Abstract:
Disclosed is a fully electric extrusion press with reduced power consumption, improved maintainability and usability, and a reduced negative impact on the environment. Said extrusion press (10) is provided with an end platen (1), a fixed platen (2) disposed behind the end platen, a tie rod (4) that couples the end platen to the fixed platen (2), a die (20), a container (3) filled with billet (8), an extrusion stem (13) that presses on the billet (8), a cross head (7) to which the extrusion stem (13) is attached, and an extrusion drive device that drives the extrusion stem (13) back and forth. The extrusion drive device is provided with a rotatable wire drum (31) driven by an electric main extrusion motor (39). Extrusion molding is performed by rotating the wire drum (31) and taking up wire (32), thereby driving the extrusion stem (13).
