The traditional process mainly comprises a pendulum type hot sawing machine, a roller sliding seat type hot sawing machine, a connecting rod type hot sawing machine and the like; the pendulum type hot sawing machine has limited sawing travel, poor rigidity and large vibration, and belongs to belt transmission; the roller slide type feeding speed is low, meanwhile, the clearance of the roller slide type can cause deflection of the saw blade, and the motor is directly driven; the connecting rod type hot sawing machine has low productivity, poor overall rigidity, difficult sawing quality meeting the requirements, short service life of the saw blade and direct driving of the motor. The transmission modes of the sawing devices are as follows: belt drive or direct drive: the sawing speed of the hot sawing machine in a belt transmission mode is unstable and is frequently lost, and the belt is frequently replaced; the hot sawing machine with direct transmission mode has the advantages that the motor directly drives the saw blade, the impact on the motor is large during sawing, and the motor is easy to damage.
In conclusion, the traditional process has the defects of long sawing period, difficult guarantee of the perpendicularity of the sawing end face, large deflection of the saw blade, low service life of the saw blade and the like.
