Abstract
The utility model discloses a fly-saw control system which comprises a PLC controller. The PLC controller is connected with a local I/O expansion module, and is connected with a remote I/O expansion module through an on-site bus. The PLC controller is also connected with a digital control system NCK, and is responsible for regulating digital control programs. The digital control system NCK is connected with a shaft driving module, and the shaft driving module is connected with a motor. The utility model also comprises one set of PC which is used as a man-machine interface, the PC is connected with the PLC controller through an RS485. The fly-saw control system of the utility model uses the digital control system NCK to replace a PLC to carry out motion control, can realize the optimizing control for movement and can obtain high positioning accuracy. The utility model adopts a full digit control mode, and introduces the scheme of high-speed synchronous control for large quantity. The high-speed moving process of large inertia objects is ensured, and the accurate control of the route and the speed is simultaneously achieved.
Description
Technical field
The utility model relates to a kind of control system of Metal Cutting equipment, particularly a kind of control system that flies to saw.
Background technology
The profiling milling is the large-scale a kind of more advanced cutting mode that flies to saw employing, and the cutting mechanism of profiling milling saw is by saw disc, the radial feed axle, and compositions such as saw blade, surface cutting one circle along welded tube during cutting cuts off welded tube.The advantage of this cutting mode is when cutting heavy caliber welded tube, need not to increase the size of saw blade, need not change pipe and square tube that saw blade just can cut different sizes as long as planned cutting track.It is complicated that but physical construction is sawed not only in the profiling milling, and machining accuracy requires high, and also very high to the requirement of control system.
Existing control system generally adopts PLC as master control system, and all motion controls all realize by the functional template of PLC.Because the restriction of control system, fly both at home and abroad saw equipment particularly metal cut off and fly saw equipment in order to guarantee cutting power, often the power amplification of each motor.Thereby make equipment volume more huge, and can't optimize cutting track and cutting speed, only press the fixation locus operation, also just can't ensure expensive saw life according to workpiece material and speed of production.
The utility model content
The technical problems to be solved in the utility model provides higher the flying of a kind of bearing accuracy and saws control system.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind ofly fly to saw control system, comprise the PLC controller, described PLC controller connects local I/O expansion module, and be connected with the remote I/O expansion module by fieldbus, described PLC controller also is connected with digital control system NCK, and be responsible for calling numerical control program, described digital control system NCK connects an axle driver module, the axle driver module is connected with motor, comprises that also a PC as man-machine interface is connected with the PLC controller by RS485.
Of the present utility modelly fly to saw control system and replace PLC to carry out motion control, can realize to reach higher bearing accuracy the optimal control of motion with digital control system NCK.The utility model adopts total prosecutor formula, quotes a large amount of high-speed synchronous controlling schemes, in the accurate control that guarantees to reach simultaneously at big inertia objects at high speed motion process path and speed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the block diagram of system that flies to saw control system of the present utility model.
Embodiment
As shown in Figure 1, digital control system NCK and PLC constitute the core of control system of the present utility model, can adopt the digital control system SINUMERIK-840D of Siemens to implement control and since SINUMERIK-840D inner integrated the PLC module, therefore need not again external PLC controller.PLC connects switch, solenoid valve etc. by local I/O expansion module, realizes the action control to peripherals; PLC also is connected with the remote I/O expansion module by fieldbus, and the remote I/O expansion module can connect button, pilot lamp, alarm of remote console etc.PC as man machine operation interface is connected with PLC by RS485, and PC can be accepted the input of technological parameter, and the calculating processing track.Flying saw mainly is made up of two big subsystems: table system and saw disc system, wherein chassis is done straight reciprocating motion by a motor-driven, saw disc is rotated by an Electric Machine Control, and two saw blades are installed on the saw disc, each saw blade rotatablely move and feed motion respectively by an Electric Machine Control.Digital control system NCK is connected with each motor by the axle driver module as the core of motion control, calls numerical control program by PLC, is carried out the track interpolation of working motion by digital control system NCK control motor.
Claims (1)
1. one kind flies to saw control system, comprise the PLC controller, it is characterized in that: described PLC controller connects local I/O expansion module, and be connected with the remote I/O expansion module by fieldbus, described PLC controller also is connected with digital control system NCK, and is responsible for calling numerical control program, and described digital control system NCK connects an axle driver module, the axle driver module is connected with motor, comprises that also a PC as man-machine interface is connected with the PLC controller by RS485.
