1. shear a drawing mould, comprise materials processing passage, described materials processing passage make material continually by while shearings drawing carried out to this material process, it is characterized in that,From the direction of material movement, described processing channel comprises the inlet-side channel being positioned at front and the outlet-side channel being positioned at rear;

  • Described inlet-side channel and described outlet-side channel combine in their channel center'"'"'s angled mode of axle X-shape;

    Described processing channel comprises the cross section making the entrance side sectional area of the outlet side sectional area ratio inlet-side channel of outlet-side channel less and reduces interval, makes material at least fill up in the exit portion of outlet-side channel and be extracted thus;

    The second cross section that the opposite side that interval the first cross section comprising the side being formed in described processing channel is reduced interval and is formed in described processing channel is reduced in described cross section is reduced interval;

    From the direction perpendicular with the moving direction of material, interval is reduced in described first cross section and the second minimizing interval, cross section comprises overlapping interval, reduce between interval and the second minimizing interval, cross section in the first cross section described in this overlapping interval and have overlap, at this overlapping interval, the cross section realizing described processing channel in the both sides of processing channel is reducedIt is more than one that minimizing interval, a certain cross section in interval and the second minimizing interval, cross section is reduced in described first cross section, and another minimizing interval, cross section is bent, andFrom the moving direction of material, described more than one cross section is reduced interval to make the rear quadrate part channel cross-section mode less than front part channel cross-section tilt.
