Description

A kind of titanium alloy slotted nut mould
Technical field
This utility model belongs to Stamping Die Technology field, is specifically related to a kind of titanium alloy fluting spiral shell Female mould.
Background technology
Titanium alloy fastener is parts the most frequently used in modern aerospace field, with steel part Comparing, titanium alloy fastener has that proportion is little, specific strength is high and the advantage of good corrosion resistance.Mesh Before, titanium alloy fastener many employings turning and Milling Process, and turning and Milling Process were both wasted Raw material, efficiency is the lowest, and the shaped piece of some bar portion and leading edge deformation large percentage is also The method that it is difficult with turning and milling is processed manufacturing, or the product quality manufactured The best.Such as titanium alloy slotted nut, is with a titanium alloy first headstock of slightly rod in prior art Portion's cylindrical, then milling six side, last groove milling, the most raw-material waste is very big, cost is the highest, And efficiency is low, quality is unstable.
Utility model content
The purpose of this utility model is to provide a kind of titanium alloy slotted nut mould, solves existing Have that the method machining titanium alloy slotted nut waste of material using turning and milling in technology is big, work Make inefficient problem.
This utility model be the technical scheme is that a kind of titanium alloy slotted nut shaping mould Tool, including the lower mold cooperated and upper mold, the upper and lower surface of through lower mold is provided with through hole, The upper mold lower surface relative with lower mold is provided with staking punch;Staking punch includes being arranged on upper mold following table The staking punch a in face, staking punch a are positive hexa-prism, the affixed punching press of free end of staking punch a Head c, staking punch c are up big and down small round table-like, and staking punch c is coaxially disposed with staking punch a, The free end of staking punch a is positioned at affixed two the staking punch b of lateral symmetry of staking punch c, punching press Head b is strip;The orthographic projection of two staking punch b is positioned at punching press along the long line to centrage Head c orthographic projection diametrically, one end of two staking punch b orthographic projections and the just throwing of staking punch c Even, the other end of two staking punch b orthographic projections is connected shade with the orthographic projection of staking punch a.
Feature of the present utility model also resides in:
Through hole includes the first hole being arranged on lower mold lower surface and is arranged on the of lower mold upper surface Two holes;The cross section in the second hole is regular hexagon, the circumradius of the second hole cross section and punching The circumradius of pressure head a cross section is equal;It is provided with plug in first hole.
Staking punch a is fixed in the center position of upper mold lower surface, and through hole is arranged in lower mold Heart position.
Staking punch a, staking punch b and staking punch c be material be M2The staking punch of high-speed steel.
The beneficial effects of the utility model are: use mould of the present utility model processing titanium to close Gold slotted nut, by lower mold and upper mold with the use of, utilize staking punch to titanium alloy blank Bar carries out pier system, makes six aspects and stepped hole, flat recess one-shot forming, it is ensured that stepped hole Concentricity, substantially increase work efficiency;And the course of processing does not produce chip, effectively Save raw material.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of titanium alloy slotted nut mould;
Fig. 2 is to utilize this utility model a kind of titanium alloy slotted nut mould punching to become Product schematic diagram;
Fig. 3 is the upward view of Fig. 2.
In figure, 1. lower mold, 2. upper mold, 3. the first hole, 4. the second hole, 5. staking punch a, 6. punching Pressure head b, 7. staking punch c, 8. slotted nut.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
This utility model one titanium alloy slotted nut mould, as it is shown in figure 1, include phase The lower mold 1 coordinated mutually and upper mold 2, the center position of through lower mold 1 upper and lower surface is provided with Through hole, upper mold 2 lower surface relative with lower mold 1 is connected with staking punch;Staking punch includes affixed At the staking punch a5 of upper mold 2 lower surface center position, staking punch a5 is positive hexa-prism, The free end affixed staking punch c7, staking punch c7 of staking punch a5 is up big and down small round table-like, Staking punch c7 is coaxially disposed with staking punch a5, and the free end of staking punch a5 is positioned at staking punch c7 Affixed two the staking punch b6 of lateral symmetry, staking punch b6 is strip, staking punch a5, two Individual staking punch b6 and staking punch c7 is affixed is an entirety;The orthographic projection of two staking punch b6 It is positioned at staking punch c7 orthographic projection diametrically, two staking punch b6 along the long line to centrage One end of orthographic projection is connected with the orthographic projection of staking punch c7, two staking punch b6 orthographic projections another One end is connected with the orthographic projection of staking punch a5.Through hole includes be arranged on lower mold 1 lower surface One hole 3 and be arranged on the second hole 4 of lower mold 1 upper surface;The cross section in the second hole 4 is positive six Limit shape, the circumradius of the second hole 4 cross section and the circumscribed circle of staking punch a5 cross section half Footpath is equal.It is provided with plug in first hole 3.Staking punch a5, staking punch b6 and staking punch c7 Material be M2High-speed steel.
During work, first upper mold 2 is preheated with lower mold 1, then by titanium alloy blank rod Put into after material heating in the through hole of lower mold 1, finally make upper mold 2 vertical downward movement, utilize Staking punch to titanium alloy blank bar apply pressure bring it about plastic deformation punching go out as Fig. 2, Finished product shown in Fig. 3.The second hole 4 and staking punch a5 is utilized to form six sides of slotted nut 8 Head, utilizes staking punch c7 to form the stepped hole of slotted nut 8 head, utilizes staking punch b6 Form the flat recess of slotted nut 8 head.Lathe resets simultaneously, by arrange in the first hole 3 Plug pushing-off product.
