Description

Technical Field

[0001] This application relates to the technical field of forging devices, and particularly relates to a flange forging device. Background Art

[0002] A flange, also known as a flange plate, is a connecting part used in the industrial field. The main function of the flange plate is to connect between shafts, pipe ends, or the inlets and outlets of equipment, so as to achieve a sealed connection between pipelines, containers, or mechanical equipment. Forging is a metal processing method. By applying pressure, the metal blank undergoes plastic deformation to obtain the required shape and size. For flanges, forging can improve their internal structure and mechanical properties, such as strength and toughness.

[0003] The production methods of flange forging are divided into open die forging and die forging. The equipment used for open die forging is an open die forging hydraulic press. The forging hammer is driven by hydraulic pressure to hammer and forge the flange raw material. Each time the hammer strikes, the workpiece may displace due to vibration. At this time, it is necessary to manually adjust the position of the workpiece, which is likely to reduce the production efficiency and pose a safety hazard.

[0004] Referring to the Chinese patent document with the publication number CN219402129U and the name of a flange forging device, it includes a bottom plate, a forging hammer, and a clamping mechanism. The clamping mechanism includes a clamping frame, a double-threaded screw rod, clamping blocks, a servo motor, and a transmission belt. The clamping frame is installed on the bottom plate. The double-threaded screw rod is rotatably connected to the clamping frame. The clamping blocks for clamping the workpiece are connected to the double-threaded screw rod. The double-threaded screw rod is driven by the servo motor and the transmission belt. The forging hammer is located directly above the clamping frame. When in use, the servo motor is started to drive the clamping blocks on the double-threaded screw rod to clamp and fix the flange. Then, the forging hammer is used to forge the flange. Through the combined use of the bottom plate and the clamping mechanism, flanges of different sizes can be clamped and fixed, and at the same time, the manual adjustment of the flange position is cancelled, which can improve the safety during the working process.

[0005] Referring to the above technical solution, before forging, the clamping blocks clamp and fix the flange raw material. Then, through repeated forging by the forging hammer, during the forging process of the flange, as the flange deforms, in order to ensure the flatness of the structure at the edge of the flange, it is necessary to forge the positions of the flange that deviate from the center in sequence. However, the clamping blocks tightly clamp the flange, and it is difficult to align the positions of the flange that deviate from the center with the forging hammer, which is likely to affect the flatness of the upper surface processing at the edge of the flange and the processing quality. Summary of the Invention

[0006] In view of this, this application provides a flange forging device, which is mainly used to solve the problem of uneven processing of the upper surface edge during the forging process of the flange.

[0007] To solve the above technical problems, the present application provides a flange forging device, including a forging body, a forging hammer and a forging table. The forging hammer is driven by a hydraulic cylinder to move vertically up and down. The forging hammer is located directly above the forging table. On both sides of the forging table, screw drive members are symmetrically installed. Telescopic cylinders are arranged on the screw drive members. A V-shaped support plate I and a V-shaped support plate II are respectively installed on the two groups of telescopic cylinders. The openings of the V-shaped support plate I and the V-shaped support plate II face each other. Two groups of clamping members are arranged on the V-shaped support plate I. A clamping member and a rotating member are arranged on the V-shaped support plate II. The clamping member includes a pin shaft penetrating through the V-shaped support plate I and the V-shaped support plate II. A rotating shaft base is fixedly installed on the pin shaft. A rotating shaft for limiting the flange is arranged on the rotating shaft base. A compression spring is arranged around the pin shaft. The rotating member includes a first extension plate connected to the V-shaped support plate II. A driving roller is installed on the first extension plate.

[0008] By adopting the above technical solution, the three groups of clamping members and one group of rotating members provided can clamp and limit the flange in four directions. The driving roller on the rotating member can drive the flange to rotate. Under the action of the screw drive member, the two opposite V-shaped support plate I and V-shaped support plate II and the clamping members and rotating members installed thereon can be driven to move synchronously back and forth, so that the forging hammer deviates from the center position of the flange, completing the hammering of the edge of the flange and ensuring the flatness of the upper surface of the flange.

[0009] The clamping member and the rotating member can clamp and limit the flange. The rotating member can make the flange rotate around its own axis in place, ensuring that the forging hammer forges the edge of the upper surface of the flange in sequence, improving the flatness of the edge of the upper surface of the flange. The flange rotates under the action of the driving roller, and the rotating shaft in contact with the outer side surface of the flange rotates synchronously, which can reduce the friction between the rotating shaft and the surface of the flange and reduce the wear of the surface of the flange. The pin shaft can drive the rotating shaft to approach or move away from the inner wall of the V-shaped support plate I or the V-shaped support plate II. The compression spring can provide a certain supporting force, ensuring that the rotating shaft has a pressing force on the side surface of the flange while preventing the rotating shaft from pressing too tightly on the flange.

