Definitions

  • the invention relates to a bending press for bending sheet metal, according to the preamble of claim 1.
  • Sheet metal is usually bent into a desired shape according to a bending plan by means of press brakes of this type.
  • the corresponding bending tools are provided on the upper beam and the lower beam before the bending process to be carried out.
  • different bending tools often have to be arranged one after the other on the upper beam and the lower beam.
  • the bending tools of a bending press are stored, for example, in a bending tool cabinet and are removed from it as required or stored therein when the corresponding bending tool is not in use. Tools are also required for machine maintenance and for changing the bending tools.
  • the US 2014/0225494 A1 which forms the basis for the preamble of claim 1, shows, for example, such a bending tool cabinet.
  • a disadvantage of the known solution is that the bending tools have to be transferred from the bending press to the bending tool cabinet and back to the bending press in order to equip the bending press.
  • the object of the present invention is to create a bending press for bending sheet metal, which does not have the aforementioned disadvantages and in particular makes it easier for the operator to change bending tools.

Alternatively the at least one drawer can be arranged next to the upper beam and next to the lower beam. This at least one drawer can extend in the direction of the height of the bending press, for example over the entire height of the bending press.
  • the bending tools required for processing a bending plan are available to the operator directly on the bending press and are easy for the operator to reach. The operator no longer has to transport the bending tools between the bending press and a tool cabinet to prepare the bending tools, which significantly reduces the effort required to prepare the bending tools. If the bending press is designed in such a way that the operator operates it mainly while sitting, he has to get up much less than in the case of the previously known bending presses to change the bending tools, and he also has to leave an ergonomically advantageous position less.
  • a bending press in which the at least one drawer is arranged next to the lower beam is considered to be particularly advantageous, in particular for ergonomic and structural reasons.

Tools are also required for machine maintenance and for changing the bending tools. the US 2014/0225494 A1 , which forms the basis for the preamble of claim 1, shows, for example, such a bending tool cabinet.

Nachteilig an der bekannten Lösung ist, dass zur Bestückung der Biegepresse die Biegewerkzeuge jeweils von der Biegepresse zum Biegewerkzeugschrank und zurück zu der Biegepresse überführt werden müssen.A disadvantage of the known solution is that the bending tools have to be transferred from the bending press to the bending tool cabinet and back to the bending press in order to equip the bending press.

Aus einem anderen technischen Gebiet, nämlich aus dem Gebiet der Spenglerei, wird von der Firma Thalmann Maschinenbau AG, CH-Frauenfeld, unter dem Namen THAKO eine Schwenkbiegemaschine zum Biegen von Spenglerblechen angeboten, die als Standardausrüstung eine Werkzeugschublade mit Material für den Maschinenunterhalt aufweist. Auswechselbare Biegewerkzeuge sind jedoch weiterhin separat gelagert.From another technical field, namely from the field of tinsmithing, Thalmann Maschinenbau AG, CH-Frauenfeld, offers a folding machine for bending tinplate sheets under the name THAKO, which has a tool drawer with material for machine maintenance as standard equipment. However, interchangeable bending tools are still stored separately.

Aufgabe der vorliegenden Erfindung ist es, eine Biegepresse zum Biegen von Blechen zu schaffen, welche die vorgenannten Nachteile nicht aufweist und insbesondere dem Bediener den Wechsel von Biegewerkzeugen vereinfacht.The object of the present invention is to create a bending press for bending sheet metal, which does not have the aforementioned disadvantages and in particular makes it easier for the operator to change bending tools.

Die Aufgabe wird durch die Merkmale des unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen sind in den Figuren und in den abhängigen Patentansprüchen dargelegt. Gemäss der Erfindung ist zumindest eine Schublade neben der Oberwange und/oder der Unterwange angeordnet und die zumindest eine Schublade ist zur Aufnahme von Biegewerkzeugen und/oder Teilen ausgebildet.The object is solved by the features of the independent claim. Advantageous developments are presented in the figures and in the dependent patent claims. According to the invention, at least one drawer is arranged next to the upper beam and/or the lower beam and the at least one drawer is designed to accommodate bending tools and/or parts.

