Abstract

687,937. Extruding. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and FRY, F. H. Jan. 4, 1951 [Oct. 5, 1949], No. 25617/49. Class 83 (iv). [Also in Group V] A press for extruding tubing such as electric cable sheathing, of metal or other material, has the die or hollow mandrel eccentrically mounted in a sleeve eccentrically mounted in the machine frame so that by rotation of the two parts the axes of the die and mandrel may be adjusted laterally to compensate for uneven pressures &c. and so maintain the inner and outer walls of the tube concentric. A cable is pulled through a hollow mandrel 1 in an extrusion press and covered with a fluid material from an annular space 2 surrounding the mandrel. The material is extruded on to he cable through an annular space 3 between the tip of the mandrel and the orifice of a die 4. The die holder 5 has a cylindrical peripheral surface which is eccentric to the die axis and is rotatable in a die holder ring 6. The external cylindrical surface of the ring 6 is eccentric with respect to its internal surface and is rotatable in a mounting unit 7 on the press frame. The die holder ring 6 and the die holder 5 are located axially by an annular shoulder 8 on the unit 7 and a sleeve 9. The die setting is adjusted by removing the sleeve 9 and rotating the die holder and the ring by inserting a tool in recesses (not shown). Alternatively, the holder and the ring may have sleeves with extending arms for making this adjustment. For forming tubing of non-circular cross section the die is arranged to turn with respect to the die holder so that, when the die axis is moved, the die may be retained in the same angular position about that axis.
