Abstract
358,379. Making tubes. E V A N S, C. O., Truell Court, Plainfield, New Jersey, U.S.A. Dec. 31, 1930, No. 39298. Convention date, March 5. [Classes 83 (i), 83 (ii), and 83 (iv).] Squirting; casting-machines ; castings, extracting.-Billets are cast in the container of an extrusion press for tubes around a central member which is withdrawn on cooling to form a central passage for a mandrel. A press comprises a die 1, capable of small axial displacement, a container 4, and a ram 2 with an axially movable central mandrel 3. The container is retained by a hydraulically operated latch pin in the working position between upper and lower grooved members, the lower guide being extended on both sides in the form of rails 9 along which two containers may alternately be moved into working position by pistonrods 18. A container may be withdrawn for charging to a cradle 10 carried in a frame on segmental gear members 14 rotatable manually or by power from engaging pinions through 90‹. A core member 20 is raised hydraulically and the molten metal poured in, the member 20 being again withdrawn on cooling. After again rotating the cradle through 90‹, the container is returned to its original position and the mandrel 3 and then the ram 2 are advanced axially for the extrusion process.
