[0009] As a preferred technical solution, the upper die assembly includes an upper die and a punch block;

[0010] A fixing hole is arranged at one end of the upper die, and the punching block is inserted into the fixing hole; a threaded hole is processed at one side of the upper die, and a bolt is arranged in the threaded hole, and the punching block and the upper die are fixed by the bolt.

[0011] As a preferred technical solution, the outer diameter of the spring is 8 mm and the length is 15 mm.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model optimizes the traditional hammer punch to use a riveting machine to complete the processing, thereby improving production efficiency, and the processed product angle, size is stable, and the appearance is beautiful.

[0014] 2. The utility model has a simple structure, which is divided into an upper mold and a lower mold. The mold has a simple structure, low cost, convenient assembly, stable performance, and can be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0027] like Figure 1-Figure 3As shown, a new type of riveting die of the utility model comprises a lower die assembly 1, on which a punch 3 is elastically mounted;

[0028] It also includes an upper die assembly 2 on which a punch block 4 is fixed. During processing, the upper die assembly 2 moves downward, the lower die assembly 1 is subjected to force, and is positioned by the punch pin 3 of the lower die assembly 1.

[0029] like Figure 4-Figure 6 As shown, the lower die assembly 1 includes a lower die 9 and a punch 3. The lower die 9 is hollow inside to form a spring groove 5, and the punch 3 is guided in the spring groove 5, and the end of the punch 3 is arranged through one end of the lower die 9; the other end of the lower die 9 is threadedly connected with a locking piece 6, and a spring 7 is arranged between the locking piece 6 and the punch 3; wherein, the precision of the punch is +0.02mm.

[0030] like Figure 7-Figure 8 As shown, the upper die assembly 2 includes an upper die 10 and a punching block 4; a fixing hole is provided at one end of the upper die 10, and the punching block 4 is inserted into the fixing hole; a threaded hole is processed on one side of the upper die 10, and a bolt 8 is provided in the threaded hole, and the punching block 4 is fixed to the upper die 10 by the bolt 8; wherein, the precision of the punching block 4 is -0.02mm.

[0031] In addition, the spring 7 has an outer diameter of 8 mm and a length of 15 mm.

[0032] Here’s how it works:

[0033] During processing, the upper die moves downward, the lower combined die is stressed, and the punch pin of the lower die is positioned; when the spring in the lower die is subjected to the pressure of the upper die, the punch pin will shrink and avoid the position, the lower die supports the parts, and the upper die punch can make the parts stably pressurized and formed to complete the self-riveting task.

[0034] The traditional hammer punch processing method (two-person operation) is costly, inefficient, unstable in product quality, and the punch is prone to wear;

[0035] The utility model adopts split installation, has low processing cost and stable structure, and is suitable for assembling products requiring self-riveting.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
