Abstract
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.

A crosshead (1) for use as an upper or lower beam (50, 60) in a press (100), in particular an open-die forging press or a closed-die forging press, comprising:
- an upper chord (2);
- a lower chord (5), the lower chord (5) being connected to the upper chord (2) via two lateral uprights (3, 4), including
- a first lateral upright (3) and
- a second lateral upright (4),
- wherein the first lateral upright (3) is arranged in a region of a first distal end (6) of the crosshead (1),
- wherein the second lateral upright (4) is arranged in a region of a second distal end (7) of the crosshead (1),
- wherein the crosshead (1, 50) 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,
- wherein the upper chord (2) and the lower chord (5) each have a central opening (9, 10), the central openings (9, 10) being centrally arranged and in alignment with one another,
- wherein the central openings (9, 10) define a central region (11) of the crosshead (1) and are provided for connection to a main cylinder (110) of the press (100),
- wherein the upper chord (2) and the lower chord (5) each comprise, on both sides of the respective central opening (9, 10), respective further openings (12, 13, 14, 15) which are pairwise in alignment with one another, for connection to a first and a second press cylinder (111, 112) of the press (100),
- wherein the truss support structure (8) comprises a plurality of transversely extending tension ribs (20, 21, 22, 23) that extend from the central region (11) of the lower chord (5) in the direction of the end faces of the upper chord (24, 25) and are firmly connected to the lateral uprights (3, 4),
- wherein two respective tension ribs (20, 21, 22, 23) arranged parallel to one another are each connected to one another via a flat element (26, 27), and
- wherein each of the flat elements (26, 27) has an opening (28, 29) that is in alignment with a pair of the further openings (12, 13, 14, 15).
