Abstract
The invention discloses a nozzle mechanism of a multiphase medium electric spark machining method, which is used for providing a multiphase discharging medium for a discharging machining zone. The nozzle mechanism is composed of a turbulent flow sheet, a flow deflector, a nozzle body and a sealing plate. When the nozzle mechanism carries out multiphase medium electric spark machining, liquid, gas and solid media are input from a nozzle mechanism input hole and are stirred by the turbulent flow sheet in the main channel chamber of the nozzle; and after the mixture is fully evenly mixed, the obtained mixture is output from a nozzle on the other end of the nozzle mechanism so as to obtain the multiphase medium fluid of which the phase ingredients are evenly mixed, wherein the multiphase medium fluid is required for the multiphase medium electric spark machining technology. According to the nozzle mechanism, even gas-liquid-solid three-phase media are generated and input to an electric spark machining zone.
Description
Technical field
The present invention relates to the vital part design of heterogeneous hybrid working medium spark discharge process technology in the special processing technology field.
Background technology
Traditional spark discharge processing is in the liquid medium of certain insulating properties is arranged, to carry out, like kerosene, saponification liquor or deionized water etc.The oils working solution has flavor, burning easily, and it is very big to add the flue gas that man-hour, pyrolytic produced, serious to atmosphere pollution; Water base working solution easy-to-rust lathe, erosion remove and measure less, working (machining) efficiency is low.Therefore, the novel spark discharge working media of seeking a kind of excellent working performance and environmental protection is the target that the research worker makes great efforts always.For many years, the domestic and international research personnel have carried out improving and new trial from the traditional single liquid working media of different angles to spark machined.The nineties in 20th century, Japanese scholar has successfully realized spark machined in the gas, has broken through the understanding that spark machined can only be carried out in liquid medium.The positive allusion quotation of state's branch has been carried out further investigation and has been obtained certain achievement this processing mode.Zhang Qinhe is incorporated into ultrasonic vibration in the EDM with compressed air medium technology for the first time, has overcome easy short circuit and the low problem of working (machining) efficiency in the simple EDM with compressed air medium.But the still difficult solution of some problem of spark machined in the gas medium.At first, the chip removal problem, because chip removal is not smooth in the process, the galvanic corrosion product clings tool-electrode and workpiece easily, thereby makes processing unstable, working (machining) efficiency is low; In addition; The discharging gap of spark machined is little in the gas, and it is less that intensity is worn in the gas medium resistance, and short circuit or even arc discharge phenomenon appear in process easily; Require the servo-drive system of lathe that the control in gap is wanted sensitive, therefore the servo performance to lathe requires very high.
Through the literature search of prior art is found, researchers have worked out gas-liquid, new hybrid two phase working medias such as liquid-solid.But,, need in medium, sneak in the conductive metal powder to realize edm non-conductive or the weakly conducting material like non-conductive emery wheels such as discharge finishing resinoid bond or vitrified bonded grinding wheels for the spark machined of a special occasions.But in traditional single medium oil or in the gas or gas-liquid, liquid-solid two-phase medium all can't realize above-mentioned requirements.
The objective of the invention is to propose a kind of improved nozzle mechanism.Realized in the gas-liquid medium, sneaking into conductive metal powder to realize processing non-conductive or the weakly conducting material on the one hand; On the other hand, in nozzle mechanism, utilize spoiler to realize that gas-liquid-solid multiphase medium mixes and do not condense.
Summary of the invention
The objective of the invention is to problem to working media existence in the existing spark discharge process; Realized heterogeneous micro-medium spark machined, provide a kind of when ensureing multiphase medium smooth delivery of power to surface of the work each component material mix and the method and the nozzle mechanism that do not condense.
Nozzle arrangements principal character of the present invention is, heterogeneous blending agent form and the discharge nozzle mouth before, the eddy current form is arranged in the motion before two kinds or above single-phase medium mix each other, thereby obtains the medium fluid that phase constituent mixes.
For realizing above-mentioned purpose, the present invention realizes that through following technical scheme this mechanism comprises: baffle 3, nozzle body 2, spoiler 8, left end cap 1, nozzle 9.Baffle 3 and nozzle body 2 are connected with thread forms, and spoiler 8 connects with the soldering form and is distributed in left end cap 1, and outer circumference surface is uniformly-spaced arranged fumarole 4 in the upper end of nozzle body 2, and nozzle 9 and left end cap 1 are connected with thread forms.
The present invention includes following two steps: preliminary mixing of gas-liquid-solid three-phase medium and gas-liquid-solid three-phase medium evenly mix.
1. gas-liquid-solid three-phase medium tentatively mixes
Liquid and solid dielectric are from the multiplexer channel 6 of the through hole 5 entering baffles of baffle 3.Gas medium fumarole 4 on nozzle body 1 periphery gets into nozzle body main channel 7, and liquid-solid mixing medium flows out from baffle passage 6 and tentatively mixes in main channel 7 with gas medium under pressure.
2. gas-liquid-solid three-phase medium evenly mixes
Flowing through during spoiler 8 positions of gas-liquid solid mixing medium, its forms of motion is designed to the eddy motion form, thereby makes each phase medium composition fully mix.The medium fluid that mixes gets into the edm district through left end cap 1 top nozzle mouth 9, forms spark discharge, thereby realizes the multiphase medium edm.
Nozzle body of the present invention processing and manufacturing simple in structure, easy uses the present invention can generate the gas-liquid-solid three-phase fluid-mixing that composition is even and have good quality, is very suitable for spark machined non-conductive or the weakly conducting material.
