PURPOSE:To highly keep working accuracy by providing main gears which are transferred and revolved about the axes of turret, a die gear which receives each die and which is revolved, an intermadiate gear with which revolution is transferred from the main gears to each die gear and a switching clutch for turret with which transferred revolution is inputed. CONSTITUTION:The main gears 49, 51 are transferred and revolved about the axes 29, 33 of turret by driving a motor. When the turret is made to revolve, the turret is revolved by turning switching clutches 85, 87 for turret to 'on' and an objective die is selectively positioned in the punch center P. And, when the direction or angle, etc. of die is made to index, the turret isn't revolved by turning those switching clutches 85, 87 for turret to 'off'. The posture of the punch press on the punch center is indexed by transferring and revolving the die gear 73 through the main gear 51 and the intermediate gear 61 and revolving dies which are received with that die gear 73 in the objective direction. By this way, the transmission process for driving power is simplified and high working accuracy can be kept. |
