WIPO Patent Application WO/2022/109965

A1

A combined three-wire cold-drawing machine. A proximity switch A (3) is mounted on one side of the surface of a housing (1), three extension frames (4) are provided, the extension frames (4) are mounted on one side of a surface of the housing (1), an electric push rod (10) is mounted at the bottom end of an inner wall of the extension frame (4), a folding rod (8) is welded to one side of a surface of the electric push rod (10), an iron block (9) is fixedly connected to one side of a surface of the folding rod (8), an electromagnet (7) is mounted on the inner wall of the extension frame (4), a lengthening bin (11) is mounted on the surface of the housing (1), three pulling blocks (13) are provided, the pulling blocks (13) are mounted on an inner wall of the lengthening bin (11), three feeding bins (15) are provided, and the feeding bins (15) are mounted on one side of a surface of the lengthening bin (11). According to the combined three-wire cold-drawing machine, the three extension frames are used for supporting and moving a pipe drawn out by the cold-drawing machine, so that the pipe is prevented from falling due to the weight of the pipe and as such bending a product; and feeding is synchronously and automatically conducted by means of the three feeding bins, so that labour consumption is reduced, and the automation degree of the whole machine is higher.
