Description

Die Erfindung betrifft eine manuelle Bearbeitungsvorrichtung zum Abkanten von Metallflachblechen für den mobilen Baustelleneinsatz.The invention relates to a manual processing device for bending flat metal sheets for mobile construction site use.

Schwenkbiegen ist ein Fertigungsverfahren. Es zählt in der Hauptgruppe des Umformens zur Gruppe Biegeumformen, wo es gemeinsam mit dem Walzbiegen, Rundbiegen und Umlaufbiegen der Untergruppe des Biegeformens mit drehendem Werkzeug zugeordnet ist. Für das Schwenkbiegen werden schwenkbare Biegewangen als Werkzeug eingesetzt. Das Werkstück ist dabei zwischen separaten Oberwangen und Unterwangen eingespannt und wird gebogen. Durch Schwenkbiegen kann man ähnliche Profile herstellen wie z. B. durch das Gesenkbiegen. Dort führt das Werkzeug jedoch eine geradlinige Bewegung aus. Das Verfahren lässt sich auf einer speziellen Schwenkbiegemaschine ausführen oder in vollautomatischen Biegezentren umsetzen. Es ist allerdings wünschenswert, dass Metallflachbleche ebenso auf der Baustelle (durch einen Biegevorgang) abgekannten werden können, und dass zu diesem Zweck entsprechende Maschinen oder Werkzeuge auf der Baustelle vorhanden sind. Oft gestaltet sich dabei die Detailausbildung schwierig, da geeignete Maschinen (z. B. Schwenkbiegemaschinen) oder Spezialwerkzeuge nicht baustellenkompatibel oder schlichtweg nicht vorhanden sind.Panel bending is a manufacturing process. In the main group of forming, it belongs to the group of bending forming, where it is assigned to the sub-group of bending with rotating tools together with roll bending, round bending and rotary bending. Swivel bending beams are used as tools for swivel bending. The workpiece is clamped between separate upper beams and lower beams and is bent. Similar profiles can be produced by swivel bending, e.g. B. by die bending. There, however, the tool executes a linear movement. The process can be carried out on a special swivel bending machine or implemented in fully automatic bending centers. However, it is desirable that flat metal sheets can also be edged (by a bending process) on site and that appropriate machines or tools are available on site for this purpose. The detailed design is often difficult because suitable machines (e.g. folding machines) or special tools are not compatible with the construction site or are simply not available.

Eine mögliche auf einer Baustelle einsetzbare Vorrichtung stellt dabei die in der DE 20 2008 013 608 U1 beschriebene Vorrichtung dar. Diese weist einen Tisch auf, an welchem unter anderem eine Abkantvorrichtung aus mehreren zueinander beweglichen Wangen angeordnet ist, wobei nach Einlegen eines Bleches eine der Wange in einer Längsachse um die andere Wange gedreht wird und somit ein dazwischen liegendes Blech gebogen und abgekantet werden kann. Eine solche Vorrichtung weist den Nachteil auf, dass die Dimension der Vorrichtung relativ groß ist, und dass sie nicht ohne Weiteres an den konkreten Einsatzort wie z. B. auf dem Gerüst, Steildach mitgenommen werden kann.A possible device that can be used on a construction site is the one in the DE 20 2008 013 608 U1 device described. This has a table on which, among other things, a folding device consisting of several mutually movable cheeks is arranged, wherein after inserting a metal sheet, one of the cheeks is rotated about the other cheek in a longitudinal axis and thus a metal sheet lying in between can be bent and folded. Such a device has the disadvantage that the dimensions of the device are relatively large, and that they cannot be readily adapted to the specific place of use, e.g. B. on the scaffolding, pitched roof can be taken.

