Description

Technical Field

[0001] This invention relates to the field of bearing processing equipment, and more specifically, to a bearing forging preforming forging equipment. Background Technology

[0002] As a key mechanical component, the performance and lifespan of bearing rings largely depend on the forging quality of the blank. Forging is the first important process in the manufacturing of bearing rings, aiming to obtain a pre-formed blank with reasonable metal flow lines, dense microstructure, and a shape close to that of the part, laying the foundation for subsequent processing. Traditional pre-forming forging of bearing rings, especially for processes that require local end face hammering to initially distribute the metal volume and form a specific contour, often uses an integral mold or a simple ring clamp for fixing and rotating.

[0003] For example, the patent with authorization announcement number CN117920921B and announcement date of December 20, 2024 discloses a bearing ring forging die. When hammer forging its end face, it uses an internal support clamp to hold the inner wall of the bearing ring. However, the clamping block and the inner wall of the bearing ring are in an elastic clamping state. During the local hammer forging process, the axial height of the forged area decreases and the radial thickness increases, which will cause the inner diameter of the bearing ring to decrease locally in this area. The clamping block shrinks under the elastic action. When hammer forging the end face of other positions of the bearing ring, the radial thickness cannot be controlled, resulting in inconsistent thickness of the bearing ring after overall forging, and the bearing ring is an irregular circle. Summary of the Invention

[0004] This invention provides a preforming forging equipment for bearing forgings, which solves the technical problem in related technologies where the thickness of bearing rings after forging is inconsistent due to the drop in forging temperature, which leads to the failure of clamping and unreliable indexing. At the same time, it avoids the bottom of the bearing rings sticking to the worktable and being scratched during rotation.

[0005] This invention provides a preforming forging equipment for bearing forgings, including a machine body and an operating table. The operating table is connected to the machine body, and a clamping mechanism and bearing rings are installed on the operating table. The bearing rings are horizontally arranged on the upper surface of the operating table. The clamping mechanism includes a mounting base, an inner clamping block, an outer clamping block, and a movable arm. The mounting base is driven to rotate on the operating table. A support base is mounted on the mounting base and is driven to move radially on the mounting base. One end of the movable arm is rotatably connected to the inner clamping block, and the other end is rotatably connected to the support base. The outer clamping block is mounted on the mounting base. A locking block is installed inside the inner clamping block. A slot is opened at the end of the movable arm near the inner clamping block. The locking block is driven to move vertically up and down within the inner clamping block. The locking block and the slot form a limiting and abutting engagement.

[0006] In a preferred embodiment, the machine body includes a frame, inside which a forging assembly is provided, and at the bottom of the forging assembly is a forging head for hammer forging the end face of the bearing ring.

[0007] In a preferred embodiment, the forging head is located directly above the end face of the bearing ring held by the inner and outer clamping blocks.

[0008] In a preferred embodiment, the stabilizing component includes a mounting base installed on one side of the top of the operating table, with a stabilizing clamp block movably connected to one side of the mounting base by bolts, and the stabilizing clamp block being connected to the outer wall of the bearing race.

[0009] In a preferred embodiment, a first fixed frame is connected to one side of the support base, and transmission gears are provided at the rotatable connection points of the movable arm, the inner clamping block, and the support base. The transmission gears on the two sets of movable arms mesh with each other, and an electric push rod is installed inside the inner clamping block. The output end of the electric push rod is connected to a locking block.

[0010] In a preferred embodiment, the clamping mechanism further includes a telescopic cylinder, a connecting rod, a slide bar, a sliding plate, a micro motor, and a connecting plate. The telescopic cylinder is connected to the top of the mounting base, and the output end of the telescopic cylinder is connected to the support base via the connecting rod. A rectangular support groove is provided inside the mounting base, and a locking block is movably disposed inside the rectangular support groove. A threaded hole is provided on one side of the top of the locking block, and a lead screw is threaded into the threaded hole. The top end of the lead screw is fixedly connected to the bottom output end of the micro motor. One side of the micro motor is installed on one side of the slide bar, and the slide bar is slidably disposed in the mounting groove provided inside the support base. The slide bar is sleeved on the periphery of the sliding plate, and elastic elements are respectively provided on the upper and lower sides of the sliding plate. One end of the elastic element is connected to the inner wall of the mounting groove, and the other end is connected to the outer side of the slide bar. The bottom of the slide bar is movably connected to the locking block via the connecting plate.