Die erfindungsgemässe Biegepresse zeichnet sich durch verbesserte Ergonomie, verbesserte Prozesseffizienz und geringe Kosten aus. Die zumindest eine Schublade kann beispielsweise nur neben der Oberwange oder nur neben der Unterwange angeordnet sein. Alternativ kann die zumindest eine Schublade neben der Oberwange und neben der Unterwange angeordnet sein. Dabei kann sich diese zumindest eine Schublade in Richtung der Höhe der Biegepresse erstrecken, beispielsweise über die gesamte Höhe der Biegepresse.The bending press according to the invention is distinguished by improved ergonomics, improved process efficiency and low costs. The at least one drawer can be arranged, for example, only next to the upper beam or only next to the lower beam. Alternatively the at least one drawer can be arranged next to the upper beam and next to the lower beam. This at least one drawer can extend in the direction of the height of the bending press, for example over the entire height of the bending press.

Die für die Abarbeitung eines Biegeplans erforderlichen Biegewerkzeuge stehen dem Bediener direkt an der Biegepresse zur Verfügung und sind einfach für den Bediener erreichbar. Der Bediener muss für das Bereitstellen der Biegewerkzeuge dieselben nicht mehr zwischen der Biegepresse und einem Werkzeugschrank transportieren, womit der Kraftaufwand für das Bereitstellen der Biegewerkzeuge massgeblich reduziert wird. Ist die Biegepresse derart ausgebildet, dass der Bediener diese hauptsächlich im Sitzen bedient, muss er für das Wechseln der Biegewerkzeuge wesentlich weniger als bei den bisher bekannten Biegepressen aufstehen und dabei auch weniger eine ergonomisch vorteilhafte Position verlassen. Als besonders vorteilhaft insbesondere aus ergonomischen wie auch aus konstruktiven Gründen wird eine Biegepresse angesehen, bei der die zumindest eine Schublade neben der Unterwange angeordnet ist.The bending tools required for processing a bending plan are available to the operator directly on the bending press and are easy for the operator to reach. The operator no longer has to transport the bending tools between the bending press and a tool cabinet to prepare the bending tools, which significantly reduces the effort required to prepare the bending tools. If the bending press is designed in such a way that the operator operates it mainly while sitting, he has to get up much less than in the case of the previously known bending presses to change the bending tools, and he also has to leave an ergonomically advantageous position less. A bending press in which the at least one drawer is arranged next to the lower beam is considered to be particularly advantageous, in particular for ergonomic and structural reasons.

Auch Teile, wie z. B. Werkzeuge, manuelle oder automatische Messmittel oder Messeinrichtungen, weitere Hilfsmittel, Pflegemittel für die Biegepresse oder gar Biegeteile, stehen dem Bediener direkt an der Biegepresse zur Verfügung mit den vorgenannten Vorteilen.Also parts such as B. Tools, manual or automatic measuring equipment or measuring devices, other aids, care products for the bending press or even bent parts are available to the operator directly at the bending press with the aforementioned advantages.

Da der Aufwand für das Wechseln der Biegewerkzeuge sowie für die Zugänglichkeit von Teilen bei der erfindungsgemässen Biegepresse massgeblich reduziert ist, wirkt sich dies vorteilhaft auf die Effizienz der Biegepresse aus. Die Biegewerkzeuge und/oder die Teile sind immer direkt bei der Biegepresse verfügbar. Die erfindungsgemässe Lösung ist bei verschiebbaren beziehungsweise verfahrbaren Biegepressen ("Plug and Bend") besonders vorteilhaft, da z. B. ein separater Biegewerkzeugschrank bei einem Verschieben oder Verfahren der Biegepresse nicht auch noch nachgeführt werden muss.Since the effort for changing the bending tools and for the accessibility of parts is significantly reduced in the bending press according to the invention, this has an advantageous effect on the efficiency of the bending press. The bending tools and/or the parts are always directly available at the bending press. The solution according to the invention is particularly advantageous for displaceable or mobile bending presses ("Plug and Bend"), since e.g. B. a separate bending tool cabinet does not have to be tracked when the bending press is moved or moved.

Da das Erfordernis eines separaten Biegewerkzeugschranks entfällt, reduzieren sich die Kosten einerseits durch den Wegfall für dessen Beschaffung und andererseits durch den geringeren Platzbedarf in einer Fabrikationshalle.Since there is no need for a separate bending tool cabinet, the costs are reduced on the one hand by eliminating the need for procurement and on the other hand by the smaller space requirement in a production hall.