Eine rechtwinklige L-förmige mobile Vorrichtung zum Biegen eines Bleches ist aus der US 5836198 bekannt, in der das Blech in eine Tasche der Vorrichtung einschiebbar ist, wobei die Tasche entlang des langen Schenkels und in der Ebene der rechtwinkligen L-förmigen Vorrichtung angeordnet ist, und aufgrund eines Angriffs an den kurzen Schenkel das Blech gebogen werden kann.A right-angled L-shaped mobile sheet metal bending device is known from US Pat US5836198 known in which the sheet is insertable into a pocket of the device, the pocket being located along the long leg and in the plane of the right-angled L-shaped device, and by attacking the short leg the sheet can be bent.

Aufgabe der Erfindung ist es demnach, eine Vorrichtung anzugeben, mit der eine Bearbeitung, insbesondere ein Biegen und Abkanten, eines Metallflachbleches einfach und ohne aufwendigen Werkzeugeinsatz, vor Ort auf einer Baustelle, ausführbar ist. Mit Vorteil soll dabei lediglich ein Werkzeug zum weiteren Bearbeiten, insbesondere zum Anreißen und/oder Markieren von Blechen von erforderlich sein.The object of the invention is therefore to specify a device with which processing, in particular bending and edging, of a flat metal sheet can be carried out easily and without the use of complex tools, on site at a construction site. Advantageously, only one tool should be required for further processing, in particular for scribing and/or marking metal sheets.

Diese Aufgabe wird durch eine Bearbeitungsvorrichtung zur mobilen Bearbeitung von Metallflachblechen nach Anspruch 1 sowie durch ein in Anspruch 11 bezeichnetes Verfahren zur mobilen Bearbeitung von Metallflachblechen mittels einer Bearbeitungsvorrichtung gelöst. Vorteilhafte Weiterbildungen der Bearbeitungsvorrichtung sind in den Ansprüchen 2 bis 10 angegeben.This object is achieved by a processing device for the mobile processing of flat metal sheets according to claim 1 and by a method, identified in claim 11, for the mobile processing of flat metal sheets by means of a processing device. Claims 2 to 10 specify advantageous developments of the processing device.

Die Bearbeitungsvorrichtung zur mobilen Bearbeitung von Metallflachblechen weist mindestens eine Abkantvorrichtung auf, wobei die mindestens eine Abkantvorrichtung zum manuellen Abkanten eines Metallflachblechs eingerichtet ist. Dabei ist die Bearbeitungsvorrichtung einteilig geformt und besteht aus einem biegesteifen Metallteil. Zudem weist die Abkantvorrichtung eine zu einer Längserstreckung einer Seite und/oder Kante der Bearbeitungsvorrichtung parallel verlaufende, in mindestens eine Richtung offene Tasche auf, wobei die Tasche eingerichtet ist, das Metallflachblech aufzunehmen. Die Tasche weist somit eine Öffnung auf, wobei die Öffnung der Tasche in der Ebene einer Fläche liegt, welche durch wenigstens zwei Längsseiten der Bearbeitungsvorrichtung aufgespannt ist, und insbesondere an eine Kante und/oder einer Seite der Bearbeitungsvorrichtung angrenzt. Die Tasche ist dabei durch zwei zumindest teilweise durchgehende und zueinander parallele Flächen des einteiligen und biegesteifen Metallteils begrenzt, wobei die zwei Flächen über einen Verbindungssteg miteinander verbunden sind. Dabei liegt eine erste Fläche der zwei Flächen an der Kante und/oder Seite der Bearbeitungsvorrichtung an und steht senkrecht zu der durch die wenigstens zwei Längsseiten der Bearbeitungsvorrichtung definierten Fläche. Dabei sind die beiden die Tasche begrenzenden und zueinander parallel liegenden Flächen um das Maß einer Breite der Öffnung der Tasche voneinander beabstandet.The processing device for the mobile processing of flat metal sheets has at least one folding device, wherein the at least one folding device is set up for folding a flat metal sheet manually. The processing device is formed in one piece and consists of a rigid metal part. In addition, the bending device has a pocket that runs parallel to a longitudinal extent of a side and/or edge of the processing device and is open in at least one direction, the pocket is set up to receive the flat metal sheet. The pocket thus has an opening, the opening of the pocket lying in the plane of a surface which is spanned by at least two longitudinal sides of the processing device and in particular adjoins an edge and/or a side of the processing device. The pocket is characterized by two at least partially continuous and mutually parallel surfaces of the one-piece and rigid metal part delimited, wherein the two surfaces are connected to each other via a connecting web. A first surface of the two surfaces lies against the edge and/or side of the processing device and is perpendicular to the surface defined by the at least two longitudinal sides of the processing device. The two surfaces delimiting the pocket and lying parallel to one another are spaced apart from one another by the amount of a width of the opening of the pocket.

