Disclosed herein are an electric press and a method for calibrating the electric press, which can implement a rapid calibration operation. An electric press (10) includes a ram location information storage unit (63) and a load control unit (64). The ram location information storage unit (63) stores ram location information, corresponding to actual load values and representing locations to which a ram is moved, in advance. The load control unit (64) applies an actual load, corresponding to at least one location which belongs to the locations represented by the ram location information and to which the ram is moved, to a compression target by moving the ram to the location. Accordingly, the load value output by the detection unit is calibrated based on the actual load value applied to the compression target.

A press machine is provided. Two vertical hydraulic cylinders are arranged on an upper beam plate of a press machine body, and the two hydraulic cylinders correspond to workbenches at corresponding positions in a one-to-one correspondence, constituting left and right working units, and a common mechanical drive unit and a common hydraulic drive unit are set for the left and right working units. The mechanical driving unit is composed of a driving motor through an electromagnetic clutch, an electromagnetic brake and lead screw nut driving mechanism driven by a gear pair. According to the load profiles during the working process of hydraulic press machine, the mechanical driving unit or the hydraulic driving unit are selected to provide energy for the two working units. A control method for the press machine, a press machine execution system and a control method for the press machine execution system are further involved.

Disclosed herein is a press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors configured to provide a first output signal indicative of deformation of the first sensing part. The method can be configured for determining if an error criterion based on the first output signal from the first displacement sensor has been met, and providing a control signal indicative of an error to the press-working apparatus if the error criterion is met.

A control device, a system and methods for optimizing and providing movement profiles, wherein the movement profiles serve for determining the movement of tools of a press and the movement of a receiving element for a workpiece of a transfer system, where transfer movement profiles are synchronized with one another via press movement profiles, the synchronization of the transfer movement profiles particularly occurs by chronologically shifting synchronization points via boundary conditions such that an offset of the press movement profiles can be determined via the synchronization, so that the workpiece can be processed as quickly as possible through the system.

A press device includes a slide, a bolster disposed below the slide, a servomotor configured to drive the slide, a power storage unit, a current detector, and a control unit. An upper die can be mounted on the slide. A lower die can be placed on the bolster. The power storage unit is configured to be able to supply stored power to the servomotor. The current detector detects current supplied from the power storage unit. The control unit performs stop control to stop supply of current from the power storage unit to the servomotor based on a detection value of the current detector.
