Description

Technical Field

[0001] This invention relates to the field of forging technology, and in particular to a flange forging equipment and forming method. Background Technology

[0002] Flanges are common mechanical components widely used in piping, machinery, and structural systems to connect pipes, valves, pumps, and other equipment, ensuring a secure and sealed connection. Flanges are typically disc-shaped with a series of holes for securing two objects together with bolts or connecting the ends of two pipes. Flanges are forged during production. The blanks for forging flanges are mostly blocks or cylinders. During the forging process, they are first upsetting to form a disc shape, and then punched.

[0003] For example, the high-diameter flange forging equipment and forming method disclosed in announcement number CN119304104B can forge flanges, but it does not have the function of automatically keeping the material-limiting components away when the forging hammer column descends. As a result, when the hammer column descends to forge the material, the material deformation is restricted due to the contact between the positioning plate and the material, which reduces the effectiveness of use. Therefore, there is an urgent need to design a flange forging equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a flange forging equipment and forming method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flange forging forming device includes a worktable and further includes:

[0007] The gantry frame is fixedly installed on the top of the workbench on both vertical sides.

[0008] A hammering assembly is mounted on the horizontal side of the gantry frame and is used to hammer and upset the forging material.

[0009] The placement component is set on the worktable and is used to place the forging material. The hammering component and the placement component work together to perform comprehensive upsetting on the forging material.

[0010] The limiting component is set on the placement component and the hammering component. The limiting component is used to limit and center the forging material placed on the placement component after each hammering, so as to ensure the forging stability of the forging material.

[0011] The cleaning component is located on the horizontal side of the gantry frame. It is used to clean up the debris generated during forging, preventing the debris from affecting the hammering component's forging of the forging material.

[0012] As a further technical solution of the present invention, the hammering assembly includes: a hammering disc, which is disposed below the horizontal side of the gantry frame, and a connecting column is vertically fixedly installed at the top center of the hammering disc. A hydraulic cylinder is vertically installed at the top of the horizontal side of the gantry frame, and the output end of the hydraulic cylinder is fixedly installed at the top of the connecting column. The hydraulic cylinder is used to drive the connecting column and the hammering disc to move up and down, so as to achieve upsetting of the forging material.

[0013] As a further technical solution of the present invention, the placement component includes: a turntable, which is rotatably mounted on the top of the worktable, and the top of the turntable is provided with a receiving groove for accommodating forging materials. The bottom of the worktable is provided with a mounting groove, and a drive motor is installed inside the mounting groove. The output shaft of the drive motor is installed at the center of the bottom of the turntable, and is used to drive the turntable and the forging materials placed on it to rotate through the drive motor, so as to achieve uniform forging of the materials.

[0014] As a further technical solution of the present invention, the limiting component includes: an L-shaped plate, there are four L-shaped plates, the four L-shaped plates are uniformly fixedly installed in a ring on the surface of the turntable, and a spring rod is horizontally fixedly installed on the vertical side of each L-shaped plate. The telescopic end of the spring rod passes through the turntable and is located inside the receiving groove. It should be noted that the fixed end and the telescopic end of the spring rod are slidably connected by a spline, and the telescopic end of the spring rod slides inside the turntable.

[0015] As a further technical solution of the present invention, a vertical plate is fixedly installed on the top of the telescopic end of each spring rod, and the vertical plate is located outside the turntable. When the connecting column is lowered, the telescopic end of the spring rod can be moved by the vertical plate so that the telescopic end of the spring rod will not affect the forging of the forging material by the hammer plate.

[0016] As a further technical solution of the present invention, a pressure plate is fixedly sleeved on the surface of the connecting column, and four pressure columns are vertically fixed at the bottom of the pressure plate in a ring-shaped even distribution. Each pressure column has a ramp at its end. When the ramp contacts the top of the vertical plate, the ramp and the vertical plate slide together, so that when the pressure column descends, it can squeeze the vertical plate, so that the vertical plate can drive the telescopic end of the spring rod to move horizontally.

[0017] As a further technical solution of the present invention, the cleaning component includes: a box body, which is fixedly installed on the top of the horizontal side of the gantry frame, and a first connecting pipe is installed on the side of the box body. A first one-way valve is installed on the first connecting pipe. An air jet pipe is installed on the other side of the box body, and the air jet pipe passes through the horizontal side of the gantry frame and the pressure plate and faces the receiving groove. A second one-way valve is installed on the air jet pipe to allow external gas to enter the interior of the box body through the first connecting pipe, and the gas inside the box body to be ejected through the air jet pipe, so as to clean the debris generated during the forging of forging materials.

[0018] As a further technical solution of the present invention, a piston plate is slidably installed inside the box, and a column is vertically fixedly installed at the bottom of the piston plate. A connecting groove is opened at the bottom of the box, penetrating the horizontal side of the gantry frame, and the end of the column passes through the connecting groove and is fixedly installed on the top of the pressure plate. This is used to drive the column and piston plate to move up and down by moving the pressure plate up and down, so as to realize the pumping of air into the box.

