100 enter in the pipe process of heat transmission equipment 120, and drawstring closes up naturally, and expander roll mounting seat 22 drives the phase of expander roll guide pad 70
Mutually it is stacked, and completes an expander roll.Expander roll mounting seat 22 in extraction, draws expander roll 100 from heat transmission equipment 120
Rope is gradually straightened, and synchronous drive expander roll guide pad 70 slides along the first guide rail 211 during drawstring stretches so that each swollen
Bar guide pad 70 is scattered to be arranged at intervals on expander roll workbench 21.
Referring again to Fig. 7, the pipe expanding equipment for finned tube also includes flaring mechanism 90.The flaring mechanism 90 fills
It is located on the expander roll workbench 21, the flaring mechanism 90 includes the flaring head 91 for expander.The tube expansion of heat transmission equipment 120 is complete
Cheng Hou, flaring head 91 is docked with the expander workpiece 121 for treating tube enlarging operation in heat transmission equipment 120, pass through the second driving
Mechanism 40 drives expander roll workbench 21 to move, and expander roll workbench 21 drives flaring head 91 and flaring head 91 is pushed into expander workpiece
In 121, to complete the operation of the tube expansion of expander workpiece 121.In this way, relative to the tube expansion of the prior art by heat transmission equipment 120
The mode carried out with enlarging in different station, after the tube expansion of heat exchanging equipment 120 terminates, heat transmission equipment 120 still exists the present invention
In workpiece placement station 140, and enlarging operation can be carried out with heat exchanging equipment 120, phase is transferred to without heat transmission equipment 120 is removed
The enlarging station answered, accordingly simplify so as to eliminate clamping material step, tube expansion expander technique up and down, the tube expansion of heat transmission equipment 120
The operating efficiency of enlarging is improved.
The flaring mechanism 90 includes base 92, cylinder 93, the motor 95 of gear-box 94 and the 5th.Base 92 and expander roll work
Make platform 21 to be slidably matched.In embodiments of the present invention, base 92 is provided with the 5th guide rail 921, and expander roll workbench 21 is provided with and the 5th
The 7th sliding part 28 that guide rail 921 is slidably matched, the 7th sliding part 28 are installed on the 5th guide rail 921.Cylinder 93 is installed in swollen
On bar workbench 21, cylinder 93 is used to drive base 92 to move relative to expander roll workbench 21.Gear-box 94 is installed in base 92
On.
Fig. 9 and Figure 10 are referred to, gear-box 94 has a torque input shaft 941, driving wheel 942, multiple driven pulleys 943
With multiple torque output shafts 944.Torque input shaft 941 is by torque transmission to driving wheel 942, driving wheel 942 and the phase of driven pulley 943
Mutually engagement, driving wheel 942 are respectively connected with torque output shaft 944 with driven pulley 943.Torque input shaft 941 and the torque of motor are defeated
Shaft 944 is connected, and the torque output shaft 944 of gear-box 94 is connected with flaring head 91.In this way, after the 5th motor 95 rotates, pass through
Gear-box 94 drives multiple synchronous axial systems of flaring head 91, it is possible to achieve multiple tunnel synchronization tube enlarging operations.
Figure 11 is referred to, flaring head 91 is connected by connecting rod 96 with torque output shaft 944.In the expander of expander workpiece 121
Before operation, drive base 92 to be moved along the 5th guide rail 921 of expander roll workbench 21 by cylinder 93, flaring head 91 is stretched
Go out so that flaring head 91 is relative with expander workpiece 121 to be connect, to be prepared to enter into the follow-up enlarging of expander workpiece 121 operation.Expander
Part 121 terminates tube enlarging operation and then drives base 92 to be moved along the 5th guide rail 921 of expander roll workbench 21 by cylinder 93
It is dynamic, then flaring head 91 is withdrawn.
Figure 12 is referred to, flaring head 91 is cone-shaped, and the side wall and the angle a of the axial direction of flaring head 91 of flaring head 91 are
10~20 degree.So, flaring head 91 is advanced in expander workpiece 121 that suffered resistance is smaller, and expander workpiece 121 is in expander mistake
Just metaboly is susceptible in journey.Preferably, flaring head 91 is advanced to by the mistake of expander workpiece 121 using expander roll workbench 21
Cheng Zhong, the 5th motor 95 driving flaring head 91 rotate, rotate propulsion mode, can directly push away mode relative to prior art, can be significantly
Reduce the resistance suffered by flaring head 91, flaring head 91 can be easy to carry out tube enlarging operation to expander workpiece 121.
The side wall of cone-shaped flaring head 91 is provided with more than one recess or more than one flat zone 911, and recess or flat
Flat area 911 is set around the side wall of flaring head 91.There is flat zone 911 or recess on flaring head 91, in the rotation process of flaring head 91,
Entirety remains as cone-shaped, can normally realize tube enlarging operation.Recess or flat zone 911 on flaring head 91 cause flaring head 91
Form gap between the madial wall of expander workpiece 121, in order to expander workpiece 121 in expanding procedure inside and outside airflow, and
And it is easy in time distribute caused heat in expanding procedure.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
