摘要： A method for operating an elastically mounted forming machine which is path-bound or force-dependent, in which method a working stroke of a ram device operatively connected to the drive is initiated by means of a drive, and a predefined forming process is carried out on a workpiece by moving the ram device during said working stroke, in particular due to the interaction of an upper tool located on the ram device with a lower tool located on a tool table, wherein the inertial forces and/or moments of inertia occurring during operation owing to the initiation of the working stroke and/or owing to an imbalance in the drive are at least partially compensated. The method, wherein at least one kinematic variable (s(t),v(t),a(t)) of a rigid body motion of the elastically mounted forming machine is detected during the operation thereof, wherein the time at which the working stroke is initiated is adapted to an instantaneous phase position of the at least one kinematic variable (s(t),v(t),a(t)) of the rigid body motion in order to generate inertial forces and/or moments of inertia so as to counteract the rigid body motion of the forming machine.

摘要： A servo press machine includes a display unit that displays a strip-shaped region for setting a motion of a slide and an operation unit that receives an input operation. A range extending from an upper end of the strip-shaped region to a lower end thereof corresponds to a movement range of the slide in a linear movement, and the strip-shaped region is formed of a plurality of slide operation regions that are consecutive in a direction in which the strip-shaped region extends. Each of the slide operation regions can set a speed of the slide in response to the input operation received by the operation unit, and a boundary between adjacent two of slide operation regions can move along the direction in which the strip-shaped region extends in response to the input operation received by the operation unit.

摘要： A dynamic balance device for a press machine includes a plurality of cam portions which transmit a vertical motion of a slide to a balance weight to move the balance weight in a reverse direction of the vertical motion of the slide. The cam portions are each movable in a direction substantially orthogonal to a moving direction of the slide, and each include a first inclined surface and a second inclined surface. The first inclined surface has an inclination angle corresponding to an inclination angle of an inclined surface formed on a member which is provided integrally with the slide and vertically moves with the slide. The second inclined surface has an inclination angle corresponding to an inclination angle of an inclined surface formed on the balance weight.

摘要： The invention relates to a press drive for a press or a press having a press drive. The invention also relates to a method for controlling the press drive by means of a control unit. The press drive is used for moving a ram of the press in a stroke direction H between an upper return point OT and a lower return point UT. It comprises a knee lever gear having a first lever and a second lever. A connecting rod engages on the knee lever of the two levers and is connected on the other end to an eccentric of an eccentric drive. The control unit can drive the eccentric drive in a first operating mode B1 or a second operating mode B2 or, in particular, also a third operating mode B3. In the first and the second operating modes B1, B2, the eccentric oscillates in a respectively different angle region W1, W2 about a rotation axis D of the eccentric drive, thus resulting in different force and movement states of the ram in both operating modes.

摘要： A press system for knocking out a work from a lower die attached to a press machine has a cam 22 mounted on a bed of the press machine; a servo motor 21 which drives the cam to be rotated with the same cycle time as that of a drive mechanism of a slide of the press machine; a knockout pin 23 moved with reciprocal linear motion by the rotation of the cam; a detector 25 configured to detect a present angle information 24 of the cam, a memory storing a target angle information of the cam, and a controller 28 configured to control the servo motor in accordance with the present angle information and the target angle information. The controller is further configured to change a basic motion of the knockout pin according to contour of the cam to a target motion obtained from the target angle information.
