Haltefläche an BogengreifereinrichtungenHolding surface on sheet gripper devices
Anwendungsgebietfield of use
Die Erfindung betrifft eine Haltefläche an Bogengreifereinrichtungen in bogenbe- und -verarbeitenden Maschinen.The invention relates to a holding surface on sheet gripper devices in sheet metal processing machines.
Charakteristik der bekannten technischen LösungenCharacteristics of the known technical solutions
Es sind Halteflächen an Bogengreifereinrichtungen bekannt, wobei die Haltefläche mit einem Profil versehen ist, das aus dem Grundmaterial der Haltefläche besteht (DE-PS 1 411 126). Nachteilig ist dabei, daß das Profil der Halteflächen aus dem relativ weichen Grundmaterial der Halteflächen besteht und dadurch keine genügende Festigkeit gegen Verschleiß aufweist. Bekannte verschleißmindernde Maßnahmen, wie Härten, erfordern infolge Verzug Nachbearbeitungen des Profils, wodurch Profilunregelmäßigkeiten und damit Haltekraftverringerungen eintreten.There are holding surfaces on sheet gripper devices known, the holding surface is provided with a profile that consists of the The base material of the holding surface is made (DE-PS 1 411 126). The disadvantage here is that the profile of the holding surfaces from the There is relatively soft base material of the holding surfaces and therefore does not have sufficient strength against wear. Known wear-reducing measures, such as hardening, require post-processing of the profile as a result of distortion, which results in profile irregularities and thus a reduction in holding force occurs.

Ziel der ErfindungObject of the invention
Ziel der Erfindung ist es, Halteflächen an Bogengreifereinrichtungen zu schaffen, die eine hohe Verschleißfestigkeit aufweisen und ökonomisch herstellbar sind.The aim of the invention is to provide holding surfaces on sheet gripper devices to create that have a high wear resistance and can be produced economically.
Aufgabe der ErfindungObject of the invention
Die Aufgabe der Erfindung besteht darin, ein Verrutschen der Bogen zwischen den Halteflächen von Bogengreifer und Bogengreiferaufschlag durch eine Verringerung der Haltekraft infolge von Abnutzungserscheinungen der profilierten Haltefläche zu vermeiden. The object of the invention is to prevent the sheets from slipping between the holding surfaces of the sheet gripper and sheet gripper impact by reducing the holding force as a result of wear and tear on the profiled holding surface.
Wesen der ErfindungEssence of the invention
Merkmale der Erfindung sind, daß die mit einem Profil versehene Haltefläche mit einer Schicht aus Feinstkornmetalloxyd oder -carbid dünn beschichtet ist, wobei die mittlere Größe der in der Schicht enthaltenen Körner 10 pn beträgt und die Schicht aus Peinstkornmetalloxyden oder -carbiden der Metalle Chrom, Wolfram, Titan oder Aluminium besteht.Features of the invention are that the holding surface provided with a profile is thinly coated with a layer of fine grain metal oxide or carbide, the mean size of the grains contained in the layer being 10 pn and the layer of fine grain metal oxides or carbides of the metals chromium and tungsten , Titanium or aluminum.
AusführungsbeiepielExecution example
Die Erfindung soll nachstehend an einem Aueführungsbeispiel näher erläutert werden.The invention is to be explained in more detail below using an exemplary embodiment.
Die dazugehörige Zeichnung zeigt einen Schnitt durch eine mit einem Profil versehene Haltefläche.The accompanying drawing shows a section through a holding surface provided with a profile.

Λ-Λ-
Die Zeichnung zeigt einen Schnitt durch eine Haltefläche 1 einer nicht dargestellten Bogengreifereinrichtung« Die Haltefläche 1 ist mit einem gleichmäßigen Profil 2 versehen. Das Profil 2, das aus dem Grundmaterial 3 der Haltefläche 1 besteht, wird mit einer Schicht 4 aus pulverisierten Feinstkornmetalloxyd oder -carbid beschichtet. Die mittlere Größe der in dem Feinstkornmetalloxyd oder -carbid enthaltenen Körner 5 beträgt vorzugsweise 10 ^um. Das Feinstkornmetalloxyd oder -carbid kann aus den Metallen Chrom, Wolfram, Titan oder Aluminium bestehen. Mit der erfindungsgemäßen Pulverbeschichtung der Profile wird erreicht, daß das weiche mit Profilen versehene Grundmaterial auf ökonomische Weise mit einer verschleißfesten Haltefläche versehen wird und dadurch eine Verringerung der Haltekraft infolge von Abnutzungserscheinungen der profilierten Haltefläche vermieden wird. Die Regelmäßigkeit der Profile wird dadurch nicht beeinflußt.The drawing shows a section through a holding surface 1 of a sheet gripper device (not shown) is provided with a uniform profile 2. The profile 2 that consists of the base material 3 of the holding surface 1, is coated with a layer 4 of powdered fine grain metal oxide or -carbide coated. The mean size of the grains 5 contained in the fine grain metal oxide or carbide is preferably 10 ^ um. The fine grain metal oxide or carbide can from the Metals consist of chrome, tungsten, titanium or aluminum. With the powder coating according to the invention, the profile is achieves that the soft profiled base material in an economical manner with a wear-resistant holding surface is provided and thereby a reduction in the holding force due to wear and tear of the profiled holding surface is avoided. This does not affect the regularity of the profiles.
