[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0019] Example 1 According to an embodiment of the present invention, a character inlay structure is provided. Figures 4 to 11 , including: a punching block, the punching block includes a punching surface 111, and the punching surface 111 is provided with concave or convex inlay characters 2, which is used to stamp the required characters on the plate 30, wherein the punching surface 111 includes multiple; a mounting component, the mounting component is used to carry the punching block; a fixing structure, the fixing structure is used to install the punching block on the mounting component, the punching block is detachably connected to the mounting component through the fixing structure, so as to switch the punching surface 111 of the stamped plate 30.

[0020] By setting a punching block, the punching block includes multiple punching surfaces 111. By setting a mounting component, the punching block is detachably connected to the mounting component through a fixed structure, so that the punching block can be quickly disassembled to replace different punching surfaces 111. When the insert character 2 on one of the punching surfaces 111 is damaged, it can be quickly replaced with other punching surfaces 111 to continue using the current punching block, avoiding the need to replace a new punching block. A reusable character insert structure is realized, which reduces processing costs and avoids production delays. The technical problem in the related art that the punch character block's convex or concave mold characters are easily damaged during production, resulting in increased processing costs and production delays is solved.

[0021] In the character insert structure of this embodiment, see Figure 5 or Figure 6The fixing structure includes a fastener 31 and a through hole 32 provided on the punching block, the through hole 32 is used for the fastener 31 to pass through, and a threaded hole 33 is provided in the mounting component, and the fastener 31 passes through the through hole 32 and is connected to the threaded hole 33. Through the above arrangement, the fastener 31 passes through the through hole 32 and is threadedly connected to the mounting component, thereby achieving the fixing and quick disassembly of the punching block.

[0022] In the character insert structure of this embodiment, see Figure 5 The through hole 32 includes a first through hole 321 and a second through hole 322, and the punching block includes: a first punching surface 1111 and a third punching surface 1113 arranged opposite to the first punching surface 1111, and the first through hole 321 is penetrated between the first punching surface 1111 and the third punching surface 1113; a second punching surface 1112 and a fourth punching surface 1114 arranged opposite to the second punching surface 1112, and a second through hole 322 is penetrated between the second punching surface 1112 and the fourth punching surface 1114; wherein, an extension direction of the first through hole 321 is perpendicular to an extension direction of the second through hole 322. Through the above arrangement, the first punching surface 1111 and the third punching surface 1113 are two oppositely arranged surfaces, and the first punching surface 1111 and the third punching surface 1113 share the first through hole 321; the second punching surface 1112 and the fourth punching surface 1114 are two oppositely arranged surfaces, and the second punching surface 1112 and the fourth punching surface 1114 share the second through hole 322, thereby simplifying the structure and improving the structural strength of the punching block.

[0023] Preferably, the punching block is a cuboid. In addition to the above four faces, inlaid characters 2 can also be added on the remaining two side faces of the cuboid to improve the utilization efficiency of the punching block.

[0024] It is understandable that the punch block can also be designed as a polygon or other shape structure according to actual needs.

[0025] Preferably, the insert character 2 is centered on the punching surface, and the distances between the axes of the first through hole 321 and the second through hole 322 and the insert character 2 are the same, but the axes of the first through hole 321 and the second through hole 322 are perpendicular to each other, which facilitates the operator to operate the fastener when switching to the current punching surface.

[0026] In the character insert structure of this embodiment, see Figure 5-6 The threaded hole 33 includes a first threaded hole and a second threaded hole; a first threaded hole is opened in the mounting component, and the first threaded hole is correspondingly arranged with the first through hole 321 or the second through hole 322; and / or a second threaded hole is opened in the mounting component, and the second threaded hole is correspondingly arranged with the first through hole 321 or the second through hole 322.

[0027] In some embodiments, since the distances between the first through hole 321 and the second through hole 322 and the insert character 2 are the same, the first threaded hole can not only cooperate with the first through hole 321 to fix the punching block, but also when punching some special characters (such as characters that do not require direction or symmetrical fonts), the first threaded hole and the second through hole 322 can be used to fix the punching block after turning the direction of the punching block.

[0028] In the character insert structure of this embodiment, see Figure 8-9 The first punching surface 1111 is provided with a first countersunk hole, and the third punching surface 1113 is provided with a third countersunk hole, and the first countersunk hole and the third countersunk hole are respectively located at two ends of the first through hole 321. With the above arrangement, when the first punching surface 1111 or the third punching surface 1113 is used for punching, the fastener can be hidden in the countersunk hole to prevent the end of the fastener from protruding from the punching surface.

