Abstract
The utility model discloses a kind of location structures of the large-scale axial blade of forging, it includes forging die lower die, it is provided in the forging die lower die for the molding cavity of blank, wherein, it is located at the top of leaf in the forging die lower die and is arranged at intervals with two locating pieces 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 when the location structure forging of above-mentioned forging large size axial blade, blank is not easily moveable when forging, and worker is facilitated to put material centering, effective solution blank horizontal looseness problem.Consistency when being not only simple in structure, realization easy to process, and improving blade forging, reduces the scrappage of blade.
Description
Technical field
The utility model belongs to axial blade forging technology, more particularly, to a kind of positioning knot of the large-scale axial blade of forging
Structure.
Background technology
Large-scale axial blade on gas turbine, shape are that circle handle 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 cannot coincide with mold well, and leaf top and petiole position are easy horizontal looseness when conventional forging method forges,
Overlap is uneven, causes petiole and leaf top position when forging fold defect occur, influences final finished surplus, cause product report
It is useless.
Utility model content
The purpose of this utility model is to provide a kind of location structures of the large-scale axial blade of forging, to solve the prior art
The problem of leaf top and petiole position are easy horizontal looseness when middle forging mold forging.
For this purpose, the utility model uses following technical scheme：
A kind of location structure of the large-scale axial blade of forging comprising forging die lower die, the interior setting of the forging die lower die are useful
In to the molding cavity of blank, wherein the forging die lower die, which is located on the position on leaf top, 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.
Particularly, described two locating pieces are arranged along the length direction parallel interval of the forging die lower die.
Particularly, described two locating pieces are string configuration.
Particularly, the spacing of described two locating pieces coordinates the width of the technique lug to be arranged.
The beneficial effects of the utility model are the location structure forging of the large-scale axial blade of the forging compared with prior art
Between the technique lug of blank is put into two locating pieces of forging die when making, blank is not easily moveable when forging, and facilitates worker
Put material centering, effective solution blank horizontal looseness problem.It is not only simple in structure, realization easy to process, and improves leaf
Consistency when piece forges, reduces the scrappage of blade.
Description of the drawings
Fig. 1 is the structural representation of the location structure for the large-scale axial blade of forging that specific embodiment of the present invention provides
Figure.
In figure：
1, forging die lower die；2, blank；3, cavity；4, locating piece；5, technique lug.
Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, the positioning for the large-scale axial blade of forging that Fig. 1, which is specific embodiment of the present invention, to be provided
The structural schematic diagram of structure.
In the present embodiment, a kind of location structure of the large-scale axial blade of forging includes forging die lower die 1, the forging die lower die 1
It is inside provided with for 2 molding cavity 3 of blank, the forging die lower die 1 is located at setting on the position on leaf top, and there are two locating pieces
4, described two locating pieces 4 arrange that described two locating pieces 4 are length along the length direction parallel interval of the forging die lower die 1
Strip structure, and the width setting of the technique lug 5 of 2 end of spacing cooperation blank of described two locating pieces 4, the blank 2
The technique lug 5 of end is positioned between being stuck in described two locating pieces 4.
When die forging, between the technique lug 5 of blank 2 is put into two locating pieces 4, blank 2 can be accurately positioned, reduce base
Expect 2 horizontal looseness, is folded caused by horizontal looseness when to effectively avoid forging, reduce blade rejection rate, saved life
Cost is produced, there is practicability.
Above example is to elaborate the basic principle and characteristic of the utility model, and the utility model is not by above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, these changes
Change and change and both falls in claimed the scope of the utility model.The utility model requires protection scope is wanted by appended right
Ask book and its equivalent thereof.
