The method comprises the following steps of firstly debugging a first-order die, drawing a plate by the first-order die after the first-order die is qualified, and punching a positioning hole in the plate, wherein the first-order die is provided with a punch for punching the positioning hole in the plate. And (3) the shape of the drawn plate meets the requirement, and the drawn plate is used for debugging the second-order die.
As shown in fig. 1, the positioning hole is a circular hole, and the positioning hole is a through hole penetrating through the plate in the thickness direction of the plate. In the second-order die, the belt grinding and positioning are a key problem during debugging, and because the shape of the trunk lid board has large fluctuation, positioning holes cannot be punched on the molded surface of the plate, so in the step S1, two process auxiliary surfaces are selected on the plate, and the first-order die punches one positioning hole on each process auxiliary surface of the plate, and the two positioning holes are arranged.
