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.

A bearing block unit for supporting a continuous casting roll, including a bearing block and a roller bearing disposed inside the bearing block. The bearing provides an inner ring raceway, an outer ring raceway, and at least one row of rolling bodies disposed between the inner and outer ring raceways. The inner ring raceway is formed by a complete and continuous independent inner ring. The inner ring is fitted on a roll shaft of the continuous casting roll during installation, for the purpose of supporting the continuous casting roll. The outer ring raceway is at least partially formed by processing of an inner surface of an inner hole of the bearing block. The present invention also relates to a continuous casting roll line and a continuous casting machine using the bearing block unit.

A bearing block assembly for supporting a calender roll having a housing including a preload access port, a base surface, and a first side and a second side. A first contact surface on the first side extends from the base surface at a first angle, and a second contact surface on the second side extends from the base surface at a second angle. Within the housing is a first bearing block having a first bearing block surface and a first bearing bore, a second bearing block having a second bearing block surface and a second bearing bore, and a third bearing block having a preload surface and a third bearing bore. The first bearing block surface is disposed over the first contact surface, the second bearing block surface is disposed over the second contact surface, and the preload surface is positioned between the preload access port and the base surface.

Provided is an electrode notching mold for a secondary battery having an auto-balance unit. The electrode notching mold for the secondary battery having the auto-balance unit includes a cover portion including an upper plate and a lower plate, a mold portion having a film, a plurality of ascending-descending portions, a plurality of guide portions, and a pressing portion, and also, a plurality of auto-balance units connected to a spherical bearing on the central axis is coupled to an upper body and a lower body and performs a function of alleviating vibration.

The present disclosure provides a shear assisted extrusion press comprising a stem and plunger assembly comprising a main piston configured to generate an extrusion force, a stem assembly comprising a stem having a first end and a second end, wherein the second end connects to a rotary piston that connects to the stem and plunger assembly, wherein the main piston exerts the extrusion force on the stem such that the stem moves axially, and at least one piston motor coupled with the stem and configured to drive a rotational movement of the rotary piston and the stem, and a container assembly comprising a container holder, a container configured to receive a billet and the first end of the stem, and at least one hydraulic motor positioned in the container holder with the container, wherein the at least one hydraulic motor is configured to drive a rotational movement of the container. The rotary piston and the stem are configured to rotate and move axially such that the stem moves the billet through the container to extrude a part, and the container and the billet are configured to rotate together while the container does not move axially.
