Description

Technical Field

[0001] The present invention relates to the technical field of flange processing, in particular to a forging device and process for an anchor bolt base flange. Background Art

[0002] Flange, also known as flange or flange, is a part that connects shafts to each other and is used to connect pipe ends. It is also used on the inlet and outlet of equipment to connect two devices, such as reducer flanges. Flanges are used in pairs.

[0003] Forging is a processing method that uses a forging machine to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than those of castings of the same material. For important parts in related machinery with high loads and severe working conditions, forgings are mostly used, except for simpler shapes that can be made of rolled plates, profiles or welded parts.

[0004] During the production process, flanges need to be forged and rolled. However, for existing devices for forging anchor bolt foundation flanges, since the forging head is driven by a cylinder to move straight up and down, multiple workers are still needed to adjust the position of the flange during the flange forging process, which not only reduces the production efficiency of the flange, but also may cause dangerous accidents such as burns to workers due to the splashing of high-temperature debris on the flange surface during forging. Summary of the Invention

Since the forging head is driven straight up and down by a cylinder, multiple workers still need to intervene in the flange forging process to adjust the position of the flange, which not only reduces the production efficiency of the flange, but also causes dangerous accidents such as burns to the workers due to the splashing of high-temperature debris.

[0017] In a preferred embodiment, the lifting cylinder is movably connected to the upper end of the forging table, the fixing seat is welded inside the forging table, and the lifting cylinder is slidably connected to the outer wall of the fixing seat.

[0018] A forging process for an anchor bolt foundation flange, the specific contents are as follows:

[0019] S1: Place the blank to be forged on the fixed seat, then start the second motor. One of the half gears starts to rotate, driving the other half gear to rotate. Then, the first connecting rod drives the two second rotating shafts to move closer to each other, thereby driving the two fourth connecting rods to extend and move closer together. The first clamping plate completes the clamping of the side of the blank.

[0020] S2: After the clamping is completed, the first cylinder is started to drive the limit box to move up and down, thereby driving the forging head to forge the blank body. During the forging process, the two fourth cylinders are started to extend, so that the two second clamping plates clamp the blank body. At this time, the third motor is started to drive the fourth cylinder to rotate through the fourth gear and the fifth gear, thereby driving the blank body to reciprocate through the second clamping plates, so that the forging of the blank body is more uniform, thereby completing the initial forging of the blank body.

[0021] S3, after the initial forging is completed, the fourth cylinder is reset, and the fifth cylinder is started to drive the lifting cylinder to rise out of the forging table. At the same time, the second motor drives the connecting rod four to reset and release the blank body. The blank body is placed in the lifting cylinder, and then the first motor is started to drive the third gear to rotate, thereby driving the second gear and the first gear to rotate. The first gear drives the extension column to rotate to the meshing position of the first gear and the second gear. Under the limitation of the 8-shaped opening, the connecting piece and the bottom plate protrusion, the extension column slides from the second limiting opening at the lower end of the first gear into the second limiting opening under the second gear. Through the mutual cooperation between the extension plate of the special-shaped part and the second limiting openings on the first gear and the second gear, and the cooperation between the lower end of the special-shaped part and the first limiting opening, the special-shaped part moves in an 8-shaped trajectory, driving the forging head to fully hammer and forge the blank body until the upper end surface of the blank body is flush with the upper end surface of the lifting cylinder. Then the fifth cylinder is started to move downward. Under the limiting action of the fixed seat, the forged blank body is separated from the lifting cylinder, completing the forging work on the blank body.

[0022] The present invention greatly reduces manual intervention and direct operations of workers during the forging process through the mutual cooperation of the hammer forging unit and the die unit, and the setting of multiple automated mechanical structures, thereby significantly improving the production efficiency of anchor bolt foundation flanges, effectively reducing the safety risks caused by high-temperature debris splashing, and providing workers with a safer working environment. Traditional forging devices require workers to intervene to adjust the flange position, which increases the contact time between workers and the high-temperature forging area. However, in the entire forging process of the present invention, workers only need to place the flange blank body to be forged on the fixed seat by means of a forklift, and subsequent clamping, rotation and forging operations are done by the forging machine. All operations are performed automatically, eliminating the need for workers to approach the hot forging area. This fundamentally reduces the risk of burns and other safety hazards, effectively ensuring worker safety. In practice, after loading, the second motor is activated, and the two half gears mesh, driving connecting rod four to quickly clamp the flange blank to be forged. This process is rapid and stable, requiring no manual positioning. During the forging phase, the first cylinder drives the limit box and forging head to hammer the blank. Simultaneously, the fourth cylinder and the third motor work together to drive the second clamping plate to clamp the lower end of the blank and rotate it back and forth at a small angle, ensuring a seamless and orderly initial forging process. After the initial forging is completed, the fifth cylinder raises the lifting cylinder off the forging table. The second motor resets connecting rod four. The first motor then drives the first and second gears, driving the forging head to forge the entire blank within the lifting cylinder in a figure-eight trajectory. The tight coordination of these components significantly shortens the forging cycle for a single flange and significantly improves production efficiency compared to traditional systems.

