Description

Technical Field

[0001] The invention belongs to the technical field of flange forging, and in particular relates to a flange forging device. Background Art

[0002] Flange is a common mechanical part, usually used to connect two shafts or pipes, and can firmly fix them together by bolts or welding. Flange usually consists of a round flat ring plate with a certain number of holes for mounting bolts or bolts. Since the flange connection is detachable, it is easier to remove the connection parts when maintenance, replacement of equipment or cleaning of pipelines are required. This can save time and cost and improve work efficiency. Flange forging refers to a method of manufacturing flanges through a forging process. By applying pressure, the metal is plastically deformed into the desired shape and size, so that the forged flange has excellent mechanical properties, high density and strong impact resistance. Therefore, it is widely used in high-pressure, high-temperature and high-stress environments. In the process of flange forging in the prior art, it is necessary to place the high-temperature cylindrical flange forgings on a forging press, and the high-temperature forgings are formed by the forging press. However, metal forgings react with oxygen in the air at high temperatures to produce more oxide scales, which will adhere to the surface of the forgings. If they are directly forged without cleaning, the surface flatness of the flange will be reduced, the anti-corrosion performance of the flange will be affected, and the quality and performance of the flange will be affected. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a flange forging device.

[0004] The technical solution adopted to solve the above technical problems is: a flange forging device, comprising a support table, a processing table is fixedly connected to the top surface of the support table, a positioning frame is fixedly connected to the top surface of the processing table, a second reserved opening is arranged at the center of the positioning frame of the processing table, a plurality of first reserved openings are equidistantly arranged at the position of the processing table near the positioning frame, an oxide scale removal mechanism is arranged at the top of the processing table near the positioning frame, a forging transfer mechanism is arranged at the top of the processing table near the oxide scale removal mechanism, and a forging mechanism is arranged at the top of the support table near the forging transfer mechanism;

[0005] Through the above technical solution, the positioning frame is the place where the forgings are placed. After the staff places the high-temperature forgings in the positioning frame, they can start forging the flange, which is convenient for the staff to use.

[0006] The scale removal mechanism comprises an annular plate, an annular wall is fixedly connected to the top surface of the annular plate, a gear ring is fixedly connected to the top surface of the annular wall, an annular rotating frame is fixedly connected to the inner wall of the gear ring, and cleaning claws are symmetrically arranged on the inner side of the annular rotating frame;

[0007] The forging transfer mechanism includes symmetrically arranged fixed plates, which are fixedly connected to the top surface of the processing table, and a movable platform is arranged between the fixed plates.

[0009] Through the above technical scheme, when the blocks on both sides are pushed at the same time, the moving column will be driven to move in the direction of the first guide hole, so that the two cleaning claws are close to each other, and when the cleaning claws move, the spring will change from a relaxed state to a stretched state. When the thrust on the block stops, the spring will change from a stretched state back to a relaxed state, thereby driving the two cleaning claws and the block to reset. The cleaning claws are irregular arcs. When in use, the two ends of the cleaning claws will be close to the forging to be processed, and there will be a certain gap between the middle position of the cleaning claw and the forging, so that the two ends of the cleaning claws can clean and remove the oxide scale on the surface of the forging, and the arc in the middle position of the cleaning claw will limit the forging to ensure the quality of cleaning and removing the oxide scale.

[0010] Furthermore, a limiting frame is symmetrically fixedly connected to the inner wall of the annular wall, and the position of the limiting frame near the blocking block is set with an inclined surface, a push plate is provided on the side of the blocking block away from the movable column, and a push rod is fixedly connected to the side of the push plate away from the blocking block, and the push rod passes through the adjacent annular wall and is slidably connected to the annular wall, and a cylinder mounting plate is fixedly connected to the outer wall of the annular wall near the push rod, a first cylinder is installed on the cylinder mounting plate, and a piston rod of the first cylinder is fixedly connected to the adjacent push rod.

