The application discloses a punching device with notch trimming function for anastomat titanium nail production, and relates to the technical field of metal punching, which comprises a bending unit and an anti-abrasion unit. The bending unit comprises force applying blocks and a force receiving block, and the anti-abrasion unit comprises a rotating block and a roller. After the titanium nail is punched by a hydraulic cylinder, the titanium nail is conveyed to the bending unit. When the titanium nail is bent, the force applying blocks on both sides of the force receiving block move synchronously to the force receiving block.
