Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 8 The present invention provides a technical solution: a stamping device for bearing processing, comprising a support seat 1 and a stamping seat 11, a first rotating seat 2 is installed inside the top of the stamping seat 11 through a hydraulic cylinder, a first fixed seat 3 is installed on the inner wall of the first rotating seat 2, a punch column 9 is installed on the outer wall of the support seat 1, and a second fixed seat 7 is installed on the outer side of the top of the punch column 9, a second rotating seat 6 is installed on the outer wall of the second fixed seat 7, and an adjustment component 4 is installed in the second fixed seat 7 and the first fixed seat 3, and a moving groove 21 is opened on the inner wall of the second rotating seat 6 and the first rotating seat 2, and a tooth groove 22 is opened on the inner wall of the moving groove 21, the first rotating seat 2 is connected to the second rotating seat 6 through a positioning component 5, a rotating stamping component 8 is installed on the outer wall of the punch column 9, and the first rotating seat 2 is connected to the second rotating seat 6 through the positioning component 5, forming a linked whole, which can quickly adjust the size of the stamping die set, ensure the accuracy of the relative position of the upper and lower dies during the adjustment process, avoid the stamping quality problems caused by position deviation, and improve work efficiency;

[0031] The adjusting component 4 includes an extrusion block 401 slidably mounted on the inner walls of the first fixed seat 3 and the second fixed seat 7, and a moving rod 402 is installed on the outer wall of the extrusion block 401, and a rotating column 403 is rotatably installed at the end of the moving rod 402 away from the extrusion block 401, and a rotating gear 404 is installed at both ends of the rotating column 403, and also includes a pulling bar 405 installed on the outer side of the extrusion block 401, and a pulling groove 406 is opened on the inner wall of the pulling bar 405. Through the mutual engagement of the rotating gear 404 and the teeth of the inner wall of the pulling groove 406, when the rotating gear 404 rotates with the rotating column 403, the pulling bar 405 can be driven to pull the extrusion block 401 from both sides to adjust the curvature of the extrusion block 401, so that the extrusion block 401 can better adapt to the curvature requirements of bearing seats of different sizes and specifications, thereby increasing the scope of application of the device, improving the versatility of the stamping die set, eliminating the need for frequent mold replacement, and saving production time and cost.

[0032] As an embodiment of the present invention, the end of the rotating column 403 is located in the tooth groove 22, and the cross-section of the tooth groove 22 is designed to be a gradually opened circular arc. The rotating gear 404 is meshed with the teeth on the inner wall of the tooth groove 22. The tooth groove 22 provides a smooth moving space for the rotating column 403, improves the accuracy of the upper mold adjustment, and ensures the high efficiency and stability of power transmission. The rotating gear 404 is meshed with the teeth on the inner wall of the tooth groove 22, so that the extrusion block 401 group can adapt to the processing of bearings of various different specifications, without the need for frequent replacement of the stamping die set, thereby improving the versatility of the device and reducing production costs.

[0033] As an embodiment of the present invention, four extrusion blocks 401 are installed on the inner wall of the first fixed seat 3. The extrusion blocks 401 are designed with an arc-shaped structure. Multiple groups of extrusion blocks 401 can apply pressure to the bearing blank from multiple directions at the same time, avoiding product deformation or quality defects caused by uneven force, and can better adapt to the circular characteristics of the bearing. The four groups of extrusion blocks 401 can provide more flexibility for the device. By adjusting the position parameters of the extrusion blocks 401, the size of the stamping die can be adjusted, thereby expanding the range of action of the stamping die.

[0034] As an embodiment of the present invention, two pulling strips 405 are symmetrically installed on both sides of the outer wall of each extrusion block 401, and the rotating gear 404 is meshed with the teeth on the inner wall of the pulling groove 406. The symmetrically installed pulling strips 405 ensure the balanced force applied to the extrusion block 401, avoiding deformation of the extrusion block 401 due to uneven force, thereby ensuring the stability of the upper mold structure. The rotating gear 404 is meshed with the teeth on the inner wall of the pulling groove 406. When the rotating gear 404 rotates due to the movement of the rotating column 403, the rotating gear 404 can accurately drive the pulling strip 405 to move and adjust the curvature of the extrusion block 401.