Vorzugsweise sind mehrere Schubladen vorgesehen, so dass eine Vielzahl von Biegewerkzeugen und/oder Teilen direkt an der Biegepresse gelagert werden können. Die mehreren Schubladen sind vorteilhaft beidseitig der Oberwange oder beidseitig der Unterwange vorgesehen, wobei aus ergonomischen wie auch aus konstruktiven Gründen eine Anordnung beidseitig der Unterwange bevorzugt ist. An einer Seite der Oberwange oder Unterwange können auch mehr als eine Schublade vorgesehen sein, was insbesondere eine einfache und damit kostengünstige Konstruktion des Schubladenmechanismus für die hier nun übereinander angeordneten Schubladen ermöglicht.Several drawers are preferably provided so that a large number of bending tools and/or parts can be stored directly on the bending press. The several drawers are advantageously provided on both sides of the upper beam or on both sides of the lower beam, with an arrangement on both sides of the lower beam being preferred for ergonomic and structural reasons. More than one drawer can also be provided on one side of the upper beam or lower beam, which in particular enables a simple and therefore cost-effective construction of the drawer mechanism for the drawers that are now arranged one above the other here.

In einer weiteren alternativen Ausführungsform sind die mehreren Schubladen neben der Oberwange und der Unterwange vorgesehen, so dass die Anzahl von an der Biegepresse gelagerten Biegewerkzeugen und/oder Teilen nochmals erhöht werden kann.In a further alternative embodiment, the multiple drawers are provided next to the upper beam and the lower beam, so that the number of bending tools and/or parts stored on the bending press can be increased again.

Weiter bevorzugt ist in zumindest einer Schublade zumindest eine Teileaufnahmeeinheit für Teile, worin die entsprechenden Teile, vorteilhaft geordnet, aufgenommen werden. Die zumindest eine Teileaufnahmeeinheit kann auch Ausschnitte mit bestimmten Winkeln relativ zueinander aufweisen, so dass beispielsweise an gebogenen Biegeteilen direkt eine Qualitätskontrolle durchgeführt werden kann.It is further preferred that at least one drawer contains at least one parts receiving unit for parts, in which the corresponding parts are received, advantageously in an orderly manner. The at least one parts receiving unit can also have cutouts with specific angles relative to one another, so that quality control can be carried out directly on bent parts, for example.

Die zumindest eine Teileaufnahmeeinheit kann einen, vorteilhaft aus der Schublade herausklappbaren und wieder einklappbaren, Getränkehalter umfassen oder gar als ein solcher ausgebildet sein. Dem Benutzer steht damit eine entsprechende Abstellmöglichkeit zur Verfügung, mit welcher die Gefahr eines unbeabsichtigten Ausschüttens beispielsweise von Kaffee, Fruchtsaft, Softdrink, Maschinenöl oder anderen in zumindest teilweise offenen Behältern befindlichen Flüssigkeiten reduziert istThe at least one parts receiving unit can comprise a drinks holder which can advantageously be folded out of the drawer and folded back in again, or can even be designed as such. The user is thus provided with an appropriate storage facility, with which the risk of unintentionally spilling coffee, fruit juice, soft drink, machine oil or other liquids in at least partially open containers is reduced

Vorzugsweise weist zumindest eine Biegewerkzeugaufnahmeeinheit und/oder zumindest eine Teileaufnahmeeinheit zumindest eine Aufnahmehalterung für zumindest ein Biegewerkzeug beziehungsweise für zumindest ein Teil auf, womit dieses Biegewerkzeug beziehungsweise dieses Teil bis zu dessen Entnahme gehalten ist und beim Öffnen und Schliessen der entsprechenden Schublade seine Position nicht ändert. Dadurch wird z. B. auch vermieden, dass ein in der Schublade befindliches Biegewerkzeug beziehungsweise ein in der Schublade befindliches Teil umkippen und unter Umständen ein Öffnen oder ein Schliessen derselben blockieren kann.At least one bending tool holder unit and/or at least one part holder unit preferably has at least one holder for at least one bending tool or for at least one part, with which this bending tool or this part is held until it is removed and does not change its position when the corresponding drawer is opened and closed. This will e.g. This also prevents, for example, a bending tool located in the drawer or a part located in the drawer from tipping over and possibly blocking the opening or closing of the same.

