1. metal strengthens the manufacturing installation of helical bellows, it is characterized in that including along the direction of propulsion of tubing (30) through rack support seat (26,23,21) metal reinforcing that sets gradually (28) moulding push unit, tube wall spiral lay forming unit and reach the unit that rolls that cooperates with it, wherein:

  • Said metal reinforcing (28) forming unit includes the brake forming mechanism (27) of sheet metal strip and the delivery device (29) of moulding reinforcement;

    Said tube wall spiral lays has some support spirals that are used to form to lay the ring-shaped bearing side face (10) of tube wall and moulding and the backing roll of the setting that is intervally arranged in the forming unit, each backing roll is by the annular side face bearing support (1 that also is oppositely arranged at interval by axial support structure (5) location,

         6) supporting is provided with, being respectively arranged with at least two inscribe positions that the ring-shaped bearing side face (10) with required formation adapts can be by the main backing roll of actuating unit (34) driven rotary, wherein at least one is for being located by connecting in annular side face bearing support (1,6) the fixed main backing roll (3) on, another is for adjusting under the structure control can be arranged on this annular side face bearing support (1 in the radially mode of top offset/locking of said ring-shaped bearing side face (10),

         6) the movable main backing roll (4) on, at annular side face bearing support (1,6) go up through corresponding supporting structure (11) and also at least two aiding support rollers (12) are arranged on other inscribe position that the ring-shaped bearing side face (10) with required formation adapts, metal reinforcing (28) at said ring-shaped bearing side face (10) is sent into the end place, is respectively arranged with to be used for laying the sandwich layer extrusion die (32) and the outer extrusion die (33) of plastic strap to being admitted to metal reinforcing (28) surfaces externally and internally;

    The said rolling body that have milling roller (13) that be used to apply radial pressure of unit that roll for being provided with at the outside and the corresponding position of at least one said backing roll of said ring-shaped bearing side face (10) through rack support seat (21).
