Description

Die Erfindung richtet sich auf ein Spann- und Verformungswerkzeug mit in Art eines Schraubstockes der im Oberbegriff des Anspruches 1 angegebenen Gattung, vgl. DE-C-32 11 521.The invention relates to a clamping and deformation tool with in the manner of a vice of the type specified in the preamble of claim 1, cf. DE-C-32 11 521.

Spannwerkzeuge mit Spindeltrieb, die von Hand betätigbar sind, sogenannte Schraubstöcke, sind in unterschiedlichen Gestaltungen bekannt. Dabei ist es auch bekannt, die Spannbacken je nach Anwendungszweck unterschiedlich und auswechselbar zu gestalten, wozu hier lediglich als Beispiel auf die DE-C-34 30 814 oder DE-A-41 37 927 hingewiesen sei. Das Problem, Spannbacken auswechselbar zu gestalten, ist vergleichsweise alt, so daß auch sehr alte Lösungen bekannt sind, beispielsweise DE-C-28 49 92 oder DE-C-34 14 34.Clamping tools with spindle drive, which can be operated by hand, so-called vices, are known in different designs. It is also known to design the jaws differently and interchangeably depending on the intended use, for which purpose DE-C-34 30 814 or DE-A-41 37 927 is only mentioned here as an example. The problem of designing interchangeable jaws is comparatively old, so that very old solutions are also known, for example DE-C-28 49 92 or DE-C-34 14 34.

Bei Verformungswerkzeugen ist es notwendig, hohe Verformungskräfte aufzuwenden, die häufig von einem über einen Spindeltrieb von Hand zu betätigenden Schraubstock nicht aufgebracht werden können, so daß es bekannt ist, auch um sehr hohe Spannkräfte aufzubringen, mechanische Übersetzungsgetriebe als Antrieb vorzusehen, wie z.B. in der FR-C-1 054 956 oder DE-A-2 058 806 beschrieben.In the case of deformation tools, it is necessary to apply high deformation forces, which frequently cannot be applied by a vice that can be operated manually via a spindle drive, so that it is known to provide mechanical transmission gears as a drive, even in order to apply very high clamping forces, e.g. in FR-C-1 054 956 or DE-A-2 058 806.

Es besteht oft der Bedarf, auf Werkbänken für die Durchführung unterschiedlichster Bearbeitungsaufgaben, wie z.B. Biegen verschiedener Formen, Nieten, Prägen, Sicken, Stanzen, Schneiden von Flach-, Rund- und Profilmaterial sowie von Rohr aus Stahl, Buntmetallen, Kunststoffen, textilen oder ähnlichen Werkstoffen, ein Werkzeug zu benutzen, mit dem alle diese Aufgaben durchgeführt werden können.There is often a need for workbenches to perform a wide variety of machining tasks, such as bending various forms, rivets, embossing, beads, punching, cutting of flat, round and profile material as well as of steel, non-ferrous metals, plastics, textiles or similar materials to use a tool with which all these tasks can be carried out.

Dazu ist es notwendig, diesen Werkstock mit einer Kraftbetätigung auszurüsten, Hilfsmittel, wie verstellbare Anschläge und Lineale zu integrieren und in diesem die den Arbeitsaufgaben entsprechenden Werkzeuge schnellwechselbar anzuordnen.To do this, it is necessary to equip this workbench with a power actuator, to integrate aids such as adjustable stops and rulers, and to quickly arrange the tools corresponding to the work tasks.

Werkzeuge für diese Arbeitsaufgaben bestehen üblicherweise aus zwei Teilen, sie können in Form von Platten als Schneid- oder Prägewerkezeuge u.ä. einerseits und als Gegenstück oder Amboß dazu andererseits ausgebildet sein. Diese Platten müssen positionsgenau zueinander ausgerichtet sein.Tools for these work tasks usually consist of two parts, they can be in the form of plates as cutting or embossing tools and the like. on the one hand and as a counterpart or anvil on the other hand. These plates must be exactly aligned with each other.