[0011] In a preferred embodiment, the mounting base has an internal mounting chamber, and a linkage component is provided inside the mounting chamber. The linkage component includes a fixed gear and a connecting block. The fixed gear is installed at the center of the mounting chamber, and racks are meshed on both sides of the fixed gear. One rack passes through the top of the mounting base and is fixedly connected to the bottom of the first fixing frame, and the other rack is fixedly connected to the connecting block. The connecting block passes through the top of the mounting base and is fixedly connected to the bottom of the outer clamping block. The mounting bases at the bottom of the first fixing frame and the outer clamping block both have rectangular holes that communicate with the mounting chamber.

[0012] In a preferred embodiment, a fan-shaped groove is provided on the top of the mounting base, the fan-shaped groove communicates with the mounting chamber, and the fan-shaped groove is located between the inner clamping block and the outer clamping block. A lifting platform is movably connected inside the fan-shaped groove, and springs are respectively installed on both sides of the bottom of the lifting platform.

[0013] In a preferred embodiment, two sliding grooves are provided at the bottom of the lifting platform, and support sliders are slidably arranged inside the sliding grooves. Both support sliders are fixedly connected to both ends of the connecting block.

[0014] In a preferred embodiment, the groove has a rectangular cross-sectional shape, and the top side of the supporting slider is a slope for sliding and fitting the groove.

[0015] The beneficial effects of this invention are as follows: 1. This invention uses a clamping mechanism to actively lock the clamp position after forging. Even if the bearing ring shrinks due to material cooling, the clamp can still maintain effective clamping force, ensuring the reliability of indexing rotation and avoiding process interruption or decrease in accuracy due to clamping failure.

[0016] 2. The present invention uses a linkage component to lower the support platform before indexing, so that the bottom surface of the bearing ring is separated from the platform, which effectively avoids the adhesion phenomenon under high temperature and high pressure, prevents scratching of the formed surface during rotation, and improves the surface quality of the forging.

[0017] 3. The present invention can dynamically adjust the clamping force according to the actual thickness of the bearing ring through the clamping mechanism. Even if the thickness after forging does not reach the preset value, it can still achieve effective clamping and adapt to the forging requirements under different materials and process conditions.

[0018] 4. The present invention uses a support base that is locked to the mounting base by a locking block to withstand the forging impact force, thereby preventing the impact from being transmitted to the telescopic cylinder and other actuators, and extending the service life of the equipment.

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10 A bearing forging preforming forging equipment includes a machine body 1 and an operating table 2. The operating table 2 is connected to the machine body 1. A clamping mechanism 4 and a bearing ring 6 are installed on the operating table 2. The bearing ring 6 is horizontally arranged on the upper surface of the operating table 2. The clamping mechanism 4 includes a mounting base 401, an inner clamping block 417, an outer clamping block 418, and a movable arm 413. The mounting base 401 is driven to rotate on the operating table 2. A support base 404 is mounted on the mounting base 401 and is driven to move radially on the mounting base 401. One end of the movable arm 413 is rotatably connected to the inner clamping block 417, and the other end is rotatably connected to the support base 404. The outer clamping block 418 is mounted on the mounting base 401. A locking block 416 is installed inside the inner clamping block 417. A slot is provided at one end of the movable arm 413 near the inner clamping block 417. The locking block 416 is driven to move vertically up and down within the inner clamping block 417. The locking block 416 and the slot form a limiting and abutting engagement.

