The main hydraulic cylinder driving on top, 1 left side of fuselage are equipped with left hydraulic cylinder 3, and described 1 the right of fuselage is equipped with right hydraulic cylinder 8, described
1 top of fuselage is equipped with the oil pump 2 16 driven by motor 2 17, and the oil pump 2 16 is by being arranged on the reversal valve two of 1 upper end of fuselage
15 and left cylinder petroleum pipeline 1 and left cylinder petroleum pipeline 2 19 before left hydraulic cylinder 3 carries out fuel feeding to drive the piston of left hydraulic cylinder 3
Into or retreat, 1 top of fuselage be additionally provided with by motor 1 drive oil pump 1, the oil pump 1 is by being arranged on fuselage
The reversal valve 1 and right cylinder petroleum pipeline 1 and right cylinder petroleum pipeline 2 11 of 1 upper end to the right 8 fuel feeding of hydraulic cylinder to drive right hydraulic pressure
The piston of cylinder 8 advances or retreats, and the piston end of the left hydraulic cylinder 3 is equipped with left movable table 5, the right hydraulic cylinder 8
Piston end is equipped with right movable table 7, it is characterised in that：Linear displacement transducer 24, institute are also equipped on the fuselage 1
It is parallel with 3 axis of left hydraulic cylinder and in the same horizontal position to state linear displacement transducer 24, the straight-line displacement sensing
The movable part of device 24 links with left movable table 5, and linear displacement transducer 1, institute are also equipped on the fuselage 1
It is parallel with right 8 axis of hydraulic cylinder and in the same horizontal position to state linear displacement transducer 1, the linear displacement transducer one
9 movable part links with right movable table 7, and the motor 2 17 and motor 1 are variable-frequency motor.
The utility model is further set：The linear displacement transducer 24 and linear displacement transducer 1 can be
Magnetostrictive displacement sensor or metal film displacement sensor.
Utility model works principle and advantageous effect：It is synchronously moved using a kind of left and right movable table of the technical program
Dynamic hydraulic press, by the way that left linear position sensing and right linear position sensors is set to detect left movable table precisely in real time
With the position of right movable table, and by detection signal send electric-control system to, by electric control system controls motor two and motor one
Rotating speed, so as to adjust supply left hydraulic cylinder and right hydraulic cylinder fuel delivery, so as to adjust left hydraulic cylinder and right hydraulic cylinder piston
Amount of movement, that is, adjust left movable table and right movable table amount of movement, both make to drive horizontal punch shaping
Achieve the effect that synchro-feed during product, avoid since cylinder diameter error and motor revolution error etc. are comprehensive former when hydraulic cylinder is processed
Feed speed nonsynchronous shortcoming when the horizontal punch caused by is molded, fullness is good during three-way forming, reduces defective products, carries
High product quality.