Bei bekannten Lösungen, zu denen auch die eingangs genannten DE-C-32 11 521 des Anmelders gehört oder die US-1 799 526 und US-2 489 731 werden Lösungen nur für Teilbereiche angeboten, d.h. entweder ist ein Anpassen der Spannbacken an unterschiedliche Aufgabenstellungen möglich oder die Aufbringung höherer Klemmkräfte. So zeigt die DE-C-32 11 521 zur Erhöhung der Spannkraft einen über ein Pedal zustellbaren Spannbacken. Eine Möglichkeit, über Schrauben und Führungsstifte Spannbacken auswechselbar an einer solchen Vorrichtung vorzusehen, zeigt auch die US-4 519 592, allerdings muß dort jeweils wenigstens eine Schraube über mehrere Gewindegänge gedreht werden, um den jeweiligen Spannbacken zum Auswechseln zu lösen bzw. umgekehrt in der Arbeitsposition zu fixieren.In known solutions, which also include the applicant's DE-C-32 11 521 mentioned at the outset or US Pat. Nos. 1,799,526 and 2,489,731, solutions are only offered for partial areas, ie either the jaws are adapted to different tasks possible or the application of higher clamping forces. For example, DE-C-32 11 521 shows a clamping jaw that can be adjusted via a pedal to increase the clamping force. One way to use jaws with screws and guide pins US Pat. No. 4,519,592 also shows interchangeably to be provided on such a device, but at least one screw must be turned over a plurality of thread turns in order to loosen the respective clamping jaws for replacement or vice versa to fix them in the working position.

Demgegenüber ist Aufgabe der Erfindung, ein Multi-Funktions-Werkzeug zu schaffen, das jeweils schnell den unterschiedlichen Einsatzzwecken anpaßbar ist und mit dem bei Bedarf nicht nur hohe Spann-, sondern auch Verformungskräfte aufbringbar sind.In contrast, the object of the invention is to create a multi-function tool which can be quickly adapted to the different purposes and with which not only high clamping forces but also deformation forces can be applied if necessary.

Mit einem Spann- und Verformungswerkzeug der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Durch die Führung der Werkzeugbacken im Grundkörper bzw. Schlitten wird eine exakte Positionierung möglich, was bei präzisen Arbeiten notwendig ist. Durch die Möglichkeit einer Schnellwechseleinrichtung der Werkzeugbacken ist eine einfache Handhabung und schnelle Anpassung an unterschiedliche Arbeiten möglich.With a clamping and deformation tool of the type described in the introduction, this object is achieved according to the invention by the characterizing features of claim 1. By guiding the tool jaws in the base body or slide, exact positioning is possible, which is necessary for precise work. The possibility of a quick-change device for the tool jaws enables easy handling and quick adaptation to different jobs.

Die L-förmige Ausgestaltung der Werkzeugbacken mit entsprechenden Führungen in den sonstigen Werkzeugelementen macht eine genaue Ausrichtung der Werkzeugbacken möglich. Die Ausgestaltung der Schnellwechseleinrichtung mit einem Zugkopf und einem federbeaufschlagten Zugstift macht es möglich, hier je nach Vorspannung eine Handbetätigung mittels Druckknopf vorzusehen, wobei z.B. durch eine Innenbohrung im Druckknopf und die dadurch gewährleistete Möglichkeit, die Vorspannmutter zu betätigen, eine sehr kompakte Bauweise möglich ist.The L-shaped design of the tool jaws with corresponding guides in the other tool elements enables precise alignment of the tool jaws. The design of the quick-change device with a pulling head and a spring-loaded traction pin makes it possible, depending on the preload, to provide a manual actuation by means of a push button, whereby a very compact design is possible, for example, due to an inner bore in the push button and the possibility of actuating the preload nut guaranteed thereby.

Weitere erfindungsgemäße Ausgestaltungen ergeben sich aus den Unteransprüchen.Further refinements according to the invention result from the subclaims.

Neben anderen Möglichkeiten, eine Umformkraft aufzubringen, bietet sich ein fußbetätigtes Gestänge an, wobei das Verlegen der Angriffsebene des Betätigungsgestänges in eine Ebene vor der ortsfesten Werkzeugbacke wiederum zu einer sehr kompakten und einfachen Bauweise führt.In addition to other possibilities of applying a forming force, a foot-operated linkage is available, whereby the laying of the attack level of the actuation linkage in a level in front of the stationary tool jaw in turn leads to a very compact and simple construction.

