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.

Dependent claims

Punching apparatus comprising a beating element (2) arranged for interacting with at least one punching tool (30) and movable inside a containing means (3) along and around a work axis (A), a first rotating actuator (4) coupled by transmission means (10) to said ram (2) for moving the latter linearly along said work axis (A) between an internal operating position (R) and an external operating position (T) and driving said punching tool (30), a second rotating actuator (5) connected to said beating element (2) and arranged for rotating the latter around said work axis (A), in particular to for angularly orienting said punching tool (30), characterized in that said second rotating actuator comprises a second electric motor (5) provided with a stator (51) fixed to said containing means (3) and a rotor (52) that is internal and coaxial with said stator (51) and connected to said beating element (2) in such a way as to rotate with the latter, said rotor (52) extending along said work axis (A) in such a way as to face, and be engaged with, said stator (51) between said operating positions (R, T) to rotate around said work axis (A) when said second electric motor (5) is operated.

Punching apparatus comprising:

a beating element (2) arranged for interacting with a punching tool (30) and movable inside a containing means (3) along and around a work axis (A);
a first rotating actuator (4) coupled by transmission means (10) to said beating element (2) for moving the latter linearly along said work axis (A) between an internal operating position (R) and an external operating position (T) and driving said punching tool (30);
a second rotating actuator (5) coupled to said beating element (2) and arranged for rotating the latter around said work axis (A);
at least one tool holding unit (20) that is fixed to said containing means (3) rotatable around a respective rotation axis (B) and provided with at least one seat (21) suitable for slidably housing a respective punching tool (30);
said apparatus (1) being characterized in that said beating element (2) comprises an operative end (8) provided with coupling means (9) arranged for coupling with further coupling means (22) of said tool holding unit (20) so as to rotate the latter around the respective rotation axis (B) and enable said punching tool (30) to be angularly oriented.
