A wire rope is simultaneously machined by a breaking mechanism, a chamfering mechanism, aperforating abutting mechanism and a riveting mechanism which are sequentially arranged on the comprehensive workbench; a drag motor conveys the wire rope to the breaking station from the feeding wirecoil, a rope head is installed on a rope head mold through the automatic supply mechanism and then is conveyed to the perforating abutting station, and feeding of the wire rope and the rope head is achieved; and the wire rope on each station is clamped by a linkage pneumatic claw of the transportation mechanism, and the transportation mechanism travels to achieve material transfer and finished product discharging. The control system finishes automatic control over the process of wire rope dragging, breaking, chamfering, wire rope and rope head perforating abutting, riveting, finished productrecycling and transportation. The device is high in automation degree, simple and compact in structure and high in transportation efficiency and can automatically adapt to breaking, chamfering, perforating abutting and riveting of wire ropes of various lengths and diameters.
