A stamping die as claimed in claim 1, wherein: the smashing assembly (14) comprises a collecting box (1401), the collecting box (1401) is fixedly welded on a fixed bottom plate (1), a fixed shaft (1402) is connected in the collecting box (1401) in a rotating mode, a smashing roller (1403) and a circular gear (1404) are fixedly welded on the fixed shaft (1402), and the circular gear (1404) is connected to a gear rod (1303) in a meshed mode.

9. The stamping die of claim 8, wherein: the top end face of the collecting box (1401) is attached to the bottom end face of the placing plate (8), and the length and the width of the inner space at the top end of the placing plate (8) are equal to the diameter of the punching groove (15).

10. A stamping process for a stamping die as claimed in claims 1 to 9, comprising the steps of:

s1: fixing the stamping part; when the hydraulic cylinder (4) drives the sliding plate (6) to move downwards through the hydraulic rod (5), the self-adaptive clamping assembly (9) can be driven to automatically and stably clamp and fix stamping parts of different specifications;

s2: stamping; the sliding plate (6) continues to move downwards to drive the punching head (7) to perform stable punching work on the punching piece, and the punched waste can stably fall into the crushing assembly (14);

s3: automatic demoulding; after the punching work is finished, the sliding plate (6) moves upwards to drive the punching head (7) to be separated from the stamping part, meanwhile, the sliding plate (6) can drive the adaptive clamping assembly (9) to be separated from the stamping part, then the adaptive clamping assembly (9) can drive the automatic demoulding assembly (13) through the second conveying pipe (10), and the punched stamping part can be pushed upwards to finish the automatic demoulding work;

s4: crushing waste materials; automatic drawing of patterns subassembly (13) in the working process can drive crushing unit (14), crushing unit (14) can carry out automatic shredding with the waste material after die-cut this moment, guarantees that follow-up waste material transports the stability and the convenience of carrying work.
