9. A high-pressure water descaling method for a forged piece, which is characterized in that the high-pressure water descaling device before forging of the forged piece according to claim 5 is adopted for descaling, and the method comprises the following specific steps:
step a, before descaling, adjusting the angle and the distance between the two spray pipes and the distance between the two springs according to the shape characteristics of the forge piece, so that the forge piece can theoretically pass between the two springs under the condition of not contacting with the springs;
and b, during descaling, the clamping equipment clamps the forge piece to pass through the space between the two springs and then enter the spraying box along a straight line to perform spraying operation, if the forge piece is contacted with the springs, the springs deform, namely the forge piece withdraws, and the clamping action of the clamping equipment is readjusted until the forge piece is not connected with the springs when passing through the space between the two springs.
