Abstract
The utility model discloses a control system for a die-casting machine and in particular relates to a servo control system for the die-casting machine. The servo control system comprises a control valve, an oil tank, a quantitative pump, a hydraulic cylinder, a servo motor, an encoder, a servo drive controller and a pressure sensor, wherein an oil inlet pipe and an oil outlet pipe are connected between the control valve and the oil tank; the quantitative pump is arranged on the oil outlet pipe; the servo motor is in transmission connection with the quantitative pump; the encoder is arranged on the servo motor, and an output signal of the encoder is input to the servo drive controller; the pressure sensor is arranged on the oil outlet pipe, and an output signal of the pressure sensor is also input to the servo drive controller; a hard sensor protective cover is sleeved on the pressure sensor; and a hard encoder protective cover is sleeved on the encoder. The technical defects that the pressure sensor and the encoder are not provided with any protection devices and are directly exposed in a die-casting workshop so as to be easily damaged by the casting piece or manually in the conventional servo control system for the die-casting machine are overcome, and the servo control system for the die-casting machine has the advantages of high operating stability, long service life and the like.
Description
Technical field
The utility model relates to the servo-control system of a kind of control system of die casting machine, particularly die casting machine.
Background technology
In the control system of existing die casting machine very major part be all to adopt servo-control system, it comprises control valve, fuel tank, flowline, oil return pipe, constant displacement pump, hydraulic jack, servomotor, encoder, servo drive controller and pressure sensor, described encoder is arranged on servomotor, its output signal inputs to servo drive controller, described pressure sensor is arranged on flowline, its output signal also inputs to servo drive controller, it has less energy consumption, good stability, the advantage such as tight ness rating is high and noise is little.
But there is a problem in the servo-control system of above-mentioned die casting machine; pressure sensor and encoder are all precision components; pressure sensor and encoder are all without any protective device in said structure; but be directly exposed in Die Casting Workshop; therefore easily be cast part or artificial destruction, affect the work of die casting machine integral body.
The utility model content
The purpose of this utility model is to provide a kind of pressure sensor and encoder by the servo-control system of the low die casting machine of F. O. D possibility in order to solve above-mentioned the deficiencies in the prior art.
to achieve these goals, the servo-control system of the die casting machine that the utility model is designed, comprise control valve, fuel tank, constant displacement pump, hydraulic jack, servomotor, encoder, servo drive controller and pressure sensor, be connected with oil inlet pipe and flowline between control valve and fuel tank, constant displacement pump is arranged on flowline, servomotor and constant displacement pump are in transmission connection, encoder is arranged on servomotor, its output signal inputs to servo drive controller, pressure sensor is arranged on flowline, its output signal also inputs to servo drive controller, be socketed with the hard sensor protective sleeve outside pressure sensor, be socketed with hard encoder protective sleeve outside encoder.
The servo-control system of the die casting machine that the utility model obtains; in its structure, pressure sensor is socketed with the hard sensor protective sleeve outward; be socketed with hard encoder protective sleeve outside encoder; avoided pressure sensor and encoder to be directly exposed in working environment; reduce it by the possibility of F. O. D; make the good operating stability of servo-control system integral body, long service life.
