Cable Presses for Charging of Liquid Metal

One of the first cable presses which was widely adopted both in Germany and in foreign countries, is the Huber Press, brought out in 1892 (Fig. 14) and named after its inventor, which continues to be in operation 

575-ton horizontal two-ram lead cable press, Huber system (By Krupp Grusonwerk, Magdeburg) 

The tooling is illustrated in Fig. 15 and consists of a die-block a and two rams h acting opposite to each other The rams force the lead through an annulus formed by the mandrel c and the die d. The lead pipe e thus being formed fits round the cable core, which is indicated by a dash-dot line, and draws it through the hollow mandrel. The sheathed cable core 

The press rests on its full length on a base frame. The tools are extraordinarily easily accessible and the cable enters at and emerges from the center of the press vertically to its longitudinal axis. A worm-driven rotating mechanism serves to release the screwed joints for mandrel and die when changing the tooling. 

The press was built in two sizes, the data of which are given in Table 2.
