[0018] The beneficial effects of the present invention are: 1. In the present invention, through the setting of the protective device, multiple protective devices are arranged along the four sides of the forging table, and the sealing assembly can adjust the opening and closing of the sand leakage trough. When the flange on the forging table needs to be forged, the sealing assembly is first adjusted to make the sealing assembly control the sand leakage trough to open. At this time, the sand in the storage box can pass through the sand leakage trough and be laid on the side of the protective plate close to the forging table.

The storage box 33 is provided with a sand leakage groove 331 connected to the gap between the two adjacent protective plates 32. The sand leakage groove 331 is a rectangular groove. There are multiple sand leakage grooves 331 spaced and evenly arranged in the vertical direction. The sand leakage groove 331 corresponds to the gap between the two adjacent protective plates 32.

[0039] Reference Figure 3 、 Figure 4 and Figure 6 The blocking component 34 is set in the storage box 33 and is used to control the opening and closing of the sand leakage groove 331. When the blocking component 34 controls the sand leakage groove 331 to open, sand 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. When the blocking component 34 controls the sand leakage groove 331 to close, the sand is blocked in the storage box 33 and cannot flow through the sand leakage groove 331. Figure 7The blocking assembly 34 includes a blocking plate 341 for controlling the opening and closing of the sand leakage groove 331 and a telescopic member 342 for driving the blocking plate 341 to move. The blocking plate 341 is a rectangular plate. The blocking plate 341 slides in the vertical direction to fit in the storage box 33. The blocking plate 341 is provided with a connecting groove 343 that is adapted to the sand leakage groove 331. The connecting groove 343 is a rectangular groove.

[0040] Reference Figure 1 、 Figure 3 and Figure 4 , start the forging mechanism 6. During the forging process of the flange by the forging mechanism 6, the vibration generated can drive the telescopic part 342 to be raised and lowered, and the telescopic part 342 can drive the sealing plate 341 to be raised and lowered. When the connecting groove 343 on the sealing plate 341 is connected with the sand leakage groove 331, the sand in the storage box 33 can pass through the connecting groove 343 and the sand leakage groove 331 and be laid on the protective plate 32. During the intermittent forging of the flange by the forging mechanism 6, the sand can be transported at intervals and the sand can be replaced in time. During the flange processing, the sand on the protective plate 32 can intercept the flying metal debris. At the same time, when a large amount of sand is used, the sand can pass over the blocking part 321 and fall between the positioning rod 41 and the protective frame 31.

[0041] Reference Figure 3 、 Figure 4 and Figure 5 , multiple protective frames 31 are provided with positioning devices 4, which are used to push the flange to move to the center of the forging platform 2. The positioning device 4 includes a positioning rod 41 for pushing the flange to move to the center of the forging platform 2 and a driving assembly 42 for driving the positioning rod 41 to move. The positioning rod 41 slides in the horizontal direction and fits the platform body 1. Figure 9The positioning rod 41 includes a fixed portion 411, a telescopic portion 412 that slides on the fixed portion 411, and an elastic member 413 for driving the telescopic portion 412 to slide to the outside of the fixed portion 411.

The elastic member 413 directly adopts a spring, one end of the elastic member 413 is fixedly connected to the telescopic portion 412, and the other end of the elastic member 413 is fixedly connected to the fixed portion 411. In the initial state, the elastic member 413 drives the telescopic portion 412 to slide to the outside of the fixed portion 411 and is set in an expanded state; when the multiple positioning rods 41 slide in a direction approaching each other, the flange can be pushed and the flange can slide toward the center position of the forging table 2. During the sliding process of the positioning rod 41, the two adjacent telescopic portions 412 squeeze each other, causing the telescopic portion 412 to slide into the fixed portion 411 and compress the elastic member 413.

[0042] Among them, reference Figure 3 、 Figure 4 and Figure 5 The driving assembly 42 includes a sliding rod 421 fixedly connected to the fixing portion 411 and a driving member 422 for driving the sliding rod 421 to slide. Figure 10 The driving member 422 directly adopts a cylinder, one end of the driving member 422 is fixedly connected to the platform body 1, and the other end is fixedly connected to the sliding rod 421, and the driving member 422 slides with the storage box 33; starting the driving member 422 can drive the sliding rod 421 to slide, and then drive the fixed part 411 to slide and adjust.

