摘要:
A round die type form rolling apparatus comprises: a pair of die moving blocks 15a, 15b rotatably supporting a pair of round dies 12a, 12b; four beam shafts 19 disposed around the rolling position of a work 33 being rolled by the round dies 12a, 12b and extending between the pair of die moving blocks 15a, 15b; and a push mechanism 20 for moving the pair of die moving blocks 15a, 15b toward each other. The die moving blocks 15a, 15b are moved, guided by the beam shafts 19, toward each other and the reaction forces generated between a pair of the round dies 12a, 12b by the rolling pressure are shared by the beam shafts 19 to prevent the round dies from escaping outwardly upwardly due to the reaction force from the work that is generated when the rolling pressure is applied to the work. This arrangement improves the machining precision of the work.
