Description
Technical field
The present invention relates to forging special-shape ring manufacturing technology field, specifically a kind of manufacture method of GH3536 alloy strip flange bowl-type ring forging.
Background technology
GH3536 alloy is that iron-holder is higher and with the nickel base superalloy of chromium and molybdenum solution strengthening, anti-oxidant, corrosion resistance strong, hot and coldly shapes with welding performance better, and Long-term service temperature is below 900 DEG C, and short-term operation temperature can reach 1080 DEG C.
GH3536 alloy strip flange bowl-type ring forging is a kind of part that aviation field is conventional, and its shape is flanged (FLGD) bowl-type, and internal-and external diameter is all less, and shaping difficulty is large.The existing manufacture method of GH3536 alloy strip flange bowl-type ring forging has two kinds:
1) setting down, then obtains bowl-type ring forging by each several part welding overall;
2) machined is carried out to large wall thickness rectangle ring, after removing excess stock, obtain bowl-type ring forging.
Adopt first method, the material structure of forging and commissure, each forging material structure of segmentation manufacture all there are differences, thus have impact on the overall performance of forging; Being released in following process and use procedure of welding stress can make forging produce moderate finite deformation.
Adopt second method can destroy the streamline integrality of forging, reduce forging overall performance; Remove lot of materials simultaneously and not only cause the wasting of resources, and add process time and cost, the manufacturing cycle is long, less economical.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of manufacture method of GH3536 alloy strip flange bowl-type ring forging, adopt special loose tool monolithic molding, solve the even streamline of forging tissue odds that classical production process causes imperfect, avoid welding stress release and waste of material, reduce production cost, shorten the process-cycle, ensure that forging quality.
The technical solution used in the present invention is as follows:
A manufacture method for GH3536 alloy strip flange bowl-type ring forging, comprises following steps:
1) straight-flanked ring embryo processed
By the sawing on request of GH3536 alloy bar material, the bar that sawing is good be heated to 1140 DEG C ~ 1160 DEG C and be incubated, temperature retention time is: the effective thickness × 5min/10mm of bar, then carries out jumping-up, punching, reaming to bar, obtains straight-flanked ring embryo;
2) stairstepping ring embryo processed
Plug will be pulled out and insert straight-flanked ring embryo endoporus, and segment rectangle ring embryo is lain on lower anvil, press drives upper anvil the part ring embryo be placed on lower anvil to be applied to the pressure of 1000T ~ 3000T, manipulator rotates straight-flanked ring base simultaneously, acquisition internal diameter is constant, wall thickness reduction, outer wall is step-like special-shaped ring embryo.
Be enclosed within saddle by stairstepping ring base, saddle lies on saddle support, and on the abnormity that press drives shape face to mate with stairstepping ring base, anvil applies the pressure of 1000T ~ 2500T to stairstepping ring base, obtains internal diameter and expands, the stairstepping ring embryo of wall thickness reduction.
3) bowl-shape ring embryo is made
Stairstepping ring base is upside down on lower anvil, heavy caliber end upward, small-caliber end down, wedge shape drift is put into stairstepping ring embryo endoporus from heavy caliber end, press drives upper anvil drift to be applied to the pressure of 2000T ~ 4000T, make drift be pressed into stairstepping ring embryo bulging, obtain heavy caliber end by the bowl-type ring embryo swollen.
4) flanged bowl-type ring forging is made
Bowl-type ring base is put into shaping loose tool, shape and size in shaping loose tool and flanged bowl-type ring forging form fit, the heavy caliber end of punching pin from bowl-type ring base is put into, press drives upper anvil punching pin to be applied to the pressure of 3000T ~ 4500T, punching pin is made to be pressed into bowl-type ring embryo bulging, bowl-type ring base swells and fills shaping loose tool inner chamber, the flanged bowl-type ring forging of final acquisition.
Beneficial effect of the present invention is: 1) adopt loose tool monolithic molding, can keep the streamline integrality of forging, and appearance and size is closer to finished product, and the surplus that follow-up machined is removed greatly reduces, and improves stock utilization, shortens the process-cycle; 2) without the need to welding, ensure that the uniformity of ring forging internal material tissue, avoid the distortion because the material structure difference that causes of welding and Stress Release cause.
