150 Tons Power Press

Power presses that shear, punch, form, or assemble metal or other material by means of tools or dies attached to slides. Power presses can be mechanical, hydraulic or pneumatic. In mechanical power presses, tools and dies are mounted on a slide or ram, and move away from the stationary bed containing the lower dieIt is guided in the frame of the machine — either a “C” frame [open back inclined (OBI)] or straight side frame — to give a definite path of motion. The two most common types of power presses are mechanically and hydraulically powered.Rated press capacity is the tonnage pressure the slide can safely exert at the bottom of the stroke. Mechanical press capacity is typically based on the bending capacity of the main shaft (crank, toggle, or eccentric shaft). It is important to know and understand 1.)
