Description

Technical Field

[0001] This invention belongs to the field of metal plastic forming technology, specifically a rotary forging device for local plastic deformation of irregularly shaped ring forgings. Background Technology

[0002] Plastic deformation of irregular forgings refers to the irreversible permanent flow of metal billets under the constraint of a die through external force, thereby forming non-standard forgings with large cross-sectional changes and complex structures, achieving the dual goals of "forming + modification".

[0003] Due to their complex inner and outer contours, asymmetrical structures, or local features, irregularly shaped ring forgings are difficult to form with high precision through traditional integral forging or ordinary spinning processes.

[0004] In the existing technology, the processing of such irregular ring forgings usually involves spinning a high-temperature metal ring. In order to ensure that the metal can completely fill the complex cavity of the mold, a small gap is usually deliberately left on the parting surface of the mold to allow the excess metal to be squeezed out, forming a flash. If the flash that has just been cut off is stuck due to its shape or position and does not fall off or be pushed away in time, it will remain on top of the forging and can easily enter the interior of the main roller and the ring, causing wear and jamming. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a rotary forging device for localized plastic deformation of irregularly shaped ring forgings, comprising a machine body, a drive host disposed above the machine body, and a rotating frame rotatably connected above the machine body, and further comprising: A cleaning mechanism located above the rotating frame, a blowing mechanism located outside the rotating frame, and a collection mechanism installed at the bottom of the machine body; The cleaning mechanism includes a hydraulic column located below the rotating frame, a cover located below the hydraulic column, a striking assembly mounted above the cover, and a spring hook located on the outside of the cover.

[0006] Furthermore, it also includes: Side trimming wheels are symmetrically arranged outside the drive unit, and one end of the side trimming wheels is rotatably connected to the outside of the drive unit. A movable frame is disposed at one end of the machine body, and the exterior of the movable frame is slidably connected to the interior of the machine body; The core roller is positioned above the moving frame. A high-temperature metal ring is placed around the outside of the core roller, so that the main roller and the core roller clamp and shape the metal ring. The side trimming wheel is used to clamp the outside of the metal ring to maintain its stability.

[0007] Furthermore, it also includes: A drive housing, which is positioned above the rotating frame; The main roller is positioned above the machine body. An irregularly shaped ring is disposed above the core roller, and the edge of the irregularly shaped ring is in contact with the outside of the main roller.

[0008] Furthermore, the purging mechanism includes: A mounting block, wherein the mounting block is disposed outside the rotating frame; A water pipe is installed inside the mounting block, and the water pipe is connected to a water source, from which cooling water flows. An arc-shaped rod is positioned below the mounting block. One end of the arc-shaped rod is rotatably connected to the bottom of the mounting block, and the other end of the arc-shaped rod is sleeved on the outside of the water pipe. The arc-shaped rod is driven by the pipe. An aeration assembly is disposed below the water pipe.

[0009] Furthermore, the collection mechanism includes: A collection box is installed at the bottom of the machine body, and a discharge port is provided at one end of the collection box; A partition is installed inside the collection box, and the surface of the partition is provided with drainage holes.

[0010] Furthermore, the collection mechanism also includes: A water outlet pipe is installed outside the collection tank; A telescopic rod, which is installed inside the collection box; A push plate is provided at the other end of the telescopic rod, and the size of the push plate is adapted to the discharge port.

[0011] Furthermore, the tapping component includes: The sleeve is symmetrically arranged on the top of the cover. The sleeve is installed above the cover and does not contact the bottom of the rotating frame. The sleeve is a telescopic tube that can be adjusted to match the position of the cover at the bottom of the rotating frame. The counterweight is located inside the sleeve. The counterweight is similar to a dumbbell shape. The upper diameter of the counterweight is smaller than the inner diameter of the sleeve. The bottom of the counterweight is a disc-shaped metal block with multiple conical protrusions on its bottom surface to break the oxide scale that is knocked off, making it easier to clean the cover. A connecting flexible rod is provided, which is positioned above the counterweight.

[0012] Furthermore, the tapping component also includes: Mounting bracket, which is positioned above the rotating frame; The rotating plate is rotatably connected to the inside of the mounting frame, and the outside of the rotating plate is connected to the top of the connecting flexible rod. The rotating plate rotates back and forth, raising one end of the connecting flexible rod. Then the power is stopped, allowing the raised connecting flexible rod to fall naturally. The counterweight strikes the irregular ring body, breaking the oxide scale on the top of the irregular ring body for easy cleaning.

[0013] Furthermore, the gas filling assembly includes: The herringbone pipe is positioned below the water pipe, with its two ends corresponding to the surface of the movable frame, making it easy to clean the surface of the movable frame during movement. An annular tube is symmetrically arranged outside the herringbone tube and is sleeved below the herringbone tube. An air intake pipe is located outside the annular pipe. An air blower is connected to the air intake pipe to allow high-pressure airflow to enter the annular pipe, pass through a branch pipe into the conical head, and mix with the water in the water pipe.

