Analysis of possibilities for manufacturing of large-sized powder parts of cup type on extrusion press with actively directed contact friction stresses

摘要

Two options for manufacturing parts of the cup type from iron powders, which differ in the sequence of pressing operations of the billet and its sintering is compared. The possibility of combining both of these technology options in the one technological process is considered. According to the transitions of forming workpiece on the created press with force of 6.3 MN the implementation of such technological process for the production of part with mass of 4 kg 790 g is considered.
