Tool for stamping pneumatic actuator to press sheet e.g. side of body of car, has closing unit sealing cell such that cell is adapted to form reserve to store compressed air for pneumatic actuator

摘要

The tool (10) has a honeycomb structure (12) for delimiting a parallelepipedic cell (20), where the structure of the tool is molded by casting in a single-piece. A closing unit (28) seals the cell such that the cell is adapted to form a reserve (22) to store compressed air for a pneumatic actuator. The structure comprises multiple buttresses (18), where each buttress is extended from a lower edge connected on a wall of the structure, to an upper edge that cooperates with the closing unit. The closing unit comprises a lid (26) that cooperates with the cell.
