Description

Technical Field

[0001] The invention belongs to the technical field of radial forging equipment, in particular to a seamless steel pipe radial forging equipment and a forging method thereof. Background Art

[0002] In the field of modern industrial manufacturing, seamless steel pipes are widely used in key industries such as aerospace, energy and chemical industry, and machinery manufacturing due to their high strength, high toughness and good corrosion resistance. The radial cold forging process is a processing method that applies pressure to the metal at room temperature to cause it to produce plastic deformation. It can effectively improve the dimensional accuracy, surface finish and mechanical properties of seamless steel pipes.

[0003] During the cold forging process of seamless steel pipes using radial forging equipment, the collision and friction between the steel pipe and the mold will generate a lot of metal dust and loud noise, which not only pollutes the production environment, but also easily causes dust to enter the interior of the equipment, aggravating the wear of the mold and transmission components, and reducing the service life of the equipment. Operators will also be affected by inhaling metal dust. Noise pollution will also damage the operator's hearing. Summary of the Invention

[0014] The interior of the fixed pipe is fixedly connected with a sleeve plate, and the fan is fixedly installed inside the sleeve plate by bolts.

[0015] In the above technical solution, preferably, the filter assembly includes a mouth-shaped sleeve, which is arranged inside the fixed tube, and a metal fine filter is fixedly connected to the inside of the mouth-shaped sleeve, and the front end of the mouth-shaped sleeve passes through the front side of the fixed tube.

[0016] In the above technical solution, preferably, a cleaning mechanism is provided on the left side of the exhaust sleeve, and the cleaning mechanism includes a concave rod, the concave rod is fixedly connected to the left side of the exhaust sleeve, the surface of the concave rod is fixedly connected to a spring, the surface of the concave rod is provided with a brush plate, and the end of the spring away from the concave rod is fixedly connected to the inside of the brush plate.

[0017] In the above technical solution, preferably, the top and bottom of the brush plate are fixedly connected with a retaining ring, the inner wall of the retaining ring contacts the surface of the concave rod, and both sides of the movable plate contact the inner wall of the support sleeve.

[0018] In the above technical solution, preferably, the surfaces of the movable tube 1 and the movable tube 2 are both covered with rubber sleeves, and the front side of the rubber sleeves is fixedly connected to the back side of the fixed tube.

[0020] This solution also provides a seamless steel pipe radial forging method, comprising the following steps:

[0021] S1: First, the dual-axis motor is started. The dual-axis motor drives the bidirectional screw to rotate through the reducer. The bidirectional screw drives the two movable plates to move closer to each other. The movable plates drive the sound-absorbing cover to move through the sealing assembly. When the two sound-absorbing covers touch each other, the dual-axis motor is turned off, and then S2 is executed.

[0022] S2: The seamless steel pipe is clamped by the clamping seat, and the clamping seat drives the seamless steel pipe to rotate. At the same time, the seamless steel pipe is fed into the forging device, and the forging device is started. The forging device radially forges the steel pipe through the forging head, and then S3 is executed;

[0023] S3: Start the fan, which draws the air inside the forging device through the air duct and discharges the air into the exhaust sleeve at the same time. A directional airflow is formed through the exhaust sleeve to clean the surface of the steel pipe, effectively removing the metal dust remaining on the surface of the steel pipe, ensuring that the surface of the pipe is clean and free of impurities. The dusty air will enter the mouth-shaped sleeve, which will collect the metal dust through the metal fine filter mesh, thus forming a cycle. At the same time, the sound-absorbing cover absorbs and blocks the noise generated by forging through the microporous sound-absorbing panels.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention drives the sound-absorbing cover to seal both sides of the forging device through a dual-axis motor and a bidirectional screw, and cooperates with the microporous sound-absorbing panel to reduce noise and sound insulation, effectively improving the workshop working environment. The fan, air duct, exhaust sleeve and filter structure form a closed-loop airflow channel, which can quickly collect metal dust on the surface of the steel pipe without exchanging with the outside air, avoiding residual debris that affects the quality of forgings and equipment operation. During hot forging, this structure can effectively prevent heat from being lost with the airflow, and prevent the surface temperature of the steel pipe from suddenly dropping due to the backflow of cold air from the outside, thereby increasing the service life of the equipment, making it difficult for operators to inhale metal dust, and reducing noise pollution.

[0026] Furthermore, although the exhaust sleeve can blow off some metal dust on the surface of the steel pipe, some dust caused by forging will still adhere to the surface of the steel pipe. The structural design of the concave rod, spring and brush plate in the cleaning mechanism can ensure that the brush plate is pressed tightly on the surface of steel pipes of different specifications. During the rotation of the steel pipe, the brush plate covers and brushes the surface of the steel pipe to avoid cleaning blind spots caused by differences in pipe diameters, ensure that the surface of the steel pipe is clean and free of residue, and facilitate subsequent processing of the steel pipe.

