Power Hammer
Resumen del Libro
High Quality Content by WIKIPEDIA articles! Power hammers are mechanical forging hammers that use a non-muscular power source to raise the hammer preparatory to striking, and/or to propel it onto the work being hammered. They have been used by used by blacksmiths, bladesmiths, metalworkers, and manufacturers since late in the first decade of the 19th century. A typical power hammer consists of a frame, an anvil, and a reciprocating ram holding a hammer head, and is a direct descendant of the trip hammer, differing by storing potential energy in an arrangement of mechanical linkages and springs, in compressed air, in or steam, and by accelerating the ram on the downward stroke, providing more force and energy than simply allowing the weight to fall would do. Others, like steam drop hammers, use the power source to raise the ram, but let it be propelled solely by gravity. Power hammers are rated according to the weight of the ram, and range between 25 pounds and 125 tons.
