The invention relates to a method for adjusting the relative orientation between the inner shape of a drawing part and the fiber orientation of a sheet, and belongs to the field of sheet metal stamping. According to the actual drawing production situation, the location of the highest cracking risk is determined, and a particle is transformed into a cracking point A; two straight lines B1 and B2 are separately drawn from the cracking point A to enable the straight lines B1 and B2 to be perpendicular to tangent lines D1 and D2 of material receiving lines C1 and C2; a straight line E is drawn through the cracking point to ensure that the two angles theta 1 and theta 2 of the straight line and the two tangent lines D are the same; and the straight line E is the fiber direction matched with theinner shape of a product, and the fiber direction is realized by adjusting the blanking angle of a blanking cutter relative to the sheet. The method for adjusting the relative orientation between theinner shape of the drawing part and the fiber orientation of the sheet has the advantages that the possibility of cracking at the highest cracking risk position of a drawing product is reduced, the situation is similar to the ''barrel effect'', the situation is equivalent to that on the whole, the possibility of cracking at all the cracking points of the product is adjusted in an equalizing mode,the production stability of products is improved, and the scrap rate of the products caused by drawing and cracking is effectively reduced.
