Abstract

La présente invention concerne un presse plieuse pour le pliage de feuilles métalliques (F) se caractérisant au moins un butoir est disposé dans chaque fente, chaque butoir comprenant une première cale (28) ayant une première extrémité solidaire du premier bord de fente et une deuxième extrémité formant une première surface et une deuxième cale (29) ayant une première extrémité solidaire du deuxième bord de fente et une deuxième extrémité formant une première surface, et en ce que la première surface d'au moins l'une des première (28) et deuxième (29) cales présente une portion centrale bombée ou protubérante (30 ou 31) par rapport aux autres portions de ladite surface de sorte que le contact entre la première (28) et la deuxième (29) cale s'effectue essentiellement sur cette portion centrale (30 ou 31).The present invention relates to a press brake for bending metal sheets (F) characterized at least one stopper is arranged in each slot, each stopper comprising a first wedge (28) having a first end integral with the first edge of the slot and a second end forming a first surface and a second wedge (29) having a first end integral with the second slot edge and a second end forming a first surface, and in that the first surface of at least one of the first (28) and second (29) shims has a domed or protruding central portion (30 or 31) relative to the other portions of said surface so that the contact between the first (28) and the second (29) shim takes place essentially on this central portion (30 or 31).
