Description

Die Erfindung betrifft eine universell verwendbare Handsicken/crimpzange, welche sich durch die Auswechselbarkeit der verschiedensten Gesenke und Drückwerkzeuge zur vielseitigen Kaltverformung von Blech- und U-Profilen, insbesondere von Decken- und Wandprofilen oder beispielsweise auch zum Crimpen, eignet.The invention relates to a universally applicable hand crimping pliers, which are characterized by Interchangeability of different dies and pressing tools for versatile cold forming of sheet metal and U profiles, in particular ceiling and wall profiles or for example, also suitable for crimping.

Es sind eine Vielzahl von Sickengeräten und Sickenzangen bekannt, um die verschiedensten, für spezielle Anwendungen gedachten, Quetschverbindungen, Stanzungen von Öffnungen etc. zu erreichen.A large number of beading devices and beading pliers are known in order to Intended for special applications, crimp connections, punching openings etc. to reach.

So sind zum Beispiel Stanzzangen zum Stanzen von Öffnungen, insbesondere in Kunststoffdosen (OS DE 195 05 613), bekannt oder ein Sickengerät zur Herstellung von gesickten elektrischen Verbindungen nach der AS 1144804. Mit keinem der bekannten Geräte ist es jedoch möglich, in Blech-U-Profilen entsprechende Sicken einzubringen oder das spezielle Sickengerät noch für andere Arbeitsgänge zur Kaltverformung einzusetzenFor example, punch pliers are used to punch openings, especially in plastic cans (OS DE 195 05 613), known or a beading device for the production of beaded electrical Connections according to AS 1144804. However, it is not with any of the known devices possible to insert appropriate beads in sheet metal U-profiles or the special beading device can also be used for other cold forming operations

Ferner ist ein Formungswerkzeug nach dem PCT-Dokument WO-A-84/04475 (nächstliegender Stand der Technik) bekannt, welches sich für Arbeiten, wie Biegen und Schneiden eignet, und aus Antriebsteilen, die beweglich und zentral auf einem Werkzeugkörper befestigt sind, besteht. Durch Zusatzteile, die sich jeweils in den mit dem Werkzeugteil vorhandenen Stoß- und Stützblock einbringen lassen sind die Gebrauchsmöglichkeiten des Biegewerkzeuges zwar beträchtlich vergrößert, jedoch lassen sich auch mit diesem Werkzeug keine dünnwandigen C- und U-Profile bearbeiten und keine Doppelsicken herstellen.A shaping tool according to PCT document WO-A-84/04475 (closest prior art) is also known, which is suitable for work such as bending and cutting, and from drive parts that are movable and are attached centrally to a tool body. Through additional parts that are Have each inserted into the butt and support block provided with the tool part the possible uses of the bending tool are considerably increased, however no thin-walled C and U profiles can be machined with this tool either do not produce double beads.