Das allgemein mit 1 bezeichnete Werkzeug ist mit dem Grundkörper 2, in dem ein Schlitten 3 in Führungsschienen 4 bewegbar ist, an einer nicht näher bezeichneten strichpunktiert dargestellten Werkbank befestigt.The tool, generally designated 1, is fastened to the base body 2, in which a slide 3 can be moved in guide rails 4, on a workbench, not shown in dash-dot lines.

Die Bewegung des Schlittens 3 wird von einem Zustellelement bewirkt, welches im dargestellten Beispiel aus einer im Grundkörper 2 gelagerten Spindelhülse 5 und einer im Schlitten festgelegten Spindel 6 besteht, die in die Spindelhülse 5 eingreift. Der vordere Teil der Spindelhülse 5 ist abgesetzt und im Grundkörper in einer abgesetzten Bohrung axial verschiebbar gelagert. Auf der Spindelhülse 5 ist drehbar eine Buchse 7 angeordnet, die auf der einen Seite an einem Bund der Spindelhülse 5 ansitzt und andererseits mit einem Federring 8 in axialer Richtung fixiert wird.The movement of the carriage 3 is brought about by an infeed element which, in the example shown, consists of a spindle sleeve 5 mounted in the base body 2 and a spindle 6 fixed in the carriage, which engages in the spindle sleeve 5. The front part of the spindle sleeve 5 is stepped and axially displaceably mounted in a stepped bore in the base body. A bushing 7 is rotatably arranged on the spindle sleeve 5, which is seated on one side on a collar of the spindle sleeve 5 and on the other hand is fixed in the axial direction with a spring ring 8.

In eine Ringnut 9 der Buchse 7 greift mit einem Nocken 10 ein im Grundkörper 2 um einen Bolzen 11 schwenkbares Gestänge 12 ein. Das Gestänge 12 ist höhenverstellbar und mittels des Pedales 12a zu betätigen.In a ring groove 9 of the bushing 7 engages with a cam 10 in the base body 2 about a pin 11 pivotable linkage 12. The linkage 12 is adjustable in height and can be actuated by means of the pedal 12a.

Im Bereich des Abstandes zwischen dem Absatz der Spannhülse 5 und der diesem zugewandten Planseite der Buchse 7 ist mit Betätigung des Gestänges 12 die Buchse 7 mit Spindelhülse 5 sowie Spindel 6 und damit der Schlitten 3 längs bewegbar. Der Schlitten 3 kann aber auch durch Drehen der Spindelhülse 5 auf der Spindel 6 bewegt werden. Dabei stützt sich die Buchse 7 mit der Spindelhülse 5 am Grundkörper 2 ab. Zur Ausübung der Drehbewegung ist im vordersten Teil der Spindelhülse 5 ein Handhebel bzw. Knebel 13 angeordnet.In the area of the distance between the shoulder of the clamping sleeve 5 and the plan side of the bushing 7 facing it, the bushing 7 with spindle sleeve 5 and spindle 6 and thus the slide 3 can be moved longitudinally by actuating the linkage 12. The carriage 3 can also be moved by rotating the spindle sleeve 5 on the spindle 6. The bushing 7 is supported on the base body 2 with the spindle sleeve 5. A hand lever or toggle 13 is arranged in the foremost part of the spindle sleeve 5 in order to carry out the rotary movement.

Im oberen Bereich des Grundkörpers 2 und des Schlittens 3 sind Werkzeugbacken 14 auswechselbar befestigt. Die Werkzeugbacken 14 sind jeweils an der dem Grundkörper 2 bzw. Schlitten 3 zugewandten Seite L-förmig ausgebildet und greifen formschlüssig in entsprechende Ausnehmungen 22 des Grundkörpers 2 bzw. Schlittens 3 ein. Gegen seitliche Verschiebung sind die Werkzeugbacken 14 mit jeweils im Grundkörper 2 und im Schlitten 3 festen Stiften 15, die in Bohrungen der Werkzeugbacken 14 eingreifen, positioniert.In the upper area of the base body 2 and the slide 3, tool jaws 14 are fastened in an exchangeable manner. The tool jaws 14 are each L-shaped on the side facing the base body 2 or slide 3 and engage positively in corresponding recesses 22 of the base body 2 or slide 3. The tool jaws 14, each with fixed pins 15 in the base body 2 and in the slide 3, which engage in bores in the tool jaws 14, are positioned against lateral displacement.

