Abstract

The forging machine with the anvil moving in the opposite direction to the impact member above, uses a low viscosity fluid to control their movement. This fluid consist of a mixture of gas and liq. The outer frame is open at the top, and contained an inner frame with a hollow chamber for the workpiece, and with the anvil mounted on the base. The inner frame is mounted between guides to travel inside the outer frame, and incorporates an upper chamber for a piston which carries the impact member underneath. The base carrying the anvil has chambers for the fluid, which can then pass up vertical hollow guide pillows to the upper chamber for the required movement. Pillars inside the outer frame extend into these chambers.
