Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing forging equipment technology, and in particular to an automatic forging device for bearing production. Background Technology
[0002] A bearing is a mechanical component whose main function is to support rotating mechanical parts, reduce the coefficient of friction during rotation, and ensure the rotational accuracy of the shaft, so that the rotating parts of the machine can operate smoothly and steadily. For example, bearings are needed in the wheels of a car, the crankshaft of an engine, and the rotors of various motors to achieve efficient rotational motion.
[0003] Existing automated forging equipment for bearing production uses positioning grooves on the lower die surface that match the shape of the raw material. This prevents the raw material from shifting during further processing and ensures that the billet can accurately withstand axial pressure during upsetting when the upper and lower dies are closed, allowing the metal fibers to flow in the expected direction and providing good positioning. However, this positioning groove design, which closely matches the shape of the raw material, makes the die highly specific. For example, a circular positioning groove designed for cylindrical billets cannot be used when upsetting other shapes such as square or irregular billets. This means that different dies need to be changed repeatedly for upsetting billets of different shapes. The increased variety and quantity of molds have raised production costs. Existing technology uses elastic materials, such as special rubber and elastic metal alloys, on the inner wall of the positioning groove. When the blank is placed in the positioning groove, the elastic material can automatically adjust the degree of fit according to the size of the blank to fix blanks of different sizes for processing. At the same time, the elastic material can also buffer and protect the blank, reducing collision damage during the placement process. However, after being subjected to pressure and temperature changes for a long time, the elastic material will experience aging and fatigue, which will reduce the elasticity of the material and make it unable to adapt well to changes in blank size to fix the bearing, thus affecting the final production quality of the bearing. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an automatic forging device for bearing production, which aims to improve the problem in the prior art that elastic materials will experience aging and fatigue after being subjected to long-term pressure and temperature changes, thus affecting the final production quality of bearings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic forging device for bearing production, comprising a machine body, electric push rods fixedly connected to the top left and right sides of the machine body, multiple square hollow blocks fixedly connected at equal intervals to the top of the machine body, a rack fixedly connected to the other end of the electric push rod, a bidirectional threaded rod rotatably connected to the rear side of the outer wall of the square hollow block, a gear fixedly connected to the rear end of the outer wall of the bidirectional threaded rod, the gear meshing with the rack, multiple movable plates threadedly connected at equal intervals to the outer wall of the bidirectional threaded rod, a threaded short column rotatably connected to the middle of the front movable plate, a semi-circular block slidably connected to the rear end of the threaded short column, and buffer mechanisms installed on the left and right sides of the outer wall of the machine body, the buffer mechanisms being used to buffer the transport of forged materials.
[0006] As a further description of the above technical solution:
[0007] The buffer mechanism includes an arc-shaped sliding plate, which is installed on the left and right sides of the outer wall of the machine body. Multiple H-shaped plates are fixedly connected at equal intervals to the bottom of the arc-shaped sliding plate.

Multiple hollow short blocks are fixedly connected at equal intervals to the inner wall of the arc-shaped sliding plate. Small springs are fixedly connected to the inner wall of the hollow short blocks. Large springs are fixedly connected to the top of the H-shaped plates. Sliding short blocks are slidably connected inside the hollow short blocks. The outer wall of the sliding short blocks is fixedly connected to the middle of the outer wall of the double-section rotating plates. A top plate is fixedly connected to the top of the upper H-shaped plates.
[0008] As a further description of the above technical solution:
[0009] A screw is threadedly connected to the front side of the outer wall of the machine body, and a hook is threadedly connected to the outer wall of the screw.
[0010] As a further description of the above technical solution:
[0011] The bottom of the machine body is fixedly connected with multiple support columns at equal intervals, and the bottom of each support column is fixedly connected with a foot pad.
[0012] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by activating the electric push rod, the front rack moves and meshes with the gear at the rear end of the bidirectional threaded rod, thereby causing the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is bidirectionally threaded, when it rotates, the two moving plates on the outer wall of the bidirectional threaded rod will move towards or away from each other along the bidirectional threaded rod. By rotating the threaded short column in the middle of the front moving plate, the semi-circular block at the rear end can be driven to adjust the position of the semi-circular block, so as to clamp and fix bearing forging materials of different sizes and shapes. This avoids the problem that the elastic material will age and fatigue after being subjected to pressure and temperature changes for a long time, which will affect the final production quality of the bearing.