[0019] As a further technical solution of the present invention, a baffle is vertically fixedly installed on the top of the piston plate, and the side of the baffle slides between the side of the baffle and the inner wall of the box. A through hole is opened on the side of the baffle. The baffle is used to seal between the jet pipe and the box, while the through hole is used to connect the jet pipe and the box, so as to realize the high-pressure gas inside the box is ejected to form a strong airflow to clean up the debris.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention, through the arrangement of a hammering component, a placement component, a limiting component, and a cleaning component, can center the forging material before forging and prevent the extension end of the spring rod from contacting the forging material after forging, thus ensuring the forging effect. In addition, it can automatically clean the oxide scale and debris generated on the top of the forging material during forging, and the cleaning is carried out by high-pressure gas generated by the stored force, ensuring the cleaning effect and thus improving the use efficiency of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 -Appendix Figure 7 A flange forging forming equipment includes a workbench 1, and further includes a gantry frame 2, a hammering assembly, a placement assembly, a limiting assembly, and a cleaning assembly. The two vertical sides of the gantry frame 2 are fixedly installed on the top of the workbench 1. The hammering assembly is set on the horizontal side of the gantry frame 2 and is used to hammer and upset the forging material. The placement assembly is set on the workbench 1 and is used to place the forging material. The hammering assembly and the placement assembly work together to perform comprehensive upsetting of the forging material. The limiting assembly is set on the placement assembly and the hammering assembly and is used to limit and center the forging material placed on the placement assembly after each hammering, ensuring the forging stability of the forging material. The cleaning assembly is set on the horizontal side of the gantry frame 2 and is used to clean the debris generated during forging, preventing the debris from affecting the hammering assembly's forging of the forging material.

[0033] It can center the forging material before forging and prevent the extension end of the spring rod 13 from contacting the forging material after forging, thus ensuring the forging effect. In addition, it can automatically clean the oxide scale and debris generated on the top of the forging material during forging, and the cleaning is carried out by high-pressure gas generated by the stored force, ensuring the cleaning effect.

[0034] Please see the appendix Figure 1 -Appendix Figure 6 In a preferred embodiment, the hammering assembly includes: a hammering disc 17, which is disposed below the horizontal side of the gantry 2, and a connecting column 18 is vertically fixedly installed at the top center of the hammering disc 17. A hydraulic cylinder 5 is vertically installed at the top of the horizontal side of the gantry 2, and the output end of the hydraulic cylinder 5 is fixedly installed at the top of the connecting column 18. The hydraulic cylinder 5 is used to drive the connecting column 18 and the hammering disc 17 to move up and down, so as to achieve upsetting of the forging material.

[0035] Please see the appendix Figure 1 -Appendix Figure 6 In a preferred embodiment, the placement component includes: a turntable 3, which is rotatably mounted on the top of the worktable 1, and the top of the turntable 3 has a receiving groove for receiving forging materials. The bottom of the worktable 1 has a mounting groove 9, and a drive motor 10 is installed inside the mounting groove 9. The output shaft of the drive motor 10 is installed at the center of the bottom of the turntable 3, and is used to drive the turntable 3 and the forging materials placed on it to rotate through the drive motor 10, so as to achieve uniform forging of the materials.

[0036] Please see the appendix Figure 1 -Appendix Figure 5 In a preferred embodiment, the limiting component includes: an L-shaped plate 12, there are four L-shaped plates 12, the four L-shaped plates 12 are uniformly fixedly installed in a ring on the surface of the turntable 3, and a spring rod 13 is horizontally fixedly installed on the vertical side of each L-shaped plate 12. The telescopic end of the spring rod 13 passes through the turntable 3 and is located inside the receiving groove. It should be noted that the fixed end and the telescopic end of the spring rod 13 are slidably connected by a spline, and the telescopic end of the spring rod 13 slides inside the turntable 3.

[0037] Please see the appendix Figure 1 -Appendix Figure 5 In a preferred embodiment, a vertical plate 14 is vertically fixedly installed on the top of the telescopic end of each spring rod 13, and the vertical plate 14 is located outside the turntable 3. When the connecting column 18 descends, the telescopic end of the spring rod 13 can be moved by the vertical plate 14 so that the telescopic end of the spring rod 13 will not affect the forging of the forging material by the hammering disc 17.

[0038] Please see the appendix Figure 2 -Appendix Figure 7In a preferred embodiment, a pressure plate 4 is fixedly sleeved on the surface of the connecting column 18, and four pressure columns 15 are vertically fixed at the bottom of the pressure plate 4 in a ring-shaped even distribution. Each pressure column 15 has a ramp 16 at its end. When the ramp 16 contacts the top of the vertical plate 14, the ramp 16 and the vertical plate 14 slide together, so that when the pressure column 15 descends, it can squeeze the vertical plate 14, so that the vertical plate 14 can drive the telescopic end of the spring rod 13 to move horizontally.

