Rod piece connecting system and connecting method thereof
The invention discloses a rod piece connecting system and a connecting method thereof. The connecting system comprises a sleeve for connecting rod pieces and a special anvil for extruding the sleeve to realize fixed connection between the sleeve and the rod pieces; and the connecting method adopts a rivet pressing mechanism to drive the special anvil to axially extrude the sleeve to realize shrinkage riveting connection of the sleeve. The connecting system uses a metal plastic deformation principle, uses an extrusion mounting tool for extruding the sleeve in the axis direction of the sleeve to shrink the outer diameter of the sleeve; sleeve metal flows into a gap between a steel bar transverse rib and a transverse rib in the radial direction, or the sleeve clamps the rod pieces, so that a certain tensile strength is achieved between the rod pieces; steel bars or the rod pieces and the sleeve form a whole with a certain tensile strength; the extrusion connecting mode of the sleeve and the steel bars or the rod pieces guarantees the consistency and the stability of the connecting strength of all joints, so that the joint performance defects caused by manual operation are prevented, the connection is firmer, and the strength is higher; and such machining as heading, peeling and thread rolling is not needed, so that the speed is fast, and the mounting efficiency is high.
本发明公开了一种杆件连接系统及其连接方法。连接系统包括用于连接杆件的套筒和挤压套筒实现套筒与杆件固结连接的专用铁砧；连接方法采用压铆机构驱动专用铁砧轴向挤压套筒实现套筒收缩铆接连接。本发明连接系统利用金属塑性变形的原理，使用挤压安装工具，沿套筒轴线方向挤压套筒，使套筒外径收缩，套筒金属沿径向方向流入钢筋横肋与横肋之间的间隙或套筒夹紧杆件，使杆件之间具有一定的抗拉强度，钢筋或杆件与套筒形成一个具有一定抗拉强度的整体；套筒与钢筋或杆件的挤压连接方式保证了每个接头连接强度的一致性、稳定性，避免了因人为操作造成的接头性能缺陷，连接更加牢固，强度更高；无需墩粗、剥皮、滚丝等加工，速度快，安装效率高。
