Automobile drawing die parallel manufacturing debugging method and production line

The invention discloses an automobile drawing die parallel manufacturing debugging method and a production line. According to the method, a plurality of corresponding first balance blocks are respectively assembled on an upper die and a lower die; first-stage die assembly is performed on the upper die and the lower die; during the first-stage die assembly, the height of the first balance block sand the inclination of the opposite surfaces of the first balance blocks are adjusted according to a distance between the upper die and the lower die; a plurality of corresponding second balance blocksare assembled on the upper die and a material pressing face correspondingly; second-stage die assembly is performed on the upper die and the lower die; and during the second-stage die assembly, the height of the second balance blocks and the inclination of the opposite faces of the second balance blocks are adjusted according to a distance between the material pressing face and the upper die. By means of the above technic
