The double blank detecting device for a press machine uses a press machine with a die cushion device attached thereto, and automatically and repeatedly forms blank materials one by one. The double blank detecting device includes: a position signal acquiring unit that acquires a die cushion position signal indicating a position of a cushion pad of the die cushion device; a load signal acquiring unit that acquires a die cushion load signal indicating a die cushion load generated in the cushion pad of the die cushion device; and a double blank detecting unit that detects, as a double blank, a state where a plurality of the blank materials are overlapped, based on the die cushion position signal and the die cushion load signal that are acquired.

The rotary tablet press comprises a machine base assembly and detachable module. Granulation is fed into the module from the hopper and travels into the feeder chamber. The base assembly comprises motorized pressure roll assemblies and a turret drive assembly. The detachable module comprises a module base, turret base, turret, cam body, cams, feeder, tablet discharge chute, hopper, upper enclosure, and guard doors. The rotary turret comprises upper punches, dies, and lower punches. As the turret rotates, the dies move underneath the feeder chamber. The rotary feeder paddles move the granulation and assist with feeding powder to the dies. Punches travel along cam tracks as the turret rotates and compresses the powder into a tablet when the punches contact the pressure rolls. An ejection cam pushes the lower punch in the upward direction and a take-off bar mounted just above the die table directs the tablet into a discharge chute. The detachable module is sealed by incorporating an upper enclosure.

A die arrangement for pressing, sintering or stamping comprising: a die body with a cavity extending from an opening at a first end of said die body to an opening at a second end of said die body, and one or more moving parts arranged around the opening at said first end of said die body, wherein each moving part is displaceable between a first position and a second position. The die body may be configurable to receive a die plunger at said second end of said die body, said plunger being displaceable within the cavity. The die arrangement may further comprise an outer sleeve mounted on the die body, the outer sleeve being coaxial with the die body and having a first outer sleeve portion nearest to the first end of said die body, and one of: a second outer sleeve portion nearest to the second end of said die body; a second outer sleeve portion fixedly attached to the plunger base nearest to the second end of said die body; or, a second outer sleeve portion extending directly from the plunger base nearest to the second end of said die body, the second outer sleeve portion and the plunger base being a single unitary component.

The invention relates to a press device (100) for a powder press (1) for producing pellets from a compressible material, wherein the powder press (1) comprises a press frame (2) that has an upper and a lower frame portion, an upper and/or lower punch arrangement (3) which each comprise a tool, and a die arrangement (4), which define a mold cavity into which the compressible material is introducible, and a drive unit (5) that is operatively connected to the punch arrangement (3) and/or the die arrangement (4), wherein, in order to form the pellet, the upper and/or lower punch arrangement (3) and the die arrangement (4) are movable relative to one another along a pressing axis (6) by means of the drive unit (5) and are able to be pressed against one another. The press device (100) has multiple tool planes (10) that are arranged above one another, which each comprise a carrying element (12) and a push-in element (50) that is able to be received on the carrying element (12) and arrested, on which at least one of the tools is receivable.

Concrete product machine apron gap adjustment by actuating a gapper mechanism to set a desired gap between a reciprocally-movable apron plate and an interchangeably installable mold assembly installed in a concrete products machine. The gapper mechanism sets a desired gap between the machine apron plate and the mold assembly by injecting an index amount of hydraulic fluid into fluid communication with the rod side of a primary apron plate positioning cylinder, causing the machine's apron plate to retreat a desired gap distance away from an engaged position against the mold assembly.

A tool installation aid for installing a tool into a press includes a holding console attachable to a press, and a tool-changing plate in or on which a tool is attachable, wherein the tool-changing plate can be placed onto a receiving element of the holding console, a drive device, drivable by a motor or manually, is disposed in the tool-changing plate and by way of which the tool-changing plate is displaceable on the receiving element in the direction toward the press to be transferred from the receiving element onto the clamping plate of the press, the drive device includes at least one driven first drive element, and the receiving element includes at least one non-driven second drive element, the first and second drive elements being operatively connected for displacing the tool-changing plate.

The invention concerns a sheet metal press system and a method used in connection therewith. The sheet metal press system comprises at least one sheet metal press having an opening through which a tool, which comprises an upper die, a lower die and a tool changer interface, can pass during a tool change performed by means of a tool changer device. The tool changer device comprises at least one automated guided vehicle, running on a shop floor and capable of lifting and lowering a tool by interaction with the tool changer interface of said tool, wherein a guide path for said at least one automated guided vehicle runs from outside and into said at least one sheet metal press through said opening. The method comprises alternating use of a first and a second automated guided vehicle during a tool changing operation.

A die arrangement for pressing, sintering or stamping comprising: a die body with a cavity extending from an opening at a first end of said die body to an opening at a second end of said die body, and one or more moving parts arranged around the opening at said first end of said die body, wherein each moving part is displaceable between a first position and a second position. The die body may be configurable to receive a die plunger at said second end of said die body, said plunger being displaceable within the cavity. The die arrangement may further comprise an outer sleeve mounted on the die body, the outer sleeve being coaxial with the die body and having a first outer sleeve portion nearest to the first end of said die body, and one of: a second outer sleeve portion nearest to the second end of said die body; a second outer sleeve portion fixedly attached to the plunger base nearest to the second end of said die body; or, a second outer sleeve portion extending directly from the plunger base nearest to the second end of said die body, the second outer sleeve portion and the plunger base being a single unitary component.

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 press for producing a molded part from pourable material has an apparatus for driving a die that includes a cylinder unit having a cylinder housing and having a cylinder piston. The cylinder housing is the actuator of the cylinder unit and the cylinder piston is the stator of the cylinder unit.
