Abstract
The utility model discloses a prevent that die forging turbine blade profile part from filling discontented mould structure, it is including last mould and lower mould of correspond setting up, prefabricate the blank set up in go up and carry out the die forging between mould and the lower mould, wherein, the crooked position of the corresponding prefabricated blank in impression position of lower mould upwards extends there is the lower mould bellying. Above -mentioned mould structure reaches the demand that insufficient size of a dimension combines to satisfy minimum machining allowance to the position that the blade forging is sufficient, the actual thickness data of analysis blade, calculates reasonable mould thickening volume. Design mould molding and carry out manufacturing after the modification. Again, heat the blade of underfill to forging temperature, can suitably reduce the heating temperature who forges high temperature according to the calculation demand of hitting power, realized like this that the blade is local to forge the shaping, reduced the unqualified risk of performance, improved the qualification rate of reprocessing of filling discontented quality problems in the blade part.
Description
Technical field
This utility model belongs to turbine blade swaging technique, especially relates to one and prevents die forging steam turbine leaf
The mould structure that sheet profile local is not fully filled.
Background technology
Turbine blade forging part belongs to typical long-axis forging, Gu the structure of the preform of its correspondence is also
It it is major axis class.This forging is in forging process, because of the construction features of preform, at preform and mould
There occurs buckling phenomenon during tool juxtaposition metamorphose, directly results in the forging that preform crooked position is corresponding
Position is difficult to be full of, and material too much flows to the direction of bending.Although in the design process, it is contemplated that strengthen
The size of the preform of crooked position, but this phenomenon is still difficult to eliminate in actual production process.Go out
Existing this situation, normal processing scheme is by the blade of underfill in the case of vane thickness surplus abundance
Re-start heats forged, since it is desired that make the local sufficient of underfill, it is necessary to by blade integral thickness to
Thin inner forging, improves forging hitting power.Producing in reality, often occurring due to forging press
Big license hitting power limits, although adding forging times, blade can not the situation of jumping, forging office
The problem that portion is not fully filled can not get solving.If forging temperature is too high and deflection is less, blade also can be brought
Performance reduces the most underproof risk.
Utility model content
The purpose of this utility model is to provide a kind of mould preventing die forging turbine blade profile local to be not fully filled
Lamps structure, its have reduce molding hitting power, reduce forging temperature and improve conforming product rate feature, with
The problems referred to above present in turbine blade die forging process in solution prior art.
For reaching this purpose, this utility model by the following technical solutions:
A kind of preventing the mould structure that is not fully filled of die forging turbine blade profile local, it includes being correspondingly arranged
Upper die and lower die, preform is arranged between described upper die and lower die and carries out die forging, wherein, described lower mold
The crooked position of impression position correspondence preform upwardly extended lower mold lobe.
Especially, to have downwardly extended upper mold convex for the crooked position of the impression position correspondence preform of described upper mold
The portion of rising.
Especially, the thickness of described lower mold lobe is 0.5～2mm.
Especially, the thickness of described lower mold lobe is 0.5～2mm.
The beneficial effects of the utility model are, compared with prior art described in prevent die forging turbine blade profile
The mould structure that local is not fully filled, for the position of blade forging not abundance, analyzes the actual (real) thickness data of blade
And abundance size combination meet the demand of minimum machining allowance, calculate rational mould thickening amount.
Processing and manufacturing is carried out after die modeling is designed amendment.The blade of underfill is re-started and is heated to forging
Make temperature, can suitably reduce the heating-up temperature of forging high-temperature according to the calculating demand of hitting power, be achieved in that
Blade local forging molding, reduces the underproof risk of performance, improves blade local and is not fully filled quality
Problem reprocess qualification rate.
Accompanying drawing explanation
Fig. 1 is that the die forging turbine blade profile local that prevents that this utility model detailed description of the invention 1 provides is filled
The schematic diagram of discontented mould structure.
In figure:
1, upper mold；2, lower mold；3, lower mold lobe；4, upper mold lobe.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Refer to shown in Fig. 1, Fig. 1 be this utility model detailed description of the invention 1 provide prevent die forging steamer
The schematic diagram of the mould structure that machine blade profile local is not fully filled.
A kind of mould structure preventing die forging turbine blade profile local to be not fully filled includes the upper mold being correspondingly arranged
1 and lower mold 2, preform is arranged between described upper mold 1 and lower mold 2 and carries out die forging, described lower mold 2
The crooked position of impression position correspondence preform has upwardly extended lower mold lobe 3；The impression of described upper mold 1
The crooked position of position correspondence preform has downwardly extended upper mold lobe 4.
The thickness of described lower mold lobe 3 is 0.5～2mm.The thickness of described lower mold lobe 4 be 0.5～
2mm。
The above-mentioned mould structure preventing die forging turbine blade profile local to be not fully filled is not fully filled at blade forging
The impression position of region correspondence mould carries out local in the case of meeting minimum process surplus and thickeies design, this
The blade of sample not abundance is when utilizing the mould forging improved, and mould thickening position first contacts workpiece and is allowed to deform,
Substantially reduce molding hitting power.In the case of forging press hitting power meets, forging temperature can be reduced
Spend 50～100 degree, synchronize to greatly reduce the underproof risk of properties of product.This method for designing is equally applicable
In other position underfills of forging or the Resolving probiems of misrun.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by upper
Stating example to limit, on the premise of without departing from this utility model spirit and scope, this utility model is the most various
Change and change, in the range of these changes and change both fall within claimed this utility model.This practicality is new
Type claims scope and is defined by appending claims and equivalent thereof.
