Abstract

PURPOSE:To realize the prevention of a material leakage, while suppressing the equipment from becoming a large size by providing a pressing means for sealing the part between a container and an extruding tool by utilizing excess force of a main ram. CONSTITUTION:A billet B is loaded in a container 1, and when a main cylinder 6 is operated and a pushing ram 4 advances, the billet B is allowed to pass through an extruding tool 2, and an extruded material A of a prescribed cross section shape is formed. At the time point when length of the billet becomes short to some extent, a cylinder 10 contained in a crosshead 7 is operated, extrusion of the rear face of a container tire 1a is started by a rod 10a, and seal force between the container 1 and the extruding tool 2 is reinforced. In such a way, in all the extrusion processes extending from the start to the ending of extrusion, the material leakage can be prevented.

[Prior art and problems] In extrusion processing, a container is held pressed against the rear surface of an extrusion tool including a die, etc., and the billet metal inside the container is pressurized from behind by a pushing ram to pass through the die forming hole. Conventionally, when the pushing ram advances and the billet is pushed a certain distance, billet metal sometimes leaks from between the extrusion tool and the container, so-called material leakage.

The reason for this is that the sealing force between the extrusion tool and the container has conventionally been reduced by a force F1 that presses the container toward the extrusion tool by a cylinder device for advancing and retracting the container, which is provided on the platen and connected to the container. and the frictional force F2 between the billet metal and the inner surface of the container. Therefore, when the length of the billet inside the container becomes shorter than a certain level during the extrusion process, the frictional force F2 between the billet metal and the inner surface of the container decreases. This is because the resultant force of the pressing force F1 by the cylinder and the frictional force F2 falls below the sealing force necessary to prevent material leakage.

[0004] Such material leakage reduces the manufacturing yield of the mold material, and also requires work to remove the slag accumulated between the extrusion tool and the container after each cycle of extrusion. This causes problems such as lowering the operating rate of the machine and reducing the productivity of the mold material.

[0005] As a solution to this problem, it is possible to increase the power of the cylinder device for moving the container forward and backward. However, in that case, the size of the cylinder device will increase, and the size of the container housing will increase accordingly. As a result, the extrusion processing equipment becomes larger and its cost increases, and other disadvantages arise.

[Operation] In the extrusion processing apparatus configured as described above, during one cycle of extrusion process, for example, when the length of the billet becomes shorter than a predetermined length, the pressing means starts pressing the container. A sealing force is applied between the container and the extrusion tool by the pressing force of the pressing means, and leakage of the billet metal is avoided. In this case, since the frictional force between the billet and the inner surface of the container has decreased at the time when the pressing means starts pressing, the total force of the frictional force and the deformation force of the billet metal, that is, the force required for extrusion, is low. The surplus force of the main ram resulting from this is used as a force for pressing the container by the pressing means.