[0010] Optionally, L-shaped chip collection bins are arranged at the lower parts of the V-shaped support plate I and the V-shaped support plate II. A chip suction port is sleeved and installed on the L-shaped chip collection bin. The top of the chip suction port is connected to the V-shaped support plate I and the V-shaped support plate II. An air suction pump is fixedly installed on the L-shaped chip collection bin.

[0011] By adopting the above technical solution, during the telescopic process of the V-shaped support plate I or the V-shaped support plate II, the chip suction port can be driven to reciprocally telescopic in the inner cavity of the L-shaped chip collection bin. The air suction pump can suck the chips on the forging table from the chip suction port into the L-shaped chip collection bin, collecting the chips centrally, avoiding the accumulation of chips from affecting the normal operation of the equipment or the product quality. The chip suction port can quickly and effectively suck the chips into the chip collection bin, reducing the time for manual chip cleaning and improving the work efficiency.

[0012] Optionally, a filter pipe is sleeved and installed on the suction pump, and the filter pipe is sleeved on the suction port of the suction pump.

[0013] By adopting the above technical solution, the filter pipe can prevent debris from damaging the suction pump and extend the service life of the suction pump. The filter pipe is usually replaceable, which makes cleaning and maintenance simpler and faster. When the filter pipe is blocked, the filter pipe can be replaced separately without shutting down the entire suction pump for maintenance.

[0014] Optionally, a second extension plate is provided at the inner corner of the L-shaped chip collection bin.

[0015] By adopting the above technical solution, the second extension plate can prevent the debris inside the L-shaped chip collection bin from flowing out through the chip suction port.

[0016] Optionally, the lead screw drive includes a sliding block, an inner sleeve is connected to the sliding block, an outer sleeve is sleeved and installed on the inner sleeve, and the outer sleeve is fixedly connected to the first V-shaped support plate or the second V-shaped support plate respectively.

[0017] By adopting the above technical solution, the outer sleeve can slide along with the first V-shaped support plate or the second V-shaped support plate and reciprocally expand and contract on the inner sleeve. At the same time, the setting of the inner sleeve and the outer sleeve can make the first V-shaped support plate or the second V-shaped support plate more stable during sliding.

[0018] Optionally, a connecting pipe for blowing away the debris on the surface of the forging table is communicated with the outer sleeve, and a blowing one-way valve is arranged on the connecting pipe.

[0019] By adopting the above technical solution, the blowing one-way valve can blow air into the connecting pipe, blow the debris forged on the forging table to one side, and prevent the influence of the debris on the flange during forging.

[0020] Optionally, a suction one-way valve communicating with the L-shaped chip collection bin is installed inside the inner sleeve.

[0021] By adopting the above technical solution, the suction one-way valve can assist the L-shaped chip collection bin and the chip suction port in collecting debris.

[0022] Optionally, a hammer head guide shaft for returning the forging hammer to the correct position is installed on the forging machine body.

[0023] By adopting the above technical solution, during the upward lifting process after the forging hammer completes one forging, the guide shaft at a specific position can assist the forging hammer to return to the correct position, and the guide shaft can reduce the friction force with the surface of the forging hammer through its own rotation.

[0024] Optionally, the rotating member further includes a first motor installed on the first extension plate, a driving gear is connected to the output shaft of the first motor, a driven gear meshing with the driving gear is installed on the extension plate, and the central shaft of the driven gear is connected to the driving roller.

[0025] By adopting the above technical solution, the output shaft of the first motor can drive the driving gear to rotate, and then drive the driven gear meshing with the driving gear to rotate, ensuring the rotation of the driving roller.

[0026] Optionally, the driving roller is set as a roller with convex stripes on its surface, and the driving roller is made of a high-temperature-resistant material of nickel-based alloy.

[0027] By adopting the above technical solution, since the temperature of the flange itself is too high during the forging process, in order to prevent the high temperature of the flange from damaging the driving roller, using a high-temperature-resistant material can prevent the flange from being damaged by high temperature.

[0028] Optionally, the lead screw driving member further includes a second motor. A lead screw is connected to the output shaft of the second motor. The lead screw is disposed through the sliding block, and a first chute for preventing the sliding block from rotating is provided on the forging table.

[0029] By adopting the above technical solution, by rotating the second motor forward or backward, the lead screw can be driven to rotate, and the sliding block can move back and forth.

