Press frame assembly
A press frame assembly includes a base plate, a load cell, and an overload protection element; a first plate, a plurality of guideposts disposed on the base plate; a plurality of springs disposed on the plurality of guideposts, a displacement transducer arranged to monitor a linear displacement of the first plate, and a controller, in communication with the load cell and the displacement transducer. The first plate is disposed to translate on the plurality of guideposts, and wherein the springs are disposed to urge movement of the first plate in relation to the base plate. The load cell is arranged to monitor a load exerted upon the base plate. The controller generates a signal that is based upon the load exerted upon the base plate or the linear displacement of the first plate in relation to the base plate.
DEVICE AND METHOD FOR CONTINUOUSLY PRODUCING AN AT LEAST PARTLY HOLLOW SHAFT HAVING A VARYING INNER AND/OR OUTER DIAMETER
A device and method for continuously producing an at least partly hollow shaft having a varying inner diameter includes forging tools that are arranged centrally symmetrically about a forging axis and are driven radially, a clamping chuck for holding an at least partly hollow cylindrical blank, and a counter-holder for axially supporting the blank. The counter-holder has a base and a counter-holder mandrel arranged on the base and extending axially into a central cavity in the blank. The mandrel is formed of at least two parts, wherein a first part of the counter-holder mandrel constitutes an inner part and a second part of the counter-holder mandrel constitutes an outer part surrounding the inner part. At least the outer part can be moved axially relative to the inner part.
FRAME STRUCTURE, PROCESSING APPARATUS, METHOD OF MANUFACTURING COMPONENTS, METHOD OF MANUFACTURING ROLLING BEARING, METHOD OF MANUFACTURING VEHICLE, METHOD OF MANUFACTURING MACHINE AND PRESS APPARATUS
A frame structure includes a C-shaped frame having a front side that opens in a forward and rearward direction among the forward and rearward direction, a leftward and rightward direction and an upward and downward direction, which are perpendicular to each other, an upper action section supported by an upper front portion of the C-shaped frame, and a lower action section supported by a lower front portion of the C-shaped frame, wherein, when a reaction force is applied through the upper action section, the C-shaped frame is deformed such that a displacement of the upper action section in the forward and rearward direction, which occurs according to an elastic deformation of the C-shaped frame, is canceled out and such that a displacement of a pivotal movement about a leftward and rightward direction axis of the upper action section is canceled out.
Tool For Realising A Press Quenching And Tempering Method
The invention relates to a tool for realising a press quenching and tempering method for a rotational symmetric tool, in particular for a gear wheel, wherein the tool is at least in part manufactured as an additive and wherein, in an additively manufactured area of the tool, is formed at least one pipe for guiding a fluid.

System of a frame for presses
A system of a separable frame for presses and press frames (1), the respective press frame (1) comprising uprights (2) and a head piece as an upper cross connection (3) and a press table as a lower cross connection (4), which as structural units form a closed frame that absorbs static and dynamic forces for any required functions of a press such as the drive of a ram used for forming with tools. The uprights (2) are attachable laterally or longitudinally to the cross connections (3, 4) by non-positive or non-positive and positive joining geometries (5) and releasable connector (5.1). The proposed press frames (1) have a reduced vertical deflection (v2) compared to press frames joined by tie rod bracing (6).

System for adjusting sliding blocks of a movable crosspiece of a press
An adjustment system for adjusting the position of at least one sliding block of a movable crosspiece of a press with respect to the respective column of the press on which the sliding block may slide, a first wedge is integral with the movable crosspiece, a second wedge is sliding on the first wedge, a pin defining an axis and having a first eccentric end accommodated in a cavity provided in the second wedge, a first actuating member adapted to rotate the pin causing the translation of the second wedge along a direction transversal to the axis, a second actuating member adapted to translate the pin from a first locked position to a second unlocked position in which the pin can rotate about the axis.

Crosshead for use as an upper and/or lower beam in a press
A crosshead (1) for use as an upper and/or lower beam (50, 60) in a press (100), in particular an open-die forging press or a closed-die forging press, comprises an upper chord (2) and a lower chord (5) connected to the upper chord (2) via a first and a second lateral upright (3, 4). The first lateral upright (3) is arranged in the region of a first distal end (6) and the second lateral upright (4) is arranged in the region of a second distal end (7) of the crosshead (1). The crosshead (1) has a truss support structure (8) between the two lateral uprights (3, 4) by which the upper chord (2) and the lower chord (5) are additionally connected to one another.
