[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] For example, see Figures 1 - 3 The utility model provides a technical solution, a punching die and a precision sheet metal production device: including

[0022] Base 1, on which a blanking table 3 is provided. A number of blanking openings 5 are provided through the blanking table 3. The blanking openings 5 are used for cleaning and recycling the waste materials after blanking. A number of clamping members 6 are evenly arranged on both sides of the blanking openings 5 on the blanking table 3. The clamping members 6 are used to fixedly clamp the workpieces, ensuring the stability of the workpieces during sheet metal processing and avoiding inaccurate processing caused by shaking. A hydraulic rod 7 is provided on the base 1, and the hydraulic rod 7 is arranged at the four corners of the base 1;

[0023] Blanking plate 2, on which a number of limiting holes 14 are evenly arranged. A cushion layer 8 is provided on the blanking plate 2. A number of blanking knives 9 are provided on the cushion layer 8. The blanking knives 9 process the sheet metal parts. The blanking openings 5 are correspondingly arranged with the blanking knives 9. A hydraulic cylinder 71 is provided on the blanking plate 2, and the hydraulic cylinder 71 is arranged in one-to-one correspondence with the hydraulic rod 7. The hydraulic mechanism controls the cutting depth of the blanking knives 9 to ensure complete cutting and no adhesion of waste materials. A spring mechanism 10 is provided on the cushion layer 8. When the hydraulic mechanism presses down, the spring mechanism 10 enables the blanking plate 4 and the blanking table 3 to be preferentially fitted to fix the sheet metal parts. As the hydraulic mechanism presses down, it controls the blanking knives 9 to process the sheet metal parts. After blanking processing, the blanking plate 4 and the blanking table 3 are separated, and the spring mechanism 10 assists the blanking knives 9 to rebound. The spring mechanism 10 and the blanking plate 4 play a function of first stabilizing and then cutting.

[0024] On one side of the clamping member 6 close to the blanking opening 5, a clamping groove 62 is provided, and the clamping groove 62 is used for clamping and fixing the sheet metal parts.

[0025] The blanking plate 4 is provided with a through hole, and the blanking knife 9 is arranged in the through hole. A number of grooves 61 are provided on the blanking plate 4, and the grooves 61 are adapted to the clamping members 6. The grooves 61 ensure that the blanking table 3 and the blanking plate 4 can be closely attached during blanking processing.
