| Title of Invention | CONTINUOUS EXTRUSION APPARATUS |
|---|---|
| Abstract | Continuous extrusion apparatus for the production of copper tubing having a rotatable wheel formed with a plurality of circumferential grooves registering with (as shown in the figure) abutments (4) formed on a die top (2). Respective exit apertures (6) each have a cross-sectional area of between two and five times the radial cross-section of the associated groove and lead to a passage (8) smoothly diverging to connect into an extrusion die chamber (10) housing an annular extrusion die (not shown). The apparatus produces an extrudate in the form of a continuous, seamless, copper tube having a mass in excess of 500 kilograms extruded at a temperature of approximately 750 degrees Celsius. |
