<p>An internally-cooled big disk used in a straight-pass continuous wire-drawing machine comprises a wheel hub (18), a wheel rim (19), and a spoke (20). The spoke (20) is connected to one end of the wheel hub (18). A cooling cavity is disposed on an inner side of the spoke (20). A fixing sleeve (5) sleeves on the outer side of the other end of the wheel hub (18). A liquid input connector (7) and a liquid output connector (6) are connected to the fixing sleeve (5). The liquid input connector (7) and the liquid output connector (6) are in communication with the cooling cavity of the spoke (20) through a communication hole on the wheel hub (18). The internally-cooled big disk enables a cooling liquid to circulate in an enclosed manner and perform cooling internally; the cooling liquid does not contact a wire, and the wire does not need to be blow-dried, thereby simplifying the apparatus in an overall manner, saving energy, and improving the cooling effect, the lubricating effect, and the product quality.</p> |
