The specific embodiment

As Fig. 1, shown in Figure 2, the utility model is mainly by motor 1, support 2, ordinary gear 3, center duplicate gear 4 is 5, three universal joints 6 of Norton gear of 120 °, knife rest 7, cutterhead lid 9, cutterhead 12, cutter shaft 13, bearing 14, roll 15, core print 16, core bar 17, carriage 18, bin 19, waterpipe 20, boss 21, induction heating circle 22 is formed; Motor 1 connects by ordinary gear 3 with center duplicate gear 4, the Norton gear 5 that is 120 ° connects by three universal joints 6 with asterism cutter shaft 13, be contained on the knife rest 7 by bearing 14 and cutter shaft 13 two that roll 15 connects, core print 16 connects by carriage 18 with support 2, and boss 21 is integral with support 2.

The operation principle of the utility model equipment is to drive ordinary gear 3 by motor 1, pass center duplicate gear 4 by ordinary gear 3 with torque again, by duplicate gear 4 torque is passed former cutting again and be 120 ° Norton gear 5 on straight, because Norton gear 5 is connected with three universal joints 6, and three universal joints 6 connect three asterism cutter shafts 13 respectively, thereby drive the cutter shaft 13 that is contained on knife rest 7 two, and then the roll 15 that drives on the cutter shaft 13 is realized rolling, meanwhile adopt knob 8 to adjust Samsung unit and cut the diameter that directly can process different size, induction heating circle 22 is installed in the Samsung unit heart that hits, connect heating in medium frequency, make the base pipe reach the purpose of continuously and smoothly's heating rolling.

Motor 1 drives ordinary gear 3 in Fig. 1, pass center duplicate gear 4 by ordinary gear 3 with torque again, by duplicate gear 4 torque is passed former cutting again and be 120 ° Norton gear 5 on straight, because Norton gear 5 is connected with three universal joints 6, and three universal joints 6 connect three asterism cutter shafts 13 respectively, thereby drive the cutter shaft 13 that is contained on knife rest 7 two, and then the roll 15 that drives on the cutter shaft 13 is realized rolling.Core print 16 external diameters are taper, endoporus water flowing cooling, and it comes in the operation of rolling inside the Pass the control and typing chi sheet hole shape and size to use.Earlier core print 16 being connected core bar 17 feedings before rolling can be rolling for resetting on the holder that is contained in carriage 18 in the rolling pipe.In rolling, adopt bin 19 as carriage 18 guiding turnover.

Fig. 2 is an asterism advance and retreat knife structure cutaway view, support 2 is the fixed bodies that are used for finishing rolling different size element in Fig. 2, on establish three hole shapes be 120 ° parallel, cooperate with cutterhead 12, knob 8 screws in the internal thread hole of cutterhead 12 by screw mandrel, by cutterhead lid 9 knob 8 is fixed on the support 2, it can not be gone here and there up and down, shake knob 8 and adjust the unit of three cutterheads and cut the purpose that straight size reaches the levelling of advance and retreat cutter and then reaches processed finned tube level external diameter of pipe size thereby push down cutterhead 12.

Fig. 3 is Samsung transmission principle figure.

Fig. 4 is cutterhead form figure, and cutterhead about 12 is equipped with bearing 14 and supports cutter shaft 13 in Fig. 4, roll 15 is housed to realize stablizing rolling on the cutter shaft 13.

Fig. 5 is the levelling form figure of helical angle, the levelling form of helical angle is to calculate helical angle according to rolling spiral distance and diameter in Fig. 5, directly measure by flat datum level 10 with universal protractor, come turn knife rest 7 according to measurement result, distinguish immovable supports 7 with screw 11, thereby reach the purpose of the specific helical angle of roll forming.

Cooling of the present utility model mainly is to come respectively the enforcement cooling of three rolls in the operation of rolling adapted to the levelling water yield that can be suitable according to technology by three-way connection (pipe) road 20 in the operation of rolling.
