The second transmission component 260, the second transmission component 260 and the first transmission component are equipped between one shaft 211 and the second shaft 212
250 structures are identical, so that auxiliary propelling machine 230 also has preferable synchronism.
As shown best in figures 2 and 11, the first rotating shaft 211 of auxiliary propelling machine 230 is equipped with third hand tap gear 231, the first driving
The drive shaft 241 of component 240 extends towards auxiliary propelling machine 230, and drive shaft 241 is equipped with and engages with third hand tap gear 231
The 4th bevel gear 232.First driving assembly 240 drives auxiliary propelling machine 230 and active walking mechanism 210 simultaneously, so that
The two has preferable synchronism, also more stable when transmitting rectangular steel tube.
As shown in figure 11, the number of teeth of third hand tap gear 231 is less than the number of teeth on the 4th bevel gear 232, so that auxiliary
Travel speed in walking mechanism 230 is greater than the travel speed of active walking mechanism 210 and driven walking structure.Due to square bar
, it can be seen that rectangular steel tube speed can be slack-off, can after medium frequency induction heater 300 and cooling device 400 are processed when pipe is processed
It is stacked to avoid adjacent two rectangular steel tubes by medium frequency induction heater 300.
Specific implementation process: firstly, rectangular steel tube is pushed into driven walking mechanism by rubber roller 101 of walking by staff
In 220, the second driving assembly 270 drives driven walking structure, and the driven driving of walking mechanism 220 rectangular steel tube advance, which is gone forward side by side, to be become owner of
In dynamic walking mechanism 210；
Further driving rectangular steel tube advances and enters medium frequency induction heater 300 active walking mechanism 210；
Rectangular steel tube enters in the square through hole 312 of medium frequency induction heater 300,313 other side of inductor of rectangular setting
Shape steel pipe homogeneous heating；
Rectangular steel tube after 400 pairs of cooling device heating carries out spraying cooling, and the upper water box 401 of cooling device 400 is under
The upper and lower surfaces of the square shaped steel pipe respectively of water tank 402 are cooled down；
It is advanced further after direction steel pipe is cooling, into auxiliary propelling machine 230, auxiliary propelling machine 230 into one
Step driving rectangular steel tube advances, and rectangular steel tube is transmitted on the walking rubber roller 101 of 100 rear side of mobile holder, gradually to it
After cooling, then pack up.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
