Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to bearing ring forging equipment. Background Technology

[0002] As a fundamental component of precision machinery, the forging quality of bearing rings directly affects the bearing's load-bearing capacity and service life. In the forging process, the design of the demolding and lifting mechanism is particularly critical, ensuring that the formed workpiece experiences uniform stress during ejection to avoid deformation or surface damage caused by localized stress concentration.

[0003] A search revealed Chinese patent CN217252520U, which discloses a forging die for bearing rings, including a first die, a second die, and a lifting mechanism consisting of two symmetrically threaded tubes and threaded rods. This patent uses manual rotation of the symmetrically distributed threaded rods to drive a disc to eject the workpiece, thus avoiding surface dents during the forming process.

[0004] However, in practical applications, it was found that because only two symmetrical ejection points were set, the circumferential force on the annular workpiece was concentrated on both sides during demolding, resulting in a severely uneven distribution of ejection force. Specifically, this manifests as follows:

[0005] Local deformation and surface defects: When the ring bearing ring is demolded, the ejection force on both sides cannot evenly cover the entire circumference, and the workpiece is prone to radial warping or local depression, resulting in a decrease in surface smoothness.

[0006] Insufficient geometric adaptability: The symmetrical ejection structure is difficult to match the uniform demolding requirements of the ring-shaped workpiece. The adhesive stress between the workpiece and the mold cannot be dispersed circumferentially, and the residual internal stress after demolding is significant, affecting dimensional accuracy.

[0007] The aforementioned problems are particularly prominent in the mass production of high-precision bearing rings. There is an urgent need for a lifting mechanism that can achieve uniform circumferential force application in order to fundamentally solve the problem of workpiece deformation and surface damage caused by uneven distribution of ejection force in the existing technology. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model proposes a bearing ring forging equipment. By setting four sets of ejection holes in a ring on the bottom surface of the lower mold, and cooperating with multiple sets of moving rods to drive the top plate synchronously, the force distribution during the ejection process is uniform, which effectively avoids bearing ring deformation or surface damage caused by local stress concentration, and significantly improves the integrity and consistency of the formed workpiece.

[0009] The technical solution to achieve the purpose of this utility model is: a bearing ring forging and forming equipment, comprising:

[0010] A frame, the frame comprising a horizontally arranged base and a support column vertically fixed on the base;

[0011] A stamping drive module is detachably connected to the top of the base, which is vertically oriented directly above the support column;

[0012] The limiting frame is detachably connected to the top opening of the support column. The limiting frame includes a lower mold and fixing blocks on both sides of the lower mold. The top of the two fixing blocks is threadedly fixed with a second bolt between the top of the base and the corresponding top.

[0013] The lifting mechanism is located on the inner bottom surface of the processing groove. The inner bottom surface of the lower mold has an ejection hole that extends downwards. The lifting mechanism includes multiple sets of movable rods that pass through the ejection hole and the processing groove. The inner bottom surface of the processing groove is equipped with a servo motor for driving the movable rods to lift and adjust. The inner bottom surface of the lower mold is equipped with a top plate that matches the inner cross-section of the lower mold. The tops of the multiple sets of movable rods support the top plate corresponding to the bottom surface.

[0014] Anti-offset correction mechanism; an anti-offset correction mechanism for sliding up and down along the inner groove of the machining groove is provided between the servo motor device and the lower end of the moving rod.

[0015] In some embodiments, the anti-offset correction mechanism includes four sets of track baffles symmetrically installed vertically and parallel on the inner wall of the support column. A positioning slider is slidably connected between the four sets of track baffles. The bottom of the positioning slider is fixedly connected to the top output rod of the servo motor. The moving rod is a T-shaped screw, and a third bolt is threadedly connected to the bottom of the moving rod. The bottom of the moving rod is threadedly fixed to the top of the positioning slider by the third bolt.

[0016] In some embodiments, four sets of ejector holes are provided on the inner bottom surface of the lower mold, and the four sets of ejector holes are provided in a ring around the central axis on the inner bottom surface of the lower mold.

[0017] In some embodiments, the anti-offset correction mechanism further includes a connecting sleeve disposed at the bottom opening of the ejector hole, a fourth bolt threaded between the connecting sleeve and the bottom of the lower mold, and the body of the moving rod passing through the inside of the connecting sleeve.

[0018] In some embodiments, the stamping drive module includes a hydraulic stamping cylinder and an upper die connected to the bottom output rod of the hydraulic stamping cylinder. A connecting plate is welded to the top outer side of the hydraulic stamping cylinder, and a first bolt is threaded onto the connecting plate. The top of the lower die and the top of the support column are threaded together by the first bolt.

[0019] In some embodiments, the hollow region inside the processing groove extends through the front sidewall of the base.

