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 technical field.
Background technology
Traditional spark discharge processing carries out in the liquid medium having certain insulating properties, as kerosene, saponification liquor or deionized water etc.Oils working solution is hidden, is easily burnt, and adds the flue gas that man-hour, pyrolytic produced very large, serious to atmosphere pollution; Water-based working liquid for electrical easy-to-rust lathe, ablation amount is few, working (machining) efficiency is low.Therefore, a kind of excellent working performance is found and the Novel electric spark discharge working media of environmental protection is the target that research worker makes great efforts always.For many years, researcher both domestic and external has carried out improving and new trial from the single liquid working media of tradition of different angles to spark machined.The nineties in 20th century, Japanese scholars successfully achieves dry EDM, breaches the understanding that spark machined can only be carried out in liquid medium.The positive allusion quotation of state's branch conducts in-depth research this processing mode and achieves certain achievement.Zhang Qinhe first time is incorporated into ultrasonic vibration in EDM with compressed air medium technology, overcomes easy short circuit in simple EDM with compressed air medium and the low problem of working (machining) efficiency.But dry electrical discharge machining milling in gas still some problem not easily solves.First, chip removal problem, because chip removal in process is not smooth, galvanic corrosion product easily clings tool-electrode and workpiece, thus makes processing unstable, and working (machining) efficiency is low; In addition, the discharging gap of dry EDM is little, and the anti-breakdown strength of gas medium is less, and short circuit or even arcing events easily appear in process, require that the control of servo-drive system to gap of lathe is sensitive, therefore require very high to the servo performance of lathe.
Through finding the literature search of prior art, researchers investigated gas-liquid, the novel mixing two-phase working media such as liquid-solid.But for the spark machined of a special occasions, as non-conductive emery wheels such as discharge finishing resinoid bond or vitrified bonded grinding wheels, need to be mixed in media as well in conductive metal powder to realize the electric discharge processing of non-conductive or non-electrical conducting material.But in traditional Single Medium oil or in gas or gas-liquid, liquid-solid two-phase medium all cannot realize above-mentioned requirements.
The object of the invention is the nozzle mechanism proposing a kind of improvement.Achieve on the one hand and be mixed into conductive metal powder to realize the processing of non-conductive or non-electrical conducting material in gas-liquid medium; On the other hand, in nozzle mechanism, utilize spoiler to realize gas-liquid-solid multiphase medium mix and do not condense.
Summary of the invention
The object of the invention is to for working media Problems existing in existing EDM process, achieve heterogeneous micro-medium spark machined, provide a kind of and ensure that multiphase medium smooth delivery of power to component material each during surface of the work mixes and method and the nozzle mechanism of condensation does not occur.
Nozzle arrangements principal character of the present invention is, to be formed and before discharge nozzle mouth, eddy currents is arranged in the motion before two kinds or more single-phase mediums mix mutually at multi-phase mixture, thus obtains the medium fluid that phase constituent mixes.
For achieving the above object, the present invention is achieved by the following technical solutions, and mechanism comprises: baffle (3), nozzle body (2), spoiler (8), left end cap (1), nozzle (9).Baffle (3) is connected with thread forms with nozzle body (2), spoiler (8) connects with soldering form and is distributed in left end cap (1), arrange fumarole (4) at equal intervals in the upper end outer circumferential face of nozzle body (2), nozzle (9) is connected with thread forms with left end cap (1).
The present invention includes following two steps: airwater mist cooling medium tentatively mixes and the mixing of airwater mist cooling homogeneous media.
1. airwater mist cooling medium tentatively mixes
Liquid and solid dielectric enter the multiplexer channel (6) of baffle from the through hole (5) of baffle (3).Gas medium fumarole (4) on nozzle body (2) periphery enters nozzle body main channel (7), and the blending agent of liquid and conductive metal powder flows out and tentatively mixes in main channel 7 with gas medium from baffle passage (6) under pressure.
2. airwater mist cooling homogeneous media mixing
When the blending agent of gas, liquid and conductive metal powder flows through spoiler (8) position, its forms of motion is designed to eddy motion form, thus each phase medium composition is fully mixed.The medium fluid mixed enters electric discharge processing district through left end cap (1) top nozzle (9), forms spark discharge, thus realizes multiphase medium electric discharge processing.
Nozzle body structure of the present invention is simple, easily processing and manufacturing, use the present invention can generating component evenly and there is the airwater mist cooling fluid-mixing of good quality, be very suitable for spark machined that is non-conductive or non-electrical conducting material.