Die Erfindung hat sich daher die Aufgabe gestellt, eine für die verschiedensten Arbeitsgänge der Kaltverformung universell anwendbare Handsicken/crimpzange zu entwickeln, mit der dünnwandige Blech- und U-Profile, zum Beispiel entsprechend vorbereitete Decken CD- oder U-Profile, wie sie im Trockenbau üblich sind, gleich an Ort und Stelle so bearbeiten zu können, daß damit ein vertikales oder horizontales Verbiegen und somit Herstellen eines jeden gewünschten Radius möglich ist und welche sich darüber hinaus noch für andere Arbeitsgänge eignet, beispielsweise zum Crimpen.The invention has therefore set itself the task of one for a wide variety of operations to develop the cold forming universally applicable hand beads / crimping pliers with the thin-walled Sheet metal and U profiles, e.g. appropriately prepared ceilings CD or U profiles, as they are common in drywall construction, to be able to work on the spot, that with it a vertical or horizontal bending and thus manufacture of any desired Radius is possible and which is also suitable for other operations suitable, for example for crimping.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ein Grundelement als statischer Teil, beispielsweise aus U-förmigen Stahlblech besteht, und an seiner Vorderseite so abgewinkelt und verjüngt ist, daß durch die sich so ergebenden parallelen Außenseiten ein Befestigungs- und Führungsteil entstanden ist. Im oberen Teil des Befestigungs- und Führungsteiles ist eine rechtwinklige und L-förmige Gesenkaufnahme mit einem stirnseitig daran fest verbundenen Schraubbolzen als Halterung für eine Gesenkarretierung zur Aufnahme mit einem Arretierungsstift versehener Gesenke eingebracht. Im unteren Teil des Befestigungs- und Führungsteiles befindet sich eine Gleitaufnahme, in der ein aus Flachstahl bestehender, beispielsweise mit einem Kerbsickenkeil verbundenen Schaft Aufnahme findet. Dabei dient die Unterseite des L-förmig ausgebildeten Teiles der Gesenkaufnahme sowie ein Bolzen, der gleichzeitig auch als Anschlag für einen Hebel mit Griffelement genutzt wird, als Führung. Die Vorderseite eines zur Kraftübertragung gleichfalls U-förmigen Hebels ist so gestaltet, daß zwischen einem im Grundelement gelagerten Gelenkpunkt und einem Verbindungsgelenkstift als Drehpunkt ein Hebelarm entsteht, dessen Kraft über eine doppelseitige Pleuelstange mit einer Stiftschraube als Gelenkpunkt, auf den Schaft und damit beispielsweise auf den Kerbsickenkeil übertragen wird. Die Gesenkarretierung ist vorzugsweise mit einer oder mehreren Arretierungsbohrungen versehen und vorzugsweise an dem für den Schraubbolzen durchbohrten Teil, zur Verbesserung des Einrastvorganges in die Arretierungsbohrungen der auf die Gesenkaufnahme aufgeschobenen Gesenke, leicht gekröpft. Eine vom Schraubbolzen aufgenommene Spiralfeder, die sich zwischen der Gesenkarretierung und der Oberkante des Grundelementes befindet, erleichtert gleichfalls den Einrastvorgang.According to the invention the object is achieved in that a basic element as a static part, for example made of U-shaped steel sheet, and angled on its front and is tapered so that the resulting parallel outer sides of a fastening and the guide part was created. In the upper part of the fastening and guide part is one right-angled and L-shaped die receptacle with a face firmly attached to it Screw bolt as a holder for a die lock for mounting with a locking pin provided dies. In the lower part of the fastening and guiding part there is a sliding mount in which a flat steel, for example shaft connected with a notched bead wedge is accommodated. The bottom serves here of the L-shaped part of the die holder and a bolt that simultaneously also used as a stop for a lever with a grip element, as a guide. The front one for power transmission also U-shaped lever is designed so that between a hinge point in the base element and a connecting hinge pin as a fulcrum A lever arm is created, the force of which is via a double-sided connecting rod with a stud as a hinge point, on the shaft and thus, for example, on the notched bead wedge is transmitted. The die lock is preferably with one or more locking holes provided and preferably on the part pierced for the bolt, to improve the locking process into the locking holes of the dies pushed onto the die holder, slightly cranked. A spiral spring picked up by the bolt, which is located between the die lock and the upper edge of the base element is also facilitated the locking process.

Der Kerbsickenkeil ist vorzugsweise entweder fest oder lösbar mit dem Schaft verbunden, so daß jederzeit, je nach Einsatzbedingungen, eine Austauschbarkeit entweder des Kerbsickenkeiles oder bei unlösbaren Verbindungen der gesamten Einheit Schaft-Drückwerkzeug, möglich ist. Die über Durchgangsführungen auf die Gesenkaufnahme aufschiebbaren Gesenke, beispielsweise Doppelfunktionsgesenke, sind vorzugsweise so auf die Gesenkaufnahme aufschiebbar, daß die jeweilige Gesenkaussparung dem gegenüberliegenden Kerbsickenkeil entspricht. D.h., durch die entsprechende Anwendung und Kombination der jeweiligen Gesenke sind die verschiedensten Sicken, wie Rand- und Bodensicken zur Herstellung von Wand- und Deckenprofilen, einbringbar.The notched bead wedge is preferably either fixed or detachably connected to the shaft, so that at any time depending on the conditions of use, an interchangeability either of the notched bead wedge or at permanent connections of the entire shaft-pressing tool unit, is possible. The dies that can be pushed onto the die holder via passage guides, for example Double-function dies are preferably slidable onto the die holder in such a way that the respective one Die cutout corresponds to the opposite notched bead wedge. That is, through the Appropriate application and combination of the respective dies are the most varied Beads, such as edge and bottom beads for the production of wall and ceiling profiles, can be inserted.

