And the device of Machining Technology with WEDM effect is promoted, it is specifically a kind of to be used for to-and-fro thread feed electric spark linear cutter
Working solution quantifies liquid-spraying control device.
Background technique
High speed to-and-fro thread feed electric spark wire-electrode cutting machine be China scientific research personnel end of the sixties in last century independent development,
Electromachining equipment with Chinese characteristics.High speed to-and-fro thread feed electric spark wire-electrode cutting machine is since generation, since its is excellent
Processing performance is rapidly developed and applies in China, has become indispensable important of China's mechanical manufacturing field
Equipment.
In Wire-cut Electrical Discharge Machining, the effect of working media: discharge channel is formed after being ionized breakdown, and is being discharged
After restore the state of insulation of interpolar rapidly；Compression is generated to discharge channel；It dishes out galvanic corrosion product；To electrode, workpiece
Play cooling effect.The study found that the parameters such as the dielectric properties of working solution, mobility, washing performance and hydrojet flow, hydrojet pressure
There is extremely important influence on interpolar discharge process.Currently, in high speed to-and-fro thread feed electric spark linear cutter, working solution
Generally use oil type, aqua type and compound working solution.In Wire-cut Electrical Discharge Machining, if working solution concentration proportioning does not conform to
It is suitable, flow set is unreasonable, the state of cooling of interpolar discharge channel, workpiece and electrode will be directly affected, leads to interpolar deionization
State deteriorating, and then the lasting progress of regular picture is influenced, processing efficiency is reduced, and interpolar ablation product can not be arranged in time
Out, it is finally deposited in finished surface and forms burn, surface quality severe exacerbation, while greatly reducing the durability of wire electrode,
Wire electrode can be blown when serious.
Currently, high speed to-and-fro thread feed electric spark wire-electrode cutting machine is generally using the common casting type of cooling, interpolar it is cold
But mainly working solution is brought into interpolar by wire electrode to carry out.If flow is excessive when working solution sprays, wire electrode may be made
Offset is generated, guiding discharge is uneven；Hydrojet flow is too small, then pours in joint-cutting without enough working solutions, interpolar is caused to be put
Electricity and cooling, chip removal condition are deteriorated, and cause process unstable or even cause fracture of wire.Therefore, it is necessary to cut to wire electric discharge
Cutting mill bed working solution hydrojet flow carries out quantitative control and adjusts, and real-time monitoring hydrojet flow, and police is issued in Traffic Anomaly
Report stops processing, is continued for guaranteeing that process can be stablized when serious.
Utility model content
It can not quantitatively control, cause in processing to solve working solution hydrojet in current to-and-fro thread feed electric spark linear cutter
Workpiece up and down hydrojet it is uneven, or even can not normal process, and then influence wire cutting technology index the problems such as, the utility model mentions
Liquid-spraying control device is quantified for to-and-fro thread feed electric spark linear cutter working solution for one kind.
To achieve the above object, the utility model adopts the following technical solutions:
Liquid-spraying control device is quantified for to-and-fro thread feed electric spark linear cutter working solution, it includes working liquid container, water
Pump, flow valve and water spray plate, are connected between water pump, flow valve and water spray plate by pipeline, and flow valve uses fixed flow control valve, should
Valve is adjusted for flow, and is sounded an alarm in Traffic Anomaly, and shutdown high speed is reciprocal when flow is lower than the alarm threshold value of setting
Wire electrical discharge machine tool power supply.
Further, flow valve is two, is respectively symmetrically installed on upper and lower line arm, and as close to water spray plate.
Further, filter is installed in working liquid container, to prevent flow valve and water spray plate from blocking, guarantees working solution spray
Outflow is consistent with setting value.
The utility model has the advantages that
1. the utility model can be according to the appropriate adjustments hydrojet flow such as discharge energy and thickness of workpiece, to guarantee in big electricity
There are enough working solutions to enter machining area when stream cutting and big thickness work piece cut.
2. the utility model effectively can not only be accurately controlled and be adjusted to the working solution flow in linear cutter
Section, and can be sounded an alarm in hydrojet Traffic Anomaly, guarantee that processing is continual and steady and carry out, while improving workpiece surface matter
Amount.
Detailed description of the invention
Fig. 1 is that quantitatively controlling for to-and-fro thread feed electric spark linear cutter working solution hydrojet flow for the utility model is shown
It is intended to；
In figure: 1- working liquid container, 2- water pump, 3- flow valve, 4- water spray plate, 41- water nozzle, 5- filter, 6- workbench.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
The utility model proposes one kind to quantify liquid-spraying control device for to-and-fro thread feed electric spark linear cutter working solution,
As shown in Figure 1, it includes working liquid container 1, water pump 2, flow valve 3 and water spray plate 4, between water pump 2, flow valve 3 and water spray plate 4 by
Pipeline is connected, and flow valve 3 uses fixed flow control valve, which is adjusted for flow, and is sounded an alarm in Traffic Anomaly, flows
High speed to-and-fro thread feed electric spark wire-electrode cutting machine power supply is turned off when amount is lower than the alarm threshold value set, is provided with water on water spray plate 4
Mouth 41, working solution quantify hydrojet and are sprayed onto workbench 6 by water nozzle 41.Preferably, flow valve 3 is two, is respectively symmetrically installed on
Upper and lower line arm, and as close to water spray plate.
Based on the above technical solution, filter 5 is installed in working liquid container 1, to prevent flow valve 3 and water spray plate
It is consistent with setting value to guarantee that working solution sprays flow for 4 blockings.
In high current processing (average processing electric current > 6A), due to the increase of discharge energy, the energy that is transmitted in working solution
Amount and heat also will increase, and interpolar working solution is caused largely to vaporize, thus wire electrode and workpiece are unable to get timely cooling, and
Galvanic corrosion product smooth can not be discharged, and influence normal process.Therefore, when high current is processed, appropriate adjustment flow valve 3, to obtain
Bigger working solution hydrojet flow is obtained, guarantees have sufficient working solution to enter joint-cutting.
When cutting big thickness workpiece, working solution brings interpolar by moving wire electrode, on thickness of workpiece direction, into
The working solution for entering interpolar gradually vaporizes under the high temperature action that discharges, in the latter half machining area on wire electrode traffic direction very
To no working solution, causes finished surface to generate burn, wire electrode is blown when serious.Therefore, big thickness work piece cut is being carried out
When, appropriate adjustment flow valve 3, increases hydrojet flow, guarantees that the machining area on whole thickness direction has working solution, with
Maintain normal process.
Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model
On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists
Within the protection scope of the utility model.
