Description

The manufacture method of 1Cr11Ni2W2MoV alloy track type mounting edge and mould
Technical field
The present invention is specifically related to a kind of manufacture method and mould of aero-engine vector tail spray 1Cr11Ni2W2MoV alloy track type mounting edge.
Background technology
1Cr11Ni2W2MoV alloy is the strong stainless steel of a kind of martensite type heat, and its mechanical properties, stress-rupture strength limit and the creep strength limit are all higher, good combination property; Mainly for the manufacture of parts such as the casing of engine, inside/outside ring, housing and mounting edges in aircraft industry.
1Cr11Ni2W2MoV alloy track type mounting edge is a kind of common part of aero-engine vector tail spray.At present, the forming manufacturing method of 1Cr11Ni2W2MoV alloy track type mounting edge has two kinds:
1) adopt drawing forming to obtain box-shaped stock, then remove clout with Linear cut and be shaped;
2) Linear cut is carried out to sheet material, oxygen welding gas cutting is shaped.
Adopt first method, cut the material removed more, the wasting of resources caused is comparatively large, does not meet the requirement of sustainable development;
Adopt second method, mounting edge thickness, highly larger time, be subject to sheet metal thickness impact, the mounting edge performance after shaping often can not meet instructions for use.
And above-mentioned two kinds of manufacture methods also exist: 1) process-cycle is long; 3), after being shaped, streamline integrality is destroyed; 3) follow-up numerical control machine processing cost is high, is unsuitable for the problems such as batch production.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of manufacture method and mould of 1Cr11Ni2W2MoV alloy track type mounting edge, adopt overall ring base, the shaping at mounting edge both ends is realized with track type particular manufacturing craft, solve existing forming manufacturing method resource utilization low, the process-cycle is long, and streamline integrality easily goes to pot, cost is high, is unsuitable for the technical problems such as batch production.
The technical solution used in the present invention is as follows:
A manufacture method for 1Cr11Ni2W2MoV alloy track type mounting edge, is characterized in that comprising following steps:
1) embryo processed
By bar sawing on request, be then preheated to 750 DEG C ± 10 DEG C with gas furnace or the electric furnace bar good to sawing and be incubated, temperature retention time is bar effective thickness × (4 ~ 6) min/10mm; And then bar is heated to 1146 DEG C ~ 1160 DEG C and is incubated, temperature retention time is bar effective thickness × (4 ~ 6) min/10mm; Under heat-retaining condition, jumping-up, punching carried out to bar, roll in advance, obtain annular ring base after finish to gauge;
2) be shaped
Be placed in by ring base between upper and lower chopping block, press applies pressure 800T ~ 2500T by upper chopping block to ring base, and under the squeezing action of upper and lower chopping block, the oval runway blank of ring embryogenesis, upper and lower two waist indents, two ends, left and right curvature increases.
3) waist shaping
By rectangle saddle through ring embryo lie on saddle support, rectangle saddle working face contacts with ring embryo indent waist, then goes up chopping block to ring embryo waist applying pressure, and under the extruding of upper chopping block and saddle, waist inner concave flattens whole; The contact position of adjustable ring embryo and rectangle saddle is to the shaping everywhere of two waists back and forth, finally makes ring embryo two waist be parallel plane;
4) end shaping
By saddle through ring embryo lie on saddle support, saddle curved working face contact with ring embryo tip inside, upper chopping block to ring embryo end applying pressure, under the extruding of upper chopping block and saddle, end contact face formation circular arc; The contact position of adjustable ring embryo and saddle is to both ends inboard locations shaping back and forth, makes both ends be approximate half-circular;
Again shape loose tool in circular arc is arranged on saddle, saddle lies on saddle support through ring embryo, the arc surface of ring embryo tip inside and interior shape loose tool agrees with, profile loose tool is arranged on outside ring embryo end, agree with the concave lower face of profile loose tool outside ring embryo end, upper chopping block applies pressure by the top surface plane of profile loose tool, and under squeezing action, ring embryo end obtains the semicircle with loose tool consistent size;
5) planar end surface
Ring embryo after shaping is lain on lower chopping block, applies pressure 800T ~ 2500T by upper chopping block, by ring embryo planar end surface to requiring height.
A kind of mould used in 1Cr11Ni2W2MoV alloy track type mounting edge manufactures, it is characterized in that: described mould is the loose tool for shaping, comprise interior shape loose tool and profile loose tool, the upper surface of interior shape loose tool is arc surface, agree with ring embryo tip inside, the lower surface of interior shape loose tool is groove, installs agree with saddle; The lower surface of profile loose tool is circular arc concave surface, agrees with outside ring embryo end, and the upper surface of profile loose tool is plane, contacts, transmission of pressure with upper chopping block.
Beneficial effect of the present invention is: 1) adopting inside and outside shape fetal membrane to carry out shaping to ring embryo, avoiding the high cost produced because customizing special-shaped saddle, and mould is simple, and highly versatile, makes shaping convenient, fast, improves forming efficiency.2) owing to adopting overall ring embryo, stock shape and part closer to, uniform wall thickness, following process surplus is little, and waste of material is few, shortens the process-cycle, reduces cost, can ensure streamline integrality, is applicable to batch production.
