Described cutter formula carbon brush and conducting slip ring are Elastic Contact.
The power supply gatherer that the present invention is provided with mainly adopts elasticity to connect, can realize the flexible swing that power supply imports, wherein non-rigid contact between cutter formula carbon brush sheet and slip ring, reduce the frequency that carbon brush fractures, avoided contact area little and cause the phenomenon of loose contact, thereby stop fire odds, guarantee the safety of producing and improve the efficiency of producing.
In described power supply, import assembly and connected the cutting mechanism of being located on rotating disk.
Import assembly in power supply imports assembly and obtains power supply and flow to executing agency on rotating disk as cutting mechanism again from power supply.
Described rotating disk drives rotation by dynamical element.
Compared with prior art, the beneficial effect that the present invention has:
1. the cutting mechanism that it adopts can produce the cutting force of stable and uniform, can avoid the out-of-flatness of tubing otch, multitube bits phenomenon;
2. the servo follower adopting can improve the quality of tubing under the prerequisite that keeps Cutting dolly to synchronize with pipe production line speed, has reduced mechanical fault rate.
3. the power supply gatherer adopting can guarantee that Maximum Contact area produces power supply and powers to cutting mechanism, reduces the frequency that carbon brush fractures simultaneously, guarantees production safety and has improved production efficiency.
