Abstract
A turret punch press (1) includes an upper turret (5) for holding punches (P) and a lower turret (7) for holding dies (D). The diameter of the lower turret (7) is larger than that of the upper turret (5) so that a punch exchange position (61) and a die exchange position (61), which are opposite to a punching position (21), are separated away from each other. This arrangement enables the die to be exchanged from above the same, expands the freedom of designing of dies, improves workability, and realizes an automatic die exchange in an automatic index station.
Claims18
A turret punch press comprising:
- an upper rotary turret for holding punches and a lower rotary turret for holding dies, the diameter of the lower turret being larger than that of the upper turret so that a punch exchange position and a die exchange position are separated away from each other.
A turret punch press comprising:
- an upper rotary turret for holding punches and a lower rotary turret for holding dies, the upper and lower turrets being horizontally movable to separate a punch exchange position away from a die exchange position, wherein at least one of the upper and lower turrets is rotatably mounted on a pivotal frame which is pivotally mounted on a shaft.
A turret punch press comprising:
- an upper rotatory turret for holding punches and a lower rotatory turret for holding dies, the upper and lower turrets being horizontally movable to separate a punch exchange position away from a die exchange position, wherein at least one of the upper and lower turrets is rotatably mounted on a slide base which is supported on a frame so as to be slidable along a linear axis.
