Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Biegen und/oder Stanzen und/oder Stauchen von Draht- oder streifenartigen Blechteilen, bei der an einem Maschinentisch geführt mehrere über hydraulische-mechanische Geber angetriebene und elektronisch gesteuerte Werkzeuge angeordnet sind.The invention relates to a device for bending and / or punching and / or upsetting wire or strip-like sheet metal parts, at the one machine table guided several hydraulic-mechanical Encoder driven and electronically controlled tools arranged are.
Insbesondere bei derartigen Biegevorrichtungen ist es bekannt, auf einem horizontal oder vertikal angeordneten Arbeitstisch mehrere nacheinander oder parallel arbeitende Werkzeuge auf Schlitten anzuordnen, die entsprechend eingebrachte Drahtteile an mehreren Stellen gesteuert verbiegen sowohl in verschiedenen Ebenen als auch unter verschiedenen Winkeln. Zur Verbiegung von durchmesserstarken Drahtteilen, insbesondere dann, wenn lange Biegewege vorgesehen sind, ist es bekannt, eine hydraulische Pumpeneinheit vorzusehen, über die die Ölversorgung zu den den einzelnen Werkzeugen zugeordneten Gebern erfolgt. Diese Geber sind Hydraulikzylinder, in die das von der Zentraleinheit gesteuert geführte Öl hineingedrückt bzw. aus denen das Öl wieder abgeleitet wird. Es ist dabei bekannt, die Steuerung der einzelnen Geber und damit der Werkzeuge elektronisch zu steuern in der Art einer sogenannten CNC-Steuerung. Bei solchen Vorrichtungen mit einer Vielzahl von Biegewerkzeugen mit unterschiedlichen Biegewegen ist es erforderlich, eine leistungsstarke Zentraleinheit, also eine leistungsstarke Hydraulikpumpe vorzusehen, über die entsprechend der Zahl der Werkzeuge und deren Zuleitungen relativ große Hydraulikölmengen umgepumpt werden müssen. Eine solche Hydraulikversorgung ist sehr aufwendig und beeinflußt in starkem Maße die Arbeitsgeschwindigkeit.In particular with such bending devices, it is known to use a horizontally or vertically arranged work table several in succession or to arrange tools working in parallel on slides, the corresponding Bend the inserted wire parts in several places in a controlled manner both in different planes and at different angles. For bending wire parts of large diameter, in particular when long bending paths are provided, it is known to be a hydraulic one To provide a pump unit through which the oil supply to the sensors assigned to the individual tools. These donors are hydraulic cylinders into which the control unit is guided Oil pressed in or from which the oil is drained off again. It is known, the control of the individual encoder and thus the tools to be controlled electronically in the manner of a so-called CNC control. In such devices with a variety of bending tools with different bending paths it is necessary to have a powerful one Central unit, i.e. a powerful hydraulic pump to provide about the according to the number of tools and their Supply lines have to be pumped relatively large amounts of hydraulic oil. Such a hydraulic supply is very complex and affects in greatly the speed of work.
Die Aufgabe der Erfindung besteht darin, die Arbeitsgeschwindigkeit einer Vorrichtung der eingangs genannten Art zu erhöhen und die Einrichtbarkeit einer solchen Vorrichtung zu verbessern und flexibler zu gestalten. The object of the invention is to determine the working speed Device of the type mentioned to increase and the ability to set up to improve such a device and make it more flexible.
Gelöst wird die Erfindungsaufgabe durch eine Vorrichtung mit den Merkmalen
des Anspruchs 1.The task of the invention is solved by a device with the features
of
Durch die Zuordnung jeweils eines eigenen Elektroantriebes zu jedem Werkzeug wird zum einen erreicht, daß lediglich kleine Antriebseinheiten zu verwenden sind und andererseits, daß aufgrund der damit verbundenen geringen Ölmengen hohe Arbeitsgeschwindigkeiten der Werkzeuge erreicht werden können. Über unterschiedliche Flächenverhältnisse können unterschiedliche Kräfte erzeugt werden.By assigning a separate electric drive to each Tool is achieved on the one hand that only small drive units are to be used and on the other hand that due to the associated low oil quantities high tool working speeds can be achieved. Can use different surface ratios different forces are generated.
Bevorzugte Ausführungsarten einer erfindungsgemäßen Vorrichtung werden
mit den Unteransprüchen angegeben. Es erweist sich als besonders
vorteilhaft um kleine Elektromotoren verwenden zu können bei relativ hohen
zu erreichenden Hydraulikdrücken eine Kraftübertragung entsprechend
den Merkmalen des Anspruchs 3 vorzusehen mit dem genannten
Getriebe.Preferred embodiments of a device according to the invention are
specified with the subclaims. It turns out to be special
advantageous to be able to use small electric motors with relatively high ones
to achieve hydraulic pressures corresponding to a power transmission
to provide the features of
