Description

A kind of titanium alloy one word countersunk nut mould
Technical field
This utility model belongs to Stamping Die Technology field, is specifically related to a kind of titanium alloy one word and sinks Head nut 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 one word countersunk nut, is with a titanium alloy slightly rod first in prior art Headstock portion and big footpath, milling flat recess the most again, finally beat a hole, the most raw-material waste pole Greatly, cost the highest, and efficiency is low, silk hole is the most eccentric, and quality is the best.
Utility model content
The purpose of this utility model is to provide a kind of titanium alloy one word countersunk nut mould, solves Certainly prior art uses turning and the method machining titanium alloy one word countersunk nut material of milling Waste problem big, ineffective.
This utility model be the technical scheme is that a kind of titanium alloy one word countersunk nut molding Mould, including the lower mold cooperated and upper mold, the upper and lower surface of through lower mold is provided with ladder Hole, the upper mold lower surface relative with lower mold is provided with staking punch;Staking punch includes being arranged on upper mold The staking punch a of lower surface, staking punch a are cylindrical shape, the affixed punching of free end of staking punch a Pressure head c, staking punch c are up big and down small round table-like, and staking punch c coaxially sets with staking punch a Putting, the free end of staking punch a is positioned at affixed two the staking punch b of lateral symmetry of staking punch c, Staking punch b is strip;The orthographic projection of two staking punch b is positioned at along the long line to centrage Diametrically, one end of two staking punch b orthographic projections is with staking punch c's in staking punch a orthographic projection Orthographic projection is connected, and the other end of two staking punch b orthographic projections is connected with the orthographic projection of staking punch a.
Feature of the present utility model also resides in:
Shoulder hole includes the first shoulder hole being arranged on lower mold lower surface and is arranged on table in lower mold Second shoulder hole in face;Second shoulder hole is divided into two parts, is connected including with the first shoulder hole Round table-like hole and the cylindrical bore that is connected with lower mold upper surface, the first shoulder hole is with round table-like The small end in hole is connected and aperture is equal;It is provided with plug in first shoulder hole.
The aperture of cylindrical bore is equal with the external diameter of staking punch a.
Staking punch a is fixed in the center position of upper mold lower surface, and shoulder hole is arranged on lower mold Center 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 one word countersunk nut, by lower mold and upper mold with the use of, utilize staking punch to titanium alloy Blank bar carries out pier system, makes head, big footpath and positioning step hole, flat recess one-shot forming, Ensure that the concentricity in a hole, substantially increase work efficiency;And the course of processing does not produces Chip, effectively saves raw material.
Accompanying drawing explanation
Fig. 1 is that the structure of this utility model a kind of titanium alloy one word countersunk nut mould is shown It is intended to;
Fig. 2 is for utilizing this utility model one titanium alloy one word countersunk nut mould punching The product sectional view become;
Fig. 3 is the left view of Fig. 2.
In figure, 1. lower mold, 2. upper mold, 3. the first shoulder hole, 4. the second shoulder hole, 5. staking punch A, 6. staking punch b, 7. staking punch c, 8. a word countersunk 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 one word countersunk nut mould, as it is shown in figure 1, bag Including the lower mold 1 and upper mold 2 cooperated, the center position of through lower mold 1 upper and lower surface sets Being equipped with shoulder hole, upper mold 2 lower surface relative with lower mold 1 is provided with staking punch;Staking punch bag Including the staking punch a5 being fixed in upper mold 2 lower surface center position, staking punch a5 is cylinder Shape, the free end affixed staking punch c7, staking punch c7 of staking punch a5 are up big and down small round platform Shape, staking punch c7 is coaxially disposed with staking punch a5, and the free end of staking punch a5 is positioned at punching press Affixed two the staking punch b6 of lateral symmetry of head c7, staking punch b6 is strip;Two punchings The orthographic projection of pressure head b6 is positioned at the diameter of staking punch a5 orthographic projection along the long line to centrage On, one end of two staking punch b6 orthographic projections is connected with the orthographic projection of staking punch c7, two punchings The other end of pressure head b6 orthographic projection is connected with the orthographic projection of staking punch a5.Staking punch a5, two Staking punch b6 and staking punch c7 is affixed is an entirety.Shoulder hole includes being arranged on lower mold 1 time First shoulder hole 3 on surface and be arranged on the second shoulder hole 4 of lower mold 1 upper surface;Second-order Ladder hole 4 is divided into two parts, including the round table-like hole being connected with the first shoulder hole 3 and and lower mold The cylindrical bore that 1 upper surface is connected, the first shoulder hole 3 is connected also with the small end in round table-like hole And aperture is equal, the aperture of cylindrical bore is equal with the external diameter of staking punch a5.First shoulder hole Plug it is provided with in 3.The material of staking punch a5, staking punch b6 and staking punch c7 is 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 shoulder hole of lower mold 1, finally make upper mold 2 vertical downward movement, profit Bring it about plastic deformation punching with staking punch to titanium alloy blank bar applying pressure to go out such as figure 2, the finished product shown in Fig. 3.The first shoulder hole 3 is utilized to form the head of a word countersunk nut 8, Utilize the second shoulder hole 4 and staking punch a5 to form the big footpath of a word countersunk nut 8, utilize punching Pressure head c7 forms the positioning step hole in a word countersunk nut 8 bigger diameter end face, utilizes staking punch b6 Form the flat recess in a word countersunk nut 8 bigger diameter end face.Lathe resets simultaneously, by the first ladder The plug pushing-off product arranged in hole 3.
