Description

Presse zum Verformen von Blech Die Erfindung bezieht sich auf eine Presse zum Verformen von Blech, die einen Hauptstempel und in diesem angeordnete, unabhängig über eine Pumpe hydraulisch angetriebene Nebenstempel aufweist.Press for deforming sheet metal. The invention relates to a Press for deforming sheet metal, which has a main punch and, arranged in this, has independently hydraulically driven auxiliary ram via a pump.

Bei einer bekannten Presse zur Blechverformung der vorgenannten Art ist der Hauptstempel mit den Nebenstempeln am feststehenden Teil der Presse und die Matrize am angetriebenen Pressenstößel angeordnet. Bei der umgekehrten Anordnung, bei der die Stempel am Pressenstößel angeordnet sind, ist es nicht ohne weiteres möglich, die Nebenstempel unabhängig von dem Hauptstempel anzutreiben. Dies könnte zwar üblicherweise dadurch erfolgen, daß die Nebenstempel über eine gesonderte Pumpe am Pressengestell hydraulisch angetrieben werden. Bei größeren von dem Hauptstempel zurückzulegenden Strecken besteht dann aber die Schwierigkeit, daß die Druckmittelzuleitungen zu den Nebenstempeln beweglich, z. B. als Druckschläuche, ausgebildet sein müssen und auch bei guter Verlegung ständig der Gefahr einer Beschädigung ausgesetzt sind.In a known press for sheet metal deformation of the aforementioned type is the main stamp with the secondary stamps on the fixed part of the press and the die is arranged on the driven press ram. In the reverse arrangement, in which the punches are arranged on the press ram, it is not straightforward possible to drive the secondary stamp independently of the main stamp. this could it is usually done in that the secondary ram has a separate pump are hydraulically driven on the press frame. For larger ones from the main postmark The distances to be covered then, however, have the difficulty that the pressure medium supply lines movable to the secondary stamps, z. B. must be designed as pressure hoses and are constantly exposed to the risk of damage even with good installation.

Der Erfindung liegt die Aufgabe zugrunde, einen einfachen und betriebssicheren hydraulischen Antrieb der Nebenstempel zu schaffen, der unabhängig von dem Hauptstempel arbeiten kann.The invention is based on the object of a simple and operationally reliable hydraulic drive to create the secondary ram, which is independent of the main ram can work.

Zur Lösung dieser Aufgabenstellung sieht die Erfindung vor, daß bei Anordnung der Nebenstempel an dem in der Presse verschiebbaren Pressenstößel dieser auch die Pumpe für den Antrieb der Nebenstempel trägt. Durch diese Maßnahme wird erreicht, daß die Gefahr einer Beschädigung der Druckmittelzuleitungen auf ein Mindestmaß herabgesetzt wird. Die Druckmittelzuleitungen können fest an dem Pressenstößel verlegt werden und sind daher keinen äußeren Beanspruchungen unterworfen.To solve this problem, the invention provides that at Arrangement of the auxiliary punches on the press ram, which can be moved in the press also carries the pump for driving the auxiliary ram. This measure will achieved that the risk of damage to the pressure medium supply lines to a minimum is reduced. The pressure medium supply lines can be laid firmly on the press ram are and are therefore not subject to any external stresses.

Die Erfindung ist im folgenden an Hand der Zeichnung, in der eine Presse im Schnitt dargestellt ist, beispielsweise näher erläutert.The invention is described below with reference to the drawing, in which a Press is shown in section, for example explained in more detail.

Ein Druckmittelzylinder a treibt einen an Führungen b verschiebbar gelagerten Pressenstößel c an. Die Führungen b sind in Endplatten d und e gehalten. Der Pressenstößel c trägt einen Hauptstempel f, während an der dem Hauptstempel gegenüberliegenden Endplatte e eine Hauptmatrize g befestigt ist. Ein zu verformendes Werkstück ist in der Zeichnung mit h angegeben.A pressure cylinder a drives a press ram c, which is slidably mounted on guides b. The guides b are held in end plates d and e. The press ram c carries a main punch f, while a main die g is attached to the end plate e opposite the main punch. A workpiece to be deformed is indicated by h in the drawing.

Mit dem Pressenstößel c ist eine Pumpe m fest verbunden, die über Druckmittelleitungen n Arbeitszylinder o speist, von denen Nebenstempel p betätigt werden. Den Nebenstempeln. p sind Nebenmatrizen q in der Hauptmatrize g zugeordnet.A pump m is firmly connected to the press ram c and feeds n working cylinders o via pressure medium lines, from which auxiliary rams p are actuated. The secondary stamps. p are associated with secondary matrices q in the main matrix g.
