Description
Schutzvorrichtung für Blechscheren Es fehlt bei Blechscheren bisher noch eine Schutzvorrichtung, die den Raum zwischen dem Blechhalter und dem Scherentisch zuverlässig abdeckt, damit der Arbeiter beim Niedergang des Einrückgestänges vor dem Schnittbeginn nicht nur daran gehindert wird, seine Finger noch im letzten Augenblick an die Messer heranzubringen, sondern auch die teilweise schon durchgesteckten Finger noch geschützt werden. Gemäß der Erfindung wird eine solche Schutzvorrichtung durch die Anordnung einer mit dem Niedergang des Einrückgestänges gegen den Arbeiter ausschwenkenden Leiste geschaffen, die die Hand zurückhält oder zurückschiebt.Protective device for tin snips Up to now, tin snips have been missing Another protective device that covers the space between the sheet metal holder and the scissor table reliably covers so that the worker is in front of the lowering of the engagement linkage the start of the cut is not only prevented from holding his fingers at the last moment to bring them to the knife, but also the fingers that have already been pushed through still to be protected. According to the invention, such a protective device is by the arrangement of one with the companionway of the engaging linkage swinging out against the worker Bar created that holds back or pushes back the hand.
Damit auch durch die Sichtöffnungen des Blechhalters kurz vor dem Schnitt keine Gliedmaßen mehr hindurchgesteckt werden können oder bereits darin steckende Glieder zwangsläufig wieder zurückgeschoben werden, sind gemäß der Erfindung in den Blechhaltersichtöffnungen zusätzliche Klappen angeordnet, die beim Niedergehen des Einrückgestänges die Sichtöffnungen abdecken.So also through the viewing openings of the sheet metal holder shortly before the Cut limbs can no longer be pushed through or are already in them stuck members are inevitably pushed back, are according to the invention In the sheet metal holder viewing openings, additional flaps are arranged, which when going down of the engagement linkage cover the viewing openings.
Die Zeichnung gibt die schematische Darstellung einer Ausführungsform wieder.The drawing gives the schematic representation of an embodiment again.
Die vom Maschineneinrückhebel kommende Stange a der Maschine ist durch das Gestänge b, c, d mit' einer Drehachse e verbunden, auf der Klappen f sitzen, die in die Sichtöffnungen g i des Blechhalters g hineinragen, so nämlich, daß sie in der Ruhelage der Maschine auf dem unteren Rande der Sichtöffnungen liegen, während sie beim Einrükken der Maschine (Niederbewegen der Stange a) hochgeschwenkt werden (punktierte Stellung).The rod a of the machine coming from the machine engagement lever is connected by the linkage b, c, d to an axis of rotation e, on which flaps f sit, which protrude into the viewing openings gi of the sheet metal holder g, so that they are in the rest position of the machine lie on the lower edge of the viewing openings, while they are swiveled up when the machine is engaged (lowering of the rod a) (dotted position).
Auf der Drehachsee sitzt ferner ein Kokken h, der einen drehbaren, mit Führungsrolle h versehenen Hebel i gegen die Wirkung einer Feder n ausschwenken kann. An diesem Hebel ist eine Schutzleiste »z befestigt, die beim Niedergehen des Einrückgestänges nach dem Arbeiter zu ausschwenkt und den Raum zwischen Blechhalter und Scherentisch p abdeckt.On the Drehachsee there is also a coke h which can swivel out a rotatable lever i provided with a guide roller h against the action of a spring n. A protective strip z is attached to this lever, which swings out towards the worker when the engaging rod goes down and covers the space between the sheet metal holder and the scissor table p.
