摘要： A process for production of a two-part cage nut from a single metal plate. The cage nut includes a nut slidably carried on a holding part. The nut includes a base plate having a threaded sleeve. The holding part includes a holding plate having an aperture and a pair of side walls which are bent over the edge of the base plate of the nut. The process production includes stamping the holding part and nut from a single metal plate. The nut is joined to the base plate by a narrow connecting web. The base plate is then bent about the connecting web and positioned over the holding plate between the side walls. The side walls are bent inwardly until they extend over the side edges of the base plate of the nut. The nut is separated from the holding plate by shearing off the now bent over portion of the connecting web. The nut is permitted to slide between boundary tabs on a guide path between the side walls.

摘要翻译： 用于从单个金属板制造两部分保持螺母的方法。 保持螺母包括可滑动地承载在保持部件上的螺母。 螺母包括具有螺纹套筒的基板。 保持部包括具有开口的保持板和在螺母的基板的边缘上弯曲的一对侧壁。 工艺生产包括从单个金属板冲压保持部件和螺母。 螺母通过窄的连接腹板连接到基板。 然后将基板围绕连接腹板弯曲并且定位在侧壁之间的保持板上。 侧壁向内弯曲，直到它们在螺母的底板的侧边缘上延伸。 通过剪切连接网的现在弯曲的部分，螺母与保持板分离。 螺母允许在侧壁之间的引导路径上的边界突出部之间滑动。
