A bailing apparatus may include a multi-component bolster assemblies that may ease installation and removal, reduce wear and tear and maintenance, and/or improve baling efficiency by reducing material waste, imperfections, and/or contamination. The bolster assemblies may include a plurality of coupling portions that engage a hydraulic rod and may enable the bolster assembly to self-center within a press chamber during normal baling operations. The bolster assemblies also may include an island portion that may be attached to the coupling portions and to a bolster cap, and the latter may be attached using retainer bolts having substantially planar heads that may define lips that run about frustums. The bolts may substantially planar head may reduce irregularities in the bale and the lips may prevent material seepage into the bolster assemblies.

Improved balers may include a traveling chute that may reduce wear and tear and maintenance, and/or improve efficiency by reducing downtime. The traveling chute may include moving guides that include channels that engage tongues of stationary guide rails disposed on a baler. For example, the channels may be substantially rectangular channels that run the length of the moving guide. Similarly, the stationary guides may include substantially rectangular tongues and the moving guides may slide across the tongues and upper surfaces of the stationary guides as the traveling chute moves between various positions. The moving guides may include polyoxymethylene inserts in which the channels may be provided. The moving guides and stationary guides may be provided as a kit for attachment to various baling apparatuses. Additional features and components also are described.

An extrusion apparatus (200) and method to extrude ceramic precursor batch through a die to form a honeycomb extrudate (100), and an apparatus assembly method, are provided. The apparatus comprises a tail ring device (202) comprising a tapered inner opening configured to funnel the batch downstream from upstream extrusion hardware, wherein an inner surface (318,320) of the tail ring device (202) comprises no pockets or protrusions to disrupt batch flow; a bow control device (204) disposed on the tail ring device (202) comprising an aperture (414) defined by shutter plates (S1-S4) to control a bow of the honeycomb body extrudate (100) formed from the batch flowing through the die by adjustment of the shutters (S1-S4); and an edge flow control device (206) disposed on the bow control device (204) comprising edge plates (816) configured to protrude into the batch to control an edge flow of the batch flowing to a periphery of the die.

A hydraulic forging machine and a method for replacing an upper anvil block thereof are disclosed. The hydraulic forging machine includes locking hydraulic cylinder that is fixed to a movable beam of the hydraulic forging machine when the hydraulic forging machine is in operation. The locking hydraulic cylinder is configured to provide a locking-unlocking function between an upper anvil block of the hydraulic forging machine and the movable beam. The locking hydraulic cylinder has its hydraulic power source supplied from a main hydraulic cylinder or a return hydraulic cylinder, which is also fixed to the movable beam. The present disclosure not only enables an oil supply circuit for the locking hydraulic cylinder to move together with the movable beam, but also simplifies the oil supply circuit for the locking hydraulic cylinder, resulting in an improved reliability of the hydraulic forging machine.

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.
