[0019] The features and advantages of the present invention are described in detail below with reference to the accompanying drawings.
[0020] Since the production process of the present invention is aimed at the twisting production of alloy ropes with very small monofilament diameters and rope diameters, in order to avoid the occurrence of wire breakage when the machine is stopped and restarted in an emergency during the twisting process, it is necessary to use the current steel wire rope closing machine. Increase the constant tension control device in the middle. refer to figure 1 Shown is a schematic structural diagram of the cradle device of the rope closing machine in the wire rope production process of the present invention. The cradle device includes a swing rod 18, the lower end of which is fixed to the bracket of the cradle device through a rotating shaft 185, and the swing rod 18 is installed through the shaft 183. There is a first wire pulley 181; a second wire pu...
