The support plate 16 is slidably connected to the inner wall of the second movable groove 29. The delivery pipe 7 is installed on the inner wall of the processing table 2 and the rear end passes through the rear side of the processing table 2. The fixed pipe 12 is installed on the inner wall of the fixed part 5; the outer sides of the plurality of air outlet holes 20 are all in contact with the inner wall of the fixed part 5, and the air outlet holes 20 are in an inclined groove structure. Air is blown downwardly through the air outlet holes 20, so that the debris on the inner wall of the lower mold 3 is blown out, thereby improving the cleaning effect. The top end of the air outlet pipe 9 is inserted into the inner ring wall of the fixing ring 15, and the second movable groove 29 is connected with the connecting groove 23. Therefore, when the air outlet pipe 9 shrinks to the inner wall of the fixed part 5, the debris on the inner wall of the fixed part 5 can also be blown out, thereby reducing the debris residue in the lower mold 3 to improve the quality of flange forging. First, place the flange blank on the top of the fixing part 5, and use its own gravity to press the air outlet pipe 9 and the lifting plate 14 downward. When the air outlet pipe 9 moves downward, it will drive the front and rear support plates 16 to slide along the inner wall of the movable groove 29, and squeeze the two springs 17 downward to be compressed on the inner wall of the movable groove 29. Then start the forging equipment body 1 to forge the flange blank. When the forging is completed, close the forging equipment body 1.

When the air outlet pipe 9 is reset upward, since a lifting plate 14 is installed on one side of the support plate 16, and the lifting plate 14 is inserted into the inner wall of the connecting groove 23, the lifting plate 4 is simultaneously driven to move upward while the spring 17 drives the support plate 16 to move upward, and separates from the bottom wall of the lower mold 3, thereby driving the forged flange upward so that the operator can take it out, thereby facilitating material unloading and improving the use effect of the forging equipment body 1. Embodiment 3: On the basis of embodiment 2, in order to increase the stability of the upward movement of the flange without affecting the forging of the flange blank, a movable groove 8 is provided on both sides of the inner part of the fixed part 5, and a push block 11 is installed on both sides of the lower part of the air outlet pipe 9, and an auxiliary groove 24 is provided on both sides of the left and right sides of the fixed part 5. The inner wall of the auxiliary groove 24 is plugged with a side arc plate 13, and the adjacent sides of the side arc plates 13 on the left and right sides are installed with a connecting block 10. Two slide grooves 21 are provided on both sides of the upper part of the fixed part 5, and a limit plate 22 is installed on the inner wall of the slide groove 21. A tension spring 19 is installed on one side of the limit plate 22, and a connecting column 18 is installed on the other side. A through groove 26 is provided on the upper part of the movable groove 8; the connecting blocks 10 on the left and right sides are It is inserted into the inner wall of the through groove 26 and fits with the inner wall of the movable groove 8. The left and right push blocks 11 are slidably connected to the inner wall of the movable groove 8, so that when the push block 11 slides upward along the inner wall of the movable groove 8, the push connection blocks 10 on both sides move backwards and drive the side arc plates 13 to fit with the inner wall of the flange after forging, thereby increasing the stability of the flange moving upward; the separated ends of the left and right connecting columns 18 pass through the auxiliary groove 24 and are installed between the side arc plates 13, and the proximal ends of the left and right tension springs 19 are installed on the inner wall of the slide groove 21, so that the elastic force of the tension spring 19 is used to conveniently drive the side arc plates 13 on both sides to shrink to the inner wall of the auxiliary groove 24, and then reset them to prevent them from affecting the forging of the flange blank. When the forged flange is driven upward, since the push blocks 11 are installed on the left and right sides of the outlet pipe 9, the push blocks 11 slide upward along the inner wall of the movable groove 8 and gradually push the connecting block 10, thereby driving the side arc plates 13 on both sides to move backward and press against the inner ring wall of the flange. At this time, the connecting columns 18 on both sides follow the movement of the side arc plates 13, driving the limit plates 22 to move backward along the inner wall of the slide groove 21, and stretching the tension spring 19, thereby increasing the stability of the flange during movement, and firmly sleeved it on the outside of the fixing part 5 so that the operator can take it out. On the contrary, when the flange blank is placed on the top of the fixing part 5, the push block 11 is separated from the connecting block 10, thereby utilizing the elastic force of the tension spring 19 to drive the side arc plates 13 on both sides to return to their original position and be stored in the inner wall of the auxiliary groove 24, thereby preventing it from affecting the forging of the flange blank. Embodiment 4: On the basis of