The present disclosure provides an oil hydraulic press including a support frame, at least one main cylinder assembly and at least one fixed die table. The at least one main cylinder assembly and the at least one fixed die table are disposed in the support frame. A pressing mechanism is formed between the at least one main cylinder assembly and the at least one fixed die table. The support frame is in an annular or ring-like shape and is configured for fixing the at least one main cylinder assembly and the at least one fixed die table. The main cylinder assembly and the fixed die table can be fixed by the support frame, which forms a ring-like structure, can be operated in one, two or multiple sets in parallel, and all can realize pressing manufacture. The oil hydraulic press has less components, reduced material consumption and low manufacturing cost.

The invention relates to a die for arrangement in a press, wherein the die extends along an axial direction between two end faces and forms an inner peripheral surface between the end faces, wherein the die extends from the inner peripheral surface along a radial direction toward an outer peripheral surface and toward at least one centering surface that is disposed in the radial direction on a first diameter, wherein the die has a pressing zone that is spaced apart from the end faces and, in the vicinity of the pressing zone, the die has a greater maximum first stiffness, at least relative to zones of the die that are arranged on the end faces, compared to a pressing force acting on the inner peripheral surface in a direction of a normal vector, and wherein the maximum first stiffness is at least 10% greater than a minimum second stiffness that is present in at least one zone that is arranged on one of the end faces.

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.

A device for supporting stripper head on a mold box of a concrete product machine mold assembly. The device includes a set of attachment hardware that connects a stand-off leg to a stripper head plate to support the stripper head with the stripper head plungers disposed in respective protected positions within respective plunger receptacles of the mold box. The hardware set comprises a ferrous metal portion configured to be carried by the stripper head plate and a magnetic portion carried by the stand-off leg in a position to magnetically engage the ferrous metal portion and allow for removable attachment of the stand-off leg to the stripper head plate when the ferrous metal portion is carried by the stripper head plate.

In a press forming device and a press forming method for press-forming a workpiece that includes a load control region to which a constant load is to be applied, the press forming device includes a die unit that includes an upper die and a lower die that sandwich the workpiece; a slider that holds the upper die; a bolster that holds the lower die; a pressing mechanism that presses the slider toward the bolster at a plurality of pressing points; and one or more support blocks arranged around the die unit, between the bolster and the slider. The support block is arranged farther outward than the pressing points, on a line that extends, in an arrangement direction of the pressing points, from a reference point on an end portion of the load control region.

A rework press assembly for reworking a dimensionally non-conformant component is provided. The rework press assembly includes a frame, a die coupled to the frame and configured to contact a first portion of the component, and a ram. The ram is coupled to the frame opposite the die with respect to an axis of the rework press assembly and is configured to contact a second portion of the component. The ram and the die define a component cavity therebetween. At least one of the die and the ram has a first length, relative to the axis, in response to the rework press assembly being at a first thermal condition. The at least one of the die and the ram has a second length, relative to the axis, in response to the rework press assembly being at a second thermal condition, and the second length is greater than the first length.

A graphic arts support assembly is operable to be used with a graphic arts plate assembly in a press. The graphic arts support assembly and the plate assembly are configured for removable association with a lift mechanism including a shiftable lift element. The support assembly includes a graphic arts magnetic support structure operable to removably support the graphic arts plate assembly. The magnetic support structure includes a support plate, a magnet fixed relative to the plate, and an alignment element projecting from the support plate. The support assembly is operable to be mounted on the lift mechanism so that the lift element is aligned with a lift opening of the support plate, with the lift element shiftable through the lift opening to locate at least part of the graphic arts plate assembly away from the support plate.

A rotary tablet press comprises a press housing having bottom and top ends. A compression assembly in the press housing includes pressure roll assemblies. A drive housing extends outwardly from the top end of the press housing. A motor drive assembly is in the drive housing and comprises a turret motor rotationally driving a drive shaft extending downward from the turret motor, the drive shaft being mounted for axial movement along a vertical axis in the turret motor. A drive shaft control is operable to controllably raise and lower the drive shaft. A turret assembly is mounted to the press housing below the drive housing and about the vertical axis so that the pressure roll assemblies engage the turret assembly, the drive shaft engaging the turret assembly to rotate the turret assembly responsive to the drive shaft control lowering the drive shaft.
