Description
Technical field
The invention belongs to Quick bending manufacture fields, are related to a kind of Quick bending side of 360 ° of annulus pipe parts of engine
Method.
Background technique
The structure of certain 360 ° of annulus pipe part of type aero-engine is stainless steel referring to Fig. 1 a and Fig. 1 b, material
1Cr18Ni9Ti, using the materials in the tube of φ 10*1.It is generally used for 360 ° of annulus pipe parts at present and fills rosin in lumen
Etc. materials, using bending mould use manpower manual bending.Bending strength is big, low efficiency, and due in bending process power it is equal
Even property is poor, and pipe ovality increases after will lead to bending.
The processing method of current such 360 ° of annulus pipe parts is as follows:
1. blanking: by materials in the tube using abrasive cutting-off at certain length, which can satisfy the perimeter of part after bending.
2. filling rosin: filling rosin in tube cavity, make it full of entire lumen.
3. bending: on bending mould, so that pipe is generated 360 ° of variations along die face using manpower, form annulus.
4. correction: being corrected on bending mould to pipe after bending, make it closer to the type face of mold, guarantee curved
The qualification of curved shape.
5. changing rosin: the rosin in tube cavity being melted, its outflow is made.
6. washing rosin: the rosin for remaining in inner surface of tube is carried out dissolution removal using chemical method.
7, deburring, cleaning, inspection, storage.
This kind of processing scheme is more demanding to the level of skill of operator, is being bent using bending mould to pipe
When, it is desirable that strength person strength is uniform and duration is good, and pipe ovality increases after otherwise will lead to bending；Furthermore the set is bent
Method is manpower manual bending, and bending strength is big, low efficiency.
Summary of the invention
It is an object of the invention to overcome the above-mentioned prior art, a kind of 360 ° of annulus tubings zero of engine are provided
The Quick bending method of part, this method can be realized the Quick bending of 360 ° of annulus pipe parts of engine, can be avoided artificial
Bring error is operated, reduces the manipulation strength of bending personnel, processing efficiency is higher, and processing cost is low.
In order to achieve the above objectives, the Quick bending method of 360 ° of annulus pipe parts of engine of the present invention include with
Lower step:
1) materials in the tube are cut；
2) rosin is filled in materials in the tube；
3) materials in the tube are clamped and is positioned on bending tool, then bending tool is stepped up then to pass through on the three-jaw of lathe
Lathe drives bending tool rotation；Idler wheel is installed on knife tower simultaneously, and idler wheel is bonded with materials in the tube, while making idler wheel edge
The type face of bending mould moves axially, in moving process, it is ensured that idler wheel fits in materials in the tube always, thus by materials in the tube with spiral
Shape is wound on bending tool；
4) materials in the tube are corrected on bending tool, so that materials in the tube are closely attached on the type face of bending tool, guarantee materials in the tube
Curved shape is qualified；
5) rosin in materials in the tube is removed, deburring processing then is carried out to materials in the tube, obtains 360 ° of annulus pipe parts of engine.
Materials in the tube are cut by grinding wheel in step 1).
Materials in the tube are cut according to the perimeter of 360 ° of annulus pipe parts to be prepared.
The length that the length of materials in the tube is greater than 360 ° of annulus pipe part perimeter to be prepared is 360 ° of annulus tubings zero to be prepared
The 2%-5% of part perimeter.
Rosin is filled in step 2) in materials in the tube, so that rosin is full of the inner cavity of entire materials in the tube.
During driving bending tool rotation by lathe, the revolving speed of machine tool chief axis is that 9 turns/min-11 turns/min.
Remove the concrete operations of the rosin in materials in the tube are as follows: first the rosin in materials in the tube inner cavity is melted, makes its outflow, so
Remove remaining rosin on materials in the tube inner wall again afterwards.
Remaining rosin on removal materials in the tube inner wall is dissolved using chemical method.
Idler wheel is uniformly moved axially along the type face of bending mould.
Time used in materials in the tube bending process is 3s-5s.
The invention has the following advantages:
The Quick bending method of 360 ° of annulus pipe parts of engine of the present invention is when specific operation, by what is cut
Materials in the tube are positioned on bending tool, then bending tool is stepped up then to drive bending tool rotation by lathe, together on three-jaw
When make idler wheel along bending tool type face move axially, in moving process, it is ensured that idler wheel fits in materials in the tube always, thus
So that materials in the tube are spirally wound on bending mould, to realize 360 ° of bendings of materials in the tube, avoid artificially being bent bring mistake
Poor problem changes simultaneously available man-power and is bent 360 ° of big problems of annulus pipe part bring bending personnel's manipulation strength, curved
Bent efficiency improves 1.5 times or more compared with the prior art.
