Abstract

938,521. Extruding. HYDRAULIK G.m.b.H. April 7, 1960 [May 13, 1959], No. 12477/60. Class 83 (4). An indirect extrusion method for producing elongated products 12, comprises extruding a billet from an axially moving container 7 through a die orifice in an extrusion plate 4 mounted on the end of a hollow extrusion stem 3, the plate 4 being so shaped that during extrusion residual metal 14 collects around its periphery and at the termination of extrusion the plate with the extrusion residue 13, 14 adhering thereto is pushed out of the rear end of the container, Fig. 4, whereupon the residue is separated from the extruded product. The stem 3 is secured to a stationary cross-beam 1 and the extrusion plate 4 is secured thereto by a threaded internal sleeve 6, Fig. 9 (not shown). The plate has an octagonal cross-section, Fig. 10 (not shown), whereby during extrusion in which the container 7 is moved to the right by a ram 10, residue metal from the billet surface is divided into strips 14, Fig. 4, which collect in an annular groove in the plate. After extrusion, the ram 10 with the residue 13, 14 adhering thereto is withdrawn and the extruded product is then severed by a saw 15. Finally a device 16, Fig. 6, removes the residue from the ram and a charging device 18 pushes a fresh billet into the container 7.
