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 press machine includes a controller including a displacement calculator being adapted to calculate a slide displacement with a slide being kept at a waiting position displaced from a top dead center by an amount corresponding to a predetermined crank angle based on a measured value of a pre-adjustment die height provided for a height adjustment of the slide, a desired value of a post-adjustment die height, the crank angle, a distance between an upper surface of a bolster and a crank center of an eccentric portion, a crank radius of the eccentric portion, and a distance between a lower surface of the slide and a point center, thereby associating the slide displacement with a difference between the pre-adjustment die height and the post-adjustment die height.

A slide motion control apparatus for a mechanical press comprising: a slide which is disposed so as to be relatively vertically movable with respect to a driven body to which a drive force is transmitted through a con rod of the mechanical press; a relative position commander that outputs a relative position command indicating a relative position of the slide with respect to the driven body; a relative position detector that detects a relative position of the slide with respect to the driven body, and outputs a relative position detecting signal indicating the detected relative position; a servomotor; a drive mechanism that relatively moves the slide with respect to the driven body by a drive force of the servomotor; and a controller that controls the servomotor based on a relative position command signal output from the relative position commander, and the relative position detecting signal output from the relative position detector.

A method and a press are proposed for an energy-efficient drive of a press (1) with a bottom drive, in which a drive device (2) disposed in a bottom section (3), a plunger (1.1) executing a stroke (H) and receiving an upper tool part (1.2) with at least one acting tie rod (2.1.2) of a drive train (2.1) are provided and the upper tool part (2.1) corresponding to a bottom tool part (3.2) disposed in the bottom section (3) machines or forms a work piece (5). The drive device (2) is operated by at least one motor (2.1.1) and by way of a control and regulation device (4) connecting the motor (2.1.1) and the drive train (2.1). Each drive train (2.1) can be operated by its own motor (2.1.1). When using a drawing device with a holder (3.3.1), it is operated in the change and during at least a partial path of the respective stroke (H) by the drive train (2.1) while observing a shaft-type free space (3.2) provided in the bottom section (3) in a coupled or decoupled manner by a releasable rotatory or translational active connection.

A forging machine with one or more hammers, comprising, for each hammer, an eccentric shaft (1) adapted to rotate about a first axis; a connecting rod (2), adapted to be actuated by the eccentric shaft operating as crank; a guiding frame (10); wherein the hammer is adapted to perform an alternating working movement within said guiding frame along a second axis perpendicular to the first axis; wherein the hammer comprises a hydraulic cylinder (8) provided with a hollow body (5), to which a forging member (15) is externally fixed, and with a piston (3) at least partially inserted within said hollow body and removably coupled to the connecting rod; wherein a first hydraulic chamber (6), arranged between piston and hollow body, allows to move the hollow body away from and/or towards said piston; wherein uncoupling means are provided for uncoupling the piston from the connecting rod.

A press with a press drive for moving a plunger in stroke direction (H). The press drive comprises two electric drive motors which are controllable independently of each other. The two drive motors are connected to the plunger via a drive unit. A control arrangement is provided for controlling the two drive motors. The control arrangement includes a characteristic plunger curve (K) which determines the plunger positions and/or the plunger movement and/or the plunger force dependent on time or dependent on a so-called virtual press angle. In addition, the control arrangement includes an additional condition which is independent of the characteristic plunger curve (K). Via the additional condition the operation of the press drive, for example, in an optimum operating range and/or a low-wear lubrication state of the support bearings of the drive unit can be ensured.
