PLATE-BENDING HYDRAULIC PRESS OF A PLATE-AND-FRAME TYPE Russian patent published in 2005 - IPC

FIELD: metal forming.

SUBSTANCE: the invention concerns to the field of metal forming, in particular, to the plate-bending hydraulic presses. The press contains a stand, a bending mechanism consisting of a puncheon located in the upper part of the stand and a lower die. The lower die is located on plungers of hydraulic cylinders with a capability of up and down motion. The stand is made in the form of a frame. The lower die is installed on a sliding block, which is located on the plungers of the hydraulic cylinders uniformly located along the whole length of the sliding block. The pressing force from the hydraulic cylinders is applied in a directed along the axis of the lower die pass through the vertex of angle of the puncheon located along the center of thickness of the stand. In result the invention ensures increased quality of the plates bending, decreased metal consumption and labor input at production of the plate-bending hydraulic presses.

EFFECT: the invention ensures increased quality of the plates bending, decreased metal consumption and labor input at production of the plate-bending hydraulic presses.