[0011] Through the above technical solution, when the first cylinder is started, it will push the push rod to move, so that the push plate pushes the card block into the card slot, and the position of the limit frame close to the card block is set as an inclined surface, so that the limit frame can always be close to the card block when it moves, and will not hinder the movement of the card block.

[0012] Furthermore, a motor mounting bracket is fixedly connected to the outer wall of the annular plate, and a first motor is mounted on the motor mounting bracket, and a driving gear is fixedly connected to the output shaft of the first motor, and the driving gear is meshed with a gear ring, and a threaded connector is fixedly connected to the outer wall of the annular plate near the first reserved opening, and a first threaded rod is threadedly connected in the threaded connector, and the bottom end of the first threaded rod passes through the first reserved opening near the first reserved opening, and a sprocket is fixedly connected to the bottom surface of the first threaded rod, and a transmission chain is arranged on the sprocket, and several of the sprockets are connected by transmission chain, and a second motor is arranged at the bottom end of any one of the sprockets, and the second motor is mounted on the top surface of the support platform, and the output shaft of the second motor is fixedly connected to the nearby sprocket, and a second cylinder is installed on the top surface of the support platform near the second reserved opening, and the piston rod of the second cylinder passes through the first reserved opening, and a lifting plate is fixedly connected to the piston rod of the second cylinder, and the lifting plate is arranged in the positioning frame.

[0013] Through the above technical scheme, when the high-temperature forging is placed in the positioning frame, the forging will be placed on the lifting plate. At this time, the second cylinder will start and push the lifting plate to move, so that the forging is placed at a high place, so that the annular plate will not touch the operating table during the use of the oxide scale removal mechanism, and when the block is completely entered into the slot, the push plate will cooperate with the limit frame to prevent the block from falling out when the annular rotating frame rotates. At this time, the first motor starts to drive the driving gear to rotate, so that the driving gear drives the ring gear to rotate, so that the ring gear drives the annular rotating frame to rotate, so that the cleaning claws on the annular rotating frame rotate together with the annular rotating frame, and the oxide scale on the surface of the forging is cleaned and removed. In addition, starting the second motor will drive the connected sprocket to rotate, so that all the sprockets rotate synchronously under the action of the transmission chain, and drive all the first threaded rods to rotate together, thereby driving the threaded connector to move along the direction of the first threaded rod, and causing the annular plate and the structure arranged thereon to move together, thereby expanding the cleaning range of the cleaning claws. When the oxide scale is removed, the block will stay at the position of the push plate. At this time, closing the first cylinder can reset the block and the cleaning claws under the action of the spring, so that the forging removal mechanism can perform all-round cleaning and removal of the oxide scale on the side of the forging, reducing the influence of the oxide scale on the flange forging quality, and improving the flange forging quality.

[0014] Furthermore, guide sleeves are symmetrically fixedly connected on both sides of the bottom surface of the movable platform, and first guide columns are slidably connected in the guide sleeves, and both ends of the first guide columns are respectively fixedly connected to the adjacent fixed plates, and a threaded sleeve is fixedly connected on the bottom surface of the movable platform, and a second threaded rod is threadedly connected in the threaded sleeve, and both ends of the second threaded rod are respectively rotatably connected to the adjacent fixed plates, and a third motor is installed on the fixed plate away from the oxide scale removal mechanism, and the output shaft of the third motor passes through the adjacent fixed plate and is fixedly connected to the second threaded rod.

[0016] Furthermore, a steering gear is fixedly connected to the bottom surface of the support column, a rack is fixedly connected to the top surface of the processing table near the steering gear, the steering gear cooperates with the rack, two limit columns are fixedly connected to the top surface of the mobile platform near the support column, a positioning ring is fixedly connected to the outer wall of the support column near the limit column, and a baffle is provided at the position of the positioning ring between the limit columns.

[0017] Through the above technical solution, when the steering gear moves to the position of the rack, it will mesh with the rack, so that the steering gear drives the support column to rotate; when the mobile platform moves to the position of the forging mechanism, the steering gear will completely pass through the rack and drive the support column to rotate a total of 90°, so that the forging can be moved to the position of the forging mechanism, and the support column will drive the positioning ring to rotate together when rotating, and the baffle on the positioning ring will move with the positioning ring. When the support column completes a 90° rotation, the baffle will be blocked by the limit column to prevent excessive rotation of the support column due to inertia, thereby improving the accuracy of forging material picking and feeding.