[0022] 2. In this utility model, the large spring at the top of the H-shaped plate is compressed, and the large spring absorbs some energy through its own elastic deformation, thus reducing the impact force on the material. At the same time, the double-section rotating plates connected to the left and right sides of the H-shaped plate begin to rotate. Because the middle of the double-section rotating plates is fixedly connected to the sliding short block, when the double-section rotating plates rotate, they will squeeze the sliding short block, causing the sliding short block to slide inside the hollow short block and compress the small spring. The small spring further absorbs energy, enhancing the buffering effect, thereby avoiding the problem of reduced equipment efficiency caused by frequent manual handling and processing of materials.

[0030] 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.
[0031] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an automatic forging device for bearing production, comprising a body 1. Electric push rods 13 are fixedly connected to the left and right sides of the top of the body 1. Multiple square hollow blocks 6 are fixedly connected at equal intervals to the top of the body 1. A rack 3 is fixedly connected to the other end of each electric push rod 13. Activating the electric push rod 13 moves the rack 3 fixed at its front end. A bidirectional threaded rod 9 is rotatably connected to the rear side of the outer wall of each square hollow block 6. A gear 4 is fixedly connected to the rear end of the outer wall of the bidirectional threaded rod 9, meshing with the rack 3. Multiple movable plates 20 are threadedly connected at equal intervals to the outer wall of the bidirectional threaded rod 9, serving as movable clamps. The front movable plate 20 is rotatably connected to a threaded short column 21 in the middle. The rear end of the threaded short column 21 is slidably connected to a semi-circular block 19, which serves to rotate and clamp. The outer walls of the machine body 1 are equipped with buffer mechanisms 2 on both the left and right sides. The buffer mechanisms 2 are used to buffer the transport of forged materials. The front side of the outer wall of the machine body 1 is threaded with a screw 12. The outer wall of the screw 12 is threaded with a hook 11, which can be used to hang tools for daily use and cleaning. The bottom of the machine body 1 is fixedly connected with multiple support columns 22 at equal intervals. The bottom of the support columns 22 is fixedly connected with foot pads 10, which can reduce the vibration of the equipment during operation.
[0032] Specifically, by activating the electric push rod 13, the front rack 3 is moved. When the rack 3 moves, it meshes with the square hollow block 6 and the gear 4 at the rear end of the bidirectional threaded rod 9, thereby causing the bidirectional threaded rod 9 to rotate. Since the bidirectional threaded rod 9 is bidirectional threaded, when it rotates, the two moving plates 20 on the outer wall of the bidirectional threaded rod 9 will move towards or away from each other along the bidirectional threaded rod 9. By rotating the threaded short column 21 in the middle of the front moving plate 20, the semi-circular block 19 at the rear end can be driven to adjust the position of the semi-circular block 19, so as to clamp and fix bearing forging materials of different sizes and shapes, and provide stable processing conditions for the forging process. The front of the outer wall of the machine body 1 is threaded with a screw 12, and the outer wall of the screw 12 is threaded with a hook 11. The hook 11 can be used to hang tools for daily use and cleaning. Multiple support columns 22 are fixedly connected at equal intervals at the bottom of the machine body 1. The bottom of the support columns 22 is fixedly connected with a foot pad 10, which can reduce the vibration of the equipment during operation.
[0033] Reference Figure 1 , Figure 4 and Figure 5 The buffer mechanism 2 includes an arc-shaped sliding plate 201, which is installed on the left and right sides of the outer wall of the body 1. Multiple H-shaped plates 204 are fixedly connected at equal intervals to the bottom of the arc-shaped sliding plate 201. Double-section rotating plates 202 are rotatably connected to the left and right sides of the outer wall of each H-shaped plate 204, serving a rotational function. Multiple hollow short blocks 205 are fixedly connected at equal intervals to the inner wall of the arc-shaped sliding plate 201. Small springs 206 are fixedly connected to the inner wall of each hollow short block 205, serving a secondary buffering and force-dissipating function. A large spring 203 is fixedly connected to the top of each H-shaped plate 204. Sliding short blocks 207 are slidably connected inside each hollow short block 205. The wall is fixedly connected to the middle of the outer wall of the double-section rotating plate 202. The rotation of the double-section rotating plate 202 can push the sliding short block 207 to compress the small spring 206 for buffering and force release. The top plate 208 is fixedly connected to the top of the upper H-shaped plate 204. A circular handle 8 is fixedly connected to the front end of the outer wall of the threaded short column 21. The circular handle 8 can facilitate the rotation of the threaded short column 21. A protective sleeve 5 is fixedly connected to the outer wall of the circular handle 8. A screw 18 is threadedly connected to the middle of the outer wall of the rear moving plate 20. An anti-slip pad 7 is threadedly connected to the outer wall of the screw 18. The anti-slip pad 7 on the outer wall of the rear moving plate 20 can enhance the moving plate 20 to prevent slippage when clamping forging materials.