[0035] As an embodiment of the present invention, after the rotating gear 404 rotates, the moving directions of the two groups of pulling bars 405 are perpendicular to each other. When the rotating gear 404 rotates, the two groups of pulling bars 405 move perpendicular to each other, so that the pulling bars 405 can exert force on the extrusion block 401 from different angles, and work together to achieve flexible adjustment of the curvature of the extrusion block 401, so that it can better fit the curvature of bearing seats of different specifications, complete the adaptation to different sizes, improve the adaptability and processing accuracy of the product, help maintain the stability of the stamping die structure, reduce the wear and damage of the stamping die, extend the service life of the stamping die, and also ensure the consistency and stability of the quality of the stamping products.

[0036] As an embodiment of the present invention, the positioning assembly 5 includes a first sliding groove 502 opened on the inner wall of the first rotating seat 2, and also includes a second sliding groove 503 opened on the inner wall of the second rotating seat 6. An elastic telescopic rod 501 is connected between the first sliding groove 502 and the second sliding groove 503. The elastic telescopic rod 501 enables the first rotating seat 2 and the second rotating seat 6 to operate in coordination, ensuring the consistency and stability of the entire stamping die during the size adjustment process, and the elastic telescopic rod 501 can adaptively adjust its own telescopic degree and position under the guidance of the first sliding groove 502 and the second sliding groove 503, thereby ensuring that the positioning function of the material to be processed is always effective and reducing product rework and scrapping due to inaccurate positioning.

[0037] As an embodiment of the present invention, three groups of first sliding grooves 502 are opened at equal angles on the inner wall of the first rotating seat 2, and the positions of the first sliding grooves 502 and the second sliding grooves 503 correspond to each other, and the inner walls of the first sliding grooves 502 and the second sliding grooves 503 are designed to be inclined in opposite directions. The three groups of first sliding grooves 502 are distributed at equal angles, and cooperate with the second sliding grooves 503 at corresponding positions, which is conducive to realizing multi-angle and all-round positioning of the material to be processed, and effectively preventing the material from being displaced by translation, rotation and the like during the stamping process, reducing the defective rate, ensuring processing accuracy, and ensuring product quality. The inclined design of the first sliding grooves 502 and the second sliding grooves 503 provides guidance for the movement of the elastic telescopic rod 501, ensuring stable power transmission, enabling the device to operate stably, and improving the reliability of adjustment and positioning.

[0038] As an embodiment of the present invention, the ends of the elastic telescopic rod 501 slide in the first sliding groove 502 and the second sliding groove 503 respectively, and when the outer wall of the first rotating seat 2 is in contact with the outer wall of the second rotating seat 6, the elastic telescopic rod 501 is completely retracted and enters the inner wall of the first sliding groove 502 and the second sliding groove 503. The embedded design ensures that the elastic telescopic rod 501 can operate stably in the sliding groove. The three groups of elastic telescopic rods 501 will perform smooth extension or contraction movements according to the guidance of the first sliding groove 502 and the second sliding groove 503 inclined to the axis, thereby achieving precise positioning of the material to be processed. After positioning is completed, the elastic telescopic rod 501 will be completely retracted into the first sliding groove 502 and the second sliding groove 503, and will be effectively protected. It will not affect the subsequent stamping work, and at the same time, the elastic telescopic rod 501 itself is protected from damage, thereby improving the smoothness and continuity of the operation of the device.

[0039] As an embodiment of the present invention, the rotating stamping assembly 8 includes a rotating plate 805 installed on the top of the support seat 1 through a spring 806, and a moving seat 801 is rotatably installed on the outer wall of the rotating plate 805, and a moving protrusion 802 is installed on the outer wall of the moving seat 801, and also includes an extrusion seat 803 installed on the outer wall of the support seat 1, and the inner wall of the extrusion seat 803 is provided with a rotating groove 804 for the moving protrusion 802 to slide, and the rotating groove 804 is distributed in a spiral structure. When the stamping seat 11 is pressed down to work, the moving seat 801 moves downward under the extrusion force, and the moving protrusion 802 installed on the outer wall will slide in the rotating groove 804. Due to the special shape design of the rotating groove 804, the moving protrusion 802 will drive the moving seat 801 to rotate while sliding, and the stamping position will be adjusted in real time to ensure that the stamping die and the material to be processed always maintain good contact and pressure distribution during the stamping process, reduce the product size deviation and surface defects caused by the gap after the extrusion block 401 moves to adjust the mold size, and improve the product yield.