[0033] It should be further explained that the center of the bearing ring 6 is on the same vertical axis as the hinge point of the mounting base 401 and the operating table 2. The operating table 2 is fixed inside the machine body 1 and is used to support and position the workpiece. One end of the mounting base 401 is hinged to the top of the operating table 2 and is driven by a drive source, which can rotate around the hinge point. In this embodiment, the drive source is installed inside the operating table 2 and can be a motor, rotary cylinder or other rotary drive mechanism. When the clamping mechanism 4 completes the clamping of the bearing ring 6 and the end face of the corresponding clamping position is forged for the first time, the locking block 416 locks the movable arm 413, so that the inner clamping block 417 cannot move radially through the movable arm 413. The drive source drives the mounting base 401 to rotate a certain angle, which drives the bearing ring 6 to rotate synchronously. After rotation, the clamping mechanism 4 releases the bearing ring 6 and is reset to the original angle by rotating the mounting base 401 again, clamping and supporting the unforged end face of the bearing ring 6.

[0034] like Figure 5 As shown, a first fixed frame 412 is connected to one side of the support base 404. Transmission gears 414 are provided at the rotatable connection points of the movable arm 413, the inner clamping block 417, and the support base 404. The transmission gears 414 on the two sets of movable arms 413 mesh with each other. An electric push rod 415 is installed inside the inner clamping block 417. The output end of the electric push rod 415 is connected to the locking block 416. In this embodiment, the tooth groove on the transmission gear 414 is the slot at one end of the movable arm 413, that is, the locking block 416 engages with the transmission gear 414 through the tooth groove.

[0035] It should be further explained that when the inner clamping block 417 is compressed by the radial section pressure, or when the mounting base 401 drives the inner clamping block 417 to rotate, the movable arm 413 can provide stable support for the inner clamping block 417. Since the transmission gear 414 is locked by the locking block 416, the transmission gear 414 will not rotate. The movable arm 413 moves synchronously through the meshing of the transmission gear 414, which will not cause the inner clamping block 417 to be tilted by force, and it will always be in a parallel state with the first fixed frame 412.

[0036] In this embodiment, during the first forging process or immediately after forging, the inner wall of the bearing ring 6, due to the increase in wall thickness, presses inward against the inner clamping block 417. The inner clamping block 417, subjected to radial pressure, transmits the force to the movable arm 413 hinged to it. Multiple movable arms 413 mesh with each other through the transmission gears 414 at their ends. When the inner clamping block 417 is compressed, it forces the movable arm 413 to rotate around its hinge point, and the transmission gear 414 meshes and rotates accordingly. When one forging is completed and it is necessary to maintain the current clamping state for indexing rotation, the electric push rod 415 is activated. The electric push rod 415 pushes the locking block 416 downward, precisely inserting it into the currently engaged state. Once the locking block 416 is inserted between the teeth of the two transmission gears 414, it mechanically locks the rotational freedom of the transmission gears 414, thereby locking the hinged state of all movable arms 413. This prevents the inner clamping block 417 from retracting radially. At this time, the inner clamping block 417 is actively locked in its current position. Even if the inner diameter of the forging area of ​​the bearing ring 6 slightly increases due to temperature drop and material shrinkage, the inner clamping block 417 will not loosen. This ensures that the inner wall of the bearing ring 6 is always effectively supported. This completely solves the problem of the clamping force of the fixture failing due to material cooling and shrinkage, which prevents the bearing ring 6 from rotating and indexing reliably.

