Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figure 2, the numerical control milling method of the stator blade of the present embodiment adopts Digit Control Machine Tool to carry out Milling Process to obtain stator blade to blank, the stator blade that the correction processing model 10 of stator blade is machined as the expectation of Digit Control Machine Tool, wherein, revising processing model 10 is the side-play amounts by determining that the benchmark processing model of stator blade produces according to the actual stator blade processing of this benchmark processing model with respect to Digit Control Machine Tool, and deducts this side-play amount and obtain with this benchmark processing model.Benchmark processing model refers to the stator blade of actual needs.
The numerical control milling method of application the present embodiment, be different from benchmark processing model owing to revising processing model 10, therefore the stator blade that, Digit Control Machine Tool processes according to correction processing model 10 is not identical with the size of the stator blade processing according to benchmark processing model.Side-play amounts that the benchmark processing model by determining stator blade produces according to the actual stator blade processing of this benchmark processing model with respect to Digit Control Machine Tool owing to revising processing model 10, and deducting this side-play amount with this benchmark processing model obtains, therefore, the stator blade that Digit Control Machine Tool processes according to correction processing model 10 more approaches benchmark processing model, that is to say, the stator blade that the stator blade that Digit Control Machine Tool processes according to correction processing model 10 more corresponds to actual needs, can reduce the workload of staff to follow-up polishing, if it is suitable that side-play amount is selected, can also make the thickness of the stator blade processing by Digit Control Machine Tool and width meet standard and without carry out manual polishing in this region.As the above analysis, the numerical control milling method of the stator blade of the present embodiment can reduce follow-up staff's labour intensity.The numerical control milling method of the present embodiment is the design a model method of size of amendment, instead of adopts Cutter Radius Compensation Method to fill into and the difference of theoretical profile.If meeting standard, the thickness of the stator blade processing by Digit Control Machine Tool and width without carry out manual polishing in this region, avoid the precision that manual polishing causes to reduce.
As shown in Figure 2, in the present embodiment, the thickness of revising in the region of processing model 10 between the first cross section 11 to the top 12 of this correction processing model 10 is less than the thickness of benchmark processing model on opposite position, wherein, the first cross section 11 and revise distance between the top 12 of processing model 10 account for this correction processing model length 9% to 19%.In figure, dotted line represents section line.
Because the thickness of revising in the region of processing model 10 between the first cross section 11 to the top 12 of this correction processing model 10 is less than the thickness of benchmark processing model on opposite position, that is to say, the thickness of the stator blade that the segment thickness that is input to the moulded dimension in Digit Control Machine Tool is less than actual needs on opposite position, like this, the thickness of the stator blade processing by Digit Control Machine Tool more approaches the thickness of the stator blade of actual needs, main cause is, process stator blade blank hardness used high, poor rigidity, in process, there is serious cutter relieving phenomenon, therefore, generally partially thick by design size finished size, but, there is rigidity difference in the blade root of stator blade and leaf top, make the relieving amount difference at stator blade each position in the longitudinal direction, therefore, can not compensate the thickness of whole stator blade.Inventor is by carrying out the data analysis in each cross section to 90 stator blades, sum up the regularity of the actual cutter relieving of stator blade, find that the first cross section 11 is larger to the relieving amount in the region between the top 12 of correction processing model 10, wherein, distance between the first cross section 11 and the top 12 of this correction processing model 10 account for revise processing model 10 length 9% to 19%, revise the equal in length of the length of processing model 10 and the stator blade of actual needs, therefore, by the thickness reduction of the correction processing model 10 in this region, the stator blade that obtains through machining and the gap of benchmark processing model are reduced, can reduce the workload of staff to follow-up polishing, if it is suitable that thickness is selected, the thickness that can also make the stator blade processing by Digit Control Machine Tool meets standard and without carry out manual polishing in this region.As the above analysis, the numerical control milling method of the stator blade of the present embodiment can reduce staff's labour intensity.Preferably, the distance between the first cross section 11 and the top 12 of this correction processing model 10 account for revise processing model 10 length 14%.In the present embodiment, the distance between the first cross section 11 and the top 12 of this correction processing model 10 is 4.5mm, and the length of revising processing model 10 and benchmark processing model is 34.1mm.
