Embodiment Construction

[0028] for the manner in which the invention is carried out

[0029] Next, the extruder apparatus and the control method of the extruder according to the present invention will be described in detail with reference to the drawings.

[0030] Such as figure 1 As shown in the extrusion machine, the end table 10 and the main hydraulic cylinder device 12 are arranged facing each other, and the two are connected by a plurality of tie rods 14 . The extrusion cylinder 18 is arranged on the inner surface side of the end table 10 so as to sandwich the female mold 16 with the extrusion hole formed therein. , the product of the cross section corresponding to the die hole 16A is extruded.

[0031] The main hydraulic cylinder device 12 that generates extrusion force has a main hydraulic head 12B built in the main hydraulic cylinder 12A so that it can push and move toward the above-mentioned extrusion cylinder 18 . The main crosshead 22 is attached to the front end of the main ram 12B, a...

Abstract

The invention provides an extrusion press and a control method for the extrusion press. The extrusion press can prevent phenomena in which a billet is blown out during an extrusion process; and the extrusion press is provided with an assembly which can prevent billet blowout with a simple and inexpensive constitution. The extrusion press drives a main cylinder device (12) to extrude, by means of a stem (24), a billet (20) filled into a container (18) from a die (16) and form a product (20A). A gap measurement means (60) that measures a gap, during the extrusion process, arising at the container seal surface formed by pressing the die side end surface of the container (18) against the container side end surface of the die (16) is provided on an end platen (10) on the outer edge part of the container side end surface of the die (16). When the gap arising during the extrusion process is measured and the measured value is within a predetermined range of allowable values, a set value for the extrusion rate is lowered and a warning is issued. When the measured value exceeds the predetermined allowable values, the extrusion process is stopped.

Description

technical field [0001] Cross-references related to related applications [0002] This invention is based on the priority application patent of the Japanese patent application "Japanese Patent Application No. 2011-192212" of September 5, 2011, and those contents are incorporated in this specification as a reference, and are continued in this application. [0003] The present invention relates to an extruder for aluminum alloys and a control method for the extruder, and particularly relates to an extruder that can prevent leakage of metal from the gap between the extruder cylinder and the die in the extruder process and improve the yield of the product. Machine and extrusion machine control method. Background technique [0004] A conventional extrusion machine has an end table and a main hydraulic cylinder device connected by tie rods. On the end table side, an extrusion cylinder filled with a billet is arranged with the female mold sandwiched between them. The piston of thi...