[0020] In some embodiments, four sets of positioning blocks are installed on the inner bottom surface of the processing groove, and the outer casing of the servo motor is engaged with the four sets of positioning blocks.

[0021] Compared with existing technologies, the significant advantages of this invention are:

[0022] Firstly, this invention features four sets of ejection holes arranged in a ring on the bottom surface of the lower mold. These holes, combined with multiple sets of moving rods that synchronously drive the top plate, ensure that the top plate remains parallel to the inner wall of the lower mold during lifting and lowering. This completely eliminates defects such as localized deformation and surface dents in the bearing rings caused by uneven ejection forces on one side or symmetrically. Particularly for the geometric characteristics of ring bearing rings, this ring ejection structure effectively disperses the adhesive stress during forging demolding, ensuring that the formed workpiece does not experience radial displacement or axial twisting during ejection, significantly improving product dimensional accuracy and surface finish.

[0023] Secondly, this utility model innovatively adopts an anti-offset correction mechanism that combines track baffles and positioning sliders. Four sets of track baffles vertically guide the positioning slider, and the connecting sleeve provides secondary limiting for the moving rod, completely eliminating the risk of offset during the lifting process of the lifting mechanism, ensuring precise alignment between the top plate and the inner wall of the lower mold, thereby improving the stability and repeatability of the ejection action.

[0024] Thirdly, this utility model achieves modular assembly of key components such as the stamping drive module, limit frame, and moving rod through the first bolt, second bolt, third bolt, and fourth bolt. This not only simplifies the equipment disassembly and assembly process but also facilitates the quick replacement of molds and lifting mechanisms for bearing rings of different specifications, greatly improving equipment adaptability and maintenance efficiency.

[0025] Fourthly, this utility model has a through-type observation window on the front side wall of the base, which allows operators to directly monitor the real-time status of the lifting mechanism and the anti-deviation correction mechanism in the processing groove, making it easier to quickly troubleshoot abnormalities and reduce the risk of blind operation during equipment maintenance.

[0026] Fifthly, this utility model uses a servo motor to drive the lifting mechanism, replacing the traditional manual rotation of the threaded rod, to achieve automated control of the bearing ring ejection process. This reduces the intensity of manual labor and avoids uneven ejection force caused by improper operation. It solves the problems in the prior art, such as the lifting mechanism being prone to deviation leading to workpiece damage, uneven force affecting molding quality, cumbersome disassembly and maintenance steps, and low efficiency of manual operation.

[0035] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0036] This utility model provides an improved bearing ring forging equipment. The technical solution of this utility model is as follows:

[0037] like Figure 1 - Figure 5As shown, the bearing ring forging equipment includes: a frame 100, which includes a horizontally arranged base 101 and a support column 102 vertically fixed on the base 101; a stamping drive module, which is detachably connected to the top of the base 101 and faces vertically above the support column 102; a limiting frame, which is detachably connected to the top opening of the support column 102, the limiting frame including a lower die 3 and fixing blocks 301 on both sides of the lower die 3, with second bolts 302 threadedly fixed between the tops of the two fixing blocks 301 and the corresponding tops of the base 101; and a lifting mechanism, which is located at... The inner bottom surface of the processing groove 103 is provided with an ejection hole 303 extending downwards from the inner bottom surface of the lower mold 3. The lifting mechanism includes multiple sets of movable rods 5 passing through the ejection hole 303 and the processing groove 103. A servo motor 6 is provided on the inner bottom surface of the processing groove 103 to drive the movable rods 5 for lifting and adjusting. A top plate 4 adapted to the inner cross-section of the lower mold 3 is provided on the inner bottom surface of the lower mold 3. The top of the multiple sets of movable rods 5 supports the top plate 4 corresponding to the bottom surface. An anti-offset correction mechanism is provided between the servo motor 6 and the lower end of the movable rods 5 for sliding up and down along the inner groove of the processing groove 103.

[0038] like Figure 1 , Figure 3 as well as Figure 4 As shown, in one embodiment, the anti-deviation correction mechanism includes four sets of track baffles 9 symmetrically installed vertically and parallel on the inner wall of the support column 102. Positioning sliders 7 are slidably connected between the four sets of track baffles 9. The bottom of the positioning sliders 7 is fixedly connected to the top output rod of the servo motor 6. The moving rod 5 is a T-shaped screw, and a third bolt 502 is threadedly connected to the bottom of the moving rod 5. The bottom of the moving rod 5 is threadedly fixed to the top of the positioning slider 7 by the third bolt 502. Through the arrangement of the four sets of track baffles 9, positioning sliders 7, third bolts 502, and the T-shaped screw of the moving rod 5, the moving rod 5 can slide along the direction of the track baffles 9 during its up-and-down movement. The positioning sliders 7 serve as guides and limiters, preventing the moving rod 5 from deviating during movement, thereby ensuring the stability and accuracy of the lifting mechanism. Simultaneously, the threaded fixing method facilitates the installation and disassembly of the moving rod 5.

