Description
Technical field
The invention belongs to field of machining and machinebuilding technology, particularly ground Gas Turbine part turbine load-bearing frame.
Background technology
As shown in Figure 1, the traditional design structure of heat ray filter includes following two：
1. heat ray filter is made up of casing 1, the first housing 7, the second housing 3, the 3rd housing 6, support 5, wherein casing 1,
First housing 7, the second housing 3, the 3rd housing 6 and support 5 all adopt same high-temperature alloy material.First housing 7, the 3rd shell
Body 6 is welded on casing 1；Support 5 is welded on the 3rd housing 6；Second housing 3 is welded on the first housing 7.
2. heat ray filter is still made up of casing 1, the first housing 7, the second housing 3, the 3rd housing 6, support 5, but casing 1 is adopted
High temperature alloy forging, the first housing 7, the second housing 3, the 3rd housing 6, support 5 is used all to adopt stainless steel material.First housing 7,
3rd housing 6 is welded on casing 1；Support 5 is welded on the 3rd housing 6；Second housing 3 is welded on the first housing 7.
Heat ray filter is a requisite component in ground gas turbine turbine part turbine load-bearing frame, and enterprise exists
When developing gas turbine, it is necessary to consider that gas turbine competitiveness commercially, in the reliability for ensureing gas turbine,
In the case of long-life, the content that must take into when manufacturing cost is design structure is reduced.
The content of the invention
The technical problem to be solved in the present invention is：A kind of combustion engine heat ray filter is provided, in the reliability for ensureing gas turbine
Property, it is long-life under the premise of, start with from its structure and assemble method, reduce heat ray filter cost, reduce processing and manufacturing difficulty.
The present invention is selected from material and structure is started with, and on the one hand considers to save high temperature alloy consumption, saves high temperature alloy hair
The expense of material, on the other hand considers to improve traditional case structure, integral casing is split as two different parts of materials, then is adopted
With the connected mode of riveting, can avoid because high temperature alloy and the stainless steel welded expense brought and difficulty problem.
Technical scheme is as follows：
A kind of combustion engine heat ray filter, including casing, the casing include outer casing and switching casing, the inner circle of outer casing
Week is connected with the excircle riveting of switching casing.As former casing has a step, therefore casing is split from the step
Excircle for outer casing and switching casing, the inner periphery of outer casing and casing of transferring just is overlapped at step, is adapted to riveting.
The outer casing is high temperature alloy part, and switching casing is stainless steel part.
The outer casing is forge piece.
In the present invention, traditional monoblock type case structure is changed to outer casing and switching casing riveting form, so
The outer casing contacted with high-temperature fuel gas adopt high temperature alloy forging material, remaining spare part, including the first housing, the second housing,
3rd housing, support and switching casing etc. due to not with high-temperature fuel gas directly contact, general rustless steel sheet metal component can be adopted
Material.The inner periphery of outer casing is mutually riveted with the excircle of switching casing and is assembled into heat ray filter.Using the structure, a side
Face reduces material cost, on the other hand reduces difficulty of processing.
Compared with two kinds of traditional heat ray filter structures, the present invention has larger advantage：
1., relative to directly manufacture heat ray filter is processed using high temperature alloy forging, the substituted in present configuration
The high temperature alloy of high woollen cost is replaced by rustless steel by one housing, the second housing, the 3rd housing, the material of support, while this
Plant and replace reliability and the life-span for not affecting heat ray filter；
2., relative to being welded with stainless steel material using high temperature alloy forging, casing is split as outer casing and is turned by the present invention
The mode of casket of picking solves the problems, such as that high temperature alloy is larger with stainless steel material welding difficulty, due to high temperature alloy and rustless steel
Material welding need to be carried out under vacuum protection atmosphere, and manufacturing procedure is long, and processing and manufacturing expense is of a relatively high, therefore present invention reduces
Welding cost.
Description of the drawings
Heat ray filter schematic diagrams of the Fig. 1 for traditional structure；
Fig. 2 is heat ray filter structural representation of the present invention；
The wherein outer casing of 1. casings, 1-1., 2. 1-2 switching casings, rivet, 3. the second housing, 4. packing material, 5.
Frame, 6. the 3rd housing, 7. the first housing.
Specific embodiment
As shown in Figure 2, outer casing 1-1 adopts high temperature alloy forging as woollen.Switching casing 1-2, the first housing 7, the
Two housings 3, the first housing 7, the 3rd housing 6, support 5 adopt same stainless steel material.First housing 7, the 3rd housing 6 are welded
On switching casing 1-2, support 5 is welded on the 3rd housing 6, and the second housing 3 is welded on the first housing 7,7 He of the first housing
Packing material (adiabatic asbestos or glass fibre) is filled between 3rd housing 6.Finally using rivet 2 outer casing 1-1 and switching
Casing 1-2 connection composition heat ray filters.
Same stainless steel material welding is easier, and processing charges is low compared with the processing charges that different materials are welded；Using riveting
Nail 2 is riveted, and will not be deformed as welding like that external casing 1-1, and the form and position tolerance of the outer casing 1-1 of impact causes heat ray filter
Component need the external casing 1-1 of volume to be assembled after supplementary processing operation, so as to further save processing charges；Due in market
The buying price of upper high-temperature alloy material is 10 times of stainless steel material, if adding forging expense, high-temperature alloy material forging
It is 15～20 times of stainless steel material.And in said structure, only have outer casing 1-1 to use high temperature alloy forging woollen, other such as the
One housing 7, the second housing 3, the 3rd housing 6, switching casing 1-2 and support 5 adopt stainless steel materials, then significantly save
Material cost.
In Fig. 2 φ 1 be the excircle diameter of outer casing 1-1, φ 2 be the inner periphery diameter of switching casing 1-2, φ 3 is to turn
Pick the excircle diameter of casket 1-2, and φ 1, the size of φ 2 are by the structures shape of turbine load-bearing frame, using the outer of the present invention
Casing 1-1 and switching casing 1-2 combinative structurees, can increase the size of φ 3, as far as possible so as to reduce the forging of outer casing 1-1
Part woollen expense.So that diameter 1 is φ 450mm as an example, using 1 manufacturing expense of traditional structure in background technology 50 or so；The back of the body
2 manufacturing expense of traditional structure in scape technology is 43 or so；Using the structure manufacturing expense of the present invention 30 or so.