[0037] Initially, the arc-shaped outer wall of the inner clamping block 417 is attached to the inner wall of the bearing ring 6, and the locking block 416 is located directly above the two meshing transmission gears 414, but does not lock the transmission gears 414. During the forging process of the bearing ring 6, the radial thickness of the part of the bearing ring 6 being hammered increases, gradually pressing the inner clamping block 417 towards the position of the first fixed frame 412, and the movable arm 413 rotates between them. During this process, the inner clamping block 417 is always attached to the inner wall of the bearing ring 6 until the first forging of the bearing ring 6 is completed. Then, the electric push rod 415 is activated to control the locking block 416 to move downward and lock the two meshing transmission gears 414. After locking is completed, the subsequent hammering locking block 416 will always lock the transmission gears 414. To prevent changes in the distance between the inner clamping block 417 and the first fixed frame 412, a torsion spring or a drive motor can be installed at the connection between the transmission gear 414 and the inner clamping block 417. After the bearing ring 6 is forged, the locking block 416 is released, and the torsion spring, under its elastic action, or the drive motor, drives the inner clamping block 417 to move, so that the distance between the inner clamping block 417 and the first fixed frame 412 returns to the initial state. This structure solves the problem of poor elasticity control between the clamping block and the inner wall of the bearing ring 6. During the initial forging, the thickness of the inner diameter of the bearing ring 6 is determined in subsequent forging, so that the thickness of the inner diameter of the bearing ring 6 is consistent after being hammered, avoiding the situation where the bearing ring 6 is irregularly round due to inconsistent forging thickness.

[0038] The machine body 1 includes a frame 101, and a forging assembly 102 is provided inside the frame 101. A forging head 103 for hammer forging the end face of the bearing ring 6 is installed at the bottom of the forging assembly 102. The forging head 103 is used to perform partial hammer forging on the end face of the bearing ring 6. The forging head 103 is located directly above the end face of the bearing ring 6 where it is held by the inner clamping block 417 and the outer clamping block 418. In this embodiment, the forging assembly 102 is the driving mechanism that drives the forging head 103 to descend. The forging assembly 102 can be a hydraulic cylinder or the like.

[0039] The stabilizing component 3 includes a fixed base 301 mounted on one side of the top of the operating table 2. A stabilizing clamp 303 is movably connected to one side of the fixed base 301 via bolts 302. The stabilizing clamp 303 is attached to the upper end face of the bearing ring 6. By loosening the bolts 302, the stabilizing clamp 303 is moved so that its arc-shaped working surface is attached to the outer circumferential surface of the bearing ring 6. Then, the bolts 302 are tightened to lock the stabilizing clamp 303 onto the operating table 2 via the fixed base 301. This operation provides radial constraint to the bearing ring 6, preventing it from shifting or rotating accidentally during forging. At the same time, it ensures that it can perform precise indexing rotation under the drive of the clamping mechanism 4. In other words, in this embodiment, the stabilizing clamp 303 is only attached to the upper surface of the bearing ring 6, and the friction between the two is small. Therefore, the setting of the stabilizing clamp 303 will not affect the rotation of the bearing ring 6 driven by the mounting base 401.

[0040] In the above embodiments, see Figure 2 , Figure 4 , Figure 6 as well as Figure 10 When the forging head 103 forges the bearing ring 6 downwards, it applies radial forging pressure to the bearing ring 6. Therefore, under continuous forging, the forging pressure borne by the bearing ring 6 will be transmitted to the telescopic cylinder 402 in the clamping mechanism 4. Under such forging impact load, the telescopic cylinder 402 may suffer irreversible mechanical damage to its core components. Therefore, in order to solve this technical problem, in another embodiment of the present invention, a rectangular support groove is provided inside the mounting base 401, and a locking block 410 is movably arranged inside the rectangular support groove. The top of the locking block 410 is connected to the support base 404.

[0041] In this embodiment, it should be noted that, in the initial state, the inner clamping block 417 is attached to the inner side of the bearing ring 6, the support seat 404 is located above the rectangular support groove, and the locking block 410 is locked inside the rectangular support groove. When the movable arm 413 limits the radial forging thickness of the bearing ring 6 through the locking block 416, the inner clamping block 417 is locked, and the distance between the inner clamping block 417 and the first fixed frame 412 no longer changes. Therefore, when the forging head 103 forges the bearing ring 6 downward, the radial thickness of the bearing ring 6 gradually increases, and the inner wall contacts the arc-shaped outer wall of the inner clamping block 417. At this time, the radial pressure borne by the bearing ring 6 is transmitted to the support seat 404 through the inner clamping block 417. Since the support seat 404 is embedded in the rectangular support groove through the locking block 410, the radial impact force generated by forging is transmitted to the support seat 404 and borne by it. The telescopic cylinder 402 fixed on the other side of the support seat 404 is thus isolated from the radial impact force and protected.

