Description
Technical Field
The invention discloses a flywheel energy storage sawing device for a hot sawing machine, relates to high-speed sawing equipment, and particularly relates to an energy storage device for the hot sawing machine which stores energy by means of a flywheel.
Background
In the production and processing process of the seamless steel tube, the cutting of the heat tube blank is a very critical link, and the power driving mode of the sawing cutter is very important in the link, so that the quality of the cut surface of the tube blank and the cutting time are directly influenced. The existing hot sawing machine mainly comprises a pendulum type hot sawing machine, a roller sliding seat type hot sawing machine and a connecting rod type hot sawing machine, but the power driving modes mainly comprise two modes: belt drive mode or driving motor direct drive mode:
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 a direct drive mode of a driving motor generally drives a saw blade directly, and the motor is large in impact during sawing and easy to damage.
Meanwhile, in the existing seamless steel pipe industry, the most used output and sales are pipes with the specification of phi 180-phi 350, and the existing cutting machine needs at least 10 seconds to cut the hot pipe blank with the specification; for the production of seamless steel pipes, a long time of movement stop of the hot pipe blank on the production line is required, and the temperature of the pipe blank is reduced, which affects the next production process, so that the cutting time is required to be reduced to ensure the continuous execution of the subsequent processing steps.
Aiming at the problems in the prior art, the novel flywheel energy storage sawing device for the hot sawing machine is researched and designed, so that the problems in the prior art are overcome.
Disclosure of Invention
In view of the problems in the prior art, the invention aims to research and design a novel flywheel energy storage sawing device for a hot sawing machine. The invention adopts the flywheel energy storage principle, and utilizes the flywheel energy storage to drive the saw blade to rotate for cutting, so as to solve the problems in the prior art: 1. the belt transmits kinetic energy, and the sawing speed is unstable; 2. the belt transmits kinetic energy, so that the belt loss is large, and the replacement period is short; 3. the direct transmission mode of the driving motor is easy to damage due to the large impact force of the motor; 4. the direct transmission mode of the driving motor causes the vibration of the saw blade to be increased due to the large vibration of the motor, so that the quality of the cut surface of the tube blank is low; 5. the direct transmission mode of the driving motor causes the problems of saw blade damage, short service life and the like due to the fact that the motor vibrates greatly and the saw blade vibrates greatly.
The technical solution of the invention is realized as follows:
the flywheel energy storage sawing device is arranged in the hot saw box and is connected with an eccentric feeding device which is arranged in the hot saw box side by side into a whole, and a saw blade is arranged on the flywheel energy storage sawing device through a saw blade chuck and a saw blade fixing disc; the method is characterized in that: the flywheel energy storage sawing device comprises: the device comprises a sawing input shaft, a sawing output shaft, a sawing transmission gear A, a sawing transmission gear B and a sawing energy storage flywheel;
the sawing input shaft is arranged in a shaft hole of a feeding eccentric gear of an eccentric feeding device through a bearing; the sawing input shaft is connected with a sawing transmission gear A in a key way;
the sawing output shaft is reversely arranged in a shaft hole of a feeding eccentric gear of the eccentric feeding device through a bearing; the sawing output shaft is connected with a sawing transmission gear B in a key way;
the sawing transmission gear A is meshed with the sawing transmission gear B and transmits transmission force;
the sawing energy storage flywheel is connected with a sawing input shaft outside the hot sawing box in an interference fit manner to form a whole;
the sawing output shaft is connected with the saw blade fixing disc outside the hot saw box through key connection.
The sawing input shaft is connected and installed with the center of the feeding eccentric gear through the bearing, and the axis of the sawing input shaft is kept concentric with the center of the feeding eccentric gear.
The sawing output shaft is arranged at the eccentric position of the feeding eccentric gear through a bearing, and the axis of the sawing output shaft and the eccentric center of the feeding eccentric gear are kept concentric.
The invention uses flywheel energy storage to cut off the heat pipe blank at high speed; firstly, a sawing input shaft is driven by a motor to rotate at a high speed to store energy on a sawing energy storage flywheel, and the rotating speed of the sawing energy storage flywheel is increased to a rated speed; simultaneously, the tube blank is conveyed to a sawing position by a sizing trolley, a feeding motor drives a feeding input shaft after the tube blank is clamped by a clamp, and a feeding driving gear drives a feeding eccentric gear to drive a saw blade shaft and a saw blade to saw the tube blank; at this time, the saw cutting energy storage flywheel transmits the stored energy to the saw blade through the saw cutting transmission gear. And after each sawing is finished, the energy storage flywheel is sawed, and then energy storage is carried out to wait for the next sawing.
The advantages of the invention are obvious and mainly expressed in that:
1. the invention adopts a flywheel energy storage mode for driving, thereby avoiding the problem of unstable sawing speed when the belt transmits kinetic energy;
2. the invention adopts a flywheel energy storage mode to drive, thereby avoiding the problems of large belt loss, frequent replacement and waste caused by the transmission of kinetic energy by the belt;
3. the invention adopts a flywheel energy storage mode for driving, thereby avoiding the direct transmission mode of the driving motor from damaging the motor due to large impact force of the motor;
4. the invention adopts the flywheel energy storage mode for driving, thereby avoiding the problem of low precision of the tube blank cutting surface caused by the increased vibration of the saw blade due to the large vibration of the motor in the direct transmission mode of the driving motor;
5. the invention adopts the flywheel energy storage mode for driving, thereby avoiding the problems of saw blade damage and short service life caused by the increased vibration of the saw blade due to the large vibration of the motor in the direct transmission mode of the driving motor.