[0027] Furthermore, although the sound-absorbing cover can block and protect against noise, when not in use, there is a hole through the steel pipe in the middle of the two sound-absorbing covers, and dust can easily enter the interior of the forging device through the hole. The design of the sealing plate, sliding rod and positioning plate and other structures in the sealing assembly can seal the sound-absorbing cover when the equipment is not in use, blocking dust, debris and other foreign matter from entering the interior of the forging device. Compared with the traditional open design, the sealing assembly can prevent foreign matter from invading and causing wear of the transmission parts of the forging device, reducing the number of equipment maintenance times; at the same time, it avoids dust accumulation affecting the performance of the sound-absorbing cover, ensuring the noise reduction effect during subsequent use.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 3 As shown, the present invention provides a seamless steel pipe radial forging device, including a forging device 1, with a clamping seat 2 fixedly connected to both sides of the forging device 1, and further comprising:

[0039] Protective members 3 are provided on both sides of the forging device 1 to protect against noise and metal dust generated by forging;

[0040] The protective member 3 includes a support sleeve 31, which is fixedly connected to both sides of the forging device 1. A transmission device 32 is provided on the front side of the forging device 1. A movable plate 33 is provided on the front and rear sides of the inner cavity of the support sleeve 31. A sealing assembly 34 is fixedly connected to the top of the movable plate 33. A sound-absorbing cover 35 is installed on the side of the sealing assembly 34 close to the forging device 1. A microporous sound-absorbing panel 36 is provided inside the sound-absorbing cover 35. An exhaust sleeve 37 located on the right side of the forging device 1 is fixedly connected to the inside of the sound-absorbing cover 35.

[0041] The air duct 38 is provided on the front of the forging device 1 and is used to connect the sound absorbing cover 35 and the exhaust sleeve 37 to form a gas circulation channel;

[0042] A filter assembly 39 is provided inside the air duct 38 , and a fan 310 is fixedly installed inside the air duct 38 .

[0043] Specifically, the forging device 1 consists of multiple hammers, a drive mechanism, and guide rails. The hammers are made of high-strength alloy, and the drive mechanism is generally a hydraulic or mechanical transmission system. It is powered by a servo motor or a hydraulic pump, which can accurately control the movement trajectory, striking frequency, and force of the hammers. During operation, the drive mechanism drives the hammers to perform high-speed reciprocating motion on the guide rails, radially forging the tube blanks with high frequency and small deformation. The clamping seat 2 consists of a movable guide rail, a clamping device, a sensor, and a clamping claw. The sensor monitors the clamping force in real time to ensure that the clamping force is moderate, avoiding the tube blank from moving due to loose clamping and preventing the tube surface from being damaged due to excessive clamping force. The fan 310 is a high-temperature resistant axial flow fan. The fan 310, the forging device 1, and the clamping seat 2 are all existing mature technical applications.

[0044] like Figures 1 to 2 As shown, the transmission device 32 includes a dual-axis motor 321, which is fixedly connected to the front of the forging device 1. Both ends of the output shaft of the dual-axis motor 321 are fixedly connected to a reducer 322 through a connecting rod, and the back of the reducer 322 is fixedly connected to the front of the support sleeve 31;

[0045] The output end of the reducer 322 passes through the interior of the support sleeve 31 and is fixedly connected to a bidirectional screw 323 . The movable plate 33 is threadedly connected to the surface of the bidirectional screw 323 . The rear end of the bidirectional screw 323 passes through the rear side of the support sleeve 31 .

[0046] Specifically, the reducer 322 is a worm gear reducer 322; through the cooperation of the dual-axis motor 321 and the reducers 322 at both ends, efficient distribution and stable transmission of power can be achieved, and the rotational motion is converted into linear motion of the moving plate 33 through the bidirectional screw 323. At the same time, the support sleeve 31 can support the bidirectional screw 323, further improving the stability and reliability of the transmission.

[0047] like Figure 4 As shown, the sealing assembly 34 includes a sealing plate 341, which is fixedly connected to the top of the movable plate 33. A sliding rod 342 is slidably connected to the interior of the sealing plate 341, and a positioning plate 343 is fixedly connected to one side of the sliding rod 342.

[0048] The side of the positioning plate 343 close to the sound absorbing cover 35 is fixedly connected to the surface of the sound absorbing cover 35, and the surface of the sliding rod 342 is provided with a tension spring 344. One end of the tension spring 344 is fixedly connected to the surface of the positioning plate 343, and the other end of the tension spring 344 is fixedly connected to the surface of the sealing plate 341. The side of the sealing plate 341 close to the sound absorbing cover 35 is in contact with the surface of the sound absorbing cover 35.

