摘要:
The present invention relates to a blind rivet and blind rivet removal system and related method. Once set the blind rivet is not normally removed. However, increasingly removal is required due to the need to recycle automobiles. In order to remove blind rivets it has been necessary to remove the rivet flange by a variety of methods. Generally these methods were ineffective due to the resistance afforded by the mandrel and the risk of damage to the application or workpiece. Removing this unwanted swarf and debris often proved difficult. The invention provides a rivet with a stepped flange and a rivet removal tool with clips adapted to fit between the flange and surface of a workpiece so that upon relative displacement of the clips a rivet is extracted in a substantially axial direction as a single item. The invention also includes a tool and related method of blind rivet removal.
