The utility model discloses a mould opening and closing synchronization mechanism of a helicopter composite material blade mould pressing system, which belongs to the composite material forming technique and relates to an improvement of the helicopter composite material blade mould pressing system. The mould opening and closing synchronization mechanism comprises two mould opening and closing oil cylinders (1), two upper mould connecting sleeves (2), two reversing valves, a hydraulic unit and a control device, and is characterized in that each mould opening and closing oil cylinder (1) is provided with a mould opening and closing oil cylinder closed loop feedback control system which is formed by a displacement sensor (4), a reflector panel (3), a proportional flow valve, the reversing valves and the control device. The utility model is high in synchronous control precision, and can guarantee movement of mould opening and closing of the composite material blade mould pressing system to be accurate and synchronous.
Description
Technical field
The utility model belongs to the composite material forming technology, relates to the improvement to the composite material blade of helicopter moulding system.
Background technology
The folding mould of present composite material blade of helicopter moulding system is finished by two folding mould oil cylinders, in order to realize that two folding mould oil cylinders are synchronized with the movement, middle synchronous valve and the reversal valve installed at Hydraulic Station, the output port of Hydraulic Station is communicated with the input port of reversal valve, the output port of reversal valve is communicated with the input port of synchronous valve, and the output port of synchronous valve is communicated with the oil inlet and outlet of two folding mould oil cylinders respectively.Its shortcoming is: synchronous control accuracy is poor.Because two folding mould oil cylinders are adopted open loop control in parallel, and two suffered at the volley load differences of oil cylinder, and the control accuracy of synchronous valve is lower, be difficult to guarantee that the motion of folding mould oil cylinder accurately synchronously, thereby can cause the steady or not stuck phenomenon of folding mould, have a strong impact on the production qualification rate of composite material blade of helicopter.
Summary of the invention
The purpose of this utility model is: propose a kind of synchronous control accuracy height, can guarantee accurately synchronous composite material blade of helicopter moulding system folding mould lazy-tongs of composite material blade moulding system folding mould motion, to improve the production qualification rate of composite material blade of helicopter.
The technical solution of the utility model is: composite material blade of helicopter moulding system folding mould lazy-tongs, comprise two folding mould oil cylinders, two patrix adapter sleeves, two reversal valves, Hydraulic Station and control device, two output ports of reversal valve are communicated with two oil inlet and outlets of folding mould oil cylinder, and control device is by two folding mould oil cylinder actions of Hydraulic Station control; It is characterized in that, for each folding mould oil cylinder, by a folding mould oil cylinder closed loop feedback control system of forming by displacement transducer, reflector, proportional flow control valve, reversal valve and control device; Displacement transducer is installed on the output end face of folding mould oil cylinder, reflector is installed on the end face of patrix adapter sleeve, this end face is relative with the output end face of folding mould oil cylinder, the installation site of reflector is corresponding with displacement transducer, the output of displacement transducer is connected with the corresponding input of control device, proportional flow control valve is installed in the Hydraulic Station, the output port of proportional flow control valve is communicated with the input port of reversal valve, the input port of proportional flow control valve is communicated with the output port of Hydraulic Station, and the control signal input of proportional flow control valve is connected with the proportional flow control valve control signal output of control device.
The utility model has the advantages that: the synchronous control accuracy height can guarantee that the motion of composite material blade moulding system folding mould accurately synchronously.Thereby solved the problem of following two aspects: the first, avoided because the folding mould is asynchronous, upper and lower mould is matched moulds normally, thereby causes scrapping of blade to improve product percent of pass; The second, significantly reduced cost, because blade costs an arm and a leg, the utility model has been eliminated because of the folding mould asynchronous, and what upper and lower mould can not normal occlusion be molded as scraps, thereby has reduced the cost of blade, has guaranteed Development Schedule.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1, composite material blade of helicopter moulding system folding mould lazy-tongs, comprise two folding mould oil cylinders 1, two patrix adapter sleeves 2, two reversal valves, Hydraulic Station and control device, two output ports of reversal valve are communicated with two oil inlet and outlets of folding mould oil cylinder 1, and control device is by 1 action of two folding mould oil cylinders of Hydraulic Station control; It is characterized in that, for each folding mould oil cylinder 1, by a folding mould oil cylinder closed loop feedback control system of forming by displacement transducer 4, reflector 3, proportional flow control valve, reversal valve and control device; Displacement transducer 4 is installed on the output end face of folding mould oil cylinder 1, reflector 3 is installed on the end face of patrix adapter sleeve 2, this end face is relative with the output end face of folding mould oil cylinder 1, the installation site of reflector 3 is corresponding with displacement transducer 4, the output of displacement transducer 4 is connected with the corresponding input of control device, proportional flow control valve is installed in the Hydraulic Station, the output port of proportional flow control valve is communicated with the input port of reversal valve, the input port of proportional flow control valve is communicated with the output port of Hydraulic Station, and the control signal input of proportional flow control valve is connected with the proportional flow control valve control signal output of control device.
Operation principle of the present utility model is: the fuel delivery of passing ratio flow valve control folding mould oil cylinder in hydraulic circuit, in the process of folding mould, the Displacement Feedback that the end face top offset sensor of folding mould oil cylinder constantly moves patrix is given control device, control device compares the displacement of oil cylinder, and then the proportional flow control valve in the control Hydraulic Station, adjustment enters the flow velocity of the fluid of two folding mould oil cylinders, carry out closed-loop control, the displacement that guarantees mould both sides folding mould oil cylinder is identical, thereby guaranteed the accurately synchronous of folding mould motion, avoid patrix stuck in moving process, improved the production qualification rate of composite material blade of helicopter.
