Description
Technical field
The invention belongs to aero-engine spare part fixture for heat treatment technical field, and in particular to one kind is used for thin-walled
Contain the frock clamp of casing heat treatment outside titanium alloy.
Background technology
Contain case structure outside certain type aero-engine sufficiently complex, be by front and rear installation while, install in the middle of 4 while, 5 it is outer
Cover cylinder, 4 longitudinally mounted sides and 15 mounting seats are formed by argon arc welding.After the completion of welding, the aero-engine
In outer culvert casing comprising 10 circular welds, 4 longitudinal seams, 16 stands circular weld, weld seam overall length exceedes 30 meters (wherein
Cylinder girth joint exceedes 22 meters), thus stress is very big after welding, cylinder part wall is relatively thin in addition, typically only 1.2mm, and in cylinder
On body in addition at mounting seat position, milling groove is also nearly all provided with, and barrel wall is thinner at milling groove, only 0.65mm, this is just
So that whole cylinder rigidity is also poor.The outer culvert casing must be heat-treated after having welded, if directly being carried out hot place
Reason, the stress formed after welding will freely discharge, and make each part that radial deformation to occur, it is impossible to coaxial between guarantee installation side
Degree, gently then can not meet final matching requirements, it is necessary to carry out maintenance process, extend the manufacturing cycle, increase production cost, it is heavy then
Just may directly scrap, waste should be formed, manufacturing schedule is delayed again.
