[0002] In the existing aluminum can production process, the raw aluminum material needs to be formed by stamping equipment to make aluminum cups. The forming of the aluminum cup is completed by the punch, upper notch, lower notch, and pressing die. The process sequence is that the pressing die and the lower notch plane are closed to press the aluminum material, the cutting step is completed by the cutting edge of the upper notch and the lower notch, and then the punch and the lower notch are used to complete the extrusion forming to make the cup.

[0003] Because the stamping equipment runs continuously at high speed (200SPM), the shearing edges of the upper and lower shears require high precision (≤0.02mm). If there is a deviation, it will cause quality defects such as powdering, wire forming, and wrinkling of the aluminum shears, which will affect the normal production of the next process.
