Abstract

PURPOSE: To prevent a billet from cooling in an extrusion press, to adjust the billet temperature, and to prevent the billet surface from oxidation, by installing a waiting space for billets to be extruded, in a stationary platen of a pull-back type indirect extrusion press, and by providing a billet heating element in the said waiting space.
CONSTITUTION: A pull-back type indirect extrusion press is constituted as follows; a couple of mobile platens 1, 2 are arranged on each side of a stationary platen 22 and are connected with each other with tie-rods 3, 3'; main driving cylinders 4, 4' are installed between the stationary platen 22 and mobile platens 1, 2; a space between one mobile platen 2 and the stationary platen 22 is for a billet feeding zone, and a space between another mobile platen 1 and the stationary platen 22 is for an extrusion zone. A waiting space 31 for billets to be extruded is provided with a heating element 29; this waiting space 31 is installed in the stationary platen 22; a billet 18 is heated and warmed by the heating elements 29 within the waiting space 31. In some cases, a gas inlet is provided in the space 31 in order to introduce an antioxidant gas for preventing the billet from oxidation.