Ein Vorteil einer solche Bearbeitungsvorrichtung mit mindesten einer Abkantvorrichtung, die einen Bestandteil der einteiligen Bearbeitungsvorrichtung darstellt, ist, dass die Dimension der Bearbeitungsvorrichtung an die Bedürfnisse angepasst werden kann, und dass die Bearbeitungsvorrichtung unter anderem an jeglichem Ort auf einer Baustelle Anwendung finden kann. Zudem wird durch eine solche Abkantvorrichtung eine leichte und einfache Bearbeitung, nämlich ein Biegen und somit Abkanten eines Metallflachbleches ermöglicht, die zudem an den unterschiedlichen Orten einer Baustelle Anwendung findet.An advantage of such a processing device with at least one bending device, which is part of the one-piece processing device, is that the dimensions of the processing device can be adapted to the needs, and that the processing device can be used, among other things, at any location on a construction site. In addition, such a folding device enables easy and simple processing, namely bending and thus folding of a flat metal sheet, which is also used at different locations on a construction site.

Vorteilhafterweise ist die Bearbeitungsvorrichtung in einer Aufsicht auf die Bearbeitungsvorrichtung als ein rechtwinkliges Trapez ausgebildet, wobei das Trapez insbesondere zwei rechte Winkel bildet und drei Seiten der Bearbeitungsvorrichtung, die an die zwei rechten Winkel angrenzen, in einer Aufsicht auf die Bearbeitungsvorrichtung jeweils eine Gerade darstellen. Durch eine solche trapezförmige Ausgestaltung ist eine besonders einfache und sichere Handhabung der Bearbeitungsvorrichtung möglich, womit sich insbesondere auch ein(e) präzise(r) und/oder saubere(r) Winkelanschlag, Abstandslehre mit Ausnehmung für das Anzeichnen bzw. spätere Schneiden und/oder saubere Bearbeitung des Metallflachblechs bewerkstelligen lässt.Advantageously, the processing device is designed as a right-angled trapezium in a top view of the processing device, the trapezium forming in particular two right angles and three sides of the processing device that adjoin the two right angles each represent a straight line in a top view of the processing device. Such a trapezoidal design enables particularly simple and safe handling of the processing device, which in particular also enables a precise and/or clean angle stop, distance gauge with recess for marking or later cutting and/or clean processing of the flat metal sheet can be accomplished.

Vorteilhafterweise besteht die Bearbeitungsvorrichtung aus einem Edelstahlblech. Edelstahl ist besonders resistent gegen Korrosion und somit gut für einen Einsatz auch in einem Außenbereich auf Baustellen geeignet.Advantageously, the processing device consists of a stainless steel sheet. Stainless steel is particularly resistant to corrosion and is therefore well suited for use outdoors on construction sites.

Vorteilhafterweise weist die Bearbeitungsvorrichtung eine Dicke von 1 mm bis 2 mm, insbesondere von 1,5 mm, auf. Eine solche Dicke führt zu einem noch immer gut handhabbaren Werkzeug (auch im Hinblick auf dessen Gewicht, von insbesondere ca. 500g bis 1300g), gewährleistet aber eine ausreichende Biegesteifigkeit des Materials.Advantageously, the processing device has a thickness of 1 mm to 2 mm, in particular 1.5 mm. Such a thickness leads to a tool that is still easy to handle (also with regard to its weight, of in particular approx. 500 g to 1300 g), but ensures sufficient bending stiffness of the material.