As shown in Figure 2, in the present embodiment, the thickness of revising in the region of processing model 10 between 13 to first cross sections 11, the second cross section is less than the thickness of benchmark processing model on opposite position, wherein, the first cross section 11 is being revised between the top 12 and the second cross section 13 of processing model 10, the distance between the second cross section 13 and the first cross section 11 account for this correction processing model length 21% to 31%.There is rigidity difference in blade root and leaf top that epimere has been mentioned stator blade, make the relieving amount difference at stator blade each position in the longitudinal direction, inventor is by carrying out the data analysis in each cross section to 90 stator blades, sum up the regularity of the actual cutter relieving of stator blade, find that the relieving amount in the region between 11 to second cross sections 13, the first cross section is relatively large, wherein, distance between the second cross section 13 and the first cross section 11 account for this correction processing model length 21% to 31%, but, little to the relieving amount in the region between the top 12 of correction processing model 10 with respect to the first cross section 11, and, although the relieving amount also existing in the region of simultaneously finding to arrive between the bottom 14 of revising processing model 10 in the second cross section 13, but, this relieving amount is negligible, that is to say, processing the stator blade obtaining is requirement in the second cross section to the thickness in the region between its bottom by Digit Control Machine Tool.Therefore, by revise in the region of processing model 10 between 11 to second cross sections 13, the first cross section thickness reduction, the stator blade that obtains through machining and the gap of benchmark processing model are reduced, can reduce the actuating quantity of staff to follow-up polishing, suitable if thickness is selected, the thickness that can also make the stator blade processing by Digit Control Machine Tool meets standard and without carry out manual polishing in this region.Preferably, the distance between the first cross section 11 and the second cross section 13 account for revise processing model 10 length 26%.In the present embodiment, the distance between the first cross section 11 and the second cross section 13 is 9mm, and the length of revising processing model 10 and benchmark processing model is 34.1mm.
As shown in Figure 2, in the present embodiment, with respect to benchmark processing model, the thickness on opposite position has reduced 13.7% to 14.3% of the maximum ga(u)ge (namely interior thickness) of this benchmark processing model on the cross section in corresponding the first cross section 11 to the thickness in the region of correction processing model 10 between the first cross section 11 to the top 12 of this correction processing model 10.Preferably, the thickness of the thickness (namely interior thickness) in the region of correction processing model 10 between the first cross section 11 to the top 12 of this correction processing model 10 with respect to benchmark processing model on opposite position has reduced 14% of the maximum ga(u)ge of this benchmark processing model on the cross section in corresponding the first cross section 11.The definite of above-mentioned numerical value is by inventor, the some bit data in the first cross section 11 to be rebuild, metering result shows, the first 6 to 9 of cross section 11 deviation theory profiles, therefore, the first cross section 11 both sides profile data that are positioned at of benchmark processing model all need to bias internal 0.07mm to obtain revising the thickness of processing model 10 on the first cross section 11.That is to say, revise the thickness little 0.14mm of the Thickness Ratio benchmark processing model of processing model 10 on the first cross section 11 on opposite position.Adopt on the model five-axis machine tool of above-mentioned size and process, the stator blade thicker for middle part and both sides are narrower, the stator blade machining is 1mm at the actual (real) thickness of the center in the first cross section 11, compared with actual needs the thickness 0.99mm of stator blade on opposite position thick 0.01mm, meet
profile tolerance requirement.
As shown in Figure 2, in the present embodiment, with respect to benchmark processing model, the thickness on opposite position has reduced 9.7% to 10.3% of the maximum ga(u)ge of this benchmark processing model on the cross section in corresponding the second cross section 13 to the thickness in the region of correction processing model 10 between 11 to second cross sections 13, the first cross section.Preferably, with respect to benchmark processing model, the thickness on opposite position has reduced 10% of the maximum ga(u)ge (namely interior thickness) of this benchmark processing model on the cross section in corresponding the second cross section 13 to the thickness in the region of correction processing model 10 between 11 to second cross sections 13, the first cross section.The definite of above-mentioned numerical value is by inventor, the some bit data in the second cross section 13 to be rebuild, metering result shows, the second 5 to 6 of cross section 13 deviation theory profiles, so the region between 13 to first cross sections 11, the second cross section is revised, the second cross section 13 both sides profile data that are positioned at of benchmark processing model all need to bias internal 0.05mm to obtain revising the thickness of processing model 10 on the second cross section 13.That is to say, revise the thickness little 0.1mm of the Thickness Ratio benchmark processing model of processing model 10 on the second cross section 13 on opposite position.Adopt on the model five-axis machine tool of above-mentioned size and process, the thickness in the region of the stator blade machining between 13 to first cross sections 11, the second cross section meets
profile tolerance requirement.
