Abstract

PURPOSE: To apply spinning of high drawing threshold and good wall thickness accuracy by preceding a drawing roller having an end radius larger than that of an ironing roller and performing drawing and ironing successively.
CONSTITUTION: For a blank sheet 1 which is mounted to an inside die 2 and is rotating, a drawing roller 5 having an end radius r1 is preceded to an ironing roller 6 having an end radius r2. In this case, the radius r1 is set larger than the radius r2. Further, the preceding amount Δ of the drawing roller 5 is expressed by the difference in the contact positions with the blank sheet 1 at the foremost end in the advance direction of the respective rollers. Even if the blank sheet 1 is spinned in one pass in this way, drawing threshold and wall thickness accuracy may be considerably improved as compared with those in the prior art.