[0014] Furthermore, the gas filling assembly also includes: A branch pipe, wherein the branch pipe is located below the intake pipe; A conical head is located at the end of the branch pipe away from the air inlet pipe. The top of the conical head has an air hole. The outlet of the conical head is small, so that the airflow comes into contact with the water before being sprayed out, increasing the impact force of the water flow. At the same time, the force of the direct wind blow is used to clean the debris on the moving frame.

[0015] The beneficial effects of this invention are as follows: 1. This invention features a cleaning mechanism where a hydraulic column moves the cover downwards, bringing the bottom of the cover close to the top of the metal ring. The cover is fan-shaped, allowing oxide scale debris to be scraped off and moved along the curved edge into the metal ring. This causes the oxide scale to fall from above the metal ring and the core roller into the middle of the metal ring. As the metal ring rotates, a striking component strikes the top of the metal ring, causing the oxide scale to break and detach from the metal ring, facilitating cleaning.

[0016] 2. This invention, by setting up a purging mechanism, allows the water sprayed during the metal ring processing to flow naturally. For forgings with complex structures or large dimensions, intense cooling can generate huge internal stresses, which can easily lead to cracking and scrapping. Therefore, low-speed water flow alone cannot clean the debris on the moving frame. At this time, the arc-shaped rod drives the water pipe and the air-filling component to sweep along the Y-shaped moving frame, so that the water flow and gas together clean the debris and blow it into the collection mechanism, keeping the moving frame clean and preventing the metal ring from being interfered with by impurities during the shaping process.

[0017] 3. This invention incorporates a striking component. The rotating plate drives the connecting flexible rod to lift the counterweight upwards, and then releases it, allowing the counterweight to fall naturally. The gravitational potential energy of the falling counterweight is converted into impact kinetic energy. This instantaneous impact force is sufficient to cause cracks in the brittle oxide scale and peel off in pieces. As a constant and finite force, the counterweight is just enough to break the oxide scale without causing plastic deformation or damage to the ring. Furthermore, the sharp protrusions at the bottom of the counterweight can break the oxide scale into small pieces, making it easier to clean.

[0018] 4. This invention, by setting up an air-filling component, allows the airflow entering through the annular pipe to pass through the branch pipe into the conical head, where it mixes with the water flow and is sprayed out together. Due to the high temperature of the metal ring, the water flow slowly flows out and sprays onto the surface of the metal ring, which can prevent the metal from cracking during the molding process. Therefore, the water flow intensity cannot achieve the purpose of cleaning the oxide scale debris above the moving frame, but increases the airflow interference. This can blow away the debris without affecting the molding of the metal ring, preventing the debris from accumulating on the moving frame for a long time and being rolled into the bottom of the metal ring, thus affecting the molding of the metal ring surface.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a rotary forging device for local plastic deformation of irregularly shaped ring forgings is described below.

[0023] The system includes a main body 1, a drive unit 2 mounted on top of the main body 1, and a rotating frame 3 rotatably connected to the main body 1. It also includes: The cleaning mechanism 4 is located above the rotating frame 3, the blowing mechanism 5 is located outside the rotating frame 3, and the collecting mechanism 6 is installed at the bottom of the body 1; Also includes: Side trimming wheels 7 are symmetrically arranged on the outside of the drive host 2, and one end of the side trimming wheels 7 is rotatably connected to the outside of the drive host 2. The movable frame 11 is located at one end of the body 1, and the exterior of the movable frame 11 is slidably connected to the interior of the body 1. The core roller 9 is positioned above the moving frame 11. A high-temperature metal ring is placed around the outside of the core roller 9, so that the main roller 10 and the core roller 9 clamp and shape the metal ring. The side trimming wheel 7 is used to clamp the outside of the metal ring to maintain its stability.

[0024] Also includes: Drive box 12, drive box 12 is located above the rotating frame 3; Main roller 10 is positioned above machine body 1; The irregular ring 8 is positioned above the core roller 9, and its edge is in contact with the outside of the main roller 10. The irregular ring 8 is formed by heating and shaping a metal ring.

[0025] During operation, the rotating frame 3 is opened, and the high-temperature metal ring is placed on the core roller 9. The rotating frame 3 is then closed, and the moving frame 11 moves the core roller 9 closer to the machine body 1. Subsequently, the drive box 12 drives the core roller 9 to rotate, so that the main roller 10 and the core roller 9 shape the metal ring. The side trimming wheel 7 assists in shaping the metal ring from both sides, eventually forming an irregularly shaped ring 8. While the metal ring is rotating, the cleaning mechanism 4 breaks and cleans the oxide scale on the metal ring. The flash cut off during the shaping process falls into the collection mechanism 6. The blowing mechanism 5 blows the oxide scale and other debris on the moving frame 11 into the collection mechanism 6 for cooling and collection.

