[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please refer to Figure 1 The present invention provides a punch assembly structure that is easy to install and disassemble, including a punch 1, a retainer 2, a retaining ring 3, and a retaining member 4. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the bottom end of the punch 1 may be provided with a first protruding ring 11, and the top end of the card holder 2 is provided with a second protruding ring 21. The bottom surface of the first protruding ring 11 is in contact with the top surface of the second protruding ring 21. The inside of the snap-fit ​​4 is hollow and both ends are through. The snap-fit ​​4 is fixedly sleeved on the outside of the first protruding ring 11 and the second protruding ring 21.

[0021] The holder 2 provides stable support for the punch 1. Through the contact between its second protruding ring 21 and the first protruding ring 11 of the punch 1, as well as the interaction with the retaining member 4, the punch 1 is positioned in the assembly structure, ensuring the stability of the punch 1 during stamping, making it less prone to displacement, and thus improving stamping accuracy.

[0022] like Figure 3 As shown, specifically, the snap-fit ​​component 4 may include a first snap-fit ​​block 41 and a second snap-fit ​​block 42 with a semi-cylindrical structure. The middle parts of the first snap-fit ​​block 41 and the second snap-fit ​​block 42 are respectively provided with a first snap-fit ​​groove 411 and a second snap-fit ​​groove 421 for stacking the first convex ring 11 and the second convex ring 21. The cross-sectional parts of the first snap-fit ​​block 41 and the second snap-fit ​​block 42 are fixedly connected to each other, and the snap-fit ​​ring 3 is fixedly sleeved on the outside of the first snap-fit ​​block 41 and the second snap-fit ​​block 42.

[0023] Preferably, the first locking block 41 and the second locking block 42 can be fixedly connected by screw locking or snap-fit ​​connection.

[0024] like Figure 4As shown, in this embodiment, the snap-fit ​​member 4 can be provided with a first limiting ring portion 401, a convex ring receiving portion 402 and a second limiting ring portion 403 from top to bottom. The first limiting ring portion 401 and the second limiting ring portion 403 are respectively formed and disposed at the upper and lower ends of the convex ring receiving portion 402. The top surface of the first convex ring 11 abuts against the bottom surface of the first limiting ring portion 401, and the bottom surface of the second convex ring 21 abuts against the top surface of the second limiting ring portion 403.

[0025] The combination of the first slot 411 and the second slot 421 provides a accommodating space for the first convex ring 11 and the second convex ring 21. The first limiting ring portion 401 and the second limiting ring portion 403 respectively abut against the top surface of the first convex ring 11 and the bottom surface of the second convex ring 21, which can be used to limit the displacement of the punch 1 and the card seat 2 in the axial direction.

[0026] In order to fix the retaining ring 3 to the retaining member 4, a number of screw holes 31 can be provided at intervals around the outer side wall of the retaining ring 3.

[0027] Preferably, an annular positioning portion 43 is recessed inward on the middle of the outer side wall of the snap-fit ​​member 4, corresponding to the position of each screw hole 31.

[0028] In practice, by using multiple locking screws to connect with each screw hole 31 and abut against the annular positioning part 43 of the snap fastener 4, the snap ring 3 can be fastened to the snap fastener 4, thereby firmly fixing the first snap block 41 and the second snap block 42 together and preventing the snap fastener 4 from loosening.

[0029] like Figure 5 As shown, it may also include a middle template 5, a middle mold 51, a fixing plate 6, a mounting base 61, a mandrel plate 7, and a mandrel guide post 71. The mandrel guide post 71 is fixedly connected between the bottom surface of the middle template 5 and the top surface of the mandrel plate 7. The fixing plate 6 is fixedly inserted through the mandrel guide post 71 and located between the middle template 5 and the mandrel plate 7. The mounting base 61 is embedded in the top of the fixing plate 6. The bottom end of the card seat 2 is provided with a third protruding ring 23. The third protruding ring 23 is fixedly installed on the mounting base 61. The middle mold 51 is fixedly embedded in the middle part of the middle template 5. The middle mold 51 has a forming hole for the upper part of the punch 1 to pass through.

[0030] The middle mold 51 has a forming hole through which the upper part of the punch 1 passes, which can guide and restrict the punching direction of the punch 1 and prevent the upper part of the punch 1 from deviating. The upper structure of the punch 1 can be flexibly adjusted according to actual needs, and its upper shape, size and other structural parameters are not restricted in this embodiment.

[0031] Furthermore, to ensure the relative position of the card holder 2 is fixed, this embodiment may also include a card holder pressing block 8. The card holder pressing block 8 is arranged in an inverted L-shaped structure. The vertical section of the card holder pressing block 8 abuts against the top surface of the mounting base 61, and the horizontal section of the card holder pressing block 8 abuts against the top surface of the third protruding ring 23 of the card holder 2. A first fixing hole 80 is provided on the horizontal section of the card holder pressing block 8, and a plurality of second fixing holes 610 are provided around the top of the mounting base 61.

[0032] In practice, the locking screw passes through the first fixing hole 80 and is threaded into the second fixing hole 610, thereby fixing the card holder block 8 to the mounting base 61. This further tightens the card holder 2, preventing it from loosening or shifting during operation. Furthermore, the card holder 2 effectively disperses the pressure generated by the punch 1 during operation, protecting the entire assembly structure and extending its service life.

[0033] In summary, this utility model uses two locking blocks of the snap-fit ​​component to be fixedly sleeved on the outside of the contact area between the punch and the card holder, and the two locking blocks are locked and fixed by the snap ring. This can prevent the punch and the card holder from shifting vertically or loosening at the connection point, and ensure that the relative position between the two remains unchanged. This ensures the stability and accuracy of the entire punch assembly. This utility model achieves rapid installation and disassembly of the punch while ensuring the punching accuracy, and significantly improves the efficiency of assembly and disassembly.

[0034] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
