An automatic hammer machine is provided to have an effect of being capable of exchanging only a deformed component in a case of a hitting part of a hammer or a penetration pole a during a hitting step. In an automatic hammer machine, a long hole(11) is formed at a lateral side of a sleeve casing(10) in the longitudinal direction. Upper and lower sprockets(21,23) are mounted at an outer side of the sleeve casing for arranging the upper and lower sprockets at an upper part and a lower part of the long hole respectively. The upper sprocket operates by a driving motor(27). A chain(25) circulates a space between the upper sprocket and the lower sprocket along a direction of the long hole. An L-shape latch(29) is mounted at the chain. A hammer(30) is arranged to be capable of ascend and descend in a hollow part(13) of the sleeve casing. The hammer ascends upward the sleeve casing when the latch ascends up by the chain, wherein the latch is configured to be hung on a latch groove(31) which is formed at a lateral side of the hammer. The hammer hits an anvil(50) as a free-falling type when the latch is out of the latch groove of the hammer in the upper part of the sleeve casing. A grip(40) is mounted on a lower part of the sleeve casing. And, the anvil connected to a penetration pole(55) is mounted at the grip.
