Title
(DE) HYDRAULISCHE ÖLPRESSE
(EN) HYDRAULIC OIL PRESS
(FR) PRESSE À HUILE HYDRAULIQUE
Abstract
(EN) The present disclosure provides an oil hydraulic press including a support frame, at least one main cylinder assembly and at least one fixed die table. The at least one main cylinder assembly includes a cylinder body and a piston connected to the cylinder body, the support frame includes two sets of end frames, the cylinder body is located between the two sets of end frames. Each of the two sets of end frames includes two first buckle frames, and the two first buckle frames are symmetrically arranged around a moving shaft of the piston, one end of each of the two first buckle frames carries the cylinder body, and the other end of each of the two first buckle frames carries the fixed die table. And a pressing mechanism is formed between the piston and the fixed die table. The oil hydraulic press in the present disclosure has following advantages. The main cylinder assembly and the fixed die table can be fixed by the support frame, which forms a ring-like structure, can be operated in one, two or multiple sets in parallel, and all can realize pressing manufacture. The oil hydraulic press has less components, reduced material consumption and low manufacturing cost.
(FR) L’invention concerne une presse à huile hydraulique (100) comprenant un cadre de support (10), au moins un ensemble cylindre d'huile principal (20), et au moins une table de fixation de matrice (30). L'ensemble cylindre d'huile principal comprend un corps de cylindre (21) et un piston (22) relié au corps de cylindre. Le cadre de support comprend deux ensembles de cadres de partie d'extrémité (11). Le corps de cylindre est disposé entre les deux ensembles de cadres de partie d'extrémité. Chaque ensemble de cadres de partie d'extrémité comprend deux premiers cadres de fixation (111). Les deux premiers cadres de fixation sont disposés symétriquement par rapport à un arbre mobile du piston. Une extrémité du premier cadre de fixation porte le corps de cylindre, et l'autre extrémité porte la table de fixation de matrice. Un mécanisme d'ajustement par pression est formé entre le piston et la table de fixation de matrice. La presse à huile hydraulique fixe l'ensemble cylindre d'huile principal et la table de fixation de matrice au moyen du cadre de support pour former un cadre structurel fermé, effectue des opérations d'ajustement par pression à l'aide d'un, de deux ensembles combinés ou plus, et présente une structure compacte et moins de composants, ce qui permet de réduire le poids du matériau et les coûts de fabrication.