Vorteilhafterweise ist die Form, insbesondere die Außenform, insbesondere das Ausmaß und der Außenumfang, der Bearbeitungsvorrichtung mit einem Laser, insbesondere aus einem Edelstahlblech, geschnitten. Diese Methode der Herstellung ist besonders einfach und kann präzise ausgeführt werden.Advantageously, the shape, in particular the outer shape, in particular the extent and the outer circumference, of the processing device is cut with a laser, in particular from a stainless steel sheet. This method of manufacture is particularly simple and can be carried out precisely.

Vorteilhafterweise ist eine erste Seite und/oder Kante der Bearbeitungsvorrichtung in einer Aufsicht auf die Bearbeitungsvorrichtung nicht länger als 320 mm, insbesondere nicht länger als 260 mm, und eine zweite Seite und/oder Kante der Bearbeitungsvorrichtung in einer Aufsicht auf die Bearbeitungsvorrichtung nicht länger als 250 mm, insbesondere nicht länger als 215 mm, und eine dritte Seite und/oder Kante der Bearbeitungsvorrichtung in einer Aufsicht auf die Bearbeitungsvorrichtung nicht länger als 200 mm, insbesondere nicht länger als 150 mm. Mit solchen Abmessungen ist die Bearbeitungsvorrichtung noch immer gut handhabbar als handgehaltenes und einfach mitzuführendes Werkzeug.Advantageously, a first side and/or edge of the processing device is no longer than 320 mm, in particular no longer than 260 mm, in a plan view of the processing device, and a second side and/or edge of the processing device is no longer than 250 mm in a plan view of the processing device mm, in particular no longer than 215 mm, and a third side and/or edge of the processing device in a plan view of the processing device no longer than 200 mm, in particular no longer than 150 mm. With such dimensions, the processing device is still easy to handle as a hand-held tool that is easy to carry.

Vorteilhafterweise weist die Öffnung eine Öffnungsweite auf, die größer, insbesondere um höchstens 50% größer, ist als die Dicke eines abzukantenden Metallflachblechs. Die Öffnungsweite kann insbesondere höchstens 1,5 mm, mit Vorteil höchstens 1,0 mm betragen. Ein gewisses Übermaß (größere Öffnungsweite gegenüber der Materialstärke, der Dicke, des abzukantenden Metallflachblechs ist erforderlich, um einerseits das Blech in die Tasche einführen zu können, und andererseits beim Umbiegen Raum zu haben für eine Verformung. Zu groß darf die Öffnungsweite im Verhältnis zu der Dicke des Metallflachblechs allerdings auch nicht werden, da sonst ein sauberes Abkanten nicht möglich ist, das Blech, ggf. sogar aus der Tasche herausgleiten könnte.The opening advantageously has an opening width which is larger, in particular by at most 50% larger, than the thickness of a flat metal sheet to be folded. The opening width can in particular be at most 1.5 mm, advantageously at most 1.0 mm. A certain oversize (larger opening width compared to the material thickness, the thickness of the flat metal sheet to be bent is necessary in order to be able to insert the sheet into the pocket and on the other hand to have room for deformation when bending over. The opening width may be too large in relation to the However, the thickness of the flat metal sheet must not be increased either, since otherwise clean folding is not possible and the sheet metal could possibly even slide out of the pocket.

