Abstract

The invention provides a novel integral turning method of blades, which can effectively solve the problem of insufficient pressing force of the blades during the assembly machining of the blades in the past and also overcome the defect of insufficient rigidity caused by interrupted cutting. The novel integral turning method of the blades is simple and can greatly enhance machining efficiency. The novel integral turning method of the blades is characterized by comprising the following steps of: positioning the blades by simulating an assembling state, and pressing the positioned blades on a turning jig by using a press plate; then pouring a low-melting-point alloy between the blades and the turning jig; disassembling the press plate after the low-melting-point alloy is cooled and solidified; firmly bonding the blades and the turning jig depending on the low-melting-point alloy so that an integral rigid part is formed by the blades and the turning jig, and then carrying out assembly machining on the blades; and after the blades are subjected to the assembly machining, placing the blades and the turning jig into hot water so that the blades and the turning jig are separated because the solid low-melting-point alloy is melted when heated, and therefore the assembly machining of the blades is completed.

Description

A kind of blade novel overall jiggering method
Technical field
The present invention relates to the blade processing technical field, be specially a kind of blade novel overall jiggering method.
Background technology
To add man-hour in combination be with pressing plate each position of blade to be compressed one by one to the cluster engine blade generally speaking, in process, dodge working position by changing pressing plate, compress blade root when compressing integral shroud, processing integral shroud when promptly processing blade root, because it is interrupted cut and discontinuous machining, so its existence compresses hypodynamic problem, and in working angles, easily produce noise, connect the not enough problems of rigidity such as tool marks and processing dimension instability.For solving the problem of above-mentioned rigidity deficiency, generally between combined blade, install timber wedge additional, be used for the support blade rigidity, but because blade profile is a three-dimension curved surface, timber wedge subtype face is difficult to processing and puts in place, can only lean on on-the-spot repair, big and sub a section of can only support in the profile of timber wedge of workman's workload does not fundamentally solve the stiff problem after blade makes up.
Summary of the invention
At the problems referred to above, the invention provides a kind of blade novel overall jiggering method, blade compressed hypodynamic problem when it can effectively solve the processing of blade combination in the past, and can solve the rigidity deficiency that causes because of interrupted cut, its method is simple, can improve working (machining) efficiency greatly.
Its technical scheme is such, it is characterized in that: be pressed on the jiggering anchor clamps with vane simulated confined state location and with pressing plate, between blade and jiggering anchor clamps, pour into a mould low-melting alloy then, treat to remove described pressing plate after the described low-melting alloy cooled and solidified, lean on described low-melting alloy with described blade and described jiggering anchor clamps secure bond, make described blade and described anchor clamps form a complete rigid member, carry out blade combination processing then; After the blade combination machines, described blade and jiggering anchor clamps are put into hot water, solid-state low-melting alloy is met heat fusing, and described blade promptly separates with the jiggering anchor clamps, finishes blade combination processing.
It is further characterized in that: described low-melting alloy is a sn-bi alloy; Metallic tin and bismuth metal shrinkage ratio are 1:1 in the described sn-bi alloy.
A kind of blade novel overall jiggering method of the present invention, it relies on low-melting alloy with blade and jiggering anchor clamps secure bond, make blade and jiggering anchor clamps form a complete rigid member, the thrust of blade and the integral rigidity in the machining when having guaranteed blade combination processing.
Description of drawings
Fig. 1 is blade and jiggering anchor clamps mounting structure schematic diagram among the present invention.
The specific embodiment
See Fig. 1, blade novel overall jiggering method of the present invention, be pressed on the jiggering anchor clamps 3 with blade 1 simulation confined state location and with pressing plate 2, between blade 1 and jiggering anchor clamps 3, pour into a mould low-melting alloy 4 then, treat to remove pressing plate 2 after low-melting alloy 4 cooled and solidified, with blade 1 and jiggering anchor clamps 3 secure bond, make blade 1 and jiggering anchor clamps 3 form a complete rigid member by low-melting alloy 4, carry out blade combination processing then.After the blade combination machines, blade 1 and jiggering anchor clamps 3 integral body are put into hot water, solid-state low-melting alloy 4 is met heat fusing, and blade 1 promptly separates with jiggering anchor clamps 3.Low-melting alloy 4 is a sn-bi alloy; The shrinkage ratio of metallic tin and bismuth metal is 1:1 in the sn-bi alloy 4, and it can guarantee that sn-bi alloy can not cause deformable blade when cooling, fusing, guarantee the blade processing quality.Among Fig. 2,5 are leak stopping mud.
