Abstract

L'invention concerne une presse plieuse permettant d'effectuer une flexion d'une pièce (W) dans une attitude stable et de maintenir de manière stable la précision de traitement de la flexion. Dans un dispositif de commutation par le pied (29) de la presse plieuse, un boîtier de pédale (45) est conçu pour pouvoir pivoter dans une direction verticale par rapport à un élément coulissant (37) et comprend une partie butée (55) entrant en contact avec une surface de sol (F). Des roulettes (67) disposées de façon mobile dans la direction verticale sur les deux côtés dans la direction de la longueur du boîtier de pédale (45) sont poussées au moyen d'un ressort hélicoïdal (71) dans une direction vers le bas par rapport au boîtier de pédale (45). Le dispositif de commutation par le pied (29) est conçu de telle sorte que, lorsqu'une pédale d'abaissement (57) ou une pédale d'élévation (59) est enfoncée, les roulettes (67) s'élèvent par rapport au boîtier de pédale (45) contre la force de poussée du ressort hélicoïdal (71), et la partie butée (55) du boîtier de pédale (45) entre en contact avec la surface de sol (F).
