A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

A sheet material bending system includes a tool changing apparatus that changes tools between a press brake and a tool stocker. The tool stocker is arranged behind the press brake. To change tools from the front and rear of the tool stocker, the front and rear of the tool stocker are opened. The tool changing apparatus has a pivot that is movable in front-rear, left-right, and up-down directions and is rotatable around an axis extending in the up-down direction. A front end of the pivot is provided with tool holding units to hold tools.

A rotary press comprises a press frame and a rotor arranged thereon. The rotor has a die plate, an upper punch receiver receiving upper punches, a lower punch receiver receiving lower punches, an upper cam that guides the upper punches, and a lower cam that guides the lower punches. A rotor drive can drive the rotor rotationally. Within at least one dosing station, material is filled into receivers of the die plate for pressing. An upper pressing station has an upper pressing roller and a lower pressing station has a lower pressing roller. Coupling means couples at least one drive that operates the rotary press to the rotor such that, with movement of the at least one drive, the rotor is raised out of its operating position and into a removal position where the rotor can be removed out of the press frame in a lateral direction.

Modular die set includes upper die shoe; lower die shoe, which has a first length, width, and thickness, and which is provided with an opening spanning a substantial, extensive portion of the first length and width of the lower die shoe, such that material can pass freely through the opening the first thickness of the lower die shoe and pass through the lower die shoe; and set of plural movable supports, which can be closely spaced or spaced apart in relation to one another, which can be selected and stationed to support a tooling subassembly and avoid any hole(s) in a lower tooling plate of the tooling subassembly such that scrap and/or parts to fall through the hole(s) can fall through the opening of the lower die shoe. The modular die can be mounted within a press, and parts made therewith.

A press molding apparatus (2) may include pairs of upper and lower dies (50, 52, 54, 56, 58, and 60) arranged in series in a same direction as a die-closing/die-opening direction. Each lower die (52, 56, 60) may be slidable via a bearing (42e) to a position deviated from a die-closing/die-opening position with respect to a plate (42, 44, 46) to which the lower dire is fixed in position. The bearing (42e) inserted into each plate (42, 44, 46) via a compression spring (42d).

The invention relates to a handling apparatus for handling a roller of a roller crusher. The handling apparatus comprises a movable base, a carrier pivotably attached to said base and adapted to carry the roller, at least one carrier pivoting device pivotably attached to said base and attached to said carrier, said carrier pivoting device being extendable, and at least one roller pivoting device pivotably connected to said base, said roller pivoting device being adapted to releasably engage said roller. The invention also relates to a method for mounting a roller to a roller crusher and a method for dismounting a roller to a roller crusher.

A tablet-pressing apparatus comprising i) a hopper (10), ii) a tablet-pressing table (20) in which there is provided a die (30) for containing material that is to be pressed into a tablet, and iii) a punch (40) for pressing material in the die (30) to form a tablet is described. The components (10, 24, 30, 40, 42, 50) of the apparatus that come into contact with the material or the tablets may be disposable and thus readily replaced at low-cost. For example, the table (20) may comprise a removable top plate (24) so that after the tablet-pressing apparatus has been used to produce a batch of tablets, the top plate (24) may be disposed of and replaced with a fresh top plate. The apparatus may then be used to press a batch of tablets of a different composition without needing to clean the top of the table (20).
