The working principle is as follows:

when the die is in operation, the die is placed in the limiting frame 3, the hydraulic rod 5 drives the upper protective cover 701 to move downwards when moving downwards, the first spring 703 presses the upper protective cover 701 to enable the upper die 6 to coincide with the top block 709, after the upper die 6 strikes a forged piece, the upper protective cover 701 coincides with the lower protective cover 714, the hydraulic rod 5 contracts, the third grooves 710 formed in the left side and the right side of the lower protective cover 714 prop against the projection 713 under the tension action of the second spring 712, when moving upwards, the two projections 713 have opposite downward acting forces, the position of the upper protective cover 701 is fixed, the hydraulic rod 5 continues to contract, the hydraulic rod 5 drives the upper die 6 to move upwards, because the position of the upper protective cover 701 is fixed, the connecting rod moves downwards relative to the rectangular opening 702, the supporting rod 708 keeps fixed along with the connecting rod 705, and the position of the top block 709 is not changed by the supporting rod 708, at this time, the ejecting block 709 is separated from the upper die 6, which is beneficial to ejecting the forged piece out of the upper die 6, when the hydraulic rod 5 retracts to a certain position, because the limiting block 704 moves upwards, the first spring 703 retracts, the bump 713 is ejected into the first groove 706 due to the action of the third groove 710, the second spring 712 and the bump 713 retract into the first groove 706, when the bump 713 passes through the third groove 710, the upper protective cover 701 does not receive the vertical acting force, the first spring 703 and the second spring 712 return, the first spring 703 returns the upper protective cover 701, the second spring 712 returns the bump 713, so that when impact is performed each time, there is an ejecting action of the upper die 6, which can ensure that the position of the forged piece remains unchanged as much as possible, which can provide favorable conditions for the next knocking, when the hydraulic rod 5 moves downwards, the upper protective cover 701 is driven to move upwards, when the upper protective cover 701 moves downwards, the two first inserting rods 14 are driven to move downwards, the two first inserting rods 14 push the corresponding pistons 9 to push the two pistons 9 downwards, at the moment, gas is discharged out of the interior of the sleeve 8 through the gas pipe 11 and is rapidly extruded, in the process of rising, because of the rotation of the jacking block 709, oxide skin is separated from the surface of the forged piece, the flow velocity of the gas is increased, the oxide skin generated on the surface of the forged piece is blown to the left side of the limiting frame 3 and falls into the interior of the dirt collecting box 12 through the leakage groove 13, after one-time beating is completed, the two first inserting rods 14 are far away from the corresponding sleeve 8, at the moment, the pistons 9 are reset under the action of the third springs 10, the gas is filled in the interiors of the two sleeves 8, the next-time working is facilitated, the generated oxide skin is removed, the quality of the forged piece is improved, and when the hydraulic rod 5 moves downwards, the upper protection cover 701 is driven to move downwards, the two pipelines 18 are driven to move downwards together when the upper protection cover 701 moves downwards, at the moment, the upper end of the rod wall of each pipeline 18 is in threaded connection with the top of the shell 1, the two pipelines 18 rotate, the two pipelines 18 drive the corresponding spray heads 23 to rotate, the three-way pipe 20 is not driven to rotate by the waterproof bearings 19, when the descending position of each pipeline 18 is lower than the liquid storage tank 15, the forging liquid stored in the liquid storage tank 15 is output at the moment, the forging liquid can be uniformly distributed on the surface of a forged piece, the quality of the forged piece is improved, when the upper protection cover 701 descends, the L-shaped ejector rod 29 is driven to move downwards, when the L-shaped ejector rod 29 descends to the bottom, the movable frame moves leftwards when the movable block 25 is pushed, the movable block 25 moves leftwards to drive the steel rope 26 to move leftwards, the steel rope 26 pulls the rotary block 27 to rotate the rotary block 27, when the L-shaped push rod 29 moves upward, the fourth spring 28 pulls the rotating block 27 until the rotating block is reset, so that the oxide skin accumulated in the leakage groove 13 can be ejected out, the leakage groove 13 is dredged to facilitate the operation of removing the oxide skin, the accumulation of the oxide skin is avoided, a clean working environment is provided for the next forging of the forge piece, the influence of the oxide skin is avoided, when the upper protective cover 701 descends, the second inserting rod 34 is driven to move downward, the second inserting rod 34 is inserted into the corresponding inserting hole 33 at the moment, the inner part of the shifting block 36 with the fourth groove 35 is in rotating connection, so the influence cannot be caused during descending, when the second inserting rod 34 moves upward, the shifting block 36 pushes against the front end of the cross rod 31, the cross rod 31 moves backward, the cross rod 31 moves forward under the action of the fourth spring 28, so that the cross rod 31 repeatedly moves forward and backward, the vibrating block 32 is driven to move forward and backward, so that one side of the lower mold 4 is beaten, thereby preventing the forging from sinking into the lower mold 4, thereby making the demolding easier, and when the connecting rod 705 moves to the moving position, there is an effect of the first screw thread 37 and the second screw thread 38, the support rod 708 rotates, and the support rod 708 rotates to drive the top block 709 to rotate, thereby making the descaling effect better.
