Description

Technical Field

[0001] This invention belongs to the field of bearing forging, specifically a ball bearing steel forging device and its forging process. Background Technology

[0002] Forging of ball bearings refers to the process of forming bearing ring blanks using forging technology during the manufacturing of ball bearings. Forging is a metal forming process that involves heating a metal billet to a certain temperature and then using pressure to cause it to undergo plastic deformation, thereby obtaining a workpiece of the required shape and size. In the production of ball bearings, the forging process is very critical, as it not only affects the reliability and lifespan of the bearing, but also directly affects the utilization rate of raw materials and production costs.

[0003] Patent CN114178460A discloses a forging process and forging apparatus for roller bearing components. The apparatus includes a workbench mounted above a mounting platform, with cleaning boxes symmetrically arranged on both sides of the workbench. The cleaning boxes are bolted to the mounting platform, and the cleaning boxes penetrate the mounting platform. A telescopic box is located on one side of the cleaning box. A first telescopic pipe and a second telescopic pipe are respectively arranged between the cleaning box and the telescopic box. The first telescopic pipe is positioned above the second telescopic pipe, and both the first and second telescopic pipes are fixedly connected to the cleaning box and the telescopic box, respectively. The telescopic box contains a ventilation chamber and a cleaning chamber.

[0004] During the forging process described above, the edges of the bearing steel will rapidly oxidize due to compression and high temperature, resulting in oxide scale. If the oxide scale is not cleaned, it will be squeezed into the bearing steel during the continued forging process and fuse together with the bearing steel, causing the forged bearing steel to have raised or grooved parts, resulting in poor processing effect. Summary of the Invention

[0005] This invention provides a forging device and forging process for ball bearing steel, which solves the technical problem in related technologies that the edges of bearing steel will rapidly oxidize due to extrusion and high temperature, producing oxide scale.

[0014] As a further optimization of the present invention, the grinding rotating device provided on the two first rotating blocks at the center of one side of the first fixed block grinds the bearing steel, and the diameter of the third gear on the two first rotating blocks at the center of one side of the first fixed block is smaller than the diameter of the remaining third gear on one side of the first fixed block.

[0015] The second aspect of this invention discloses a forging process for ball bearing steel, comprising the following steps:

[0016] Step 1: Heat the bearing steel ingot to 900±5℃ and hold it for two hours. Then place the bearing steel on the processing support table for forging. Start the forging table and move it towards the processing support table to forge the bearing steel placed on the processing support table. The initial forging temperature is 900℃ and the final forging temperature is 800℃.

[0017] Step 2: After multiple forging operations on the forging press, a lot of oxide scale appears on the outer wall of the bearing steel. The first telescopic rod is activated to drive the first lifting block to rise, so that the third telescopic rod is in the center position of the bearing steel. Then, the third telescopic rod is activated to drive the clamping device and the grinding rotating device to move towards the bearing steel at the top of the processing support table. The first motor box is activated to drive the two first pulling blocks to move closer. Then, the multiple first pulling blocks move towards the center under the action of the first rotating block. The grinding rotating device set on the first rotating block clamps the bearing steel. The grinding rotating device is set with multiple first rings to adapt to the surface of the bearing steel and prevent the bearing steel from slipping when clamped.

[0018] Step 3: The motor drives the first transmission component to rotate, and the first transmission component drives the rotating component to rotate. The diameter of the third gear on the two first rotating blocks at the center of one side of the first fixed block is smaller than the diameter of the third gear on the other first rotating blocks at the center of one side of the first fixed block. Therefore, the smaller third gear has a faster rotation speed. The slower-rotating grinding device rotates the clamped bearing steel, while the faster-rotating grinding device polishes the oxide scale on the surface of the bearing steel, improving the processing quality of the bearing steel.

