Method for operating a press with sliding bearing lubrication as a function of the press operating state
Abstract:
A press, a method for operating the press, and a lubricating arrangement for the press or for another working machine. The press has a press drive that is connected with a ram of the press, which ram can be moved via a transmission in a working direction (Z). The transmission has at least one sliding bearing with one and, preferably, several lubricating points. In a first press operating state, all the lubricating points of the sliding bearing are supplied with lubricant at a first lubricant pressure (p1). In a second press operating state, the thickness of the lubricant film formed in the sliding bearing drops below a minimum value in the region of at least one first lubricating point and lubricant is supplied thereto at a second greater lubricating pressure (p2) in order to prevent increased wear of the sliding bearing.
