Whorl boils pressure basic cycle time is very short, accordingly, the measurement in the cycle time in exercise demarcate very important. A kind modular axial whorl of the structure rolls pressure head is to be able to make whorl makes exercise simplification above all, still can carry simple operation at the same time but the diameter of the work of fine tuning treatment with special standard spirit. Whorl rolls the important core component that press fitting buy is LMT company production. With use workpiece Zhang Jin to machine work way photograph to compare, the advantage that use whorl rolls press fitting buy is treatment rate is high, manufacturing cycle is short, dimension accuracy is strong and exterior quality beautiful. The whorl of new-style Evoline axial that LMT develops rolls pressure head exterior the design is advanced, and have processability can mix high the good point with good precision (graph 1) . On the world first add the thread that has painting to roll pressure head up to now, the whorl that LMT company produces rolls pressure head to produce medium application to already had the history of 60 one's remaining years in industry. The whorl that this company produces rolls pressure head to there is axial to boil in much work treatment press type, tangent to boil press type and radial to boil control the work way that type differs a few kinds (graph 2) . Gaojusheng produces the whorl quality that uses the whorl that this company produces to roll pressure head to machine economy is good. If processes typical work has steel structure of costal region of spoke of the journal of all sorts of whorl standards, oriented pinion, bicycle, spare parts, belt wait. Still have in the user that the whorl that this company produces rolls pressure head undertake machining rolling mill of flower, breach level off of surface of tine, workpiece and workpiece are spherical level off and pipe fitting are contractible wait for treatment to work. The productivity that although whorl is used to boil in thread machining,controls fashion is highest, but before the whorl that the experts of research and development of LMT company produce to its rolls pressure head to look accessible manufacturing efficiency still dissatisfactory. This kind of manner also is reflected in this company development adds the thread that has painting to roll pressure head respect. LMT company development went on the world first to add the thread that has painting to roll pressure head, this whorl rolls pressure head and the whorl that did not add coating to roll pressure head photograph to compare, service life was lengthened 30% . In addition, research and development person the more good point that still develops whorl to roll pressure head for the user hard, pay attention to the operation advantage sex that studies whorl rolls pressure head, whorl of new-style Evoline axial rolls pressure head to be born accordingly. Of LMT company research and development this kind brand-new the mainest characteristic that the whorl of new-style Evoline axial of the design rolls pressure head, it is OK above all very the diameter that the fine tuning with accurate essence is in the treatment workpiece in roll, it is as a result of this system modular structure, so that place is installed at installing. Evoline axial whorl rolls pressure head to be able to make through corrective arbor fine tuning limits is achieved 0.

01mm, and those who have flange diameter is tall repeat accuracy, in addition, it is good that Evoline axial whorl rolls pressure head to use comfortable sex, machine program is stable. When treatment works, can ensure in same scale position of flange diameter but repeatability maintains in ± 0.

Inside the limits of 01mm. What this axial whorl rolls pressure head is modular tectonic by the whorl roller, whorl roller outer garment that contains gear change mechanism, connection that contains device of central focus device and fine tuning implement, standardization authority staff, shut device and shut off position blocking a group and authority staff composition (graph 3) . Close calorie of circle but 360 ° are rotational, such facilitating that the existing work that attends to the machine tool installs a system to undertake ideal is adjusted. Connection implement with the handle card encircled off position to ensure between lever deliver stability of the cutting tool below condition in reliable torque run without deflexion, this is special the operation demand that accords with operation personnel. For example, operation personnel but very convenient shut those who contain refrigerant device to be added as an accessory install whorl to roll press bed. Ensure this axial whorl rolls the on the safe side that machines working procedure contain in pressure head dig bits protector, the sex of on the safe side that makes process work gets promotion further. The metal of the generation in the dig bits that machines generation and workpiece prior operation is atomic won't impact whorl rolls pressure head inside, although be in connection implement when opening, dig bits and metallic particle also won't enter whorl to roll pressure head inside, this is the optimal protection of the workpiece surface of pair of plating nickel. So far, the whorl that the user uses Evoline axial whorl to roll pressure head to machine has M6~M10, M8~M16 and M12~M22 3 kinds of norms. This model the major attribute that axial whorl rolls pressure head is: Treatment is fast, simple allow with essence of life; Treatment is effective and periodic short and whorl intensity beautiful, quality is high; Whorl rolls fine tuning of diameter of pressure head flange handy and essence of life is accurate; Use modular structure, roll pressure head facilitating installation; Comfortable match a gender strong. Normally, undertake whorl rolls the significant time that approachs treatment to be in 1s. And when using whorl cutting, effective working hours should boil than whorl press tower above 5~20 times. For example, use radial whorl to boil press a method to undertake processing work, steel is cast-iron of workpiece grow the UNF 0 that is 19mm.

625in (1in=25.

4mm) the handling time of whorl is 0.

8s. And similar treatment work uses whorl cutting method to need 4.

8s. Inside such very short significant basic cycle time, circular sex whorl boils press treatment to ask to apparent distance staff guage very tall, the line is carried to go up to ask to apparent distance staff guage in workpiece very tall also. Because significant basic cycle time is short,be not just can reduce manufacturing cost significantly, whorl rolls the service life of press fitting buy to grow also is the main factor that reduces manufacturing cost. Whorl of use Evoline axial rolls pressure head to pledge for 9SMn28 material workpiece machines M20 × 1.

The whorl of 5, the service life that whorl rolls press fitting buy is treatment 250000 workpiece. Of course, if machine the intensity of workpiece to increase, so the service life that whorl rolls press fitting buy can be reduced. Roll the service life of press fitting buy to also can raise whorl when processing the work with great strength, LMT company rolled out this company research and development inside alive bound limits first add the thread that has coat to roll press fitting buy, namely Protec Power whorl rolls press fitting buy. With use did not add the thread that has coat to roll photograph of press fitting buy to compare, protec Power is machining intensity when the work with older simple capable person (intensity most greatly 1700N/mm2) , service life was lengthened 30% . Rolling the Gao Cai of whorl surface quality that presses treatment to use the fatigue strength that rolls the whorl that presses treatment is spotless, using the fatigue strength that rolls the whorl that presses exercise treatment is 3 times of the fatigue intensity of the whorl that uses piece of urgent task way to machine normally. The reason is, use the material fiber that rolled the whorl that presses exercise treatment to form all sorts of differring. Material shapes in cold substance the pressure that needs to roll press fitting buy through whorl in the process exceeds stretch limit, become plasticity from this, this is called the deformation that keeps changeless. Be in however when shaping, in working as be being machined in cutting same, material fiber was not cut off, arise however displacement and by squeezing ramming. It is on the foundation with whorl higher intensity, use whorl to boil press treatment to make a method can ensure even the security of workpiece. The rough surface protruding that uses whorl to roll the workpiece whorl that presses methodological treatment is 1~4 μ M highly between sunken peak cereal, such, the flatness of the whorl surface of the flatness of workpiece whorl surface and grinding is identical, much better even. Protecting resource respect, use whorl to roll pressure head to machine exercise to be able to make important contribution for this: Use means of this kind of thread machining to save stuff. The initiative diameter that uses whorl to roll the workpiece that controls operation is less than the thread outside diameter that treatment makes. The reason is, when material undertakes cold substance shapes, material from whorl base the department supports ministry displacement to whorl, make thread by the material of displacement, such, do not produce waste material in thread machining exercise, also do not produce an influence to machine the dig bits of exercise.
