[0002] Disc springs, also known as Belleville spring washers, are conical discs that can be used individually or in series or in parallel. They bear static or dynamic loads acting in the axial direction at the upper inner edge and the lower outer edge. They are deformed after being compressed until they are flattened, storing energy as live loads. When necessary, they are automatically converted into additional compression loads required for sealing to reduce the continuous tightening requirements of gaskets and packings.

After the moving part 104 is moved out, when the pushing pin 404 slides downward along the oblique slot 403, it can drive the moving part 104 to move obliquely downward; At the same time, as the moving part 104 moves away, under the action of the first spring 602, the third moving block 1202 can be driven to move away from the support plate 1201, and the moving ring 1203 and the grinding sleeve 1204 can be driven to move synchronously through the second lifting mechanism 7, and when the grinding sleeve 1204 is driven to align with the center of the fixed part 103, under the action of the second spring 703, the grinding sleeve 1204 can be driven to move upward and abut against the bottom of the stamped disc spring body, and when the push pin 404 continues to slide downward along the inclined groove 403, the first pushing block 811 and the pushing frame 8 The side walls of the first gear 809 abut against each other, and the first rack 809 can be driven to move toward the support block 806. At the same time, the third spring 810 is compressed and can push the second gear 805 to rotate. When the second gear 805 rotates, the rotating shaft 803 and the first gear 804 can be driven to rotate, and then the grinding sleeve 1204 can be driven to rotate, so that the bottom of the disc spring body after stamping can be polished to form a supporting surface, so that the supporting surface can be automatically processed on the bottom of the disc spring body after stamping, which is more convenient and quick to use and can improve the efficiency of disc spring processing; After the grinding is completed, the second push block 1013 can pass over the second push plate 1004, and after the reset spring 203 is reset, the punch 105 can move upward. After the second push block 1013 passes over the second push plate 1004, the fourth moving block 907 can move and reset under the action of the fourth spring 904, thereby driving the moving frame 905 and the second rack 906 to move and reset, and can push the first moving block 301 to move upward, and at the same time push the pin 404 to move upward along the inclined groove 403, until the moving part 104 abuts against the side wall of the grinding sleeve 1204. When the moving part 104 continues to move and is aligned with the bottom center of the fixed part 103, the polishing sleeve 1204 can be pushed to move, and the third moving block 1202 is driven by the second lifting mechanism 7 to move toward the support plate 1201. The first spring 602 is compressed. When the push pin 404 moves upward along the first vertical groove 402, the moving part 104 can be moved into the fixed part 103 for subsequent stamping operations.