[0026] The cleaning mechanism 4 includes a hydraulic column 401 disposed below the rotating frame 3, a cover 402 disposed below the hydraulic column 401, a striking assembly 404 mounted above the cover 402, and an elastic hook 403 disposed on the outside of the cover 402. The elastic hook 403 can contact the top of the core roller 9, so that the top of the core roller 9 contacts the elastic hook 403 to clean the debris above the core roller 9.

[0027] During the shaping of the metal ring, the hydraulic column 401 drives the cover 402 to move downward, so that the bottom of the cover 402 is close to the top of the metal ring. The cover 402 is fan-shaped, which allows the oxide scale debris to be scraped off and moved along the arc edge to the inside of the metal ring, so that the oxide scale falls from above the metal ring and the core roller 9 into the middle of the metal ring. When the metal ring rotates, the striking component 404 strikes the top of the metal ring, so that the oxide scale is broken by external force and detached from the metal ring, making it easy to clean.

[0028] The purging mechanism 5 includes: The mounting block 501 is disposed on the outside of the rotating frame 3; Water pipe 502 is installed inside the mounting block 501. Water pipe 502 is connected to a water source and cooling water flows in from water pipe 502. Water pipe 502 is a deformable hose. An arc-shaped rod 503 is positioned below the mounting block 501. One end of the arc-shaped rod 503 is rotatably connected to the bottom of the mounting block 501, and the other end of the arc-shaped rod 503 is sleeved on the outside of the water pipe 502. The arc-shaped rod 503 is driven. The gas filling component 504 is located below the water pipe 502.

[0029] When cleaning the metal oxide scale, some debris will fall onto the moving frame 11. Under normal circumstances, the water sprayed during the metal ring processing flows naturally. For forgings with complex structures or huge sizes, the intense cooling will generate huge internal stress, which can easily lead to cracking and scrapping. Therefore, the debris on the moving frame 11 cannot be cleaned by the low-speed water flow alone. At this time, the arc rod 503 drives the water pipe 502 and the air filling component 504 to sweep along the Y-shaped moving frame 11, so that the water flow and gas can clean the debris together and blow it into the collection mechanism 6, keeping the moving frame 11 clean and avoiding the metal ring from being interfered with by impurities during the molding process.

[0030] Collection agency 6 includes: Collection box 601 is installed at the bottom of the machine body 1, and a discharge port 606 is provided at one end of the collection box 601; A partition 602 is installed inside the collection box 601, and the surface of the partition 602 is provided with drainage holes.

[0031] Collection agency 6 also includes: Water outlet pipe 603 is located outside the collection box 601; Telescopic rod 604 is installed inside collection box 601; Push plate 605 is set at the other end of telescopic rod 604, and the size of push plate 605 is adapted to the discharge port 606.

[0032] When forming the irregular ring 8 by metal ring molding, an external water source is required to spray water on the metal. The collection box 601 can recover the cooling water and concentrate it in the collection box 601. After cleaning the debris and flash into the collection box 601, the cooling water cools the oxide scale and flash. Then, the push plate 605 is driven by the telescopic rod 604 to clean the debris, so that the debris is discharged from the discharge port 606. This avoids the hot metal debris falling into the collection tank and needing more time to cool down, which would prevent it from being cleaned up quickly.

[0033] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the tapping component 404 includes: Sleeve 4041 is symmetrically arranged on the top of cover 402. Sleeve 4041 is installed above cover 402 and does not contact the bottom of rotating frame 3. Sleeve 4041 is a telescopic tube that can be adjusted to the position of cover 402 at the bottom of rotating frame 3. The counterweight 4043 is located inside the sleeve 4041. The counterweight 4043 is similar to a dumbbell shape. The upper diameter of the counterweight 4043 is smaller than the inner diameter of the sleeve 4041. The bottom of the counterweight 4043 is a disc-shaped metal block with multiple conical protrusions on its bottom surface to break the oxide scale that is knocked off, making it easier for the cover 402 to clean. Connecting flexible rod 4042 is positioned above counterweight 4043.

[0034] The tapping component 404 also includes: Mounting bracket 4044 is positioned above the rotating bracket 3; The rotating plate 4045 is internally rotatably connected to the mounting bracket 4044, and externally connected to the top of the connecting flexible rod 4042. The rotating plate 4045 rotates back and forth, raising one end of the connecting flexible rod 4042. Then the power is stopped, allowing the raised connecting flexible rod 4042 to fall naturally. The counterweight 4043 strikes the irregular ring 8, breaking the oxide scale on the top of the irregular ring 8 for easy cleaning.

