Well-known, the treatment craft of current domestic and international columnar gear still is with cutting treatment is given priority to, angrily working procedure still is use traditional gear hobbing or insert tine treatment. Recently, development of American Gleason-Pfauter company went a kind of brand-new efficient cylinder gear angrily method -- puissant blow tooth (Gleason-Pfauter company names for " Power Skiving " ) reach bed of corresponding gear cutting machine. Although method of this kind of angrily is early in tens of studying domestic and internationally somewhat before New Year, if Pfauter company had rolled out model to be the puissant machine tool blowing tooth of P630WS 1968, and the research that this side ever also had done on the foundation that in the century on our country advanced Russia studies 559 time (home says at that time for " car tine law " ) , but as a result of be confined to the condition at that time, means of this kind of angrily lies only experiment phase, do not have all the time can aborning gets applied actually. After P630WS of Gleason-Pfauter company afterwards, model was rolled out to be PF150 1985, rolled out the puissant machine tool blowing tooth of PF200 1999 again, through ceaseless innovation of a few years and development, special the development as CNC technology, the software of the puissant treatment that blow tooth that Gleason-Pfauter company development goes was to drive engineering technology of this one new angrily to be able to be in actual production more application. Gleason-Pfauter company is on the foundation of a few years of research and development and production, rolled out model to be 400PS and 600PS recently two kinds of newest puissant machine tools that blow tooth are chosen for the user, initiated use the puissant method that blow tooth to be able to machine gear diameter to amount to 700mm, modulus amounts to 8mm, the world that circumgyrate diameter amounts to 850mm the first! During exhibition of machine tool of China International of this CIMT 2013, gleason-Pfauter company introduced method of this one brand-new the puissant treatment that blow tooth to exhibit the model that angrily machines, because the manufacturing efficiency of method of this kind of angrily wants prep above,gear hobbing is mixed insert tine, especially in the gearing that current home produces, age the circumstance with the more and more application of gear falls inside, and internal gear of the puissant treatment that blow tooth has taller efficiency than inserting tine, so many domestic gear produced the treatment method with brand-new to this kind enterprise to generate strong interest, blow tine and its angrily machine tool to understand somewhat to make an user puissant to Gleason-Pfauter company, make one introduction here especially. One, the puissant treatment that blow tooth used brief introduction of principle of the puissant treatment that blow tooth to boil, the cutting means that inserts tine to be an organic whole will machine inside, outside tine cylinder gear, in angrily treatment process, angrily cutting tool is equivalent to hob be equivalent to inserting tine knife again already, its cutting means rotates continuously for workpiece and cutting tool, come to gear hobbing and union of appearance of the campaign that insert tine angrily, the comparison of the its movement way and gear hobbing, means that insert tine sees the graph is shown 1 times. Gleason-Pfauter is puissant the treatment campaign that blows tooth pursues but Yao graph is shown 2 times, cutting tool photograph has one axis angle of cut to workpiece and circle oneself axes roll to exhibit movement in order to form each with workpiece, what at the same time axial of workpiece of cutting tool edge walks along a knife to give work in order to cut is full-length. The figure of cutting tool is very as similar as the knife that insert tine. When workpiece is straight tine, when cutting tool should age for Tou; is Tou to age when workpiece, cutting tool is common make it ages continuously. The academic tooth form of cutting tool and cutting blade appearance press principle of clench the teeth to get according to the tooth form of workpiece. When processing involute tooth form, no matter cutting tool is straight tine or Tou tine, its carry the tooth form inside section plane to all be involute. The on cutting tool tooth flank contact line when the appearance of academic cutting blade of cutting tool should press cutting tool and workpiece clench the teeth is made. Accordingly, when cutting tool it is straight tine when, cutting blade is involute form; to become on the transverse plane of cutting tool cutting tool is Tou when tine, its cutting blade is involute helicoid and circumgyrate hyperboloid cross a line. When machining gear, the cutting blade of cutting tool contacts a line mediumly in process of clench the teeth locally, use when cutting tool blunt hind it is to press what blade grinds before its. Insert tine the puissant gear hobbing that blow tooth pursues 1 puissant the comparison that blows way of tine and gear hobbing, the treatment that insert tine pursues company of Gleason-Pfauter of the 2 puissant the nextpage2 of treatment motion picture that blows tooth, puissant machine tools that blow tooth uses his machine