In case of hammer-forging, it has heretofore been said that the forging effect is greatly influenced by anvil weight and rigidity of supporting material (represented in the form of equivalent spring) or, in other words, anvil weight ratio (anvil weight over hammer head weight) and rigidity of spring. However, the writer has found that, in case of free forging, as far as anvil weight ratio is above a certain value which is far smaller than that having been said to be the limit, there exists little infiuence of anvil weight ratio and rigidity of spring on hammer-forging effect. Result of experiments conducted and theoretical explanation therefor are given herein.