When with Digit Control Machine Tool processing stator blade, in the both sides of stator blade, tool marks mark is gnawed at fillet place, causes the part width of the stator blade machining to be less than than the width of the opposite position of benchmark processing model.Therefore, as shown in Figure 2, in the present embodiment, the width of revising in the region of processing model 10 between the second cross section 13 to the top 12 of this correction processing model 10 is greater than the width of benchmark processing model on opposite position.In region between the second cross section 13 to the top 12 of this stator blade to gnaw tool marks mark obvious, cause the width distortion in this region, reduced the serviceability of stator blade.By changing moulded dimension, the width by the stator blade machining in above-mentioned zone approaches the width of benchmark processing model on opposite position as much as possible, improves the serviceability of stator blade.
In the present embodiment, with respect to benchmark processing model, the width on corresponding cross section has increased 0.2% to 0.4% of the width of this benchmark processing model on the cross section in corresponding the second cross section 13 to the width in the Nei Ge cross section, region of correction processing model 10 between the second cross section 13 to the top 12 of this stator blade.Preferably, with respect to benchmark processing model, the width on corresponding cross section has increased 0.3% of the width of this benchmark processing model on the cross section in corresponding the second cross section 13 to the width in the Nei Ge cross section, region of correction processing model 10 between the second cross section 13 to the top 12 of this stator blade.For example, the second cross section 13 both sides circular arcs that are positioned at of benchmark processing model are all outwards offset to 0.03mm to obtain revising the width of processing model 10 on the second cross section 13.That is to say, the width of correction processing model 10 on the second cross section 13 be the large 0.06mm of the width on opposite position than benchmark processing model.Adopt on the model five-axis machine tool of above-mentioned size and process, the width in the region of the stator blade machining between the second 13Zhi top, cross section more meets the requirements.The stator blade that the numerical control milling method of application the present embodiment processes meets the requirements.In the present embodiment, on benchmark processing model, the cross-sectional width in corresponding the second cross section 13 of revising processing model 10 is 14.76mm.
In prior art, the process of Digit Control Machine Tool is two steps, the first step is roughing, that is to say blank is milled into stator blade shape, only this stator blade leaves allowance, that is to say, stator blade after this fine finishining is thicker and wide than the stator blade of actual needs, then carrying out fine finishining, namely the stator blade after roughing processed according to the moulded dimension of the stator blade of actual needs, without people for reserving surplus.Because Digit Control Machine Tool is in the time carrying out the direct turned blank of fine finishining the latter (without roughing), the generation in this blank process is rocked, and makes the front end of the stator blade machining have obvious shake line, has reduced serviceability.
As shown in figures 1 and 3, Digit Control Machine Tool carries out Milling Process to blank and comprises step S10, step S20 step S30, and each step is as follows:
Step S10: blank is carried out to roughing so that the part of this blank forms the roughing blade that leaves surplus with respect to correction processing model 10 on thickness and width.Roughing blade leaves 0.05mm surplus.Other parts of blank are clamped on the fixture of Digit Control Machine Tool.
Step S20: roughing blade is carried out to semifinishing so that roughing blade is stepped in the longitudinal direction to form step blades 20, bottom 21 by step blades 20 is contraction-like to the top 22 of this step blades 20, and step blades 20 leaves surplus with respect to revising processing model 10 on thickness and width.
Step S30: step blades 20 is carried out to fine finishining.
By formed step blades 20 in above-mentioned process, therefore, stator blade is successively reduced to the surplus at top by bottom, when being carried out to fine finishining, step blades 20 reduces the Milling Force at top, and the middle part of stator blade still has good rigid support, eliminate the scarce problem of beating of top fillet, avoided the chatter phenomena of stator blade front end.
