Description

Schnellaufende kurzhubige Blechschere mit plattenförmigem Gestell zu scherende Blech vorgesehen. der von einer längs des inneren Randes der Arine angeordneten 5 begrenzt wird.High-speed, short-stroke tin snips with a plate-shaped frame sheet to be sheared provided. which is delimited by a 5 arranged along the inner edge of the arine.

Der Antrieb besteht aus einem seitlich an dein olleren Art" 3 befestigten Elektromotor h, welcher dem oberen der beiden Schneidwerkzeuge 7, 8 eitle schnelle auf- und abwärts gehende Bewegung erteilt. Das ollere Werkzeug 7 ist für diesen Zweck an einem in dein oberen :drin 3 in senkrechter Richtung geführten Schlitten 9 1zefestigt, der mittels eines aus zwei Armen io, i i bestehenden Kniehebelmechanisnius mit einer all der -Motorwelle 12 exzentrisch gelagerten Pleuelstange 13 verbunden ist. Die Pleuelstange 13. welche zusammen mit der EZzenterscheibe 14 durch ein Gegengewicht 1,5 ausbalanciert ist, hat ein gegabeltes linde und ist nlit den beiden Armen durch einen Zapfen verbunden. der den Aren to finit (lein gegabelten Ende des Armes ii verbindet. Der Arm io ist an seinem unteren lade durch einen Zapfen finit dein Schritteil 9 verbunden, -\välirencl der Aren ii all seinem olleren Ende in eineng in (lern Gestell eingeschraubten Bolzen unter Verinittlung einer Hälse gelagert ist. die durch einen mit einem Handgriff 22 verseheilen Hebel 23 in zwei verschiedene Lagen 7u111 Heben oder Senken des Schlittens 9 eingestellt «-erden kann. Bei der gezeigten Lage des Hebels 23 nimmt der Mechanismus seine unterste Lage ein, wobei der Hellet 23 mittels einer Pill11e ?4. gegen eine Anschlagfläche der Deckplatte 25 anliegt. Bei "Umstellung des Hebels 23 uni igo° nach links (hir. 3) legt sich die Pinne 24: gegen eine entsprechende Anschlagflüche 26 an .der anderen Seite der Deckplatte 25. Dadurch wird auch das obere Schneidwerkzeug 7 aus seiner in Fig. 3 gezeigten Arbeitslage .gehoben. so daß das Blech, welches geschnitten werden soll, zwischen die beiden Schueidwerkzeuge 7 und 8 ein:gefi.ilirt werden kann. Die Deckplatte 25 ist all dein Gestell teils mittels einer auf dem La-erbolzen des Arins i i aufgeschraubten Mutter 2z8 und teils mittels einer Mutter 2c9 befesti-t. die auf dein äußeren Ende eines in dem Gestell eingescliratiliteil r#iilirun"sllolzeils angebracht ist.The drive consists of an electric motor h attached to the side of the older type "3, which gives the upper of the two cutting tools 7, 8 vain rapid upward and downward movement. The older tool 7 is for this purpose on one of the upper ones 3, which is guided in the vertical direction and which is connected by means of a toggle mechanism consisting of two arms io, ii to a connecting rod 13 eccentrically mounted on all of the motor shaft 12. The connecting rod 13, which together with the e center disk 14 is connected by a counterweight 1.5 is balanced, has a forked linden tree and is connected to the two arms by a pin, which connects the aren to finite (the forked end of the arm ii. The arm io is connected to its lower drawer by a pin finite step part 9, - \ valirencl the arene ii is mounted at all its outer end in a bolt screwed into the frame under the mediation of a neck h a lever 23 equipped with a handle 22 can be set in two different positions 7u111 raising or lowering the carriage 9. In the position of the lever 23 shown, the mechanism assumes its lowest position, the Hellet 23 by means of a pill11e? 4. against a stop surface of the cover plate 25. When the lever 23 is shifted uni igo ° to the left (here 3), the tiller 24 rests against a corresponding stop flange 26 on the other side of the cover plate 25. This also removes the upper cutting tool 7 from its position shown in FIG The working position is raised so that the sheet metal to be cut can be filled between the two shoe tools 7 and 8. The cover plate 25 is all your frame partly by means of a nut 2z8 screwed onto the bearing bolt of the Arin II and partly fastened by means of a nut 2c9, which is attached to the outer end of a bracket part that is clamped into the frame.

Die Sclineidwvrl;zeu,e7 und S haben die Fonn von Meißeln, deren Schäfte einen rechtrakigen oder quadratischen Querschnitt Haben. Das ollere Werkzeug 7 ist in dein als jVerkzeughalter 35 ausgebildeten unteren 'eil des Schlittens q befestigt. Das untere Sclinci(l«-erl;zeu-, 8 ist in (lern unteren Arm 4 unter 1Termttlung einer Haltevorrichtung lest angebracht. Der 'Motor kann eine UmcIrelitings7alil voll iooo bis 2ooo Unidrehunren in der 'Minute oder mehr haben.The Sclineidwvrl; zeu, e7 and S have the shape of chisels, their shafts have a rectangular or square cross-section. The older tool 7 is attached to the lower part of the slide q, which is designed as a tool holder 35. The lower sclinci (l «-erl; zeu-, 8 is in (learn lower arm 4 under 1 determination of a Holding device reads attached. The 'engine can do a UmcIrelitings7alil fully iooo have up to 2,000 university rotations per minute or more.