Bevorzugt ist die zumindest eine Biegewerkzeugaufnahmeeinheit und/oder die zumindest eine Teileaufnahmeeinheit aus der zumindest einen Schublade versetzbar, so dass die darin aufgenommenen Biegewerkzeuge beziehungsweise das darin aufgenommene Teil für den Bediener einfach zugänglich sind.Preferably, the at least one bending tool holder unit and/or the at least one part holder unit can be moved out of the at least one drawer, so that the bending tools held therein or the part held therein are easily accessible for the operator.

Vorteilhaft ist die zumindest eine Biegewerkzeugaufnahmeeinheit und/oder die zumindest eine Teileaufnahmeeinheit aus der zumindest einen Schublade herausschwenkbar, was die Zugänglichkeit des darin befindlichen Biegewerkzeugs beziehungsweise des darin befindlichen Teils zusätzlich vereinfacht.Advantageously, the at least one bending tool holder unit and/or the at least one part holder unit can be pivoted out of the at least one drawer, which Accessibility of the bending tool located therein or of the part located therein is additionally simplified.

Sind mehrere Biegewerkzeugaufnahmeeinheiten und/oder mehrere Teileaufnahmeeinheiten in einer Schublade vorgesehen, so sind für eine einfache Zugänglichkeit der darin befindlichen Biegewerkzeuge beziehungsweise der darin befindlichen Teile vorzugsweise alle diese Biegewerkzeugaufnahmeeinheiten und/oder Teileaufnahmeeinheiten aus der zumindest einen Schublade heraus versetzbar, vorteilhaft herausschwenkbar und/oder herausziehbar. Besonders vorteilhaft sind die mehreren Biegewerkzeugaufnahmeeinheiten und/oder Teileaufnahmeeinheiten parallel zueinander versetzbar.If several bending tool receiving units and/or several part receiving units are provided in a drawer, all of these bending tool receiving units and/or part receiving units can preferably be moved out of the at least one drawer, advantageously pivoted out and/or pulled out, for easy access to the bending tools located therein or the parts located therein . It is particularly advantageous for the multiple bending tool receiving units and/or part receiving units to be displaceable parallel to one another.

In einer vorteilhaften Variante ist die zumindest eine Biegewerkzeugaufnahmeeinheit und/oder die zumindest eine Teileaufnahmeeinheit über eine Anordnung aus der Schublade versetzbar, welche das Gewicht der Biegewerkzeugaufnahmeeinheit und der Biegewerkzeuge und/oder der Teileaufnahmeeinheit und der Teile aufnimmt. Beispielsweise kann die zumindest eine Biegewerkzeugaufnahmeeinheit und/oder die zumindest eine Teileaufnahmeeinheit auch ähnlich den Schubladen über Führungsschienen auf einem entsprechend ausgebildeten Schubladenmechanismus geführt sein und vorteilhaft ebenfalls mit einer Auszugssperre versehen sein.In an advantageous variant, the at least one bending tool holder unit and/or the at least one parts holder unit can be moved out of the drawer via an arrangement that absorbs the weight of the bending tool holder unit and the bending tools and/or the parts holder unit and the parts. For example, the at least one bending tool receiving unit and/or the at least one part receiving unit can also be guided similar to the drawers via guide rails on a correspondingly designed drawer mechanism and advantageously also be provided with a pull-out lock.

Vorteilhaft ist die zumindest eine Biegewerkzeugaufnahmeeinheit und/oder die zumindest eine Teileaufnahmeeinheit bis auf die Höhe der Biegelinie der Biegepresse versetzbar und/oder verschwenkbar.Advantageously, the at least one bending tool holder unit and/or the at least one part holder unit can be displaced and/or pivoted up to the level of the bending line of the bending press.

Bei einer Ausführung, bei der die zumindest eine Biegewerkzeugaufnahmeeinheit auf die Höhe der Biegelinie der Biegepresse versetzbar und/oder verschwenkbar ist, wird dadurch beispielsweise die Überführung eines Biegewerkzeugs von der Oberwange oder der Unterwange in die Biegewerkzeugaufnahmeeinheit beziehungsweise umgekehrt für den Bediener der Biegepresse wesentlich vereinfacht.In one embodiment, in which the at least one bending tool holder unit can be moved and/or pivoted to the level of the bending line of the bending press, this significantly simplifies the transfer of a bending tool from the upper beam or the lower beam to the bending tool holder unit or vice versa for the operator of the bending press.

