Description
Technical field
The invention belongs to field of machining, specifically a kind of jockey of three-shaft linkage cattle-head numerically controlled discharge machine main shaft.
Background technology
Electric discharge machine, is called for short EDM, full name Electrical Discharge Machining machining equipment, is mainly used in electric discharge machine processing.Be widely used in the manufacture of various metal die, plant equipment.The special process method of the galvanic action ablation conductive material that electric discharge machine produces when being and utilizing the two interpolar pulsed discharge be immersed in working solution, also known as electric discharge processing or galvanic corrosion processing.Carry out electric discharge machine and add man-hour, tool-electrode and workpiece connect the two poles of the earth of the pulse power respectively, and immerse in working solution, or working solution is filled with discharging gap.By gap automatic controlling system tool-electrode to workpiece feeding, when two interelectrode gaps reach certain distance, working solution punctures by the pulse voltage that two electrodes apply, and produces spark discharge.Instantaneous concentrated a large amount of heat energy in the micro-channel of electric discharge, temperature can up to more than 10,000 degrees Celsius, pressure also has and sharply changes, thus make the metal material of this point working surface local trace melt at once, gasify, and explosion type be splashed in working solution, rapid condensation, forms the metal particle of solid, is taken away by working solution.At this moment just stay next small pit vestige on the surface of the workpiece, of short duration resting of discharging, between two electrodes, working solution recovers state of insulation.And then, next pulse voltage punctures at another place that two electrodes are relatively close again, produces spark discharge, repeats said process.
Between retaining tool electrode and workpiece constant discharge gap condition under, ablation workpiece metal, while make tool-electrode constantly to workpiece feeding, finally just process the shape corresponding with tool-electrode shape come.Therefore, as long as change the shape of tool-electrode and the relative motion mode between tool-electrode and workpiece, the profile of various complexity can just be processed.Tool-electrode commonly uses that electric conductivity is good, the material of resistance to galvanic corrosion of higher, the easy processing of fusing point.
Electric discharge machine is a kind of self-excited discharge, and its feature is as follows: the voltage that between two electrodes of spark discharge, tool is higher before electric discharge, when two electrodes close to time, therebetween medium breakdown after, immediately flashing electric discharge.With breakdown process, two interelectrode resistance sharply diminish, the also sharply step-down thereupon of the voltage between the two poles of the earth.Flame path must extinguish afterwards in time in the maintenance time (being generally 10-7-10-3s) of short duration, just can keep " cold pole " characteristic of spark discharge (i.e. the heat energy of channel energy conversion has little time to reach electrode depth), make channel energy act on very low range.The effect of channel energy, can make electrode local be corroded.
Because electric discharge machine adds man-hour, the molten metal of partial melting, due to blast, splashes to electrode, needs to be disassembled, then clean, then reinstalled by electrode after causing electrode to complete one action electric discharge.Need to reorientate in this process, correcting electrode, cause many troubles.