[0019] The beneficial effects of this invention are as follows:

[0020] The present invention discloses a ball bearing steel forging device and its forging process. Through the connection of multiple first rotating blocks and first pulling blocks inside the clamping device, rotating one of the first rotating blocks can drive the grinding rotating device to clamp the bearing steel. The grinding rotating device has a first adjusting component with a first ring. Multiple first rings adapt to the surface curvature of the bearing steel to prevent it from falling off during clamping. Third gears of different diameters drive the first rings to rotate at different speeds, thereby achieving the effect of cleaning and grinding the oxide scale on the outer wall of the bearing steel. This prevents the oxide scale on the bearing steel from being squeezed into the interior of the bearing steel during forging, which would cause the bearing steel surface to have protrusions and grooves.

[0034] 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.

[0035] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a ball bearing steel forging device, comprising a base 1, on which a first support column 11 is fixedly installed, and a top stabilizing block 12 is fixedly installed on the first support column 11. A forging table 17 is disposed inside the top stabilizing block 12. A second telescopic rod 15 and a processing support table 16 are disposed on the base 1. A first lifting block 13 is fixedly installed on the outer wall of the first support column 11. A first telescopic rod 14 and a third telescopic rod 131 are disposed on the first lifting block 13. A clamping device 2 is fixedly installed on the third telescopic rod 131.

[0036] like Figures 4 to 5 As shown, the clamping device 2 is equipped with a grinding and rotating device 3. The clamping device 2 clamps and grinds the bearing steel through the grinding and rotating device 3. The clamping device 2 includes a first fixing block 21, a first rotating block 22, and a first pulling block 23. The first rotating blocks 22 are symmetrically installed on the first fixing block 21, and multiple first rotating blocks 22 are connected in sequence. The bottom end of the first rotating block 22 is provided with a first pulling block 23. The first pulling blocks 23 at one end of the first fixing block 21 are connected in sequence. The two first rotating blocks 22 on the first fixing block 21 rotate to clamp the bearing steel. The grinding and rotating device 3 is provided on the first rotating block 22.

[0037] like Figures 6 to 8 As shown, the grinding rotating device 3 includes a first ring 35, a first telescopic member 36, a first adjusting member 37, and a second telescopic member 38. The first adjusting member 37 is disposed inside the first ring 35, and the first telescopic member 36 and the second telescopic member 38 are connected to the first adjusting member 37. The first ring 35 adapts to the surface curvature of the bearing steel through the first telescopic member 36 and the second telescopic member 38 to clamp and grind the bearing steel.

[0038] It should be noted that when the bearing steel is placed on the processing support table 16 for grinding, the forging table 17 is activated to forge the bearing steel. After forging, when a large amount of oxide scale appears on the outer wall of the bearing steel, the first telescopic rod 14 and the third telescopic rod 131 are activated to drive the clamping device 2 and the grinding rotating device 3 to clamp the bearing steel. Then, the motor drives the two first rotating blocks 22 on the first fixed block 21 to rotate, so that the multiple first rotating blocks 22 move closer to each other. The first rotating blocks 22 then drive the grinding rotating device 3 to move closer to each other, thereby clamping the bearing steel. The first rotating block 22 is equipped with multiple first rings 35, first telescopic components 36, first adjusting components 37, and second telescopic components 38 to adapt to the surface of the bearing steel and clamp the forged bearing steel. The first rotating block 22 is also equipped with a transmission device 4, which is connected to the grinding rotating device 3. The transmission device 4 is driven by a motor to drive the grinding rotating device 3 to rotate, which can improve the rotation and grinding effect of the bearing steel. This prevents the oxide scale on the outside of the bearing steel from being squeezed into the inside of the bearing steel during forging, causing the bearing steel surface to have protrusions and grooves, and improves the forging effect of the bearing steel.

[0039] like Figures 4 to 5As shown, the clamping device 2 includes a first fixing block 21 fixedly mounted on the third telescopic rod 131. A first rotating block 22 is symmetrically mounted on the first fixing block 21. The first rotating blocks 22 are rotatably mounted on the first fixing block 21. The first rotating blocks 22 on both sides of the first fixing block 21 are rotatably mounted in sequence. A first pulling block 23 is provided at the bottom end of the first rotating block 22. The first pulling block 23 is used to connect the two first rotating blocks 22. A first motor housing 26 is fixedly mounted at the bottom center of the first fixing block 21. A first screw 25 is threadedly mounted inside the first motor housing 26. A second rotating block 24 is symmetrically mounted on the first screw 25. The top end of the second rotating block 24 is rotatably mounted to the first pulling block 23. The first screw 25 is threadedly mounted to the second rotating block 24. The first screw 25 is rotated to adjust the distance between the two second rotating blocks 24.

