<P>PROBLEM TO BE SOLVED: To provide a press device which can achieve energy saving. <P>SOLUTION: In the waiting state of a press working operation, when the detected temperature by a lubricating oil temperature detecting means is equal to or less than a first temperature t1, a controlling means holds a heating means 48 in a working state. When the detected temperature by the lubricating oil temperature detecting means is equal to or more than a second temperature t2 higher than the first temperature t1, the controlling means holds a cooling means 46 in the working state. Further, when the detected temperature by the lubricating oil temperature detecting means lies between the first temperature t1 and the second temperature t2, the controlling means holds both the cooling means 46 and the heating means 48 in a working halt state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