[0043] Reference Figure 3 、 Figure 4 and Figure 5 , start the driving part 422, drive the sliding rod 421 to slide in the direction away from the flange, drive the positioning rod 41 to slide, and during the sliding process of the positioning rod 41, the sand that falls between the positioning rod 41 and the protective frame 31 can be scraped off. At the same time, the elastic part 413 releases the elastic restoring force, driving the telescopic part 412 to slide toward the outside of the fixed part 411. When the telescopic part 412 slides to the linkage block 5, the positioning rod 41 continues to slide toward the outside of the platform body 1. At the same time, the power part drives the protective frame 31 to slide toward the outside of the platform body 1. During the sliding process of the positioning rod 41 and the protective frame 31, the used sand is pushed into the sand discharge trough 11 and discharged through the sand discharge trough 11.

[0044] Reference Figure 3 、 Figure 4 and Figure 5A linkage block 5 is fixedly mounted on the protective frame 31, corresponding to one end of the positioning rod 41. The linkage block 5 is a rectangular block and is located at the bottom of the protective frame 31. When the positioning rod 41 is in the expanded state, the end of the telescopic portion 412 away from the fixed portion 411 is horizontally aligned with the linkage block 5. The platform body 1 is provided with a sand discharge chute 11 for draining sand. The chute 11 is arranged downwardly and tilted away from the protective frame 31. When the driving member 422 drives the positioning rod 41 to slide toward the outside of the platform body 1 and the positioning rod 41 slides to the linkage block 5, the protective frame 31 simultaneously slides toward the outside of the platform body 1.

[0045] The implementation principle of the flange forging support device of the present invention is as follows: when the flange needs to be forged, the flange is first placed on the forging table 2, and then the power unit is started to drive the forging table 2 to descend and slide into the chamber formed by the four protective devices 3, and then the rotating mechanism is started, and the rotating mechanism can drive the multiple protective plates 32 to rotate in the horizontal direction, so that the multiple protective plates 32 are tilted (the state is as shown in FIG. Figure 3 Figure 4 Figure 5 Figure 3 shown); Then, the driving member 422 is started to drive the sliding rod 421 to slide toward the flange. When the multiple sliding rods 421 slide, they can drive the multiple positioning rods 41 to slide. During the sliding process of the positioning rods 41, they can push the flange and make the flange slide toward the center position of the forging table 2. During the sliding process of the positioning rods 41, the two adjacent telescopic parts 412 squeeze each other, causing the telescopic parts 412 to slide into the fixed part 411 and compress the elastic member 413. When the position adjustment of the flange is completed, the forging mechanism 6 is started to forge the flange. During the forging process of the flange by the forging mechanism 6, the vibration generated can drive the telescopic member 342 to be raised and lowered, and the telescopic member 342 can drive the blocking plate 341 to be raised and lowered. When the connecting groove 343 on the blocking plate 341 is connected with the sand leakage groove 331, the sand in the storage box 33 can pass through the connecting groove 343 and the sand leakage groove 331 and be laid on the protective plate 32. During the intermittent forging process of the flange by the forging mechanism 6, the sand can be transported at intervals and the sand can be replaced in time. During the flange processing, the sand on the protective plate 32 can intercept the flying metal debris. At the same time, when a large amount of sand is used, the sand can pass over the blocking portion 321 and fall between the positioning rod 41 and the protective frame 31. When the flange forging process is completed, the driving part 422 is started to drive the sliding rod 421 to slide in the direction away from the flange, driving the positioning rod 41 to slide. During the sliding process of the positioning rod 41, the sand that falls between the positioning rod 41 and the protective frame 31 can be scraped. At the same time, the elastic part 413 releases the elastic restoring force, driving the telescopic part 412 to slide toward the outside of the fixed part 411. When the telescopic part 412 slides to the linkage block 5, the positioning rod 41 continues to slide toward the outside of the platform body 1. At the same time, the power part drives the protective frame 31 to slide toward the outside of the platform body 1. During the sliding process of the positioning rod 41 and the protective frame 31, the used sand is pushed into the sand discharge trough 11 and discharged through the sand discharge trough 11, completing the forging operation of the flange.

[0046] Through the setting of the protective device 3, multiple protective devices 3 are set along the four sides of the forging table 2, and the sealing component 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, the sealing component 34 is first adjusted to make the sealing component 34 control 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 flange is forging, when metal debris splashes, the splashed metal debris can adhere to the sand on the protective plate 32. The splashed metal debris can be intercepted by the sand, which can prevent the splashed metal debris from adhering to the platform body 1, resulting in the problem that the subsequent support platform is difficult to clean. At the same time, by replacing the used sand in time, the splashed metal debris can be continuously intercepted, thereby achieving continuous and efficient processing of the flange.

[0047] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
