[0016] 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.
[0017] Please see Figure 1-3This utility model provides a technical solution: a valve head forming stamping device, including a stamping base 1, a bottom mold base 2 installed in the middle of the top of the stamping base 1, a plurality of bottom molds installed on the top of the bottom mold base 2, a lifting frame 3 driven by guide rails on both sides of the stamping base 1, a base 4 fixedly installed in the middle of the lifting frame 3 by bolts, a rotation switching mechanism consisting of a fixed circular plate 6 and a moving circular plate 7 connected to the bottom of the base 4 by a coupling 5, and four vertically distributed guide rail frames 8 surrounding the bottom of the moving circular plate 7, with stamping heads 9 driven by guide rails on the inner side of the guide rail frames 8, the four stamping heads 9 being of different models, and a stamping buffer mechanism consisting of a pressure cylinder 10, a pressure spring 11 and a pressure rod 12 being provided on both sides of the moving circular plate 7. This structure is suitable for valve head forming. During operation, the stamping base 1 provides a stable foundation support, while the bottom mold base 2 provides precise positioning for the valve to be formed. The lifting frame 3 on both sides is driven by guide rails, allowing the base 4 to be adjusted in height as needed, ensuring the accuracy of the stamping process. The rotary switching mechanism composed of the fixed circular plate 6 and the moving circular plate 7 allows the moving circular plate 7 to rotate rapidly to select one of the four stamping heads 9 suitable for different valve models, significantly reducing changeover time and improving production efficiency. Furthermore, each stamping head 9 is driven by the guide rails on the inner side of the guide rail frame 8, achieving high-precision stamping action and ensuring the consistency and accuracy of the forming quality. At the same time, the stamping buffer mechanism composed of the pressure cylinder 10, the pressure spring 11, and the pressure rod 12 absorbs and mitigates the impact force during each stamping process, effectively protecting the equipment from high-intensity shocks. This reduces the damage caused by material stamping, lowers the wear rate, extends the service life of the mold, and improves the product forming accuracy. This solves the problems of easy equipment damage, low product forming accuracy, and long replacement time for stamping heads caused by the lack of an effective buffering mechanism in existing technologies. Therefore, it significantly improves production efficiency and equipment durability, meeting the requirements of modern production lines for high efficiency, precision, and stability. The pressure rod 12 is symmetrically and vertically inserted through both sides of the moving circular plate 7. The pressure cylinder 10 is movably sleeved on the bottom end of the pressure rod 12, and the compression spring 11 is sleeved on the top of the connection between the pressure rod 12 and the pressure cylinder 10. In this structure, when the lifting frame 3 drives the entire stamping mechanism to rise and fall synchronously, the pressure cylinder 10 will first contact the table surface of the stamping seat 1. As the pressure increases, the pressure cylinder 10 begins to move upward along the pressure rod 12. This causes the compression spring 11 to be compressed. When compressed, the compression spring 11 can effectively absorb and buffer the impact force brought by the high-strength material stamping, reducing the stress directly acting on the equipment and protecting key components from damage. This linkage mechanism not only improves the safety and stability of operation, but also significantly reduces equipment wear through effective buffering, extends service life, and improves the consistency and precision of product molding. The outer end of the pressure rod 12 is also fitted with a control ring 13. A receiving block 1301 is welded and fixed to the outside of the control ring 13. Adjusting bolts 14 are also inserted through the threaded structure on both sides of the moving circular plate 7. The bottom end of the adjusting bolt 14 is welded and fixed with a lower pressure block 1401. The top of the receiving block 1301 is provided with a notch that matches the structure of the lower pressure block 1401.When the compression degree of the compression spring 11 needs to be adjusted to control the buffering force, this structure can be achieved by rotating the adjusting bolt 14. Rotating the adjusting bolt 14 moves the lower pressure block 1401 downwards and into contact with the notch at the top of the receiving block 1301. As the adjusting bolt 14 is further tightened, the lower pressure block 1401 applies pressure to the receiving block 1301, thereby pushing the control ring 13 downwards along the pressure rod 12, compressing the compression spring 11 to the desired degree. This allows for precise adjustment of the preload of the compression spring 11, thereby controlling the effectiveness of the buffering mechanism and ensuring optimal