[0048] Then the driving part 422 is started to drive the sliding rods 421 to slide towards the flange, when the plurality of sliding rods 421 slide, the plurality of positioning rods 41 are driven to slide, during the sliding process of the positioning rod 41, the flange is pushed and slides to the center position of the forging and pressing table 2, during the sliding process of the positioning rod 41, the adjacent two telescopic parts 412 are pressed against each other, so that the telescopic part 412 slides into the fixed part 411 and compresses the elastic part 413;

[0049] When the position adjustment of the flange is completed, the forging mechanism 6 is started to forge and press the flange, during the forging and pressing process of the flange by the forging mechanism 6, the vibration generated can drive the telescopic part 342 to adjust the lifting, the telescopic part 342 can drive the blocking plate 341 to adjust the lifting, when the communication groove 343 on the blocking plate 341 communicates with the sand leakage groove 331, the sand in the storage box 33 can be laid on the protective plate 32 after passing through the communication groove 343 and the sand leakage groove 331, during the intermittent forging and pressing process of the flange by the forging mechanism 6, the sand can be intermittently conveyed, and the sand can be replaced in time, during the flange processing, the metal scraps flying are intercepted by the sand on the protective plate 32, and when a large amount of sand is used, the sand can pass through the blocking part 321 and fall between the positioning rod 41 and the protective frame 31;

[0050] ​When the flange forging and pressing process is completed, the driving member 422 is started, the sliding rod 421 is driven to slide away from the flange, the positioning rod 41 is driven to slide, and the sand falling between the positioning rod 41 and the protective frame 31 can be scraped in the sliding process of the positioning rod 41. At the same time, the elastic member 413 releases the elastic restoring force, and the telescopic part 412 slides out of the fixed part 411. When the telescopic part 412 slides to the linkage block 5, the positioning rod 41 continues to slide out of the platform body 1, and at the same time the power member drives the protective frame 31 to slide out of the platform body 1. The positioning rod 41 and the protective frame 31 slide in the process, push the used sand into the sand discharge groove 11, and discharge it through the sand discharge groove 11, and complete the forging and pressing work of the flange.

[0051] Through the setting of the protective device 3, the protective device 3 is provided along the four sides of the forging table 2, and the sealing assembly 34 can adjust the opening and closing of the sand leakage groove 331. When the flange on the forging table 2 needs to be forged, first adjust the sealing assembly 34 so that the sealing assembly 34 controls the sand leakage groove 331 to open. At this time, the sand in the storage box 33 can pass through the sand leakage groove 331 and be laid on the side of the protective plate 32 close to the forging table 2. At this time, when the metal scraps splash during the forging process of the flange, the splashed metal scraps can adhere to the sand on the protective plate 32. The splashed metal scraps are intercepted by the sand, which can avoid the problem that the splashed metal scraps adhere to the platform body 1, causing the subsequent support platform to be difficult to clean. At the same time, by replacing the used sand in time, the splashed metal scraps can be continuously intercepted, thereby realizing continuous and efficient processing of the flange.
