1. , a kind of method of making axil flow filter may further comprise the steps:

  • the raw material thin plate of preparing compacting arc ripple;

    Prepare the pressing mold that one side has the arc ripple;

    Described raw material plate is fixed on the arc inner edge of described pressing mold.Curved and the relative pressing mold of described raw material plate is tilted;

    The fixed blade of the trench engagement of energy and arc corrugated surface when preparing one group of decline;

    Described blade is moved, described raw material plate is made the shape ripple along the continuous backfin of described arc corrugated surface towards described arc corrugated surface;

    At first press down near of arc inner edge in the described blade.Then other blade presses down successively continuously.Described raw material thin plate is the fan-shaped thin plate of being made by the material of making in filtering, its both sides are curved, two straight line side spacings are dwindled gradually in addition, and one of them arc limit is fixed on described pressing mold mouth, and the inventive features of said method is;

    further comprising the steps of;

    the preparation of filter material;

    One side has the preparation of the pressing mold of arc ripple;

    The curved edge that one end of described raw material thin plate is fixed on described pressing mold makes the curved and whole raw material plate of fixed end of described raw material plate and the arc ripple face tilt of described pressing mold;

    Described blade is promoted towards described arc corrugated surface, make its fixed end of approaching described raw material plate at first contact with raw material plate, thereby the raw material thin plate is suppressed the shape corrugated sheet along described arc corrugated surface;

    The arc inner edge of described arc-shaped wave card is fixed on the center rod;

    One counter brace is fixed on the arc outer rim of described arc-shaped wave card;

    Making counter brace center on center rod towards described center rod pushing described counter brace becomes a circle and described arc-shaped wave card is pressed into circle between counter brace and center rod.