[0042] In the above embodiments, see Figure 6 , Figure 7 , Figure 10 as well as Figure 11 During the continuous forging process of the bearing ring 6, the temperature of the bearing ring 6 continuously decreases, and the material deformation resistance increases. When using fixed forging parameters and fixture positioning, it is difficult to ensure that the radial thickness obtained at each forging station is consistent. This may result in the radial forging thickness of the bearing ring 6 not reaching the limit thickness of the clamping mechanism 4. Therefore, in order to solve this technical problem, in another embodiment of the present invention, the clamping mechanism 4 further includes a telescopic cylinder 402, a connecting rod 403, a slide bar 405, a sliding plate 407, a micro motor 408, and a connecting plate 411. The telescopic cylinder 402 is connected to the top of the mounting base 401, and the output end of the telescopic cylinder 402 is connected to the support base 404 through the connecting rod 403. The part has a rectangular support groove, and a locking block 410 is movably installed inside the rectangular support groove. A threaded hole is opened on one side of the top of the locking block 410, and a lead screw 409 is threadedly connected inside the threaded hole. The top of the lead screw 409 is fixedly connected to the bottom output end of the micro motor 408. One side of the micro motor 408 is installed on one side of the slide bar 405. The slide bar 405 is slidably installed in the mounting groove opened inside the support base 404. The slide bar 405 is sleeved on the periphery of the sliding plate 407, and elastic elements 406 are respectively provided on the upper and lower sides of the sliding plate 407. One end of the elastic element 406 is connected to the inner wall of the mounting groove, and the other end is connected to the outer side of the slide bar 405. The bottom of the slide bar 405 is movably connected to the locking block 410 through the connecting plate 411.

[0043] It should be further explained that when the mounting base 401 is rotated, since the inner clamping block 417 and the outer clamping block 418 cannot hold the bearing ring 6, the rotation of the mounting base 401 cannot drive the bearing ring 6 to rotate together. At this time, the telescopic cylinder 402 is activated to push the support base 404, so that the support base 404 pushes the inner clamping block 417 to slide until the inner clamping block 417 clamps the radial inner wall of the bearing ring 6. During this process, the elastic element 406 is compressed, the slide bar 405 slides on the surface of the sliding plate 407, and the locking block 410 is still locked inside the rectangular support groove. In this embodiment, the elastic element 406 can be a spring, an elastic plate, etc.

[0044] When the mounting base 401 rotates the bearing ring 6 to a preset angle, the telescopic cylinder 402 and the micro motor 408 start simultaneously. The telescopic cylinder 402 drives the support base 404 to retract, moving it closer to the telescopic cylinder 402. The micro motor 408 drives the lead screw 409 to rotate, causing the locking block 410 to slide from inside the rectangular support groove into the mounting groove inside the support base 404. Because the locking block 410 disengages from the rectangular support groove, the retracted distance of the support base 404 is longer than the previous extended distance. Furthermore, when the locking block 410 is no longer constrained by the rectangular support groove, the elastic element 406 resets, causing the slide bar 405 to slide back to its original position. At this time, the mounting base 401 is rotated in the opposite direction, so that the mounting base 401 is reset to its original angle position. Then, the telescopic cylinder 402 is activated to push the support base 404 and the inner clamping block 417, so that the locking block 410 at the bottom of the support base 404 is locked back into the rectangular support groove. The distance between the inner clamping block 417 and the outer clamping block 418 is still the radial limiting thickness of the bearing ring 6.

