Abstract
A punching apparatus includes a beating element that is arranged for interacting with at least one punching tool and is movable inside a container along and around a work axis, a first rotating actuator coupled to the beating element to move it linearly along the work axis between internal and external operating positions and drive the punching tool, and a second rotating actuator connected to the beating element and arranged for rotating it around the work axis, in particular for angularly orienting the punching tool. The second rotating actuator comprises a second electric motor having a stator fixed to the container and a rotor that is internal to the stator and connected to the beating element to rotate it. The rotor extends along the work axis to face, and be engaged with, the stator between the operating positions.
Claims13
A punching apparatus comprising:
- a containing element;
- at least one punching tool;
- a transmission system;
- a beating element that is arranged for interacting with said punching tool and is movable inside said containing element along and about a work axis;
- a first rotating actuator that is coupled by said transmission system to said beating element for moving said beating element linearly along the work axis between an internal operating position and an external operating position and driving said punching tool;
- a second rotating actuator that is coupled to said beating element and arranged for rotating said beating element about the work axis;
- and
- at least one tool holding unit that is fixed to said containing element, is rotatable about a respective rotation axis, and comprises at least one seat for slidably housing said punching tool,
- wherein said beating element is rotatably connected to said transmission system and comprises an operative end provided with coupling elements,
- wherein said tool holding unit further comprises further coupling elements, and
- wherein said coupling elements are arranged for coupling with said further coupling elements so as to rotate said tool holding unit about the respective rotation axis and enable said punching tool to be angularly oriented.
The apparatus according to 1, further comprising a tool holding turret that is connected to, and supported by, said containing element, wherein
- said at least one tool holding unit is a plurality of tool holding units, and
- said tool holding turret supports said plurality of tool holding units that are arranged angularly spaced and mounted on said tool holding turret and rotatable about respective rotation axes.
