The top and bottom ends of the mounting cylinder 53 are both penetrated by connecting grooves 54, and the connecting grooves 54 are distributed in an array, and a third rotating rod 55 is rotatably inserted on the mounting cylinder 53, and a fixing ring 56 is fixedly sleeved on the third rotating rod 55, and an array-distributed driving fan blade 57 is fixedly installed on the outer wall of the fixing ring 56, and a third bevel gear is fixedly sleeved on the end of the third rotating rod 55 away from the fixing ring 56 58, a fourth rotating rod 59 is rotatably inserted on the preheating box 51, a symmetrically arranged first through-hole 515 is opened on the partition carrier 52, and the mounting cylinder 53 is fixedly inserted in the first through-hole 515, a symmetrically distributed second through-hole 516 is opened on the preheating box 51, and the fourth rotating rod 59 is rotatably inserted in the second through-hole 516, and two fourth bevel gears 510 are fixedly sleeved on the fourth rotating rod 59, and the fourth bevel gear 510 is meshed with the third bevel gear 58, the driving mechanism 6 includes a mounting base 61, the mounting base 61 is fixedly connected to the collecting hopper body 31, and a driving motor 62 is fixedly inserted in the mounting base 61. In this solution: the driving motor 62 is preferably Y80M1-2 model, the power supply interface of the motor is connected to the power supply system through a switch, the operating circuit of the drive motor 62 is a conventional drive motor 62 forward and reverse control program, the circuit operation is an existing conventional circuit, the circuits and controls involved in this scheme are all existing technologies, and will not be elaborated on here.

[0033] By adopting the above technical solution, the driving motor 62 will drive the fifth bevel gear 63 to rotate, thereby driving the sixth bevel gear 64 and the seventh bevel gear 65 to rotate, and when the seventh bevel gear 65 rotates, it will drive the fourth rotating rod 59 to rotate, thereby driving the two fourth bevel gears 510 to rotate, and then driving the corresponding third bevel gear 58 to rotate, and when the third bevel gear 58 rotates, it will drive the corresponding third rotating rod 55 to rotate, thereby driving the corresponding driving fan blade 57 to rotate through the fixing ring 56, and then the outside air can be sucked into the bottom of the inner cavity of the preheating box 51 through the first air inlet slot 11 and the second air inlet slot 511. At this time, the cold air can absorb the residual heat on the turbine rotor forging after forging, and then the heat-absorbing air will be introduced into the upper end of the inner cavity of the preheating box 51 through the corresponding two connecting through-slots 54, and then the heat-absorbing air can preheat the forged turbine rotor forging to be heated placed on the partition carrier 52, and then the heat-released air will be discharged from the air outlet through-hole 512.

[0034] Working principle: The user can open the blocking plate 514 and place an appropriate amount of steam turbine rotor forgings to be heated at high temperature on the partition carrier 52. Then, the user can move any steam turbine rotor forging that has been heated at high temperature to the forging table body 21 and perform forging operation through the forging machine body 2. During this period, the steam turbine rotor forging being forged will drop oxide scale debris on the top of the forging table body 21. When the forging operation of the corresponding steam turbine rotor forging is completed, the user can place the forged steam turbine rotor forging at the bottom of the inner cavity of the preheating box 51. Then, the user can reset the blocking plate 514 and turn on the multi-stage electric push rod 42 and the drive motor 62.

[0035] Subsequently, the multi-stage electric push rod 42 will drive the cleaning scraper 43 to make a reciprocating motion, thereby being able to push the oxide scale debris dropped from the top of the forging table body 21 into the collecting hopper body 31, and when the cleaning scraper 43 makes a reciprocating motion, the multi-stage electric push rod 42 will pause, and then the user can perform subsequent high-temperature heating of the steam turbine rotor forging according to the above steps and place the forged steam turbine rotor forgings in sequence at the bottom of the inner cavity of the preheating box 51, and the oxide scale debris dropped after forging can be cleaned in sequence by the cleaning scraper 43, without the user having to manually clean it multiple times, thereby saving manpower;

[0036] During this period, the driving motor 62 will drive the fifth bevel gear 63 to rotate, thereby driving the sixth bevel gear 64 and the seventh bevel gear 65 to rotate, and when the sixth bevel gear 64 rotates, it can drive the first rotating rod 32 to rotate, thereby driving the first bevel gear 33 to rotate, and then driving the second bevel gear 36 to rotate, and further driving the second rotating rod 35 to rotate, and when the second rotating rod 35 rotates, it can drive the driving gear 37 to rotate, thereby cooperating with the use of the rotating guide ring 314 and the rotating guide groove 315 to drive the rotating sleeve 38, the connecting side column 39 and the driving gear ring 310 to rotate, and then can drive the collecting scraper 312 to rotate through the connecting vertical rod 311, so that the oxide scale debris accumulated in the collecting hopper body 31 can be concentrated and discharged through the discharging perforation 313. At this time, the user can conveniently collect the oxide scale debris generated during the forging of the turbine rotor forging, without the need for the user to clean it up later, thereby further saving manpower;

[0037] And when the seventh bevel gear 65 rotates, it will drive the fourth rotating rod 59 to rotate, thereby driving the two fourth bevel gears 510 to rotate, and then driving the corresponding third bevel gear 58 to rotate. When the third bevel gear 58 rotates, it will drive the corresponding third rotating rod 55 to rotate, thereby driving the corresponding driving fan blade 57 to rotate through the fixed ring 56, and then the outside air can be sucked into the bottom of the inner cavity of the preheating box 51 through the first air inlet slot 11 and the second air inlet slot 511. At this time, the cold air can absorb the residual heat on the turbine rotor forging after forging, and then the heat-absorbing air will be introduced into the upper end of the inner cavity of the preheating box 51 through the corresponding two connecting through slots 54. Then the heat-absorbing air can preheat the turbine rotor forging to be heated placed on the partition carrier 52, and then the heat-released air will be discharged from the air outlet perforation 512. During subsequent use, the user can perform high-temperature heating and forging treatment on the preheated turbine rotor forging on the partition carrier 52.
