Title (EN) PRESS AND METHOD FOR PRODUCING THE MOULDED PART
(FR) PRESSE ET PROCÉDÉ POUR LA FABRICATION DE LA PIÈCE MOULÉE
(DE) PRESSE UND VERFAHREN ZUM HERSTELLEN DES FORMTEILS
Abstract:
(EN) The invention relates to a press comprising a press frame (2), having an upper beam (3) and a lower beam (4), an upper tool (la) and a lower tool (lb) provided on the lower beam (4) for producing a moulded part, at least one press cylinder (8) provided on the upper beam (3) and having a piston (9) which is joined to the upper tool (la) via a bearing (10) and configured to exert a pressing force on the moulded part, and a compensation means (12) provided on the bearing, which is configured to exert a variably adjustable compensation force opposing the pressing force on the piston (9) and the upper tool (la) in order to compensate for at least one play generated by a weight force of the upper tool (la) between the piston (9) and the upper tool (la).
(FR) Presse comprenant un châssis de presse (2) comprenant une traverse supérieure (3) et une traverse inférieure (4), un outil supérieur (la) et un outil inférieur (lb) prévu sur la traverse inférieure (4) pour la fabrication d’une pièce moulée, au moins un vérin de pression (8) prévu sur la traverse supérieure (3), comprenant un piston (9) qui est articulé sur l’outil supérieur (la) au moyen d’un palier (10) et qui est conçu pour exercer une force de pression sur la pièce moulée, et un moyen de compensation (12), conçu pour exercer sur le piston (9) et sur l’outil supérieur (la) une force de compensation réglable de façon variable et opposée à la force de pression, afin de compenser un jeu entre le piston (9) et l’outil supérieur (la) généré par le poids de l’outil supérieur (la).
(DE) Presse mit einem einen Oberholm (3) und einen Unterholm (4) aufweisenden Pressengestell (2), einem Oberwerkzeug (la) und einem an dem Unterholm (4) vorgesehenen Unterwerkzeug (Ib) zum Herstellen eines Formteils, wenigstens einem an dem Oberholm (3) vorgesehenen Presszylinder (8) mit einem Kolben (9), welcher an dem Oberwerkzeug (la) über ein Lager (10) angelenkt und ausgeführt ist, eine Presskraft auf das Formteil auszuüben, und einem an dem Lager vorgesehenen Kompensationsmittel (12), welches ausgeführt ist, auf den Kolben (9) und das Oberwerkzeug (la) eine der Presskraft entgegengesetzt wirkende und variabel einstellbare Kompensationskraft auszuüben, um wenigstens ein durch eine Gewichtskraft des Oberwerkzeugs (la) erzeugtes Spiel zwischen Kolben (9) und Oberwerkzeug (la) zu kompensieren.