[0023] The present invention makes the forging process more uniform and significantly improves the forging quality of the anchor bolt base flange through the unique forging head motion trajectory and workpiece rotation design. During the initial forging, the second clamping plate drives the blank body to rotate back and forth at a small angle to ensure that the blank body is uniformly stressed in the vertical direction. During the comprehensive forging stage, the forging head, driven by the special-shaped part, moves according to an 8-shaped trajectory, and can comprehensively and evenly hammer all parts of the blank body. This all-round, multi-angle forging method makes the internal structure of the metal denser and the organization more uniform, effectively eliminating problems such as stress concentration that may occur during the forging process, thereby improving the mechanical properties and product quality of the anchor bolt base flange.

[0035] 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.

[0036] See also Figures 1-9 , the present invention provides a technical solution: a forging device for an anchor bolt foundation flange, comprising a blank body 1 and a forging table 2, and further comprising;

[0037] A hammer forging unit for hammering the blank body 1, the hammer forging unit including a moving component for limiting the blank body 1 and a forging component for forging the blank body 1, the forging component including a forging head 3, a special-shaped part 4 for driving the forging head 3 to move, a first limiting opening 5 for limiting the movement of the lower end of the special-shaped part 4, and a second limiting opening 6 for limiting the upper end of the special-shaped part 4, the second limiting opening 6 being respectively provided on a first gear 7 and a second gear 8, the first gear 7 and the second gear 8 being driven by a driving mechanism, the first limiting opening 5 being provided on the wall of a limiting box 9, and the upper end of the forging head 3 being fixedly connected to the special-shaped part 4 via a connecting member 10;

[0038] The driving mechanism drives the first gear 7 and the second gear 8 to rotate. The extension column 42 of the special-shaped part 4 moves along a specific figure-8 trajectory under the common limitation of the second limiting opening 6 at the lower end of the first gear 7 and the second gear 8 and the figure-8 opening, and then drives the forging head 3 through the connecting member 10 to perform all-round forging on the blank body 1 placed on the die unit. The forging head 3 can move along the figure-8 trajectory to achieve uniform forging of multiple parts of the flange blank body 1, avoiding the uneven forging problem caused by the traditional straight-up and straight-down forging method, and effectively improving the forging quality of the flange.

[0039] and a die unit for shaping the blank body 1 during forging, wherein the die unit is arranged in the forging table 2 .

[0040] The first gear 7 and the second gear 8 are both rotatably connected to the inner walls of the first gear 7 and the second gear 8, and the lower ends of the two support columns 11 are fixedly connected to a base plate 12 with a protrusion at one end, and the upper ends of the two support columns 11 are fixedly connected to the inner wall of the upper end of the limit box 9, and an 8-shaped opening is formed between the side walls of the two base plates 12 and the side walls of the first limit opening 5. The special-shaped part 4 includes a sleeve 40, an extension plate 41 integrally formed with the two side walls of the sleeve 40, and an extension column 42 fixedly arranged on the upper end of the sleeve 40, and a first rotating shaft 43 is rotatably connected to the inner wall of the extension plate 41, and the lower end of the first rotating shaft 43 is fixedly connected to the connecting plate 44, and the length of the first rotating shaft 43 matches the thickness of the base plate 12, and the protrusion at one end of the base plate 12 is movably embedded between the extension plate 41 and the connecting plate 44, and the lower end side wall of the extension plate 41 is fixedly connected to the side wall of the connecting plate 44.

[0041] When the first gear 7 and the second gear 8 rotate, the extension column 42 moves along the 8-shaped opening and the second limit opening 6, and the extension plate 41 swings around the first rotating shaft 43, driving the connecting plate 44 and the forging head 3 connected thereto to cooperate to realize the 8-shaped forging trajectory. This structure ensures that the special-shaped part 4 can stably move according to the preset 8-shaped trajectory, providing a stable and precise movement path for the forging head 3. At the same time, through the connection method between the extension plate 41 and the connecting plate 44, the special-shaped part 4 is more flexible and adaptable during the movement.

