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.

A tablet discharge gate for a tablet press comprises a tablet channel having an inlet and an outlet and comprising one of a tube shape and a trough shape, a first outlet channel, and a second outlet channel. A gate chamber is positioned between the outlet of the tablet channel and the first and second outlet channels. A drive apparatus is configured to move the tablet discharge gate between a first position in which tablets are supplied from the tablet channel to the gate chamber and into the first outlet channel of the gate, and a second position in which tablets are supplied to the tablet discharge gate chamber and into the second outlet channel.

A baler is provided that includes a housing that defines a baling chamber and a plunger movable along an axis within the baling chamber to compress the crop material. The baler includes a first guide rail coupled to an exterior surface of the baling chamber and a second guide rail coupled to the exterior surface of the baling chamber. The baler includes at least one bearing coupled to the plunger to guide a movement of the plunger within the baling chamber. The bearing has a first bearing surface, a second bearing surface and a third bearing surface. The first bearing surface engages the first guide rail, the second bearing surface engages the first guide rail and the third bearing surface engages the second guide rail to constrain a vertical movement and a lateral movement of the plunger relative to the baling chamber.

A method of performing pressing on a workpiece using a press machine. The pressing method includes: performing pressing on the workpiece between a lower die and an upper die by causing the upper die to approach the lower die by using the hydraulic cylinder in a state in which the workpiece is disposed between the lower die and the upper die, and performing the pressing on the workpiece between the lower die and the upper die, in a state in which a shape of each of the frame, the lower die and the upper die has a rotationally symmetric shape about the reference axis and in which the workpiece center axis coincides with the reference axis.

A heat press device is provided that includes a support structure, a first platen and a heating element assembly that includes a heating element and a second platen. The heat press device further includes a movement assembly configured to change a pressure state between the first platen and the second platen when the heat press device is in a closed configuration. The heat press device can also include an indicator that is configured to convey the pressure state between the first platen and the second platen when the heat press device is in the closed configuration.

A press frame assembly includes a base plate, a load cell, and an overload protection element; a first plate, a plurality of guideposts disposed on the base plate; a plurality of springs disposed on the plurality of guideposts, a displacement transducer arranged to monitor a linear displacement of the first plate, and a controller, in communication with the load cell and the displacement transducer. The first plate is disposed to translate on the plurality of guideposts, and wherein the springs are disposed to urge movement of the first plate in relation to the base plate. The load cell is arranged to monitor a load exerted upon the base plate. The controller generates a signal that is based upon the load exerted upon the base plate or the linear displacement of the first plate in relation to the base plate.

A housing of a radial press has a casing section and an annular end-face support disc. An annular structure is movably guided in the housing along a press axis, and multiple press jaws arranged about the press axis are supported on the support disc so as to be movably guided in the radial direction. The annular structure acts on the press jaws by means of control surfaces which are inclined relative to the press axis and which lie against press jaw counter surfaces designed in the form of sliding surfaces. The end face of the ring structure facing the support disc is designed with axial protrusions. Each control surface protrudes into the radial inner surface of one such protrusion, and the support disc has recesses which are paired with the protrusions and into which the protrusions enter when the radial press is closed.
