[0003] After searching the patent document with the publication number CN220636197U, the patent document discloses "a forging device for manufacturing mechanical parts, which can push out the support plate, the mounting plate and the clamping plate by rotating the threaded rod, so that the clamping plate can be close to the forging part, thereby preventing the forging part from being offset and falling when the forging table drives the forging part to rotate, thereby improving the forging stability and the safety of the operation";
[0004] When forging parts, the heated parts are prone to deformation. If the pressing die is small or the part structure is large after forging, the middle part of the part is easily squeezed to its two ends. Therefore, the position of the parts needs to be adjusted during forging so that the forging position can forge the edge of the parts. The position of the forging table of the above-mentioned device is fixed. Although the device can drive the forging table to rotate, the forging position is fixed, which can easily lead to the situation that the parts are thinner in the middle and thicker on the outside during forging.

[0028] The loading mechanism includes a sliding frame 3, which is slidably connected to the inside of the loading thick plate 2. A rotating shaft 31 is rotatably connected in the middle of the sliding frame 3. The rotating shaft 31 is divided into two sections. The diameter of the upper section of the rotating shaft 31 is smaller than the diameter of the lower end of the rotating shaft 31. The lower end surface of the top plate of the sliding frame 3 fits with the annular surface leaked from the lower section of the rotating shaft 31. A first gear 32 is fixed to the bottom of the rotating shaft 31. A motor 33 is provided on one side of the rotating shaft 31, and the housing of the motor 33 is fixed to the inner wall of the upper end of the sliding frame 3. The motor 33 outputs A second gear 34 is fixed to the output end, and the second gear 34 meshes with the first gear 32. A loading plate 35 is fixed to the upper end of the rotating shaft 31. The lower end surface of the loading plate 35 is in contact with the upper end surface of the rotating shaft 31. A mold 36 is provided at the upper end of the loading plate 35. A plurality of connecting bolts 37 are provided on the periphery of the mold 36. The bottom shape of the mold 36 corresponds to the loading plate 35. The mold 36 is fixed to the loading plate 35 by the connecting bolts 37. A pull rod 38 is fixed to the front end of the sliding frame 3. The length of 38 is the same as that of the sliding frame 3, and both ends of the pull rod 38 are fixed with stabilizing strips; when this device is in operation, the heated parts are placed in the mold 36, and then forged through the operating mechanism. During the forging process, the motor 33 is started, and the second gear 34 is meshed with the first gear 32. When the motor 33 drives the second gear 34 to rotate, the rotating shaft 31 in the middle of the first gear 32 can rotate in the opposite direction, thereby rotating the parts in the mold 36. Then, according to the forging situation, when the middle is thinner and the outer periphery is thicker during the forging process, the pull rod 38 is pulled to make the outer ring of the parts in the mold 36 located at the forging position, and the outer ring of the parts can be forged by cooperating with the mold 36 to drive the rotation of the parts. By adjusting the position of the parts in this way, the situation that the parts are thinner in the middle and thicker on the outer periphery after forging can be avoided, and the device can also unscrew the connecting bolts 37 as needed, so that the device can replace the corresponding appropriate mold 36.

When the device is operating, the pressing block 44 at the lower end of the mounting plate 43 is driven down by the pressing device 42, so that the device can forge the heated parts in the mold 36.
[0030] Working principle: When the device is in operation, the heated parts are placed in the die 36, and then the pressing device 42 drives the pressure block 44 at the lower end of the mounting plate 43 to descend, so that the device can forge the heated parts in the die 36. During the forging process, the motor 33 is started, and the second gear 34 is meshed with the first gear 32. When the motor 33 drives the second gear 34 to rotate, the rotating shaft 31 in the middle of the first gear 32 can rotate in the opposite direction, so that the parts in the die 36 rotate. Then, according to the forging situation, when the middle is thinner and the outer periphery is thicker during the forging process, the pull rod 38 is pulled to make the outer ring of the parts in the die 36 located in the forging position, and the outer ring of the parts can be forged by cooperating with the die 36 to drive the rotation of the parts. By adjusting the position of the parts in this way, the situation that the parts are thinner in the middle and thicker on the outer periphery after forging can be avoided.