[0040] It should be noted that the first fixed block 21 is provided with a first motor box 26, and the first motor box 26 is provided with a first screw 25. When the first motor box 26 rotates, it can drive the two first pulling blocks 23 to move closer to each other. Thus, the multiple first rotating blocks 22 drive the multiple first pulling blocks 23 to move, which can make the multiple second rotating blocks 24 move closer to each other, thereby achieving the clamping effect on the bearing steel.

[0041] like Figures 6 to 8 As shown, the grinding rotating device 3 includes L-shaped fixing blocks 31 on symmetrical first rotating blocks 22. The L-shaped fixing blocks 31 are fixedly installed on the first rotating blocks 22. First rotating columns 32 are rotatably installed on the two L-shaped fixing blocks 31. First telescopic members 36 are fixedly installed at the bottom of the first rotating columns 32. First adjusting members 37 are rotatably installed on the first telescopic members 36. First rings 35 are fixedly installed on the first adjusting members 37. Second telescopic members 38 are provided on the first adjusting members 37. Multiple first adjusting members 37 are connected through the second telescopic members 38. First belts 33 are provided on the first rotating columns 32. Rotating members 34 are provided on the first rotating blocks 22. Rotating members 34 are connected to the first rotating columns 32 through the first belts 33. Transmission devices 4 are provided on the rotating members 34. Transmission devices 4 are used to drive multiple grinding rotating devices 3 to rotate for rotating grinding of bearing steel.

[0042] It should be noted that the rotation of the rotating component 34 can drive the first belt 33 and the first rotating column 32 to rotate. The bottom of the first rotating column 32 is connected to the first telescopic component 36, the first adjusting component 37, and the second telescopic component 38, thereby driving the first ring 35 on the outer wall of the first adjusting component 37 to rotate. The rotation of the first ring 35 can drive the bearing steel to rotate and can also grind the bearing steel. The multiple first rings 35 can adapt to the surface of the bearing steel, preventing the bearing steel from slipping when clamped and improving safety.

[0043] like Figure 4 and Figure 6 as well as Figure 8 As shown, the rotating component 34 includes a third gear 343 rotatably mounted on the first rotating block 22, a fourth rotating column 342 fixedly mounted on the third gear 343, a third rotating column 341 disposed on the fourth rotating column 342, the third rotating column 341 being connected to the first rotating column 32 via the first belt 33, and a fifth gear 344 fixedly mounted on the outer wall of the fourth rotating column 342 connected to the first fixed block 21 on the first rotating block 22, and the fifth gear 344 being connected to the transmission device 4.

[0044] It should be noted that the fifth gear 344 rotates and the fourth rotating column 342 rotates. The fourth rotating column 342 is connected to the transmission device 4, thereby driving the multiple grinding rotating devices 3 on the multiple first rotating blocks 22 to rotate. The fourth rotating column 342 is equipped with a third rotating column 341 and a first belt 33, thereby driving the first rotating column 32 and the first ring 35 to rotate, so as to achieve the rotation and grinding effect on the bearing steel.

[0045] like Figure 7 As shown, the first telescopic member 36 includes a first U-shaped block 361 fixedly installed at the bottom of the first rotating column 32, a third rotating block 362 rotatably installed on the first U-shaped block 361, a fourth telescopic rod 363 fixedly installed on the third rotating block 362, a second U-shaped block 365 fixedly installed at the bottom of the fourth telescopic rod 363, the second U-shaped block 365 being connected to the first adjusting member 37, and a first spring 364 provided on the fourth telescopic rod 363.

[0046] It should be noted that when the multiple first rings 35 between the two first belts 33 are not concentric due to adapting to the curvature of the bearing steel surface, the fourth telescopic rod 363 is in the extended state, which allows the first rings 35 to move away from the first rotating block 22 and move closer to the first rotating block 22, thereby enabling the first rings 35 to adapt to the curvature of the bearing steel surface. The first spring 364 ensures that the fourth telescopic rod 363 keeps the first rings 35 at the top and bottom of the first rotating block 22 concentric in the normal state.

