[0002] In the field of mechanical processing, especially in ring rolling, small core rollers are an important tool. Their performance and structure directly affect processing efficiency and product quality. Traditional small core roller designs often have several technical deficiencies, which limit their application effectiveness and service life in complex working conditions.

[0003] First, the connection between the outer shell and the shaft of traditional small core rollers is relatively simple, often lacking effective support and positioning mechanisms. This results in the shaft being prone to deflection and loosening under long-term operation and high loads, which in turn affects machining accuracy and ring quality. Furthermore, the lack of fastening and anti-loosening mechanisms makes the equipment prone to failure in high-vibration working environments.

[0004] Secondly, the housings of traditional small core rollers are not well sealed, often lacking effective end caps and gaskets. This allows external impurities such as dust and metal shavings to easily enter the housing, accelerating wear on the bearings and shafts and shortening the equipment's lifespan. Furthermore, the lack of effective heat dissipation within the housing causes the equipment to heat up after extended operation, affecting bearing and shaft performance and even causing failures.

[0005] In summary, the traditional small core roller has many deficiencies in structural design and selection, and it is difficult to meet the requirements of high precision, high efficiency and high stability in the field of modern mechanical processing. Utility Model Content

[0022] Example:

[0023] like Figure 1-Figure 2 As shown, the utility model provides a universal small core roller for ring rolling.

[0024] It includes a shell 1, a rotating shaft 2, a bearing 3, and a connecting piece. A through hole is provided at one end of the shell 1. One end of the rotating shaft 2 extends into the shell 1 through the through hole. The bearing 3 is provided at the intersection of the rotating shaft 2 and the shell 1. The rotating shaft 2 extends into the shell 1 through the bearing 3. The connecting piece is provided on the rotating shaft 2 located outside the shell 1.

[0025] The bearing 3 is provided with a fastening mechanism, which includes a fastening nut 4 and a locking washer. The fastening nut 4 is screwed to the outer side of the bearing 3, and the locking washer is located between the fastening nut 4 and the bearing 3 to enhance the stability of the connection and prevent loosening.

[0026] A closed end cover 5 is provided at the other end of the housing 1 , and the closed end cover 5 is connected to the housing 1 by bolts, and a sealing gasket is provided between the contact surface of the closed end cover 5 and the housing 1 to prevent external impurities from entering the interior of the housing 1 .

[0027] The connecting piece is a flange structure, the center of which is coaxially fixedly connected to the rotating shaft 2, and the outer edge of the flange is evenly distributed with multiple mounting holes, which facilitates quick connection with external equipment through bolts or other fasteners.

[0028] The surface of the rotating shaft 2 located inside the housing 1 is provided with a wear-resistant coating.

[0029] The outer surface of the housing 1 is provided with heat dissipation fins, which are evenly distributed and perpendicular to the axis of the housing 1 , thereby increasing the heat dissipation area of ​​the housing 1 .

[0030] A guide groove is provided on the inner wall of the through hole, and a guide key matching the guide groove is provided at a corresponding position of the rotating shaft 2 to ensure that the rotating shaft 2 can stably maintain a predetermined position during rotation to avoid deflection.

[0031] By arranging a bearing 3 at the junction of the housing 1 and the rotating shaft 2, and arranging a fastening mechanism including a fastening nut 4 and a locking washer on the bearing 3, it is ensured that the rotating shaft 2 can be stably maintained in the predetermined position during rotation to avoid deflection and loosening. The guide groove arranged on the inner wall of the through hole cooperates with the guide key on the rotating shaft 2, further enhancing the positioning accuracy and stability of the rotating shaft 2.

[0032] A closed end cover 5 is provided at the other end of the housing 1 and is tightly fixed to the housing 1 by bolt connection. A sealing gasket is provided between the contact surface of the closed end cover 5 and the housing 1 to effectively prevent external impurities from entering the interior of the housing 1 and protect the bearing 3 and the rotating shaft 2 from contamination.

[0033] The heat dissipation fins arranged on the outer surface of the shell 1 increase the heat dissipation area, which helps to reduce the temperature of the equipment during operation and maintain the stable performance of the bearing 3 and the shaft 2. The part of the surface of the shaft 2 located inside the shell 1 is provided with a wear-resistant coating, which improves the wear resistance of the shaft 2 and extends the service life of the equipment.

[0034] The connecting piece adopts a flange structure, the center of which is coaxially fixed with the rotating shaft 2. The outer edge of the flange is evenly distributed with multiple mounting holes, which facilitates quick connection with external equipment through bolts or other fasteners, thereby improving the installation efficiency and versatility of the equipment.

[0035] During use of the present application, the outer shell 1 of the small core roller is first fixed to the corresponding position of the ring rolling machine by bolts, and the flange connector is quickly connected to external equipment such as a drive device or a ring rolling mold using bolts or other fasteners.

[0036] Start the ring rolling machine, and the driving device drives the rotating shaft 2 to rotate through the flange connector. The rotating shaft 2 rotates stably under the support of the bearing 3. At the same time, the cooperation between the guide groove and the guide key ensures that the rotating shaft 2 remains in the predetermined position.

[0037] During the rotation of the shaft 2 , the ring to be processed is placed in the ring rolling die. The shaft 2 rolls the ring through friction or mechanical force, gradually shaping it.

[0038] During the processing, the heat dissipation fins dissipate the heat generated by the equipment into the air, keeping the equipment temperature stable. The closed end cover 5 and the sealing gasket effectively prevent external impurities from entering the interior of the housing 1, protecting the bearing 3 and the rotating shaft 2 from contamination and wear. After the processing is completed, the ring rolling machine is stopped and the connection between the external equipment and the flange connector is disconnected.

[0039] The present application ensures the stability and positioning accuracy of the rotating shaft 2 during rotation by arranging a bearing 3 at the junction of the housing 1 and the rotating shaft 2, and adopting a fastening mechanism including a fastening nut 4 and a locking washer on the bearing 3. The cooperation between the guide groove and the guide key further enhances the stability of the rotating shaft 2, prevents deflection and shaking, and thus improves the processing accuracy.

[0040] The present application effectively reduces the friction and wear between the rotating shaft 2 and the ring or other components by setting a wear-resistant coating on the surface of the rotating shaft 2, maintains the flatness and processing accuracy of the surface of the rotating shaft 2, and extends the service life of the equipment.

[0041] The connecting piece of this application adopts a flange structure, and the mounting hole design on it enables the small core roller to be easily connected to a variety of external equipment, enhancing the versatility and adaptability of the equipment. This design simplifies the installation process, improves installation efficiency, and facilitates subsequent maintenance and replacement.

[0042] The closed end cover 5 and the sealing gasket provided at the other end of the housing 1 effectively prevent external dust, metal chips and other impurities from entering the interior of the housing 1, protecting the bearing 3 and the rotating shaft 2 from pollution and wear, and improving the reliability and durability of the equipment.

[0043] The heat dissipation fins provided on the outer surface of the housing 1 increase the heat dissipation area, improve the heat dissipation efficiency of the device, help to maintain a stable temperature of the device during operation, and protect internal components from high temperature.

[0044] Wear-resistant coatings, fastening mechanisms, sealing gaskets and other designs work together to reduce equipment wear and failure rates, and lower maintenance costs caused by replacing parts.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
