ANORDNING TIL KONTINUERLIG FRIKSJONSDREVET EKSTRUDERING |
摘要 |
<p>In a modified "Conform" machine for continuous friction-actuated extrusion of metals, especially particulate copper, the abutment at the outlet end of the working passageway does not fully block the end of the wheel groove. Instead a substantial clearance is left, and metal extruding through it adheres to the wheel to re-enter the working passageway at the entry end. Preferably the abutment is of semicircular cross-section. For a given output rate, a significant reduction in torque, and working stresses, is obtained.</p> |
