Abstract

a. Presse hydraulique. b. Elle comprend un bâti auquel sont assemblées deux têtes fixes, auxquelles sont fixées les extrémités de deux tiges cylindriques parallèles de coulissement, une traverse fixe portant un poinçon, une traverse coulissante portant un contre-poinçon, et une troisième traverse également coulissante portant une matrice qui délimite les contours de l'objet à presser. Elle est caractérisée en ce qu'il est prévu dans la matrice 15, un dispositif de dosage comprenant un conduit vertical 20 à section rectangulaire, trois parois latérales en matière transparente, la quatrième paroi latérale 21 étant métallique et une électrovalve 18 qui communique avec un tube de transport 26 relié à une trémie c. Fabrication d'objets moulés.at. Hydraulic press. b. It comprises a frame to which are assembled two fixed heads, to which are fixed the ends of two parallel cylindrical sliding rods, a fixed cross member carrying a punch, a sliding cross member carrying a counter-punch, and a third sliding cross member also carrying a die which defines the contours of the object to be pressed. It is characterized in that there is provided in the die 15, a metering device comprising a vertical duct 20 of rectangular section, three side walls made of transparent material, the fourth side wall 21 being metallic and a solenoid valve 18 which communicates with a transport tube 26 connected to a hopper c. Manufacture of molded objects.
