Abstract

The invention relates to a manufacturing method for C-shaped section ring forge pieces made from Haynes 188 alloy. The manufacturing method comprises the steps of blank making, material distribution and pre-rolling, rolling forming and the like. The manufacturing method has the beneficial effects that the axial fluidity of an alloy material can be improved by increasing the forging temperature in the upsetting and punching procedures, so that the uniformity of blank deformation and material structures is ensured and blanks are prevented from cracking; the ring blanks are transferred to two ends through the step of material distribution and pre-rolling, so that the special-shaped ring blanks are closer to the target forge pieces and the middle thin wall can be rolled more easily; the rolling forming difficulty is lowered, the manufacturing efficiency is improved and the rejection rate is greatly decreased.

Description

The manufacture method of Haynes188 alloy C tee section ring forging
Technical field
The present invention relates to a kind of manufacture method of Haynes188 alloy C tee section ring forging.
Background technology
Haynes188 belongs to cobalt-based high-temperature alloy, at high temperature has excellent corrosion resistance, and the C tee section ring forging adopting Haynes188 alloy to make is that the one of aerospace field commonly uses special-shaped forge parts.At present, the manufacture of Haynes188 alloy C tee section ring forging mainly adopts free forging process, but due to the inherent characteristic of alloy material, adopts prior art to there will be ring embryo and is out of shape uneven and phenomenon that is cracking everywhere; Meanwhile, ring embryo is also not easily processed into required form, causes the defective or material structure performance of forging ' s block dimension not reach requirement.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of manufacture method of Haynes188 alloy C tee section ring forging, stock is avoided to ftracture by the forging temperature in controlled working, simultaneously in the stage of rolling in advance to stock sub-material, solve the technical problem of existing Haynes188 alloy C tee section ring forging manufacturing technology not easily embryo processed and shaping.
The technical solution used in the present invention is as follows:
A manufacture method for Haynes188 alloy C tee section ring forging, comprises the following steps:
1) embryo processed
Under the temperature conditions of 1190 DEG C ~ 1210 DEG C, sawing, jumping-up, punching are carried out to bar, obtained straight-flanked ring embryo; In punch process, punch diameter≤1/4 biscuit diameter.
2) sub-material is rolled in advance
Under the forging temperature of 1140 DEG C ~ 1160 DEG C, straight-flanked ring embryo is placed on looping mill rolling on roll mill, by rolling particular manufacturing craft in advance, straight-flanked ring embryo is processed into inwall evagination, the special-shaped ring embryo of outer wall indent, ring germ wall cross section is intermediate thin, the approximate hourglass shape that two ends are thick.
3) roll forming
Under the forging temperature of 1140 DEG C ~ 1160 DEG C, special-shaped ring embryo is placed on looping mill rolling on roll mill, by finish to gauge particular manufacturing craft, the middle part thin-walled of special-shaped ring embryo is concaved, ring germ wall cross section is c-shaped, obtains final C tee section ring forging.
Beneficial effect of the present invention is: the forging temperature of lifting jumping-up, punching operation can improve the axial flow of alloy material, thus ensures the uniformity of stock distortion, material structure, prevents stock from ftractureing; Rolled in advance by sub-material, ring embryo stock is shifted to two ends, thus makes special-shaped ring embryo closer to target forging, make the easier rolling of middle thin-walled, reduce roll forming difficulty, improve manufacture efficiency, percent defective reduces greatly.
Accompanying drawing explanation
Below accompanying drawing of the present invention is described further:
Fig. 1 is straight-flanked ring embryo schematic diagram;
Fig. 2 is the special-shaped ring embryo schematic diagram of approximate hourglass shape;
Fig. 3 is C tee section ring forging schematic diagram.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
A manufacture method for Haynes188 alloy C tee section ring forging, comprises the following steps:
1) embryo processed
Forging temperature is promoted to 1190 DEG C ~ 1210 DEG C, under this temperature conditions, sawing, jumping-up and punching are carried out to bar, obtained straight-flanked ring embryo 1, at high temperature the mobility of alloy material improves, and structural homogenity and the distortion of therefore obtained ring embryo 1 are all more even; In punch process, select the drift of diameter≤1/4 biscuit, can ftracture by anti-stop ring embryo 1.
2) sub-material is rolled in advance
Forging temperature is down to 1140 DEG C ~ 1160 DEG C to ensure the structure property of alloy material, under this temperature conditions, straight-flanked ring embryo 1 is placed on roll mill and carries out looping mill rolling, by rolling particular manufacturing craft in advance, straight-flanked ring embryo 1 is processed into inwall 2 evagination, the special-shaped ring embryo 4 of outer wall 3 indent, ring germ wall cross section is intermediate thin, the approximate hourglass shape that two ends are thick, is convenient to the shaping of follow-up C tee section.
3) roll forming
Keep the forging temperature of 1140 DEG C ~ 1160 DEG C, special-shaped ring embryo 4 is placed on looping mill rolling on roll mill, by finish to gauge particular manufacturing craft, the middle part thin-walled of special-shaped ring embryo 4 is concaved, ring germ wall cross section is c-shaped, obtains final C tee section ring forging 5.
Above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of embodiment of the present invention technical scheme.