Vorteilhafterweise liegen die zwei zueinander parallelen Flächen der Tasche im rechten Winkel zu der Fläche, welche durch wenigstens zwei Längsseiten der Bearbeitungsvorrichtung aufgespannt ist. Die rechtwinkelige Lage sorgt für ein gutes Hebelmoment für das Aufbringen der zum Abkanten erforderlichen Umformkraft. Dabei kann die Erstreckung der beiden parallelen Flächen senkrecht zu der Fläche, welche durch wenigstens zwei Längsseiten der Bearbeitungsvorrichtung aufgespannt ist, insbesondere eine Länge von 10 mm bis 40 mm, insbesondere von 20 mm aufweisen. Es hat sich gezeigt, dass Kantentiefen entsprechender Maße besonders häufig benötigt werden, so dass diese mit der erfindungsgemäßen Bearbeitungsvorrichtung einfach hergestellt werden können.Advantageously, the two mutually parallel surfaces of the pocket are at right angles to the surface defined by at least two longitudinal sides of the Processing device is clamped. The perpendicular position ensures good leverage for applying the forming force required for bending. The extent of the two parallel surfaces perpendicular to the surface which is spanned by at least two longitudinal sides of the processing device can in particular have a length of 10 mm to 40 mm, in particular 20 mm. It has been shown that edge depths of corresponding dimensions are required particularly frequently, so that they can be easily produced using the processing device according to the invention.

Vorteilhafterweise weist die Bearbeitungsvorrichtung zwei Abkantvorrichtungen auf. So können z.B. unterschiedliche Maße für die Kantentiefen erreicht werden, wenn die Abkantvorrichtungen jeweils unterschiedliche Längen haben..Advantageously, the processing device has two folding devices. For example, different dimensions for the edge depths can be achieved if the bending devices each have different lengths.

Vorteilhafterweise weist die Bearbeitungsvorrichtung eine erste Abkantvorrichtung mit einer Längserstreckung der Tasche (in einer Richtung quer zu der Öffnungsweite) der ersten Abkantvorrichtung auf, die größer ist als die Längserstreckung der Tasche einer zweiten Abkantvorrichtung. Auch unterschiedliche Längserstreckungen der parallelen Flächen sind realisierbar für verschiedene Kantenbreiten, die mit dem Werkzeug hergestellt werden können Vorteilhafterweise weist die Bearbeitungsvorrichtung an einer Seite und/oder Kante der Bearbeitungsvorrichtung, an deren Längserstreckung keine Tasche der Abkantvorrichtung verläuft, eine Anreißschablone auf, wobei die Anreißschablone zumindest teilweise an der einen Seite und/oder Kante der Bearbeitungsvorrichtung angeordnet ist und entlang dieser Erstreckung mindestens eine, insbesondere drei, Anreißnase(n) und mindestens ein, insbesondere neun, Anlegepunkt(e) angeordnet sind, wobei der mindestens eine Anlegepunkt von der mindestens einen Anreißnase um ein Abstandsmaß beabstandet ist, welches Abstandsmaß 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm und/oder 50 mm betragen kann, wobei insbesondere der Wert des Abstandsmaßes angrenzend an dem mindestens einen Anlegepunkt auf der Bearbeitungsvorrichtung angezeigt, z.B. eingraviert, ist. Diese Ausgestaltung ergibt eine noch vielfältigere Einsatzmöglichkeit der Bearbeitungsvorrichtung.The processing device advantageously has a first bending device with a longitudinal extent of the pocket (in a direction transverse to the opening width) of the first bending device which is greater than the longitudinal extent of the pocket of a second bending device. Different longitudinal extensions of the parallel surfaces can also be realized for different edge widths that can be produced with the tool Advantageously, the processing device has a marking template on one side and/or edge of the processing device, along whose longitudinal extension no pocket of the folding device runs, with the marking template at least is partially arranged on one side and/or edge of the processing device and at least one, in particular three, scribing lug(s) and at least one, in particular nine, contact point(s) are arranged along this extension, the at least one contact point being separated from the at least one marking lug is spaced apart by a distance, which distance can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm and/or 50 mm, with the value of the distance being adjacent to the at least a contact point is displayed on the processing device, eg e engraved, is. This configuration results in an even more varied application of the processing device.