embodiment 3, in order to clean the surface of the air outlet pipe 9 and prevent the air outlet hole 20 from being blocked, a mounting groove 25 is provided at the top of the fixing portion 5, a fixing ring 15 is installed on the inner wall of the mounting groove 25, and a brush 27 is installed on the inner ring wall of the fixing ring 15; the brush 27 is fitted to the outer side of the air outlet pipe 9, and the brush 27 is arranged in an annular structure, so that the surface of the air outlet pipe 9 is wiped by the brush 27, thereby preventing debris from blocking the air outlet hole 20 and affecting the cleaning effect. During the reciprocating up and down movement of the air outlet pipe 9, since a fixing ring 15 is installed on the inner wall of the mounting groove 25 and a brush 27 is installed on the inner ring wall of the fixing ring 15, the outer side of the air outlet pipe 9 fits with the brush 27 and its surface is cleaned, thereby reducing the residual debris on the surface of the air outlet pipe 9 and preventing the air outlet hole 20 from being blocked by debris, thereby improving the cleaning effect of the air outlet pipe 9. Embodiment 5: Based on Embodiment 4, a flange production forging process is proposed, including a flange production forging device, and the process includes the following steps: When in use, the flange blank is first placed on the top of the fixing part 5, so that the fixing part 5 and the lifting plate 14 are pushed downward by their own weight to move and reset, and then the forging equipment body 1 is started to forge the flange blank. After completion, the forging equipment body 1 is closed, and the upper mold is reset, so that the spring 17, the support plate 16, the second movable groove 29 and the air outlet pipe 9 are used to push the air outlet pipe 9 to move upward and reset, and at the same time, the air pump 6, the delivery pipe 7, the air outlet hole 20 and the fixing pipe 12 are used to cooperate, and after the air outlet pipe 9 passes through the fixing part 5, the inner wall of the lower mold 3 is blown to clean the debris on the inner wall of the lower mold 3, and no manual operation is required, thereby improving the cleaning efficiency; When the air outlet pipe 9 moves upward to reset, since a lifting plate 14 is installed on one side of the support plate 16, and the lifting plate 14 is plugged into the inner wall of the connecting groove 23, the lifting plate 14, the lifting plate 4, the spring 17 and the support plate 16 cooperate to drive the forged flange to move upward, thereby facilitating the unloading of materials. After the air outlet pipe 9 is reset, since the push blocks 11 are installed on the left and right sides of the air outlet pipe 9, the push blocks 11 are driven to push the connecting blocks 10 on both sides to move backwards, and push the side arc plates 13 to fit with the inner ring wall of the flange, and at the same time stretch the tension spring 19, so as to utilize the cooperation among the connecting column 18, the tension spring 19, the side arc plates 13 and the limit plate 22 to achieve the effect of improving the stability of the flange during the blanking process. On the contrary, when the air outlet pipe 9 shrinks to the inner wall of the fixing part 5, the push block 11 is separated from the connecting block 10, so as to utilize the tension spring 19 to stretch the side arc plates 13 to reset to the inner wall of the auxiliary groove 24; During the upward and downward movement of the air outlet pipe 9, since the inner wall of the mounting groove 25 is provided with a fixing ring 15 and the inner wall of the fixing ring 15 is provided with a brush 27, the outer side of the air outlet pipe 9 is scraped by the brush 27 to reduce the impurities remaining on the inner wall of the air outlet hole 20, thereby achieving the function of cleaning the air outlet pipe 9; According to the use requirements, the flange blank is forged, and its fixing part 5 has rich functions and is easy to use. In actual use, first place the flange blank on the top of the fixed part 5, and then use its own gravity to press the air outlet pipe 9 and the lifting plate 14 downward. When the air outlet pipe 9 moves downward, it will drive the front and rear two support plates 16 to slide along the inner wall of the movable groove 29, and squeeze the two springs 17 downward to be compressed on the inner wall of the movable groove 29, and then start the forging equipment body 1 to forge the flange blank. When the forging is completed, close the forging equipment body 1. At this time, the upper mold moves upward to reset, thereby using the elastic force of the front and rear two springs 17 to drive the two support plates 16 to reset, and push the air outlet pipe 9 upward to pass through the middle of the fixed part 5. At this time, the air pump 6 can be started to transport the gas to the inner wall of the air outlet pipe 9 through the delivery pipe 7 and the fixed pipe 12, and then blow the gas into the lower mold through the air outlet hole 20 3, so as to blow out the debris on its inner wall, so that the operator can clean the lower die 3 without the help of additional tools, thereby improving the quality of flange forging. At the same time, since the connecting groove 23 is connected with the movable groove 29, when the air outlet pipe 9 is gradually reset downward, the air outlet hole 20 is used to blow out the debris on the inner wall of the fixed part 5, thereby