Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zum Setzen von Nietelementen durch ein von einem Elektromotor angetriebenes portables Nietgerät, aufweisend eine Setzeinrichtung, bei dem die Kraft der Setzeinrichtung, mit der ein Nietelement gesetzt wird, anhand des von dem Elektromotor aufgenommenen Stroms überwacht wird, bei dem der Weg, den das Nietelement während des Setzvorgangs zurücklegt und/oder den die Setzeinrichtung während des Setzvorgangs des Nietelementes zurücklegt, durch wenigstens eine Sensoreinrichtung wiederholt gemessen wird, und bei dem zu jedem Messpunkt, die an dem jeweiligen Messpunkt aufgebrachte Kraft der Setzeinrichtung ermittelt wird und mit einem Referenzkraftwertebereich für den jeweiligen Messpunkt verglichen wird, wobei der Setzvorgang des Nietelementes qualitativ nicht akzeptiert wird, wenn an einem Messpunkt die an diesem Messpunkt aufgebrachte Kraft der Setzeinrichtung außerhalb des Referenzkraftwertebereiches für diesen Messpunkt liegt.
Abstract:
A hand-held riveting tool is driven by a battery-powered electric motor (26), and comprises a hydraulically-actuated riveting head (11), and a reciprocating hydraulic pump (22) driven by the electric motor. The tool includes a reservoir (23) for hydraulic fluid, the hydraulic supply line from the pump to the riveting head (11) being connected to the reservoir (23) by a reservoir inlet valve (29) which is normally open to allow hydraulic fluid to flow from the supply line into the reservoir (23). Operation of the tool-actuating trigger (31) firstly closes the reservoir inlet valve (29), and then switches on the electric motor (26) to operate the pump (22). Release of the tool-actuating trigger (31) firstly switches off the electric motor (26) to stop operation of the pump (22), and then opens the reservoir inlet valve (29). When the reservoir inlet valve (29) is closed by operation of the trigger (31), it acts as a pressure-relief valve to relieve over-pressure of hydraulic fluid.
Abstract:
The invention relates to a method for operating a hydraulic pressing device with a stationary part (26) and a moving part (24), whereby the moving part (24) is moved relative to the stationary part (26) until a predetermined pressure is reached. In order to operate a hydraulic pressing device of this type, for example a cable shoe (connecting) or riveting tool pressing device, whose handling is especially improved, the invention provides that the moving part (24) returns automatically and completely to the initial position thereof when a predetermined pressure is reached.
Abstract:
A blind rivet setting device which automatically feeds blind rivets into a rivet table (62), then sets the rivet (R) by pulling and detaching the mandrel (M). The rivet feed mechanism includes a thin strip or ribbon (150) of flexible material capable of holding the mandrel tips pierce/therethrough and evenly spaced apart. The strip (150) is drawn from a magazine (152a) for holding a quantity of blind rivets so connected to the strip (150) through a transverse feed slot (116) formed through the rivet table (62) generally orthogonal to the longitudinal axis of the device (10). A spring biased retracting device (156) continuously pulls the strip (150) through the feed slot (116) so that the next rivet in succession facing the rivet table (62) is automatically drawn into axial alignment within the rivet table (62) ready for positioning and setting into a work surface (W). A worn gear (132) with eccentric output (136) drives a connecting rod (138) for pulling and fracturing each mandrel (M) from the rivet body.