In einer abgesetzten Bohrung 23, jeweils im Grundkörper 2 und Schlitten 3, ist eine Schnellwechseleinrichtung "S", bestehend aus einem Zugkopf 16 mit einem Zugstift 16a, einer Mutter 17, einem Druckknopf 18, einer Feder 19, einem Sprengring 20 und einem Stift 21, angeordnet.A quick-change device "S", consisting of a pulling head 16 with a pulling pin 16a, a nut 17, a push button 18, a spring 19, a snap ring 20 and a pin 21, is in a stepped bore 23, in each case in the base body 2 and slide 3 , arranged.

Der Zugstift 16a besteht aus einem Gewindeteil und einem Kopf 16, wobei der Kopf 16 abgeflacht ist und mit seiner Abflachung auf einer Ausnehmung 22 der Werkzeugplattenaufnahme des Grundkörpers 2 bzw. des Schlittens 3 aufliegt.The traction pin 16a consists of a threaded part and a head 16, the head 16 being flattened and resting with its flattening on a recess 22 in the tool plate receptacle of the base body 2 or the slide 3.

Die Mutter 17 ist in der abgesetzten Bohrung 23 auf dem Gewindeteil des Zugstiftes 16a drehbar. Zwischen einem ringförmigen Ansatz der Mutter 17 und der Ringfläche der abgesetzten Bohrung 23 ist die Feder 19 angeordnet. Durch die Feder 19 wird bei Eingriff des Kopfes 16 des Zugstiftes 16a in die Nut der jeweiligen Werkzeugbacke 14 diese in die formschlüssige L-förmige Aufnahme gezogen.The nut 17 is rotatable in the stepped bore 23 on the threaded part of the pull pin 16a. The spring 19 is arranged between an annular extension of the nut 17 and the annular surface of the stepped bore 23. When the head 16 of the tension pin 16a engages in the groove of the respective tool jaw 14, the spring 19 pulls it into the form-fitting L-shaped receptacle.

Auf einem Ansatz der Mutter 17 und einer Bohrung in dem Druckknopf 18 ist über einen in Ringnuten angeordneter Sprengring 20 eine drehbare Verbindung hergestellt. Der Druckknopf 18 ist mit einem Stift 21, der in ein Langloch des Druckknopfes 18 eingreift, gegen Verdrehen gesichert.On a shoulder of the nut 17 and a bore in the push button 18, a rotatable connection is made via a snap ring 20 arranged in ring grooves. The push button 18 is secured against rotation by a pin 21 which engages in an elongated hole in the push button 18.

Durch eine Längsbohrung im Druckknopf 18 ist ein Werkzeug, wie Schraubendreher oder Innensechskantschlüssel mit einem Schlitz oder Innensechskant der Mutter 17 in Verbindung zu bringen. Die Mutter 17 ist damit bei Bedarf gegen den Bohrungsansatz fest mit dem Zugstift 16 verschraubbar, wodurch über die Verbindung Haken des Zugstiftes 16 und Nut der Werkzeugbacke 14 eine feste Verbindung der jeweiligen Werkzeugbacke 14 mit dem Grundkörper 2 oder dem Schlitten 3 hergestellt werden kann. Beim Lösen dieser Verbindung ist jeweils die Mutter 17 zu lösen und dann über den Druckknopf 18 längs zu bewegen, wodurch die Werkzeugbacke 14 freigegeben wird.A longitudinal hole in the push button 18 is used to connect a tool, such as a screwdriver or Allen key, to a slot or hexagon socket of the nut 17. The nut 17 can thus, if necessary, be screwed firmly against the hole attachment to the pull pin 16, so that the hook of the pull pin 16 and the groove of the tool jaw 14 connect the respective tool jaw firmly 14 can be produced with the base body 2 or the slide 3. When loosening this connection, the nut 17 is to be loosened and then moved longitudinally via the push button 18, whereby the tool jaw 14 is released.