Ein mit Arretierungsstiften versehenes Doppelfunktionsgesenk weist vorzugsweise auf der einen Seite eine Gesenkaussparung und an der gegenüberliegenden Seite einen Kerbsickenkeil auf, so daß es beim jeweiligen Drückvorgang entweder nur als Arretierung eines davor verschiebbar angeordneten Doppelfunktionsgesenkes dient oder mit der Gesenkaufnahme oder dem eigenen Kerbsickenkeil selbst als Verformwerkzeug einsetzbar ist. Ein im Bedarfsfall auf der Gesenkaufnahme verschiebbar angeordnetes Doppelfunktionsgesenk ist vorzugsweise beidseitig mit Gesenkaufnahmen versehen. Eine Seite weist jedoch zusätzlich eine Aussparung auf, so daß die Gesenkaussparung dieser Seite nach oben offen ist und so ein Freiraum für das zu bearbeitende Profil oder für die Kombination mit anderen Doppelfunktionsgesenken ermöglicht wird. Ist der Schaft statt mit einem Kerbsickenkeil mit einem Crimpkopf versehen und findet dazu ein auf der Gesenkaufnahme aufgeschobenes und mit einem L-förmig verlängerten Arbeitsteil arretiertes Crimpgesenk Verwendung, ist die Handsickenzange gleichzeitig als Crimpzange abwandelbar.A double-function die provided with locking pins preferably has one on one side Die cutout and on the opposite side a notched bead wedge so that it in the respective pressing process either only as a locking device arranged in front of it Double-function die or serves with the die holder or your own Notched bead wedge itself can be used as a shaping tool. One on the die holder if necessary slidably arranged double-function die is preferably on both sides with die mounts Mistake. However, one side has an additional recess, so that the die recess this side is open at the top and so there is free space for the profile to be processed or for combination with other double function dies. If the shaft is provided with a crimp head instead of a notched bead wedge and finds it a working part slid onto the die holder and extended with an L-shape locked crimping die use, the hand crimping pliers are also used as crimping pliers changeable.

Mit der Erfindung wird erreicht, daß mit nur einer Handsicken/crimpzange als Grundgerät durch die schnelle Austauschbarkeit und Anwendung der verschiedenartigsten Gesenke, die im Trockenbau anfallenden Anpassungen, beispielsweise der verschiedensten Deckenprofile, wie beispielsweise Rundbögen, sofort an Ort und Stelle möglich sind und ein sonst üblicher Deckenunterbau entfallen kann. Somit werden Transportwege, hoher Zeitaufwand und damit im Zusammenhang stehende Kosten eingespart.With the invention it is achieved that with only one hand beads / crimping pliers as the basic device by rapid interchangeability and application of the most diverse dies, which in the Drywall adjustments, for example the most varied ceiling profiles, such as for example, round arches, are immediately possible on the spot and an otherwise usual Ceiling substructure can be omitted. Thus, transport routes, a lot of time and thus related costs saved.