[0018] Furthermore, second guide holes are symmetrically arranged on the mounting block, second guide columns are slidably connected in the second guide holes, a positioning block is fixedly connected to one end of the second guide column away from the movable mounting plate, and an end of the second guide column close to the movable mounting plate is fixedly connected to the movable mounting plate, a third cylinder is installed on the top surface of the mounting block, and a piston rod of the third cylinder is fixedly connected to the movable mounting plate.

[0021] Through the above technical solution, the fourth cylinder is used to drive the connecting rod to move in the third reserved opening, so that the connecting rod drives the connected moving block to move along the direction of the third guide column. When one of the moving blocks moves, it drives the connected second connecting plate to move and rotate, so that the second connecting plate drives the first connecting plate and the rotating column to rotate, and the first connecting plate drives the second connecting plate on the other side to move and rotate, so that it drives the connected moving block to move, so that the moving blocks on both sides can move together.

[0022] Furthermore, the moving blocks are fixedly connected to moving rods, the moving rods are provided with sliding grooves, the sliding grooves are slidably connected to sliders, the sliding grooves are provided with limit stops, the sliders are rotatably connected to telescopic rods, the telescopic ends of the telescopic rods are fixedly connected to clamps, connecting columns are provided at the corners of the clamps, and the clamps on both sides are rotatably connected via the connecting columns.

When the moving rod moves, it will drive the clamping claws on both sides to rotate with the connecting column as the axis. When the clamping claws rotate, it will drive the telescopic rod to rotate on the slider, and also make the slider move along the direction of the slide groove. When the piston rod of the fourth cylinder is in the pushed-out state, the moving blocks on both sides are close to the side plates, and the slider is close to the limit block. The clamping end of the clamping claw is close to the forging to clamp the forging. When the piston rod of the fourth cylinder retracts, the moving blocks and the moving rod on both sides will approach each other, and the slider will move away from the limit block, and the clamping ends of the clamping claws will move away from each other, stopping clamping the forging, so that the clamping claws can take and discharge materials from the forging.

[0024] Furthermore, the forging mechanism includes a forging table, which is fixedly connected to the top surface of the supporting platform, a fourth reserved opening is provided at the center position of the forging table, a top material block is provided in the fourth reserved opening, a forging frame is fixedly connected to the top surface of the forging table, a forging hydraulic cylinder is installed on the top surface of the forging frame, a forging guide column is symmetrically fixedly connected to the top surface of the forging table, a first lifting platform is slidably connected to the forging guide column near the position of the forging hydraulic cylinder, a piston rod of the forging hydraulic cylinder passes through the top of the forging frame and is fixedly connected to the first lifting platform, and both sides of the bottom surface of the first lifting platform are fixedly connected to connecting A frame, a second lifting platform is fixedly connected to the bottom surface of the connecting frame, the second lifting platform is slidably connected to the forging guide column, the top surface of the forging platform and the bottom surface of the second lifting platform are fixedly connected to the forming mold, the center position of the forming mold is provided with a flange forming hole, and a hole-opening pressure block is provided in the flange forming hole located at the upper position, a hole-opening hydraulic cylinder is installed on the bottom surface of the first lifting platform, the piston rod of the hole-opening hydraulic cylinder passes through the second lifting platform and is fixedly connected to the hole-opening pressure block, and an ejection hydraulic cylinder is installed on the top surface of the support platform near the fourth reserved opening, and the piston rod of the ejection hydraulic cylinder is fixedly connected to the ejection block.

