<p>The hammer (2) comprises: a jacket (3), in turn comprising: an inner chamber (32), an inlet circuit (4) for the entry of compressed air, and an outlet circuit (5) for the exit of compressed air. The hammer further comprises a motion mechanism (7), for generating a vibratory motion under the action of compressed air; and a punch or beater (6), connected to said motion mechanism (7), for coming into contact with the casting to be de-cored, forming a first end of the hammer. The inlet circuit (4) comprises an inlet connector (41) for connecting the hammer to a compressed-air circuit; said inlet connector being located at a second end of the hammer (2), opposite to the end where the punch or beater (6) is located. The outlet circuit (5) comprises an outlet connector (54) for connecting the hammer (2) to an air recovery circuit. The outlet connector (54) is located at the second end of the hammer (2), in proximity to the inlet connector (41).</p> |
