Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a high-strength gear forging device, including a base 1, a forging table 2, a first hydraulic rod 3, a connecting plate 4, a receiving plate 5, a first electric telescopic rod 6, a movable block 7, a rear clamping plate 8, a front clamping plate 9, a limiting rod 10, an anti-detachment plate 11, a gear block 12, a rack 13, a fixing plate 14, a second electric telescopic rod 15, a support plate 16, a forging hammer 17, a second hydraulic rod 18, a surrounding plate 19, a liquid inlet pipe 20, a pump 21, a liquid outlet pipe 22, a liquid return pipe 23, and a controller 24. The forging table 2 and the forging hammer 17 are sequentially arranged on the upper right side of the base 1, and the connecting plate 4 and the support plate 16 are respectively fixedly connected to the upper left side and the upper right front side of the base 1. The first hydraulic rod 3, fixed under the forging table 2, is embedded and installed on the inner right side of the base 1, and a clamping device located above the left side of the base 1 is provided on the upper side of the forging table 2. The clamping and fixing structure includes a tilting adjustment structure located on the left side of the connecting plate 4. The forging hammer 17 is equipped with a cooling structure located at the upper front end of the support plate 16. The second hydraulic rod 18, which is fixed to the forging hammer 17, is embedded and installed on the inner side of the middle rear end of the support plate 16. The clamping and fixing structure includes a receiving plate 5, a first electric telescopic rod 6, a movable block 7, a rear clamping plate 8, a front clamping plate 9, a limiting rod 10, and an anti-detachment plate 11. The receiving plate 5 is engaged and connected to the inner side of the middle of the connecting plate 4. The tilting adjustment structure includes a gear block 12, a rack 13, a fixing plate 14, and a second electric telescopic rod 15. The gear block 12 is fixedly connected to the left side of the receiving plate 5. The cooling structure includes a surrounding plate 19, a liquid inlet pipe 20, a pump 21, a liquid outlet pipe 22, and a liquid return pipe 23. The surrounding plate 19 is fixedly connected to the upper front end of the support plate 16.

[0028] To address the problems in existing technologies, such as the inconvenience of supporting and clamping the gear blank to be forged, the difficulty of flipping the gear blank for re-forging, and the reduced service life of the forging hammer 17 due to excessive temperature, this embodiment employs the following technical solution: Figure 1 and Figure 2 First, the gear blank to be forged can be placed on the upper right side of the forging platform 2, which is located in the middle of the upper part of the base 1. The forging platform 2 supports the gear blank. Then, the controller 24, which is embedded in the inner side of the upper rear end of the base 1, controls the first electric telescopic rod 6, which is fixed to the receiving plate 5 by clamps and screws, to operate. This causes the first electric telescopic rod 6 to drive the movable block 7, which is fixedly connected to its right side, to move on the receiving plate 5. Since the movable block 7 is rotatably connected to the staggered rear clamping plate 8 and the front clamping plate 8, the mechanism is designed to be flexible and adaptable. The clamping plate 9, the rear clamping plate 8, and the front clamping plate 9 are internally engaged with limiting rods 10 that are symmetrically fixed to the receiving plate 5. Therefore, through the operation of the first electric telescopic rod 6, the movable block 7 can drive the rear clamping plate 8 and the front clamping plate 9 to move under the limitation of the limiting rods 10, so that the right ends of the rear clamping plate 8 and the front clamping plate 9 can move inward until the anti-detachment plate 11 that is pasted and fixed on the outer side of the right end of the rear clamping plate 8 and the front clamping plate 9 is tightly attached and connected to the gear blank, thereby facilitating the purpose of clamping and fixing the gear blank to be forged.

[0029] like Figure 1 , Figure 2 and Figure 4 Then, the second hydraulic rod 18, which is embedded in the inner side of the rear end of the support plate 16, can be controlled by the controller 24 to perform the operation, so that the second hydraulic rod 18 drives the forging hammer 17 fixed below it to move down. Since the support plate 16 located in front of the forging table 2 is fixedly connected to the upper right front end of the base 1, and the forging hammer 17 is located above the middle of the forging table 2, the operation of the second hydraulic rod 18 makes it easy for the forging hammer 17 to hammer and forge the gear blank clamped and fixed on the forging table 2.

[0030] During the hammering and forging process, the controller 24 can control the operation of the first hydraulic rod 3, which is embedded in the base 1 under the forging table 2, so that the forging table 2 fits against the base 1. Then, the controller 24 can control the operation of the second electric telescopic rod 15, which is fixedly installed on the inner side of the lower front end of the rack 13 and the fixed plate 14, so that the second electric telescopic rod 15 drives the rack 13 to move under the contact limit of the fixed plate 14. Since the rack 13 is meshed with a gear block 12, the gear block 12 is located on the left side of the fixed connecting plate 4 on the upper left side of the base 1. Furthermore, the right side of the gear block 12 is fixedly connected to a receiving plate 5 that engages with the connecting plate 4. Therefore, by operating the second electric telescopic rod 15, the rack 13 can drive the gear block 12 to rotate, causing the gear block 12 to drive the receiving plate 5 to rotate within the connecting plate 4. This achieves the purpose of flipping the gear blank clamped and fixed on the right side of the receiving plate 5. Then, the controller 24 can control the first hydraulic rod 3 to operate again, causing the forging table 2 to adhere to the gear blank and support it, so that the gear can be hammered and forged again to achieve high strength.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 During the forging process by the forging hammer 17, the pump 21, which is fixedly installed on the support plate 16 by screws, can be controlled by the controller 24. Since a surrounding plate 19 is fixedly connected to the upper front side of the support plate 16, a liquid-passing pipe 20 is threadedly connected to the inner side of the forging hammer 17 and the surrounding plate 19, and a liquid-drawing pipe 22 is threadedly connected to the inner side of the pump 21. The liquid-passing pipe 20 and the liquid-drawing pipe 22 are respectively engaged and pass through the inner side of the left and right rear ends of the support plate 16, and the pump 21 is also engaged on the inner side of its left end. The threaded connection has a return pipe 23 that communicates with the enclosure plate 19. Therefore, by operating the pump 21, the coolant in the forging hammer 17 can be easily passed through the pumping pipe 22 to the enclosure plate 19 via the return pipe 23. This allows the coolant in the enclosure plate 19 to flow back into the forging hammer 17 via the liquid flow pipe 20, achieving the purpose of circulating the coolant within the forging hammer 17. This facilitates the cooling of the forging hammer 17 and prevents its service life from being affected by excessive temperature. All the electrical components mentioned above are existing technologies and will not be described in detail here.
