Axial steel bar cold extrusion connecting sleeve and special tool thereof
The invention discloses an axial steel bar cold extrusion connecting sleeve. The axial steel bar cold extrusion connecting sleeve comprises an inner sleeve and an outer sleeve, wherein the inner sleeve is of a cylindrical structure, an inner sleeve boss is arranged in the middle of the inner sleeve, the caliber of the inner sleeve boss is smaller than the inner diameter of the inner sleeve, the inner sleeve boss is used for fixing and limiting connecting steel bars at the two ends, the two ends of the inner sleeve boss are inner sleeve deformation areas where the connecting steel bars are embedded and connected, an inner sleeve flange of a flange structure is arranged on the peripheral surface of the cylindrical structure, and an inner sleeve cone is arranged at the end of the cylindrical structure; the outer sleeve is arranged on the outer wall of the inner sleeve in a sleeving mode and is in zero-clearance fit with the inner sleeve, and an outer sleeve cone is arranged at one end of the outer sleeve; and a plurality of sets of inner sleeve wall grooves are formed in the sleeve wall of the inner sleeve in the axial direction, so that a multi-section structure with the central symmetry of the radial section of the inner sleeve is formed. According to the connecting sleeve, the steel bars and the sleeve form a whole through an extrusion tool, the connecting strength is further improved through the arrangement of the inner sleeve wall grooves, the connecting machining is more stable and convenient, the connection is more accurate through the arrangement of the inner sleeve boss, and human errors during the connecting operation are avoided.
本发明公开了一种轴向钢筋冷挤压连接套筒。包括内套筒和外套筒,内套筒为圆柱形筒状结构,内套筒中部有口径小于内套筒内径用于固定限位两端联接钢筋的内套筒凸台,内套筒凸台两端是联接钢筋嵌入联接的内套筒变形区,圆柱形筒状结构外周表面设置法兰结构的内套筒法兰,圆柱形筒状结构的端部设置内套筒圆锥;外套筒套装于内套筒外壁与内套筒无间隙配合,外套筒一端设置外套筒圆锥;内套筒筒壁上沿轴向设置多组内套筒壁槽、构成内套筒径向截面中心对称的多瓣结构。本发明连接套筒通过挤压工具使钢筋与套筒形成一个整体,内套筒壁槽的设置进一步增加了联接强度,连接加工更稳定方便,内套筒凸台的设置使联接更准确,避免联接作业时的人为失误。