[0039] Please see the appendix Figure 2 -Appendix Figure 7 In a preferred embodiment, the cleaning assembly includes: a housing 6, which is fixedly installed on the top of the horizontal side of the gantry 2, and a first connecting pipe 8 is installed on the side of the housing 6. A first one-way valve is installed on the first connecting pipe 8. An air jet pipe 11 is installed on the other side of the housing 6, and the air jet pipe 11 passes through the horizontal side of the gantry 2 and the pressure plate 4 and faces the receiving groove. A second one-way valve is installed on the air jet pipe 11 to allow external gas to enter the interior of the housing 6 through the first connecting pipe 8, and the gas inside the housing 6 to be ejected through the air jet pipe 11, so as to clean the debris generated during the forging of forging materials.

[0040] Please see the appendix Figure 1 -Appendix Figure 7 In a preferred embodiment, a piston plate 21 is slidably installed inside the housing 6, and a column 20 is vertically fixedly installed at the bottom of the piston plate 21. A connecting groove 19 is opened at the bottom of the housing 6, passing through the horizontal side of the gantry frame 2, and the end of the column 20 passes through the connecting groove 19 and is fixedly installed on the top of the pressure plate 4. This is used to drive the column 20 and the piston plate 21 to move up and down by moving the pressure plate 4 up and down, so as to realize the pumping of air into the housing 6.

[0041] Please see the appendix Figure 1 -Appendix Figure 7 In a preferred embodiment, a baffle 7 is vertically fixedly installed on the top of the piston plate 21, and the side of the baffle 7 slides between the side of the baffle 7 and the inner wall of the housing 6. A through hole 22 is provided on the side of the baffle 7. The baffle 7 is used to seal the jet pipe 11 and the housing 6, while the through hole 22 is used to connect the jet pipe 11 and the housing 6, so that the high-pressure gas inside the housing 6 is ejected to form a strong airflow to clean up the debris.

[0042] When the material of the forging flange is placed inside the receiving groove, the telescopic end of the spring rod 13 will be limited by the material, so that the forging material can be centered and the effect of subsequent forging is guaranteed.

[0043] Then, the hydraulic cylinder 5 drives the connecting column 18 to move downwards. The downward movement of the connecting column 18 drives the hammering disc 17 and the pressure plate 4 to move downwards. The downward movement of the pressure plate 4 drives the column 20, the four pressure columns 15, and the ramp 16 to move downwards. The pressure columns 15 and the ramp 16 will contact the vertical plate 14 when they move downwards. When the vertical plate 14 and the ramp 16 contact each other, they will push the vertical plate 14 to move away from the turntable 3. The movement of the vertical plate 14 will drive the extension end of the spring rod 13 to move. This ensures that after the forging material is centered and when the hammering disc 17 is lowered for forging, the extension end of the spring rod 13 will not contact the forging material. This avoids limiting the forging material during the forging process and affecting the forging of the material. In addition, when the ramp 16 and the end of the vertical plate 14 no longer contact each other, the vertical plate 14 will no longer move, and the extension end of the spring rod 13 will also move to its maximum stroke. The pressure column 15 will continue to move downwards to ensure that the downward forging of the hammering disc 17 is not affected.

[0044] When the column 20 moves downward, it drives the piston plate 21 to move downward. At this time, the first one-way valve on the first connecting pipe 8 opens, while the second one-way valve on the jet pipe 11 closes, and the outside gas enters the box 6 through the first connecting pipe 8.

[0045] As the hammer plate 17 moves downwards, it will impact and forge the forging material that is centered behind it.

[0046] Next, the hydraulic cylinder 5 will drive the connecting column 18 and its connecting parts to move upward. When the pressure column 15 and the vertical plate 14 are separated, the elastic force generated by the spring rod 13 will cause its extension end to move towards the turntable 3, so as to center the impacted material again and ensure the stability of each impact. The synchronous drive motor 10 will also work to drive the turntable 3 to rotate. The rotation of the turntable 3 will drive the centered forging material, L-shaped plate 12, spring rod 13 and vertical plate 14 to rotate 90 degrees together, so as to achieve uniform impact forging of the forging material.

[0047] When the pressure plate 4 moves upward, it will drive the column 20 to move upward. The upward movement of the column 20 will drive the piston plate 21 and the baffle 7 to move upward. At this time, the first one-way valve on the first connecting pipe 8 is closed. Since the baffle 7 blocks the connection between the jet pipe 11 and the box 6, the upward movement of the piston plate 21 will compress the gas inside the box 6 to generate high pressure. Until the jet pipe 11 and the inside of the box 6 are connected through the through hole 22, the high pressure gas inside the box 6 will be ejected through the jet pipe 11 to clean the oxide scale and debris on the forging material, thus preventing the debris from affecting the forging effect when the hammer plate 17 is impacted.

[0048] In summary, the flange forging material can be forged by repeating the process. The forging material can be centered before forging, and the extension end of the spring rod 13 will no longer contact the forging material after forging, thus ensuring the forging effect. In addition, the oxide scale and debris generated on the top of the forging material can be automatically cleaned during forging. The cleaning is carried out by high-pressure gas generated by the stored force, which ensures the cleaning effect and improves the use efficiency of the equipment.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
