DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figure 1-Figure 4 The present application provides a positioning structure of a high-speed rotary die, including a frame 10, a turntable 20, an impact mechanism 30, a translation mechanism 40, an intermittent mechanism 50 and an upper die 60. The turntable 20 has a lower die 70 in a circular array. The impact mechanism 30 is movably connected to the upper die 60 through the translation mechanism 40. The turntable 20 is connected to the impact mechanism 30 through the intermittent mechanism 50. The upper die 60 is provided with a positioning pin 80 adapted to the lower die 70. Among them, the impact mechanism 30 drives the turntable 20 to rotate through the intermittent mechanism 50, thereby playing a basic synchronization role. The translation mechanism 40 is used to allow the upper die 60 to adjust itself according to the correction torque of the positioning pin 80, thereby ensuring the accuracy of the mold clamping.

[0025] See also Figure 1-Figure 4 The impact mechanism 30 includes a guide rod 31, a connecting rod 32 and an eccentric wheel 33. The guide rod 31 is slidably connected to the frame 10, and the upper end of the guide rod 31 is connected to the eccentric wheel 33 through the connecting rod 32. The impact mechanism 30 also includes a motor 34, which is connected to the eccentric wheel 33. The motor 34 drives the eccentric wheel 33 to rotate, and drives the guide rod 31 to move vertically up and down through the connecting rod 32 to produce a stamping effect.

[0026] See also Figure 1-Figure 4 The translation mechanism 40 includes an outer shell 41 and an inner disk 42. The inner disk 42 is horizontally slidably connected to the inner shell 41. The inner disk 42 is fixedly connected to the lower end of the guide rod 31. The outer shell 41 is fixedly connected to the upper mold 60. A spring 43 is arranged between the outer shell 41 and the inner disk 42. The upper mold 60 can move within a certain plane range relative to the guide rod 31, so that the positioning pin 80 can be used to correct the deviation by itself to ensure the accuracy of the mold clamping. The spring 43 is used to drive the inner disk 42 to return to the center position.

[0027] See also Figure 1-Figure 4The intermittent mechanism 50 includes a dial wheel 51 and a groove wheel 52, the dial wheel 51 is movably engaged with the groove wheel 52, the dial wheel 51 is connected to the shaft of the motor 34, and the groove wheel 52 is connected to the shaft of the turntable 20. The dial wheel 51 and the groove wheel 52 form a Malta mechanism to achieve intermittent transmission. When the motor 34 rotates, the turntable 20 can be driven to rotate synchronously, thereby playing a basic synchronization role.

[0028] See also Figure 1-Figure 4 The frame 10 is also provided with a transmission member 90, which includes a main gear 91 and a slave gear 92. The main gear 91 is connected to the shaft of the motor 34, and the slave gear 92 is connected to the shaft of the dial 51. The transmission member 90 also includes a gear rod 93, and the two ends of the gear rod 93 are respectively meshed with the main gear 91 and the slave gear 92. The output end of the motor 34 transmits power to the dial 51 through the main gear 91, the gear rod 93 and the slave gear 92, thereby driving the turntable 20 to rotate intermittently.

[0029] The working principle of the positioning structure of the high-speed rotary die is as follows: the motor 34 drives the eccentric wheel 33 to rotate, and transmits power to the dial wheel 51 through the main gear 91, the gear rod 93 and the slave gear 92, thereby driving the turntable 20 to rotate intermittently, and at the same time, the connecting rod 32 pushes the guide rod 31 to drive the upper mold 60 to move downward. If there is an offset between the upper mold 60 and the lower mold 70, the positioning pin 80 is used to correct the offset. Since the inner disk 42 can move laterally in the outer shell 41, the upper mold 60 can move laterally following the correction torque, thereby ensuring the accuracy of the mold closing. In summary, the impact mechanism 30 drives the turntable 20 to rotate through the intermittent mechanism 50, thereby playing a basic synchronization role. The translation mechanism 40 is used to allow the upper mold 60 to adjust itself according to the correction torque of the positioning pin 80, thereby ensuring the accuracy of the mold closing.