Vorteilhafterweise weist die Bearbeitungsvorrichtung auf ihrer Oberfläche in einer Aufsicht auf die Bearbeitungsvorrichtung mindestens eine, insbesondere schlitzförmige, Ausnehmung, insbesondere mindestens 4 Ausnehmungen, insbesondere 22 Ausnehmungen, auf, die insbesondere mithilfe eines Lasers geschnitten sein können, wobei die mindestens eine Ausnehmung eine Längserstreckung aufweist, die zu einer Seite und/oder Kante der Bearbeitungsvorrichtung einen Winkel aufweist, der insbesondere einen Winkel von 0° bis 60° beinhaltet. Im Falle mehrerer Ausnehmungen sind die Winkel, die die jeweilige Längserstreckung zu der einen Seite und/oder Kante der Bearbeitungsvorrichtung aufweist, mit Vorteil unterschiedlich. Die Längserstreckung der insbesondere schlitzförmigen Ausnehmungen können insbesondere eine Länge von 10 mm bis 30 mm, mit Vorteil von 20 mm aufweisen und insbesondere eine Breite von 1,0 mm bis 2,0, mit Vorteil 1,5 mm haben. Weiterhin kann mit Vorteil der Wert des Winkels der mindestens einen Längserstreckung zu der einen Seite und/oder Kante der Bearbeitungsvorrichtung angrenzend an die mindestens eine Ausnehmung auf dem Werkzeug dargestellt sein, z.B. eingraviert. Auch diese Gestaltung ergibt einen weiteren Nutzen der Bearbeitungsvorrichtung, nämlich als Winkelmesser.Advantageously, the processing device has on its surface, in a plan view of the processing device, at least one, in particular slot-shaped, recess, in particular at least 4 recesses, in particular 22 recesses, which can be cut in particular with the aid of a laser, the at least one recess having a longitudinal extent which has an angle to a side and/or edge of the processing device, which angle includes in particular an angle of 0° to 60°. In the case of several recesses, the angles that the respective longitudinal extension has to the one side and/or edge of the processing device are advantageously different. The longitudinal extent of the in particular slot-shaped recesses can in particular have a length of 10 mm to 30 mm, advantageously 20 mm, and in particular a width of 1.0 mm to 2.0, advantageously 1.5 mm. Furthermore, the value of the angle of the at least one longitudinal extent to the one side and/or edge of the processing device can advantageously be shown, e.g. engraved, adjacent to the at least one recess on the tool. This design also results in a further benefit of the processing device, namely as a protractor.

Gleichermaßen können die Ausnehmungen zum Aufnehmen von Deichneigungen, Gefällen, Biegeradien etc. verwendet werden. Auch kann während eines Bauvorganges eine entsprechende Neigung in ihrem Winkeln mit der Bearbeitungsvorrichtung kontrolliert werden.Equally, the recesses can be used to accommodate dyke inclinations, gradients, bending radii, etc. The angles of a corresponding inclination can also be checked with the processing device during a construction process.

Gelöst wird die Aufgabe ebenso mit einem Verfahren zum mobilen Bearbeiten von Metallflachblechen mit einer einteiligen und aus einem biegesteifen Metallteil bestehenden Bearbeitungsvorrichtung nach der vorstehenden Beschreibung, wobei das Metallflachblech mit einer an der Bearbeitungsvorrichtung angeordneten Abkantvorrichtung dadurch bearbeitet und abgekantet wird, dass das Metallflachblech in eine Öffnung einer Tasche der Abkantvorrichtung gelegt wird, und durch manuelles Bewegen der einteiligen Bearbeitungsvorrichtung in Relation zu dem Metallflachblech der in die Tasche der Abkantvorrichtung eingelegte Abschnitt des Metallflachblechs abgekantet wird.The object is also achieved with a method for mobile processing of flat metal sheets with a one-piece processing device consisting of a rigid metal part according to the above description, the flat metal sheet being processed and folded with a folding device arranged on the processing device in that the flat metal sheet is placed in an opening is placed in a pocket of the folding device, and by manually moving the one-piece processing device in relation to the flat metal sheet, the portion of the flat metal sheet placed in the pocket of the folding device is folded.