[0035] During the metal forming process, the rotating plate 4045 drives the connecting flexible rod 4042 to lift the counterweight 4043 upwards, and then releases it, allowing the counterweight 4043 to fall naturally. The gravitational potential energy of the counterweight 4043 falling naturally is converted into impact kinetic energy. This instantaneous impact force is enough to cause the brittle oxide scale to crack and peel off in pieces. As a constant and finite force, the counterweight 4043 can just break the oxide scale, but it is not enough to cause plastic deformation or damage to the ring. In addition, the sharp protrusions at the bottom of the counterweight 4043 can break the oxide scale into small pieces, making the oxide scale easier to clean.

[0036] The gas filling assembly 504 includes: The herringbone pipe 5041 is located below the water pipe 502. The two ends of the herringbone pipe 5041 correspond to the surface of the movable frame 11, which makes it easy to clean the surface of the movable frame 11 during the movement. An annular tube 5042 is symmetrically arranged outside the herringbone tube 5041, and the annular tube 5042 is sleeved below the herringbone tube 5041. The air inlet pipe 5043 is located outside the annular pipe 5042. The air inlet pipe 5043 is connected to an air blower, which allows the high-pressure airflow to enter the annular pipe 5042, and then enter the conical head 5045 through the branch pipe 5044, where it mixes with the water in the water pipe 502.

[0037] The gas filling assembly 504 also includes: Branch pipe 5044 is located below intake pipe 5043; The conical head 5045 is located at the end of the branch pipe 5044 away from the air inlet pipe 5043. The top of the conical head 5045 has an air hole 5046. The outlet of the conical head 5045 is small, so that the airflow comes into contact with the water before being sprayed out, increasing the impact force of the water flow. At the same time, the force of the direct wind blow is used to clean the debris on the moving frame 11.

[0038] When the oxide scale falls off, it will stay on the moving frame 11. At this time, the arc rod 503 drives the water pipe 502 to move back and forth, so that water enters the herringbone pipe 5041 and sprays out. At the same time, the airflow entering the annular pipe 5042 enters the conical head 5045 through the branch pipe 5044, mixes with the water flow, and sprays out together. Due to the high temperature of the metal ring, the water flow slowly flows out and sprays onto the surface of the metal ring, which can prevent the metal from cracking during the shaping process. Therefore, the strength of the water flow cannot achieve the purpose of cleaning the oxide scale debris above the moving frame 11, thereby increasing the airflow interference. It can blow away the debris without affecting the shaping of the metal ring, and prevent the debris from accumulating on the moving frame 11 for a long time and being rolled into the bottom of the metal ring, which would affect the shaping of the surface of the metal ring.

[0039] The specific workflow is as follows: During operation, the rotating frame 3 is opened, and the high-temperature metal ring is placed on the core roller 9. The rotating frame 3 is closed, and the moving frame 11 moves the core roller 9 closer to the machine body 1. Then, the drive box 12 drives the core roller 9 to rotate, so that the main roller 10 and the core roller 9 shape the metal ring. The side trimming wheel 7 assists in shaping the metal ring from both sides, and finally becomes an irregularly shaped ring body 8. When the metal ring rotates, the cleaning mechanism 4 breaks and cleans the oxide scale on the metal ring. The flash cut off during the shaping process falls into the collection mechanism 6. The blowing mechanism 5 blows the oxide scale and other debris on the moving frame 11 into the collection mechanism 6 for cooling and collection. During the shaping of the metal ring, the hydraulic column 401 drives the cover 402 to move downward, so that the bottom of the cover 402 is close to the top of the metal ring. The cover 402 is fan-shaped, which allows the oxide scale debris to be scraped off and moved along the arc edge to the inside of the metal ring, so that the oxide scale falls from above the metal ring and the core roller 9 into the middle of the metal ring. When the metal ring rotates, the striking component 404 strikes the top of the metal ring, so that the oxide scale is broken by external force and detached from the metal ring, making it easy to clean. When cleaning the metal oxide scale, some debris will fall onto the moving frame 11. At this time, the arc rod 503 drives the water pipe 502 and the air filling component 504 to sweep along the Y-shaped moving frame 11, so that the water and gas can clean the debris together and blow it into the collection mechanism 6, keeping the moving frame 11 clean and preventing the metal ring from being interfered with by impurities during the molding process. When forming the irregular ring 8 by metal ring molding, an external water source is required to spray water on the metal. The collection box 601 can recover the cooling water and concentrate it in the collection box 601. After cleaning the debris and flash into the collection box 601, the cooling water cools the oxide scale and flash. Then, the push plate 605 is driven by the telescopic rod 604 to clean the debris, so that the debris is discharged from the discharge port 606. This avoids the hot metal debris falling into the collection tank and needing more time to cool down, which would prevent it from being cleaned up quickly.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
