The utility model discloses a slotted riveted steel strip, which has a U type steel belt. The edge of the U type steel belt is raised to the outer side to form a flange, and the flange is provided with a slot on the flange. The grooves are rectangular grooves or cross shaped inclined grooves. The vertex of the cross shaped groove in each group is symmetrically set, and the symmetrical interval between the two edges of the flange corresponding to the cross shaped groove forms a triangular protruding platform, and its upper interval forms a rhombus protruding platform. With this steel strip, the machining efficiency, riveting efficiency and the riveting quality are greatly improved and the flange is set up to prevent the steel strip from disengaging in the vertical direction of the aluminum rail, improving the processing efficiency and reducing the requirements of the riveting precision, setting the groove, and further preventing the steel strip from sliding along the longitudinal direction of the aluminum rail, that is, sliding along the direction of the line. The two wing edges of the aluminum rail are riveted in the slot, which makes the steel strip riveted more firmly with the aluminum rail body, reaching and exceeding the technical parameters required by the existing composite rail.

本技术属于钢铝复合轨
,具体涉及一种钢铝复合轨用新型钢带。
技术介绍
接触轨是沿着电气化铁路运行轨布置并将电力输送给机车的刚性输电导轨,现有的钢铝复合接触轨,从不锈钢钢带与铝轨本体的复合方式,主要分为钢铝共挤,双L型钢带在线焊接和钢带预先加工成排孔后,半冲铆等复合方式。然而,现有的不锈钢钢带与铝轨本体的复合方式存在:铆接孔加工效率低下,后期铆接工艺复杂,定位精度要求高,复合不牢靠,易出现铆销对不准钢带孔的现象,从而造成不锈钢钢带容易从铝轨本体内脱出的缺陷。
技术实现思路
本技术解决了现有技术的不足,提供一种复合牢固的钢铝复合轨用新型钢带。本技术所采用的技术方案是:一种钢铝复合轨用新型钢带,具有U型钢带,所述U型钢带两侧臂边缘加工成为向外侧凸起形成凸缘,所述凸缘上间隔开设有槽。有选的,所述槽为矩形槽或交叉形的斜槽。更有选的,相邻每组所述交叉形的斜槽顶点对称设置,与该交叉形的斜槽对应的凸缘两边缘上对称间隔形成三角形凸台,其上间隔形成菱形凸台。相较于现有技术,本技术具有的有益效果:采用该钢带,极大的提高加工效率、铆接效率及铆接质量,设置凸缘,防止钢带在顺铝轨本体垂直线路防线脱离,提高加工效率及降低铆接精度要求,设置槽,进一步防止钢带在铝轨本体内沿纵向滑动,即沿线路滑动,而且将铝轨本体两翼边铆接在该槽里,使得钢带与铝轨本体铆接的更加牢固。附图说明图1是本技术结构示意图一;图2是本技术结构示意图二;图3是图2B处局部放大示意图。具体实施方式下面结合附图和具体实施方式对本技术进行详细说明。一种钢铝复合轨用新型钢带,请参阅图1及图2,具有U型钢带 ...