When the forging is forged into a disc shape under the action of the forming die, the drilling hydraulic cylinder will start, drive the drilling pressure block to move, so that the drilling pressure block moves from the flange forming hole at the upper position to the flange forming hole at the lower position, and the disc-shaped forging is drilled. After that, the forging hydraulic cylinder will stop, driving the first lifting platform and the second lifting platform to reset, and at the same time the ejection hydraulic cylinder will start to eject the forging block that has fallen into the fourth reserved opening, so as to realize the one-time forming of the flange forging and improve the efficiency of the flange forging.

[0026] The beneficial effects of the present invention are as follows:

[0027] (1) The present invention sets an oxide scale removal mechanism. After the staff places the forging in the positioning frame, the second cylinder will start and push the lifting plate to move, so that the forging is placed at a high place.

Then the first motor starts to drive the gear ring to rotate, so that the cleaning claws on the annular rotating frame rotate together with the annular rotating frame to clean and remove the oxide scale on the surface of the forging. In addition, starting the second motor will make all the sprockets rotate synchronously under the action of the transmission chain, thereby driving the threaded connector to move along the direction of the first threaded rod, and making the annular plate and the structure thereon move together to expand the cleaning range of the cleaning claws. When the oxide scale is removed, the block will stay at the position of the push plate. At this time, closing the first cylinder can reset the block and the cleaning claws under the action of the spring, so that the forging removal mechanism can perform all-round cleaning and removal of the oxide scale on the side of the forging, reduce the influence of the oxide scale on the flange forging quality, and improve the flange forging quality.

[0028] (2) The present invention provides a forging transfer mechanism. After the forging is cleaned and the scale is removed, the third cylinder is started to make the open jaws approach the forging, and then the fourth cylinder is started to make the clamping end of the jaws close to the forging to clamp the forging. Then the third cylinder is closed to drive the movable mounting plate to reset.

[0029] At the same time, the third motor will drive the second threaded rod to rotate, so that the mobile platform moves along the direction of the first guide column. When the steering gear moves to the position of the rack, it will mesh with the rack, so that the steering gear drives the support column to rotate. When the mobile platform moves to the position of the forging mechanism, the steering gear will completely pass through the rack and drive the support column to rotate a total of 90°. When the forging moves to the position of the forging mechanism, the third cylinder will start again to move the forging to the center position of the forming die, and then close the fourth cylinder to make the clamping ends of the clamps move away from each other, and place the forging on the forming die, thereby completing the material picking and discharging of the forging, so that after the forging is descaled, there is no need for the staff to manually move it to the forming die, which reduces the labor intensity of the staff, reduces labor costs, and improves the efficiency of flange forging.

[0063] The working principle of this embodiment is as follows. First, the staff places the forging on the lifting plate 327 in the positioning frame 203, and then the second cylinder 326 is started to push the lifting plate 327 to move, so that the forging is moved to a high place. Then the first cylinders 315 on both sides are started to drive the push rod 316 to move, so that the push plate 317 pushes the block 309 to move into the slot 305. When the block 309 completely enters the slot 305, the push plate 317 cooperates with the limit frame 313 to prevent the block 309 from being moved in the annular rotating frame 30 4 is disengaged when the cleaning claw 310 rotates, and the two ends of the cleaning claw 310 are close to the forging to be processed, and there is a certain gap between the middle position of the cleaning claw 310 and the forging to limit the forging, and when the cleaning claw 310 moves, the spring 312 changes from a relaxed state to a stretched state, and then the first motor 319 starts to drive the driving gear 320 to rotate, so that the driving gear 320 drives the ring gear 303 to rotate, so that the ring gear 303 drives the annular rotating frame 304 to rotate, so that the cleaning claw 310 on the annular rotating frame 304 is rotated. The claws 310 rotate together to clean and remove the oxide scale on the surface of the forging. At the same time, the second motor 325 will start and drive the connected sprocket 323 to rotate, so that all the sprockets 323 rotate synchronously under the action of the transmission chain 324, and drive all the first threaded rods 322 to rotate together, thereby driving the threaded connector 321 to move along the direction of the first threaded rod 322, and making the annular plate 301 and the structure arranged thereon move together to expand the cleaning range of the cleaning claw 310. When the cleaning claw 310 moves to the bottom position of the forging, the first motor 319 and the second motor 325 will stop, and the block 309 will stay at the position of the push plate 317. At this time, the first cylinder 315 will be closed, and the block 309 and the cleaning claw 310 will reset under the action of the spring 312. Then the second motor 325 will start again and rotate in the opposite direction, driving the annular plate 301 and the structure arranged thereon to reset, completing the all-round cleaning and removal of the oxide scale on the side of the forging, reducing the influence of the oxide scale on the flange forging quality, and improving the flange forging quality.