In Figur 1 ist eine Aufsicht auf die Bearbeitungsvorrichtung gezeigt. Die Bearbeitungsvorrichtung weist dabei eine allgemein trapezförmige Außenkontur auf, wobei drei aneinanderliegende Seiten 3, 6, 6' jeweils im rechten Winkel zueinander stehen. Entlang zweier sich gegenüberliegenden Längserstreckungen 3, 6' der parallelen Kanten der Bearbeitungsvorrichtung erstreckt sich jeweils eine Abkantvorrichtung 2, 2'. Zudem ist an einer weiteren, vierten Kante 9 der Bearbeitungsvorrichtung eine Anreißschablone 10 angeordnet. Diese erstreckt sich nur teilweise über die vierte Kante 9. Die Anreißschablone 10 weist mehrere Anreißnasen 11 auf, mit welchen mögliche Maße auf dem Metallflachblech markiert werden können. Dazu sind ebenso Anlegepunkte 12 an der Anreißschablone 10 angeordnet, wobei die Anlegepunkte 12 von jeweils einer Anreißnasen 11 beanstandet sind. Der jeweilige Abstand zwischen einem Anlegepunkt 12 und einer Anreißnasen 11 kann dabei unterschiedlich ausgestaltet sein. In diesem Ausführungsbeispiel sind mehrere Anreißnasen 11, insgesamt drei, mit jeweils einem oder mehreren Anlegepunkten 12, insgesamt neun, dargestellt. Dabei weisen die Anlegepunkte 12 unterschiedliche Abstände zu jeweils einer Anreißnasen 11 auf.In figure 1 a top view of the processing device is shown. The processing device has a generally trapezoidal outer contour, with three adjacent sides 3, 6, 6' each being at right angles to one another. A bending device 2, 2' extends along each of two opposite longitudinal extensions 3, 6' of the parallel edges of the processing device. In addition, a marking template 10 is arranged on a further, fourth edge 9 of the processing device. This extends only partially over the fourth edge 9. The scribing template 10 has several scribing lugs 11, with which possible dimensions can be marked on the flat metal sheet. For this purpose, contact points 12 are also arranged on the scribing template 10, with the contact points 12 being spaced apart by a scribing nose 11 in each case. The respective distance between a contact point 12 and a marking nose 11 can be configured differently. In this embodiment, several scribing lugs 11, three in all, each with one or more application points 12, nine in all, are shown. In this case, the contact points 12 have different distances to a marking nose 11 in each case.

Die Länge der Erstreckung ist dabei neben dem Anlegepunkt 12 zur Vereinfachung während der Bedienung der Bearbeitungsvorrichtung auf der Bearbeitungsvorrichtung dargestellt, z.B. eingraviert. Durch die Funktion als Anreißschablone können Werkstücke, z.B. in 5 mm Abständen von 0 bis 50 mm, markiert werden. Dazu wird die Vorderkante, der zu kantenden Seite des Metallflachbleches an den für den geplanten Abstand vorgesehenen Anlegepunkt geschoben und der Abstand mit der Anreißnase auf dem Metallflachblech markiert.The length of the extension is shown next to the contact point 12 for simplification during the operation of the processing device on the processing device, for example engraved. Workpieces can be marked, for example at 5 mm intervals from 0 to 50 mm, thanks to the function as a marking template will. To do this, the front edge of the side of the flat metal sheet to be bent is pushed to the contact point provided for the planned distance and the distance is marked on the flat metal sheet with the marking nose.

