Description

A kind of vulcanizer without sensor servo drive system
Technical field
The present invention relates to vulcanizer technical field, and in particular to a kind of vulcanizer without sensor servo drive system.
Background technology
Energy-saving vulcanizer is generally by injecting systems, Clamping System, electric control system, lubricating system, temperature control system System, safety monitoring system and servo drive system composition.Wherein, servo drive system is more crucial portion in whole device Point, with continuing to develop for science and technology, the servo drive system of existing energy-saving vulcanizer generally uses closed loop feedback control, passes through The pressure sensor of detecting system oil pressure and the velocity sensor being installed on servomotor do feedback signal to servo-driver.
Due to the increase of sensor, system destabilizing factor is caused to increase, often because sensor fault causes vulcanizer Stop production, cause economic loss;And the sensor control circuit of sensor and matching is increased due to system, section is result in Energy type vulcanizer cost is higher.
The content of the invention
The invention aims to overcome the shortcomings of prior art exist, there is provided a kind of vulcanizer without sensor servo Drive system.
The present invention is achieved by the following technical solutions:A kind of vulcanizer without sensor servo drive system, it is described Vulcanizer without sensor servo drive system by controller of vulcanizer, servo-driver, servomotor, oil pump, oil cylinder, ratio Pressure valve, reversal valve, overflow valve, fuel tank composition, the servo-driver output interface are electrically connected with proportional pressure valve, the sulphur The flow signal for changing machine controller is electrically connected with servo-driver, the fuel injection pressure signal and servo-driver of the controller of vulcanizer Electrical connection, the servo-driver built-in signal comparator, the signal comparison other of the signal comparator is servo-driver Output current and fuel injection pressure signal, the servo-driver is by signal comparator running mode switching, the servo-driver fortune Row mode is respectively velocity mode and oil pressure pattern, and described signal comparator detects servo-driver output current more than oil During pressure signal, the servo-driver presses oil pressure mode operation, and described signal comparator detects servo-driver output electricity When stream is not more than fuel injection pressure signal, the servo-driver is run by velocity mode.
The signal type that the servo-driver output interface is electrically connected with proportional pressure valve is direct current 0-1A current signals.
The servomotor is Speedless sensor type.
The servo-driver in velocity mode run when, the oil pump speed of service is more than 200 turns for per minute.
When the servo-driver is in oil pressure mode operation, it is 0 turn per minute that the oil pump slows down.
The oil pump is gear pump or plunger displacement pump or screw pump.
The beneficial effects of the invention are as follows:The present invention is using without sensor servo drive system, the signal ratio of signal comparator It is servo-driver output current and fuel injection pressure signal compared with object, servo-driver passes through signal comparator running mode switching, by In without pressure sensor and velocity sensor and corresponding match circuit, this servo drive system stability substantially increases, while System cost can be significantly reduced.
Brief description of the drawings
Fig. 1 is structural principle block diagram of the invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in figure 1, a kind of vulcanizer without sensor servo drive system, the vulcanizer drives without sensor servo Dynamic system by controller of vulcanizer, servo-driver, servomotor, oil pump, oil cylinder, proportional pressure valve, reversal valve, overflow valve, Fuel tank is constituted.
Servo-driver output interface is electrically connected with proportional pressure valve, the flow signal and servo-drive of controller of vulcanizer Device is electrically connected, and the fuel injection pressure signal of controller of vulcanizer is electrically connected with servo-driver, and servo-driver is electrically connected with servomotor, Servomotor is connected with oil pump, and oil pump is connected with reversal valve, and reversal valve is connected with oil cylinder, and overflow valve is connected with oil pump, overflow valve It is connected with fuel tank, proportional pressure valve is connected with fuel tank, proportional pressure valve is connected with oil pump, proportional pressure valve is connected with reversal valve, Reversal valve is connected with fuel tank.
Servo-driver built-in signal comparator, the signal comparison other of signal comparator is servo-driver output current With fuel injection pressure signal, by signal comparator running mode switching, servo-driver operational mode is respectively speed to servo-driver Pattern and oil pressure pattern.
When signal comparator detects servo-driver output current more than fuel injection pressure signal, servo-driver presses oil pressure pattern Operation, when servo-driver is in oil pressure mode operation, it is 0 turn per minute that the oil pump slows down, meanwhile, servo-driver is given Signal drives proportional pressure valve, and system oil pressure passing ratio pressure valve releases back to fuel tank.
Signal comparator detect servo-driver output current no more than fuel injection pressure signal when, the servo-driver by speed Degree mode operation, servo-driver in velocity mode run when, the oil pump speed of service is per minute to be more than 200 turns.
