摘要： A method of cleaning an extrusion die from residual metal remaining after an extrusion process at a temperature below 600° C. and of recovering the residual metal includes providing a thrust member with at least one portion made of a polymeric material at the extrusion die; reciprocally moving the thrust member and the die; removing polymeric material not flowed out of the die during the preceding step; mechanically and/or chemically removing the residual metal not flowed out from the die during the moving step; and opening the extrusion die. The polymeric material in the moving step has a water content lower than 7% by weight with respect to the total weight of the polymeric material. During the moving step, the polymeric material is at least partially in a plastic deformation condition or melted so as to occupy the volume of the residual metal flowed out of the extrusion die.

摘要： An extrusion method using an extrusion press including an end platen to which a pressure ring is provided, a die, a container, a drive part for movement of the container, and a main cylinder device having an extrusion stem to form a billet into a shape includes extruding the billet loaded in the container by the extrusion stem from the die to shape it to an extruded material, releasing sealing pressure from the die, cutting the billet between the die and the container and between the die and the pressure ring by moving the die, and resuming shaping of extruded materials by the billet remaining inside the container.

摘要： A shear device (21) of an extrusion press having a booster mechanism using an air cylinder or electric motor to supplement thrust to an amount corresponding to hydraulic pressure is provided. A fastening part pressing against a die stack (4) is configured by a booster mechanism using a lever and a shear guide (24) is pressed against a horseshoe (13) to fasten it in the extrusion direction. Further, a clearance between a surface of the die stack and a shear knife can be held constant. Also, a booster mechanism using a lever is employed for a tilt mechanism for the shear guide in the extrusion press.

摘要： A process for extruding a section or the like body from an ingot is such that an ingot is introduced into a bore of a container and, by means of an extrusion stem, is fed in the direction of extrusion into a shape-giving opening in a die. Before the ingot enters the die opening, it is pushed out of the container by an amount corresponding to the width (t) of a collar whereupon a disk-shaped slice is sheared off the free end of the ingot and removed. The free end of the ingot is then pushed onto the die opening. In order to carry out this process, a shearing tool is provided after the end of the container facing the die and a movable shearing blade positioned over that entrance to the container bore. The disk-shaped slice should preferably be sheared away together with a residual butt of the previously extruded ingot which faces away from the die. To that end, a shearing tool with two shearing blades is provided and can be moved radially with respect to the longitudinal axis (A) of the container bore.

摘要： This invention provides an indirect metal extrusion method, in which free die system is adopted. A die (8) of two-stepped structure is capable of removing shell or outer layer of a billet simultaneously at the time of extrusion, and eliminating the container cleaning cycle after the extrusion. Besides, a shear support (3), an independent body of the container (2), is disposed on the nearer side of the container (2) to an extrusion ram (4), so that discard integrally clung to the die (8) may be served after finishing of an extrusion stroke off the die (8) which is rested on the shear support (3) by means of a shear (14) or a shearing apparatus. This method enables shortening of the extrusion cycle and eliminating damage to principal structure of the extruder.

摘要： A press operated by the reverse method comprising a fixed tubular die casing defining a pressing axis, a main jack operative to displace a cross beam supported for displacement along the pressing axis, a displaceable holder disposed between the cross beam and the tubular die casing and having a bore disposed along the pressing axis for receiving a billet to be pressed. The bore has open ends and the holder is capable of fitting over the die casing by axial displacement thereof. A closure member is carried by a slide for closing one end of the bore in the holder; the slide is displaceable on the cross beam transversely with respect to the pressing axis. A support is slidably mounted parallel to the slide and is carried by an auxiliary cross beam which is slidably mounted on the main cross beam for movement parallel to the pressing axis. The support and the slide are simultaneously displaceable under the action of a jack or other suitable device. A rod is connected to the support and is slidably mounted axially in the slide for operating auxiliary members slidably mounted in the slide.
