Abstract

334,159. Hydraulik, Ges., and Schlenstedt, O. Feb. 11, 1929, [Convention date]. Squirting ; billet-piercing.-In squirting tubes a billet 14 and die 19 are placed in one end of a fixed container 1 in the other end of which a closure 4 carrying a mandrel 15 is secured by a wedge 6. A hollow mm 7 is then advanced by one or more cylinders 10 to force in the die 19 and first piece and then extrude the billet 14. After extrusion the closure 4 is removed by a handle 18 or by a mechanical or hydraulic device and further advance of the ram 7 enables the unextruded residue to be removed. In a modification the mandrel 15, Fig. 2, has a limited movement relative to the closure so that friction between it and the work is reduced during extrusion. In another modification the mandrel 15, Fig. 5, can also be removed from the closure, by withdrawing a fork 17 or other stop, so that it can be replaced by a cold mandrel.