[0042] The connecting member 10 includes a first support block 100 that is slidably connected to the lower end wall of the limit box 9, a groove 101 opened at the upper end of the first support block 100, and a second support block 102 fixed in the groove 101, the upper end of the second support block 102 is lower than the upper end of the first support block 100, the lower end of the connecting plate 44 is fixedly connected to the upper end of the second support block 102, the lower end of the second support block 102 is fixedly connected to the forging head 3, the upper end of the limit box 9 is fixedly connected to the output shaft of the first cylinder 13, the upper end of the first cylinder 13 is fixed on the upper end wall of the forging table 2, and one end of the limit box 9 is slidably connected to the wall of the forging table 2.

[0043] The first cylinder 13 drives the limit box 9 to move up and down, so that the forging head 3 moves up and down to realize the hammer forging of the blank body 1. At the same time, the second support block 102 slides in the groove 101 of the first support block 100 to ensure the stability of the forging head 3 when following the movement of the special-shaped part 4. This connection method not only ensures that the forging head 3 can make an 8-shaped movement with the special-shaped part 4, but also can be hammered up and down under the drive of the first cylinder 13, realizing a combination of multiple movement modes and improving the flexibility and comprehensiveness of the forging process.

[0044] The driving mechanism includes a first motor 14 installed at the upper end of the limit box 9 and a third gear 15 fixedly connected to the output shaft of the first motor 14. The third gear 15 is rotatably arranged in the limit box 9 and is meshed with the first gear 7. The number of the second limit openings 6 is 6, of which three second limit openings 6 are equidistantly opened at the lower end of the first gear 7, and the other three second limit openings 6 are equidistantly opened at the lower end of the second gear 8.

[0045] After the first motor 14 is started, it drives the third gear 15 to rotate, and the third gear 15 drives the first gear 7 to rotate, thereby driving the second gear 8 associated therewith to rotate synchronously, providing power for the movement of the special-shaped part 4.

[0046] The movable component includes a clamping mechanism, which includes two symmetrically distributed half gears 16, a connecting rod 17 fixedly connected to the inner wall of the half gear 16, a second rotating shaft 18 rotatably connected to the inner wall of the connecting rod 17, a connecting rod 2 19 rotatably connected to the outer wall of the second rotating shaft 18, a connecting rod 4 20 fixedly connected to the connecting rod 2 19 and a first clamping plate 21 fixedly connected to one end of the connecting rod 4 20, the two half gears 16 are meshed and connected, one end of the connecting rod 2 19 is rotatably connected to the connecting rod 3 22 at the upper and lower ends, and the other end of the connecting rod 3 22 is rotatably connected to a base 23 slidably connected to the upper end of the forging table 2, one of the inner walls of the connecting rod 1 17 is fixedly connected to the output shaft of the second motor 24 installed on the base 23, the lower end of the second rotating shaft 18 is slidably connected to the base 23, and one end of the base 23 is fixedly connected to the output shafts of two second cylinders 25 installed on the wall of one end of the forging table 2.

[0047] Start the second motor 24 to drive one of the half gears 16 to rotate, and through the meshing action, the other half gear 16 rotates in the opposite direction, so that the two connecting rods 20 move closer to or away from each other, thereby clamping and releasing the blank body 1; the second cylinder 25 can push the base 23 to slide and adjust the position of the clamping mechanism. The automated clamping process reduces manual operation and improves production efficiency. At the same time, through the cooperation of the motor and the cylinder, the clamping force and position can be accurately controlled to ensure the stability of the blank body 1 during the forging process.

[0048] The movable member also includes two symmetrically distributed rotating mechanisms, which include a third cylinder 26 mounted on the side wall of the forging table 2, a fixed block 27 fixedly connected to the output shaft at the upper end of the third cylinder 26, a fourth cylinder 28 rotatably mounted on the inner wall of the fixed block 27, a fourth gear 29 mounted on the outer wall of the fourth cylinder 28, a second splint 30 fixedly connected to the output shaft of the fourth cylinder 28, a fifth gear 31 meshing with the fourth gear 29, and a third motor 32 whose output shaft is fixedly connected to the fifth gear 31, and the third motor 32 is mounted on the fixed block 27.

[0049] The fourth cylinder 28 drives the second clamping plate 30 to clamp the blank body 1, and the third motor 32 drives the fourth cylinder 28 and the second clamping plate 30 to rotate through the engagement of the fourth gear 29 and the fifth gear 31, so that the blank body 1 can rotate at a small angle during the forging process. During the forging process, the blank body 1 can rotate at a small angle, ensuring that multiple parts of the blank body 1 are evenly stressed and improving the forging quality. At the same time, through the combined control of the third cylinder 26, the fourth cylinder 28 and the third motor 32, the operation is more flexible and can adapt to the forging needs of flange blank bodies 1 of different sizes and shapes.

