The present invention relates to a kind of band sawing machine control system based on PLC, suitable for mechanical field.
Background technology
Band saw machine cuts class lathe as gold, is widely used in mechanical processing industry.As blanking procedure
Capital equipment, it is primarily adapted for use in cutting ordinary carbon steel, high-speed tool steel, bearing steel, low-alloy steel, stainless steel, aluminium, copper material etc.
Various bars and tubing.The band sawing machine is controlled using PLC, can automatically control feed length, automatic counting；Using special speed governing
Valve, the work speed of band sawing machine, feed pressure is changed with the change of cutting resistance, ensure that band sawing machine reaches optimal sawing
State, meet its requirement.
The content of the invention
The present invention proposes a kind of band sawing machine control system based on PLC, using special flow speed control valve, realizes that the work of sawing machine is entered
The adaptive adjustment of speed, the core component using PLC as band sawing machine control system, with reference to the application of touch-screen, make system work
Work is reliable, noise is small, easy to operate, meets the requirement of band sawing machine control system.
The technical solution adopted in the present invention is.
The control system has 3 motors, respectively saw wheel motor, cooling motor and Oil pump electrical machinery.Saw wheel motor and cold
But motor is controlled by contactor IBM1, Oil pump electrical machinery access KM2.
The control system is using DVP32EC types PLC as key control unit, and the type product design is compact, and price is low
Honest and clean, command function is powerful, and has 1 RS-232 port, to connect touch-screen, therefore in the industrial automation for solving user
During problem, there is very strong adaptability.
The software of the control system is made up of two parts, and respectively PLC control program and touch screen interface show program.
Touch-screen selects WQTT8048-070 type touch-screens.PLC control program shows sub- journey by system initialization subprogram, real-time parameter
Sequence, touch panel communication program, abnormal interrupt program, working mode change etc. form.
The hydraulic system is mainly made up of hoist cylinder, jaw clamping cylinder, feeding and clamping oil cylinder and feeding oil cylinder.Rise
Drop oil cylinder is mainly rapid increase and the work feed action for realizing saw frame, is realized in the special flow speed control valve of sawing machine of rodless cavity access
The adaptive adjustment of sawing machine feeding speed.Jaw clamping cylinder is mainly the pinching action for realizing the workpiece in sawing process.Send
Feed collet locking oil cylinder mainly coordinates feeding oil cylinder, realizes release and pinching action.Feeding oil cylinder mainly coordinates grating scale, realizes
Feed length is accurately positioned；Complete advance, the backward movement of feeding and clamping oil cylinder.
The beneficial effects of the invention are as follows：Core component of the control system using PLC as band sawing machine control system, with reference to tactile
The application of screen is touched, makes system reliable operation, noise small, easy to operate, meets the requirement of band sawing machine control system.
Brief description of the drawings
Fig. 1 is the system main circuit diagram of the present invention.
Fig. 2 is the system control loop of the present invention.
Fig. 3 is the Control System Software structure chart of the present invention.
Fig. 4 is the hydraulic system of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, analyze according to the actual requirements, the control system has the characteristics that：（1）The flexible whole system of system operatio
It is required to realize man-machine " dialogue ", you can to show by the Chinese interface of system and real-time Graphic State, understand system
Working condition such as speed, position and warning message etc., and can the parameter that pre-sets of real time modifying system.(2) saw frame work is entered
During sawing, the material of workpiece or the change of area of section directly affect sawing precision and saw blade for speed dynamic adjustment
Service life, therefore, from the special flow speed control valve of band sawing machine, the progress of the work feed speed of band sawing machine is adaptively adjusted, make
Band sawing machine is in optimum Working all the time.(3) measurement of the high traditional band sawing machine linear feed displacement of feeding positioning precision makes
It is scale, error is larger, and is difficult to improve cutting stock precision, therefore, from WTBS displacement transducers, improves blanking essence
Degree, is easy to implement self-feeding.
Control system has 3 motors, respectively saw wheel motor, cooling motor and Oil pump electrical machinery.Saw wheel motor and cooling electricity
Machine is controlled by contactor IBM1, Oil pump electrical machinery access KM2.
For control system using DVP32EC types PLC as key control unit, the type product design is compact, cheap, refers to
Make powerful, and have 1 RS-232 port, to connect touch-screen, therefore solving the problems, such as the industrial automation of user
When, there is very strong adaptability.
Such as Fig. 2, the software of control system is made up of two parts, and respectively PLC control program and touch screen interface show journey
Sequence.Touch-screen selects WQTT8048-070 type touch-screens.PLC control program is shown by system initialization subprogram, real-time parameter
Subprogram, touch panel communication program, abnormal interrupt program, working mode change etc. form.
Such as Fig. 3, the effect of initialization program is the display mode for setting touch-screen, sets messaging parameter, system reset,
Prepared for program below.The effect of real-time display subprogram is to show cutting speed, feed speed and cutting length etc..It is logical
Letter program effect is to realize touch-screen and PLC communication.Interrupt routine effect is to detect cutting length, the input to PLC
Output carries out data processing, compared with preliminary setting data.Working mode change effect is to realize manually and automatically flexible
Conversion.
Such as Fig. 4, hydraulic system is mainly made up of hoist cylinder, jaw clamping cylinder, feeding and clamping oil cylinder and feeding oil cylinder.
Hoist cylinder is mainly rapid increase and the work feed action for realizing saw frame, real in the special flow speed control valve of sawing machine of rodless cavity access
