Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly machinery, in particular to an automatic shaping machine for curling bearing outer rings. Background Art

[0002] Stamping and shaping bearing outer rings is a technique used to improve or restore the shape accuracy of bearing outer rings during manufacturing or repair. This process is typically used to produce new bearings or repair bearing outer rings that have experienced minor deformation. Existing bearing outer rings often require crimping or flanging to improve the bearing's sealing properties, preventing dust, moisture, and other contaminants from entering the bearing interior, thereby extending the bearing's service life.

[0003] The curling or flanging process requires a specialized curling machine or press, using a suitable die to bend the edge of the bearing outer ring. Appropriate pressure is applied to gradually bend the outer ring edge to approximately 180°. This process can easily cause deformation of the outer ring, seriously affecting the sealing performance and assembly accuracy of the bearing after installation.

[0004] Existing automatic bearing outer ring shaping machines have complex structures, are difficult to install, and have high installation and equipment costs. For example, patent publication number CN214022730U provides an automatic bearing outer ring shaping machine that can automatically shape stamped outer ring bearings in batches. However, the lower die assembly in this patent is complex, and the shaping die is hot-pressed within the lower die as a single unit. This requires replacing the entire lower die for bearing outer rings of different sizes, which is inconvenient and costly.

[0005] In view of the above problems, it is necessary to provide an automatic shaping machine for rolled bearing outer rings with a simple structure, convenient operation and low cost to solve the above problems. Utility Model Content

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the scope of protection of the present invention.

[0032] (Example 1)

[0033] Due to sealing requirements, the existing bearing outer rings need to be curled. The curling process can easily cause deformation of the curled bearing outer rings. Therefore, this embodiment designs a convenient and efficient automatic curling bearing outer ring shaping machine that can replace curled bearing outer rings of different specifications.

[0034] See Figure 1 and Figure 2 , an automatic shaping machine for curled bearing outer ring, including a stamping mechanism 1, a shaping die 2 and a die base 3; the stamping mechanism 1 includes a punch base 1-1 fixed on the press and a punch 1-2 detachably fixed under the punch base 1-1.

[0035] The shaping mold 2 includes a die 2-2 and a core 2-3. A groove for accommodating the core 2-3 is provided in the center of the die 2-2, and a die inner hole 2-4 is provided in the center of the groove. The core 2-3 is detachably fixed in the groove in the center of the die 2-2, and a shaping inner hole 2-1 is provided in the center of the core 2-3; the shaping inner hole 2-1 and the die inner hole 2-4 are connected.

[0036] The mold base 3 comprises an upper mold base 3-3 and a lower mold base 3-4. The upper and lower mold bases 3-3 and 3-4 are fitted with a fixed portion that accommodates the shaping mold 2. The upper mold base 3-3 is secured to the lower mold base 3-4 via multiple screws, pressing the shaping mold 2 into the fixed portion. A feed channel 3-1 is located in the center of the upper mold base 3-3. Its diameter is larger than the diameter of the shaping inner hole 2-1. A discharge channel 3-2 is located in the center of the lower mold base 3-4. Its diameter is also larger than the diameter of the shaping inner hole 2-1.

[0037] The shaping die 2 is removably secured to the die base 3. The shaping inner hole 2-1 is connected to the feed channel 3-1 and the discharge channel 3-2, respectively. The punch 1-2 is positioned above the shaping inner hole 2-1 and is coaxially arranged with the shaping inner hole 2-1. In this embodiment, the punch presses downward, pressing the curled bearing outer ring into the shaping die. The outer ring is then shaped through the shaping inner hole and discharged through the discharge channel after shaping. The shaping die is also removably mounted on the die base, making it easy to replace the shaping die for bearing outer rings of different specifications.

[0038] Furthermore, the diameter of the punch 1-2 is smaller than the diameter of the shaping inner hole 2-1 and larger than the inner diameter of the rolled bearing outer ring 100. The diameter of the shaping inner hole 2-1 is smaller than the diameter of the die inner hole 2-4. This allows shaping of bearing outer rings of varying specifications by simply replacing the die core and punch, offering high adaptability and ease of operation.

[0039] Furthermore, a circular chamfer is provided above the shaped inner hole 2-1 at the center of the mold core 2-3. The circular chamfer serves as a guide, allowing the bearing outer ring to enter the shaped inner hole more smoothly, avoiding damage to the bearing outer ring due to misalignment, and improving the yield rate.

[0040] Furthermore, the punch 1-2 and the die core 2-3 are made of tungsten steel, which effectively improves the service life of the die.

[0041] In this embodiment, the rolled bearing outer ring is manually or conveyed to the shaping inner hole by a conveyor. A press drives the punch downward, forcing the rolled bearing outer ring into the shaping inner hole for shaping. The ring then falls into a collection device below the material discharge channel. This mechanism is easy to operate, effectively corrects deformation of the bearing outer ring caused by the hemming process, and significantly improves work efficiency compared to previous methods.

[0042] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
