    • PURPOSE:To set easily a rotary angle position in case of installing a titled die by cutting and forming a reference surface on the outside circumferential surface of a mandrel and a die, in the titled die constituted of the mandrel and the die. CONSTITUTION:A mandrel reference surface 10 and a die reference surface 11 which are cut and formed vertically from the outside circumference of a mandrel 1 and a die 2 of an Al extruding die are provided on said respective outside circumferential surfaces. The surfaces 10, 11 are based on mandrel and die bearing surfaces 6, 7 for constituting a bearing part 5, and are formed, for instance, in parallel to them. As a result, a relative relation of the surface 10 or 11, and the bearing part 5 becomes clear, and when the Al extruding die is installed basing on the surfaces 10, 11, its rotary angle position can be set easily to a desired angle position. Accordingly, there is no possibility that the Al extruding die material having a sectional shape corresponding to a shape of the bearing part 5 is deformed.
    • 目的:在由心轴和模具构成的标称模具中,通过在心轴和模具的外周面上切割并形成参考表面来安装标称模具的情况下,容易地设置旋转角度位置。 构成:在所述各个外周面上设置有从心轴1的外周和铝挤压模具的模具2垂直切割并形成的心轴参考面10和模具基准面11。 表面10,11基于用于构成轴承部分5的心轴和模具支承表面6,7,并且例如与它们平行地形成。 结果,表面10或11与轴承部5的相对关系变得清楚,并且当Al挤压模安装在表面10,11上时,其旋转角度位置可以容易地设定到期望的角度 位置。 因此,具有与轴承部5的形状对应的截面形状的Al挤出模具材料不可能变形。

    • PROBLEM TO BE SOLVED: To provide an extrusion die for metallic materials by which a high quality extruded article having excellent durability can be obtained.
      SOLUTION: The die is provided with: a die case which is disposed backward so as to make the pressure receiving surface of the metallic material of a pressure receiving part 21 face the extrusion direction; and a male die and a female die which are provided in the die case. The pressure receiving part 21 is formed so as to project backward and also portholes 24 for introducing the metallic material are provided to the outer periphery of the pressure receiving part 21. The ratio of the flat state area Sb of the portholes 24 to the flat state area Sa of the pressure receiving part 21 is set to 0.15 to 0.80. The die is constituted so that the metallic material pressurized by the pressure receiving surface of the metallic material is introduced into the die case through the portholes 24 and passed through the extrusion hole.
