Abstract
The utility model discloses a drawing die of a large-scale waveguide tube. An inner cavity is composed of an approach cone, a sizing belt and an exit cone in arc connection; the caliber of the approach cone is greater than that of the sizing belt; the caliber of the exit cone is gradually increased from the sizing belt; and the approach cone is composed of three stages of cone openings of which the conical degrees are orderly reduced. The waveguide tube manufactured by the drawing die is high in dimensional accuracy, and smooth in surface; and a large center part does not sink in the waist, and stress relief at a port is small.
Description
Technical field
The utility model relates to waveguide, particularly a kind of drawing die of big specification waveguide.
Background technology
As shown in Figure 1, the inner chamber of the drawing die of existing big specification waveguide is by approach cone 1, fixed through being with 2 and go out prostomum 3 and be connected in turn.Because the tapering that this approach cone is 1 whole section is consistent; Make the fixed of this drawing die through too concentrated with the distortion of approach cone 1 with 2; Thereby the pressure on the unit are increases; Frictional resistance between waveguide and the mould increases, so four jiaos of the inner surface of waveguide scratch easily, fineness is not high.And the single deflection of this mould can not be excessive, and plastic deformation is just insufficient, thereby tensile strength is low, and stress distribution is inhomogeneous, and otch is owing to Stress Release, and sectional dimension exceeds standard.
Summary of the invention
The utility model technical problem to be solved is not enough to prior art, provide a kind of can make produce that big specification wave guide cross-section size does not exceed standard, dimensional discrepancy is little, smooth surface, drawing die that tensile strength is high.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of drawing die of big specification waveguide; Its inner chamber is by approach cone, fixed through band and go out prostomum and link to each other through circular arc successively and form; And the bore of approach cone is greater than fixed bore through band, and the bore that goes out prostomum is increased by the beginning of fixed warp band gradually, and this approach cone is made up of three grades of awl mouths that tapering reduces successively.
Compared with prior art; The beneficial effect that the utility model had is: the tapering everywhere of the approach cone of existing waveguide drawing die is consistent; And the utility model approach cone is made up of three grades of awl mouths that tapering reduces successively, thereby the concentrated distortion of mould is dispersed, and has changed the distribution of frictional resistance; Because after the frictional resistance on four jiaos in the waveguide disperseed, four jiaos of situation about scratching were able to solve.Simultaneously, so also improved the single deflection of waveguide, the increase of deflection can make plastic deformation more abundant, and internal stress is more evenly distributed, thereby can make the change in size of sawing section little, and dimensional accuracy is high.The utility model because it belongs to the cold work hardening material, increases its deflection if be used for the 3A21 aluminum alloy material, and tensile strength also is improved.
Description of drawings
Fig. 1 is the structural representation of existing big specification waveguide drawing die.
Fig. 2 is the utility model structural representation.
The specific embodiment
As shown in Figure 2, the utility model is a kind of drawing die of big specification waveguide.Its inner chamber is by approach cone 1, fixed through being with 2 and go out prostomum 3 and link to each other through circular arc successively and form, and wherein three grades of awls being reduced successively by tapering of this approach cone 1 mouthfuls 11,12,13 form.
Claims (1)
1. the drawing die of a big specification waveguide; Its inner chamber is by approach cone, fixed through band and go out prostomum and link to each other through circular arc successively and form; And the bore of approach cone is greater than fixed bore through band; The bore that goes out prostomum is increased by the beginning of fixed warp band gradually, it is characterized in that, this approach cone is made up of three grades of awl mouths that tapering reduces successively.