[0049] Specifically, the tension spring 344 is a stainless steel tension spring 344; when sealing is required, the dual-axis motor 321 is started, the dual-axis motor 321 drives the bidirectional screw 323 to rotate, and the bidirectional screw 323 drives the movable plate 33 and the sealing plate 341 to move. Since the two sound-absorbing covers 35 fit together, the sealing plate 341 will pull the tension spring 344. Finally, the two sealing plates 341 contact each other to seal the hole in the middle of the suction cover, blocking dust, debris and other foreign matter from entering the interior of the forging device 1, and at the same time preventing dust accumulation from affecting the performance of the sound-absorbing cover 35.

[0050] like Figures 1 to 5 As shown, the air duct 38 includes a fixed pipe 381, which is fixedly connected to the front of the forging device 1. The left side of the inner cavity of the fixed pipe 381 is slidably connected to a movable pipe 1 382, and the rear end of the movable pipe 1 382 is connected to the sound absorbing cover 35. The right side of the inner cavity of the fixed pipe 381 is slidably connected to a movable pipe 2 383, and the rear end of the movable pipe 2 383 passes through the sound absorbing cover 35 and is connected to the exhaust sleeve 37.

[0051] A sleeve plate 384 is fixedly connected to the interior of the fixed tube 381 , and the fan 310 is fixedly installed inside the sleeve plate 384 by bolts.

[0052] Specifically, the movable pipe 1 382 and the movable pipe 2 383 are connected to the sound absorbing cover 35 and the exhaust sleeve 37 respectively, and can slide flexibly in the fixed pipe 381, meeting the position change requirements of the sound absorbing cover 35 under different working conditions. The sleeve plate 384 can play a positioning and supporting role for the fan 310, so that the airflow can pass through the movable pipe 1 382 and the movable pipe 2 383 smoothly, thereby enhancing the ventilation efficiency and realizing efficient sound absorption, noise reduction and exhaust gas filtration.

[0053] like Figures 4 to 6 As shown, the filter assembly 39 includes a mouth-shaped sleeve 391, which is arranged inside the fixed tube 381. A metal fine filter 392 is fixedly connected to the inside of the mouth-shaped sleeve 391, and the front end of the mouth-shaped sleeve 391 passes through the front side of the fixed tube 381.

[0054] Specifically, the metal fine filter 392 can effectively intercept dust, particles and other impurities in the air, preventing these pollutants from entering the interior of the fan 310, and at the same time provides convenient conditions for subsequent cleaning and replacement operations. The entire filter assembly 39 can be disassembled and assembled from the front side of the fixed tube 381 without complicated disassembly, thereby improving maintenance efficiency.

[0055] like Figure 5 and Figure 8As shown, a cleaning mechanism 4 is provided on the left side of the exhaust sleeve 37, and the cleaning mechanism 4 includes a concave rod 41, which is fixedly connected to the left side of the exhaust sleeve 37, and a spring 42 is fixedly connected to the surface of the concave rod 41, and a brush plate 43 is provided on the surface of the concave rod 41, and one end of the spring 42 away from the concave rod 41 is fixedly connected to the inside of the brush plate 43.

[0056] Specifically, there are two springs 42; high-temperature resistant metal bristles are fixedly connected to the surface of the brush plate 43. When the steel pipe enters the forging device 1, one end of the steel pipe pushes the brush plate 43 to rotate around the concave rod 41, and the brush plate 43 simultaneously reels the spring 42, using the elastic force of the spring 42 to make the bristles of the brush plate 43 fit tightly against the surface of the steel pipe. This adaptive mechanism ensures that the bristles can automatically adjust the pressure according to the changes in the diameter of the steel pipe, achieving seamless contact. During the rotation of the steel pipe, the bristles peel off stubborn impurities firmly attached by forging through friction. Compared with simple airflow purging, its cleaning efficiency is significantly improved. This structure does not require complex power drive and manual intervention, relying solely on the movement of the steel pipe itself to trigger the cleaning action.

[0057] like Figure 8 As shown, the top and bottom of the brush plate 43 are fixedly connected with a retaining ring 5, the inner wall of the retaining ring 5 contacts the surface of the concave rod 41, and both sides of the movable plate 33 contact the inner wall of the support sleeve 31.

[0058] Specifically, the retaining ring 5 can prevent the brush plate 43 from moving axially during rotation, ensuring that the brush plate 43 stably rotates back and forth around the concave rod 41, and can also prevent dust and impurities from entering the gap between the concave rod 41 and the brush plate 43 to a certain extent, reducing component wear.

