[0022] An annular boss 12 for preventing the stamping turntable 5 from falling off is provided on the outer side wall of the upper half of the stamping turntable 5, and a connecting shaft 14 extending to the top of the fixing block 7 is provided at the top of the stamping turntable 5. The setting of the annular boss 12 and the connecting shaft 14 is used to prevent the stamping turntable 5 from shifting or tilting during the rotation or descent process, avoiding the punching position from being skewed and affecting the product accuracy. At the same time, by pressing the connecting shaft 14 with the stamping assembly 8, the stamping turntable 5 can bear the corresponding punching force, avoiding damage to the stamping turntable 5 caused by uneven force.

[0023] A top end of the stamping turntable 5 is provided with an upper gear ring 13. A bottom end of an inner side wall of the fixed block 7 is provided with a plurality of rotating gears 15 meshing with the upper gear ring 13. An outer side wall of the fixed block 7 is provided with a second adjusting block 16 penetrating and extending into the fixed block 7. One of the rotating gears 15 is sleeved on an outer side wall of the second adjusting block 16. Through the arrangement of the plurality of rotating gears 15, the pressure transmitted by the stamping turntable 5 is shared. By rotating the second adjusting block 16, the lower stamping turntable 5 is rotated to a corresponding angle, thereby improving the accuracy of the punching position.

[0024] A rack 11 capable of sliding horizontally is arranged inside the stamping turntable 5. A top end of the rack 11 is provided with a second adjusting gear 10 for driving the rack 11 to slide reciprocally. The second adjusting gear 10 is connected with a first adjusting block 9 for controlling the rotation of the second adjusting gear 10. The punching punch 6 is located at a bottom end of the rack 11 and can slide reciprocally inside a groove at a bottom end of the stamping turntable 5. The second adjusting gear 10 is installed inside the stamping turntable 5. A space for the second adjusting gear 10 to rotate is further provided outside the second adjusting gear 10, facilitating the installation of the second adjusting gear 10 and the first adjusting block 9.

[0025] A chute 18 is formed inside the rotating platform 3. The punching die 19 is located inside the chute 18. An outer side wall of the punching die 19 is connected with an adjustable-distance threaded rod 20 capable of rotating. The adjustable-distance threaded rod 20 is located inside the rotating platform 3 and forms a threaded connection. The adjustable-distance threaded rod 20 can drive the punching die 19 to slide reciprocally along a length direction of the chute 18. The support plate 4 is arranged above the rotating platform 3. Through the arrangement of the support plate 4, the chute 18 inside the rotating platform 3 is covered, avoiding the problem of product precision decline during the stamping process.

[0026] A lower gear ring 17 is arranged on an outer side wall of the rotating platform 3. A rotatable first adjusting gear 2 is installed on an outer side wall of the base 1. The first adjusting gear 2 meshes with the lower gear ring 17. The first adjusting gear 2 can drive the rotating platform 3 to rotate. Through the meshing of the lower gear ring 17 and the first adjusting gear 2, the rotating platform 3 can be moved to a required angle according to needs, enabling the positions of the punching punch 6 and the punching die 19 to correspond, thereby avoiding damage to the die.

[0027] The utility model, through the settings of the rack 11 and the distance-adjusting threaded rod 20, can realize the adjustment of the punching punch 6 and the punching die 19 along the length direction. By controlling the rotation of the upper tooth ring 13 and the lower tooth ring 17, the adjustment of the punching punch 6 and the punching die 19 along the circumferential direction is realized, so as to realize the arbitrary adjustment of the punching punch 6 and the punching die 19 within the circumferential range. Therefore, when the punching design in the progressive die is unreasonable, the position of the punching die 19 and the punching punch 6 can be adjusted to adjust the hole position, thereby reducing the research and development and maintenance costs of the die and avoiding the problem of product defects caused by unreasonable hole position settings.

[0028] The above are only the preferred embodiments of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the utility model.
