1. a forming apparatus for spring armor in spring cable, it is characterized in that it comprise receive be wound with center beam tube beam tube dish tool (51), receive be wound with the coil of wire tool (52) of spring wire (21), mould (53) that spring armor is formed;

  • Beam tube dish tool is rotatably mounted on the first fixed mount (511) by the first axle (513), and coil of wire tool is rotatably mounted on the second fixed mount (521) by the second axle (523);

    First fixed mount is fixed on ground, and the second fixed mount is fixed on ground, and the first fixed mount is parallel with the second fixed mount;

    Coil of wire tool is positioned at beam tube dish tool rear and in the stationary state, and the axis of coil of wire tool is higher than the coboundary of beam tube dish tool;

    The mould that spring armor is formed is positioned at beam tube dish tool front;

    The mould that described spring armor is formed is rectangular shape, and this mould has the center pit (532) running through left and right side, and center pit is positioned at the central authorities of left surface and right flank, center pit is cylindrical hole;

    In the outside of center pit, centrally direction, hole has shaped hole, shaped hole is made up of stretched hole (531) and the threaded hole (533) that is connected with stretched hole, and the diameter in stretched hole and the diameter of threaded hole are equally large, and stretched hole and threaded hole do not communicate with center pit;

    Described threaded hole is at least a whole spiral;
