Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable core wire drawing device. Background Art

[0002] The wire drawing process is the first production process of wires and cables. Usually, the cable with a larger diameter is evenly stretched through a strong wire drawing machine, and then repeatedly drawn through multiple wheels. The cable has become a silk thread, and only after multiple stretchings does it meet the usage standards.

[0003] When optimizing the existing cable core drawing device, most of them are reflected in avoiding the friction between the wire core and the guide wheel frame when the wire core is fixedly placed at both ends of the wire core barrel. For example, the Chinese utility model patent with application number CN201922388818.6 discloses "A cable core drawing device". In this device, a workbench is provided, and wire core barrels are evenly arranged on the workbench. The bottom of the workbench is evenly connected with support columns. Fixed frames are respectively installed on the left and right sides of the workbench. A cross bar is connected between the fixed frames on the left and right sides, and the wire core barrels are installed on the cross bar. The first guide wheel is connected to a push rod at the top position between the fixed frames on the left and right sides, and the second guide wheel is installed on the push rod corresponding to the wire core barrel, and the third guide wheel is installed at the upper and lower positions on the right side of the fixed frame. A base is provided on the right side of the fixed frame, and a wire drawing die is installed on the left side of the base. A winding drum frame is provided on the base on the right side of the wire drawing die. The first guide wheel is fixed to the cross bar by a combination of a slider and a slide groove. When the metal wire core on the wire core barrel moves back and forth, the first guide wheel moves along with it, thereby avoiding friction between the fixed wire core and the guide wheel frame when the wire core is fixed at both ends of the wire core barrel.

[0004] Although the above-mentioned cable core wire drawing device has certain advantages in avoiding the friction between the wire core and the guide wheel frame when the wire core is fixedly placed at both ends of the wire core barrel, it still has certain disadvantages: the cable core needs to undergo multiple processing during the wire drawing process, and pass through wire drawing dies of various specifications to continuously refine the thickness of the wire, so the wire drawing dies need to be replaced frequently. The wire drawing dies are troublesome to disassemble, which can easily damage the entire device. Utility Model Content
