[0002] A blanking die is to place the untrimmed and unformed material into a die with a specific-shaped cutting hole and blank it into the required shape;

[0003] A Chinese patent with the publication number of CN213617130U discloses a blanking die, which includes an upper die assembly and a lower die assembly. The upper die assembly is correspondingly arranged above the lower die assembly; the upper die assembly includes a punch main body, and the lower die assembly includes a die main body. A cutting groove adapted to the punch main body is opened on the die main body; through the guiding column on the upper die assembly and the limiting hole on the lower die assembly, the traveling direction of the blanking die is corrected and guided before the punch main body contacts the cutting groove; by arranging a second guiding part and an arc surface on the punch main body, the position of the end of the sleeve is corrected and the end of the sleeve is guided to be aligned with the cutting surface; while realizing blanking of multiple sleeves at the same time, the accuracy and stability of blanking are ensured, the damage of the die is avoided, the service life of the die is prolonged, and it is more practical.

[0004] The cutting edge of the blanking die of the above patent is exposed outside. If the staff makes an operation error during the blanking process, the falling cutting edge may cause a safety hazard. Content of the Utility Model

[0005] The purpose of the utility model is to provide a blanking die for a horseshoe-shaped automatic grinding block.