[0034] Specifically, the impact force generated by the material sliding down first acts on the curved sliding plate 201, and the bottom H-shaped plate 204 will feel the pressure. At this time, the large spring 203 at the top of the H-shaped plate 204 is compressed. The large spring 203 absorbs some energy through its own elastic deformation, reducing the impact force of the material. At the same time, the double-section rotating plate 202 connected to the left and right sides of the H-shaped plate 204 begins to rotate. Because the middle of the double-section rotating plate 202 is fixedly connected to the sliding short block 207, when the double-section rotating plate 202 rotates, it will squeeze the sliding short block 207, causing the sliding short block 207 to... 07 Slides and compresses the small spring 206 inside the hollow short block 205. The small spring 206 further absorbs energy and enhances the buffering effect. A circular handle 8 is fixedly connected to the front end of the outer wall of the threaded short column 21. The circular handle 8 can facilitate the rotation of the threaded short column 21. A protective sleeve 5 is fixedly connected to the outer wall of the circular handle 8. A screw 18 is threadedly connected to the middle of the outer wall of the rear moving plate 20. An anti-slip pad 7 is threadedly connected to the outer wall of the screw 18. The anti-slip pad 7 on the outer wall of the rear moving plate 20 can enhance the movement plate 20 to prevent slippage when clamping the forging material.
[0035] Reference Figure 1 and Figure 2 A hollow box 17 is fixedly connected to the bottom of the body 1. A drawer 16 is slidably connected inside the hollow box 17. The drawer 16 can conveniently store tools for daily use and maintenance for later use. A handle 14 is fixedly connected to the front side of the outer wall of the drawer 16. A protective cover 15 is fixedly connected to the outer wall of the handle 14. The handle 14 fixedly connected to the front side of the outer wall of the drawer 16 can facilitate opening and closing the drawer 16 for use.
[0036] Specifically, a hollow box 17 is fixedly connected to the bottom of the body 1, and a drawer 16 is slidably connected inside the hollow box 17. The drawer 16 can conveniently store tools for daily use and maintenance for later use. A handle 14 is fixedly connected to the front side of the outer wall of the drawer 16, and a protective cover 15 is fixedly connected to the outer wall of the handle 14. The handle 14 fixedly connected to the front side of the outer wall of the drawer 16 can facilitate opening and closing the drawer 16 for use.
[0037] Working principle: By activating the electric push rod 13, the front rack 3 is moved. When the rack 3 moves, it meshes with the square hollow block 6 and the gear 4 at the rear end of the double-threaded rod 9, thereby rotating the double-threaded rod 9. Since the double-threaded rod 9 is double-threaded, when it rotates, the two moving plates 20 on the outer wall of the double-threaded rod 9 will move towards or away from each other along the double-threaded rod 9. By rotating the threaded short column 21 in the middle of the front moving plate 20, the semi-circular block 19 at the rear end can be driven to adjust the position of the semi-circular block 19, so as to clamp and fix bearing forging materials of different sizes and shapes, providing stable processing conditions for the forging process. This avoids the problem that the elastic material will age and fatigue after being subjected to pressure and temperature changes for a long time, which will affect the final production quality of the bearing.
[0038] The impact force generated by the material sliding down first acts on the curved slide plate 201, and the H-shaped plate 204 at the bottom will feel the pressure. At this time, the large spring 203 at the top of the H-shaped plate 204 is compressed. The large spring 203 absorbs some energy through its own elastic deformation, thus reducing the impact force of the material. At the same time, the double-section rotating plate 202 connected to the left and right sides of the H-shaped plate 204 begins to rotate. Because the middle of the double-section rotating plate 202 is fixedly connected to the sliding short block 207, when the double-section rotating plate 202 rotates, it will squeeze the sliding short block 207, causing the sliding short block 207 to slide in the hollow short block 205 and compress the small spring 206. The small spring 206 further absorbs energy and enhances the buffering effect, thereby avoiding the problem of reduced equipment efficiency caused by frequent manual handling and processing of materials.
