clamping distance in the chuck housing; an electric drive, structured and arranged to act on the chuck housing, that includes a control device; an electric battery structured and arranged as an energy source for the electric drive; and a spring structured and arranged in the chuck housing to apply a force to clamping jaws. For each clamping jaw, the chuck housing includes a guide path with a path base obliquely oriented to the pulling direction, and a back of each clamping jaw is supported against its respective path base over the clamping distance.
