The utility model relates to a hydraulic control device with groups of hydraulic cushions working integrally of a hydraulic machine, belonging to the technical field of the hydraulic machine and comprising groups of hydraulic cushions and oil channels. The hydraulic control device is characterized in that each hydraulic cushion is provided with an independent hydraulic control mechanism connected with a hydraulic cushion cylinder and an ejection cylinder. The utility model is applicable to the drawing process of a large-tonnage long-mesa automobile and other longitudinal beam plates, ensures that sets of control systems work independently without interfering with each other, reduces the cost and is easy to press and mold complex workpieces.
Description
Technical field
The utility model belongs to the hydraulic press technical field, particularly relates to the hydraulic control device that a kind of hydraulic press is organized the hydraulic die cushion work in combination more.
Background technology
At present, the hydraulic press that is used for automobile industry has various ways according to the technological requirement of compacting.Automobile chassis is supporting, installation automobile engine and each parts thereof, assembly, forms the moulded of automobile, and accepts the power of engine, makes automobile produce motion, guarantees the important automobile component that normally travels.The automobile longitudinal girder hydraulic press can be realized the function such as stretching, bending, shaping to the U-shaped longeron.The automobile longitudinal girder of this press compacting is by about thick 8mm, and is wide to 400mm, grows to that 12 meters sheet materials after the punching are suppressed, the last shaping of stretch bending obtains.This just requires the hydraulic die cushion active force of hydraulic press to satisfy the long drawing process needs of 12m, select whole hydraulic die cushion, can reduce the intensity of sill greatly, increase the device fabrication cost, particularity according to technology, need the many groups of design hydraulic die cushion work in combination, and can be, select not hydraulic die cushion participation work on the same group arbitrarily according to the length difference of processing work.Existing control device can not satisfy hydraulic press reality of work demand.
Summary of the invention
The technical problem of the utility model for existing in the solution known technology, and provide a kind of hydraulic press to organize the hydraulic control device of hydraulic die cushion work in combination more.
The purpose of this utility model provides and a kind ofly is applicable to longeron sheet material drawing processes such as large-tonnage, long table face automobile, and has the hydraulic control devices of any work in combination of many group hydraulic die cushions.
The hydraulic control device of any work in combination of many group hydraulic die cushions is provided with a hydraulic control system that solely belongs on each hydraulic die cushion.In the control system, the hydraulic die cushion cylinder participates in the drawing process action, is to overlap independently mini system; The jack-up of liftout tank control hydraulic die cushion, return, be another set of independently mini system.By controlling the break-make of different magnetic valves, can select hydraulic die cushion whether to participate in work, and can guarantee the Synchronization Control of many group hydraulic die cushions action by adjusting choke valve.The stretching operating pressure of proportional pressure control valve YAC1 control hydraulic die cushion is selected the corresponding proportional pressure control valve of hydraulic die cushion, controls the pressure of itself.
This hydraulic control system adopts the identical control system of many covers, and is independent separately, do not disturb mutually, can use the use cost when reducing hydraulic press work according to need of work separately.Hydraulic die cushion can be selected any work in combination of many groups.
The technical scheme that the utility model is taked is:
Hydraulic press is organized the hydraulic control device of hydraulic die cushion work in combination more, comprise hydraulic die cushion and control oil circuit, be characterized in: hydraulic press has many group hydraulic die cushions, and an independently hydraulic control is set on each hydraulic die cushion, and controlling organization is connected with hydraulic die cushion cylinder and liftout tank.
The utility model can also adopt following technical measures:
Described hydraulic press is organized the hydraulic control device of hydraulic die cushion work in combination more, is characterized in: hydraulic control is equipped with the magnetic valve of control hydraulic die cushion action.
Described hydraulic press is organized the hydraulic control device of hydraulic die cushion work in combination more, is characterized in: hydraulic control is equipped with the proportional pressure control valve of control hydraulic die cushion stretching operating pressure.
Described hydraulic press is organized the hydraulic control device of hydraulic die cushion work in combination more, is characterized in: hydraulic control is equipped with pressure sensor.
Advantage that the utlity model has and good effect:
Hydraulic press is organized the hydraulic control device of hydraulic die cushion work in combination owing to adopted the new brand-new technology scheme of this practicality more, therefore can be according to the length difference of processing work, select not hydraulic die cushion participation work on the same group arbitrarily, and reduced the operating cost of processing.Hydraulic die cushion is divided in groups, and sill can be made box structure, has solved the Intensity Design problem of sill.Be easy to realize the compression moulding of complex part.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, hydraulic die cushion, 2, the hydraulic die cushion cylinder, 3, liftout tank, 4, pressure measuring tie-in, 5, pressure sensor, 6, Direct Action Type sequence valve, 7, proportional pressure control valve, 8, prefill valve, 9, individual event choke valve, 10, C type solenoid directional control valve,, 11, prefill valve control oil pipe 12, prefill valve suction ﹠ delivery oil hose, 13, check valve, 14, stacked unidirectional throttle valve, 15, J type solenoid directional control valve, 16, remaining fluid pressure pad control valve group, 17, liftout tank control oil pipe.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now also in conjunction with the accompanying drawings, be described in detail as follows:
