Description
Technical field
The utility model is related to forging mold field, more particularly to a kind of positioner of turbine blade blank.
Background technology
Turbine blade is structurally characterized in that blade profile is distorted, and blade root and integral shroud angle are big, thickness drop is big, and especially steam passage is long
Big blade of the degree more than 1 meter.The big blade blank of steam turbine is longer, during base, at the positioning lug and integral shroud at blank blade root
Position lug axiality and keep poor, and then need to repair the positioning table of mould according to the quality of blank lug axiality, however,
The positioning table of existing mold is monolithic construction, and the amount of repairing a die is larger when it is corrected, and repairs a die extremely inefficient；In addition, for using high
Energy fly press forging, due to hitting power greatly, soon, impulsive force is big for blow speed, and blank is easy to occur the shifting of front and rear and left and right
It is dynamic, and because blank blade root is big, integral shroud is small, is contacted during forging prior to blade root, this is easy for causing blank integral shroud to upwarp, so as to make
Into locating bias, cause the generation for forging winged phenomenon；Thus, it is badly in need of solving.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, provide a kind of positioner of turbine blade blank, with
Solve during the positioning table amendment of existing blade forging mould the amount of repairing a die big, the problem of the inefficiency that repairs a die, and the forging of existing blade
Easily there is the problem of blank forging flies in modeling tool.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of positioner of turbine blade blank, including the positioner body being arranged on forging die, the positioning
Device body includes setting on one end end face in the locating slot for being provided with v-shaped structure on positioning table, the positioning table, the locating slot
It is provided with neck, the neck to be connected with the other end end face being equipped with blank lug, locating slot and is taken for positioning blank
The tight lock part for locking blank lug is provided with the locating piece of son, the upper mould of the forging die.
As a kind of preferred scheme of the present utility model, pad is provided with the neck.
As a kind of preferred scheme of the present utility model, inclined portion is provided with the upper mould, the tight lock part is matched somebody with somebody with inclined portion
Conjunction forms on projection, the lower mould of the forging die and is provided with the groove being engaged with projection.
As a kind of preferred scheme of the present utility model, the locating piece includes clamping section and positioning section, the positioning section
Lower surface and the bottom surface of neck fit, the upper surface and the lower surface of blank lug of positioning section fit.
The beneficial effects of the utility model are that a kind of positioning device structure of turbine blade blank is simple, it is easy to
Realize, without being repaired to positioning table in its forging process, only need to change different locating pieces as needed, greatly reduce
Workload, saves the time of repairing a die, and is locked blank lug by tight lock part, can effectively prevent forging from flying, reduce forging report
Useless rate.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.It can manage
Solution, embodiment described herein is used only for explaining the utility model, rather than limits of the present utility model.
It refer to shown in Fig. 1 to Fig. 3, Fig. 1 is a kind of structure of the positioner of turbine blade blank of the utility model
Schematic diagram；Fig. 2 is the upper die structure schematic diagram of the utility model forging die；Fig. 3 illustrates for the lower die structure of the utility model forging die
Figure.
In the present embodiment, a kind of positioner of turbine blade blank, including it is arranged at the positioning at forging die integral shroud
Device body, the positioner body includes the locating slot that v-shaped structure is provided with positioning table 3, the positioning table 3, described fixed
It is provided with the other end end face being provided with one end end face in the groove of position in blank lug 5, locating slot in neck, the neck
The locating piece 4 for positioning blank lug 5 is connected with, the locating piece 4 includes clamping section 11 and positioning section 10, the positioning section
10 lower surface and the bottom surface of neck fit, and the upper surface and the lower surface of blank lug 5 of positioning section 10 fit, the forging
The tight lock part 8 for locking blank lug 5 is provided with the upper mould 1 of mould, and inclined portion 9, the tight lock part 8 are provided with upper mould 1
Cooperatively formed with inclined portion 9 and be provided with the groove 7 being engaged with projection 6 on projection 6, the lower mould 2 of the forging die.
Wherein, pad can be set in neck, and then the height of locating piece 4 can be adjusted, its universal performance is improved, certainly,
The utility model can also customize the locating piece of respective thickness according to actual needs, to adapt to different blade blanks.
Although it is noted that in the present embodiment, positioner body is arranged at the integral shroud of forging die, this practicality
Not limited to this, positioner body also may be disposed at the blade root of forging die, to carry out positioning lock to the blank lug at blade root
Tightly, and for the longer blade blank of length, positioner body need to be respectively provided with integral shroud, two positions of blade root, it is same to improve
Axle degree.
Above example is to elaborate general principle of the present utility model and characteristic, and the utility model is not by above-mentioned implementation
Example limitation, on the premise of the utility model spirit and scope are not departed from, the utility model also has various change and change, these