Bei einer Ausführung, bei der die zumindest eine Teileaufnahmeeinheit auf die Höhe der Biegelinie der Biegepresse versetzbar und/oder verschwenkbar ist, wird dadurch beispielsweise die Entnahme des entsprechenden Teils für den Bediener der Biegepresse wesentlich vereinfacht.In an embodiment in which the at least one part receiving unit can be moved and/or pivoted to the level of the bending line of the bending press, this significantly simplifies the removal of the corresponding part for the operator of the bending press, for example.

Vorzugsweise ist eine Halteeinrichtung zum temporären Halten der zumindest einen Biegewerkzeugaufnahmeeinheit und/oder der zumindest einen Teileaufnahmeeinheit in der zumindest einen Schublade vorgesehen, so dass die zumindest eine, versetzbare Biegewerkzeugaufnahmeeinheit und/oder die zumindest eine, versetzbare Teileaufnahmeeinheit nicht unbeabsichtigt, z.

Die in der Fig. 1 gezeigte Biegepresse 11 weist eine Oberwange 21 und eine Unterwange 26 auf, wobei zum Biegen von Blechen die Oberwange 21 relativ zur Unterwange 26 verfahrbar ist. Je nach Art der zu erstellenden Biegung werden die entsprechenden Biegewerkzeuge an der Oberwange 21 und der Unterwange 26 vorgesehen. Innerhalb des Gehäuses 13 der Biegepresse 11 sind die Steuerung, das Antriebsmittel für die Oberwange 21 sowie die anderen üblichen Komponenten einer herkömmlichen Biegepresse 11 vorgesehen.The one in the 1 The bending press 11 shown has an upper beam 21 and a lower beam 26, the upper beam 21 being movable relative to the lower beam 26 for bending sheet metal. Depending on the type of bend to be created, the corresponding bending tools are provided on the upper beam 21 and the lower beam 26 . Inside the housing 13 of the press brake 11, the control, the drive means for the upper beam 21 and the other usual components of a conventional press brake 11 are provided.

Im vorliegenden Beispiel sind beidseitig neben der Unterwange 26 zwei Schubladen 31, 31A angeordnet, die zur Aufnahme von Biegewerkzeugen ausgebildet sind. Die Schubladen 31, 31A sind in das Gehäuse 13 der Biegepresse 11 integriert.In the present example, two drawers 31, 31A, which are designed to accommodate bending tools, are arranged on both sides next to the lower beam 26. The drawers 31, 31A are integrated into the housing 13 of the bending press 11.

Jede Schublade 31, 31A ist über Führungsschienen 34 auf einem entsprechend ausgebildeten, im Gehäuse 13 der Biegepresse 11 vorgesehenen Schubladenmechanismus geführt. Vorteilhaft ist eine Auszugssperre vorgesehen, welche verhindert, dass die Schublade 31, 31A versehentlich zu weit aus dem Gehäuse 13 der Biegepresse 11 herausgezogen werden kann. Zudem können Fixiersicherungen für die Schubladen 31, 31A vorgesehen sein, um diese in bestimmten Stellungen relativ zu dem Gehäuse 13 der Biegepresse 11 fixieren und dadurch ein unbeabsichtigtes Schliessen derselben verhindern zu können.Each drawer 31, 31A is guided via guide rails 34 on a correspondingly designed drawer mechanism provided in the housing 13 of the bending press 11. A pull-out lock is advantageously provided, which prevents the drawer 31, 31A from being accidentally pulled too far out of the housing 13 of the bending press 11. In addition, locking devices for the drawers 31, 31A can be provided in order to fix them in certain positions relative to the housing 13 of the bending press 11 and thereby prevent them from being closed unintentionally.

In diesem Beispiel ist die Schublade 31 über eine Motoreinheit 48 verfahrbar, wobei diese Motoreinheit 48 über einen Sensor 49 - hier als Bewegungssensor ausgebildet - gesteuert ist.In this example, the drawer 31 can be moved via a motor unit 48, this motor unit 48 being controlled via a sensor 49--designed here as a movement sensor.

Die Schublade 31 ist mit einem Schloss 35 versehen. Mit dem entsprechenden Schlüssel als Schliessmittel kann die Schublade 31 verriegelt beziehungsweise blockiert werden.The drawer 31 is provided with a lock 35. The drawer 31 can be locked or blocked with the appropriate key as the locking means.

