Sleeve-rolling reducing extrusion steel bar straight thread connecting piece, connecting device and connecting method
The invention discloses a sleeve-rolling reducing extrusion steel bar straight thread connecting piece, device and method, the connecting piece comprises a cylinder body and a steel bar to be connected, the inner wall of the cylinder body is provided with a plurality of rhombic tooth structures formed by cross matching of left-hand threads and right-hand threads, and the rhombic tooth structures can be tightly engaged with steel bar wire heads to be connected; the connecting device comprises a fixed table, a sleeving and stripping die assembly, a movable table and a supporting die assembly, the sleeving and stripping die assembly comprises two sets of half sleeve bodies capable of being oppositely combined, and the sleeving and stripping die assembly is embedded in a groove of the fixed table and annularly extrudes the barrel; the supporting die assembly comprises two sets of arc-shaped hoop bodies capable of being combined oppositely, the two sets of arc-shaped hoop bodies surround the outer side of a reinforcing steel bar, a limiting arc section is arranged at one end of each arc-shaped hoop body, the arc-shaped hoop bodies are located in a clamping groove of the movable table, and the limiting arc sections are arranged at the ends, close to the sleeving and stripping die assembly, of the arc-shaped hoop bodies. The reinforcing steel bar connecting device is convenient to use, and the reinforcing steel bar connecting precision and quality can be improved.
本发明公开了套撸缩径挤压钢筋直螺纹连接件、连接装置及连接方法，连接件包括筒体及待连钢筋，筒体的内壁有左旋螺纹与右旋螺纹交叉配合形成的多个菱形齿牙结构，菱形齿牙结构可与待连接的钢筋丝头密实咬合；连接装置包括固定台、套撸模组件、活动台及支撑模组件，套撸模组件包括两组可对合的半套体，套撸模组件嵌入在固定台的凹槽内并环形挤压筒体；活动台相对固定台远近移动，支撑模组件包括两组可对合的弧形箍体，两组弧形箍体环抱在钢筋的外侧，弧形箍体的一端设有限位弧段，弧形箍体位于活动台的卡槽内，限位弧段设在弧形箍体靠近套撸模组件的一端，限位弧段的端部与筒体的一端抵接限位，本发明使用方便，可以提高钢筋连接精度和质量。
