An automated mold change system, for use with a concrete products machine of a type having a products forming section and a feedbox assembly section, includes a mold exchange assembly coupled to an underside of the feedbox assembly section and vertically moveable therewith, a mold transfer assembly on an opposed side of the products forming section from the feedbox assembly section, and mounts on the products forming section configured to retain a mold assembly thereon. A mold exchange path runs axially between the mold exchange assembly and the mounts on the products forming section and intersects a mold transfer path of the mold transfer assembly at a load-unload position, wherein the mold exchange assembly is configured to lift a mold off of the mounts and onto the mold transfer assembly at the load-unload position.

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 method and device for production of a combustion chamber tube for restraint systems in vehicles. The combustion chamber tube is embossed by several embossing dies arranged stellate around the combustion chamber tube and movable by an annular compression module with several punches movable in synchronized fashion in the radial direction and two inner punches extending into the ends of the combustion chamber tube, each with a support mandrel and a shaping mandrel movable relative to support mandrel. The combustion chamber tube is embossed from the outside by the embossing dies radially movable via punches against the support mandrels and the ends of the combustion chamber tube are shaped by shaping mandrels movable relative to support mandrels when the embossing dies are closed.

The invention relates to a tool changing device (1) for a forming press (2), in particular a press brake, comprising at least one tool magazine (3, 4) and at least one transfer device (5, 6) for the transfer of the forming tools (7, 8) of the at least one tool magazine (3, 4), which are storable in the at least one tool magazine (3, 4), from the at least one tool magazine (3, 4) to the forming press (2) and in the reverse direction, wherein the at least one transfer device (5, 6) has a drivable thrust chain (9, 10) for the transmission of compressive and tensile forces.

A tablet press for producing tablets including: a press chamber, a receiving chamber, a first material container having the first active substance with a first dosing device, a controller, and an input device. The press chamber has an extendable upper punch, an extendable lower punch, and a die. The input device inputs a target indicating a number of produced tablets and a target mass indicating a quantity of the first active substance and transmits the target number and the target mass to the controller. The controller actuates the first dosing device, the upper punch, and the lower punch such that a quantity of the first active substance that corresponds to the target mass is filled into a central opening of the die and pressed by the punches to form a tablet, and to repeat until the target number of tablets are produced.

A system for loading and unloading top and bottom tools in a press machine comprises a cart, an upper platen, first and second upper platen loading arms, a lower platen, and first and second lower platen loading arms. The cart supports the top and bottom tools and includes a latch to couple to the press machine and a conveyor mechanism to move the tools. The upper platen, positioned in the press machine, retains the top tool and includes top tool clamps to clamp the top tool. The first and second upper platen loading arms include rollers to fit into roller slots of the top tool. The lower platen, positioned in the press machine beneath the upper platen, retains the bottom tool and includes bottom tool clamps to clamp the bottom tool. The first and second lower platen loading arms include tracks to fit into T-slots of the bottom tool.

A gathering operation includes a restraint operation of moving forward a left lower tool retention member so as to restrain a reference lower tool with the left lower tool retention member, an inserting operation of moving forward a right lower tool retention member so as to insert the right lower tool retention member into an insertion hole of a target lower tool, and an execution operation of moving the left and right lower tool retention members along a left-right direction so as to come close with each other. If a failure of the inserting operation is determined, a control device performs a retry operation of moving forward the right lower tool retention member again so as to insert the right lower tool retention member into the insertion hole (141) of the target lower tool after moving backward the left lower tool retention member.

An isolator unit includes a housing enclosing an internal space, a door configured to close an opening of the housing to isolate the internal space of the housing from outside, a die disposed in the internal space of the housing and filled with a powdery material, a punch disposed in the internal space of the housing and fitted into the die, a compression rod inserted to the internal space of the housing and including a proximal end exposed from the housing to receive pressure applied from a separately-provided compressor, and a distal end configure to compress the powdery material in the die via the punch, and a fixture configured to fix the proximal end of the compression rod to the housing in a state where the proximal end of the compression rod is pressed by the separately-provided compressor to compress the powdery material in the die via the punch.

An apparatus includes a fixed assembly and a reciprocating assembly. The fixed assembly includes a hopper, a first gas manifold, and a dispensing chamber, and the reciprocating assembly includes a channel assembly defining a channel conduit, a shield plate vertically aligned therewith, and a second gas manifold. The reciprocating assembly may move, in relation to the fixed assembly, to a first position to enable the channel conduit to be filled with bulk compressible material from the hopper, a second position to enable compressible material to be pushed from the channel conduit to the dispensing conduit and to be compressed in the dispensing chamber according to a first gas directed through the channel conduit by the first gas manifold, and a third position to enable the compressed material to be pushed out of the dispensing conduit according to a second gas directed through the dispensing conduit by the second gas manifold.

A device for press-processing workpieces includes: a plurality of workpiece processing units arranged along a curved path; and a workpiece transfer unit that is rotatable about a rotation axis and that is configured to move at least one workpiece successively along the workpiece processing units. At least one of the workpiece processing units is a press-processing unit that is configured to perform a press-processing operation on the workpiece.