[0040] Working principle: When using the stamping device for bearing processing, first rotate the first rotating seat 2. Since the tooth groove 22 is designed to be an involute arc, the rotating column 403 installed on the inner wall of the tooth groove 22 will drive the extrusion block 401 to move linearly through the moving rod 402 as the first rotating seat 2 rotates, and the relative positions of the multiple groups of extrusion blocks 401 are adjusted. The tooth groove 22 provides a smooth and fluent motion track for the rotating column 403, ensuring that its movement process is smooth and free of jams, thereby improving the accuracy of the position adjustment of the extrusion block 401. As the rotating column 403 moves, the rotating gear 404 installed at its end will It will mesh with the teeth on the inner wall of the tooth groove 22, driving the rotating gear 404 to rotate. Since the rotating gear 404 meshes with the teeth on the inner wall of the pulling groove 406, the rotating gear 404 will synchronously drive the pulling bar 405 to move when it rotates, so that the two groups of pulling bars 405 move in directions perpendicular to each other, and pull the extrusion block 401 from both sides, so as to adjust the curvature of the extrusion block 401, so that the extrusion block 401 group can adapt to the curvature requirements of bearing seats of different specifications, so as to meet the production requirements of bearing seats of different sizes and specifications, thereby improving the production efficiency and versatility of the device and reducing the production cost;

[0041] When the first rotating seat 2 rotates, one end of the elastic telescopic rod 501 is firmly connected to the first rotating seat 2, and the other end is closely connected to the second rotating seat 6. When the first rotating seat 2 rotates, under the action of the elastic telescopic rod 501, the second rotating seat 6 will be smoothly driven to rotate synchronously. After the second rotating seat 6 rotates, it further drives the adjustment component 4 installed on the inner wall of the second fixed seat 7, so that the adjustment component 4 installed on the inner wall of the second fixed seat 7 can synchronously adjust the position of the extrusion block 401. Through the coordinated adjustment of the first rotating seat 2 and the second rotating seat 6, the size adjustment of the stamping die set can be quickly realized, so that when producing bearing seats of different sizes and specifications, the staff only needs to replace the punch column 9 separately, which reduces the disassembly and assembly steps and improves the work efficiency.

[0042] When the size of the stamping die set is adjusted, the stamping device is started to drive the stamping seat 11 to press down to perform the stamping work. At the same time as the stamping seat 11 is pressed down, since the first sliding groove 502 and the second sliding groove 503 are designed to be inclined toward the axis, the elastic telescopic rod 501 will be guided by this inclined structure, as if sliding smoothly and accurately toward the axis direction. Through the mutual cooperation of the three groups of elastic telescopic rods 501, the material to be processed placed on the workbench is positioned from multiple directions. Through this comprehensive and accurate positioning method, the defective rate caused by material displacement is effectively reduced, and the product quality is effectively guaranteed. When the outer wall of the first rotating seat 2 is in contact with the outer wall of the second rotating seat 6, the elastic telescopic rod 501 is completely retracted and enters the first sliding groove 502 and the second The inner wall of the sliding groove 503 does not affect the subsequent stamping work, while protecting the elastic telescopic rod 501 itself from damage, ensuring the smooth progress of the stamping process. As the stamping seat 11 continues to press down, the moving seat 801 begins to move downward due to the extrusion force. During the movement of the moving seat 801, the moving protrusion 802 installed on its outer wall not only moves downward synchronously, but also moves along the rotating groove 804 distributed in a spiral structure under the extrusion action of the rotating groove 804, thereby driving the moving seat 801 to rotate, making the stamping process more flexible, so as to offset the influence of the gap inside the mold after the extrusion block 401 moves, so that it can better adapt to the stamping processing of bearing seats with different specifications and different process requirements, thereby improving the versatility of the equipment.
