    • PROBLEM TO BE SOLVED: To ensure screw fastening force in a structure for fastening a stepped screw 110 to a thin plate material 114 of a fastened material 102.SOLUTION: In a stepped screw fastening structure to a metal thin plate material 114, half blanking parts 141-144 are formed in the thin plate material 114 in a blanking manner so as to alternately have a concave-convex shape in a circle radial manner from the center of a through hole 115, and a screw part 113 is formed by tap processing to the through hole 115 provided at a substantially central position of a blanking processing shape, and thereby a fastened part 102 is fastened to the thin plate material 114 with a screw.
    • 要解决的问题:确保用于将阶梯螺钉110紧固到紧固材料102的薄板材料114的结构中的螺钉紧固力。解决方案:在对金属薄板材料114的阶梯螺钉紧固结构中,半冲切部件 141-144以钝化方式形成在薄板材料114中,以便从通孔115的中心以圆周的方式交替地具有凹凸形状,并且通过丝锥加工形成螺纹部113 设置在冲切加工形状的大致中央位置处的通孔115,从而将紧固部102用螺钉紧固到薄板材料114上。

    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a backing plate for a drum brake reducing the number of components of the drum brake, and having a cable guide part higher than the limit height of a conventional cable guide part while ensuring the strength. SOLUTION: A thickness reduction part formed by cut-bending is divided into a center part in the longitudinal direction of a part 64a of a disk member 64 in a first press step P2, and a part located on the outer side of the center part in the longitudinal direction cut and bent by the first press step P2 out of a part 64a of the disk member 64 in the second press step P3. Thereby, since the thickness of a cable guide part 18d after the cut-bending is increased in comparison with that of a cable guide part formed by one conventional cut-bending, the limit height of the cable guide part 18d of the embodiment can be increased in comparison with the limit height of the conventional cable guide part while ensuring the strength.

    • 要解决的问题:提供一种用于制造用于鼓式制动器的背板的方法,其减少鼓式制动器的部件数量,并且具有高于常规电缆引导部件的极限高度的电缆引导部件,同时确保 力量。 解决方案:通过弯曲形成的厚度减小部分在第一压制步骤P2中被划分成盘构件64的部分64a的纵向方向上的中心部分,并且位于 在第二按压步骤P3中,通过第一按压步骤P2从圆盘构件64的部分64a切割并弯曲纵向方向的中心部分。 因此,由于与通过一次切割弯曲形成的缆索引导部相比,切断弯曲后的缆索引导部18d的厚度增加,所以能够提高本实施方式的缆索引导部18d的极限高度 与传统电缆引导部件的极限高度相比,同时确保强度。 版权所有(C)2011,JPO&INPIT
