摘要： A method is used to manufacture a tube having a hollow interior for housing an axle shaft. The tube is formed in a single machine having a fixed base and a single press structure movable toward the fixed base. The single machine includes first and second die assemblies coupled to the fixed base and first and second mandrels coupled to the single press structure. The method includes the steps of placing a billet into the first die assembly, pressing the billet into the first die assembly with the first mandrel to producing a pre-formed billet, and moving the pre-formed billet from the first die assembly to the second die assembly. THE method further includes the steps of pressing the pre-formed billet into the second die assembly with the second mandrel to elongate the pre-formed billet and form a hollow interior therein to produce an extruded tube.

摘要： A method is used to manufacture an article using a machine having a fixed base and a press structure movable toward the fixed base. The machine also includes a die assembly and a container both coupled to the fixed base. The machine further includes a mandrel assembly comprising a rotatable platform coupled to the press structure and having a first platform mandrel aligned with the die assembly and a second platform mandrel aligned with the container. The method includes the steps of placing a first starting component into the die assembly, pressing the first starting component to form the article, moving the second platform mandrel into the container simultaneously with the step of pressing the first starting component, and rotating the rotatable platform to align the second platform mandrel with the die assembly and to align the first platform mandrel with the container.

摘要： A method for producing a metal cylinder includes preparing a metal slug having a surface adjusted so that the crystal grain diameter at a depth of 10 μm from the surface is smaller than that at a depth of 100 μm from the surface, and the crystal grain diameter at a depth of 10 μm from the surface is 30 μm or more and 120 μm or less; and forming a cylinder by impact pressing of the metal slug having the surface as a bottom.

摘要： A method and apparatus in a hot multi-stand tube mill for producing a thin metallic tube having end portions which corresponds to the wall thickness and diameter of the rest of the rolled tube or alternately, tapered ends. Each stand is provided with a set of three cooperating rolls arranged to form a roll pass opening. According to the tube's positioning in the mill, an appropriate additional adjustment of the rolls to decrease or enlarge the roll pass diameter is made in one or all of the last three stands. Both an initial roll setting varying means and an additional roll setting varying means cause movement of wedges abutting the roll chocks thereby causing movement of the rolls.