[0030] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. By driving two opposite V-shaped support plates one or V-shaped support plates two to move synchronously and reciprocally through two sets of lead screw driving members respectively, the three sets of clamping members and one set of rotating members can drive the flange to displace, making the central part of the flange deviate from directly above the forging hammer, and driving the flange to rotate under the drive of the driving roller, ensuring that the forging hammer forges the edge of the flange in sequence. Compared with the traditional technology of manually moving the flange, it not only improves the work efficiency, but also improves the safety during the work process, and at the same time can ensure the smoothness of the upper surface edge of the flange.

[0031] 2. By the combined use of multiple groups of pin shafts, compression springs and rotating shafts, during the process of the rotating shaft clamping the flange, through the shuttling of the pin shafts and the elastic support of the compression springs, the rotating shaft can not only abut and clamp the flange, but also prevent the clamping members from clamping the flange too tightly during the forging hammering, resulting in extrusion deformation of the outer surface of the flange.

[0032] 3. By providing an L-shaped chip collection bin and a chip suction port, the chips at the forging area can be centrally collected. By providing a connecting pipe and a blowing one-way valve, the chips on both sides of the forging area can be blown to the outside, preventing the chips on the forging table from affecting the forging of the flange.

Detailed implementation manners

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the Figures 1 - 7 of the embodiments of the present application.

[0036] Referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 , this embodiment provides a flange forging device, including a forging body 1, a forging table 12, a position adjustment mechanism 2, a chip collection assembly 3, a structural reinforcement member 4 and a chip blowing assembly 5. The position adjustment mechanism 2 is installed on the forging table 12 for adjusting the position of the flange, so that the center or off-center position of the circular flange corresponds to the forging hammer 11. The chip collection assembly 3 is installed on the forging table 12 for centrally collecting the chips at the forging area on the forging table 12. The structural reinforcement member 4 is installed on the forging table 12 for strengthening the stability of the position adjustment mechanism 2 during movement. The chip blowing assembly 5 is installed on the position adjustment mechanism 2 for blowing the chips on the side of the forging area to the outside. Collecting the chips at the forging area and blowing the chips on the side of the forging area can reduce the adverse effects of the chips on flange forging and ensure the flange forging quality.

[0037] A forging body 1 is provided with a forging hammer 11 and a hammer head guiding shaft 13. The forging hammer 11 is driven by a hydraulic cylinder to move vertically up and down, forging a flange placed on a forging table 12. The hammer head guiding shaft 13 is installed on the forging body 1. The forging body 1 is integrally arranged as an inverted Y-shaped plate. The hammer head guiding shaft 13 is rotatably installed at the intersection of the Y-shaped plate. The hammer head guiding shaft 13 rotates around its own axis. There are four hammer head guiding shafts 13 in total, with two arranged at the front and back respectively and symmetrically installed. When the forging hammer 11 is reset vertically upward, the hammer head guiding shaft 13 can make the forging hammer 11 return to a vertical state relative to the forging table 12.

[0038] Refer to Figure 2 and Figure 3 As shown in, the position adjusting mechanism 2 includes two groups of lead screw driving members 21, telescopic cylinders 22, a V-shaped support plate one 23, a V-shaped support plate two 24, three groups of clamping members 25 and a group of rotating members 26. The lead screw driving member 21 includes a sliding block 211. The telescopic cylinder 22 is fixedly installed on the sliding block 211. The V-shaped support plate one 23 and the V-shaped support plate two 24 are respectively installed on the piston rods of the two groups of telescopic cylinders 22. The two groups of telescopic cylinders 22 can respectively drive the V-shaped support plate one 23 and the V-shaped support plate two 24 facing each other to slide horizontally and move closer to the middle or separate from each other at the same time. Two groups of clamping members 25 are symmetrically installed at the inner corners of the V-shaped support plate one 23. One group of clamping members 25 and one group of rotating members 26 are symmetrically installed at the inner corners of the V-shaped support plate two 24. The clamping members 25 and the rotating members 26 can clamp and limit the flange, and the rotating members 26 can rotate the flange to ensure that the forging hammer 11 forges the edge of the upper surface of the flange in sequence.

[0039] Refer to Figure 3 As shown in, the clamping member 25 includes a pin shaft 251, a rotating shaft base 252, a rotating shaft 253 and a compression spring 254. A perforation is provided on the V-shaped support plate one 23 or the V-shaped support plate two 24. Each group of clamping members 25 has two pin shafts 251, which are symmetrically and penetratingly arranged on a support plate of the V-shaped support plate one 23 or the V-shaped support plate two 24. The rotating shaft base 252 located at the inner corner of the V-shaped support plate one 23 or the V-shaped support plate two 24 is fixedly installed on the pin shaft 251. The rotating shaft 253 is vertically installed on the rotating shaft base 252. The compression spring 254 is arranged around the pin shaft 251. The two ends of the compression spring 254 are respectively connected to the rotating shaft base 252 and the V-shaped support plate one 23, or the two ends of the compression spring 254 are respectively connected to the rotating shaft base 252 and the V-shaped support plate two 24.