Zudem sind mehrere Ausnehmungen 13 zu erkennen, die die Oberfläche der Bearbeitungsvorrichtung durchbrechen. Diese Ausnehmungen 13 weisen jeweils eine Längserstreckung entlang einer Seite der Ausnehmung 14 auf. Sie sind allgemein rechteckförmig oder schlitzförmig gebildet. Dabei ist die Längserstreckung der jeweiligen Ausnehmungen einer Winkelrelation im Verhältnis zu einer Kante der Bearbeitungsvorrichtung, die als Referenz- oder Grundkante dient, eingerichtet oder angeordnet. In dem vorliegenden Ausführungsbeispiel der Figur 1 stellt die Grundkante die Kante bzw. Seite 6 der Bearbeitungsvorrichtung dar. Dabei sind Ausnehmungen 13 mit einem Winkel zu der Kante 6 von 0° bis 60° mit unterschiedlichen Winkelwerten und beabstandet zueinander angeordnet.In addition, several recesses 13 can be seen, which break through the surface of the processing device. These recesses 13 each have a longitudinal extent along one side of the recess 14 . They are generally rectangular or slit-shaped. The longitudinal extent of the respective recesses is set up or arranged in an angular relationship in relation to an edge of the processing device, which serves as a reference or base edge. In the present embodiment of the figure 1 the base edge represents the edge or side 6 of the processing device. In this case, recesses 13 are arranged at an angle to the edge 6 of 0° to 60° with different angular values and spaced apart from one another.

Die Figur 2 stellt eine Seitenansicht der Bearbeitungsvorrichtung aus Figur 1 dar, wobei eine Ansicht auf die Kante bzw. Seite 6 der Bearbeitungsvorrichtung gezeigt ist. Die Abkantvorrichtungen 2, 2' grenzt dabei an eine Seite 3 der Bearbeitungsvorrichtung an, wobei die Abkantvorrichtungen 2, 2' Teil der Bearbeitungsvorrichtung 1 sind, welche insgesamt einteilig ausgebildet ist. Die Abkantvorrichtungen 2, 2' verlaufen dabei parallel zu der Seite 3 der Bearbeitungsvorrichtung 1 und weisen jeweils eine Tasche 4 auf, die zumindest in eine Richtung offen ist. Die Öffnung 5 der jeweiligen Tasche 4 mündet dabei in eine Ebene einer Fläche, welche durch die Längsseite 6 und die Seite 6' der Bearbeitungsvorrichtung aufgespannt wird. Die jeweilige Tasche 4 wiederum wird durch zwei zueinander parallele Flächen 7, 7' begrenzt. Da die gesamte Bearbeitungsvorrichtung, also auch die Abkantvorrichtung, einteilig ausgebildet ist, sind diese beiden Flächen 7, 7' mithilfe eines Verbindungsstegs 8 miteinander verbunden.the figure 2 shows a side view of the machining device figure 1 1, showing a view of the edge or side 6 of the processing device. The folding devices 2, 2' border on one side 3 of the processing device, with the folding devices 2, 2' being part of the processing device 1, which is designed in one piece overall. The folding devices 2, 2' run parallel to the side 3 of the processing device 1 and each have a pocket 4 which is open in at least one direction. The opening 5 of the respective pocket 4 opens into a plane of a surface which is spanned by the longitudinal side 6 and the side 6' of the processing device. The respective pocket 4 in turn is delimited by two mutually parallel surfaces 7, 7'. Since the entire processing device, including the bending device, is designed in one piece, these two surfaces 7 , 7 ′ are connected to one another by means of a connecting web 8 .

In der Figur 3a ist die Bearbeitungsvorrichtung 1 mit einer Abkantvorrichtung 2 der Figur 1 bzw. 2 dargestellt, wobei ebenso ein Metallflachblech M dargestellt ist. Zum Abkanten des Metallflachblechs M wird dieses Metallflachblech M in die Tasche 4 durch die Öffnung 5 der Abkantvorrichtung 2 eingelegt wie in Figur 3b dargestellt. Bei einer manuellen Schwenk- oder Kippbewegung der Bearbeitungsvorrichtung 1 in Relation zu dem Metallflachblech M wird das Metallflachblech entsprechend abgekantet.In the Figure 3a is the processing device 1 with a bending device 2 of figure 1 and 2, respectively, with a flat metal sheet M also being shown. To bend the flat metal sheet M, this flat metal sheet M is inserted into the pocket 4 through the opening 5 of the bending device 2, as in FIG Figure 3b shown. With a manual pivoting or tilting movement of the processing device 1 in relation to the flat metal sheet M, the flat metal sheet is folded accordingly.
