Abstract
The invention relates to a buffer system of a hydraulic machine. The buffer system is characterized in that both sides of a base are symmetrically and fixedly provided with two same plunger cylinders, the cavities of the plunger cylinders are simultaneously connected with the inside of a piston cavity of a control hydraulic cylinder, the middle part of a piston of the control hydraulic cylinder is fixedly provided with a thread sleeve, a screw rod is arranged in a thread hole which is arranged on the middle part of the thread sleeve, the end of the screw rod is fixedly connected with an output shaft of a speed reducer, a shaft of a servo motor is fixedly connected with an input shaft of the speed reducer, and the piston cavity of the control hydraulic cylinder is connected with the inside of an oil tank through a pipeline of an one-way valve. The buffer system has the advantages that the automation degree is high, and the buffering effect is good.
Description
Technical field
The present invention relates to hydraulic press, be specifically related to the hydraulic press buffer system, belong to the hydraulic press technical field.
Background technology
In order to alleviate the hydraulic shock that produces in the hydraulic press course of work and the harm that produces thus, in some hydraulic presses, all be provided with buffer system, but, existing hydraulic press buffer system is made of single plunger case, its effect is equivalent to the effect of spring, but, hydraulic press in the course of the work, the residing diverse location of slide block, the cushion effect of its requirement also requires different, and like this, existing buffer unit can't be regulated corresponding cushion effect according to the situation of the reality of work of hydraulic press, so, have the relatively poor defective of buffering effect.
Summary of the invention
The object of the invention is to: the existing defects of buffer system for existing hydraulic press, the invention provides a kind of novel hydraulic press buffer system, overcome the existing existing defects of hydraulic press buffer system.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of hydraulic press buffer system, it comprises slide block, base, plunger case, fuel tank, the control hydraulic cylinder, screw shell, screw mandrel, reductor, servomotor, it is characterized in that: the bilateral symmetry of base install and fix two identical plunger cases, the inner chamber of described plunger case links to each other with the plunger shaft of control hydraulic cylinder is inner simultaneously, in the middle of the piston of control hydraulic cylinder, be mounted with screw shell, be provided with screw mandrel in the neutral threaded hole of described screw shell, the end of screw mandrel and the output shaft of reductor are connected and fixed, the axle of servomotor and the power shaft of reductor are connected and fixed, the plunger shaft of control hydraulic cylinder links to each other with fuel tank internal with pipeline by check valve, and described check valve has the function of oppositely ending from fuel tank to control hydraulic cylinder conducting.
Beneficial effect: in the present invention, servomotor is under the control of program, the rotation harmonious with the course of action of slide block, hydraulic oil in plunger case speed is on request discharged, thereby reach the purpose by the requirement control cushion effect of setting, so the present invention has preferably advantage of automaticity height, buffering effect.
