The invention discloses a double-blanking device through an IC and a blanking method thereof. The device comprises a double-blanking device body, a blanking mechanism, a
material separation mechanism,a material box clamping mechanism and a material box storage mechanism. A rolling way connector, the
material separation mechanism, a material conveying roller mechanism, the material box clamping mechanism, the material box storage mechanism, a material pushing sheet motor, a mobile base, a rail transmission motor, a rail width adjustment lead screw, a pushing rail, a baffle, a material pushingsheet air cylinder, a front-back mobile
servo motor, a material pushing rail, a material pushing sheet, a straight-line module, a
servo motor with a
brake, a material clamping box air cylinder, a front-back mobile air cylinder, a straight-line guide rail, a baseplate, a material clamping box mechanism, a material box width adjustment mechanism, a material box conveying rail, a rolling-out motor, amaterial box width adjustment mechanism support and a mounting mechanism support are arranged on the double-blanking device body. According to the double-blanking device through the IC,
automatic control is completely adopted in the whole blanking process, intelligent production is achieved, a double-blanking mechanism is adopted, accordingly, the productivity is greatly improved, and the workingintensity of workers is also lowered.
