Description
Den Gegenstand der Erfindung bildet eine hydraulische Streckziehpresse, bei welcher auf zwei gegenüberliegenden Seiten des die Preßform tragenden Preßstempels mehrere Ein-Spannblöcke für das Blech angeordnet sind. Für die Verformung größerer Werkstücke hat man bislang entweder entsprechend große Streckziehpressen verwendet, die bei kleineren Werkstücken eine unwirtschaftliche Arbeitsweise ergaben, oder man hat eine Verbreiterung der -Presse durch Ansetzen einer zweiten oder weiterer Pressen vorgenommen, was umständlich ist. Diese Maßnahme erfordert zudem die Anschaffung einer entsprechenden Anzahl Pressen, die nur zeitweise Verwendung finden.The subject of the invention is a hydraulic stretch drawing press, in which on two opposite sides of the press die carrying the die several one-clamping blocks are arranged for the sheet. For the deformation of larger workpieces, up to now either correspondingly large workpieces have been used Stretch drawing presses are used, which are uneconomical for smaller workpieces Working method resulted, or you have a widening of the press by attaching made a second or further press, which is cumbersome. This measure also requires the purchase of a corresponding number of presses, which only temporarily Find use.
Die Erfindung betrifft eine Verbesserung an Streckpressen, durch- die vorstehende Mangel behoben sind. Gemäß der Erfindung ist die Streckpresse mit seitlichen tischartigen Ansätzen am Pressenbett zum Tragen mehrerer Spannblöcke versehen·.The invention relates to an improvement in stretch presses due to the above deficiency are fixed. According to the invention, the stretching press is provided with side table-like extensions provided on the press bed to carry several clamping blocks ·.
Durch diese Ausbildung ist eine Streckpresse mit veränderlicher Breite geschaffen, die in vorteilhafter Weise eine billige Her- - stellung ermöglicht, weil für große Werkstücke nicht eine Verbreiterung der teueren Fundamente vorgenommen werden muß, sondern verhältnismäßig billige kleine tischartige Ansätze zur Aufnahme der erforderliehen weiteren Spannblöcke Verwendung finden. Dadurch wird auch eine wirtschaftliche Betriebsweise der Presse ermöglicht.This training creates a stretching press with a variable width, which advantageously enables inexpensive manufacture - because for large workpieces the expensive foundations do not have to be broadened, but relatively cheap small table-like approaches to accommodate the required borrowed other clamping blocks are used. This also enables the press to be operated economically.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. An exemplary embodiment of the subject matter of the invention is shown in the drawing.
An dem Streckpressenbett 8 sind tischartige Ansätze 4 seitlich' angeordnet, auf denen weitere Spannblöcke 3 befestigt werden können, wenn das zu verformende Werkstück eine über die Breite des Pressenbettes hinausgehende Ausdehnung aufweist. Diese Ansätze 4 sind vorzugsweise abnehmbar vorgesehen, damit sie bei kleineren Werkstücken das Arbeiten an der Presse nicht behindern.On the stretch press bed 8 table-like extensions 4 are arranged laterally 'on which further clamping blocks 3 can be attached when the workpiece to be deformed has an expansion beyond the width of the press bed. These approaches 4 are preferably provided so that they can be removed so that they do not hinder working on the press with smaller workpieces.
