Abstract
The utility model relates to a novel ultrasonic vibration-pulse discharging composite working machine, which is composed of a common ultrasonic working machine tool and a set of attached DC power supply, and the positive and the negative poles of the DC power supply are respectively connected with workpiece and an ultrasonic vibrating tool head. The utility model has simple structure and can easily accomplish shaping processing to project ceramic, hard alloy, glomerocryst diamond, cubic boron nitride, special steel, etc. Meanwhile, the utility model has the advantages of high processing efficiency, good surface processing quality, low processing cost, etc.
Description
The utility model belongs to the forming processing technology field of difficult-to-machine material.It exactly is a kind of key equipment that is suitable for difficult-to-machine materials such as engineering ceramics, carbide alloy, polycrystalline diamond, cubic boron nitride and special steel material are carried out processing and forming.
Though existing ultrasonic carver tool machined surface quality is better, exists weakness such as material removing rate is low.Existing discharge (electric spark) machining exists many process factors of instability that make, pulse parameter for example, electrical guiding rule select improper or with in, during the accurate processing cavity of smart rule not towards liquid, increase along with working depth or area, cause skewness by the galvanic corrosion product that produced of discharge and by meeting such as carbon ink that pyrolytic in the working solution comes out because of spreading drainage difficulty, local concentration is too high, thereby destroyed the stable discharging state that point of discharge disperses when being evenly distributed, constituted point of discharge and concentrate, the galvanic corrosion product is concentrated, the vicious circle that point of discharge is more concentrated.The contradiction that above-mentioned reason causes makes not only that processing stability variation, pulse utilization rate reduce, process velocity is slack-off, even may reach the stage that can not continue to keep processing.Utilize the ultrasonic vibration and the compound action of discharge processing to improving the chip removal condition tangible effect to be arranged, the general practice is to make the tool heads of spark erosion equipment make ultrasonic vibration, but this method makes process equipment costliness, complicated operation.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, develops a kind ofly can improve working (machining) efficiency and machined surface quality and reduce equipment cost and the new Compound Machining equipment of processing charges.
This utility model realizes that in the following manner it is made up of the additional cover dc source of the logical ultrasonic machine tool of a Daepori, and positive and negative the two poles of the earth of dc source link with workpiece and ultrasonic vibration tool heads respectively.When anode-cathode distance hour, voltage across poles punctures the working solution medium of two interpolars and produces discharge; When anode-cathode distance was big, voltage across poles can not puncture the working solution medium of two interpolars, and then discharge process stops.During work, tool heads makes anode-cathode distance produce corresponding periodically-varied with supersonic frequency periodicity up-down vibration, under the voltage across poles effect, produces replacing of discharging and rest, and realizes the supersonic frequency droped beat impulse electricity of interpolar.Simultaneously, utilize the ultrasonic vibration of tool heads, by the hammering constantly of the abrasive grain in the working solution, impact surface of the work, the galvanic corrosion soften layer and the galvanic corrosion product cover layer of material surface removed.Pulsed discharge and ultrasonic wave processing are carried out simultaneously, and material removing rate and machined surface quality are improved, particularly for the hard brittle material better effects if of conducting electricity.Vibration frequency by adjusting tool-electrode and amplitude and interpolar DC voltage etc. can be realized the control to discharge parameter.
The utility model is owing to be made up of the additional cover dc source of the logical ultrasonic machine tool of a Daepori, so when difficult-to-machine materials such as engineering ceramics, carbide alloy, polycrystalline diamond, cubic boron nitride and special steel material are carried out processing and forming, have equipment simple, realize easily and advantage such as working (machining) efficiency height, machined surface quality and processing cost be low.
Description of drawings: Fig. 1 is the schematic diagram of this utility model, and 1 is supersonic generator among the figure, and 2 is the luffing bar, and 3 is tool heads, and 4 is the working solution medium, and 5 is workpiece, and 6 is dc source.
Provide a most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
One of J93025 ultrasonic machine tool; The AC rectification dc source one of design overlaps voluntarily, and its output voltage is stepless adjustable, and it is exported positive and negative the two poles of the earth and is connected with the ultrasonic vibration tool heads with workpiece respectively.Concrete processing conditions is:
(1). the working solution medium adopts 80
#B
4C: water=1: 4;
