Description
Technical field
The present invention relates to forging mold field more particularly to a kind of positioning devices of turbine blade blank.
Background technique
Turbine blade is structurally characterized in that blade profile distorts, blade root and integral shroud angle greatly, thickness drop it is big, especially steam passage is long
Degree is greater than 1 meter of big blade.The big blade blank of steam turbine is longer, when base, at the positioning lug and integral shroud at blank blade root
It positions lug concentricity and keeps poor, and then need the positioning table of the quality finishing mold according to blank lug concentricity, however,
The positioning table of existing mold is monolithic construction, and the amount of repairing a die is larger when correcting, and the efficiency that repairs a die is extremely low；In addition, for using high
Energy fly press forging, since hitting power is big, blow speed is fast, and impact force is big, and blank is easy to happen front and back and left and right and moves
Dynamic, and since blank blade root is big, integral shroud is small, and when forging contacts prior to blade root, this is easy for that blank integral shroud is caused to upwarp, to make
At locating bias, lead to the generation for forging winged phenomenon；It is badly in need of solving as a result,.
Summary of the invention
It is an object of the invention in view of the above-mentioned problems, a kind of positioning device of turbine blade blank is provided, to solve
The problem of amount of repairing a die is big when the positioning table amendment of existing blade forging mold, the inefficiency that repairs a die and existing blade forging mould
Easily there is the winged problem of blank forging in tool.
The purpose of the present invention is be achieved through the following technical solutions:
A kind of positioning device of turbine blade blank, including the positioning device ontology being set on forging die, the positioning
Device noumenon includes positioning table, and the locating slot of v-shaped structure is provided on the positioning table, is set on one end end face in the locating slot
It is equipped with blank lug, card slot is provided in the other end face in locating slot, is connected in the card slot and is taken for positioning blank
The locating piece of son is provided with the tight lock part for locking blank lug in the upper mold of the forging die.
As a preferred solution of the present invention, gasket is provided in the card slot.
As a preferred solution of the present invention, inclined portion is provided in the upper mold, the tight lock part and inclined portion cooperate shape
At convex block, the groove matched with convex block is provided in the lower die of the forging die.
As a preferred solution of the present invention, the locating piece includes being clamped section and positioning section, under the positioning section
End face and the bottom surface of card slot fit, and the upper surface of positioning section and the lower end surface of blank lug fit.
Beneficial effects of the present invention are that a kind of positioning device structure of turbine blade blank is simple, it is easy to accomplish,
Without being modified to positioning table in its forging process, different locating pieces only need to be replaced as needed, greatly reduces work
Amount, saves the time that repairs a die, and lock blank lug by tight lock part, and forging can be effectively prevent to fly, reduce forging scrappage.

Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.It is understood that
It is that embodiment described herein is used only for explaining the present invention rather than limiting the invention.
It please refers to shown in Fig. 1 to Fig. 3, Fig. 1 is a kind of structural representation of the positioning device of turbine blade blank of the present invention
Figure；Fig. 2 is the upper die structure schematic diagram of forging die of the present invention；Fig. 3 is the lower die structure schematic diagram of forging die of the present invention.
In this present embodiment, a kind of positioning device of turbine blade blank, including the positioning being set at forging die integral shroud
Device noumenon, the positioning device ontology include positioning table 3, and the locating slot of v-shaped structure is provided on the positioning table 3, described fixed
It is provided with blank lug 5 on one end end face in the slot of position, is provided with card slot in the other end face in locating slot, in the card slot
It is connected with the locating piece 4 for positioning blank lug 5, the locating piece 4 includes clamping section 11 and positioning section 10, the positioning section
10 lower end surface and the bottom surface of card slot fit, and the upper surface of positioning section 10 and the lower end surface of blank lug 5 fit, the forging
It is provided with the tight lock part 8 for locking blank lug 5 in the upper mold 1 of mould, and is provided with inclined portion 9 in upper mold 1, the tight lock part 8
Convex block 6 is cooperatively formed with inclined portion 9, the groove 7 matched with convex block 6 is provided in the lower die 2 of the forging die.
Wherein, settable gasket in card slot, and then the height of adjustable locating piece 4, improve its universal performance, certainly,
The present invention can also customize the locating piece of respective thickness according to actual needs, to adapt to different blade blanks.
Although this is practical it is noted that positioning device ontology is set at the integral shroud of forging die in the present embodiment
Without being limited thereto, positioning device ontology 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 blade blank longer for length, it need to be respectively provided with positioning device ontology at two integral shroud, blade root positions, it is same to improve
Axis degree.
The above embodiments only describe the basic principles and characteristics of the invention, and the present invention is not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the invention also has various changes and changes, and these changes and changes are all fallen