[0047] like Figure 7 As shown, the first adjusting member 37 includes a first rotating rod 373 rotatably mounted on the second U-shaped block 365. The first rotating rod 373 has a fifth fixing block 372 fixedly mounted at both ends. A cross-shaped fixing plate 371 is fixedly mounted on the fifth fixing block 372. The first rotating rod 373 is symmetrically mounted about the cross-shaped fixing plate 371. The first rotating rod 373 at the bottom is connected to the second telescopic member 38.

[0048] It should be noted that the first adjusting member 37 is a connector that connects the first telescopic member 36 and the second telescopic member 38. Therefore, the first adjusting member 37 can adapt to the first ring 35 moving in any direction, thereby improving the curvature of the bearing steel surface that the first ring 35 adapts to. Moreover, multiple first adjusting members 37 are interconnected through the second telescopic member 38. The function of the second telescopic member 38 is the same as that of the first telescopic member 36, which allows the first ring 35 to drive the first adjusting member 37 to adapt to the curvature of the bearing steel surface when clamping the bearing steel.

[0049] like Figure 7 As shown, the second telescopic member 38 includes a third U-shaped block 381 rotatably mounted on the first rotating rod 373, a fifth telescopic rod 382 fixedly mounted on the third U-shaped block 381, a fourth U-shaped block 384 fixedly mounted at the bottom of the fifth telescopic rod 382, ​​and a second spring 383 provided on the fifth telescopic rod 382.

[0050] It should be noted that the multiple first rings 35 in the middle of the first rotating block 22 are interconnected by the second telescopic member 38, so that when the first ring 35 clamps the bearing steel, it adapts to the curvature of the bearing steel surface, thereby preventing the first ring 35 from slipping when clamping the bearing steel and improving the clamping safety.

[0051] like Figure 4 and Figure 8As shown, the transmission device 4 includes a third fixed block 42 fixedly mounted on a first rotating block 22. A second rotating column 43 is rotatably mounted inside the third fixed block 42. A first gear 41 is fixedly mounted at one end of the second rotating column 43, and the first gear 41 meshes with the third gear 43. A universal joint 44 is fixedly mounted at the other end of the second rotating column 43. A sixth telescopic rod 45 is fixedly mounted on the universal joint 44. A fourth fixed block 46 is fixedly mounted on the adjacent first rotating block 22. The fourth fixed block 46 is rotatably mounted with the sixth telescopic rod 45. A second gear 47 is fixedly installed on the first rotating block 22. The second gear 47 meshes with the third gear 343 on the adjacent first rotating block 22. A transmission device 4 is provided on a plurality of first rotating blocks 22. A sixth gear 481 and a second motor 483 are provided on the first fixed block 21. The sixth gear 481 is symmetrically installed on the first fixed block 21. The second motor 483 is fixedly installed at the center of the first fixed block 21. A second belt 482 is provided on the outer wall of the sixth gear 481 and the second motor 483. The sixth gear 481 meshes with the fifth gear 344.

[0052] It should be noted that when the second motor 483 is started, the second belt 482 drives the sixth gear 481 to rotate. The sixth gear 481 meshes with the fifth gear 344, thereby driving multiple grinding rotating devices 3 to rotate. The rotation of the grinding rotating devices 3 can adjust the clamping position of the bearing steel when the first ring 35 clamps the bearing steel. At the same time, it can grind the bearing steel to prevent the oxide scale from being squeezed into the interior of the bearing steel during forging, causing problems such as protrusions and grooves. The transmission device 4 is equipped with a universal joint 44, which can adapt to the rotation angle of the first rotating block 22. The sixth telescopic rod 45 can adjust the distance between two adjacent first rotating blocks 22 to achieve the purpose of driving the grinding rotating devices 3 to rotate.

