Abstract
The invention discloses a kind of location structure for forging large-scale axial blade, it includes mould under forging die, the die cavity for being molded to blank is provided with the forging die in mould, wherein, it is arranged at intervals with two locating pieces under the forging die on mould at the top of the leaf on position, the technique lug of the blank end is positioned between being stuck in described two locating pieces.Between the technique lug of blank is put into two locating pieces of forging die during the location structure forging of the above-mentioned large-scale axial blade of forging, blank is not easily moveable during forging, and facilitates worker to put material centering, effectively solves the problems, such as blank horizontal looseness.Uniformity when being not only simple in structure, realization easy to process, and improving blade forging, reduce the scrappage of blade.
Description
Technical field
The invention belongs to axial blade FMT, more particularly, to a kind of location structure for forging large-scale axial blade.
Background technology
Large-scale axial blade on gas turbine, is shaped as justifying handle and adds blade profile to form, and length of blade reaches 1300mm, leaf
Intermediate between handle and blade profile is bigger, and the preform of the blade diameter at intermediate is far longer than other positions,
Preform can not coincide with mould well, leaf top and the easy horizontal looseness in petiole position when conventional forging method forges,
Overlap is uneven, causes petiole and leaf top position during forging fold defect occur, influences final finished surplus, cause product report
It is useless.
The content of the invention
It is an object of the invention to provide a kind of location structure for forging large-scale axial blade, to solve to forge in the prior art
Leaf top and the problem of the easy horizontal looseness in petiole position during modeling tool forging.
To use following technical scheme up to this purpose, the present invention：
A kind of location structure for forging large-scale axial blade, it includes mould under forging die, and use is provided with mould under the forging die
In the die cavity being molded to blank, wherein, mould, which is located on the position on leaf top, under the forging die is arranged at intervals with two locating pieces, described
The technique lug of blank end is positioned between being stuck in described two locating pieces.
Especially, length direction parallel interval of described two locating pieces along mould under the forging die is arranged.
Especially, described two locating pieces are string configuration.
Especially, the spacing of described two locating pieces coordinates the width of the technique lug to set.
Beneficial effects of the present invention are, compared with prior art during the location structure forging of the large-scale axial blade of forging
Between the technique lug of blank is put into two locating pieces of forging die, blank is not easily moveable during forging, and facilitates worker to put material
Centering, effectively solves the problems, such as blank horizontal looseness.It is not only simple in structure, realization easy to process, and improves blade forging
Uniformity when making, reduce the scrappage of blade.
Brief description of the drawings
Fig. 1 is the structural representation of the location structure for the large-scale axial blade of forging that the specific embodiment of the invention provides.
In figure：
1st, mould under forging die；2nd, blank；3rd, die cavity；4th, locating piece；5th, technique lug.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1, Fig. 1 is the location structure for the large-scale axial blade of forging that the specific embodiment of the invention provides
Structural representation.
In the present embodiment, a kind of location structure for forging large-scale axial blade includes mould 1 under forging die, mould 1 under the forging die
Inside it is provided with the die cavity 3 for being molded to blank 2, mould 1, which is located on the position on leaf top, under the forging die is provided with two locating pieces
4, length direction parallel interval of described two locating pieces 4 along mould 1 under the forging die arranges that described two locating pieces 4 are length
Strip structure, and the spacing of described two locating pieces 4 coordinates the width of the technique lug 5 of the end of blank 2 to set, the blank 2
The technique lug 5 of end is positioned between being stuck in described two locating pieces 4.
During die forging, between the technique lug 5 of blank 2 is put into two locating pieces 4, blank 2 can be accurately positioned, reduces base
Expect 2 horizontal looseness, so as to be folded when effectively avoiding forging caused by horizontal looseness, reduce blade rejection rate, saved life
Cost is produced, there is practicality.
Above example is to elaborate the general principle and characteristic of the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
