Abstract
The present invention relates to a kind of anti-deformation processing method of elongated bend pipe mould tire, comprise the following steps：1）Five are previously set on woollen and adds block；2）Mill adds the upper and lower surface of block, and the depth of parallelism for adding block upper and lower surface is 0.1；3）Roughing woollen upper end type face；4）Turn-over, another type face of roughing woollen；5）Annealing；6）Block is added in smoothing；7）Again block will be added at five to be positioned on the pressing plate of Digit Control Machine Tool, Roughing and fine machining type face, draws part edge line and add line of cut；8）Turn-over, which retightens, adds block, and is positioned by datum hole, Roughing and fine machining another side type face, draws part edge line and adds line of cut；9）Wire cutting is carried out to adding block；10）Repaiied and ground except the mould fetalism face added at block using model, until the type face measured using measuring machine is qualified.This method effectively solves the problems, such as the yielding accuracy of manufacture that can not be processed, ensure that elongated bend pipe mould tire of mould tire, so as to ensure that the machining accuracy of part.
Description
Technical field
The present invention relates to a kind of anti-deformation processing method of elongated bend pipe mould tire, belong to the anti-deformation processing method of bend pipe.
Background technology
At present, in aircraft manufacturing field, the required precision more and more higher of part, therefore the required precision to frock also just more
Height, and the structure of elongated bend pipe mould tire of the present invention is more special, the mould tire slender construction, it is very easy to become during processing
Shape, and can not be repaired once deforming, it can only scrap, therefore it is extremely difficult to process such fetal membrane.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of anti-deformation processing method of elongated bend pipe mould tire, this method has
Effect solves the problems, such as the yielding accuracy of manufacture that can not be processed, ensure that elongated bend pipe mould tire of mould tire, so as to ensure that zero
The machining accuracy of part.
To solve problem above, concrete technical scheme of the invention is as follows：A kind of anti-deformation processing of elongated bend pipe mould tire
Method, comprise the following steps：
1）Woollen under flame cutting machine is used on plate, while is previously set five on woollen and adds block, wherein two
It is individual that there is the side for being distributed in elongated part positioned at the both ends of woollen, the other three；
2）Mill adds the upper and lower surface of block, and the depth of parallelism for adding block upper and lower surface is 0.1；
3）Overall woollen is placed on the pressing plate of Digit Control Machine Tool, and adds block by five and is fixed, roughing hair
Expect upper end type face, stay 3mm surpluses, and in two ends machining benchmark hole；
4）Turn-over, add block again by five and be fixed, positioned by the datum hole of processing, roughing woollen is another
Type face, stay 3mm surpluses；
5）Annealing：650 DEG C are heated in stove, insulation is gradually cooling to room temperature after 30 minutes, remove caused by machining deformation
Residual stress；
6）Block is added in smoothing：Repeat step 2）, guarantee is each to add block upper and lower surface respectively at grade, the depth of parallelism
0.1；
7）Again block will be added at five to be positioned on the pressing plate of Digit Control Machine Tool, first roughing surplus 1mm, then more than semifinishing
0.3mm is measured, last finishing drum face, part edge line is drawn and adds line of cut everywhere；
8）Turn-over is fixed with pressing plate and adds block again, and is positioned by datum hole, first roughing surplus 1mm, then half finishing
Spare time measures 0.3mm, last finishing drum face, draws part edge line and adds line of cut everywhere；
9）Line of cut is added according to what numerical control marked, wire cutting is carried out to adding block；
10）The model consistent with the mould tire sectional curvature for adding block correspondence position is made, repaiies to grind to remove using model and adds
Mould fetalism face at block, until the type face measured using measuring machine is qualified, processing is completed in mark.
The anti-deformation processing method of the elongated bend pipe mould tire, which effectively solves the problems, such as that frock is yielding, to process, and protect
The accuracy of manufacture of elongated bend pipe mould tire is demonstrate,proved, so as to ensure that the machining accuracy of part.
Brief description of the drawings
Fig. 1 is the schematic diagram that elongated bend pipe mould tire is applied on bent pipe parts.
Fig. 2 is that elongated bend pipe mould mold has the structural representation after adding block.
Fig. 3 is three type face model structural representations for adding block position.
Wherein, Fig. 1 is elongated bend pipe mould tire；2 be bent pipe parts；3rd, it is to add block.
Embodiment
The anti-deformation processing method of elongated bend pipe mould tire as shown in Figure 1 is processed, is comprised the following steps：
1）Woollen under flame cutting machine, unilateral 5~7mm of made allowance are used on plate, while is previously set on woollen
Five are added block, and two of which is located at the both ends of woollen, and the other three has the side for being distributed in elongated part, as shown in Figure 2；
2）Mill adds the upper and lower surface of block, when to add the depth of parallelism of block upper and lower surface be 0.1；
3）Overall woollen is placed on the pressing plate of Digit Control Machine Tool, and adds block by five and is fixed, roughing hair
Expect upper end type face, stay 3mm surpluses, and in two ends machining benchmark hole；
4）Turn-over, add block again by five and be fixed, positioned by the datum hole of processing, roughing woollen is another
Type face, stay 3mm surpluses；
5）Annealing：650 DEG C are heated in stove, insulation is gradually cooling to room temperature after 30 minutes, remove caused by machining deformation
Residual stress；
6）Block is added in smoothing：Repeat step 2）, guarantee is each to add block upper and lower surface respectively at grade, the depth of parallelism
0.1；
7）Again block will be added at five to be positioned on the pressing plate of Digit Control Machine Tool, first roughing surplus 1mm, then more than semifinishing
0.3mm is measured, last finishing drum face, part edge line is drawn and adds line of cut everywhere；
8）Turn-over is fixed with pressing plate and adds block again, and is positioned by datum hole, first roughing surplus 1mm, then half finishing
Spare time measures 0.3mm, last finishing drum face, draws part edge line and adds line of cut everywhere；
9）Line of cut is added according to what numerical control marked, wire cutting is carried out to adding block；
10) model consistent with adding the mould tire sectional curvature of block correspondence position is made, as shown in figure 3, being repaiied using model
Grind except the mould fetalism face added at block, until the type face measured using measuring machine is qualified, processing is completed in mark.
