The bottom dead centre switch adopting lathe to provide for the control of cutting journey or the time relay more.Use bottom dead centre switch to cause the knife rest when performing shear action must run to bottom dead centre and could perform backhaul, work efficiency is low; And service time, relay cannot ensure high precision, and cannot Real-time Feedback when the position at front rest place.
Output pressure many employings switch control rule pressure valve, constant pressure; What have has driving switch, can select large, medium and small third gear Output pressure.Such control mode cannot according to the sheet material of various material and thickness, the output of adjustment shear pressure.
Therefore, it is low to there is control accuracy in low side shear controller, the shortcoming that automaticity is low.Cannot Real-Time Monitoring and control gap, shearing inclination, cut journey and shear pressure.
Summary of the invention
The technical problems to be solved in the utility model is that existing plate shearing machine control accuracy is low, cannot realize shearing inclination, shear gap, the control of cutting journey and pressure and Real-Time Monitoring, further existing control system of cutting plate machine cut process control and Stress control is dumb
The technical solution of the utility model is: a kind of lock formula control system of cutting plate machine, comprise controller, sensor unit, man-machine interaction unit and control output unit, sensor unit, man-machine interaction unit are connected with controller respectively with control output unit, sensor unit comprises lower slide range sensor, upper tool post displacement transducer, lower slide displacement transducer and upper tool post angular transducer, and each sensor is connected to controller by AD conversion module.
Described man-machine interaction unit comprises coding handwheel and display screen, and coding handwheel is connected to controller by AD conversion module, and display screen is connected by DPRAM with controller.
As preferably, described display screen is touch display screen.
Further, described control output unit comprises proportional amplifier and hydraulic proportion valve, and the output of controller is connected to proportional amplifier by D/A conversion module, and the output of proportional amplifier connects hydraulic proportion valve.
Further, controller is also provided with USB interface.
The utility model realizes the monitoring to plate shearing machine work by upper lower slide range sensor, upper tool post displacement transducer, lower slide displacement transducer and upper tool post angular transducer, control is assisted to cut journey by sensor unit, improve the shear precision of plate shearing machine, improve the displacement accuracy of upper tool post and lower slide, improve the precision that shearing inclination controls; Adopt coding handwheel handled easily personnel can carry out manual input signals control; Adopt controller to send exact figure signal to proportional amplifier, effectively can control shear pressure in conjunction with hydraulic proportion valve; Human-computer interaction module makes Monitoring Data more directly perceived, improves the property easy to use of plate shearing machine; Adopt USB interface handled easily personnel can send corresponding control program to controller, improve the pervasive performance of plate shearing machine.