reducing the residue of debris on the inner wall of the lower die 3; when the air outlet pipe 9 is reset upward, since a lifting plate 14 is installed on one side of the support plate 16, and the lifting plate 14 is plugged into the inner wall of the connecting groove 23, in the process of the spring 17 driving the support plate 16 to move upward, the lifting plate 4 is synchronously driven to move upward and detach from the bottom wall of the lower die 3, thereby driving the forged flange upward so that the operator can take it out, thereby facilitating material unloading, thereby improving the use effect of the forging equipment body 1; When the forged flange is driven upward, since the push blocks 11 are installed on the left and right sides of the outlet pipe 9, the push blocks 11 slide upward along the inner wall of the movable groove 8 and gradually push the connecting block 10, thereby driving the side arc plates 13 on both sides to move backward and press against the inner ring wall of the flange. At this time, the connecting columns 18 on both sides follow the movement of the side arc plates 13, driving the limit plates 22 to move backward along the inner wall of the slide groove 21, and stretching the tension spring 19, thereby increasing the stability of the flange during movement, and firmly sleeved it on the outer side of the fixing part 5 so that the operator can take it out. On the contrary, when the flange blank is placed on the top of the fixing part 5, the push block 11 is separated from the connecting block 10, thereby using the elastic force of the tension spring 19 to drive the side arc plates 13 on both sides to return to their original position and be stored in the inner wall of the auxiliary groove 24, thereby preventing them from affecting the forging of the flange blank. During the reciprocating up and down movement of the air outlet pipe 9, since a fixing ring 15 is installed on the inner wall of the mounting groove 25 and a brush 27 is installed on the inner ring wall of the fixing ring 15, the outer side of the air outlet pipe 9 fits with the brush 27 and its surface is cleaned, thereby reducing the residual debris on the surface of the air outlet pipe 9 and preventing the air outlet hole 20 from being blocked by debris, thereby improving the cleaning effect of the air outlet pipe 9.

The top end of the air outlet pipe (9) is inserted into the inner ring wall of the fixing ring (15), and the second movable groove (29) is connected to the connecting groove (23).

10. A flange production forging process, characterized in that: The forging equipment for flange production according to any one of claims 1 to 9, wherein the process comprises the following steps: When in use, the flange blank is first placed on the top of the fixing part (5), so that the fixing part (5) and the lifting plate (14) are pushed downward by their own weight to move and reset. Then, the forging equipment body (1) is started to forge the flange blank. After completion, the forging equipment body (1) is closed and the upper mold is reset. Then, the spring (17), the support plate (16), the second movable groove (29) and the air outlet pipe (9) are used to push the air outlet pipe (9) to move upward and reset. At the same time, the air pump (6), the conveying pipe (7), the air outlet hole (20) and the fixing pipe (12) are used to blow air to the inner wall of the lower mold (3) after the air outlet pipe (9) passes through the fixing part (5) to clean the debris on the inner wall of the lower mold (3) without manual operation, thereby improving the cleaning efficiency. When the air outlet pipe (9) moves upward to reset, since a lifting plate (14) is installed on one side of the support plate (16), and the lifting plate (14) is plugged into the inner wall of the connecting groove (23), the lifting plate (14), the lifting plate (4), the spring (17) and the support plate (16) cooperate to drive the forged flange to move upward, thereby facilitating material unloading; After the air outlet pipe (9) is reset, since the push blocks (11) are installed on the left and right sides of the air outlet pipe (9), the push blocks (11) are driven to push the connecting blocks (10) on both sides upward to move backward, and push the side arc plate (13) to fit with the inner ring wall of the flange, and at the same time stretch the tension spring (19), so as to utilize the cooperation among the connecting column (18), the tension spring (19), the side arc plate (13) and the limit plate (22) to achieve the effect of improving the stability of the flange during the blanking process. On the contrary, when the air outlet pipe (9) shrinks to the inner wall of the fixing part (5), the push block (11) is separated from the connecting block (10), so as to utilize the tension spring (19) to stretch the side arc plate (13) to reset to the inner wall of the auxiliary groove (24); During the upward and downward movement of the air outlet pipe (9), since the inner wall of the mounting groove (25) is mounted with a fixing ring (15), and the inner wall of the fixing ring (15) is mounted with a brush (27), the brush (27) is used to scrape the outer side of the air outlet pipe (9) to reduce the impurities remaining on the inner wall of the air outlet hole (20), thereby achieving the function of cleaning the air outlet pipe (9); The flange blank is forged according to use requirements, and its fixing part (5) has rich functions and is easy to use.
