Beschreibung
Zusammenfassung:	The utility model provides a bidirectional chamfering die. The bidirectional chamfering die comprises an inner die, an outer die, an inner extrusion head, an outer extrusion head, an upper actuating mechanism and a lower actuating mechanism, the inner extrusion head is telescopically inserted into an inner guide hole in the inner die and faces the inner side opening edge of a spoke air hole; the lower executing mechanism is used for forcing the inner extrusion head to slide and extrude the inner side opening edge of the air hole, and then chamfering treatment is conducted on the inner side opening edge of the air hole. The outer extrusion head is telescopically inserted into an outer guide hole in the outer die and faces the outer side opening edge of a spoke air hole; the upper executing mechanism is used for forcing the outer extrusion head to slide and extrude the outer side opening edge of the air hole, and then chamfering treatment is conducted on the outer side opening edge of the air hole.