[0059] like Figure 5 As shown, the surfaces of the movable tube 1 382 and the movable tube 2 383 are both covered with a rubber sleeve 6 , and the front side of the rubber sleeve 6 is fixedly connected to the back side of the fixed tube 381 .

[0060] Specifically, the rubber sleeve 6 can seal the gap between the movable tube 1 382 and the fixed tube 381, effectively blocking external dust and debris from entering the gap, thereby preventing the movable tube 1 382 and the movable tube 2 383 from generating noise when moving.

[0061] like Figure 5 and Figure 6 As shown, a magnet sheet 7 is fixedly connected to the left side of the front of the mouth-shaped sleeve 391, the back of the magnet sheet 7 is attracted to the front of the fixed tube 381, and a pull plate 8 is fixedly connected to the front of the mouth-shaped sleeve 391, and the surface of the mouth-shaped sleeve 391 is in contact with the inner wall of the fixed tube 381.

[0062] Specifically, the magnet sheet 7 can fix the mouth-shaped sleeve 391, so that it remains stable during the filtration process, prevents displacement due to factors such as vibration, and ensures that the metal fine filter 392 effectively plays the role of intercepting impurities; it is convenient for the staff to quickly pull out or push the mouth-shaped sleeve 391 from the fixed tube 381 through the pull plate 8.

[0063] This solution also provides a seamless steel pipe radial forging method, comprising the following steps:

[0064] S1: First, the dual-axis motor 321 is started. The dual-axis motor 321 drives the bidirectional screw 323 to rotate through the reducer 322. The bidirectional screw 323 drives the two movable plates 33 to approach each other. The movable plates 33 drive the sound absorbing cover 35 to move through the sealing assembly 34. When the two sound absorbing covers 35 touch each other, the dual-axis motor 321 is turned off, and then S2 is executed.

[0065] S2: The seamless steel pipe is clamped by the clamping seat 2, and the clamping seat 2 drives the seamless steel pipe to rotate. At the same time, the seamless steel pipe is fed into the interior of the forging device 1, and the forging device 1 is started. The forging device 1 radially forges the steel pipe through the forging head, and then S3 is executed;

[0066] S3: Start the fan 310, which draws the air inside the forging device 1 through the air duct 38 and discharges the air into the exhaust sleeve 37. A directional airflow is formed through the exhaust sleeve 37, which can blow and clean the surface of the steel pipe, effectively removing the metal dust remaining on the surface of the steel pipe, ensuring that the surface of the pipe is clean and free of impurities. The dusty air will enter the mouth-shaped sleeve 391, so that the mouth-shaped sleeve 391 collects the metal dust through the metal fine filter 392, thus forming a cycle. At the same time, the sound-absorbing cover 35 absorbs and blocks the noise generated by forging through the microporous sound-absorbing panel 36.

[0067] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

9. The radial forging equipment for seamless steel pipes according to claim 5, characterized in that: A magnet sheet (7) is fixedly connected to the left side of the front face of the mouth-shaped sleeve (391), the back face of the magnet sheet (7) is attracted to the front face of the fixed tube (381), a pull plate (8) is fixedly connected to the front face of the mouth-shaped sleeve (391), and the surface of the mouth-shaped sleeve (391) contacts the inner wall of the fixed tube (381).

10. A method for radial forging a seamless steel pipe, using the radial forging device for a seamless steel pipe according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, the dual-axis motor (321) is started. The dual-axis motor (321) drives the bidirectional screw (323) to rotate through the reducer (322). The bidirectional screw (323) drives the two movable plates (33) to approach each other. The movable plates (33) drive the sound absorbing cover (35) to move through the sealing assembly (34). When the two sound absorbing covers (35) contact each other, the dual-axis motor (321) is turned off, and then S2 is executed. S2: The seamless steel pipe is clamped by the clamping seat (2), and the clamping seat (2) drives the seamless steel pipe to rotate, and at the same time, the seamless steel pipe is fed into the interior of the forging device (1), and the forging device (1) is started. The forging device (1) radially forges the steel pipe through the forging head, and then S3 is executed; S3: Start the fan (310), which pumps the air inside the forging device (1) through the air duct (38) and discharges the air into the exhaust sleeve (37). A directional airflow is formed through the exhaust sleeve (37), which can clean the surface of the steel pipe and effectively remove the metal dust remaining on the surface of the steel pipe, ensuring that the surface of the pipe is clean and free of impurities. The dusty air will enter the mouth-shaped sleeve (391), so that the mouth-shaped sleeve (391) collects the metal dust through the metal fine filter (392), thus forming a cycle. At the same time, the sound-absorbing cover (35) absorbs and blocks the noise generated by forging through the microporous sound-absorbing board (36).