Nach Fig. 1 und 2 besteht die Handsicken/crimpzange aus einem statischen Teil, als Grundelement 1. Das aus U-förmigen Stahlblech bestehende, nach oben offen ausgebildeten Grundelement 1 ist im vorderen Teil so abgewinkelt und verjüngt sich so, daß durch die sich ergebenen Außenseiten 2 ein Befestigungs- und Führungsteil 3 entsteht. Der oberen Teil des Befestigungs- und Führungsteiles 3 dient dabei zur Befestigung einer rechtwinklig ausgebildeten Gesenkaufnahme 4 mit einem L-förmigen Verschraubungsteil, und der untere Teil des Befestigungs- und Führungsteiles 3 als Gleitaufnahme für einen aus Flachstahl bestehenden, mit einem Kerbsickenkeil 5 fest verbundenen Schaft 6. Ein an der Oberseite der Handsickenzange befindlicher Schraubbolzen 7, der fest an der Stirnseite des L-förmigen Teiles der Gesenkaufnahme 4 verschweißt ist, dient zur Aufnahme einer mit Arretierungsbohrungen 8 versehenen Gesenkarretierung 9. Um die Gesenkarretierung 9 jederzeit auswechseln zu können bzw. sie mit neuen Arretierungsbohrungen 8 versehen zu können, ist diese über eine Mutter 10 gesichert. Um beim Aufschieben der jeweiligen Gesenke ein leichtes Einrasten des mit Arretierungsstiften 11 versehenen Doppelfunktionsgesenkes 12 für Wand- und Deckenprofile und des Crimpgesenkes 13 zu ermöglichen, ist zwischen der Oberseite der Gesenkaufnahme 4 und der Unterseite der Gesenkarretierung 9 eine Spiralfeder 14 mit Unterlegscheibe 15 eingebracht.1 and 2, the hand beads / crimping pliers consist of a static part, as a basic element 1. The basic element 1 made of U-shaped steel sheet and open at the top is so angled in the front part and tapers so that through the resulting outer sides 2 a fastening and guiding part 3 is created. The upper part of the attachment and guide part 3 is used to attach a rectangular die holder 4 with an L-shaped screw part, and the lower part of the fastening and guide part 3 as a sliding mount for an existing flat steel, with a Notch bead wedge 5 firmly connected shaft 6. A located at the top of the hand bead pliers Bolt 7, which is fixed to the front of the L-shaped part of the die holder 4 is welded, serves to receive a provided with locking holes 8 Die locking device 9. To be able to replace the die locking device 9 at any time or to change it To be able to provide new locking holes 8, this is secured by a nut 10. To ensure that the respective dies are slid into place with the locking pins 11 provided double function die 12 for wall and ceiling profiles and to enable the crimping die 13 is between the top of the die holder 4 and a coil spring 14 with a washer 15 is introduced into the underside of the die lock 9.

Zur Einleitung des jeweiligen Drückvorganges wird im U-Profil des Grundelementes 1 ein gleichfalls U-förmiger Hebel 16 mit Griffelement aufgenommen.To initiate the respective pressing process, 1 is in the U-profile of the basic element likewise U-shaped lever 16 with handle element added.

Der U-förmige Hebel 16 ist in Richtung der Griffseite leicht gekröpft und seine Vorderseite ist so ausgebildet, daß zwischen dem beidseitig im Grundelement 1 gelagerten und mit Unterlegscheiben verschraubten Gelenkpunkt 17 und einem Verbindungsgelenkstift 18 als Drehpunkt, ein Hebelarm entsteht, dessen Kräfte über eine doppelseitige Pleuelstange 19 über eine Stiftschraube 20 auf den Schaft 6 und damit auf den Kerbsickenkeil 5 übertragen wird. Die beidseitig an dem Schaft 6 anliegende Pleuelstange 19 ist durch Verwendung der Stiftschraube 20 jederzeit auswechselbar.The U-shaped lever 16 is slightly cranked towards the handle side and its front is designed so that between the bearings on both sides in the base element 1 and with washers screwed hinge point 17 and a connecting hinge pin 18 as a fulcrum, a lever arm arises, the forces of which are via a double-sided connecting rod 19 via a Stud 20 is transferred to the shaft 6 and thus to the notched bead wedge 5. The Connecting rod 19 resting on both sides of the shaft 6 is by using the stud screw 20 exchangeable at any time.

Ein gleichfalls im Grundelement 1 befindlicher Bolzen 21 dient einerseits dem Hebel 16 als Anschlag und andererseits, wie der L-förmige Verschraubungsteil der Gesenkaufnahme 4, als Führungselement für den Schaft 6. A bolt 21, which is also located in the base element 1, serves on the one hand the lever 16 as Stop and on the other hand, as the L-shaped screw part of the die holder 4, as Guide element for the shaft 6.

Die notwendige Stabilität im vorderen Arbeitsbereich der Handsickenzange ergibt sich durch Verschraubung der Außenseiten 2 zusammen mit dem darin eingeschobenen L-förmigen Verschraubungsteil der Gesenkaufnahme 4 mittels Verbindungsschrauben 22.The necessary stability in the front working area of the hand crimping tool results from Screwing the outer sides 2 together with the L-shaped screw part inserted therein the die holder 4 by means of connecting screws 22.
