Alloy stamping edge rolling method

The invention discloses an alloy stamping and rolling method which comprises the following steps: firstly, slitting an alloy plate with a specific width, then carrying out primary stamping and rolling on the alloy plate to obtain a primary rolling product, and after the primary stamping and rolling, preliminarily bending two ends of the alloy plate into 45-degree shapes; the two ends of the alloy plate are further bent to be 90 degrees, the middle of the alloy plate begins to be bent, the two ends of the alloy plate are close to each other, and then the third-time rolling product is subjected to fourth-time stamping rolling; the alloy plate is supported by the rolling round core, so that the alloy plate is initially round; and after the four-time edge rolling procedure is completed, stamping and shaping are conducted on the four-time edge rolling product, namely left-right shaping, up-down shaping and left-right shaping in sequence, and after the three-time shaping procedure, the roundness tolerance of the fi