As shown in figures 1 and 3, in the present embodiment, step S20 comprises step S21, wherein, step S21: carry out the first semifinishing in the region to roughing blade between the 3rd cross section 23 to the top 12 of this roughing blade so that this roughing blade forms the first semifinishing blade that leaves surplus with respect to correction processing model 10 on thickness and width, that is to say, 23 places form a step surface in the 3rd cross section, due to the reasons in structure of rose cutter, step surface is arcwall face.Distance between the 3rd cross section 23 and the top 12 of this roughing blade account for this roughing blade length 25 to 35%.Preferably, the distance between the 3rd cross section 23 and the top 12 of this roughing blade account for this roughing blade length 20%.Form step surface in above-mentioned position and can be good at avoiding chatter phenomena.The first semifinishing blade leaves 0.02mm surplus in the region between the 3rd cross section 23 to leaf top.
As shown in figures 1 and 3, in the present embodiment, step S20 also comprises step S22, wherein, step S22: carry out the second semifinishing in the region to the first semifinishing blade between the 4th cross section 24 to the top 12 of this first semifinishing blade so that this first semifinishing blade forms the second semifinishing blade that leaves surplus with respect to correction processing model 10 on thickness and width, that is to say, in the 4th cross section, 24 places form second step surface.The 4th cross section 24 and the distance at the top 12 of this first semifinishing blade account for this first semifinishing blade length 5 to 15%.Preferably, the 4th cross section 24 and the distance at the top 12 of this first semifinishing blade account for this first semifinishing blade length 10%.The second semifinishing blade leaves 0.01mm surplus in the region between the 4th cross section 24 to leaf top.
The numerical control milling method of the present embodiment is mainly used on 4 axle lathe KH63G, 4 axle lathe U2000, five-axis machine tool DMU125P, five-axis machine tool HPC630XT and five-axis machine tool C40U.
In the present embodiment, adopt flat-end cutter that blank is processed into roughing blade, adopt rose cutter that roughing blade processing is become to step blades 20, and this step blades 20 is carried out to fine finishining.Existing, the axial length of the blade region of rose cutter and flat-end cutter is 30mm, and overall length is 80mm.But, form 5 angles of heel of spending according to roughing NC cutting tool and stator blade, the spiral feed mode of every layer of 2mm ' of the degree of depth, the axial length of blade region is the rigidity that the standard sword length of 30mm has reduced flat-end cutter entirety, therefore, in the present embodiment, the axial length of the blade region of flat-end cutter is 12mm to 15mm.After the axial length of blade region shortens, improve the rigidity of flat-end cutter entirety, reduce cutter relieving and vibration and the breaking phenomenon of flat-end cutter in working angles, the amount of feeding is increased to 120mm/min by original 90mm/min simultaneously, the roughing time was down to 12 minutes by original 16 minutes, made blank carry out rough machined efficiency and had improved 30%.
Because stator blade is free form surface, fine finishining process is the process of rose cutter and blank Point contact machining, the angle forming according to rose cutter in process and blank, the position that rose cutter participates in cutting is the intersection point place of bulb and the diameter of rose cutter.The theoretical precision of blade profile depends on diameter precision and the bulb precision of alloy milling cutter, and the quality of Part Surface Roughness mainly depends on and the density degree of rose cutter around blank processing, by accurate tool setting gauge, every physical dimension rose cutter is measured to screening, selecting Probe-radius is 4.003mm to 3.997mm, radial diameter is the rose cutter of 8.005mm to 7.995mm, has ensured the uniformity of every batch of blank machining state.In addition, the axial length of the blade region of rose cutter is 12mm to 15mm, and like this, while having reduced fine finishining, the cutter relieving of rose cutter self and a bullet, improved blade profile precision and surface roughness.
In the present embodiment, rose cutter is coating milling cutter not.Because the front end of stator blade is very weak, rose cutter is sharper, and the relieving amount of blank is fewer, and coating alloy milling cutter and coating alloy milling cutter not processs to comparison, and the stator blade that coating alloy milling cutter does not process more approaches theoretical size.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
