Special steel forgings need to be combined forged by different dies during forging forming. First, pre-forging is performed: the preliminary shaping of the blank is completed in the first set of dies, and internal defects are eliminated by upsetting and extrusion. Then, transition shaping is performed: the pre-forging part is locally corrected in the second set of dies. Finally, finish forging is performed: the workpiece shaping is completed in the third set of dies to control the final size.

[0035] Reference Figures 1 to 4When the workpiece is forged, the motor shaft of the second servo motor 20 drives the first gear 21 to rotate, drives the meshed gear disc 22 to rotate, drives the rotating column 2 to drive the first mounting bracket 3 and the second mounting bracket 4 to rotate synchronously, drives the upper die 6 and the lower die 5 of the pre-forging die to be located below the forging machine body 8, drives the rotating shaft 14 to rotate by the first servo motor 7, so that the lower die 5 with the opening downward is turned over to the upper side, and the lower end of the lower die 5 is abutted on the surface of the first mounting bracket 3, thereby limiting the lower die 5, reducing the deformation of the rotating shaft 14, the workpiece heated at high temperature is placed in the lower die 5 by the mechanical hand, the piston rod of the forging machine body 8 extends downward and is abutted on the guide column 13, thereby exerting pressure, the first spring 131 stores energy, drives the guide column 13 to drive the upper die 6 to be abutted on the lower die 5, so that the workpiece completes the preliminary forming of the blank in the die cavity, the workpiece preliminarily formed is taken out from the lower die 5 by the mechanical hand, after the pre-forging die is forged, the sizing die is turned to the lower side of the forging machine body 8, and the pre-forged workpiece is locally corrected, after the workpiece is sized, the final-forging die is turned to the lower side of the forging machine body 8, and the workpiece is finally forged, the final size control is completed, so that the workpiece can sequentially complete the pre-forging, sizing and final-forging treatment in the same device, the time of process connection is reduced, and the temperature difference of the workpiece is reduced, so that the forging quality and efficiency of the workpiece can be improved.

[0036] In order to improve the forging quality of the mold, the impurities on the mold need to be cleaned. When the lower mold of the pre-forging works, the angle of the shaping lower mold 5 and the final forming lower mold 5 is adjusted by the first servo motor 7, so that the opening is downward, so that the impurities with large internal volume can be poured into the annular collecting groove 19, reducing the impurities in the lower mold 5, and then the horizontal moving position of the base 25 is adjusted by the electric sliding table 24 installed on the first mounting bracket 3, so that the collecting plate 27 on the base 25 moves to the lower side of the upper mold 6, which is used to recover the impurities falling from the upper mold 6, avoid the impurities falling on the surface of the first mounting bracket 3, reduce the influence of the impurities on the lower mold 5 when the lower mold 5 rotates to reset, affect the clamping of the lower mold 5 and the upper mold 6, when the piston rod of the forging machine main body 8 moves downward, the pressing plate 39 moves downward synchronously, so that the pressing plate 39 can contact the two wave-shaped contact strips 10 corresponding to the two lower molds 5, and push the two wave-shaped contact strips 10 to move downward on the first mounting bracket 3 and the second mounting bracket 4 synchronously, the third spring 18 is charged, the wave-shaped contact strip 10 corresponding to the pre-forging lower mold 5 does not contact the pressing plate 39, preventing the influence on the mold being forged, when the wave-shaped contact strip 10 moves downward and contacts the plurality of contact rods 16, the contact rod 16 drives the impact block 9 to reciprocate horizontally on the first mounting bracket 3 and the second mounting bracket 4, thereby continuously and automatically knocking the lower mold 5 and the upper mold 6 which are not working in other processes, so that the impurities adhered to the lower mold 5 and the upper mold 6 can fall on the annular collecting groove 19 and the collecting plate 27 respectively, thereby reducing the impurities on the non-working upper mold 6 and lower mold 5, and improving the precision and quality of the subsequent forging of the workpiece.

[0037] In the embodiment, the first mounting bracket 3 and the second mounting bracket 4 are improved on the basis of the first embodiment, and the specific improvement is described with reference to Figures 1 to 9 The two hollow pipes 29 are rotatably connected to the V-shaped cleaning seat 11, the upper end of the adsorption cover 12 is fixedly connected to the hollow pipe 29, the V-shaped filter plate 30 is fixedly connected to the upper end of the adsorption cover 12, and the lower end of the hollow pipe 29 is provided with the rotary joint 31.

