Auf der dem Nietstößel 17 abgewandten Seite greift in die Lagerhülse 38 eine Setzdruckfeder 42 ein, die sich zum einen an dem Nietstößel 17 und zum anderen an einer der Lagerhülse 38 gegenüber liegenden Widerlagerplatte 43 abstützt.On the side facing away from the rivet ram 17, a setting pressure spring 42 engages in the bearing sleeve 38, which is located on the rivet ram 17 and the other on one of the bearing sleeve 38 opposite abutment plate 43 is supported.

Fig. 3 zeigt in einer Ansicht die die Vorlagekulisse 16 bildenden Vorlagekulissenschalen 28, 29 in einer Ansicht auf die dem Vorlagesteuerstift 32 zugewandte Innenseite. Aus der Darstellung gemäß Fig. 3 lässt sich deutlich entnehmen, dass die Vorlagesteuernut 37 über einen bei bestimmungsgemäßer Anordnung der Ausbrechkulisse 13 zugewandten Vorstehabschnitt 44 und einem dem Vorstehabschnitt 44 gegenüber liegenden Rückzugabschnitt 45 aufweist, zwischen denen sich spiralförmig verlaufende, stufenfreie Vorlageschrägabschnitte 46, 47 erstrecken. Fig. 3 shows in a view the template backdrop 16 forming master backdrop shells 28, 29 in a view of the template control board 32 facing inside. From the illustration according to Fig. 3 It can be clearly seen that the master control motor 37 has a projecting section 44 facing the breakaway gate 13 when the arrangement is intended and a retraction section 45 opposite the projecting section 44, between which extending, step-free template inclined sections 46, 47 extend.

Fig. 4 zeigt in einer teilgeschnittenen perspektivischen Ansicht die Druckkraftsensoreinheit 18 des Ausführungsbeispieles gemäß Fig. 1. Aus Fig. 4 ist ersichtlich, dass die in einem Lagerblock 48 angeordnete Druckkraftsensoreinheit 18 über eine Schiebehülse 49 als Schiebeteil verfügt, die in einer in dem Lagerblock 48 ausgebildeten Hülsenführung 50 in Längsrichtung verschiebbar angeordnet ist und mit einem Ende dem das Axialkraftvermittlungsteil bildenden Vorlagesteuerstift 32 gegenüberliegt. In dem dem Vorlagesteuerstift 32 abgewandten Ende der Schiebehülse 49 ist ein Druckstößel 51 in axialer Richtung festsitzend verankert, der über das der Vorlagesteuerhülse 32 abgewandte Ende der Schiebehülse 49 übersteht und mit einem in dem Lagerblock 48 fest verankerten Drucksensor 52 in Kontakt ist. Der Drucksensor 52 ist über eine Messwertwandler- und -verstärkereinheit an die Steuerelektronik 9 angeschlossen, die wiederum mit einer bei diesem Ausführungsbeispiel optisch wirkenden Freigabeanzeige 53 verbunden ist. Fig. 4 shows in a partially sectioned perspective view of the pressure force sensor unit 18 of the embodiment according to Fig. 1 , Out Fig. 4 It can be seen that the arranged in a bearing block 48 compressive force sensor unit 18 has a sliding sleeve 49 as a sliding part which is slidably disposed in a formed in the bearing block 48 sleeve guide 50 in the longitudinal direction and with one end facing the Axialkraftvermittlungsteil forming control pin 32. In the presentation control pin 32 facing away from the end of the sliding sleeve 49, a plunger 51 is firmly anchored in the axial direction, which protrudes beyond the template control sleeve 32 remote from the end of the sliding sleeve 49 and with a fixed in the bearing block 48 pressure sensor 52 is in contact. The pressure sensor 52 is connected via a Meßwertwandler- and amplifier unit to the control electronics 9, which in turn is connected to an optically acting in this embodiment release indicator 53.

Mit der Freigabeanzeige 53 ist ein Freigabesignal ausgebbar, sobald durch die über den Drucksensor 52 aufgenommene Andruckkraft eine Setzkraft erreicht oder überschritten ist. Diese minimale Andruckkraft entspricht einer vorbestimmten Setzkraft, die den Drucksensor 52 über eine mechanische Kraftflusskette, nämlich bei diesem Ausführungsbeispiel die Kulissensteuerung einschließend über den zu setzenden Spreizniet 1, die Kopfhülse 12, den Ausbrechsteuerstift 20, die Ausbrechkulisse 13, die Vorlageschaftstange 14, den Vorlagelagerring 30, den Vorlagesteuerstift 32, die Schiebehülse 49 und schließlich den Druckstößel 51 erreicht.With the release indicator 53, a release signal can be output as soon as a setting force is reached or exceeded by the pressure applied via the pressure sensor 52 pressing force. This minimal pressure force corresponds to a predetermined setting force, the pressure sensor 52 via a mechanical power flow chain, namely in this embodiment the slide control on the to be set Spreizniet 1, the head sleeve 12, the Ausbrechsteuerstift 20, the Ausbrechkulisse 13, the Vorstelleschaftstange 14, the template bearing ring 30, the master control pen 32, the sliding sleeve 49 and finally reaches the push rod 51.

Weiterhin ist mit der Freigabeanzeige zum Vermeiden von Überlastschäden ein Stoppsignal ausgebbar, sobald durch die über den Drucksensor 52 aufgenommene Andruckkraft eine maximale Setzkraft überschritten ist. Diese maximale Andruckkraft entspricht einer vorbestimmten maximalen Setzkraft, die den Drucksensor 52 über die mechanische Kraftflusskette erreicht. Ist die maximale Setzkraft überschritten, ergeht zum Vermeiden von Überlastschäden weiterhin ein Inhibierungssignal an die Steuerelektronik 9, mit dem das Auslösen eines Setzvorganges unterbindbar ist.Furthermore, with the release display to avoid overload damage, a stop signal can be output as soon as a maximum setting force is exceeded by the pressure applied via the pressure sensor 52 pressing force. This maximum pressing force corresponds to a predetermined maximum setting force which reaches the pressure sensor 52 via the mechanical power flow chain. If the maximum setting force is exceeded, an inhibition signal is issued to the control electronics 9 with which the triggering of a setting process can be prevented in order to avoid overload damage.