[0050] A laser rangefinder 33 is installed at the upper end of the two fixed blocks 27. The laser rangefinder 33 electrically controls the rotation angles of the first motor 14, the second motor 24, and the third motor 32, as well as the extension and retraction distances of the first cylinder 13, the second cylinder 25, the third cylinder 26, and the fourth cylinder 28 through a controller 34 installed on the wall of one end of the fixed block 27.

[0051] The laser rangefinder 33 measures the position and size information of the blank body 1 in real time and transmits the data to the controller 34. The controller 34 controls the actions of the first motor 14, the second motor 24, the third motor 32 and the first cylinder 13, the second cylinder 25, the third cylinder 26 and the fourth cylinder 28 according to preset programs and parameters. When the length of the blank body 1 changes during forging, the laser rangefinder 33 detects that the distance is getting closer and controls the distance between the four connecting rods 20 to become larger. At the same time, the second cylinder 25 drives the base 23 to move toward the blank body 1, so that the position of the first clamping plate 21 on the four connecting rods 20 is always in an appropriate position to clamp the blank body 1. At the same time, the fourth cylinder 28 is controlled to shorten, driving the two second clamping plates 30 to clamp blank bodies 1 of different lengths, thereby realizing automated and intelligent control of the equipment, improving the accuracy and consistency of the forging process, reducing the influence of human factors, and being able to quickly adjust the operating parameters of the equipment according to different forging requirements, thereby improving the versatility and adaptability of the equipment.

[0052] The mold unit includes a fifth cylinder 35, a lifting block 36, a lifting cylinder 37 and a fixed seat 38. Two symmetrically distributed fifth cylinders 35 are fixedly installed at the bottom end of the forging table 2. The output shaft at the upper end of the fifth cylinder 35 is fixedly connected to the lifting block 36, and the upper end of the lifting block 36 is fixedly connected to the lifting cylinder 37.

[0053] The fifth cylinder 35 is started, driving the lifting block 36 and the lifting cylinder 37 to rise or fall, thereby adjusting the position of the blank body 1 placed on the fixed seat 38, providing support and shaping for the blank body 1 during the forging process. The liftable lifting cylinder 37 can adjust the height of the blank body 1 according to the needs of the forging process, facilitating the comprehensive forging of the forging head 3. At the same time, the fixed seat 38 provides stable support for the blank body 1, ensuring the stability of the forging process.

[0054] The lifting cylinder 37 is movably connected to the upper end of the forging table 2, the fixing seat 38 is welded inside the forging table 2, and the lifting cylinder 37 is slidably connected to the outer wall of the fixing seat 38.

[0055] A forging process for an anchor bolt foundation flange, the contents are as follows:

[0056] S1, place the blank body 1 to be forged on the fixed seat 38, then start the second motor 24, one half gear 16 starts to rotate, driving the other half gear 16 to rotate, and then the connecting rod 17 drives the two second rotating shafts 18 to move closer to each other, thereby driving the two connecting rods 4 20 to extend and move closer together, and the first clamping plate 21 completes the clamping of the side of the blank body 1;

[0057] S2, after the clamping is completed, the first cylinder 13 is started to drive the limit box 9 to move up and down, and then the forging head 3 is driven to forge the blank body 1. During the forging process, the two fourth cylinders 28 are started to extend so that the two second clamping plates 30 clamp the middle position of the blank body 1. At this time, the third motor 32 is started to drive the fourth cylinder 28 to rotate through the fourth gear 29 and the fifth gear 31, and then the second clamping plate 30 is used to drive the blank body 1 to reciprocate at a small angle, so that the blank body 1 is forged. The forging is more uniform. At the same time, during the forging process, when the forging head 3 hammers the blank body 1 downward, the two first clamping plates 21 clamp the blank body 1 and cooperate with the second clamping plates 30 to clamp the blank body 1, thereby increasing the stability of the forging head 3 when forging the blank body 1. When the forging head 3 moves upward, the first clamping plates 21 release the blank body 1, and the second clamping plates 30 drive the blank body 1 to rotate a certain angle, and then hammer the blank body 1 again, and this reciprocating cycle is repeated to complete the initial forging of the blank body 1.

[0058] S3, after the initial forging is completed, the fourth cylinder 28 is reset, the fifth cylinder 35 is started to drive the lifting cylinder 37 to rise out of the forging table 2, and at the same time, the second motor 24 drives the connecting rod 4 20 to reset and release the blank body 1, and the blank body 1 is placed in the lifting cylinder 37, and then the first motor 14 is started to drive the third gear 15 to rotate, thereby driving the second gear 8 and the first gear 7 to rotate, and the first gear 7 drives the extension column 42 to rotate to the meshing position of the first gear 7 and the second gear 8.