[0038] The vertical plate 32 is fixedly connected to the bottom plate 1, the electric push rod 33 is fixedly connected to the vertical plate 32, the piston rod of the electric push rod 33 is elastically connected to the V-shaped cleaning seat 11 through the fourth spring 35, the guide rod 34 is fixedly connected to the vertical plate 32, and the guide rod 34 is slidably connected to the vertical plate 32.

[0039] The second gear 26 is fixedly connected to the hollow pipe 29, the rack 36 is meshingly connected to the second gear 26, the rack 36 is elastically connected to the V-shaped cleaning seat 11 through the fifth spring 37, the contact strip 38 is fixedly connected to the contact rod 16, the scraper 47 is fixedly connected to the hollow pipe 29, and the V-shaped cleaning seat 11 is provided with the impurity discharge port 48.

[0040] Reference Figures 1 to 9In order to further improve the cleaning effect of the mold, after the deflection of the first mounting bracket 3 and the second mounting bracket 4 is completed, when the piston rod of the electric push rod 33 is extended, the 匚-shaped cleaning seat 11 can be driven to move horizontally to the lower mold 5 and the upper mold 6 corresponding to the next process. At this time, the 匚-shaped cleaning seat 11 is pressed against the first mounting bracket 3 and stops. The rotary joint 31 installed at the lower end of the hollow tube 29 is connected to the dust collection equipment, which enables the negative pressure to flow into the two adsorption hoods 12, so that the air around the upper mold 6 and the lower mold 5 carries dust and small debris into the adsorption hood 12 under the action of the pressure difference, which can achieve the purpose of adsorbing and cleaning the impurities of the upper mold 6 and the lower mold 5, and can reduce the damage to the workpiece during the forging process. In order to avoid the influence of impurities and improve the quality of forging, when the resistance rod 16 drives the impact block 9 to move horizontally for knocking, it can drive the resistance bar 38 to move synchronously, prompting the resistance bar 38 to push the rack 36 to move horizontally in the 匚-shaped cleaning seat 11, and the fifth spring 37 accumulates force, prompting the rack 36 to drive the second gear 26 to rotate, prompting the hollow tube 29 and the adsorption cover 12 to rotate in a circle when adsorbing impurities, thereby reducing the dead angle of impurity adsorption and greatly improving the cleaning effect of the upper mold 6 and the lower mold 5. At the same time, the scraper 47 fixed on the hollow tube 29 can rotate synchronously with the adsorption cover 12, and can scrape the impurities fallen on the 匚-shaped cleaning seat 11 into the impurity discharge port 48 for discharge, which is convenient for the recovery and treatment of impurities on the 匚-shaped cleaning seat 11.

[0041] Example 3: This example is an improvement made on the basis of Example 2.

An L-shaped contact strip 44 is fixed to one end of the contact head 42, and several arc-shaped contact blocks 45 are fixed to one side of the rack 36.

[0043] refer to Figures 1 to 9 When there are too many impurities collected on the collecting plate 27, the collecting plate 27 will be scattered onto the surface of the first mounting bracket 3 when it rotates horizontally, affecting the accuracy of the rotation and reset of the lower mold 5. It is necessary to clean the impurities on the collecting plate 27 in time. When the piston rod of the electric push rod 33 continues to extend, it can drive the contact wedge 40 to contact the collecting plate 27. The fourth spring 35 accumulates force, prompting the collecting plate 27 to rotate on the rotating rod 46 of the base 25. The torsion spring 28 accumulates force, and the collecting plate 27 is in an inclined state, which facilitates the impurities to automatically slide into the annular collecting groove 19. Meanwhile, in order to further improve the effect of cleaning the impurities on the collecting plate 27, when the rack 36 is retracted into the inside of the L-shaped cleaning seat 11, the arc-shaped abutting blocks 45 and the L-shaped abutting strips 44 are intermittently abutted, the abutting head 42 reciprocates on the second mounting block 41, the sixth spring 43 is continuously charged and released, the abutting head 42 and the collecting plate 27 reciprocate, the collecting plate 27 continuously swings within a certain range, and the effect of cleaning the impurities is greatly improved.
