    • PROBLEM TO BE SOLVED: To perform stable bending by press with less horizontal vibration while hardly affecting the function or design of a product and also without being affected by change in shear work state by press.SOLUTION: The method for manufacturing a press component 1, which includes a band plate piece 4 extended from a base end 10 to a distal end 11 and bend between the base end and the distal end and a base plate 2 cantilever-supporting the band plate piece with the distal end being a free end, includes steps of: punching a base plate by shearing work by press to form a non-bent band plate piece; partially correcting inclination on at least one main surface of both main surfaces 4a, 4b in the band plate piece to form a corrected surface 12 parallel to front and reverse surfaces 2a of the base plate; and pressing the band plate piece with a press work die to bend the band plate piece. In the bending step, the press starts from a portion where the corrected surface is formed.
    • 要解决的问题:通过冲压进行稳定的弯曲,水平振动较小,同时几乎不影响产品的功能或设计,也不受压力下剪切作业状态变化的影响。 解决方案:用于制造按压部件1的方法,其包括从基端10延伸到远端11并在基端和远端之间弯曲的带板件4和支撑悬臂的基板2 所述带板片与所述远端为自由端,包括以下步骤:通过冲压加工剪切所述基板以形成非弯曲的带状片; 部分地校正带板件中的两个主表面4a,4b的至少一个主表面的倾斜度,以形成与基板的前表面和后表面2a平行的校正表面12; 并用压力模具按压带板片以使带板件弯曲。 在弯曲步骤中,压力机从形成校正表面的部分开始。 版权所有(C)2013,JPO&INPIT
