The present invention relates to a steel bar coupling apparatus, which allows more accurate performance of procedures from supplying to cutting and coupling by using an interlocking means moving in a longitudinal direction with rotation of a main shaft and allows more stable incoming and outgoing of a guider leading coupling wires, thereby securing stability in driving the apparatus. A steel bar coupling apparatus, in which a coupling work part formed in one side of a main body supplies coupling wires, and a coupling head installed in one side of the coupling work part cuts the coupling wires to be coupled, includes: a main shaft unit, which has a main shaft installed in such a manner that the main shaft can rotate in the longitudinal direction from a point of driving of supplying coupling wires and to a point where a coupling header is installed, and an interlocking means assembled with a main shaft moving along the longitudinal direction of the main shaft in order to sequentially perform supplying and cutting of coupling wires and coupling of steel bars; a sequential driving part, which is arranged outside the main shaft to deliver driving force for performing supplying and coupling of the coupling wires by sequential assembling with the interlocking means moving in the longitudinal direction of the main shaft; a coupling wire supplying part assembled with the sequential driving part in such a manner that the driving force can be delivered to supply the coupling wires to the coupling work part; and a coupling head driving part, which is assembled with the main shaft and the coupling head in such a manner that the driving force can be delivered and, when the interlocking means moving in the longitudinal direction of the main shaft is assembled therewith, delivers the driving force for performing cutting and twisting of the coupling wires by rotating the coupling head. |
