摘要： An extrusion press includes a means which can prevent phenomena in which a billet is blown out during an extrusion process as well as prevent billet blowout with a simple and inexpensive constitution. The extrusion press drives a main cylinder device to extrude, by a stem , a billet filled into a container from a die and form a product. A gap measurement means that measures a gap arising at the container seal surface formed by pressing the die side end surface of the container against the container side end surface of the die is provided on an end platen on the outer edge part of the container side end surface of the die. 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.

摘要： An inner sleeve for a flat extrusion cylinder includes an inner sleeve ring piece, an upper insert piece and a lower insert piece. The inner sleeve ring piece is positioned in an intermediate sleeve of the flat extrusion cylinder. The upper insert piece and the lower insert piece are symmetrically disposed on an inner wall of the inner sleeve ring piece to form an inner sleeve working die cavity of the flat extrusion cylinder. Arc surfaces of two insert pieces match with the arc inner wall of the inner sleeve ring piece, so as to improve the stress distribution at interface portions between the flat surface and the arc surface of the inner sleeve working die cavity. When the flat extrusion cylinder is operated, the insert pieces will make a minor displacement in upward and downward direction due to the pressure from the inner sleeve working die cavity, such that the inner sleeve ring piece is elastically deformed in a circumferential direction, thereby generating a resisting force against the peak stress in the cylinder. In the flat extrusion cylinder according to the present invention, concentrated internal stress is uniformly transmitted to the inner sleeve ring piece, which decreases the peak stress in dangerous sections and achieves cylinder-type stress distribution in the flat extrusion cylinder. Thus, the stress received by the inner sleeve ring piece is distributed uniformly, thereby increasing the lifespan of the entire flat extrusion cylinder.
摘要翻译：用于扁平挤出圆筒的内套筒包括内套筒环件，上插件件和下插件件。内套环环件位于扁平挤压缸的中间套筒中。上部插入件和下部插入件对称地设置在内部套筒环件的内壁上，以形成扁平挤压缸的内部套筒工作模腔。两个插入件的圆弧表面与内套筒环件的弧形内壁相匹配，以改善内套筒工作模腔的平坦表面与圆弧表面之间的界面部分处的应力分布。当扁平挤压圆筒工作时，由于来自内套筒工作模腔的压力，插入件将在上下方向上产生较小的位移，使得内套筒环件在圆周方向上弹性变形，从而产生抵抗气缸中的峰值应力的抵抗力。在根据本发明的扁平挤出圆筒中，集中的内应力均匀地传递到内套筒环件，这降低了危险部分中的峰值应力，并在扁平挤出圆筒中实现了圆筒型应力分布。因此，内套筒环件接收的应力均匀分布，从而提高了整个扁平挤压圆筒的使用寿命。

摘要： Forging equipment and techniques prevent damage to the die set while also preventing abnormal flow of the material used in the forging process. In one embodiment, the forging equipment comprises a die set with a holding portion, constructed separate from the guiding portion. The holding portion is configured to accommodate the workpiece material and the punch portion as it is dropped down on the workpiece. At the comer where the holding portion and the guiding portion meet, the holding portion forms a retaining cavity, which has a sufficient size to accommodate a metal sealing assembly. The metal sealing assembly at one end terminates in an angled material contacting surface that prevents formation of cracks and abnormal flow of material away from its intended path of flow.

摘要： An arrangement for obtaining proper alignment of parts and proper sealing of parts in an extrusion press having an offset supporting shaft rotatably carrying a container holder assembly and two or more containers into which heated billets are placed to be brought to the extrusion station. A set of aligning keys diametrically opposite each other on both ends of each container engage with a corresponding set of keyways in a sealing member and a die slide respectively. Clearances provided between the containers and the container holder and between other keys and keyways used to mount the containers in the container holder allowing the containers to be moved in a direction to enable the sets of aligning keys to engage the keyways in the die slide and the sealing member to align the containers when in the extrusion station to other components of the press and to maintain these three elements in the aligned position with respect to the slide and sealing member, and in addition, the sealing member is guided on the same guideways as the main crosshead carrying the extrusion stem and mandrel.
