<p>The invention concerns an impact machine comprising an impact unit (1) with a ram (13) and an anvil (3) provided under the impact unit, on which anvil a tool unit (2) can be placed. More particularly the invention concerns an impact machine for working by the employment of a high kinetic energy, characterised in that the anvil assembly, which includes the anvil (3) and the tool unit (2) with tool an abject to be worked, is movable in the vertical direction, and that means are provided to move the anvil assembly upwards towards the ram to meet the ram as it is moving, simultaneously with the ram being moved downwards.</p> |