[0064] When the descaling treatment of the forging is completed, the third cylinder 417 will drive the movable mounting plate 418 to move, so that the clamping jaws 431 in the open state are close to the forging, and then the fourth cylinder 420 will start to drive the connecting rod 421 to move in the third reserved opening 419, so that the connecting rod 421 drives the connected moving block 424 to move along the direction of the third guide column 423. When one of the moving blocks 424 moves, it will drive the connected second connecting plate 434 to move and rotate, so that the second connecting plate 434 drives the first connecting plate 433 and the rotating column 432 to rotate, and the first connecting plate 433 drives the second connecting plate 433 on the other side. The connecting plate 434 moves and rotates, so that it drives the connected moving block 424 to move, so that the moving blocks 424 on both sides can move together. When the moving block 424 moves, it drives the connected moving rod 425 to move together. When the moving rod 425 moves, it drives the clamping claws 431 on both sides to rotate with the connecting column 430 as the axis. When the clamping claw 431 rotates, it drives the telescopic rod 429 to rotate on the slider 427, and also makes the slider 427 move along the direction of the slide groove 426, so that the clamping claw 431 clamps the forging. At the same time, the second cylinder 326 is closed and drives the lifting plate 327 to reset. Then the second cylinder 326 is closed and drives the lifting plate 327 to reset. The third cylinder 417 will be closed, driving the mobile mounting plate 418 to reset. At the same time, the third motor 404 will drive the second threaded rod 403 to rotate, so that the second threaded rod 403 drives the threaded sleeve 407 to move, thereby driving the mobile platform 405 to move along the direction of the first guide column 402. When the steering gear 408 moves to the position of the rack 409, it will mesh with the rack 409, so that the steering gear 408 drives the support column 410 to rotate. When the mobile platform 405 moves to the position of the forging mechanism 5, the steering gear 408 will completely pass through the rack 409 and drive the support column 410 to rotate a total of 90°, so that the forging mechanism 5 can be moved. The forging is moved to the position of the forging mechanism 5, and then the third cylinder 417 is started again to move the forging to the center position of the forming die 513. When the movement is completed, the fourth cylinder 420 is closed to make the clamping ends of the clamping jaws 431 move away from each other, and the forging is placed on the forming die 513. After that, the third cylinder 417 is closed, and the third motor 404 is started and rotated in the opposite direction, driving the mobile platform 405 to reset, completing the material collection and feeding of the forging, so that after the forging is deoxidized, it is not necessary for the staff to manually move it to the forming die 513, which reduces the labor intensity of the staff, reduces the labor cost, and improves the efficiency of flange forging;

[0065] Finally, the forging hydraulic cylinder 503 will drive the first lifting platform 505 and the second lifting platform 507 to move, so that the forming die 513 at the upper position is close to the forming die 513 at the lower position, and the forging transported to the center position of the lower forming die 513 by the forging transfer mechanism 4 is forged and formed. When the forging is forged into a disc shape under the action of the forming die 513, the hole-punching hydraulic cylinder 508 will start, driving the hole-punching pressing block 509 to move, so that the hole-punching pressing block 509 moves from the flange forming hole 514 at the upper position to the flange forming hole 514 at the lower position, and the disc-shaped forging is punched. After that, the forging hydraulic cylinder 503 will stop, driving the first lifting platform 505 and the second lifting platform 507 to reset, and at the same time, the ejection hydraulic cylinder 510 will start to eject the forging block that falls into the fourth reserved opening 511, completing the forging and forming of the flange.