buffering protection during the stamping of materials of different strengths and types. (Fixed round plate 6) The fixed circular plate 6 and the moving circular plate 7 are connected at their center by a bearing, and a drive motor is fixedly installed at the center of the top of the fixed circular plate 6. The output shaft of the drive motor is connected to the bearing between the fixed circular plate 6 and the moving circular plate 7. When the drive motor on the top of the fixed circular plate 6 is started, it can drive the fixed circular plate 6 to rotate through the output shaft. This allows the moving circular plate 7 to rotate freely relative to the fixed circular plate 6, thereby realizing the rapid switching of different models of stamping heads 9. This linkage mechanism not only improves work efficiency and reduces downtime, but also ensures the accuracy of positioning for each rotation, improving the overall operating accuracy and reliability of the equipment. Several sets of guide shafts are arranged around the bottom of the moving circular plate 7. 15. The connection between the top end of the guide shaft 15 and the bottom of the moving circular plate 7 is fixed by screws. Each group of guide shafts 15 has two positions located on both sides of the punch head 9, and both sides of the top end of the punch head 9 are provided with guide sleeves that cooperate with the structure of the guide shaft 15. When a single punch head 9 performs a punching operation, the guide sleeves on both sides of its top end can cooperate with the guide shaft 15, allowing the punch head 9 to move precisely up and down along the guide shaft 15. This not only ensures the linear motion trajectory of the punch head 9 during operation, reducing the risk of deviation or tilting, but also improves the stamping accuracy and consistency by limiting its movement direction. The coupling 5 is in Two fixed rings are symmetrically welded to the top of the fixed circular plate 6, and connecting rings connected to the coupling 5 are welded to both sides of the bottom of the base 4. Locking bolts are threaded onto these connecting rings. When the device is running, the base 4 transmits power from the fixed circular plate 6 to the moving circular plate 7 and its related components through the connecting rings and coupling 5, ensuring synchronous operation of the entire system. The locking bolts make the connection between the connecting rings and the coupling 5 more secure, effectively preventing loosening due to vibration or impact. This improves the overall rigidity and stability of the system and reduces errors caused by unstable connections, thereby enhancing the precision and consistency of the stamping operation.
[0018] Working Principle: When using this valve head forming stamping device, firstly, the fixed circular plate 6 and the moving circular plate 7 are connected to the connecting rings on both sides of the bottom end of the base 4 through two couplings 5, and the connection is secured by locking bolts. Then, the drive motor on the top of the fixed circular plate 6 is started, allowing the moving circular plate 7 to rotate freely relative to the fixed circular plate 6 to select one of the four stamping heads 9 suitable for different valve models. Thus, according to the valve model to be processed, the moving circular plate 7 quickly rotates and positions itself to the appropriate stamping head 9. Next, the two side frames drive the lifting frame 3 to move up and down through guide rails, allowing the base 4 to be adjusted in height as needed to ensure the accuracy of the stamping process. When the base 4 is adjusted to the correct position, the entire stamping mechanism, including the pressure rod 12, the pressure cylinder 10, and the compression spring 11, descends synchronously. The pressure cylinder 10 first contacts the table surface of the stamping base 1. As the pressure increases, the pressure cylinder 10 moves along the pressure rod 12 towards... The upward movement causes the compression spring 11 to be compressed. At the same time, the guide shaft 15 cooperates with the guide sleeves on both sides of the top of the stamping head 9 to ensure that the stamping head 9 can move up and down precisely along the guide shaft 15. When the stamping head 9 reaches the predetermined position, it begins to stamp the valve to be formed placed on the bottom mold base 2. After the stamping is completed, the lifting frame 3 drives the entire stamping mechanism to rise and return to the initial position to prepare for the next operation. If it is necessary to adjust the compression degree of the compression spring 11 to control the buffer force, it can be achieved by rotating the adjusting bolt 14. Rotating the adjusting bolt 14 causes the lower pressure block 1401 to move downward and contact the notch on the top of the receiving block 1301, thereby pushing the control ring 13 to move downward along the pressure rod 12, causing the compression spring 11 to be compressed to the required degree. The whole process is efficient, precise and stable, meeting the needs of modern production lines, and thus completing a series of tasks.
