The invention relates to a powder press (1) for producing a pressed article from a material that can be pressed, having a press frame (10), an upper and/or lower punch assembly (14) and a die assembly, which define a molding cavity, into which the material that can be pressed can be introduced, and an electric drive unit (12) which is operatively connected to the punch assemblies (14) and/or the die assembly, wherein, in order to mold the pressed article, the punch assemblies (14) and the die assembly can be moved relative to each other along a pressing axis (18) and pressed against each other by means of the electric drive unit (12). Furthermore, the operative connection between the electric drive unit (12) and one of the punch assemblies (14) comprises a toggle lever drive (16) which moves the punch assembly (14) into a pressing end position along the pressing axis (18).

A pressing apparatus 1 includes a storage 27 that stores a plurality of actual data which are load data which was actually measured and which are configured of a first information and a second information, and a plurality of reference data which is a reference for the load data, an adjustor 23 that expands and contracts the first information of at least one of an actual data pattern which is based on the plurality of the actual data stored in the storage 27 and an reference data pattern based on the plurality of the reference data stored in the storage 27 to correspond with each other, and a determiner 24 that determines appropriateness of a load applied to the ram 9 in a pressing operation based on a similarity of the actual data pattern adjusted by the adjustor 23 and the reference data pattern adjusted by the adjustor 23.

A press brake includes a ram to which an upper or lower tool can be attached; a movable ram driver; and a controller that controls the ram driver, wherein the ram driver includes a rotation/linear motion converter composed of a screw fixed to the ram and moves upward and downward as the ram moves upward and downward, and a nut screw-coupled with the screw; a drive rotation body arranged rotatably about a rotation axis of the nut; a first motor arranged in a fixed state; a first power transmitter that transmits rotation of the first motor to the nut at high speed and with low torque; a second motor arranged in a fixed state; a second power transmitter that transmits rotation of the second motor to the drive rotation body at low speed and with high torque; and a clutch provided between the nut and the drive rotation body.

A pressing device for pressing meat products, in particular frozen and/or partly frozen meat products, preferably fresh meat products and/or bacon, comprises a pressing chamber which extends along a longitudinal axis and into which a product to be pressed can be inserted, wherein the pressing chamber comprises at least one counter-element and at least one contact element, which is movable in the direction of the counter-element, that cooperate such that the product inserted into the pressing chamber can be compressed between the at least one counter-element and the at least one contact element; and wherein the pressing device comprises at least one servomotor that is configured to move the at least one contact element.

In a method of pressing and processing meat products, in particular frozen and/or partly frozen meat products, preferably fresh meat products and/or bacon, the products are inserted into a pressing chamber of a pressing device and are pressed in the pressing chamber by at least one displaceable contact element, with the contact element being moved by means of a servomotor.

A multi-axis motor control system includes a host control apparatus, motors, motor control apparatuses that drives the motors and each includes circuitry that acquires control related information transmitted and received between the host control apparatus and at least one other motor control apparatus, and controls a corresponding motor of the motors based on the control related information, and a communication channel that connects the host control apparatus and the motor control apparatuses in series.

Disclosed is a double-motor double-station screw press, comprising two sets of screw pair mechanisms on both sides thereof, i.e., first and second screw pair mechanisms, where in the first screw pair mechanism, a first lead screw is driven by a resultant movement synthesized by first and second motors through a first differential gear train; in the second screw pair mechanism, a second lead screw is driven by a resultant movement synthesized by the first and second motors through a second differential gear train; a first slider and a second slider in the press work symmetrically; a transmission mode between the second motor and the second differential gear train is switched by controlling a steering switching apparatus, such that the second motor can assist the first motor during a single-cylinder pressing process to increase the output pressure, but also it is convenient to adjust a relative positions of two cylinders.

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.
