Description

A kind of servo motor direct-drive bender hydraulic synchronization loop
Technical field
The utility model relates to a kind of hydraulic system, specifically a kind of servo motor direct-drive bender hydraulic synchronization loop.
Background technique
Bender adopts the texturing processing of relative movement realization to workpiece of upper and lower module, geo-stationary in its lower module working procedure, the slide block action of upper module then by being attached thereto, the action speed of slide block and stationarity determine primarily of the telescopic cylinder controlling slide block.Present bender is general all realizes synchronous working with crossing flow divider-combiner, carries out speed change by series flow control valve.But synchronous effect is poor, just bending difficult quality ensures; Oil hydraulic circuit is complicated, and service condition is harsh, and mechanical wear is large, consumes energy high, is unfavorable for saving, high-efficiency production.
Model utility content
The purpose of this utility model is to provide a kind of servo motor direct-drive bender hydraulic synchronization loop, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of servo motor direct-drive bender hydraulic synchronization loop, comprises fuel tank, oil hydraulic pump, AC servo motor, one-way valve, relief valve, three position four-way directional control valve, hydraulic synchronous motor, oil hydraulic cylinder, upper module.Oil hydraulic pump connects AC servo motor, the filler opening of described oil hydraulic pump is connected on fuel tank, described oil hydraulic pump oil outlet is connected with one-way valve, one-way valve is connected with three position four-way directional control valve, described hydraulic synchronous motor is connected with three position four-way directional control valve and oil hydraulic cylinder, and the extension bar of described oil hydraulic cylinder is fixedly connected with upper module.
As further program of the utility model: described oil hydraulic cylinder is two identical oil hydraulic cylinders.
As the utility model further scheme: described three position four-way directional control valve Median Function is M type.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts servomotor Direct driver oil hydraulic cylinder to carry out stepless change, environmental protection and energy saving, controlling is good, reliability is high, the synchronizing circuit formed additionally by hydraulic synchronous motor makes hydraulic cylinder synchronous better, thus makes the better effects if of bending.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of servo motor direct-drive bender hydraulic synchronization loop.
1-fuel tank, 2-oil hydraulic pump, 3-AC servo motor, 4-one-way valve, 5-relief valve, 6-three position four-way directional control valve, 7-hydraulic synchronous motor, 8-oil hydraulic cylinder, 9-upper module.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1, a kind of servo motor direct-drive bender hydraulic synchronization loop, comprises fuel tank 1, oil hydraulic pump 2, AC servo motor 3, one-way valve 4, relief valve 5, three position four-way directional control valve 6, hydraulic synchronous motor 7, oil hydraulic cylinder 8, upper module 9.Oil hydraulic pump 2 connects AC servo motor 3, the filler opening of described oil hydraulic pump 2 is connected on fuel tank 1, described oil hydraulic pump 2 oil outlet is connected with one-way valve 4, one-way valve 4 is connected with three position four-way directional control valve 6, described hydraulic synchronous motor 7 is connected with three position four-way directional control valve 6 and oil hydraulic cylinder 8, and the extension bar of described oil hydraulic cylinder 8 is fixedly connected with upper module; Oil hydraulic cylinder 8 is two identical oil hydraulic cylinders, and three position four-way directional control valve 6 Median Function is M type.
Working principle of the present utility model is:
Oil hydraulic pump 2 is inhalant liquid force feed from fuel tank 1, and enters oil hydraulic cylinder 8 by one-way valve 4, three position four-way directional control valve 6, hydraulic synchronous motor 7 successively, carrys out the lifting of hydraulic control cylinder 8 by controlling three position four-way directional control valve 6, thus controls moving up and down of upper module 9.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