[0029] In the character insert structure of this embodiment, see Figure 10-11 The second punching surface 1112 is provided with a second countersunk hole, and the fourth punching surface 1114 is provided with a fourth countersunk hole, and the second countersunk hole and the fourth countersunk hole are respectively located at two ends of the second through hole 322. With the above arrangement, when the second punching surface 1112 or the fourth punching surface 1114 is used for punching, the fastener can be hidden in the countersunk hole to prevent the end of the fastener from protruding from the punching surface.

[0030] In the character insert structure of this embodiment, see Figure 7 The punch block includes an upper punch block 11, on which a raised insert character 2 is arranged; the mounting component includes a punch 4 for carrying the upper punch block 11, on which a first positioning groove 41 is provided, and in which at least part of the upper punch block 11 is accommodated. Through the above arrangement, the upper punch block 11 is fixed by the punch 4, and the upper punch block 11 is positioned by the first positioning groove 41.

[0031] It can be understood that the shape of the first positioning groove 41 matches the outer shape of the upper die punching block 11 , and the upper die punching block 11 is embedded in the first positioning groove 41 .

[0032] In the character insert structure of this embodiment, see Figure 5 , a threaded hole 33 is provided on the punch 4. Through the above arrangement, when the punch 4 and the upper die punching block 11 are assembled, the upper die punching block 11 and the upper die punching block 11 are assembled into one body, and then the two are assembled into the mold together, thereby reducing the difficulty of assembling the upper die punching block 11.

[0033] It is understandable that the punch 4 can be eliminated and the upper die punching block 11 can be directly fixed to the upper template 53. However, since the upper die punching block 11 has raised insert characters 2, the probability of damage to the upper die punching block 11 is much greater than that of the lower die punching block 12. The punch 4 is used to fix the upper die punching block 11, thereby facilitating the switching of the punching surface 111 of the upper die punching block 11, avoiding excessive cumbersome steps such as demolding, and further improving production efficiency.

[0034] In the character insert structure of this embodiment, see Figure 7 The first positioning groove 41 is provided with an escape groove 42 for avoiding the insert character 2. Since the upper die punch block 11 has a raised insert character 2, it is necessary to increase the escape in the first positioning groove 41 to protect the insert character 2 and prevent the insert character 2 from being damaged by the machine tool and the mold.

[0035] In some embodiments, a threaded hole for connecting with the upper template 53 is provided on the punch 4, and the avoidance groove 42 can be directly set in the threaded hole, or the avoidance groove 42 can be opened separately according to the size or position of the insert character 2.

[0036] In the character insert structure of this embodiment, see Figure 5 The punching block includes a lower die punching block 12, and a recessed insert character 2 is arranged on the lower die punching block 12; the mounting component includes a lower template 51 for carrying the lower die punching block 12 and a lower die seat 52 located below the lower template 51, and a second positioning groove 511 is provided on the lower template 51, and at least part of the lower die punching block 12 is accommodated in the second positioning groove 511, and a threaded hole 33 is provided on the lower die seat 52. Through the above arrangement, the lower die punching block 12 is positioned through the second positioning groove 511.

[0037] It is understandable that the shape of the second positioning groove 511 matches the outer shape of the lower die punching block 12 , and the lower die punching block 12 is embedded in the second positioning groove 511 .

[0038] In some embodiments, the second positioning groove 511 is a through groove provided throughout.

[0039] Example 2 A character stamping die comprises the above-mentioned character insert structure.

[0040] Specifically, the character stamping die also includes an upper template 53, the punch 4 is fixed on the upper template 53 by screws, and the upper template 53 is connected to a stamping machine to stamp characters on the plate.

[0041] In the character stamping die of the present embodiment, a punching block is provided, the punching block includes a plurality of punching surfaces 111, and a mounting component is provided, the punching block is detachably connected to the mounting component through a fixed structure, so that the punching block can be quickly disassembled to replace different punching surfaces 111. When the insert character 2 on one of the punching surfaces 111 is damaged, it can be quickly replaced with other punching surfaces 111 to continue using the current punching block, avoiding the need to replace a new punching block, realizing a reusable character insert structure, reducing processing costs, avoiding production delays, and solving the technical problem in the related art that the punch character block's convex or concave characters are easily damaged during production, resulting in increased processing costs and production delays.

