at the moment, the centrifugal main magnet 50 can adsorb the centrifugal auxiliary magnet 48 to move rightwards, the centrifugal auxiliary magnet 48 moves rightwards to drive the end face gear 47 to move rightwards through the sliding block 42 and to be meshed with the centrifugal transmission gear 54, the centrifugal transmission gear 54 rotates to drive the end face gear shaft 43 to rotate through the end face gear 47, the end face gear shaft 43 rotates to drive the gear annular rack 23 to rotate through the transmission gear 32, the gear annular rack 23 rotates to drive the hammering rack 17 to move upwards through the half rack gear 20, the hammering rack 17 moves upwards to drive the hammering column 21 to move upwards by overcoming the thrust of the hammering spring 25, when the half rack gear 20 is disengaged from the hammering rack 17, the hammering column 21 moves downwards under the elastic force of the hammering spring 25 and the self gravity, and the purpose of hammering a forged workpiece is achieved;

when the temperature of the forged workpiece is gradually reduced, the forging effect of the forged workpiece is reduced, at the moment, the liquid in the liquid-shaped variable cavity 74 drives the magnetic sealing block 73 to move leftwards, at the moment, the magnetic sealing block 73 drives the rheostatic shifting fork 69 to move leftwards through the auxiliary magnetic block 72, so that the available resistance on the rheostatic 68 is gradually increased, the voltage on the servo motor 18 is gradually reduced, the rotating speed of the servo motor 18 is gradually reduced, when the magnetic sealing block 73 does not adsorb the auxiliary magnet 75 to loosen the limiting wheel pull rope 77, the main limiting wheel 79 moves rightwards under the thrust action of the limiting wheel spring 78 to be meshed with the auxiliary limiting wheel 81;

when the temperature of the forging workpiece is reduced to the extent that the centrifugal main magnet 50 cannot stretch out against the pulling force of the centrifugal magnet spring 51, the centrifugal main magnet 50 does not adsorb the centrifugal auxiliary magnet 48, the sliding block 42 is reset under the pulling force of the sliding spring 45, the auxiliary magnetic block 72 just contacts with the contact block 12 at the moment, the contact block 12 sends a signal, the electromagnet 66 is automatically powered off within a certain time after being powered on, the repulsion magnet 65 drives the transposition transmission gear 57 to move leftwards through the transposition shaft 55 to be disengaged from the transmission spur gear 31 and to be engaged with the transmission half gear 60, at the moment, the transposition transmission gear 57 drives the main wire wheel 27 to rotate through the transmission half gear 60, the main wire wheel 27 rotates through the wire wheel pull rope 29 to pull the auxiliary wire wheel 84 to rotate, the auxiliary wire wheel 84 rotates through the auxiliary wire wheel shaft 82 to drive the auxiliary wire wheel gear 40 to rotate, the auxiliary wire wheel gear 40 rotates through the rack gear 38 to drive the rack gear, at the moment, the secondary limiting wheel 81 rotates and is limited by the main limiting wheel 79, meanwhile, the electromagnetic heater 15 is driven to move upwards through the heating rack 14, when the electromagnetic heater 15 moves upwards until the heating rack 14 is disengaged from the rack gear 38, the transposition transmission gear 57 is just disengaged from the transmission half gear 60, at the moment, the electromagnetic heater 15 starts to work, and the forging workpiece is heated through electromagnetic induction;

when the temperature of a forging workpiece rises, the magnetic sealing block 73 adsorbs the auxiliary magnetic block 72 to drive the rheostatic shifting fork 69 to move rightwards, when the rheostatic shifting fork 69 moves to the minimum resistance, the magnetic sealing block 73 adsorbs the auxiliary magnet 75 to move leftwards, the auxiliary magnet 75 pulls the magnet 65 through the magnet pull rope 67 to drive the transposition transmission gear 57 to move rightwards through the transposition shaft 55 to be disengaged from the transmission half gear 60 and be engaged with the transmission straight gear 31, so that the hammering column 21 continues to do hammering movement, meanwhile, the auxiliary magnet 75 moves leftwards through the limit wheel pull rope 77 to pull the main limit wheel 79 to move leftwards to be disengaged from the limit wheel 81 by overcoming the thrust of the limit wheel spring 78, and at the moment, the electromagnetic heater 15 moves downwards to reset under the torsion action of the torsion spring 36.

The invention has the beneficial effects that: this device is through the thermal conductivity of heat conduction piece and the expend with heat and contract with cold of liquid deformation intracavity, monitor the current temperature of forging the work piece, because rheostat and servo motor establish ties, through the available resistance on the rheostat of varistor shift fork control, make it follow the change of the temperature of forging the work piece and change, then control servo motor's voltage signal through the partial pressure, make servo motor's rotational speed changeable, whether rethread centrifugation main magnet is thrown away because of the effect of centrifugal force, whether control hammering rack carries out work under higher temperature, make the forging work piece only carry out high efficiency forging, when the temperature is low excessively, can directly carry out electromagnetic heating through electromagnetic heater to the forging work piece, the loaded down with trivial details of artifical transport has been avoided, the labour has been practiced thrift.
