[0053] The transmission belt 19 is made of fire-resistant and high-temperature resistant material. The upper belt of the transmission belt 19 is located above the top surface of the forging table 1, and the lower belt of the transmission belt 19 slides through the forging table 1.

[0054] The rotating shaft 17 is connected to the movable seat 12 via the second transmission component.

[0055] Specifically, the second transmission component includes a rack 15 and a gear 16. The rack 15 is vertically positioned on the side of the forging table 1, and a connecting rod is fixedly installed between the top of the rack 15 and the movable seat 12. The gear 16 is fixedly sleeved on the rotating shaft 17. The rack 15 and the gear 16 mesh with each other.

[0056] It should be noted that, in this embodiment, in order to prevent the vibration of the forging table 1 from damaging the meshing of the gear 16 and rack 15, as well as the transmission of the first pulley 2, the second pulley 18, and the transmission belt 19 during the forging of the trunnion body forging, two independent forging tables 1 can be used. One table is used for forging and installing the scraper 3, and the other table is used for installing the linkage assembly and the clamping and flipping assembly.

[0057] Working Principle: When forging trunnion body forgings using this forging equipment, the trunnion body forging is first placed on the forging table 1, positioned between the top openings of the two grippers 8 and the two guide ramps 6. Next, the third hydraulic cylinder 25 is activated, extending its telescopic shaft and pushing the push rod 24 away from the turntable 11. During this process, the push rod 24 pushes the two push rings 20 away from the turntable 11, and the two push rings 20 push the hinged first hinge rod 21 to rotate away from the turntable 11. The two first hinge rods 21 push the hinged push rings 20 to slide closer to the telescopic shaft of the third hydraulic cylinder 25. Simultaneously, as the two push rings 20 slide closer to the telescopic shaft of the third hydraulic cylinder 25, they push the grippers 8 closer to the trunnion body forging via the hinged second hinge rod 23.

[0058] When the two grippers 8 contact and clamp the trunnion forging, the third hydraulic cylinder 25 is shut down. Then, the first hydraulic cylinder 10 is activated, its telescopic shaft extending downwards and pushing the hammer 9 to strike the trunnion forging. The first hydraulic cylinder 10 can be replaced with a suitable power source such as a pneumatic cylinder, depending on the actual production situation.

[0059] When it is necessary to flip the trunnion body forging, the first hydraulic cylinder 10 is shut down and the second hydraulic cylinder 13 is started. The telescopic shaft of the second hydraulic cylinder 13 extends upward and pushes the movable seat 12 upward. At this time, the movable seat 12 drives the turntable 11, the turntable 11 drives the mounting bracket 22, the mounting bracket 22 drives the two slide rods, the two slide rods drive the two grippers 8, and the two grippers 8 lift the trunnion body forging upward to a certain height.

[0060] Next, motor 14 is started. The output shaft of motor 14 drives a disc, which drives a rotating drum, which drives a turntable 11. Turntable 11 drives a mounting bracket 22, which drives two sliding rods. The two sliding rods drive two grippers 8, which in turn rotate the trunnion body forging 180 degrees. At this time, motor 14 is turned off, and the telescopic shaft of the second hydraulic cylinder 13 retracts downward, causing the movable seat 12 to move downward. During this process, the movable seat 12 drives the turntable 11, which drives the mounting bracket 22. The mounting bracket 22 drives the two sliding rods, which in turn drive the two grippers 8, which in turn cause the trunnion body forging to fall back onto the forging table 1.

[0061] After the trunnion body forging falls back onto the forging table 1, the first hydraulic cylinder 10 is started again to make the hammer head 9 strike the trunnion body forging.

[0062] As the movable seat 12 moves upward, it drives the rack 15 upward via the connecting rod. The rack 15 pushes the gear 16 to rotate, and the gear 16 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the second pulley 18 to rotate, and the second pulley 18 drives the first pulley 2 to rotate via the transmission belt 19. When the second transmission belt 19 is in operation, it drives the scraper 3 to push the debris on the top surface of the forging table 1 into the guide ramp 6, and the debris flows to the collection box 4 through the guide ramp 6.

[0063] As the movable seat 12 moves downward, it drives the rack 15 downward via the connecting rod. The rack 15 pushes the gear 16 to reverse, and the gear 16 drives the rotating shaft 17 to reverse. The rotating shaft 17 drives the second pulley 18 to reverse, and the second pulley 18 drives the first pulley 2 to reverse via the transmission belt 19. When the second transmission belt 19 is in operation, it causes the scraper 3 to slide back.

[0064] When the scraper 3 slides along the top surface of the forging table 1, it does not interfere with the up-and-down movement of the trunnion forging.

[0065] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
