A pneumatic die transfer system for a press machine comprises at least two primary roller rails and at least two secondary roller rails set in respective T-slots in a bolster. The primary roller rails are perpendicular to the secondary roller rails. Airbags below each roller rail are selectively inflated to elevate either the primary or the secondary roller rails above the bolster face. The secondary roller rails each have a plurality of discontinuities configured to receive the primary roller rails and their associated airbags in an intersecting fashion. As a result, the bolster can be easily fabricated with intersecting T-slots and relatively few roller rails are needed to achieve fully orthogonal conveyance of a heavy die over the face of a bolster.

Disclosed is a system and a method for exchanging vertically segmented rotor segments (16) on a rotary tablet press (34). The system comprises a rotor (10) comprising at least two vertically segmented rotor segments (16), a transfer unit (36) and an assembly carriage (38).

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.

A frame integrated vacuum hot press comprises a frame chamber including a vacuum space having an opened side; a door installed to the frame chamber to open or close the opened side of the vacuum space; a heating chamber including a heating space and a heater heating an object to be formed which is loaded in the heating space; and a cylinder which is connected to the frame chamber to apply pressure to the object to be formed which is loaded in the heating space of the heating chamber.

A uniaxial press for shaping pellets by compressing powder in a die by punches. The uniaxial press can be used in a restricted and hostile environment and includes small modules that can pass separately through narrow openings, the modules being assembled by placing over columns and by screwing, therefore by remote handling in the confined space where the press is to operate without requiring any further intervention. The actuation is generally exclusively electromechanical.

A progressive cold forming machine and a robot for automatically changing a cutoff cassette, tooling cassettes, a transfer slide and transfer cam. A loading area adjacent the machine and robot has provisions for supporting a tooling cassette pallet and a transfer slide and camshaft pallet and a holding area for temporarily receiving some of the componentry being exchanged.

A full-automatic wireless die change cart and system for a press. The full-automatic wireless die change cart includes an upper working table and a lower working table which are connected together up and down of driving devices. The lower working table is driven by a driving device I to move back and forth, while the upper working table is driven by a driving device II to move rightwards or leftwards. Baffles, die lifting arms, and guide rails, all in parallel to one another, are disposed in order from outside to inside at two opposite ends of the upper working table, and push-and-pull devices, baffles, and fixed supporting plate assemblies are disposed in order from outside to inside at the other two ends perpendicular to the two ends.

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.

In a tool storing device handling a tool mounting stocker in which a punch and a die of a press brake are mounted in one stocker with rear surfaces facing each other, each of the stockers is supported on both sides by endless belts having one driving shaft, and the endless belts are circulated so that each of the supported stockers does not protrude to a worker side, whereby a position of a path line of the appropriate one of the stockers can be freely positioned at a position of the path line PL of a tool holder on the press brake side. This enables rapid and easy tool replacement by a bending robot by storing not only the tool made of the punch and the die but also the hand for the robot together.

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.
