[0008] As a preferred solution of the present invention, the outer wall of the positioning ring is provided with a gear ring, the inner wall of the positioning ring is provided with a plurality of guide blocks for fixing the plate, the top of the lower fixed plate is installed with a rotatable rotating gear engaged with the gear ring, and the circular plate is positioned and installed on the top of the stop block through the guide block.

[0009] As a preferred solution of the present invention, the upper fixed plate and the lower fixed plate are detachably connected through a plurality of support columns, the upper mold is detachably mounted on the bottom end of the ejection plate, and a connecting rod passing through the upper fixed plate is provided at the center position of the upper fixed plate, and the connecting rod can drive the ejection plate to slide longitudinally.

[0010] As a preferred solution of the present invention, a plurality of protrusions penetrating the upper fixed plate are provided at positions where the ejection plate and the positioning ring are matched, and the ejector rods slide back and forth in grooves provided inside the protrusions of the ejection plate.

[0011] As a preferred solution of the present invention, an ejection spring is provided on the top of the ejector rod, and the end surface of the bottom of the ejector rod that contacts the positioning ring is made of rubber material.

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] The utility model provides Figure 1-4 The circular stamping plate rotating device shown in the figure comprises a lower fixed plate 1, an upper fixed plate 3 located at the top of the mold and a circular plate 10 for stamping, the top of the lower fixed plate 1 is provided with a lower mold 14 for blanking, the outer side of the lower mold 14 is provided with a rotatable pressure bearing 12, the top of the pressure bearing 12 is detachably connected to a rotatable positioning ring 2, the bottom end of the inner side wall of the positioning ring 2 is provided with a stopper 17 that fits with the outer side wall of the lower mold 14, the bottom end of the upper fixed plate 3 is provided with an upper mold for stamping Mold 7, the outer side wall of the upper mold 7 is provided with multiple push rods 8 for fixing the positioning ring 2, and the detachable setting of the top end of the pressure bearing 12 and the positioning ring 2 can increase the dead weight of the positioning ring 2, so that the positioning ring 2 can avoid falling off and tilting during the rotation process. Through the setting of the stop block 17, the inner side wall of the stop block 17 can be fitted with the lower mold 14 to improve the rotation accuracy of the positioning ring 2. By ensuring that the bottom end of the circular plate 10 is tightly fitted with the top end of the lower mold 14, gaps are avoided, which affects the punching accuracy.

[0022] The outer wall of the positioning ring 2 is provided with a gear ring 15, and the inner wall of the positioning ring 2 is provided with a plurality of guide blocks 13 for fixing the plate. The top of the lower fixed plate 1 is provided with a rotatable rotating gear 6 meshing with the gear ring 15. The circular plate 10 is positioned and installed on the top of the stop block 17 through the guide block 13. The setting of the guide block 13 is used to ensure that the circular plate 10 can rotate synchronously with the positioning ring 2 during the rotation of the positioning ring 2, thereby achieving the purpose of multi-stage stamping. If it is necessary to use multi-stage stamping to process the circular plate 10, it may be necessary to control the falling height of the upper mold 7 at different levels after replacing the circular plate 10 to avoid process errors during the stamping process, resulting in part processing failure and waste of materials.

[0023] The upper fixed plate 3 and the lower fixed plate 1 are detachably connected through a plurality of support columns 4. The upper die 7 is detachably mounted on the bottom end of the ejector plate 11. A connecting rod 5 penetrating the upper fixed plate 3 is provided at the center of the upper fixed plate 3. The connecting rod 5 can drive the ejector plate 11 to slide longitudinally. The setting of the ejector plate 11 can ensure that the ejector rod 8 contacts the positioning ring 2 first while fixing the upper die 7, and can fix the position of the positioning ring 2 before the stamping process, thereby avoiding a reduction in stamping accuracy and waste of workpieces.

[0024] The position where the ejection plate 11 is adapted to the positioning ring 2 is provided with a plurality of protrusions that pass through the upper fixed plate 3. The ejector rod 8 is located in the groove opened inside the protrusion of the ejection plate 11 and slides back and forth. In order to have enough stroke for the ejector rod 8 to slide, a protrusion is provided to ensure the sliding stroke of the ejector rod 8. The setting of the protrusion passing through the upper fixed plate 3 can effectively reduce the thickness of the position where the upper mold 7 is located, reduce the materials required for production, and reduce production costs.

[0025] An ejection spring 9 is provided at the top of the ejector rod 8, and the end surface of the bottom of the ejector rod 8 that contacts the positioning ring 2 is made of rubber material. The rubber material has good elasticity and can still restore its original shape after multiple compression deformations, ensuring that the positioning ring 2 can still be positioned after multiple stampings.

[0026] An ejection device 16 for ejecting the circular plate 10 is provided at the center of the lower mold 14. The ejection device 16 can be removed through the ejection device 16 after the circular plate 10 is processed, which facilitates the replacement of the circular plate 10 and reduces the difficulty of operating the equipment.

[0027] In the present invention, the upper die 7 and the lower die 14 can adopt the form of a progressive die, and multiple punching modules can be set. The circular plate 10 is driven to rotate by the positioning ring 2. When complex annular blanking parts are required, more complex blanking patterns can be obtained by rotating multiple simpler upper dies 7 and lower dies 14. The complexity of the die directly affects the production cost. Fewer die require less storage space, which reduces the production cost. By reducing the complexity of the die, the maintenance cost of the die can also be greatly reduced. Through the setting of the ejector rod 8, in the process of the upper die 7 stamping downward, the ejector rod 8 first contacts the positioning ring 2 under the action of the ejection spring 9, and the positioning ring 2 is squeezed by the rubber material at the bottom of the ejector rod 8 to prevent the positioning ring 2 from rotating during the stamping process, affecting the forming accuracy of the part. The setting of the stop block 17 can limit the rotation position of the positioning ring 2 on the premise of ensuring that the lower die 14 is in contact with the circular plate 10, to prevent the rotation accuracy from being too low, which affects the effect of the formed part.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