Jede Schublade 31, 31A weist weiter einen Aufnahmebereich 32 auf, in dem mehrere Biegewerkzeugaufnahmeeinheiten 36 für Biegewerkzeuge vorgesehen sind (Figuren 2 und 3). Jede dieser Biegewerkzeugaufnahmeeinheiten 36 weist eine Aufnahmehalterung 37 für ein Biegewerkzeug auf, in welchen das Biegewerkzeug beispielsweise klemmend gehalten ist. Die Aufnahmehalterung 37 ist beispielsweise aus einem Schaumstoff gefertigt und weist - in diesem Beispiel -jeweils drei Aufnahmeschlitze 39 zur Aufnahme von zumindest drei Biegewerkzeugen auf.Each drawer 31, 31A also has a receiving area 32 in which several bending tool receiving units 36 for bending tools are provided ( figures 2 and 3 ). Each of these bending tool receiving units 36 has a receiving holder 37 for a bending tool, in which the bending tool is held, for example in a clamped manner. The mounting bracket 37 is made, for example, from a foam material and has - in this example -each three receiving slots 39 for receiving at least three bending tools.

An jeder Biegewerkzeugaufnahmeeinheit 36 ist jeweils eine entlang deren Längserstreckung verlaufende Anzeigeeinheit 43 sowie eine entlang deren Quererstreckung verlaufende Anzeigeeinheit 44 vorgesehen. Diese Anzeigeeinheiten 43 und 44 sind jeweils als LED-Lichtstreifen ausgebildet, wobei die einzelnen LEDs separat ansteuerbar sind. Über diese LEDs wird dem Bediener beispielsweise angezeigt, wo er ein nicht mehr benötigtes Biegewerkzeug einlagern soll. Über diese LEDs kann dem Bediener beispielsweise auch angezeigt werden, welches Biegewerkzeug er aus der Biegewerkzeugaufnahmeeinheit 36 für den nächsten Biegevorgang in der Unterwange 26 oder der Oberwange 21 anordnen soll.Provided on each bending tool receiving unit 36 is a display unit 43 running along its longitudinal extension and a display unit 44 running along its transverse extension. These display units 43 and 44 are each designed as LED light strips, with the individual LEDs being able to be controlled separately. These LEDs show the operator, for example, where to store a bending tool that is no longer required. These LEDs can also be used, for example, to indicate to the operator which bending tool he should arrange from the bending tool receiving unit 36 in the lower beam 26 or the upper beam 21 for the next bending process.

Jede der Biegewerkzeugaufnahmeeinheiten 37 ist aus dem Aufnahmebereich 32 der entsprechenden Schublade 31 versetzbar. Im vorliegenden Beispiel (siehe insb. Fig. 4) ist jede Biegewerkzeugaufnahmeeinheit 37 um eine, hier durch einen Bolzen definierte Schwenkachse 38 aus dem Aufnahmebereich 32 der Schublade 31 herausschwenkbar.Each of the bending tool receiving units 37 can be moved out of the receiving area 32 of the corresponding drawer 31 . In the present example (see esp. 4 ) each bending tool receiving unit 37 can be pivoted out of the receiving area 32 of the drawer 31 about a pivot axis 38 defined here by a bolt.

Weiter sind Halteeinrichtungen 40 zum temporären Halten der Biegewerkzeugaufnahmeeinheiten 36 in der Schublade 31 vorgesehen. Die Halteeinrichtungen 40 weisen beispielsweise einen an der Biegewerkzeugaufnahmeeinheit 36 angeordneten Magneten 42 und einen an der Innenseite des Aufnahmebereichs 32 der entsprechenden Schublade 31 angeordneten Gegenmagneten 41 auf. Der Magnet 42 wie auch der Gegenmagnet 41 sind derart ausgebildet, dass die Biegewerkzeugaufnahmeeinheit 36 beim Öffnen und Schliessen der Schublade temporär gehalten ist, jedoch die vorhandene Haltekraft zwischen dem Magneten 42 und dem Gegenmagneten 41 vom Bediener einfach und vorteilhaft ohne grossen Kraftaufwand überwunden werden kann.Furthermore, holding devices 40 for temporarily holding the bending tool receiving units 36 in the drawer 31 are provided. The holding devices 40 have, for example, a magnet 42 arranged on the bending tool receiving unit 36 and a counter-magnet 41 arranged on the inside of the receiving area 32 of the corresponding drawer 31 . The magnet 42 and the counter-magnet 41 are designed in such a way that the bending tool holder unit 36 is held temporarily when the drawer is opened and closed, but the existing holding force between the magnet 42 and the counter-magnet 41 can be easily and advantageously overcome by the operator without great effort.

