Abstract: The present invention relates to an upsetting press (1, 1′) for upsetting an end (2) of a metallic material pipe (3), e.g. for petroleum applications. The press (1, 1′) comprises a supporting structure (10) which defines a working space and first locking means (15) for locking the pipe (3) to be upset. The press further comprises first upsetting means comprising at least one first upsetting die formed by a first pair of half dies (21, 22) which can be separated and closed about the end (2) of the pipe (3) to be upset and at least one axially movable cylindrical punch (30). The press (1, 1′) further comprises die holding means which support the half dies (21, 22) moving them between a closing position and an opening position. According to the invention, the die holding means are independent from said supporting structure and are transversally movable (102) between an operating position in which the half dies (21, 22) can be closed about the end (2) of the pipe (3) to be upset and at least a non-operating position such that the half dies can be washed and/or lubricated outside the working space of the press.

Abstract translation: 本发明涉及一种用于镦锻金属材料管（3）的端部（2）的镦锻机（1,1'），例如， 用于石油应用。 压力机（1,1'）包括限定工作空间的支撑结构（10）和用于锁定管道（3）以使其发生镦锻的第一锁定装置（15）。 压力机还包括第一镦锻装置，其包括由第一对半模（21,22）形成的至少一个第一镦锻模，所述第一镦锻模可围绕所述管（3）的端部（2）分离和闭合， 至少一个可轴向移动的圆柱形冲头（30）。 压力机（1,1'）还包括模具保持装置，其支撑在关闭位置和打开位置之间移动它们的半模具（21,22）。 根据本发明，模具保持装置独立于所述支撑结构，并且在半模（21,22）可围绕管（3）的端部（2）关闭的操作位置之间可横向移动（102） ）至少是非操作位置，使得半模可以在压机的工作空间之外被洗涤和/或润滑。
