50MN Two-Column Open Die Forging Press

Description

LS Heavy Industry Engineering Co., Ltd. 50MN push-down hydraulic forging presses with two rectangular columns are directly oil-hydraulically driven. They offer a high forging speed and better visibility of the forging area for operator, as same as pull-down forging presses.

They have a pre-stressed frame with two built-in tie rods for each column ensuring high rigidity and antifatigue. Individual casting upper crossbeam and bottom crossbeam is for easy transportation and installation, so they are for medium or large forging forces. Two-rectangular-column is better for withstanding eccentric load. It also ensures equal and uniform distribution of loading between two columns.

High tensile pre-stressed tie rods ensure a high working load, together with casting frame to keep a very low working stress. Special columns guide is designed to absorb shock from eccentric loading.
