Axial steel bar cold extrusion connecting structure
The invention discloses an axial steel bar cold extrusion connecting structure. The axial steel bar cold extrusion connecting structure comprises a connecting sleeve and a connecting steel bar which are connected into a whole through extrusion. The connecting sleeve comprises an inner sleeve body and an outer sleeve body. The inner sleeve body is of a cylindrical structure and comprises an inner sleeve boss, an inner sleeve deformation area, an inner sleeve flange and an inner sleeve cone of a conical face structure. The outer sleeve body is arranged on the outer wall of the inner sleeve body in a sleeving manner and is in zero-clearance fit with the inner sleeve body. The outer sleeve body comprises an outer sleeve cone of a conical face structure. The connecting steel bar stretches into the inner sleeve body, and the fixed steel bar end is subjected to hardening heat treatment. According to the connecting sleeve, the metal plastic deformation principle is utilized, a professional pressing riveting tool is used for pushing the outer sleeve body and the inner sleeve body to generate relative movement, the steel bar and the sleeve form a whole, clamping force is generated between the steel bars or rod pieces at the two ends, the steel bar end subjected to hardening heat treatment is suggested to be higher in hardness and higher in tensile force resistance, and the connecting strength is further improved through the arrangement of an inner sleeve wall groove.
本发明公开了一种轴向钢筋冷挤压连接结构。包括通过挤压联接为一体的联接套筒和联接钢筋,联接套筒包括内套筒和外套筒;内套筒为圆柱形筒状结构,包括内套筒凸台、内套筒变形区、内套筒法兰和锥形面结构的内套筒圆锥;外套筒套装于内套筒外壁与内套筒无间隙配合,外套筒包括锥形面结构的外套筒圆锥;联接钢筋伸入内套筒固定的钢筋端头经硬化热处理。本发明连接套筒利用金属塑性变形的原理,使用专业压铆工具推动外套与内套产生相对运动,使钢筋与套筒形成一个整体,两端钢筋或杆件之间产生夹紧力,经硬化热处理的钢筋端头建议更高的硬度更强的抗拉伸力,内套筒壁槽的设置进一步增加了联接强度。
