Abstract
The utility model provides an electrohydraulic control device for a servo motor for use in a die casting machine, which belongs to the technical field of hydraulic transmission. The aim of the utility model is to overcome the drawbacks of the conventional motor hydraulic device and provide a low-carbon environment-friendly product. The die casting machine adopts the servo motor and a hydraulic technique of the servo motor. The utility model also discloses the die casting machine and a hydraulic system. The electrohydraulic control device for the servo motor is characterized by consisting of a control circuit, a servo driver, a servo motor, an oil pump and a servo motor group. When the technical scheme is adopted, energy consumption can be reduced by 30 to 80 percent; requirements for producing high-precision products can be met; and the volume of water for cooling oil can be reduced, and the change period oil can be shortened.
Description
Technical field
The electrofluidic control device of the servomotor that a kind of die casting machine that the utility model proposes is used belongs to the hydraulic drive field, and outstanding being fit to uses servomotor to make the work of hydraulic-driven die casting machine as power.
Background technology
Existing die casting machine kind is a lot, like metal die-casting machine, powder die casting machine, machined hydraulic press and plastic molding press etc.Along with development of science and technology, traditional motor hydraulic control device has following shortcoming: 1, energy consumption is big, no matter the working condition of die casting machine, the power of asynchronous machine does not all have minimizing.2, the invalid traffic of pressure oil is big.3, caloric value is big, increases cooling water amount.4, cost increases.So existing die casting machine is the energy-consuming product of non-low-carbon (LC).
Summary of the invention
The electrofluidic control device of the servomotor that a kind of die casting machine that the utility model proposes is used its objective is to overcome the shortcoming that has traditional motor hydraulic means now, reaches the product of low-carbon environment-friendly.
The utility model adopts servomotor and hydraulic technique thereof.
The electrofluidic control device of the servomotor that a kind of die casting machine is used comprises die casting machine and hydraulic system, it is characterized in that the hydraulic control system by the servomotor of being made up of control circuit, servo-driver, servomotor and oil pump; Control circuit connects servo-driver, and the out-put supply line of servo-driver connects servomotor, and servomotor connects oil pump, oil pump with oil pipe connect fuel tap plate on the die casting machine with oil sump so that control the exercises of die casting machine.
The electro-hydraulic device of the servomotor that above-described a kind of die casting machine is used is characterized in that servo-driver has flow and pressure signal to feed back to servomotor.
The utility model has the advantages that: servomotor is according to the variation of die casting machine load, and through the load of flow and pressure adjustment servomotor, comparable Induction Motor-Driven hydraulic system reduces by 30%-80% energy consumption; Satisfy the needs of production high accuracy product; Reduce the cool water quantity of cold oil and the cycle of more changing oil.
Description of drawings
Fig. 1 is the electrofluidic control device schematic diagram of the servomotor used of a kind of die casting machine.
Die casting machine 1, control circuit 2, servo-driver 3, power line 4, flow and pressure signal 5, servomotor 6, oil pump 7, fuel tap plate 8, oil sump 9.
The specific embodiment
Lift the application examples explanation this programme on die casting machine, Fig. 1 is the electro-hydraulic device control principle figure of the servomotor used of a kind of die casting machine at present, and this device control circuit 2, servo-driver 3, power line 4, servomotor 6 and oil pump 7 are formed.Its course of work is behind the electric power starting, to be pressed the action request of die casting machine by the control circuit 2 on the former die casting machine 1; The pressure of each action, the analog quantity output parameter of flow are imported the servo-driver 3 in the servo-drive system; After the servo-driver high-speed computation, start servomotor 6 through power line 4, servomotor rotates oil pump work; Through the work of fuel tap plate 8 drive pressure casting machines, oil recycles through oil sump 9 oil pump required pressure oil.In order further to improve the accuracy of oil pump output pressure and flow, flow and pressure signal 5 make it system accurately by the setting requirement in the former die casting machine control circuit, accomplish the exercises of die casting machine, have guaranteed the precision and the output requirement of goods.
