| 摘要 |
A method for operating a mechanical press comprising an electric drive motor, a drive control means for controlling the motor, a ram, a flywheel (35), a clutch (30) and a member (27) for translating rotational motion of said flywheel in a first rotation direction into a linear motion of said ram (23) arranged to be lowered and raised along a linear path (S) for operating the press to carry out a press production cycle. The press cycle includes a pressing part and one or more non-pressing parts. The press comprises a second drive motor or actuator arranged connected to the ram and by providing a control output to said drive control means, the speed of said second drive motor is made variable during at least one part of a said press production cycle. The press may be reversed between production cycles. A press and system including a such press are also described.
