    摘要： Provided are a method and apparatus for manufacturing hot press formed parts for a multi-step process, the method comprising: a heating step for heating a strip material; a transferring step for transferring the heated strip material to a processing apparatus having mounted on a press a plurality of molds comprising a notching mold and/or a blanking mold, a forming mold, and a trimming mold; a notching step, for obtaining a notched material connected to the strip by means of a web portion by cutting a part of the material by means of the notching mold, and/or a blanking step for obtaining a blanked material separated from the strip by cutting a part of the material by means of the blanking mold; a forming step of transferring and positioning the material which has gone through the notching step and/or the blanking step near the forming mold, and then forming the material by means of the forming mold; and a trimming step for removing, by means of the trimming mold, an outer edge portion of the material which is unnecessary for a final product shape.

    摘要： This structural member (W1) is manufactured using a structural member manufacturing device including: a first clamping part (10) having a first lower clamping member (11) and a second upper clamping member (12) disposed to face each other and capable of being opened and closed; a second clamping part (20) having a third lower clamping member (21) and a fourth upper clamping member (22) disposed to face each other corresponding to the first lower clamping member (11) and the second upper clamping member (12) and capable of being opened and closed; and clamping part driving means for allowing the first clamping part (10) and the second clamping part (20) to be relatively separated from each other while causing a position in an X-axis direction and a position in a Z-axis direction to correspond to each other. That is, the structural member (W1) is manufactured by a structural member manufacturing method in which the first clamping part (10) and the second clamping part (20) are relatively separated from each other by the clamping part driving means.