[0039] In one embodiment, four sets of ejector holes 303 are formed on the inner bottom surface of the lower mold 3, and these four sets of ejector holes 303 are arranged in a ring around the central axis on the inner bottom surface of the lower mold 3. By setting four sets of ejector holes 303 in a ring around the central axis on the inner bottom surface of the lower mold 3, a uniform force can be applied to the top plate 4 during ejection, allowing the top plate 4 to smoothly eject the machined bearing ring. This avoids damage to the bearing ring due to uneven force and improves product quality.

[0040] like Figure 3 and Figure 4 As shown, in one embodiment, the anti-deviation correction mechanism further includes a connecting sleeve 503 disposed at the bottom opening of the ejection hole 303. A fourth bolt 504 is threadedly connected between the connecting sleeve 503 and the bottom of the lower mold 3, and the rod body of the movable long rod 5 passes through the interior of the connecting sleeve 503. The connecting sleeve 503 and the fourth bolt 504 further limit and guide the movable long rod 5 at the ejection hole 303, making the movable long rod 5 more stable when moving up and down. This also facilitates the connection and disassembly of the movable long rod 5 and the lower mold 3, enhancing the overall stability of the equipment.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, the stamping drive module includes a hydraulic stamping cylinder 2 and an upper die 201 connected to the bottom output rod of the hydraulic stamping cylinder 2. A connecting plate 202 is welded to the outer top of the hydraulic stamping cylinder 2, and a first bolt 203 is threaded onto the connecting plate 202. The top of the lower die 3 is threadedly connected to the top of the support column 102 through the first bolt 203. Through the arrangement of the hydraulic stamping cylinder 2, the upper die 201, the connecting plate 202, and the first bolt 203, the hydraulic stamping cylinder 2 can be stably mounted on the frame 100, and the output rod of the hydraulic stamping cylinder 2 drives the upper die 201 to perform stamping work. The threaded connection facilitates the installation and disassembly of the stamping drive module, while also ensuring stability and reliability during the stamping process.

[0042] like Figure 1 , Figure 3 and Figure 5As shown, in one embodiment, the hollow area inside the processing groove 103 penetrates the front wall of the base 101. The lifting and lowering status of the anti-deviation correction mechanism and the lifting mechanism inside the processing groove 103 can be directly observed through this penetration. By having the hollow area inside the processing groove 103 penetrate the front wall of the base 101, operators can directly observe the lifting and lowering status of the anti-deviation correction mechanism and the lifting mechanism inside the processing groove 103. This facilitates real-time monitoring of the equipment's operation, timely detection and adjustment of problems, and improves the safety and efficiency of the equipment.

[0043] like Figure 1 and Figure 3 As shown, in one embodiment, four sets of positioning blocks 8 are installed on the inner bottom surface of the processing groove 103. The outer shell of the servo motor 6 is engaged with the four sets of positioning blocks 8. By setting four sets of positioning blocks 8 inside the processing groove 103, when the servo motor 6 is installed on the inner bottom surface of the processing groove 103, the outer shell is limited and fixed by the corresponding positioning blocks 8. This not only facilitates the installation of the servo motor 6 on the inner bottom surface of the processing groove 103, but also provides a stable limiting effect to prevent shaking. Through the setting of four sets of positioning blocks 8, the servo motor 6 can be quickly and accurately installed on the inner bottom surface of the processing groove 103. Furthermore, the four sets of positioning blocks 8 limit and fix the outer shell of the servo motor 6, preventing the servo motor 6 from shaking during operation. This ensures the stability and accuracy of the servo motor 6 driving the moving rod 5 for lifting and adjusting, and extends the service life of the servo motor 6.

[0044] The working principle and usage process of this utility model are as follows: First, the bearing ring material to be forged is placed on the lower mold 3. Then, the hydraulic stamping cylinder 2 is started, and the output rod of the hydraulic stamping cylinder 2 drives the upper mold 201 to move downward, stamping and forging the bearing ring material. During the stamping process, the anti-deviation correction mechanism ensures the stability of the lifting mechanism and prevents the moving rod 5 from deviating. After the stamping is completed, the servo motor 6 is started, and the servo motor 6 drives the moving rod 5 to rise, which in turn drives the top plate 4 to rise, ejecting the processed bearing ring from the lower mold 3. Since the hollow area inside the processing groove 103 penetrates the front wall of the base 101, the operator can observe the lifting status of the anti-deviation correction mechanism and the lifting mechanism in real time, ensuring the normal operation of the equipment. When it is necessary to maintain the equipment or replace parts, the components can be disassembled and installed using the corresponding bolts (such as the first bolt 203, the second bolt 302, the third bolt 502, the fourth bolt 504, etc.).

[0045] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