In Bezug auf die vorliegende Darstellung im oberen Bereich der Schublade 31 weist diese eine Teileaufnahmeeinheit 33 auf, welche die Schublade 31 von oben her abdeckt und die in den Biegewerkzeugaufnahmeeinheiten 36 vorhandenen Biegewerkzeuge wenigstens teilweise schützt. Diese Teileaufnahmeeinheit 33 dient beispielsweise der Aufnahme von Werkzeugen für den Maschinenunterhalt oder für das Anordnen beziehungsweise Wechseln von Biegewerkzeugen an der Oberwange 21 und/oder der Unterwange 26. Weiter können auch Messmittel, insbesondere die Messmittel, die beim Biegen des Blechs benötigt werden, in der Werkzeugaufnahme 33 gelagert werden. Somit stehen dem Bediener der Biegepresse 11 sämtliche für deren Bedienung benötigten Arbeitsmittel direkt an der Biegepresse 11 zur Verfügung.With reference to the present illustration, in the upper area of the drawer 31, the latter has a parts receiving unit 33, which covers the drawer 31 from above and at least partially protects the bending tools present in the bending tool receiving units 36. This parts receiving unit 33 is used, for example, to hold tools for machine maintenance or for arranging or changing bending tools on the upper beam 21 and/or the lower beam 26. Measuring equipment, in particular the measuring equipment required for bending the sheet metal, can also be stored in the Tool holder 33 are stored. Thus, the operator of the bending press 11 has all the work equipment required for its operation directly at the bending press 11 .

In der Teileaufnahmeeinheit 33 ist eine Induktionsfläche als eine elektrische Schnittstelle 121 vorgesehen, über welche induktionsfähige Geräte bedarfsweise geladen werden können. Weiter ist eine elektronische Schnittstelle 123 - hier in Form eines USB-Anschlusses - vorgesehen, über die beispielsweise Daten mit der Schublade 31 und/oder mit der Biegepresse 11 austauschbar sind.An induction surface is provided in the parts receiving unit 33 as an electrical interface 121, via which induction-capable devices can be charged as required. An electronic interface 123—here in the form of a USB connection—is also provided, via which, for example, data can be exchanged with the drawer 31 and/or with the bending press 11 .

Weiter ist in beziehungsweise bei der Teileaufnahmeeinheit 33 eine Kontrollelektronik 125 vorgesehen, welche über entsprechende Sensoren 127 oder Einrichtungen (z. B. eine Kamera) Kontrollen an den Biegeteilen und/oder an den Biegewerkzeugen vornehmen kann. Beispielsweise dient diese Kontrollelektronik 125 dem Erfassen eines IST-Zustandes eines Biegewerkzeuges.Furthermore, an electronic control system 125 is provided in or near the parts receiving unit 33, which can carry out checks on the bent parts and/or on the bending tools via corresponding sensors 127 or devices (e.g. a camera). For example, this control electronics 125 is used to record an actual state of a bending tool.

Die Schublade 31 ist zudem gegenüber dem Gehäuse 13 der Biegepresse 11 um die Rotationsachse 46 verschwenkbar und entlang dieser relativ zu dem Gehäuse 13 der Biegepresse 11 versetzbar (siehe Fig. 4). Entsprechend kann die Schublade 31 entlang der Rotationsachse 46 in der Höhe bedarfsweise positioniert werden. Auch kann die Schublade 31 derart verschwenkt werden, dass der Tätigkeitsraum des Bedieners der Biegepresse 11 weniger von der Schublade 31 begrenzt beziehungsweise nur geringfügig eingeschränkt wird.The drawer 31 can also be pivoted about the axis of rotation 46 relative to the housing 13 of the bending press 11 and can be displaced along this axis relative to the housing 13 of the bending press 11 (see FIG 4 ). Accordingly, the height of the drawer 31 can be positioned along the axis of rotation 46 as required. The drawer 31 can also be pivoted in such a way that the area where the operator of the bending press 11 can work is less limited by the drawer 31 or only slightly restricted.