[0040] During use, first start the telescopic cylinder 22 to drive the first V-shaped support plate 23 and the second V-shaped support plate 24 to move closer to the middle or separate from each other simultaneously, so that the rotating shafts 253 on the three clamping members 25 are all in contact with the outer side surface of the flange. As the telescopic cylinder 22 continues to extend, the pin shafts 251 displace on the perforations of the first V-shaped support plate 23 and the second V-shaped support plate 24, causing the compression springs 254 to be squeezed. The three pin shafts 251 and a set of rotating members 26 tightly abut against the flange, completing the clamping and limiting of the flange.

[0041] Referring to Figure 3 , the rotating member 26 includes a first extension plate 261, a driving roller 262, a first motor 263, a driving gear, and a driven gear. The rotating member 26 is installed on the inner wall of the second V-shaped support plate 24 and is symmetric with the clamping member 25 on the second V-shaped support plate 24. The first extension plate 261 is provided with two and is fixedly installed on the second V-shaped support plate 24 and is symmetric up and down. The driving roller 262 is vertically installed between the two first extension plates 261. The first motor 263 is installed on one of the first extension plates 261. The driving gear is installed on the output shaft of the first motor 263. A driven gear meshing with the driving gear is rotatably installed on the first extension plate 261. The driving roller 262 is connected to the central axis of the driven gear. The driving roller 262 is made of a high-temperature-resistant nickel-based alloy material to prevent the high-temperature flange from damaging the driving roller 262.

[0042] During use, when the flange is tightly abutted between the three clamping members 25 and a set of rotating members 26, by starting the first motor 263, the output shaft of the first motor 263 can drive the driving gear, the driven gear, and the driving roller 262 to rotate. The flange in contact with the driving roller 262 can rotate synchronously, so that the positions of the flange deviating from the center are sequentially aligned with the forging hammer 11, completing the forging of the edge of the upper surface of the flange.

[0043] Referring to Figure 2 , the lead screw driving member 21 includes a sliding block 211, a first sliding groove, a second motor 212, and a lead screw 213. Two sets of lead screw driving members 21 are respectively used to drive the first V-shaped support plate 23 and the second V-shaped support plate 24 to move forward and backward synchronously. Two second motors 212 are symmetrically installed on the forging table 12 from left to right. A first sliding groove corresponding to the second motor 212 is opened on the forging table 12. The lead screw 213 is installed on the output shaft of the second motor 212 and is located inside the first sliding groove. The sliding block 211 is installed on the lead screw 213. The sliding block 211 is set as a T-shaped block, and the vertical part of the T-shaped block is located inside the first sliding groove.

[0044] During use, the second motor 212 is started to drive the lead screw 213 to rotate. The sliding blocks 211 on both sides drive the first V-shaped support plate 23 and the second V-shaped support plate 24 to slide back and forth respectively, so that the clamping member 25 and the rotating member 26 drive the flange to move back and forth on the forging table 12, aligning the center position of the flange with the forging hammer 11 or aligning the off-center part with the forging hammer 11.

[0045] Refer to Figure 5 , the structural reinforcement member 4 includes an inner sleeve 41 and an outer sleeve 42. Four sets of structural reinforcement members 4 are provided to enhance the stability of the first V-shaped support plate 23 and the second V-shaped support plate 24 during expansion and contraction. The inner sleeve 41 is fixedly connected to the sliding block 211, the outer sleeve 42 is sleeved on the inner sleeve 41, and one end of the outer sleeve 42 is fixedly connected to the outside of the first V-shaped support plate 23 or the second V-shaped support plate 24.

