Abstract
The present invention relates to a hydro-electric cutting method of metal, which can be used for the technical field of metallic material cutting. The present invention utilizes sodium chloride electrolytes as media, an electric arc is generated between two electrodes under the action of a cutting power supply, partial metal is melted instantly, melted metal at the place to be cut is rapidly blown and ejected out of the cutting gap by high pressure tricklet of the liquid, and the purpose of cutting the metal is achieved. The present invention has the advantages of low cost, simple technology, easy popularization, etc., and is suitable for cutting various metallic materials. The present invention has good adaptability to irregular workpieces and bad operating environments.
Description
Technical field
What the present invention relates to is the method in a kind of welding and cutting technique field, especially a kind of metal hydro-electric cutting method.
Background technology
Known metal cutting method has a variety of, and gas flame cutting, plasma cutting, laser cutting, electric arc cutting or the like are arranged.A lot of methods all are to lean against the local heat that produces of metal, and blow molten metal off and form the cutting seam with gas.The metal cutting method that has traditional most employing now is the flame cutting method, and this method is in the limitation that is cut with to some metal material.
Find by prior art documents, technical characterictic and the technology characteristics to Abrasive Water Jet Machining in " technical characterictic of Abrasive Water Jet Machining and technology characteristics " (being published in " the accurate manufacturing technology of aviation ", 2005 the 1st phases) such as Yang Lin is described.During cutting, utilize the little ablation of high frequency of high speed abrasive particle that material is cut.But this cutting technique is subjected to the influence of several factors, exists the cutting profile precision low and cutting section is coarse and off plumb is not enough usually, and there is certain degree of difficulty in the problem that solves accurately cutting under existing technical conditions.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of metal hydro-electric cutting method is provided, reduce energy resource consumption when making its cutting, technology is simpler, can cut various metal materials substantially, reaches the purpose of finishing Metal Cutting.
The present invention realizes by following technical scheme, the present invention utilizes a kind of sodium chloride solution as media, under the effect of cutting power supply, make between two electrodes and produce electric arc, the instant melting localized metallic, and use the high pressure thread of this liquid rapidly, the metal of place to be cut molten condition is blown penetrate the cutting slit, to reach the purpose of cutting metal.
Below further limit as follows by concrete steps to the present invention:
(1) cutting is 20～40% with sodium chloride electrolyte concentration.
(2) with electrode of cutting power supply be cut metal and be connected, make between itself and the cutting gun and can form the galvanic circle.
(3) with cutting gun to metalloid cut place, start power supply, make its cut place produce electric arc.Killer voltage is 20～40V, and cutting current is 30～500A.
(4) the high pressure conducting liquid penetrates with the thread form, cuts into the slit rapidly under the effect of arc heat deposite metal, to reach the purpose of cutting metal.The pressure that the high pressure conducting liquid forms during cutting is at 10～100 atmospheric pressure.
Described cutting power supply is meant incisory cutting power supply with dropping characteristic.
The present invention utilizes the electrolyte solution of conduction to replace common wire, and is theoretical according to the electric arc cutting, utilizes electrolyte solution as conductive carrier, and starting arc produces high heat, makes the metal local melting.With the form of conducting liquid with directed high pressure thread, the partial melting metal is washed out, form the cutting slit, finish cutting process.The cutting of common electric arc be workpiece and welding wire ignition tip as two electrodes, the liquid hydro-electric cutting method also be workpiece and ignition tip for producing two electrodes of electric arc, just the ignition tip here is not to send wire but high pressure conducting liquid shower nozzle.
The present invention has that cost is low, and technology is simple, and advantage such as popularization is applicable to the cutting of various metal materials easily, and to workpiece in irregular shape, the occasion that operating environment is more abominable has good adaptive capacity.
