[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] The utility model provides a high wear-resistant die punch, such as Figure 1-Figure 7 As shown, the punch 1, the bottom end of the punch 1 is rotatably connected to the upper gear plate 7, the bottom end of the upper gear plate 7 is fixedly connected to the rotating shaft 8, the bottom end of the rotating shaft 8 is rotatably connected to the lower gear plate 9, the bottom end of the upper gear plate 7 is fixedly connected to the first gear 4, the top of the lower gear plate 9 is fixedly connected to the boss 11, the bottom end of the first gear 4 is rotatably connected to the boss 2 16, the surfaces of the boss 2 16 and the boss 1 11 are provided with a plurality of slide grooves 13, the inside of the slide groove 13 is movably connected to the rack 6, one end of the rack 6 is fixedly connected to the small boss 12, one end of the rack 6 is fixedly connected to the limiting block 10, the bottom end surface of the rotating shaft 8 is fixedly connected to the connecting protrusion 14, the surface of the connecting protrusion 14 is clamped and connected to the punch rod 2, the top end of the lower gear plate 9 is rotatably connected to the support column 18 and the support column 18 passes through the lower gear plate 9, the support column 1 The surface of 8 is snap-connected with a gear lock 17, and one end face of the gear lock 17 is snap-connected with the first gear 4. The gear lock 17 and the first gear 4 form a ratchet pawl structure, and one end face of the lower gear plate 9 is rotatably connected with several second gears 5. The pawl end of the gear lock 17 is snap-connected with the first gear 4. When the first gear 4 is rotated, the leaf spring 19 makes the pawl of the gear lock 17 continuously fit with the internal gear of the first gear 4, thereby achieving the goal of only allowing the first gear 4 to rotate in a preset direction, thereby effectively preventing the first gear 4 from rebounding. The support column 18 at the bottom end of the lower gear plate 9 is rotated by the screw to rotate the gear lock 17. The rotating gear lock 17 cannot get stuck with the first gear 4, so that the gear lock 17 can rotate freely, making it more flexible and portable when installing or replacing the punch 1.

[0025] like Figure 2-Figure 7As shown, a leaf spring 19 is fixedly connected to the surface of boss 11, and one end face of the leaf spring 19 fits into the outer side of the gear lock 17. Boss 2 16 is fixedly connected to the top of the lower gear plate 9, so that boss 2 16 and the lower gear plate 9 are effectively fixed, so that the first gear 4 can rotate on boss 2 16, ensuring the smooth rotation of the first gear 4 during operation.

[0026] like Figure 3-Figure 7 As shown, the top end of the second gear 5 is meshed with the first gear 4, and the bottom end of the second gear 5 is meshed with the rack 6. The second gear 5 is rotated by rotating the first gear 4, and the rotation of the second gear 5 causes the rack 6 to move, so that the rotation of the first gear 4 drives the six racks 6 to move synchronously, thereby realizing the synchronous movement of the six racks 6, effectively avoiding the imbalance and motion errors that may be caused by the operation of the gears alone, thereby improving the positioning accuracy of the internal structure.

[0027] like Figure 5 and Figure 6 As shown, a connecting groove 15 is provided on one end face of the punch rod 2, and the surface inside the connecting groove 15 is rotatably connected to the surface of the connecting protrusion 14. By separating and replacing the connecting groove 15 and the connecting protrusion 14, the convenience of replacing the punch rod 2 is improved.

[0028] like Figures 2 to 7 As shown, the number of the second gears 5 is set to six, and the six second gears 5 are arranged in an equidistant circular array with the center of the rotating shaft 8. The six second gears 5 in the equidistant circular array enable the rotation of the first gear 4 to drive all the second gears 5 to rotate, effectively avoiding the single-point high stress problem and improving the overall efficiency of the system.

[0029] like Figure 1 and Figure 2 As shown, the bottom end of the punch rod 2 is fixedly connected with a punch needle 3. Since the connection between the punch rod 2 and the punch needle 3 is firm, the stability of the punch 1 is effectively improved and the defective rate of the stamping product caused by inaccurate guidance is reduced.

[0030] Working principle: put the punch 1 into the punch slot inside the device, and rotate the punch rod 2 to drive the connecting protrusion 14 to rotate, and the rotation of the connecting protrusion 14 drives the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the upper gear plate 7 to rotate, and the upper gear plate 7 drives the first gear 4 to rotate, and the rotation of the first gear 4 drives the second gear 5 to rotate, and the rotation of the second gear 5 drives the rack 6 to move, and the movement of the rack 6 drives the limit block 10 to move, so that the limit block 10 and the device for installing the punch 1 are squeezed and fixed, and finally the punch 1 is limited and fixed by the limit block 10. Since a gear lock 17 is installed on the surface of the lower gear plate 9, and the gear lock 17 is limited by the leaf spring 19 The first gear 4 is in the correct position, which can effectively prevent the first gear 4 from rebounding, thereby achieving absolute driving directional restriction on the first gear 4, ensuring the precise position of the punch 1 inside the device, and rotating the gear lock 17 by rotating the support column 18, so that the gear lock 17 is squeezed toward the position of the leaf spring 19. At this time, since the pawl end of the gear lock 17 leaves the gear end of the first gear 4, the gear lock 17 cannot be engaged with the first gear 4, so that the first gear 4 can be rotated in the opposite direction, so that the limit block 10 can be recovered, thereby ensuring that the position of the punch 1 is accurately controlled, and the first gear 4 can be flexibly adjusted for recovery, so that the position of the punch 1 is easy to adjust during use;

[0031] When the punch rod 2 is damaged, the connecting protrusion 14 and the connecting groove 15 need to be separated and the punch rod 2 needs to be replaced, so that the punch rod 2 can be quickly replaced when the punch rod 2 is damaged. The damaged punch rod 2 can be replaced efficiently, which simplifies the replacement process and improves work efficiency.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
