The present invention relates to a coil winding drum that expands and extends in the inner winding portion of a coil to wind or unwind a coil product in a cold rolling mill of a steel mill. More specifically, the coil is expanded and contracted outside the sleeve shaft during drum operation. The present invention relates to a segment disassembly and assembly apparatus for a coil winding drum, which is capable of being easily disassembled and assembled in a state in which four segments are fixed at the same time during repair of a segment of a drum that is closely adhered or spaced to a winding part.

In general, a cold mill in a steel mill, in particular, in a plating process, a drum is provided in a pay off reel for releasing a coil and a tension reel for winding a coil, and in the sleeve shaft of such a drum. Four segmented segments are assembled to expand and contract with the forward and backward movements of the sleeve shaft and to be inserted into the inner ring of the coil to carry out the loading, winding and unwinding of the coil. Since the contraction operation is repeated, a periodic disassembly operation for removing foreign matters attached to the coil is required, and FIG. 1 illustrates a segment disassembly operation of such a sleeve shaft.
