Embodiment 1

[0040] as attached Figure 1-7 As shown, a process method for processing the floating wall tiles of the flame cylinder by using ring forgings, including the steps of preparing ring-shaped finished products and cutting and forming steps, the preparation of ring-shaped finished products: machining the tile blanks to obtain ring The finished product, the size of the ring-shaped finished product is the same as the size of the cylindrical structure formed by the end-to-end connection of several tiles, and the cutting and forming is to cut the ring-shaped finished product to obtain several independent initial finished tiles.

[0041] In this embodiment, a process method for processing the floating wall tiles of the flame cylinder by using ring forgings, the floating wall tiles are prepared by first preparing the ring-shaped finished product, and then cutting the processing method, so that multiple floating wall tiles can be prepared in one process. The wall tile replaces the existin...

Embodiment 2

[0043] Such as Figure 1-7 As shown, a process method of processing the floating wall tile of the flame cylinder by using a ring forging in this embodiment is further refined on the basis of Example 1: it also includes step 1: preparing the blank of the tile: forging the blank to obtain tile blank, the tile blank is cylindrical, and the average diameter of the tile blank is the same as the average diameter of the finished tile; step 4: processing air film holes: prepare a number of channels on each initial finished tile The hole is used as the air film hole for guiding the cold air to make the finished tile; step 5: inspection and testing: inspect the processing size, roughness and cleanliness of the finished tile made in step 4 according to the requirements of the floating wall product, if the inspection result If the product does not meet the product requirements, corresponding treatment is carried out; the step of preparing a ring-shaped finished product is step 2, and the ...

Embodiment 3

[0052] Such as Figure 1-7 As shown, on the basis of Example 2, a process for processing the floating wall tiles of the flame tube by using a ring forging in this embodiment is further refined as follows: Step 2 specifically includes the following steps: Step 2.1: Rough turning: The inner circle, outer circle and both ends of the rough turning blank; Step 2.2: Finish turning: the inner circle, both ends and outer circle of the rough turning rough; Step 2.3: Finish milling: milling of the rough blank The outer circular surface is milled to form a raised part on the surface of the tile, and the raised part includes a connecting stud and / or a positioning post and / or a reinforcing rib; step 2.4: preparing a blending hole: the blank after processing in step 2.3 Prepare mixing holes for auxiliary fuel and air mixed combustion to obtain a ring-shaped finished product.

[0053]In this embodiment, a process method for processing the floating wall tiles of the flame tube by using the a...

Abstract

The invention relates to the field of aero-engines and gas turbines, in particular to a process for machining flame cylinder floating wall tile blocks by adopting annular forgings. The process comprises a step of preparing annular finished products and a step of molding by cutting; the step of preparing the annular finished products is to machine tile block blanks to prepare the annular finished products; the sizes of the annular finished products are the same with the sizes of cylindrical structures formed by connecting multiple tile blocks end to end; the step of molding by cutting is to cutthe annular finished products to prepare multiple independent tile block initial finished products, so that multiple floating wall tile blocks can be prepared through once machining flow, and the production efficiency is improved; and meanwhile, correspondingly, approximate location degrees of multiple structures on each floating wall tile block can be easily guaranteed, so that the sizes of themultiple floating wall tile blocks prepared in each process flow are the same, structure-stable floating walls are formed in the same flame cylinder, the module assembly requirements can be preferablymet, and the flame cylinders can stably work for a long time.

Description

technical field [0001] The invention relates to the fields of aeroengines and gas turbines, in particular to a process method for processing floating wall tiles of a flame cylinder by using a ring forging. Background technique [0002] The floating wall is one of the very important parts in the combustion chamber of the engine. It is generally assembled on the outer side of the inner wall of the flame tube and the inner side of the outer wall to separate the high-temperature gas from the inner and outer walls of the flame tube and form a cooling air flow between the flame tube and the floating wall. The channel reduces the temperature of the flame cylinder wall. The floating wall is generally composed of a number of floating wall tiles in the shape of an overall arc. The floating wall tiles are provided with a number of connecting studs and positioning columns. [0003] At present, in the field of aero-engines or gas turbines, in order to ensure a durable and stable connec...
