Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically a forging device for bearing processing. Background Technology

[0002] Bearings are core components in mechanical equipment that support shaft-like parts and reduce friction and wear during operation. They reduce motion resistance through rolling or sliding contact while ensuring the rotational accuracy and stability of the shaft. During bearing manufacturing, applying pressure to the metal blank to induce plastic deformation significantly refines the metal grains, eliminates internal porosity and other defects, and improves the density, strength, and wear resistance of the bearing material. This, in turn, ensures the service life and reliable performance of the bearing under high-speed, heavy-load, and harsh operating conditions.

[0003] Existing technologies typically use forging hammers to repeatedly forge bearings. However, during the forging process, the bearings are prone to shifting. Therefore, fixed stops are often used to restrict the movement of the bearings. However, this method cannot adapt to bearing blanks of different diameters. When changing the blank specifications, repeated disassembly and adjustment are required, which is cumbersome and inefficient. Furthermore, the limiting points are mostly in local contact, resulting in uneven force on the blanks. Shifting is prone to occur during forging, leading to poor positioning accuracy and large deviations in the dimensions of the finished product. Utility Model Content

[0004] This utility model provides a forging device for bearing processing. It can drive the slide rod and slider to move synchronously radially along the slide groove through the arc groove on the annular toothed plate. With the help of the arc limiting plate and buffer spring in the limiting mechanism, it can achieve uniform ring-shaped limiting of bearing blanks of different diameters. At the same time, with the rotation of the placement table, it can ensure that the forging density of each part of the bearing blank is consistent, and reduce the problem of blank deformation or forging deviation.

[0005] To achieve the above objectives, a forging device for bearing processing is provided, comprising a worktable, a support frame fixedly connected to one end of the worktable, a hydraulic push rod fixedly connected to the upper end of the support frame, a forging hammer fixedly connected to the output end of the hydraulic push rod, a placement platform rotatably connected to the upper end of the worktable, a first motor fixedly connected inside the worktable, the output end of the first motor fixedly connected to the placement platform, and a limit mechanism provided around the placement platform.

[0006] According to the forging device for bearing processing, the upper surface of the worktable is provided with sliding grooves, which are distributed circumferentially and radially around the axis of the worktable. The sliding grooves are provided to facilitate the sliding of the slider, thereby driving the limiting mechanism to move synchronously closer to or further away from the blank, adapting to the processing requirements of bearings of different diameters.

[0007] According to the forging device for bearing processing, an annular toothed plate is rotatably connected inside the worktable. The surface of the annular toothed plate is provided with arc-shaped grooves, which are distributed circumferentially around the axis of the worktable. The annular toothed plate facilitates the rotation of the arc-shaped grooves on the surface, and the arc-shaped grooves facilitate the conversion of rotational motion into linear motion of the slider.

[0012] According to the forging device for bearing processing, a guide rod is fixedly connected to the outer surface of the limiting plate, and the guide rod is slidably connected to the arc-shaped plate and the slider. The guide rod is provided to conveniently limit the movement trajectory of the limiting plate, ensuring that the limiting plate can only extend and retract in the radial direction, preventing the limiting plate from shifting when the spring deforms, and ensuring the accuracy of the limiting position.

[0013] The beneficial effects of this utility model are as follows: the arc groove on the annular toothed plate drives the slide rod and slider to move radially synchronously along the slide groove. With the arc limiting plate and buffer spring in the limiting mechanism, it can achieve uniform ring-shaped limiting of bearing blanks of different diameters.

A support frame 2 is fixedly connected to one end of the worktable 1. A hydraulic push rod 3 is fixedly connected to the upper end of the support frame 2. A forging hammer 4 is fixedly connected to the output end of the hydraulic push rod 3. A buffer pad is installed at the connection point to offset the instantaneous impact force during forging and extend the service life of the component. A placement platform 5 is rotatably connected to the upper end of the worktable 1. A first motor 6 is fixedly connected inside the worktable 1. The output end of the first motor 6 is fixedly connected to the placement platform 5. A limit mechanism 7 is provided around the placement platform 5.

[0019] The upper surface of the worktable 1 is provided with a sliding groove 8, which is distributed circumferentially around the axis of the placement table 5 and is radial. The worktable 1 is rotatably connected to an annular toothed plate 9, and the surface of the annular toothed plate 9 is provided with an arc-shaped groove 10, which is distributed circumferentially around the axis of the placement table 5.

[0020] The slide groove 8 is slidably connected to the slider 11, and the lower end of the slider 11 is fixedly connected to the slide rod 12. The slide rod 12 is slidably connected to the arc groove 10. The slide rod 12 is made of hard alloy material and chrome-plated on the surface to enhance wear resistance. The worktable 1 is fixedly connected to the inside of the worktable 1. The output end of the second motor 13 is fixedly connected to the gear 14, and the gear 14 meshes with the ring toothed plate 9.

[0021] The limiting mechanism 7 includes an arc plate 701, a spring 702, and a limiting plate 703. The arc plate 701 is fixedly connected to one end of the slider 11. One end of the spring 702 is fixedly connected to the inside of the arc plate 701. The end of the spring 702 away from the arc plate 701 is fixedly connected to the limiting plate 703. The limiting plate 703 is arc-shaped. A guide rod 15 is fixedly connected to the outer surface of the limiting plate 703. The guide rod 15 is slidably connected to the inside of the arc plate 701 and the slider 11. Through holes are reserved inside the slider 11 and the arc plate 701 to facilitate the slidable connection of the guide rod 15.

[0022] Working principle: When forging bearing blanks of different diameters is required, the second motor 13 is started to drive the gear 14, which meshes with the annular toothed plate 9 to rotate the annular toothed plate 9. The arc groove 10 on the surface of the annular toothed plate 9 pushes the slide rod 12 to move, which in turn moves the slider 11 along the slide groove 8. The slider 11 synchronously drives the arc plate 701, spring 702 and limiting plate 703 to move. The limiting plate 703 contacts the outer surface of the bearing blank. Then, the first motor 6 and hydraulic push rod 3 are started synchronously. The first motor 6 drives the placement table 5 to rotate at a set uniform speed, which drives the bearing to rotate synchronously. The hydraulic push rod 3 drives the forging hammer 4 to move up and down reciprocatingly, pressing the bearing. Applying uniform forging pressure, during the forging process, the forging hammer 4 will generate an instantaneous impact force on the bearing and cause the bearing to vibrate slightly and shift. When the bearing shifts, it squeezes the limiting plate 703 and compresses the spring 702. The spring 702 generates elastic deformation and applies a reverse preload force, causing the limiting plate 703 to push the bearing back to its original position, indicating that its shift was excessive. Through the uniform rotation of the billet and the reciprocating forging of the forging hammer 4, all circumferential surfaces and parts of the bearing billet can be subjected to uniform pressure, achieving plastic deformation, effectively refining the metal grains, eliminating internal porosity defects, and ultimately improving the density, strength and wear resistance of the bearing material.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
