[0015] Compared with the prior art, the beneficial effects of this utility model are: the bearing ring forging mechanism not only facilitates the cleaning of dust and impurities and the protection of the controller, but also facilitates the movement of the cleaning frame;

[0016] (1) The exhaust fan is equipped with a fan, filter screen, storage drawer, connecting pipe, hose, cleaning rack and dust removal port.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A bearing ring forging mechanism includes a forging machine body 1, with support frames 16 fixedly connected to both sides of the top of the forging machine body 1, a hydraulic cylinder 19 installed at the bottom of the support frame 16, a presser 17 installed at the bottom of the hydraulic cylinder 19, a worktable 23 provided at the top of the forging machine body 1, and a cleaning structure provided on the left side of the support frame 16 and the top of the worktable 23.

[0026] The cleaning structure includes an exhaust fan 12, a hose 21, and a cleaning frame 22. A housing 11 is fixedly connected to the bottom left side of the support frame 16. An exhaust fan 12 is installed at the bottom inside the housing 11. A storage drawer 14 is provided inside the housing 11. A filter screen 13 is provided at the bottom inside the storage drawer 14 and at the top of the exhaust fan 12. A cleaning frame 22 is provided on the left side of the top of the workbench 23. A dust removal port 26 is opened inside the cleaning frame 22. A connecting pipe 15 is provided between the cleaning frame 22 and the housing 11. A hose 21 is fixedly connected between the connecting pipes 15.

[0027] The two sides of the connecting pipe 15 pass through the interior of the housing 11 and the cleaning rack 22 respectively. The right side of the connecting pipe 15 is located at the top of the dust removal port 26. Storage boxes 24 are provided on both sides of the workbench 23. A cleaning sponge is provided at the bottom of the cleaning rack 22.

[0028] Furthermore, the top surface of the worktable 23 is provided with an annular boss that matches the pressing surface of the presser 17. The outer diameter of the boss is consistent with the inner diameter of the annular groove of the presser 17, and the height is adapted to the inner hole height of the ring. When the hydraulic cylinder 19 drives the presser 17 to press down, the annular boss of the worktable 23 and the annular groove of the presser 17 form an enclosed space, pressing the metal blank placed outside the boss into an annular ring blank. The excess metal of the blank will be squeezed into the gap between the presser 17 and the worktable 23, and finally forming a semi-finished product that conforms to the basic outline of the bearing ring.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the exhaust fan 12 is turned on, the exhaust fan 12 adsorbs the dust on the top of the workbench 23 through the connecting pipe 15 and the dust removal port 26, preventing dust from adhering to the bearing rings during the processing of the bearing rings. The bottom of the cleaning rack 22 can clean solid impurities, so that the impurities are cleaned into the inside of the storage box 24, preventing the impurities from being unable to be adsorbed and affecting the use. The adsorbed dust will fall into the inside of the storage drawer 14.

[0030] A controller 6 is provided on the left side of the front end of the forging machine body 1. A fixed plate 2 is fixedly connected to the front end of the forging machine body 1. A connecting plate 7 is fixedly connected to the left edge of the front end of the forging machine body 1. Limit rods 4 are fixedly connected to the upper and lower ends between the fixed plate 2 and the connecting plate 7. A corrugated cover 3 is fixedly connected to the left side of the fixed plate 2. A movable plate 29 is fixedly connected to the left side of the corrugated cover 3. Limit blocks 5 are fixedly connected to the upper and lower ends of the left side of the front end of the forging machine body 1. Magnetic blocks 28 are fixedly connected to the front ends of the connecting plate 7 and the movable plate 29 respectively. Two sets of magnetic blocks 28 are provided. The magnetic blocks 28 cooperate with each other. The upper and lower ends inside the movable plate 29 slide outside the limit rods 4.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, the movable plate 29 is fixed to one side of the connecting plate 7 by the magnetic block 28, so that the corrugated cover 3 can protect the controller 6 and prevent the controller 6 from being damaged due to prolonged exposure. When the controller 6 needs to be used, the movable plate 29 is pulled to slide outside the limit rod 4, so that the corrugated cover 3 is moved away from the front end of the controller 6 to prevent the corrugated cover 3 from blocking the controller 6 and affecting its use. The limit rod 4 can limit the movable plate 29.

[0032] Limiting sleeves 20 are installed on both sides of the top of the presser 17. Limiting sleeves 18 are installed on both sides of the top of the support frame 16. The limiting sleeves 18 are sleeved on the outside of the limiting sleeves 20. A protective shell 9 is installed at the front end of the top of the forging machine body 1. A servo motor 8 is installed on the left side of the protective shell 9. A threaded rod 25 is fixedly connected to the output end of the servo motor 8. A threaded sleeve 10 is provided on the outside of the threaded rod 25. A fixing frame 27 is fixedly connected to the top of the threaded sleeve 10. The fixing frame 27 is fixedly connected to the front end of the cleaning frame 22. The threaded sleeve 10 and the threaded rod 25 cooperate with each other.

[0033] Furthermore, for bearing rings with raceways, the presser 17 can be adapted by replacing the pressing surface module. The lower pressing surface of the presser 17 adopts a detachable design. When it is necessary to forge a ring with raceways, only the pressing surface module with raceway grooves needs to be replaced.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, when the hydraulic cylinder 19 drives the presser 17 to rise and fall, the limit sleeve 20 will slide up and down inside the limit sleeve 18, thereby improving the stability of the presser 17. When cleaning impurities, the servo motor 8 is started, and the servo motor 8 drives the threaded rod 25 to rotate, so that the threaded sleeve 10 outside the threaded rod 25 drives the cleaning frame 22 to move left and right at the top of the worktable 23 through the fixed frame 27, thereby further cleaning the impurities at the top of the worktable 23.

[0035] Working principle:

[0036] When in use, the pre-treated metal billet is placed on the outside of the annular boss of the worktable 23, ensuring that the center of the billet is aligned with the center of the boss. The pressing pressure and pressing stroke of the presser 17 are set by the controller 6, and the exhaust fan 12 and servo motor 8 are started. The dust and oxide scale on the surface of the worktable 23 are adsorbed through the dust removal port 26 of the cleaning rack 22 to avoid impurities affecting the forming quality of the billet.

[0037] The hydraulic cylinder 19 is activated by the controller 6, which pushes the presser 17 downward. At this time, the limiting sleeve 20 slides along the limiting sleeve 18 to ensure that the presser 17 presses down accurately. When the annular groove of the presser 17 contacts the blank with the annular boss of the worktable 23, the pressing force is evenly applied to the circumference of the blank, pressing the round blank into an annular ring blank. After the presser 17 presses down to the set stroke, it maintains the pressure for 3-5 seconds to ensure that the blank is fully deformed and to avoid springback. After forging is completed, the hydraulic cylinder 19 drives the presser 17 to reset upward, and the limiting sleeve 20 rises synchronously along the limiting sleeve 18. At this time, the annular ring blank can be directly removed from the annular boss of the worktable 23, completing one forging cycle.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
