The invention provides a manufacturing method of an automobile instrument panel transverse beam main beam and the automobile instrument panel transverse beam main beam. The manufacturing method comprises the following steps of blanking and punching: using a blanking die and a punch press to blank and punch a steel plate, and pre-blanking the steel plate into the required preset shape, so as to obtain manufactured parts A; forming: using a hydraulic press to stretch and reshape the manufactured part A which is pre-blanked into the preset shape, so as to obtain semicircular manufactured parts B; weldin: buckling any two semicircular manufactured parts B after stretch and reshape, and using welding equipment to weld, so as to obtain welded manufactured parts C; punching: after the welding is completed, using a punching die to punch the corresponding positions of the manufactured part C. The manufacturing method has the advantages that the procedure arrangement is reasonable, the problem of low processing accuracy is solved, the influence on materials is avoided, the manufacturing cost is low, the market competitiveness of a product is realized, and the output is increased.
