The invention particularly relates to a rolling-cutting type flat cable stripping device, belonging to the technical field of cable processing equipment. At present, the strip process of the flat cable before leaving the factory chas problems that: manual stripping occupies more personnel, but the efficiency is low and the cost is high; In order to enhance the mechanical capacity of the cable, thewire rope was added into the cable and sintered together with the outer skin, which increased the difficulty of peeling. It is difficult to control the force when cutting the skin manually, and it iseasy to damage the inner thread, which causes great potential safety hazards and waste. The device comprises a high-precision pinching and length fixing device and a transverse wedge-shaped verticalcolumn type ball positioning device; Crosscutting and peeling device with two U-shaped cutters, cylindrical rolling and slitting device. The invention provides a safe, economical and convenient automatic stripping device for flat cable, which provides technical guarantee for stripping of flat cable. It can greatly improve the processing efficiency and reduce the production cost of enterprises. Thedevice has broad application prospects and significant economic and social benefits.