[0042] The specific operation steps of character stamping die are as follows: like Figure 5 and Figure 6 As shown, first, one of the surfaces of the upper die punching block 11 is selected as the working surface and fixed on the punch 4 by screws, and then the punch 4 is fixed on the upper template 53 by screws. Secondly, the lower template 51 and the lower die base 52 are fixed together by screws, and then one of the surfaces of the lower die punching block 12 is selected as the working surface and fixed in the second positioning groove 511 of the lower template 51 by screws.

[0043] like Figure 6 and Figure 7 As shown, the sheet 30 is placed on the lower die plate 51, and as the upper die plate 53 gradually descends, the upper die punch block 11 also descends synchronously until the convex characters on the upper die punch block 11 contact the sheet 30. As the descent continues, the convex characters on the upper die punch block 11 press the sheet 30 and contact the concave characters on the lower die punch block 12. After that, the upper die plate 53 gradually rises, and the upper die punch block 11 also rises synchronously. Finally, the required characters appear on the sheet 30 after stamping.

[0044] During this process, once the convex characters on the upper die punch block 11 or the concave characters on the lower die punch block 12 are damaged, you only need to remove the fastener 31, rotate the upper die punch block 11 or the lower die punch block 12 one face, and fix it with the fastener 31, and then you can continue to use it.

[0045] Example 3 A machine tool comprises the above-mentioned character stamping die. In the machine tool of the present embodiment, a punching block is provided, the punching block includes a plurality of punching surfaces 111, and a mounting component is provided, the punching block is detachably connected to the mounting component through a fixed structure, so that the punching block can be quickly disassembled to replace different punching surfaces 111. When the insert character 2 on one of the punching surfaces 111 is damaged, it can be quickly replaced with other punching surfaces 111 to continue using the current punching block, thereby realizing a reusable character insert structure, avoiding the replacement of new punching blocks, reducing processing costs, and avoiding production delays. The technical problem in the related art that the punch character block's convex characters or concave characters are easily damaged during production, resulting in increased processing costs and production delays is solved. Example 4 Based on any one of the implementations in Examples 1-3, a feasible specific implementation is further proposed.

[0046] In this embodiment, a reusable character insert structure is implemented, which solves the problem of production delays caused by damage to the convex and concave characters, and improves production efficiency.

[0047] The implementation method is as follows: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the structure can be generally composed of screws, an upper template 53, a lower template 51, a lower die base 52, a punch 4, an upper die punching block 11, a lower die punching block 12 and other parts.

[0048] in, Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, in the present embodiment, the four sides of the upper die punching block 11 and the lower die punching block 12, the first punching side 1111, the second punching side 1112, the third punching side 1113, and the fourth punching side 1114 are respectively designed to be corresponding convex characters and concave characters. Once the characters on one of the four sides of the upper die punching block 11 or the lower die punching block 12 are damaged during the production process, they can be immediately replaced with another side for production, which saves costs and improves production efficiency.

[0049] The specific steps are as follows: like Figure 5 and Figure 6 As shown, first, one of the surfaces of the upper die punch block 11 is selected as the working surface and fixed to the punch 4 by the fastener 31, and then the punch is fixed to the upper template 53 by screws. Secondly, the lower template 51 and the lower die base 52 are fixed together by screws, and then one of the surfaces of the lower die punch block 12 is selected as the working surface and fixed in the groove of the lower template 51 by the fastener 31.

[0050] like Figure 6 and Figure 7 As shown, the sheet 30 is placed on the lower die plate 51, and as the upper die plate 53 gradually descends, the upper die punch block 11 also descends synchronously until the convex characters on the upper die punch block 11 contact the sheet 30. As the descent continues, the convex characters on the upper die punch block 11 press the sheet 30 and contact the concave characters on the lower die punch block 12. After that, the upper die plate 53 gradually rises, and the upper die punch block 11 also rises synchronously. Finally, the required characters appear on the sheet 30 after stamping.

[0051] During this process, once the convex characters on the upper die punch block 11 or the concave characters on the lower die punch block 12 are damaged, you only need to remove the fastener 31, rotate the upper die punch block 11 or the lower die punch block 12 one face, and fix it with the fastener 31, and then you can continue to use it.
