Description
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.