[0053] like Figure 4 As shown, the grinding rotating device 3 installed on the two first rotating blocks 22 at the center of one side of the first fixed block 21 grinds the bearing steel. The diameter of the third gear 343 on the two first rotating blocks 22 at the center of one side of the first fixed block 21 is smaller than the diameter of the remaining third gears 343 on one side of the first fixed block 21.

[0054] It should be noted that the grinding rotating devices 3 installed on the two first rotating blocks 22 at the center of one side of the first fixed block 21 grind the bearing steel. The diameter of the third gear 343 on the two first rotating blocks 22 at the center of one side of the first fixed block 21 is smaller than the diameter of the other third gears 343 on one side of the first fixed block 21. This allows the two grinding rotating devices 3 at the center of one side of the first fixed block 21 to rotate at a faster speed, which can grind the outer wall of the bearing steel, remove the oxide scale, and improve the processing accuracy of the bearing steel.

[0055] A forging process for ball bearing steel, the method employing the aforementioned forging apparatus for ball bearing steel, includes the following steps:

[0056] Step 1: Heat the bearing steel ingot to 900±5℃ and hold it for two hours. Then place the bearing steel on the processing support table 16 for forging. Start the forging table 17 and move the forging table 17 toward the processing support table 16 to forge the bearing steel placed on the processing support table 16. The initial forging temperature is 900℃ and the final forging temperature is 800℃.

[0057] Step 2: After multiple forging operations on the forging table 17, a lot of oxide scale appears on the outer wall of the bearing steel. The first telescopic rod 14 is activated to drive the first lifting block 13 to rise, so that the third telescopic rod 131 is in the center position of the bearing steel. Then, the third telescopic rod 131 is activated to drive the clamping device 2 and the grinding rotating device 3 to move towards the bearing steel at the top of the processing support table 16. The first motor box 26 is activated to drive the two first pulling blocks 23 to move closer. Then, the multiple first pulling blocks 23 move towards the center under the action of the first rotating block 22. The grinding rotating device 3 set on the first rotating block 22 clamps the bearing steel. The grinding rotating device 3 is equipped with multiple first rings 35 to adapt to the surface of the bearing steel and prevent the bearing steel from slipping when clamped.

[0058] Step 3: The motor drives the first transmission component 48 to rotate, and the first transmission component 48 drives the rotating component 34 to rotate. The diameter of the third gear 343 on the two first rotating blocks 22 at the center of one side of the first fixed block 21 is smaller than the diameter of the third gear 343 on the other first rotating blocks 22 at the center of one side of the first fixed block 21. Therefore, the smaller diameter third gear 343 rotates faster. The slower rotating grinding device 3 rotates the clamped bearing steel, and the faster rotating grinding device 3 polishes the oxide scale on the surface of the bearing steel, improving the processing quality of the bearing steel.

[0059] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.

8. A forging method for a ball bearing steel forging apparatus as described in claim 7, characterized in that: Includes the following steps: Step 1: Heat the bearing steel ingot to 900±5℃ and keep it warm for two hours. Then place the bearing steel on the processing support table (16) for forging. Start the forging table (17) and move the forging table (17) closer to the processing support table (16) to forge the bearing steel placed on the processing support table (16). The initial forging temperature is 900℃ and the final forging temperature is 800℃. Step 2: After multiple forging operations on the forging table (17), a lot of oxide scale appears on the outer wall of the bearing steel. The first telescopic rod (14) is activated to drive the first lifting block (13) to rise, so that the third telescopic rod (131) is in the center of the bearing steel. Then, the third telescopic rod (131) is activated to drive the clamping device (2) and the grinding rotating device (3) to move towards the bearing steel at the top of the processing support table (16). The first motor box (26) is activated to drive the two first pulling blocks (23) to move closer.

The diameter of the third gear (343) on the two first rotating blocks (22) at the center of one side of the first fixed block (21) is smaller than the diameter of the third gear (343) on the other first rotating blocks (22) at the center of one side of the first fixed block (21). Therefore, the smaller diameter of the third gear (343) rotates faster. The slower rotating grinding device (3) rotates the clamped bearing steel, while the faster rotating grinding device (3) polishes the oxide scale on the surface of the bearing steel, improving the processing quality of the bearing steel.
