Blind riveting tool, with a rivet pin ejection system, prevents pins being ejected into the ambient environment if a collection vessel is absent

摘要

The blind riveting tool (1) has a housing (2) for clamping pads to grip and pull a rivet pin (6) by a pull piston (10). A further piston, with a relative movement, is moved axially (7) by a central pressure sleeve (12) from a release setting to a clamping position. The tool has an ejection mechanism for the separated rivet pins and a collection vessel (38) for them working with a valve (36) to evacuate the working zone (18) which reverses the movement the pull piston if the collection vessel is not in place.
