A tool holder for a punching machine, comprising several punching units (14)
that are accommodated in tool holding fixtures (12) in the holder (10) in
addition to gas pressure springs (15) to recall the punches (20). The
advantage of gas pressure springs is that the pressure level can be adapted to
the material that is to be machined. In order to make it easier and quicker to
achieve said adaptation, the pressure chambers (28, 32) of the gas pressure
springs are joined to a common supply line (44) which can be connected to a
pressure gas source. As a result, it is possible to change the internal
pressure of all the gas pressure springs (15) at the same time.
L'invention concerne un porte-outils destiné à une presse à découper, qui comporte plusieurs unités à poinçon (14) qui sont logées dans des logements d'outil (12) du support (10) et présentent des ressorts à pression de gaz (15) pour le rappel des poinçons (20). L'avantage offert par les ressorts à pression de gaz réside dans la possibilité d'adaptation du niveau de pression à un matériau à travailler. Pour obtenir, avec des supports multiples, une adaptation plus rapide et plus simple, il est proposé que les chambres de pression (28, 32) des ressorts à pression de gaz (15) soient raccordées à une conduite d'alimentation (44) commune pouvant être reliée à une source de gaz sous pression. On obtient ainsi la possibilité de modifier simultanément la pression intérieure de tous les ressorts à pression de gaz (15).