[0046] Refer to Figure 4 , Figure 5 and Figure 6 , two sets of chip collection components 3 are provided, including an L-shaped chip collection bin 31, a chip suction port 32, an air suction pump 33, a filter pipe 34, a second extension plate 35 and an air suction check valve 36. Two second chutes 37 are vertically opened on the forging table 12, and the second chutes 37 are respectively located below the piston rods of the two telescopic cylinders 22. The vertical bin of the L-shaped chip collection bin 31 is located in the second chute 37, and the horizontal bin of the L-shaped chip collection bin 31 is located below the first V-shaped support plate 23 and the second V-shaped support plate 24. Chip suction ports 32 are installed at the lower parts of the first V-shaped support plate 23 and the second V-shaped support plate 24. The chip suction ports 32 are arranged in a rectangular tube shape and sleeved on the horizontal bin of the L-shaped chip collection bin 31, and the inner cavity of the chip suction port 32 is communicated with the horizontal bin of the L-shaped chip collection bin 31. The air suction pump 33 is installed on the L-shaped chip collection bin 31, the filter pipe 34 is sleeved on the air suction pump 33 for protecting the air suction pump 33, the second extension plate 35 is arranged at the inner corner of the L-shaped chip collection bin 31 and is horizontally arranged, and the air suction check valve 36 is installed inside the inner sleeve 41 and is communicated with the L-shaped chip collection bin 31.

[0047] During use, the air suction pump 33 is started to generate negative pressure suction inside the L-shaped chip collection bin 31, so that the chips on the forging table 12 enter the inside of the L-shaped chip collection bin 31 through the chip suction ports 32. The filter pipe 34 can prevent the high-temperature chips from damaging the air suction pump 33. The chips are collected in the L-shaped chip collection bin 31. The second extension plate 35 can prevent the chips from entering the chip suction ports 32 again. At the same time, the outer sleeve 42 slides with the first V-shaped support plate 23 or the second V-shaped support plate 24. When the outer sleeve 42 is sleeved on the inner sleeve 41, the air inside the outer sleeve 42 and the inner sleeve 41 is compressed. The air suction check valve 36 can suck the gas inside the outer sleeve 42 and the inner sleeve 41 into the L-shaped chip collection bin 31 to assist in collecting the chips inside the L-shaped chip collection bin 31.

[0048] Refer to Figure 6, the chip blowing assembly 5 is set to four groups, including a connecting pipe 51 and a blowing check valve 52. The connecting pipe 51 is connected to the outer sleeve 42, the blowing check valve 52 is installed on the connecting pipe 51, and the air outlet of the connecting pipe 51 faces the outward extension of the V-shaped support plate one 23 or the V-shaped support plate two 24.

[0049] During use, when the outer sleeve 42 is sleeved on the inner sleeve 41, by starting the blowing check valve 52 to blow air into the connecting pipe 51, the gas is blown along the outward extension directions of the V-shaped support plate one 23 and the V-shaped support plate two 24, so as to blow away the chips on the side of the forging part of the forging table 12 and reduce the influence of the chips on the flange forging.

[0050] The implementation principle of a flange forging device in an embodiment of the present application is as follows: When using this device, first start the lead screw driving member 21 to drive the sliding block 211, the V-shaped support plate one 23 and the V-shaped support plate two 24 to move synchronously back and forth, so that they are aligned with the flange on the forging table 12. Then start the three groups of clamping members 25 and one group of rotating members 26 to abut against the outer side of the flange, so that the center position of the circular flange is aligned with the forging hammer 11. The forging hammer 11 forges along the central part of the flange. Then start the lead screw driving member 21 again to align the eccentric position of the flange with the forging hammer 11. After the forging hammer 11 forges an eccentric position of the flange once, start the rotating member 26 to rotate the flange, and the forging hammer 11 forges the positions deviating from the center of the flange in turn.

[0051] During the forging process, the chip collecting assembly 3 can be started. Each time the forging hammer 11 forges the flange, chips will fall from the surface of the flange. By starting the suction pump 33, the chips falling on the forging part of the forging table 12 can be sucked into the L-shaped chip collecting bin 31 from the chip suction port 32 for centralized collection of the chips, and start the chip blowing assembly 5 to blow away the chips on the side of the forging part to reduce the influence of the chips on the flange forging.

[0052] During the reciprocating sliding of the V-shaped support plate one 23 and the V-shaped support plate two 24 driven by the telescopic cylinder 22, under the action of the structural reinforcement 4, the V-shaped support plate one 23 and the V-shaped support plate two 24 can slide more stably during the reciprocating sliding process; at the same time, when the outer sleeve 42 is sleeved on the inner sleeve 41, the gas inside the outer sleeve 42 and the inner sleeve 41 is compressed, which can assist the blowing check valve 52 to blow air into the connecting pipe 51. When the outer sleeve 42 slides and extends on the inner sleeve 41, the suction check valve 36 can input gas into the outer sleeve 42 and the inner sleeve 41, and the air inside the relative L-shaped chip collecting bin 31 is evacuated, and the generated relative suction force can assist in the collection of the chips inside the L-shaped chip collecting bin 31.

[0053] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and defined, the terms "installed", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.
