Problems solved by technology

(1) Because the working oil is used as the medium, it is difficult to realize the absolute speed and position of the mechanical movement
(2) The consumption of energy is relatively large. In addition, in order to prevent the rise of oil temperature, cooling water is required, and the operating cost increases.
(3) There are many structural elements with high circuit pressure, and the noise during operation is high
(4) Because hydraulic oil is used, there are maintenance, environmental, and cost problems caused by leakage of hydraulic oil, and environmental and cost problems associated with the disposal of hydraulic oil

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).

Description

technical field [0001] The present invention relates to an extruder, in particular to an extruder device for extruding an aluminum alloy or the like through a female die (or a plurality of female dies), and more specifically, to an injection molding machine (or Die-casting aluminum alloy die-casting machine) is an electric-driven extruder that applies an electric drive type. Background technique [0002] Extrusion machines are used to extrude and form metal products such as aluminum window frames. In the conventional extruder, the billet used as the material is filled in the fixed extrusion cylinder, extruded by the extrusion rod (or shaft), and passed through the extrusion cylinder installed in the extrusion cylinder. The female die (mold) of the outlet is shaped into a prescribed cross-sectional shape, and the extrusion rod (or shaft) is driven by a piston hydraulic cylinder. The billets loaded in such a molding machine are supplied by a billet loader, and the billet loa...