tool, cutting tool and engineering technology are the advantage of an organic whole and development goes, the important part such as the lathe bed of its machine tool, pillar used the; of gear-hobbing machine component that has gotten test and verify and its cutter spindle and workpiece main shaft used the place on the foundation that experiments in cutting to grind cut the 2nd acting main shaft that go out, tigidity is stronger the fixed position end panel that has big diameter in order to get used to the asks; uses HSK cutting tool hydraulic quick coupler of the puissant treatment that blow tooth increased tigidity and assemble and unassemble very convenient; and modular clamping apparatus is designed not only accommodative workpiece diameter range is wide, have enough tigidity and change rate is rapid, especially the application that the software of the puissant treatment that blow tooth that Gleason-Pfauter develops promoted this one new engineering technology, make Gleason-Pfauter company is being used puissant blow tine to undertake gear cutting respect gained revolutionary headway, not only be narrated before be like on process capability initiated the world the first, and its are puissant the craft that blow tooth can age inside efficient treatment with outside tine cylinder gear achieves extremely tall angrily precision, compare with the treatment that insert tine especially, its are odd finished cost is reduced apparently. Because the cutting tool of Gleason-Pfauter design gifts the puissant craft that blow tooth is unprecedented flexible change process capability and make the management of process simple, make craft of all these tine agrees with already small lot production agrees with again big batch production. The exterior graph of 600PS of the puissant machine tool that blow tooth sees Gleason-Pfauter company the graph is shown 3 times, the technical standards of 400PS and 600PS machine tool sees a table 1. Graph 3 Gleason-Pfauter is puissant 1 Gleason-Pfauter of chart of exterior of 600PS of the machine tool that blow tooth is puissant 400PS of the machine tool that blow tooth and 600PS technology standards 3, puissant the application that blows tooth pursues 4 it is puissant inside the treatment that blow tooth, the sketch map of external gear. Nextpage pursues inside the 4 puissant treatment that blow tooth, the sketch map of external gear uses gear of the clench the teeth inside the puissant treatment that blow tooth and the example of the treatment that insert tine to be as follows quite: From 3 afore-mentioned treatment example can see: Puissant the manufacturing efficiency that blows tooth is the 4-4 that inserts tine. 2 times; and machine precision, insert tine to be DIN 8 class, puissant blow tine to be DIN 7 class, if be in,for this the circumstance of same treatment precision falls, puissant the potential production efficiency that the place that blow tooth has can be the 6-8 that inserts tine times, so puissant blowing tooth is to be able to replace those who insert tine extremely treatment craft of economy, both photograph compares puissant blow tine to be: 1.
Manufacturing efficiency but times above of tower above 4-8;2.
Treatment precision can amount to DIN 7 class or taller, tooth flank surface roughness is Rz 4;3.
Identical or the cutting tool cost that processes a work is lower;4.
The machine tool covers an area of a face to accumulate fewer;5.
Odd finished cost is being shown drop; as above, although puissant blow tine to have a lot of advantages than inserting tine, but puissant blow tine to still cannot replace the treatment that insert tine completely at present, if workpiece modulus is more than 8mm or workpiece diameter,be more than 800mm and can use the treatment that insert tine only when generation is interfered between cutting tool and workpiece. The puissant all these that blow tooth ages treatment method, although be in 20 centuries 5, 60 time study domestic and internationally somewhat, but be confined to the condition at that time fails to apply in producing practice, nevertheless at that time (1962) home has investigator to predict, all these will age the method can get applied extensively certainly henceforth, although went 50 years up to now, but this one prophecy got coming true eventually. Gleason-Pfauter company passes ceaseless research of 10 years several, development went the brand-new puissant machine tool that blow tooth to throw commercial production, with respect to enough proof the company already became Gelisen the precede person of this one new engineering technology on the world. On exhibition of this international machine tool, all these that the company introduces Gelisen showpiece ages the method also caused many domestic gear to produce the interest of the enterprise. As the country indrawn gear power strides, those who believe to regard columnar gear as brand-new and efficient angrily this one puissant the law that blow tooth, regular meeting gets applied extensively in home, and the precede person that the company regards Gelisen as domain of gear science and technology, also the ten puissant machine tools blowing tooth that cent expects to Gleason-Pfauter company is developed get applied in home at an early date, the product with will give more better for user production and ceaseless effort.