[0045] In the above embodiments, see Figure 8 , Figure 9 and Figure 10 During indexing rotation, the bottom end face of the bearing ring 6 may stick to the lower worktable due to high temperature and pressure. Forcing rotation will scratch the already formed working surface, affecting the quality of the forging. However, if all clamps are completely released to eliminate the sticking, the indexing reference is lost, making the operation cumbersome and inefficient. Therefore, to solve this problem, in another embodiment of the present invention, the mounting base 401 has a mounting chamber inside, and a linkage component 5 is provided inside the mounting chamber. The linkage component 5 includes a fixed gear 502 and a connecting block 503. The fixed gear 502 is installed at the center of the installation chamber. The fixed gear 502 has racks 501 meshing on both sides. One rack 501 passes through the top of the mounting base 401 and is fixedly connected to the bottom of the first fixing frame 412. The other rack 501 is fixedly connected to the connecting block 503. The connecting block 503 passes through the top of the mounting base 401 and is fixedly connected to the bottom of the outer clamping block 418. The mounting bases 401 at the bottom of the first fixing frame 412 and the outer clamping block 418 are both provided with rectangular holes and are connected to the installation chamber.

[0046] It should be further explained that when the bearing ring 6 cannot reach the radial thickness of the forging target due to cooling, the telescopic cylinder 402 is activated to push the support base 404 and the inner clamping block 417 to move towards the bearing ring 6. The inner clamping block 417 clamps the inner wall of the bearing ring 6. When the support base 404 moves, it drives the fixed gear 502 to rotate through the rack 501 connected to the bottom, thereby forcing the other rack 501 to move, thereby driving the outer clamping block 418 to move towards the bearing ring 6 until the outer clamping block 418 clamps the outer wall of the bearing ring 6. At this time, the inner clamping block 417 and the outer clamping block 418 clamp the inner and outer walls of the bearing ring 6 at the same time. Therefore, when the mounting base 401 rotates, it can drive the bearing ring 6 to rotate together.

[0047] The mounting base 401 has a fan-shaped groove 508 on its top, which communicates with the mounting chamber and is located between the inner clamping block 417 and the outer clamping block 418. A lifting platform 505 is movably connected inside the fan-shaped groove 508. Springs 507 are installed on both sides of the bottom of the lifting platform 505. Two sliding grooves 506 are opened at the bottom of the lifting platform 505. Support sliders 504 are slidably arranged inside the sliding grooves 506. Both support sliders 504 are fixedly connected to both ends of the connecting block 503. The cross-sectional shape of the sliding groove 506 is rectangular. One side of the top of the support slider 504 is inclined to slide and adapt to the sliding groove 506.

[0048] In this embodiment, it should be further explained that the top of the lifting platform 505 is used to support the forging end face area of ​​the bearing ring 6. When the lifting platform 505 is lifted by the support slider 504, the spring 507 at its bottom is in a stretched state. After a part of the end face of the bearing ring 6 is forged, the mounting base 401 drives the bearing ring 6 to rotate. After the rotation is completed, the mounting base 401 needs to retract a certain distance. At this time, the support base 404 and the first fixed frame 412 retract simultaneously, causing the rack 501 connected to one end of the bottom of the first fixed frame 412 to slide linearly towards the center of the mounting base 401. Under the action of the fixed gear 502, the other rack 501 is driven to slide linearly away from the circular direction of the mounting base 401. At this time, the two support sliders 504 located in the bottom groove 506 of the lifting platform 505 gradually leave the interior of the groove 506. Since one side of the top of the support slider 504 is inclined, when the top plane of the support slider 504 completely leaves the groove 506... After entering the slide groove 506, the support slider 504 continues to slide outward, and the lifting platform 505 is no longer supported. Under the elastic action of multiple springs 507 at the bottom, the lifting platform 505 is pulled downward and slides towards the bottom of the fan-shaped groove 508. Since the other end of the bearing ring 6 is stably pressed down and fixed by the stabilizing clamp 303, the bearing ring 6 does not move when the lifting platform 505 slides downward. The part of the lifting platform 505 that is stuck to the bottom end face of the bearing ring 6 is separated. The part of the bottom of the lifting platform 505 that contacts the bottom end face of the bearing ring 6 is roughened.
